Gabriela "Gabby" Dawson (Seasons 1–6, Guest Season 7) is one of the few females at Firehouse 51 and was introduced as the Paramedic in Charge of Ambulance 61. Dawson has recently found herself in trouble for leaping before she looks on various calls, which leads to her being written up several times. She was partnered with Leslie Shay for much of the first two seasons and they shared a close friendship but their friendship was strained after a call went bad. Both were well-liked by the all-male crew at 51, who are all very protective of them. She transfers to Truck 81 in season 3 after passing firefighter training. In season 4, with the announcement of her pregnancy, she was transferred to the Office of Fire Investigation (OFI) to work as an arson investigator.
Off-duty, she runs Molly's, a small bar jointly owned by her, Otis and Herrmann. The bar is also popular with her brother's colleagues from the 21st District and the staff at Chicago Medical Center, whom the paramedics regularly come into contact with. She is usually in charge of the food and beverage aspects, while Otis and Herrmann deal with the business and marketing aspects. Not long after Molly's opens, Dawson befriends Jay, who was a regular customer at Molly's, but breaks up with him after finding out that he was a "spy" for Arthur, a mobster-cum-landlord who repeatedly harassed them. She threatens to call the cops, only to find out that Jay was actually her brother's colleague and undercover cop Detective Jay Halstead. Halstead eventually arrests Arthur and Molly's remains open.
The younger sister of Detective Antonio Dawson, a main character in spin-offs Chicago P.D. and Chicago Justice, Gabby is well known for being able to hold her own in a largely male-dominated occupation and an all-male firehouse; she and Shay were the only women at 51 until Brett was assigned to Ambulance 61 in season 3.
Dawson shared a close friendship with long-time colleague Matthew Casey even though they were each in relationships with different people. Later, she and the new Candidate Peter Mills bond over their mutual love for cooking and begin a relationship in secret. When their relationship is brought to light, Casey seems to be jealous and pulls rank to keep them apart at work. She later discovers that Boden had had an affair with Mills's mother, and she keeps this knowledge from him. When he finds out that she had known about it and that she still has feelings for Casey, he ends their relationship but they remain mutual friends. She had a brief relationship with Detective Jay Halstead at the beginning of season 2 but they mutually part ways. Following Casey's near-death accident in the season 2 episode "Not Like This", Dawson and Casey start a very serious romantic relationship and Casey proposes to her. She later is a Candidate in the Fire Academy. She fails her physical exam by several seconds, after injuring her ankle. In season 3, she has passed the Fire Academy. However, her relationship with Casey poses a problem due to fraternization rules and she is initially assigned to Firehouse 105 in Austin under Casey's nemesis Lieutenant Welch. Welch was against her assignment to his truck company due to a past bad experience with a female firefighter. He fills the spot and she is assigned as the Candidate on Truck 81, under Herrmann's supervision. During her first few weeks on the job, Casey is extra protective of her, much to Herrmann's frustration, but she eventually settles in. In season 4, she suffers a miscarriage. Her return to duty coincided with Chief Riddle's quest to oust and make an example of Chief Boden so that he can make Fire Commissioner.
In season 5 Dawson decides to foster Louie, the child of one of the victims of a fire that Truck 81 attended, and the decision put her at odds with Casey, who had doubts about having a child in their lives. Casey moves back in with her again and accepts Louie in their "family". After a close call involving both her and Casey, Dawson begins to consider the fact that if both of them remain at Truck 81 there was a possibility Louie could be orphaned. She decides to return to Ambulance 61 after the spot opened up when Borelli returned to truck. She and Casey marry in the 100th episode as part of their plans to speed up Louie's adoption. However, Louie's biological father, who had up until then been listed as "unknown", shows up at both their apartment and the firehouse demanding to see his son. Louie eventually moves in with his biological father and paternal relatives. Despite this, Dawson and Casey remain together and have been seen wearing their wedding rings since.
Dawson and Casey reconnect after Gabby almost loses him in the fire that ended season 5. Gabby meets a girl named Bria in a fire, she finds out her father is addicted to meds and tries to help her, after not talking to Casey about it and instead talking to Severide, Casey finds out what they are up to and is upset. Dawson decides to let Casey help with Bria.
Dawson's old fling, Jake Cordova, comes to the firehouse since Otis was hurt. things get crazy with Dawson. She doesn't tell Casey right away, which makes him mad when he finds out. When Otis is allowed back on truck everything goes back to normal, or that's what Dawson and Casey think.
Dawson gets a call from Bria asking to help her with some "girl problems" so Dawson does, she helps Bria get ready for prom, Casey decided that they could ride in the truck so with Stella driving, Bria and her date ride to prom in the truck. While watching the truck pull away Dawson tells Casey she wants to start trying again. After trying for a while Dawson wants to get to the doctor to make sure everything is okay and to move the process along faster.
Finding out Dawson has an aneurysm that could burst with pregnancy, Casey and Dawson stop trying. Dawson tells Casey she wants to take the risk but Casey says no, not wanting to lose her. He brings up adoption which sets Dawson off since she doesn't want to go through the same thing as they did with Louie.
In the last episode Dawson is offered a job in Puerto Rico which she turned down at the beginning of the episode. During the episode Brett and Dawson fight on one of the calls and then Dawson and Casey fight when they get home.

Paramedic in charge (S5 - Present)
- Portrayed by Kara Killmer
Paramedic Sylvie Brett (season 3 – present) joined Ambulance 61 following Shay's death. Initially 51 was not enthusiastic about her arrival as most of the crew had known and worked with Shay for a long time and were still getting over her death. Later in season 3, Jessica "Chili" Chilton replaces Dawson as the new Paramedic in Charge (PIC) following Dawson's transfer to Truck 81 and they strike up a friendship. However, when the house gets toned out for a call and Severide first sees her after returning from over a month long break, he does a double take while she's walking away from him, noticing the resemblance between her and Shay. He sees her face then gets on the truck. This then escalates to the point when he tries to hang out with her, slightly using her to get past Shay since they look alike. It takes him a long time to get past this until he gets married to Brittany. She worked alongside Peter Mills when he replaced Dawson after she transferred to Truck 81 as a candidate. Mills was not cleared for duty after a head injury at the explosion where Shay died. Sylvie was upset that Mills had chosen to go to North Carolina near the end of Season 3 and during his goodbye party, she breaks down in tears and hugs Mills goodbye. In mid-season 4, Chili leaves to enter an alcohol rehab program and Brett becomes the new PIC. The character has appeared on the spin-off Chicago P.D. as the first responder on scene, crossing paths with members of the Intelligence Unit.
Brett is a small-Midwestern-town girl from Indiana and is a "runaway bride" who goes "up I-65 to Chicago" to escape her ex-fiancée Harrison after their engagement fell apart. However, her husband to-be finds her working at 51 and comes to visit her. He apologises in front of everyone for leaving her before their marriage, revealing that he's the one who had cold feet. Nonetheless, she gets back together with him briefly until she realizes he has a very overbearing nature. As he psychologically tries to dominate her by telling her how she should feel and where she should work. She tells him she's happy in Chicago but he tells her she isn't. She breaks up with him again and he leaves. She was put up for adoption as a child and never knew her birth parents. Initially she has difficulty adjusting to city life due to her naivete, as shown by the fact that she leaves cash out on the table with the windows open and rented an apartment in a neighborhood known for crime because the rent was cheap. She shared an apartment with Gabby Dawson when the latter's relationship with Matthew Casey had cooled.
During a call, Sylvie gets attached to a baby she delivered to a gunshot victim mother who died in the ambulance. She visits the baby in the hospital several times until Chief Boden finds out and tells her to let it go and so does Chili. However, she still goes back, where she meets Dr. Charles (Chicago Med). He tells her secretly to check the father's details while the receptionist is out. She goes to see him and tells him about the son but he ignores her. However, when she comes back to see the baby yet again, the dad is there and thanks her. She and Chili also help host a wedding, where she sings.
Sylvie joins the best rated Zumba club she found on Yelp and finds that the instructor is none other than Cruz. They agree to keep it a secret as long as she can teach him how to cook since he's opening Molly's 2, but she ends up telling Casey due to his misunderstanding of the relationship of the two. She asks if he keeps it a secret but he ends up telling it to Dawson, then Hermann, then Mouch, then everyone else. Joe then asks Sylvie out and she rejects him. However, she accepts some time later and they start dating. She appears to have a romantic interest in Officer Sean Roman from Chicago P.D. as they share a kiss in the season 3 finale of Chicago Fire. She reveals her feelings for Jimmy Borelli, when she finds out that Jimmy is leaving, she confesses her feelings for him, which she later tries to cover up when she finds out he is staying in the CFD and working alongside her as her new partner. In season 5, both Chili and Jimmy leave as paramedics, leaving Dawson to take their spot and work alongside Brett. During one of the cases, Gabby's brother Antonio shows up and Sylvie instantly develops a liking towards him. After some consideration, she asks him out but he refuses, saying that his breakup with his ex-wife is still on his mind and he doesn't want her mixed up with this. She responds by saying that she doesn't mind and as a result, they start going out. She begins a relationship with Antonio Dawson, Gabby's older brother. In the end of "An Agent of the Machine", Sylvie tries harder to impress Antonio's son Diego, who likes to play chess and whom she doesn't connect with. Otis teaches her and Antonio asks her later to take care of Diego when he's suddenly called to work. This upsets Sylvie and when Antonio shows up, she tells him what happened and he apologises and she adds that she doesn't want to be in the middle of his fight with him and his ex-wife. He tells her that he warned her before this but she replies that she didn't expect to be directly confronted by Laura. He lashes out and she breaks up with him. Antonio later shows up at Sylvie's door and apologises but she is still angry. She later tries to get her mind off Antonio by doing extra exercise at the firehouse, trying to find online makeup classes and changing her look and even learning German. Dawson feels bad and tries setting her up with people Casey knows but Casey doesn't want to get involved in her love-life. In "A Man's Legacy", while in the hospital, she sees Antonio with his sister after visiting his father, she talks with him indicating that the relationship is getting close to reconciliation. In "Foul is Fair", it was revealed that Brett breaks up Antonio, after she develops cold feet about their relationship. At the end of "Hiding Not Seeking", she has a one-night stand with Antonio in his car. In "Looking for a Lifeline", Brett confides in Dawson who suggests that Brett might be pregnant. But she takes a pregnancy test and the test came up negative and she was relieved. In "The Chance to Forgive", Brett wanted to spend the rest of her life with Antonio Dawson but soon finds out that he had been set up on a blind date by someone in his department. After the discovery, she cleans up her locker with anything that had to with Dawson and declaring that she is a new person.
In "The Grand Gesture", she was distraught over a stabbing victim who died in front of her after being stabbed by a mentally unstable man. She was seen crying in her car after the call. She eventually explodes when Dawson also becomes angry and yells at her when she grabs scissors instead of gauze during a call. This officially ends their partnership. At the end, Cruz consoles her.
In "A Closer Eye", she turns every paramedic that she was partnered with, believing that Dawson will come back. She was then partnered by Boden, with Emily Foster. At first, the chemistry between the two was a little rocky. In "Going to War", she confronts Casey about letting Dawson leave. He replied that there was nothing anyone else could have done. He also gives her a goodbye gift from her recently ex-partner: a photo of the pair together, on the back of which is written a note: “Love you, partner, and always will.”
In season 7, she dates Kyle Sheffield, a chaplain with the CFD. They break up in "Fault in Him", with Kyle citing that their relationship has led to firefighters not willing to confide in him, after Brett asks him to talk to Casey about a bad call he experienced. In "I'm Not Leaving You", Kyle comes to 51 and proposes to Sylvie in front of everyone after he tells her he's moving to Indiana. Brett accepts his proposal.

Chief Wallace Boden (season 1 – present ) is in charge of Battalion 25 stationed at Firehouse 51. He is a scarred veteran of the fire department and served with Benny Severide and Henry Mills, the fathers of his subordinates, Kelly Severide and Peter Mills, respectively. Chief Boden has unwavering dedication to the firefighters under him and has earned their loyalty and respect. He will go through great lengths to protect the integrity of the firehouse and his men, even if it means having to antagonize them by disciplining them. His career was threatened after a feud with Gail McLeod when she tried to overthrow him and install his former colleague Benny Severide as the chief of Battalion 25. Boden refuses to give up his house and fights for it. Later she tries to "justify" the closing due to an incident at a call where the victim had to be cut out of a $40,000 trash compactor. McLeod is eventually removed and Firehouse 51 remained open. Despite his serious exterior, he is open to advice from his men, particularly regarding his personal life; for example, he asks Herrmann, who has five children, for tips on how to deal with his pregnant wife Donna and infant son and Mills for some insight while he was dating Donna. He also views his firefighters as his extended family, especially his two lieutenants, Matt Casey and Kelly Severide, who view him as a mentor and fatherly figure at 51.
Boden is said to have been divorced twice and has a stepson Jimmy by his estranged second ex-wife. He has a ex-wife, Shaunda, and a stepson, James, who appears in season 1 and later in season 5 who he doesn't see much. Shaunda owns a pancake and waffle restaurant on the south side of Chicago that Wally Bo and his crew often visit. In season 2, while intervening on a fire in a building he met one of the residents, Donna Robbins, an elementary school teacher. Being attracted to each other, they started dating until Boden broke off, being afraid of screwing up the relationship like he always does. After a while, he met Donna again and learned that she's pregnant with his child. Soon after, he proposed to Donna, arguing that it would be better for the child since he would be able to support them financially. She turned him down, not convinced by his non-romantic point of view. Confused, Boden goes to Mills for some explanation. He understood then that he didn't speak about his feelings and, in full uniform, proposed to Donna again, successfully this time. He marries Donna Robbins, an elementary school teacher, in a small ceremony at the firehouse, the same day as her parents years ago. He had feelings for her for some time but was only convinced to propose to her after she tells him that she was pregnant and with the encouragement of his firefighters. Herrmann was his best man and organized the wedding ceremony in front of firehouse 51 with Mills as clergyman. Donna is having some difficulties with her pregnancy, having a risk of fatal blood loss. At first she refused to know the baby's gender unlike Boden who'd have liked to know. She revealed to him later that they are expecting a boy. They have a son Terence who was born in Squad 3's truck en route to the hospital(Chicago Med). He had an affair with Ingrid Mills, Peter Mills' mother, when she and her husband were separated. As soon as he realized they had still feelings for each other, he stepped back. Mills was very upset when he learned about the affair and remained angry at Boden for a long time. He currently has a bad relationship with Benny Severide due to their opposite views on the heroic death of Henry Mills. Benny Severide argued that Mills' death was due to his attempt to impress Boden who was having an affair with his wife. In season 5 Jimmy, now a high school student, comes to live with him and joins the crew at 51 to "observe" what life was like as a firefighter. However, Severide and Cruz both suspected that Jimmy was not telling the whole story. Jimmy finally confesses that his mother's new boyfriend had been secretly abusing him physically whenever she was not around. In "Ignite on Contact", his wife Donna was almost killed when the high school she teaches, was on fire and one of the teachers was seriously injured. It was later revealed to be arson and one of her students was a suspect.
In "The One that Matters the Most", Boden contemplated moving up in rank after the CFD was considering promoting him. In "One for the Ages", after being encouraged by Casey and Severide to seek a promotion in "The Unrivaled Standard", he decides to run for Fire Commissioner of Chicago with the Mayor of Chicago endorsing him. In "The Grand Gesture", his run for the fire commissioner was stopped when allegations of bribery came into light. He then lost the campaign to Chief Carl Grissom when he became elected Fire Commissioner from the Mayor.
Boden's father Wallace Sr. (Richard Roundtree) lives in Orlando, Florida. In the episode "Ambush Predator", Boden finds out that his father has stage four cancer and was given four months to live. Wallace Sr. peacefully passes away at his son and daughter-in-law's home at the end of the episode "Call It Paradise".
In Season 1, he got close to Ernie a teenager he saw several times on garbage fire interventions. Thinking the boy may be responsible of those fires, he invited him to the firehouse to investigate with Herrmann's help. It turned up that Ernie was under his uncle Ray's influence and finally died in a fire set by Ray. His death devastated Boden. In Season 4, Boden invited Capt. Dallas Patterson to command Squad 3 after Kelly Severide was demoted from lieutenant to firefighter. Boden and Patterson were later seen playing poker with Sgt. Whitaker of Chicago P.D. Boden faced legal troubles after a neighbor, Serena Holmes, accused him of home invasion and assault. Holmes had moved into the apartment next to Boden and Donna as a temporary Airbnb tenant and requested Boden's help after locking herself out of the apartment and claiming that she had left the stove on. Boden forced entry into the apartment at her request, only to find the stove off and Holmes acting seductively. She offered him a glass of wine, which he declined before leaving. Later, a detective with Chicago P.D. confronts Boden at home and says that Holmes claimed that Boden broke into her apartment and assaulted her with a wine bottle. The detective produces photographs that show an obviously battered Holmes. Knowing that he did not commit the crime, Boden enlists the help of Firehouse 51 to uncover the truth. Boden first suspects that Deputy District Chief Ray Riddle, who had been attempting to remove Boden from his post, may have put Holmes up to the job of sullying Boden's reputation. But with the help of Kelly Severide's ex-girlfriend, attorney Jamie Killian, it is revealed that arsonist Roger Maddox - who was set to go to trial for his crimes, and who was being represented by Killian - had hired Holmes to accuse Boden. It is also revealed that Maddox set out to discredit members of the department's Office of Fire Investigation (OFI), including captains Greg Duffy and Suzie Wilder, who were to testify against Maddox at the trial.

Lieutenant (Season 7 Episode 4 Onwards)
- Portrayed by David Eigenberg
Lieutenant Christopher Herrmann (season 1 – present) is one of the senior firefighters of Truck 81. He is the third most-experienced firefighter at 51 (after Mouch and Boden), having served for nearly two decades. He passed the Lieutenant's promotion examination during season 2 episode "Virgin Skin" and was wait-listed until the Season 7 episode "This Isn’t Charity" where he was finally promoted. He is generally considered Casey's de facto right-hand man on the job by the rest of the truck company, as shown by the fact that he was made Acting Lieutenant whenever Casey is off-duty or unavailable and also oversees Candidates assigned to Truck 81. Casey once described him as "the heart and soul" of Firehouse 51.
Outside his job, Herrmann was a self-described "day trader". There is a running gag in the show about how Herrmann would come up with ideas to solve his various problems and they would often backfire or go completely wrong. His sharp instincts on the job are in stark contrast to those when he is not at the firehouse, which include taking on several "get rich quick" schemes that have left him financially precarious, but had seemed to have finally made a good investment opening "Molly's Bar" along with Dawson and Otis, after putting out a fire at the location and buying it out. Molly's was nearly another of his failed investments as paperwork mishaps, building code issues and competition from a large sports bar located across the street threatens closure. In season 1, one of his investments goes bad and he loses his home to foreclosure, forcing him and his family to move in with the in-laws for several months. In season 4, he attempts to run a rude and condescending couple out of town, after they sued Molly's for "breaching" the city's noise limits, by hosting karaoke night at Molly's and belting out the chorus of "Don't You (Forget About Me)" over the microphone. He also developed a near father-daughter relationship with Chili in season 3 as he immensely helps her design her dad's business idea, helping to fund and create it. The relationship greatly fades away by Season 4 as she breaks away from him and the rest of 51 after her sister's death and spirals into alcoholism. In season 5 he and Otis bring a discarded table tennis table back to the firehouse and end up smashing out a glass panel after the former challenges the rest of Truck 81 to a "show down".
Until the birth of Boden's son with his current wife Donna, Herrmann was the only character on the show who was married with children. As such, he has a soft spot for young victims. In season 3, after learning that a young boy he had rescued died from a fire caused by his negligent alcoholic father, he had to be physically restrained by Casey from hitting the father in a fit of rage. Boden sought his advice many times about dealing with his pregnant wife and infant son. Herrmann is also the first to notice Dawson's strange behavior prior to her and Casey revealing her pregnancy to the crew.
Herrmann is portrayed as a hands-on father and devoted family man who considers his fellow firefighters and paramedics at 51 as part of his extended family; most of his colleagues have babysat his five children at some point and Herrmann has no qualms about discussing the children with his wife in front of them. In the episode "Path of Destruction" it is stated that he and his family live in the West Lawn area of Chicago. At the start of season 1, Herrmann and his wife Cindy have three sons and a daughter. In season 4 he stated that they have been married for twenty two years. Cindy had suffered a miscarriage before their first child Lee Henry. Their fifth child and youngest son was born in the season finale after a difficult birth. Severide and Shay are named as godparents. Herrmann is shown to be a doting father and husband who often speaks of his family. All five children were christened into the Catholic Church. Because Cindy is Catholic, she does not use birth control, which led to Herrmann's much derided decision to do a vasectomy as his 20th anniversary present to her so that she does not have to go through another pregnancy without compromising her religious beliefs. His co-workers all tried to dissuade him from going through with it but their "concern" backfires against them as Cindy reacted by laughing and hugging her husband.
When Rebecca Jones joins firehouse 51 as the new candidate, her cocky behaviour doesn't sit well with any of the members. However, it's revealed that he father is constantly trying to stop her being a firefighter and shutting down all of her ambitions, which eventually drives her to suicide. Herrmann and Mills get into a heated argument following the cause of her suicide. Mills accuses Herrmann and the others of being uncaring and inconsiderate, which Herrmann fights against until revealing his guilt in that he saw her the night before and wondered whether him saying something to her would've changed the outcome. They get past this together. Herrmann looks into expanding Molly's into a franchise and pitches his idea to the group. Cruz and Mouch want in and after a good presentation, Herrmann happily accepts their proposal into expanding Molly's into a truck this time.
Herrmann and Dawson also have tensions between them when she reveals she's going to be a firefighter at the end of season 1 from a bad experience with a female firefighter. When she finally passes her physical exam and becomes a candidate, Welch rejects her from 81 and quickly recruits a male candidate, which upsets her so Boden overlooks her and Casey's relationship and lets her be the new candidate at 51. This doesn't sit well with Herrmann as Casey makes a habit of overlooking all of her mistakes, forcing him to do the same and not question her. She reveals afterwards that she has been deliberately making mistakes in hopes that someone will overlook their friendship and correct her.
When Chili joins 51, despite the at-the-time cold welcome, she tries to make friends but doesn't have a lot in common with the others. This is until she reveals she's in-midst of creating and designing a button on the side of beverages to cool them instantly in 5 seconds. Being a business investor, Herrmann immediately jumps in and tells her she can sell it at Molly's as soon as she's finished. He helps her a lot until Sylvie and Dawson tell him to calm and slow down since Chili's spending all of her money on it without leaving any to pay her bills. He says this to Chili who thanks him for his help, saying Herrmann reminds her of her own father who died but created the idea in the first place. They get emotional and he says he will be right with her.
Herrmann and Cindy gave Chili Molly's funds to help her idea, for which she is very thankful. They then celebrate their success when she finishes her design and test to see that it works, which it does. However, she's left deeply hurt and upset when they find that someone else has already created and launched it on TV. She cries but Herrmann tells her she will definitely come up with something else and hugs her.
In season 1, Otis, Herrmann and Dawson buy a bar which they call Molly's. They had been called to a fire there and the owner wanted to sell it and move to Miami. After agreeing to buy it, they discover that a local mobster named Arthur had conned his way into being offered a "minority" stake. Arthur repeatedly harasses the threesome, even nearly setting Dawson on fire before Detective Jay Halstead takes him down and arrests him. After much difficulty, Molly's has become an established bar and is popular with firefighters and cops (it is featured multiple times in spin-offs Chicago P.D. and Chicago Med). After Captain Patterson, then chief, tells Cruz to tell Freddy he can no longer come to 51, Herrmann happily offers him a job at Molly's to get him out of the gang life he wants to escape. He's friendly towards him. At the end of "Short and Fat", Herrmann was stabbed by Freddy, Cruz's friend, at Molly's bar after he told a joke that Freddy took as an offense. The doctors reveal that he's lost a lot of blood and it would be difficult for him to pull through. Things heat up between Rhodes (Chicago Med) and Severide after he accuses him of not treating Herrmann properly after Halstead (Med) says something about this to one of the others. However, he pulls through and is back to 51 soon. Although, the encounter leaves him with a shaky feeling and he is constantly on edge his first shift back - constantly worrying about Cindy and his kids even though he tries to hide this. He also tells Cruz not to mention Freddy to him again. He was later discovered by his co-workers in the crossover episode "The Beating Heart" and was rushed to Chicago Med. Freddy was later arrested by Chicago PD detectives, after he was rescued by firefighters from hanging on the fire escape. He makes a statement against Freddy in court. In "Not Everyone Makes It", he had to testify against Freddy about the events that led up to the stabbing. Freddy's father, also in prison, requests Herrmann to see him. Cruz tells him not to and he says he won't but ends up going. He reveals that he used to beat Freddy and is the reason why he is the way he is.

- Portrayed by Dora Madison
Jessica "Chili" Chilton (season 3–4) replaced Peter Mills as the new Paramedic in Charge (PIC) in season 3 after the latter leaves the CFD. The crew at 51 were initially lukewarm to her as they were still getting over Mills' departure, having warmed up and grown to like to their former Candidate.
She came from a dysfunctional family; her parents divorced not long after marrying and her mother became a heroin addict and eventually abandoned the family. Her sister Alissa lives in Kansas City and they lost contact. Prior to being cast on Chicago Fire, Madison actually appeared as Alissa on Chicago P.D. in the episode "Call It Macaroni". Alissa was one of Antonio Dawson's CIs and, using the cash paid by the district for her tip, leaves Chicago to start a new life. When Chili joins Firehouse 51, despite the at-the-time cold welcome, she tries to make friends but doesn't have a lot in common with the others. This is until she reveals she's in-midst of creating and designing a button on the side of beverages to cool them instantly in 5 seconds. Being a business investor, Herrmann immediately jumps in and tells her she can sell it at Molly's as soon as she's finished. He helps her a lot until Sylvie and Dawson tell him to calm and slow down since Chili's spending all of her money on it without leaving any to pay her bills. He says this to Chili who thanks him for his help, saying Herrmann reminds her of her own father who died but created the idea in the first place. They get emotional and he says he will be right with her. Herrmann and Cindy gave Chili Molly's funds to help her idea, for which she is very thankful. They then celebrate their success when she finishes her design and test to see that it works, which it does. However, she's left deeply hurt and upset when they find that someone else has already created and launched it on TV. She cries but Herrmann tells her she will definitely come up with something else and hugs her. At the start of Season 4, Chief Boden is under watch and investigation up to the point he is arrested and demoted from Chief and replaced by Dallas Patterson. When Casey then sees Chili and Jimmy hanging out too closely with each other around the firehouse, he tells Jimmy to slow things since it isn't appropriate while they are under watch, especially with Patterson. Jimmy tells Chili this and she is okay. However, she shows inappropriate behaviour again and when they're caught by Patterson, he gets worried but she laughs it off, which angers him and they break up.
Throughout the next few weeks, Chili behaves erratically and is constantly angry and raging at anyone who asks her anything or questions her. Sylvie assumes it's the breakup or the fact that Herrmann is in hospital but Jimmy tells her he doesn't think it's either of those. A brief moment of her crying in the hospital waiting room is shown but the reason still isn't revealed.
The next shift, the house is on lockdown from a tornado warning. Jimmy asks Chili if they can be friends to which she agrees, but the next second, she lashes out and tells him he isn't worth it and that it's unbelievable he would break up with her just because Casey told him to. During a call later that day, Chili mistakenly injects a seizing victim with morphine instead of valium, which causes the girl to stop breathing altogether instead of stopping seizing. She zones out after this and Sylvie takes over, properly injecting the patient and therefore saving her life. Chili says it's no big deal. At the hospital, she lies to the attending when she says the reason the woman has morphine in her system is because she accidentally knocked over a bottle, causing it to break. Sylvie tries to talk to her about this later but she brushes her aside and is making plans to go out. Wary and finally tired of her behavior, Sylvie reports her actions and the syringe accident to Chief Boden. After Alissa's death, Chili starts drinking to cope and Borelli and Brett both witness her mood swings. While at Molly's, Dawson is talking to Antonio who tells her that Chili's sister Alissa was found dead in her apartment a week ago. Boden asks her about this and she says she is fine, he gives her the second strike for the syringe incident though. She then apologizes to Dawson and Sylvie for acting rudely towards them and they accept. However, they see her drinking the next night and are disappointed. She starts up again and during a call, Sylvie ignores a direct call from Chili, who then tells Boden she wants Sylvie gone. Sylvie also finds out that Chili was asked to leave from the last house because of her problem. Boden gets angry hearing this and asks her to work things out or she'll be gone from 51 too. They both work things out at a later case where she apologizes to Sylvie for nearly replacing her. She pushes them away by repeatedly brushing them off. Things go downhill again when Chili receives a package at her day off containing all of Alyssa's belongings and she breaks down again. She then starts to make a habit of taking small breaks to drink and then come back and spray some breath spray and chew gum so the people don't notice. However, Severide notices her constant breaks and tries to talk to her but she ignores him and Sylvie tries to look past her issues. However, Severide eventually catches her out and tells her to talk to Boden or he will. She goes to see him and tells him she needs help and is willing to take time off to go to counselling but he fires her instead. He then tells her to ask for help and she says she just did and they did nothing. She goes to her locker and the whole of 51 follow, trying to talk to her. She says they aren't her family and leaves, including leaving her photos with them behind. Herrmann gets one of the photos and frames it and takes it to her apartment. He tells her through the door that she can always come to him and leaves the picture behind.
Chili calls someone and tells them she needs help. It's revealed it was Severide, who takes her to counselling and is glad she called. She tells him she'll call them and apologize. She thanks him and she goes to rehab. At Severide's urging she enters an alcohol rehabilitation program to get help.
In "Bad For The Soul", she was mentioned when Sylvie asks Jimmy if she's responded to their calls, which she hasn't.

Firefighter / Chauffeur Brian "Otis" Zvonecek (season 1: recurring; season 2– ) is a firefighter in Truck 81 and was the most junior at 51 until Peter Mills' arrival. Nicknamed after the eponymous elevator company as he is frequently assigned to elevator or ladder duty, Otis had just recently finished his candidacy before Mills joined the truck company. He is eager to move up the ranks within the firehouse but often feels overlooked and unappreciated by the rest of his truck company. The other more senior firefighters would pull rank, including Lieutenant Casey, and assign him to do undesirable menial jobs around the firehouse or pull pranks on him. This led him to consider transferring to another firehouse, but he ultimately decided to stay with Truck 81 after Severide pranks him into believing that the rest of the crew had placed a bet on how long he'd last at 51. In season 2 Otis begins a relationship with Katie, Kelly's half-sister. During "You Will Hurt Him", the house finally gets to meet Severide's half-sister Katie Nolan when she brings them lunch. Brian shows interest but Severide is very protective of his sister. She goes by the house again to bring them more food and tells Otis he should be home for dinner as Katie is coming over. The both bond over a game of Catan and end up kissing. Otis, then, asks Severide for his blessing as he wants to take Katie on a date. After messing up with him a little he eventually says yes. The two begin dating. Until she is kidnapped. Otis feels guilty he wasn't with her at the time it happened but Severide calms him and assures him it is not his fault. After she is found and taken to the hospital Katie makes the decision to move to Colorado. At the end of "Rhymes With Shout", Otis and Severide arrive to an empty and looted apartment. Shay gave Devon a key and she stole all of their valuables, including Otis' collection piece (that later turns out to be completely worthless and fake). After this event Brian decides to leave the apartment and find his own space. Meanwhile, Cruz comes up to him and tells him that, since they are both "roommateless", they should find a place together. It was revealed to be Shay's runaway ex Devin absconded with their money and possessions. Later in the season, he and Cruz decide to room together. As the most tech-savvy of the crew, he becomes something of a cult figure amongst other firefighters due to his podcast, called "Good to be a goat" after Truck 81's mascot, about life as a firefighter. He often comes up with ideas and solutions for everything, much to his colleagues' amusement and derision. As of season 4, he was "promoted" to chauffeur as Cruz transferred to Squad 3. In "Joyriding", the day of the Union presidency vote, Mouch and his opponent Greg Sullivan have an all-important live debate on Otis' podcast. The debate is a disaster, Mouch opts to keep his integrity and to not use personal information on Sullivan that could ruin his run, thus losing the presidency. In "Just Drive the Truck", when Cruz is suspended from driving, for three months, pending investigation following the crash of Truck Co. 81 with Truck 66 from Welch's antagonistic Firehouse 105. Casey puts Otis as driver. In "The Nuclear Option", Otis' nephews come to visit the Firehouse and he is excited to take them on a ride while driving the Truck. Cruz' suspension is lifted and he is now back on the driver seat. However, on the last episode of the season Scott is kicked out of Squad 3 leaving a void. It's revealed that Cruz passed his squad certification and is now on squad. Otis is now the Truck driver. Dawson begins as a candidate and Otis tries to prank her the same way the guys did to him when he first started, but since she was already at the house she is aware of the pranks and manages to steer clear of them. Ever since Cruz broke up with Sylvie, Otis has shown interest in her. After the break up Sylvie comes up to him to return a book, after that conversation Otis goes to Casey and says he might be in love with her. Casey tells him that it is crazy to even look at his best-friend's ex the day after they broke up. During the entire season, Otis makes advances on Sylvie trying to go on a date with her. In "On The Warpath", he asks Sylvie if she has plans for the following night as Phantasm is showing at the Music Box. She has no idea what Phantasm is and the two are interrupted by Jimmy bringing Sylvie coffee. Brett gets herself into trouble, so Jimmy gives her a ride home. As they are both leaving Otis tells Cruz that Phantasm was never going to happen. He stated his intentions, he even changed his looks but he finally realizes nothing would ever happen between him and Sylvie.
In season 1, Otis, Herrmann and Dawson buy a bar which they call Molly's. The bar is also seen on Chicago P.D. as it is popular with firefighters and cops. Otis is shown to be the more business-minded one and often had to remind Herrmann about paperwork for inspections and bills.
Otis is unabashedly proud of his Russian heritage and frequently speaks of his parents and his grandmother ("Baba"), although actor Yuri Sardarov is actually of Georgian and Armenian heritage. It is implied that Otis was either born in the United States or emigrated as a young child. He comes from a large family and every season has seen him introduce or speak of various relatives, with his grandmother even moving in and sleeping in his bunk bed. His father died of leukemia. Cruz was initially furious with Otis for only telling him the day "Baba", who spoke no English, shows up at their apartment but relents after Otis explains his reasons. In season 1 there was a running gag where he would tell his colleagues in any joint venture that he had "a cousin" who could come and help. For example, he gets his Russian cousin Zoya a job as a waitress at Molly's but incurs the wrath of business partners Herrmann and Dawson after they find out Zoya barely spoke any English.
In "I Will Be Walking", while changing in the locker room Cruz asks him what happened to his back as he has a bruise the size of a bread basket. Otis gets suspicious about some bruises that appear on his back and hip. He asks Sylvie's opinion, who tells him to get it checked out by a doctor which he doesn't want to do fearing it might be something serious. He also asks Sylvie to keep it a secret from the house. In the episode "Kind of a Crazy Idea", eventually he decides to get it checked out by Dr. Halstead from Chicago Med. However, he still doesn't want to know the diagnosis and lies to Sylvie about having his blood results back and everything being ok. Later on Sylvie finds out the truth and asks Cruz for help. Cruz enlists the help of Otis' grandmother, who after a visit to the Firehouse convinces him to get the tests done. Otis is diagnosed with immune thrombocytopenic purpura and went on medical leave. He returns to the firehouse, and he meets his temporary replacement and is convinced by Herrmann that Connie was trying to replace him permanently. Otis then takes Connie to the theater and she tells him that he always has a place at 51. Otis, along with other Members Of Chicago Fire Department Truck Company 81 are concerned about Borelli's Behavior following his brother's death. Other storylines include him still working at Molly's and still working as a member on truck.
In season 6, he goes into a relationship with Lily, whom he met when he visited a bar that was in the stages of closing, in what would become Molly's North.
In "The Chance to Forgive", while performing an evacuation on a house fire, he was shot in the neck and severely wounded. In a twist, the guns were inside the house and the ammunition was being fired due to the fire. He was eventually taken to Chicago Med, where Dr. Ethan Choi tells everyone that the bullet is lodged near his spinal cord and operating could cause serious problems. The owner of the guns won't be charged, since he owned them all legally and didn't intentionally hurt Otis. At the end, Otis got through his surgery in one piece. Choi sticks his head into the room and realizes that Otis can't feel anything in his toes.
Otis returns to active duty in "The Strongest Among Us", having fully recovered from his injuries, and butts heads with Kidd over who gets to drive Truck 81.

|Department||Chicago Fire Department
- Portrayed by Joe Minoso
Firefighter/Chauffeur Joe Cruz (season 2 – present; recurring season 1) is the designated chauffeur for Truck 81. In season 3, he tries out for squad and has transferred to Squad 3 by the season 4 premiere.
Having grown up in the gangster-infested neighborhoods of Humboldt Park where he was regularly "lulled to sleep by gunfire", many of his peers were gangsters and he is constantly trying to keep his younger brother Leon out of the local gang. He is haunted by a decision that he made on the job related to his brother that later affects his own safety and the safety of his fellow firemen, forcing Casey to discipline him. Indeed, during a fire, he let Flaco, the boss of his brother's gang, die in which Casey threatened to go to the police about Flaco if Cruz did not resign. Casey later reconsidered his decision. Leon was after able to leave the gang and even went to university. When Leon realizes what his older brother had done, he vows not to let Joe down and enrolls at a local community college. Sergeant Voight seeks Cruz's permission to send Leon back into the gang, albeit undercover, after a little girl was killed in a drive-by shooting in his neighborhood, so that the Chicago PD can shut down the gang once and for all. The takedown is successful but came at a cost: Leon took a bullet and eventually left Chicago for his own safety and start a new life away from gang influence. Leon is currently living in Florida.
Cruz is generally well-liked by his co-workers and is often seen cracking jokes and exchanging banter with the rest of the crew. He and Otis often bicker with one another in the lounge during down-time over the most trivial matters. They later share an apartment together, thus referring to their arrangement as "Crotis" (a portmanteau of Cruz and Otis).
At the end of season 1 into a portion of season 2 Joe begins a relationship with Zoya, Otis's Russian immigrant cousin and decides he wants to marry her to get her to stay but she feels that is not right so she leaves. In season 3, he begins dating the new paramedic, Sylvie Brett.
Seeing the success of the bar Molly's owned by Dawson, Herrmann and Otis, Cruz decided alongside with Mouch to be part of the project. Cruz came out with the idea of making "Molly's II" a truck. This project convinced Herrmann and was accepted. Finding a truck was difficult but Newhouse found one at the condition to be a 20% associate.
Joe was the driver of Truck 81 and received a suspension from Deputy District Chief Joel Tiberg when 81 got involved in a T-bone collision with Truck 66 from Firehouse 105 in Austin since they were both en route to the same structure fire. The collision resulted in Mouch sustaining a major eye laceration, 2 guys from Truck 66 having a broken arm for one and a broken leg for the other, and the driver Jason Molina was knocked unconscious. At first he was accused of blowing a red light because he forgot the color of the traffic light and because he blew another red light 30 seconds before the accident. But when Molina woke up, he confessed that his Lieutenant, Tommy Welch, ordered him to beat Truck 81 so they could take command of operations at the scene. He was cleared of the accusation and since Molina woke up, he was not charged with manslaughter. He still got a 3 months suspension from driving the truck and was temporarily replaced by Otis, who was next in line to drive 81. However, Chief Boden managed to reduce his suspension.
Cruz is a dance instructor and teaches zumba when off-duty, a fact which he keeps secret about until Brett coincidentally turns up at his zumba class as she lived nearby. He asks her to keep it a secret as he did not want to be ridiculed by his colleagues at 51. A running gag in the show is Cruz's inability to cook; he tries to fill in as the firehouse cook after Mills is promoted from Candidate status but his cooking is often met with ridicule from the rest of the firehouse. He currently works as a bouncer at a bar. Since Cruz regularly went to talk to her about the class, Casey became suspicious and went to talk to Brett about romantic relationships inside the firehouse. To clear the misunderstanding, she revealed to him that Cruz is actually her instructor. Casey talked about to Dawson who told Herrmann and so on until the whole firehouse knows about it. In "Chopper", the guys from Truck 81 and Squad 3 came to assist one of his classes. In "Spartacus", after Scott Rice is given the boot, Chief Boden announces that Cruz received his squad certification just before shift started and he is subsequently given Rice's spot just as a call comes in. At first Otis is pissed Cruz did not tell him first due to the recent tensions between Truck and Squad but later congratulates him at Molly's.
In "Hiding Not Seeking", he grows increasingly concerned about Brett after she volunteers to go undercover to one of the bombing suspect's house. After it was successful, he begins to take it out on her.
In "The Chance to Forgive", he became too personal when a call to a house fire goes awry and Otis is severely wounded. Cruz yells at the guy as he leaves the hospital in shame, and vows revenge after Otis finally wakes up. Later in the hospital church, the father of the gun owner thanks Cruz for saving his life, and says he didn't know his son had all those guns. When the call of another house fire of the same address as the first encounter, the gun owner tries to kill himself due to his guilt over the events that played out. Cruz goes in and gets him. Moved by watching the kid nearly die, Cruz encourages him to stay alive.
Randy "Mouch" McHollandEdit
|First appearance||Pilot (episode 1.01)|
|Portrayed by||Christian Stolte|
|Full name||Randall McHolland|
|Department||Chicago Fire Department
- Portrayed by Christian Stolte
Firefighter Randy "Mouch" McHolland (season 2 – present; recurring season 1) is one of the veteran firefighters of Truck 81. As the longest-serving member of Truck 81, he, along with Herrmann, is often seen as the ringleaders and respected by the rest of the crew as such. Mouch serves as union representative for the members of the station when they face disciplinary action or a lawsuit and is knowledgeable in the legalities and political side of the fire department. He has a part-time job as a security guard. Instead of "McHolland", he has "Mouch" written on the back of his turnout coat. With the help of Herrmann, he joins the race for fire union president but loses his chance to win due to his refusal to play dirty. When Firehouse 51 is about to be shut down, Mouch is the one who rallies the union's executive committee to stand up to Gail McLeod.
Infrequently referred to as "Randy", Mouch gained his peculiar nickname due to the fact that he can almost always be found on the couch watching television when not on a call ("half man, half couch"). He offends Boden's secretary Connie, who has the couch moved to the space outside Boden's office. He spends much of the episode distressing over the loss of "his" couch before succumbing to Herrmann's advice to apologize to Connie. She finally returns the couch to the lounge after Mouch apologizes twice.
Mouch was in a long distance relationship with a Japanese woman named Mari. In season 1, Mouch was taking Japanese lessons. She is from Japan and comes to visit Mouch in A Hell of a Ride. She leaves in A Problem House. Mouch says he will try to visit her, but this never happens and they end up breaking up. Later Shay sets him up with a "Golden Oldies" dating profile and he acquires a blind date. His lack of social skills around women hinders him and his colleagues have had to "coach" him on the idiosyncrasies of taking women out on dates. He meets Chicago PD Sergeant Trudy Platt (Amy Morton), who also appears in Chicago P.D., by accident at Chief Boden's wedding reception and they have been dating ever since. As such, Mouch has appeared on Chicago P.D., usually to visit Platt. In season 4, he finally finds the courage to propose to Platt but it goes down the drain and they have to part ways after he is called to an emergency. Platt eventually proposes to spare him the embarrassment and they agree to get married. They marry in an intimate ceremony at Molly's, in the presence of Mouch's co-workers from 51 and Platt's co-workers from the 21st District. They went to the Wisconsin Dells for their honeymoon.
In a Chicago PD episode "All Cylinders Firing", after Platt was a victim of brutal assault, Mouch goes to Chicago Med to see her and while there, was questioned by Voight and Lindsay. He took offense when he was labeled a suspect by them. But he affirms his innocence and demanded to know the truth about what had happened.
Towards the end of season 5, Mouch considers retiring from the fire department.
In the Season 5 Finale, Mouch, While trapped inside of a burning factory, seems to be having a heart attack. In the season 6 premiere, luckily, he is back at 51 with all members returning to normal lives. He delivers a moving speech about how close he came to "walking off of this job". he didn't mean that his heart stopped. he had almost gave up on the second greatest thing in his life because he was feeling a little "run down". as he says "while I was lying down on the ground in that burning factory, the one thing I thought about was It wasn't Enough". He treasures the time that he has with his brothers and sisters at 51. He hopes he will never have to look down that dark tunnel ever again. He realizes he has not had enough time with Trudy or his coworkers at 51. He signs the whole firehouse second shift up for a Firefighter's muster. he believes that his friends at 51 have been there for him day in and day out no matter what. He is married to Trudy Platt from Chicago PD.

Firefighter Candidate Jimmy Borelli is the newest Candidate at Firehouse 51 introduced in the season 4 premiere. He comes from a family of firefighters "who drink testosterone for breakfast". His older brother Danny (Andy Ahrens), a firefighter at Engine 67, pranks him by dousing him with beer, dumping him in the trunk of his car wrapped up with duct tape and drops him off at 51 in front of a bemused Chief Boden, Lieutenant Casey and most of Truck 81. An unimpressed Chief Boden tells Borelli to go home and never come back to 51 but Jimmy returns to apologize and promises to earn his place. True to his word, he shows himself to be hardworking and dedicated, earning the acceptance of his truck company and the trust of his lieutenant. Casey commented that Borelli was one of the best Candidates he has had on 81 in recent years. Danny tries to get Jimmy into the same firehouse and is rebuffed by his younger brother. He later explained that he had promised their dying mother that he would protect Jimmy, hence his actions, but stops pursuing the matter after Jimmy explains that he wants to stay at 51 due to the "family" atmosphere. Like Mills before him, Borelli was assigned to kitchen duty and menial tasks and occasionally subjected to pranks and good-natured ribbing from the more senior firefighters. For example, Gabby Dawson's brother Detective Antonio Dawson talks him into representing 51 at the "Battle of the Badges" boxing match organized by Mouch but his co-workers at 51 intentionally leave out the fact that the detective was a seasoned amateur boxer.
Borelli was attracted to Paramedic in Charge Jessica "Chili" Chilton and they begin seeing each other until both Lieutenant Casey and Chief Patterson catch them making out and give Borelli a stern warning about fraternization rules. Chili tries to brush it off but Borelli respected Casey and asks Chili if they could "cool it", to which she angrily accuses him of not being serious in their relationship. Their relationship is further strained after Chili spirals out of control when she starts drinking to cope with the death of her sister and repeatedly refuses help from him or Sylvie Brett. Chili leaves 51 to enter rehab and Brett becomes the new PIC. Borelli is transferred to Ambulance 61 as his spot as a Candidate at 51 was under threat due to budget cuts and reshuffling of manpower.
In "Where the Collapse Started", Danny comes over and asks Jimmy for some help with a bar deal. But after Jimmy finds out what's really going on, he refuses. Danny becomes angry and leaves. Later, the house gets a call for a structure collapse where Truck 70 and Engine 67, Danny's company, are already on scene. Danny goes into the building along with Truck 81 and Squad 3 and ignores Jimmy. After the firefighters find and evacuate victims with the building crumbling around them, Severide reports to Chief Boden and he gives the order to evacuate. But Danny believes he heard someone still call out and asks Boden to bring the victim out so he is given one minute. But the roof collapses moments later and Jimmy rushes in. Upon arrival, Jimmy requests Squad assistance for extrication since Danny is pinned but Boden is hesitant. Boden himself then goes inside and pulls Jimmy back just as more debris falls on Danny, killing him. Outside, firefighters, paramedics, and cops line up to form an aisle leading to Ambulance 61 and salute as some firefighters bring out Danny's body and Jimmy leads the way to the ambo. Jimmy then takes some time off after this incident. The next evening, Jimmy shows up at Casey/Severide's apartment and tells Severide that he believes Boden made a mistake by giving Danny one minute that he didn't have. He then storms off after Severide tells him to cool off. In "The Hose or the Animal", he files an official grievance against Boden.
Borelli returned to Truck 81 in season 5 but the character was written out in the second episode after being injured on the job. He suffered serious injuries to his hand, face, neck and left eye in an explosion. It is implied, based on Dr. Halstead's prognosis, that his career as a firefighter is over. In the third episode, Boden mentions that Borelli's family had him transferred to a long-term care facility.

Stella Kidd is the newest transfer at Truck 81. She had known Gabby Dawson from the academy and transferred from a firehouse in Auburn. When news of her transfer first reached 51 it was met with much derision as Borelli, by then a popular figure with the crew of 81, had left his candidate position to join Brett at Ambulance 61 due to manpower changes. Like Dawson she quickly shows that she is able to hold her own in a male-dominated firehouse. Her first appearance was "Bad For the Soul". When Kidd first arrives at the House Gabby acts as they have problems, just kidding around as it is revealed they are good old friends. When asked she said that the only thing she heard about Firehouse 51 was that they all live together. She tells the House that she is recently divorced and is enjoying the single life. Kidd says she goes out whenever she wants, eats at nice restaurants and whenever she's lonely she sleeps with her ex, something that apparently he is alright with. Kidd quickly proves to be a worthy firefighter and a great asset to the House.
While writing her name on her new locker, Kidd asks Gabby whose locker it was before hers as it smells like cologne. Gabby tells her that it used to belong to one of Severide's old friends, Scott Rice, which didn't end well. When Gabby says Severide's name Kidd acts suspiciously shy and "blushy", but they are interrupted by Severide, cutting the conversation in half. Severide then apologizes for "the most embarrassing night of his career" since he didn't know she was married and showed up with a six-pack at her back door. Her husband went crazy and actually wanted to press charges against Severide. The awkward situation is put behind them and everything seems ok. Grant shows up at the firehouse looking for Stella. Saying he misses her and feels so lonely it's like he is going to die. She then goes to the Turn-Out Gear room with him to administer him a B-12 shot.
It is implied that she and Severide had known each other at some point prior to her transfer. They begin a "no strings attached" relationship but it hits a hurdle when her ex Grant shows up. Stella shares with Severide that Grant is using again and that she is worried about him. During the last episode Grant shows up at Molly's, Stella and Severide walk in together causing Grant to fight with Kidd once again. A while later, Grant texts Kidd. She tries to call him back and realizes he is on something. Worried that something might have happened to him, she locates his phone. The team leaves the House to find an overdosing Grant. At the hospital Stella tells him that he needs help to get clean. Grant insists she is all he needs. Nonetheless, Stella is done and Grant shouts at her to leave. Kidd leaves, worried. Dr Charles calms her down telling her that rock bottom always looks ugly but they will do their part to help him. His behavior becomes erratic and escalates but she tries to deny that there was a problem, even after he attempted to assault Severide and overdosed. The final straw came when he escaped from the hospital to sneaked into her apartment with the intent of hurting Severide, but does not go through with it. She finally makes the decision to force him to go to rehab by severing all ties with him.
On "What Happened to Courtney", Herrmann is looking for entertainment for his daughter's Annabelle 8th birthday party as the guy he contracted is double-booked. Kidd tells him she knows a guy, her ex-husband is trying to start over and just needs a chance, he will also do it for free. Herrmann accepts the offer. Grant takes the gig with one condition, Kidd has to give him another chance. The reason why Grant's band previously broke up was because the drummer got caught sleeping with the bass player's fiancée. Kidd says she still cares for him but he has to show her that he is growing up and changing in order for her to pursue a relationship with him, again. However, when the party time comes he never shows up leaving Stella with the only choice of coming up with a last-minute entertainment plan, Molly's Jr. Later on, Stella meets Grant at his place, where he is playing music. Stella gives him the house key and tells him that it's over as he missed the party after she backed him up to people she didn't want to disappoint. Grant tells her the band is getting back together.
Mouch invites Stella for his wedding, she will stay at a table with Trudy's friends and Severide. She tells Severide to bring his "A-game". His answer is that that's all he's got, to which Kidd asks if breaking and entering it's his "A-game". That's when the House realizes there's an awkward story between the two. During the after wedding party at Molly's the guys are all together and ask for the real story. Stella tells them that one night after a tactical training course at the academy Severide showed up with a six-pack, after using the key under the mat to get into the house. She convinced Grant to not call the police. The following day Severide tells her he owes her a big favor.
Herrmann and Kidd get on a discussion about who is the best manager. Stella states that she ran the best pub in Milwaukee for 2 and a half years. Gabby then proposes they settle things by doing the "Bar Olympics": 2 contestants, 10 events, winner takes all. Kidd wins. However, instead of the money she wants to help them manage Molly's. One of the changes she introduces to the bar is the artisan ice cubes, the giant perfectly clear ice cubes, that require a special machine to make them, so they can charge more per drink and sell more cocktails than beer. She finally convinces them to buy the machine. However, later on the House is called to a fire at Molly's that apparently started because of said machine. Stella feels awful about what happened so she decides to fix the damage herself. Stella and Severide flirt throughout the season. He shows up at Molly's to help her, as it is clear she can't do it alone. Kidd tells Severide she doesn't understand why when she was married he broke into her house with flowers and champagne but when she is finally single he keeps a distance. The two kiss and start a romance. When she was leaving the house and getting into her car, Kidd notices a paper on her car. It's an invitation from Grant for his band's show.

EMT Emily Foster was introduced as the new paramedic at Firehouse 51, replacing Gabriella Dawson after she stays in Puerto Rico. Initially, she and Brett get off to a rough start due to Brett still being hurt by Gabby leaving. But, Foster quickly gets settled into the firehouse and reveals to Brett she was a former medical student, but due to a unknown cause in her personal life, she cheated on her SATs and was promptly dismissed. However, her more advanced medical training allows her to accurately diagnose patients afflictions, but she has overstepped her boundaries at times, as she is a paramedic, not a doctor. Later, she reveals to be bisexual after Brett tries to defend her after she was stood up on a date, only to learn her date was with a woman. In "You Choose", she goes on a date with Dr. Jim Shaw, the doctor she suspected and later cleared, of overdosing a patient. In "Make This Right", she has a one night stand with him and tries to break it off. At the end, he shows up in the Molly's as her and whispers to her that he will back down. In "The Plunge", his continued harassments takes a toll on her job when she got called to Lakeshore Hospital where an anonymous complaint, implied to be Dr. Shaw, had been filed against both Foster and Sylvie Brett, that could potentially revoke their paramedic license. Foster finally decided to come forward about the harassment to Chief Boden. Then, she decided to confront Shaw herself, and with Brett backing her up. In the middle of Lakeshore Hospital and with a half-dozen other women watching, Foster told him to “come at me with all you got.” So Shaw did literally, following her out into the parking lot—where Brett had called in Boden and the rest of Firehouse 51.

EMT Peter Mills (season 1–3) was introduced as the Firefighter Candidate at Truck 81. Following in the footsteps of his father, Peter aspires to join the Rescue Squad. His father served with Chief Boden and Lieutenant Severide's father Benny. Just minutes after arriving at the firehouse, he quickly finds himself caught in the middle of a spat between the firehouse's two Lieutenants, who have been at odds with one another since Darden's death a month earlier. As the new Candidate of Truck 81, he was pranked by his more senior counterparts and referred to by his whole name instead of his last name as per custom. At the end of season 1, he picks up an application for the Chicago Police Department because he does not get promoted to squad and to avoid Chief Boden. However, Mills later gets rewarded with a promotion to Squad 3. After badly injuring his leg in the season two finale Mills is put off work for six weeks but returns after four weeks in the season three premiere. After revealing to Lt. Severide that he gets dizzy whenever he isn't up right, Severide tells him to see a doctor. The doctor tells him that he can no longer be a firefighter. This all happens after Dawson is named to be a candidate on Truck 81 so because Mills has EMT training, he applies to replace Dawson as PIC and gets the job and now works with Paramedic Sylvie Brett. In season 3, he stated his desire to return to Squad 3, only to find that Severide had already filled the vacancy left by Newhouse. In late season 2, he asks Newhouse, one of Severide's men in Squad 3 who moonlights as a private investigator, to track down his father's side of the family as he wanted to know why his mother had forbidden him to talk about his paternal relatives or contact them all these years.
Mills begins dating Gabriela Dawson in secret, later breaking up with her because she keeps the knowledge of an affair between his mother and Chief Boden from him. He tells Dawson that he would be willing to start over with her if she can tell him for sure that she does not have feelings for Casey, but she cannot, and the two officially end their relationship. He later dates Isabella, a friend of Dawson's, and their relationship takes various turns: first they meet and she takes him to a formal event with Senator Wheeler and reveals her future ambitions; they feud because he felt used as his feelings of insecurity took over. Later they get over the feud and grow closer, Finally when the firehouse is in severe danger of closing he asks her for help to save 51 and they work together.

After Mills is promoted from Candidate status, the men have a hard time finding a replacement, with Otis and Cruz both trying but failing miserably.
In season 3, Mills' family is notified that his paternal grandfather has left them a restaurant in Wilmington, North Carolina.

Paramedic Leslie Shay (seasons 1–2) was Gabby Dawson's partner at Ambulance 61 and the designated driver. An experienced paramedic, she was well-liked by the mostly male crew of 51 and was frequently seen joking and horseplaying with them in the lounge during downtime. She and Kelly Severide shared an apartment as roommates and were best friends. Shay was openly gay, often cracking self-deprecating jokes about it, and was entangled in a relationship with her ex-lover Clarice who was most recently married to and impregnated by a man. She was fiercely loyal to her friends, particularly to Kelly, for whom she has risked her job for several times. Towards the end of season 1 and the beginning of season 2 she tries to have a baby through artificial insemination with Kelly but the process fails. She was also close with Dawson, but a rift comes between them when Dawson fails to be there for her during her downward spiral of guilt over a man's suicide. She then gets mixed up with a girl she met, Devon, who she really liked, but that all ended when Devon robbed Shay and her roommates, Severide and Otis. Shay disappears and Severide tries to look for her. He asks for Dawson's help and when Dawson finds her they rekindle their friendship and Shay goes back to Firehouse 51. An accident in the cliffhanger season finale of season two leaves Shay critically injured in the explosion of a building and she dies in the third-season premiere "Always". Her death affected the entire firehouse as she was popular with everyone and well-liked by the mostly-male crew. The subsequent investigation and Severide's own observations reveal that Shay had been murdered. Chicago PD detectives later linked the fire with a string of unsolved arson cases dating back several decades. The investigation proved that the arsonist and murderer of Shay was Trenton Lamont under the aliases of Adrian Gish and Ross Mcgowan. Shay was avenged for good when Lamont was later shot and killed by Chicago PD detective Antonio Dawson.

Firefighters and paramedicsEdit
- Jose Vargas (Mo Gallini) is a former firefighter at 51. A sixteen-year veteran of the CFD, Vargas recently transferred from Truck 81 in the episode "Professional Courtesy" to Squad 3. Initially, Severide questions if his motivation was due to monetary benefits and a potential promotion but Vargas proves to be one of his most reliable men. He is forced to retire after he suffered serious injuries to his lungs in a warehouse fire and considers suicide by jumping from his apartment building rooftop, but Severide and Casey talk him out of it. In the beginning of season 3, he appears in a flashback on Shay's first day at Firehouse 51.
- Harold Capp (Randy Flagler) is a member of Squad 3. He is usually one of the less vocal firefighters at 51 and is particularly loyal to Severide. He and Tony are the only remaining men who have been with Severide in Squad 3 since the first season.
- Tony (Anthony Ferraris) is a member of Squad 3. Although his turnout coat has his last name, he is always addressed as "Tony" by Severide. Ferraris himself is a Chicago Fire Department firefighter and is one of several CFD current and retired firefighters involved in the show.
- Kevin Hadley (William Smillie) is a former member of Squad 3, he was transferred out of Squad 3 to another house because of an inappropriate prank on Peter Mills. In season 2 he targets Firehouse 51 and personally targets Severide for revenge with arson attacks and burns himself when pouring gas on himself and standing on top of an accelerant, leaving him badly scarred and in constant pain. He is currently in prison. He appears in a flashback on Shay's first day at Firehouse 51 in the season 3 premiere.
- Allen Chout (Alex Weisman) is a paramedic who was introduced in the season 2 episode "Rhymes with Shout", the episode title being a reference to how his last name is pronounced. He has also appeared on Chicago Med.
- Rick Newhouse (Edwin Hodge) transfers from the fictional Squad 6 based in South Side in the season 2 episode "One More Shot" to fill the empty spot left behind in Squad 3 after Clarke's promotion and subsequent transfer. His experience and charismatic personality quickly wins over Severide and the rest of the men, although Herrmann initially antagonized him as he had yet to come to terms with the recent suicide of Candidate Rebecca Jones. When off duty, he moonlights as a skiptracer and has been seen entertaining his coworkers with stories of his "clientele". Mills looks up to him as an older brother figure. He hails from the crime-ridden Chicago area of Roseland and, despite getting out, still goes back to visit family. He is a single father with an elementary school-age daughter Naomi. In season 3, he leaves Chicago to visit family in Miami and Scott Rice takes over his spot on Squad 3 on a temporary basis. Whether or not Newhouse will return remains ambiguous.
- Pouch the dog: Peter is given a dog by a child from a family who could not take care of it. Hermann, Chief Boden, and Mouch decide against it. Eventually, the three agree after Hermann suggests the three should rethink the dog. She is given a name and adopted by the team. Pouch's name was decided by Hermann, who suggests she should be named after Mouch, which is half man, half couch, to Pouch: half pooch, half couch. Mouch was initially against them adopting Pouch because of a bad experience he had with the dog at his former firehouse but comes to enjoy Pouch's company. The two are often seen on the couch together. In the episode "The Last One for Mom", Pouch bonds with Detective Holloway's son JJ, who Kelly is watching over while she is working an undercover assignment. After Holloway is killed, the team decides to let Pouch go with JJ when he leaves the firehouse with his aunt.
- Firefighter Candidate Rebecca Jones (Daisy Betts) was a Candidate assigned to Truck 81 and the only daughter of Deputy District Chief Lionel Jones. She and Gabby Dawson were the only females in their cohort at the fire academy. Dawson catches her cheating in the theory test but decides not to say anything after Jones revealed the real reason why she wanted to become a firefighter. The men of Truck 81 are unsettled upon finding out that she was their new candidate. She turns against Dawson after being told to clean the toilets by Herrmann, backed up by Lieutenant Casey, both of whom already had reputations for being hard on Candidates, as she thought that Casey and Dawson were colluding against her.
- Lieutenant Jeff Clarke (Jeff Hephner) is a former member of Squad 3. After his firehouse is closed, he is transferred to Firehouse 51, Squad 3. Initially, he was not liked by the rest of the crew as he was extremely private and preferred to read newspapers at the squad's table rather than socialize with them in the lounge. His arrival at 51 coincided with McLeod's efforts to find reasons to close Firehouse 51 down and he was falsely accused of being McLeod's mole. When the rest of the firehouse realizes that he had actually turned McLeod down, they befriend him and helped him through his marital problems. He was also revealed to be a former Marine and Iraq veteran. His wife Lisa had cheated on him while he was on his final tour and were estranged when the character is first introduced. They reconnect after she asks for his forgiveness and he and the crew were nearly killed by a burning propane tanker on a call. Lisa's ex-lover Hayes turned out to be a loanshark who continuously harasses them to the point where Clarke was prepared to kill the man with his military-issue sniper rifle. When Hayes is found dead, Clarke becomes the prime suspect and tries to protect Lisa upon finding out that she had been involved. The detective in charge of his case Jay Halstead sympathizes with him (it is revealed in Chicago P.D. that Jay was also a military veteran) after Clarke explains that he had to protect Lisa as she was the only one who was there for him when he returned from his tour of duty suffering from PTSD. He transferred out of 51 after being promoted to lieutenant and is now the commander of Truck 25. His last appearance was in the episode "A Heavy Weight", when he drops by 51 to check up on his friends after Rebecca Jones' suicide. After his promotion he hurts himself on the job and returns to Med School and is now a Resident at Chicago Medical Center, thus becoming a recurring character on Chicago Med. He also reveals that he and Lisa eventually divorced.
- Lieutenant Spellman (John Hoogenakker) is introduced as a transfer to Firehouse 51, along with Clarke, after city budget cuts force downsizing in the CFD. He is later revealed to be the snitch to Gail McLeod and is "transferred" out of 51. Mills realizes that he was McLeod's "spy" and Spellman is quickly transferred out after the entire crew, Lieutenants Casey and Severide and Chief Boden included, stage a "rebellion" by handing him pink transfer forms and taping his locker with pink forms.
- Chaplain Orlovsky (Gordon Clapp) is a CFD chaplain and long-time colleague of Boden. There was some tension between him and Boden due to unresolved issues from the past, but they put it behind them after Orlovsky explains what happened. He runs a boys' hockey team, which Herrmann's son Luke is part of. Boden would send his firefighters to the chaplain for counselling, especially after a traumatic experience.
- Paramedic in Charge Allison Rafferty (Christine Evangelista) joins Ambulance 61 as Leslie Shay's new partner and Dawson's replacement after the latter begins training at the fire academy. At first Rafferty seems distant toward Shay and when Shay later confronts her, she tells her that her previous partner at 24 was a lesbian and used to make "graphic" phone calls to her girlfriend that made Rafferty uncomfortable. In her second episode appearance, it is revealed she was a resident doctor at Chicago Med but dropped out when her fiancé developed Hodgkin's lymphoma; he died six months later. She is suspended for treating a patient that refused treatment, and Dawson regains her spot on Ambulance 61.
- Erik McAuley (David Pasquesi) is a paramedic who has appeared in several episodes on relief duty. He is known for his sarcasm and pessimism and was described by the crew at 51 as "the worst Mr. Doom and Gloom" and "Eeyore".
- Scott Rice (Warren Christie) is a former firefighter with 114 who rejoins the CFD and fills in the empty spot in Squad 3 vacated by Mills, who was out with an injury. He is widowed with a young son named Logan. Severide had recommended him and his arrival was met with suspicion, particularly by Otis. According to Otis, there were rumors going around about Rice shirking his duty or losing his concentration at critical moments.
- Battalion Chief Dallas Patterson (Brian J. White) was assigned by Chief Riddle to oversee Squad 3 during Severide's temporary demotion in the season 4 premiere. Severide tries to hide the fact that he resents Patterson, who attempts to win over the men of Squad 3 by taking the tab or buying pizza for them. He is given the promotion from Captain to Chief during Boden's legal troubles, much to everyone's dismay. It is later revealed that Patterson had actually been waiting for an opportunity to trap the much despised Chief Riddle and force him into retirement.
- Firefighter Candidate Darren Ritter (Daniel Kyri) is the new candidate for Firehouse 51. He was previously the candidate for Engine 37, but was kicked out of his firehouse after freezing up on the apartment fire call. He is sent to the "floater pool", where he takes temporary assignments as a result. He is given a second chance by Mouch and later assigned to Engine 51 under Herrmann. He owns a dalmatian named Tuesday, who hangs around the firehouse when Ritter is unable to find someone to watch her while he is on shift. It is revealed that he became a firefighter because of his uncle, a New York firefighter who was working on 9/11. In "Make This Right", he tries to get Mouch and Otis to make amends after Mouch gets sick of Otis' old man jokes, even going as far as wearing a tacky costume in Molly's to help bring them together before Herrmann tells them to make up. In "Move a Wall", he injures his shoulder on a call after a car runs over a hose he was carrying, leading to Casey berating Herrmann. In "The White Whale", it is revealed that his uncle ended up committing suicide after retiring as a firefighter after showing signs of depression.
Family members and significant othersEdit
- Nancy Casey (Kathleen Quinlan) is the mother of Matthew and Christie Casey who was incarcerated for murdering their verbally abusive father and her husband Gregory in 1997, fifteen years prior to the beginning of the series. She had grown estranged from her children while in prison; it was mentioned that Christie still could not forgive her and would testify against her at each parole hearing, thereby postponing Nancy's release, while Casey only visited on rare occasions. Casey is successful in getting Nancy released on parole after convincing Christie to let go of the past. Nancy stays with her son as part of her parole but things become tense between mother and son when Casey voices his discomfort over her going out with "a penpal" just hours after being released. She moves in with her former cellmate, but not before telling her children to mend their relationship. Prior to the character's introduction, Casey almost never mentioned any family members. Only Dawson knew about his having to testify at Nancy's parole hearing while his two most senior firefighters Herrmann and Mouch both mentioned that Casey's family was a taboo topic. When Nancy came to visit him at the firehouse, he was visibly uncomfortable with her presence.
- Renee Royce (Sarah Shahi) is the ex-girlfriend of Lieutenant Kelly Severide Renee becomes attracted to Kelly after he saves her in a traffic accident, and they begin dating. In the season 1 finale, she announced that she is pregnant with Kelly Severide's child. In season 2, it is revealed that the baby is not Severide's.
- Benjamin "Benny" Severide (Treat Williams) is Kelly's father and a fire Chief who served with Chief Wallace Boden and Peter Mills' father Henry Mills. He is a skilled arson investigator currently with the CFD's Office of Fire Investigation Division (OFI). The elder Severide seems well known within the CFD, with various characters, mainly the "white shirts" (high-ranking officers), referring to Kelly as Benny's son. In season 2, Gail McLeod plots a way to overthrow Chief Boden and recruits Benny to see if he will command 51. He accepts but then he backs out because of his longstanding friendship with Wallace. He and Chief Boden had fallen out after the death of Henry Mills in the line of duty to the point where they even argued in front of Boden's men at the firehouse but both have been able to set aside their differences when needed. Benny had a love-hate relationship with his son as he had left Kelly and his mother when the latter was ten years old and had Katie, Kelly's half-sister, with another woman. He lived in Kenosha, Wisconsin with his new wife Beth and two sons but abandoned them and moved to Chicago without Kelly's knowledge. Kelly only finds out when Beth personally introduces herself to him and asks him to tell Benny to come home for the boys' sakes. In season 2, he was implied to be responsible for the disappearance of Vince Keeler, the mobster behind Katie's kidnapping, and confesses to Detective Voight. Voight, being a father himself, lets Benny off and Benny returns to Kenosha on his advice.
- Cindy Herrmann (Robyn Coffin) is the wife of Christopher Herrmann, and mother of their five children (4 boys and 1 girl). In the episode "Under the Knife" Herrmann announces that Cindy is pregnant with their fifth child. In "Ambition" she has a medical episode as a result of the pregnancy and passes out and is rushed to the hospital. In "Hell of a Ride" she has a baby boy. As she is Catholic and does not use birth control because of religious restrictions, Herrmann surprises her on their twentieth anniversary by getting a vasectomy.
- Elise Mills (Alexandra Metz) is Peter Mills' sister. She helps run the family restaurant with her mom and is torn between being protective of Peter and encouraging him to follow his passion for public service.

- Clarice Carthage (Shiri Appleby) is introduced as the pregnant ex-girlfriend of Leslie Shay. In season 1, episode 13, Shay and Clarice reconcile their relationship and Clarice moves back in with Shay, only for Clarice to break up with Shay for a second time at the end of season 1, episode 16.
- Gail McLeod (Michelle Forbes) is a financial consultant hired by the state to help trim the budget of the CFD which includes closing some firehouses. She had Lieutenant Spellman, a transfer from a closed firehouse, "report" to her on the activities of the crew at 51 but Spellman was coerced into transferring out when the entire crew, led by Lieutenants Casey and Severide, staged a plan to run him out upon discovering that he was the mole. Mouch rallies the union to fight back when he discovers the reason why McLeod was so keen on closing down firehouses. The community and fellow firefighters rally behind 51, drawing the attention of State Senator Wheeler, who orders his assistant Isabella, then-girlfriend of Peter Mills, to reverse the closure of 51.
- Connie (DuShon Monique Brown) is Boden's secretary. She is feared by the other firefighters for her no-nonsense attitude and acerbic wit. Mouch notably had "his couch" confiscated when he tried to push his union paperwork to her and only got it back after apologizing to her twice. Boden once quipped that his "entire relationship with Connie is based on asking her for as little as possible." Nonetheless, Connie has been known to be extremely protective of Chief Boden and Firehouse 51. She is implied to have been the one to file a complaint against Firefighter Candidate Rebecca Jones for her sexual innuendo-laced prank on Herrmann as she has repeatedly made known her dislike of Jones. She is well known for her inability to keep secrets. Executive producer Derek Haas commented that Brown's unexpected death towards the end of Season 6 posed a unique challenge for the writing team and they chose not to immediately address the character's absence in latter half of the season. In the season 7 premiere, during the firehouse meeting, Boden tells the team that Connie had completed her master's degree in counseling and left the CFD to fulfill her dream of becoming a counsellor.
- Jack Nesbitt (Eric Mabius) is a former firefighter who started a nightclub-cum-strip club called "Stilettos" and initially appeared to be a success story of a firefighter smoothly transitioning into civilian life. He contacts Casey, an old acquaintance, to do renovation work for the club. Casey begins to suspect something was going on after seeing some foreign-looking men in Nesbitt's office and Nesbitt attempts to get him to join as a "business associate". Detective Voight then alerts Casey that the CPD has been suspecting Nesbitt for human trafficking but were unable to nail him with solid evidence. One of the strippers Katya later tells Casey that she has collected information on the trafficking ring operating out of Stilettos, confirming Voight's suspicion. It is revealed that Nesbitt was actually a double agent; he was colluding with Bulgarian criminals and profiting from the trafficking ring while feeding the FBI information about the Bulgarians' criminal activities. He is eventually arrested by Voight and the FBI.
- Katya L. Antov (Izabella Miko) was a 27-year-old Bulgarian emigrant working at a nightclub Casey was contracted to do renovation work for during the latter half of season 3. She had gathered information on a trafficking ring running out of the nightclub and went to Casey's apartment to ask for his help. Casey tells her that he was helping Detective Hank Voight in doing undercover surveillance to find evidence so the Chicago Police Department could shut down the trafficking ring. They were ambushed by Bulgarian criminals and she was shot execution-style in front of him. Her death would haunt Casey for the first several episodes of season 4.
- Detective Antonio Dawson (Jon Seda) is a Chicago Police Department detective assigned to District 21 and older brother of Gabriela "Gabby" Dawson. He is enlisted by Casey for help when Casey runs into trouble with the seemingly dirty CPD Detective Hank Voight. He is later almost killed in an undercover job gone bad, and joins District 21's Intelligence Unit run by the newly out of prison Hank Voight. Whenever a firefighter at Firehouse 51, where Gabby works, has a run-in with the CPD, Antonio is often called in due to his good relationship with Boden and the firefighters. He and his (ex)wife Laura have two children: Diego and Eva.
- Detective Hank Voight (Jason Beghe) is a seemingly dirty cop who clashes with Lieutenant Matthew Casey (in the episode "Professional Courtesy") after Voight's son's drunk driving paralyzes a teen. Voight covers for his son and targets Casey when he refuses to back down. He was imprisoned for trying to have Casey murdered but has since been released and promoted to sergeant. He heads up the Intelligence Unit of Chicago P.D. and has since been working with Casey to track down the person or people involved with the death of his ex-fiancée. At the end of season 1 episode 23, it is shown that Voight is actually posing as a dirty cop in an undercover collaboration with Internal Affairs to smoke out criminals and other dirty cops. Due to his history with Casey, Voight is still largely despised or viewed with suspicion by the men at Firehouse 51. He does earn their grudging respect with his dedication to finding justice for victims. Voight stated on Chicago P.D. that he considers firefighters "one of our own" and has gone out of his way a number of times to help them and their family members when necessary. He returns to seek Casey's help in investigating a suspected human trafficking ring operating out of a nightclub at which Casey was doing renovation work for. In season 4, he personally arrests Jack Nesbitt, owner of the nightclub, as the latter was about to shoot Casey to cover his tracks.
- Detective Erin Lindsay (Sophia Bush) is a colleague of Antonio's and previously dated Lieutenant Kelly Severide. She was one of the detectives assigned to investigate the kidnapping of Severide's half sister Katie. They break up by season 3 when Severide spirals out of control after the death of his best friend and co-worker Leslie Shay. With the premiere of Fire spin-off Chicago P.D., she has had an on-off relationship with her partner Detective Jay Halstead.
- Detective Jay Halstead (Jesse Lee Soffer) is a detective with the Intelligence Unit who was first introduced as an undercover cop. He was posing as "Jay", a regular customer at Molly's, and begins a relationship with Gabriela Dawson, sister of his colleague Antonio. She discovers he was a henchman of Arthur, a mobster who has been harassing Gabby and her fellow firefighters and joint owners at their bar Molly's. Feeling betrayed, she dumps him and is about to call the police when Antonio reveals to her that "Jay" was actually his co-worker Detective Jay Halstead. Halstead eventually successfully takes down and arrests Arthur, but not before taking a bullet to his shoulder. He and Gabby mutually agree to part ways. In season 2, he appears again, this time to investigate whether Clarke, one of Severide's men, was involved in the murder of his wife's ex-lover.
- Desk Sergeant Trudy Platt (Amy Morton) is the fiancée of Mouch, one of the firefighters at 51. They first met at Chief Boden's wedding reception in the season 2 finale and began dating. She often dotes on him, much to the envy of his colleagues.
- Greg "Mouse" Gurwitch (Samuel Hunt) is the tech analyst at the 21st District. Lieutenant Severide asks for his help regarding a potential cover-up after some files on Gabby's computer were deleted.
