The Flash is an American television series developed by writer-producers Greg Berlanti, Andrew Kreisberg and Geoff Johns, and is based on the DC Comics character, the Flash. The series premiered on The CW television network in the United States on October 7, 2014. The series is a spin-off from Arrow, a show set in the same fictional universe.

The first season follows police forensic investigator Barry Allen (Grant Gustin), who develops super-speed after he is struck by lightning. In his attempt to use his powers for good, he is assisted by S.T.A.R. Labs' Dr. Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes), and Dr. Harrison Wells (Tom Cavanagh). Barry tries to solve the murder of his mother by a superhuman attacker (Matt Letscher). The murder investigation unjustly imprisoned his father (John Wesley Shipp), leaving detective Joe West (Jesse L. Martin), father of his best friend, Iris (Candice Patton), to take in the young Barry. The memory of his mother's murder and his father's framing later motivates Barry to put his personal needs aside and use his powers to fight against those who hurt the innocent, thus, shaping him into the Flash.

The following is a list of characters who have appeared in the television series. Many are named after (or based on) DC Comics characters.

Main charactersEdit

Barry Allen / FlashEdit

Grant Gustin

Bartholomew Henry "Barry" Allen (portrayed by Grant Gustin; season 1–present) is an awkward assistant crime-scene investigator (CSI) for the Central City Police Department (CCPD), who moonlights as the Flash. Barry is traumatized as a child (portrayed by Logan Williams) when his mother, Nora, is murdered by the Reverse-Flash. His father, Henry, is framed for the crime. Joe West becomes Barry's legal guardian, and Barry tries to discover what happened that night. He first appears in Arrow, personally investigating a superhuman-related crime in Starling City. Barry is a fan of the Arrow's exploits and learns Oliver Queen is the vigilante; they become good friends. Sometime after Barry returns to Central City, he is struck in his laboratory by lightning which was affected by dark matter from the explosion of the S.T.A.R. Lab's particle accelerator.

In season one, Barry awakens from a nine-month coma and finds himself with superhuman speed. He uses his new powers to fight crime and hunt other metahumans in Central City as the Flash, a masked superhero, while he tries to identify his mother's murderer. He reveals his feelings for Iris West, who he has loved since childhood, complicating her relationship with Eddie. Barry learns from a 2024 newspaper in the Time Vault at S.T.A.R. Labs that he may eventually marry Iris. He becomes good friends with Cisco, Caitlin, and Dr. Wells, his idol and mentor on missions. Although Wells advises Barry on how to adapt and increase his powers, Barry becomes suspicious of Wells who he is learns is Eobard Thawne (a.k.a. Reverse-Flash) in disguise. After Eobard is unmasked, he tells Barry about his plan to use the Flash's speed and the particle accelerator to generate a portal to his own time (allowing Barry to return to the night of his mother's murder and prevent it). Barry travels back in time, but is warned by his older self not to interfere. As a result, he lets time run its natural course but uses his time-traveling to say a final goodbye to his mother before she passes away. Barry returns to the present and fights with Eobard, stopping him from returning to the future. Although Barry is almost killed, Eddie sacrifices himself to destroy Eobard. This creates a miniature black hole, which Ronnie stops with his own life.

In season two, Barry becomes reclusive after Eddie and Ronnie's deaths, until a near-death experience convinces him to work with his friends again. He discovers a recording of Eobard's confession of Nora's murder that clears his father of all charges, with Barry inheriting Harrison Wells' fortune and resources from Eobard. Though rich, Barry chooses to continue working for CCPD while using Wells' money to fund his and his allies' activities. Barry and his team soon learn of the multiverse when metahumans from Earth-2 target him under orders from Zoom, receiving aid from the Earth-2's Dr. Harrison "Harry" Wells. Barry struggles with his choice to not save his mother and his hatred of Eobard, gradually accepting Harry as a friend upon learning that he is trying to save his daughter Jesse. The group are aided by Earth-2's Flash, Jay Garrick, before they learn that he is actually a time remnant clone of Hunter Zolomon, a.k.a. Zoom, and he steals Barry's Speed Force to cure his terminal illness. After sacrificing his powers to save Wally from Zoom, Harry helps Barry recreate the events which gave him his speed, but Barry disappears into the Speed Force as it helps him move on from his mother's death. After returning and defeating Zoom's army, Barry is forced to watch his father's death in his childhood home. He avenges his father by luring the Time Wraiths to Zoom, who is dragged into the Speed Force while being transformed into the Black Flash. After freeing the real Jay Garrick, Henry's Earth-3 counterpart, Barry goes back in time to avert his mother's death without considering the consequences.

In season three, Barry saves his mother from Reverse-Flash and creates a new timeline (called "Flashpoint" by Eobard) in which he is no longer the Flash. In this timeline, Barry is a CSI without any connection to Iris' family. Barry's memories are overwritten by the new timeline along with losing his powers, forcing Barry to release Eobard in order to restore the timeline. Barry learns his actions have made vast differences to the timeline and he goes back in time again in an attempt to further restore the original timeline. Garrick stops Barry and convinces him to live with his mistakes from creating the "Flashpoint" timeline. As Barry accepts Wally's transition into Kid Flash and trains him, Barry struggles with the temptation to use his powers for personal gain. His struggles worsen upon learning the identity of Savitar, a clone of a future version of himself. After the rogue time remnant is killed, Barry takes Savitar's place in the Speed Force prison to atone for causing the events of season three to occur. He appoints Wally as the new Flash before taking his leave.

In season four, after being stranded in the Speed Force for six months, Barry is freed after Cisco builds a device mimicking his essence so that it can take his place there. Initially, he apparently lost his sanity due to his time spent in the Speed Force. However, after Iris is kidnapped by a Samuroid sent by a mysterious party, Barry rescues her and his health is restored. He claims that has no memories of his initial madness. Barry and the team later realize that the party who sent the Samuroid is stalking them and had strategically manipulated events surrounding Barry's return, creating twelve new metahumans in order to challenge them for a yet-to-be-known purpose. Barry discovers the culprit is Clifford DeVoe. After defeating the invaders from Earth-X, Barry and Iris are married by John Diggle. However, DeVoe frames Barry for murder shortly afterwards; not wanting to risk compromising his loved ones and allies by revealing his secrets, Barry allows himself to be sentenced to life imprisonment at Iron Height Penitentiary by Judge Hankerson, staying in his late-father's cell. A month later Ralph Dibney uses his new shapeshifting power to impersonate DeVoe and help clear Barry of all charges. Through his imprisonment, Barry learns that DeVoe needs to steal the bus metahumans' powers for his scheme. Barry is forced to take a leave of absence from the CCPD because of lingering suspicions and becomes a private investigator under Ralph. Barry also discovers he could lend his speed to people in near proximity, therefore letting them to enter his Flashtime.

Gustin also portrays Savitar (voiced by Tobin Bell in his exosuit and Andre Tricoteux in the character's initial portrayal), who is a temporal duplicate of Barry from the future (created due to a bootstrap paradox) and the main antagonist of season three. The time remnant, shunned by Team Flash, would name himself after the Hindu god of motion while establishing himself as the first metahuman in recorded history by using a powered exoskeleton and the Philosopher's Stone to enhance his abilities.[citation needed] As Savitar is a clone of Barry's possible future self, he is essentially what Barry would become if he gave into his dark impulses. Following his imprisonment in the Speed Force after a battle with the Flash in 2021, Savitar takes advantage of Barry's post-Flashpoint paradox to regain his freedom and cement his existence by killing Iris West so that Barry would be in the right state of mind to ensure his creation.[1] After H.R. Wells averts Iris' death, Savitar makes two final attempts to preserve his existence, but is defeated by Team Flash and killed by Iris. His body fades from existence.

Gustin also plays the Earth-2 non-metahuman Barry, a CSI at the CCPD and Ph.D. graduate who is married to Iris,[2] an alternate timeline version of Barry from season one who is amazed of meeting his near-future time-traveling self, and a version of the Flash from an alternate 2024 who was broken from his battles against Savitar and told his younger self of physicist Dr. Tracy Brand.

Iris WestEdit

Candice Patton

Iris Anne West-Allen (portrayed by Candice Patton; season 1–present) is the daughter of detective Joe West and the wife of Barry Allen. She is based on the DC Comics character of the same name.

In season one, Iris is a barista studying journalism. After graduating, she becomes an investigative reporter for the Central City Picture News. Iris, fascinated by the Flash, wants to learn more about him. She begins dating her father's partner, Eddie Thawne, while Barry is in a coma. When Barry admits his feelings about her, she is conflicted. She later confesses her love for Barry, but he goes back in time and negates the events of that day. Iris learns that Barry is the Flash after he saves her from Reverse-Flash. She feels betrayed by Barry for keeping secrets and further upset at her father for conspiring with him. Iris chooses Eddie, and she and Barry decide to let things proceed between them naturally. However, Eddie kills himself to prevent Reverse-Flash from being born, and Iris is sent into a deep depression.

In season two, Iris becomes more involved with the S.T.A.R. Labs team. She encourages Barry to pursue a relationship with Patty Spivot. Iris learns that her mother is terminally ill and gave birth to a son, Wally, after abandoning her family. She tells her father about Wally, and they meet him at Christmas. Iris forgives her mother on her deathbed and bonds with Wally after she saves his life. She accepts Eddie's death after seeing his video message (recorded by Barry when he is time-traveling) in which he tells her how happy she makes him. Iris reconsiders a relationship with Barry after he breaks up with Patty, and professes her love to him near the end of the season.

In season three, during the Flashpoint timeline, Iris assists Wally who fights crime as the Flash. In the reset timeline, Iris reconciles with Joe after Barry reveals the changes. Iris and Barry begin their romantic relationship, but she wonders if she really is needed. Barry reassures her, saying that there would be no Flash without her. Iris and Barry become engaged after an encounter with Music Meister. An alternate future Iris is killed by Savitar, but Barry tries to prevent her murder. Ultimately, H.R. takes her place for Savitar to kill which changes the future. She, along with Barry, tries to talk down Savitar, but he continues his plan and attacks Barry when it is foiled. Iris shoots Savitar through the back to save Barry.

In season four Iris takes on a leadership role with S.T.A.R. Labs, working with Cisco and Wally when Barry is in the Speed Force. After Barry returns, their church wedding is interrupted by Earth-X invaders, and Barry and Iris are married by John Diggle. However, the DeVoes frame Barry for murder shortly after, leading Iris and her family and friends to try to prove Barry's innocence.

Patton also portrays the Earth-2 Iris, a detective for the CCPD who is married to Barry.[2] Mourning her father, Iris is comforted after she helps Team Flash deal with Zoom.

Caitlin Snow / Killer FrostEdit

Danielle Panabaker

Dr. Caitlin "Cait" Snow (portrayed by Danielle Panabaker; season 1–present) is a bioengineer who works at S.T.A.R. Labs. She is based on the DC Comics character of the same name.

In season one, she provides the medical support for Barry's team. Caitlin grieves her fiancé Ronnie Raymond,[3] who she lost in the particle accelerator explosion. After embracing her loss, she becomes more compassionate and kind. She discovers that Ronnie survived and merged with Professor Martin Stein into the metahuman Firestorm. Caitlin convinces Stein to let her team help separate the two, which is successful. Ronnie and Stein leave Central City following an encounter with General Wade Eiling. After Dr. Wells is exposed as the Reverse-Flash, Caitlin is skeptical until Cisco and Joe find the real Dr. Wells' corpse and discover their mentor's true identity. Ronnie and Caitlin marry when he returns to help Barry and Oliver Queen against Reverse-Flash.

In season two, Caitlin is widowed following Ronnie's sacrifice to stop the singularity. She works at Mercury Labs before returning to S.T.A.R. Labs to aid Barry against Zoom. She is not skeptical of Dr. Harrison "Harry" Wells of Earth-2 and begins a romantic relationship with Jay Garrick, the Earth-2 Flash. Caitlin and Harry develop "Velocity-6" to grant temporary speed, once she learns Jay is dying. It is perfected to Velocity-9, which repairs Jay's damaged cells and restores his speed. Caitlin is devastated when the team discovers Jay is actually Zoom, a.k.a. Hunter Zolomon. Hunter abducts Caitlin to bring her to Earth-2. After meeting her doppelgänger, Killer Frost, and almost getting murdered, Zoom brings Caitlin to Earth-1 to watch him conquer it. Hunter tries to manipulate her into turning evil, believing Caitlin has darkness inside her. Caitlin returns to S.T.A.R. Labs unharmed to aid Team Flash, though afterward she suffers acute stress disorder, seeing visions of Zoom.

Panabaker also portrays the metahuman villainess Earth-2 Caitlin, known as Killer Frost, who is married to Deathstorm (Ronnie Raymond of Earth-2) and works for Zoom along with Reverb.[2] Earth-2 Caitlin did not finish medical school and became a criminal. After the particle accelerator explosion on her Earth, Caitlin develops the powers of cryokinesis and becomes Killer Frost. Her powers turned her hair white and her lips and eyes blue; she is unable to touch anyone without exposing them to absolute sub-zero temperatures and killing them. The only person immune to this is Ronnie, who merges with Martin Stein and becomes a pyrokinetic entity with an almost supernova level of heat. Initially betraying Zoom's Earth-1 enemies, Caitlin helps them escape from Earth-2. After Zoom murders Ronnie, Caitlin tries to murder her doppelgänger out of revenge; Zoom kills her for this.

In season three, she is a pediatric ophthalmologist in the Flashpoint timeline. In the reset timeline, Caitlin has developed cryokinetic abilities, which she has very little control over. Her lips turn blue and her hair becomes white, which prompts Caitlin to use power cuffs to dampen her powers. Cisco vibes her future as Killer Frost, and Caitlin reveals her powers to the team in which Barry blames himself for her condition afterward. Caitlin uses her powers to rescue Barry from Savitar, which worsens her condition. Her developing powers have psychological effects, which cause her to develop a form of dissociative identity disorder. The Killer Frost persona takes over and aligns herself with Savitar after he unmasks himself as a time remnant of Barry. Savitar has Caitlin kill the Black Flash with her powers. However, Caitlin regains control over herself and helps Team Flash against Savitar. Despite Julian and her mother developing a cure for her condition, Caitlin leaves to find herself. In an alternate 2024 Caitlin is a metahuman villainess like her Earth-2 doppelgänger.

In season four, Caitlin helped Cisco bring Barry back from the Speed Force. She has better control of her powers which she can suppress at will. She struggles for control with her Killer Frost personality as a result of taking the cure, which partially worked. Caitlin also has problems with the city's criminal element after working for metahuman criminal Amunet Black when Barry was in the Speed Force. Iris helps both of Caitlin's personalities accept each other. However, Caitlin loses her powers after a fight with Clifford DeVoe who tells her to thaw. Following Flash's fight with Siren-X, Caitlin sees in an analysis that Killer Frost is still in her and works to find a way to bring her out again. In the meantime, she makes use of a cryonic weaponry from Cisco which simulates the use of her lost powers. Blacksmith theorizes that Caitlin was unable to access Killer Frost due to the placebo effect. Following the defeat of Norvak, Caitlin tells Joe West of this theory and plans to test it out. Later on, Caitlin gets Cisco to help with a memory where it recapped to her that she first turned into Killer Frost at a young age, therefore she has been already a metahuman long before the particle accelerator explosion and Barry possibly not responsible for her condition from his time traveling actions as he believed.

Eddie ThawneEdit

Rick Cosnett

Edward "Eddie" Thawne (portrayed by Rick Cosnett; main season 1; guest seasons 2–3) is a CCPD detective who recently transferred from Keystone City.

In season one, Eddie is Joe West's partner and Iris West's boyfriend. He is initially jealous of Barry because of his childhood bond with Iris. Eddie is suspicious of Barry's true feelings for Iris despite denials, though Barry and Eddie do eventually become good friends. Eddie teaches Barry how to box, which, in addition to the trainings provided by Oliver Queen, helps Barry becomes a capable combatant. Eddie initially sees the Flash as a menace and is head of a task force dedicated to capturing the hero. He changes his perception of the Flash after a near-death experience with the Reverse-Flash. He learns of Barry's secret identity and helps in the investigation of Harrison Wells as the Reverse-Flash. Eddie later discovers that he is a forefather of Eobard Thawne and that Iris may eventually marry Barry. However, after a conversation with Martin Stein, Eddie realizes that the future is not set and chooses to stop his sociopathic descendant by killing himself, dying in Iris' arms while causing Eobard to vanish. His body is sucked into a wormhole caused by Eobard's manipulations.

In season two, Eddie briefly appears in a vision as a result of Barry's guilt towards his death, and a memorial is set up in the precinct in his honor. Eddie's name is referred from a list of contacts on a phone at Earth-2 Barry and Iris' home, implying his Earth-2 doppelgänger's existence.[2] Eddie later appears again when Barry travels back in time, and Barry offers to make Eddie a video message to Iris so that she can have closure from his death and move on.

In season three, the Speed Force takes the form of Eddie to help teach Barry to realize the true meaning of sacrifice and that he must be the one to save Iris from Savitar.[4]

Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne.[5]

Cisco Ramon / VibeEdit

Carlos Valdes

Francisco "Cisco" Ramon (portrayed by Carlos Valdes; season 1–present) is a mechanical engineering genius who works at S.T.A.R. Labs. He is also a metahuman superhero codenamed Vibe. He is based on the DC Comics character of the same name.

In season one, Cisco is a scientist at S.T.A.R. Labs who has a very relaxed comedic wit,[according to whom?] with a tendency to nickname the metahuman villains they face. He develops equipment and arsenal for Barry and his vigilante allies. Cisco forms a friendly bond with Ray Palmer (the Atom) because of their genius intellects, and is an admirer of Dinah Laurel Lance (Black Canary). Cisco is on bad terms with his brother Dante. Despite his close friendship with Barry, Cisco is afraid of the metahumans and fears that his friend may go rogue like his enemies. He develops various measures including cryonic and heat guns to counter the Flash's powers, but they are stolen by criminals Leonard Snart and Mick Rory for that very purpose. Although Wells considers him a surrogate son, Cisco is killed for discovering Wells' true identity, though Barry later resets the timeline; Cisco retained the memory of his murder and the knowledge of the Reverse-Flash's true identity. Cisco learns from Eobard that this is because he was also affected by the particle accelerator's explosion, having the ability to see into alternate timelines and realities.

In season two, Cisco is a technical advisor and metahuman task force armorer for the CCPD, building devices to counter super-criminals. He frequently works with Joe West. Cisco's metahuman abilities develop further, allowing him to see visions (or vibes) including precognition. He uses his abilities to locate Earth-2 metahumans through touch, though he is not yet in full control of them. Martin Stein is the first to discover his secret. Cisco is forced to reveal his powers to the team because of Harry Wells of Earth-2. Cisco adopts the codename "Vibe" and receives a retrofitting visor that can help him control his powers. He initially struggles to trust Harry due to his experience with Eobard, but he realizes that Harry is not like Eobard. Despite it, he still cannot get along with Harry due to contrasting personalities, even admitting that Eobard was a nicer guy. He briefly dates Kendra Saunders. After encountering his Earth-2 doppelgänger, Reverb, Cisco fears that he is on the path to becoming a villain. However, Cisco tries to harness his powers for heroic purposes. Cisco also meets his brother's Earth-2 doppelgänger, Rupture, after Zoom frames him for Reverb's death. After this, Cisco and Dante reconcile. During an encounter with the Black Canary's Earth-2 doppelgänger, Black Siren, Cisco briefly displays a powerful sonic attack against her. He also develops the ability to open portals to parallel universes.

The Earth-2 version of the character (also portrayed by Valdes) is the metahuman villain Reverb, who works for Zoom, along with Killer Frost and Deathstorm, before he is killed by Zoom.[2] Cisco has more experience and control of his powers than his Earth-1 self; he has been aware of Vibe's existence and powers even before Earth-1 Cisco appears on Earth-2. He can manipulate sonic vibrations to create powerful shock waves of considerable strength, and it is implied that Cisco's power level surpasses both Killer Frost and Deathstorm as they are intimidated by him. His visor technology is obtained by his Earth-1 counterpart following his death, and Harry later uses its components to modify Vibe's own visor.

In season three, Cisco is a billionaire tech magnate in the Flashpoint timeline, profiting with his inventions but also secretly helping Flash (Wally West) and Iris. In the reset timeline Cisco is coming to terms with his brother's death, but his grief worsens when Cisco learns that Barry is inadvertently responsible for Dante's death; their friendship is strained for a while. However, Cisco and Barry reconcile after Cisco inadvertently alters history to the worse during the Dominators invasion. Cisco starts to use his powers more, but he refuses to utilize their destructive potential like Reverb. He gains confidence that he is not on the same path as his Earth-2 doppelgänger and builds a prototype suit prior to Dante's death. Cisco's refusal to fully use his powers against Killer Frost gives her a psychological advantage over him. His rejection of his dark side eventually inspires Caitlin to do the same. Cisco shares a budding romance with Cynthia Reynolds (Gypsy), a metahuman bounty hunter from Earth-19. Cisco also struggles to build a friendship with Harrison "H.R." Wells from Earth-19, not because of his experience with Eobard Thawne but of both he and Harry see him as a nuisance. In the alternate 2024, Cisco lost his hands after the fight with Killer Frost, and thus the use of his powers. He replaced them with cybernetic prostheses and is dejected after Savitar's attacks has left Central City without a sense of hope.

In season four, Cisco succeeds in bringing Barry back from the Speed Force after six months of building a device that mirrors Barry's essence with help from Felicity, Harry, Caitlin, Tracy, Christina "Tina" McGee, and Curtis Holt. After Barry is sentenced to prison after the DeVoes framed him for murder, Cisco works with Ralph Dibny, who substitutes for the Flash as the Elongated Man. He and Gypsy break up when they realize their careers and lives are keeping them apart.

Harrison WellsEdit

Tom Cavanagh

Dr. Harrison Wells (portrayed by Tom Cavanagh; season 1–present) is the mind and money behind the S.T.A.R. Labs particle accelerator in Central City.

In season one, he activates a particle accelerator that releases dark matter energy in Central City, killing several civilians and granting various individuals metahuman abilities, including Barry Allen. Nine months later, Wells is a recluse and a pariah, confined to a wheelchair. Along with Cisco Ramon and Caitlin Snow, he helps develop Barry's powers as the Flash and mentors him in pushing his speed to the limit to come up with novel solutions to take down metahuman criminals. However, Wells has many secrets: he is faking paralysis, possesses the artificial intelligence Gideon which has information from the future, and is willing to kill to protect his protégé and cover his own tracks. Wells is revealed to be the Reverse-Flash, the mysterious speedster in a yellow suit who killed Barry's mother in 2000. It is also revealed that Eobard Thawne killed the real Harrison Wells, along with his wife Tess Morgan, and assumed his identity; he orchestrated the events that would turn Barry into the Flash for his own agenda. Eobard's plans are foiled and he is erased from existence when his ancestor Eddie Thawne commits suicide, though the Reverse-Flash's existence lingers to preserve the timeline. In season two Eobard's last will as Harrison Wells contains a recorded confession for Barry that clears Henry of all charges. In season four a time-remnant version of Eobard, who remains the under the guise of Harrison Wells, appears in the Crisis on Earth-X crossover. This time remnant settled in Earth-X and governed the Nazi-ruled Earth with Dark Arrow (Oliver Queen's doppelgänger), Overgirl (Kara Danvers' doppelgänger) and Prometheus (Tommy Merlyn's doppelgänger) as a member of the New Reichsmen.

Season two features the Earth-2 version of Dr. Harrison "Harry" Wells, the father of Jesse Wells. He, like Eobard, used an exploding particle accelerator to create metahumans, including the psychopathic serial killer Hunter Zolomon as the rogue speedster Zoom. Harry refused to take responsibility while making a profit by developing metahuman detector technology. But when Zoom kidnaps Jesse, Harry travels to Earth-1 to assist Barry in the fight against Zoom's metahumans and to locate Jesse. Team Flash, specifically Cisco and Joe, distrust him because of the prior betrayal by Eobard, and Harry himself is mistaken by people, unaware that Eobard's actions ruined his Earth-1 doppelgänger's name and legacy. Harry meets the Reverse-Flash's younger self, suspecting that the encounter between them is what caused Eobard's future actions towards his Earth-1 self and lead Harry to hate Thawne. Harry is extorted by Zoom into developing a device to steal the Flash's speed for Zoom in exchange for his daughter's life, a feat that even the Reverse-Flash had failed to achieve. But Harry confesses to his collaboration with Zoom and gains Barry and Cisco's help rescuing Jesse from Earth-2; Harry and Jesse then seek refuge on Earth-1. After Barry's speed is sacrificed to Zoom to save Wally West, Harry recreates a miniature particle accelerator to help Barry regain these powers. Although the accelerator explosion causes Barry to disappear, and its dark matter affects both Wally and Jesse, Harry eventually locates Barry at the Speed Force; with Cisco and Iris' help, Harry brings Barry back and Barry wakes Jesse from the coma. After Zoom's defeat, Harry and Jesse return to Earth-2 with Jay Garrick, promising to help the Flash of Earth-3 return to his own Earth. Harry returns early in season three after Jesse is revealed to have developed super-speed as a result of the accelerator, but Harry asks the team talk his daughter out of pursuing heroics. After Barry and Jesse are forced to team up, Harry becomes more supportive of it. Harry helps Joe protect Iris after they arrive on Earth-2 to hide from Savitar, but they fail to stop her kidnapping. Harry despises his Earth-19 doppelgänger, H.R. Wells, who he considers a moron, but comes to respect H.R. after learning of his sacrifice for Iris. In season four's season premiere, it is revealed that Harry was one of the scientists who helped Cisco develop a device to take Barry's place in the Speed Force. Harry visits Earth-1 again after an argument with Jesse, and helps the team fight Clifford DeVoe.

Season three introduces his Earth-19 version, Harrison "H.R." Wells. H.R. is one of several versions of Harrison Wells that finds the cryptogram sent by Harry through the multiverse and expresses interest in aiding Team Flash. Cisco determines that H.R. is not a scientist; H.R.'s scientist partner at S.T.A.R. Labs, Randolph Morgan, was the one who solved Harry's cryptogram for him. Barry suggests letting H.R. stay a few weeks and he proves his worth by helping form plans and locating super-criminals; like Harry and Eobard, H.R. is a skilled organizer, businessman, and entrepreneur. He trains Wally to be a hero and, after discovering how many criminals breached the facility, strives to transform S.T.A.R. Labs into a museum to maintain Team Flash's cover. Gypsy, an enforcer from Earth-19, arrives to retrieve H.R. on charges of crossing dimensions, but is defeated by Cisco. In the battle against Savitar, H.R. sacrifices himself by disguising himself as Iris and taking her place to be killed by Savitar. In the alternate 2024, H.R. was a successful novelist.

Other versions of Wells appear in the episode "The New Rogues": a gunslinger variant named "Hell's Wells", a steampunk-styled scientist from Earth-17, and a French mime.

During the fourth-season episode "When Harry Met Harry...", Harry briefly creates the "Council of Wells", which consists of the smartest versions of himself from across the multiverse: Harrison Wolfgang Wells, a German author and scientist from Earth-12; H. Lothario Wells, a billionaire and playboy from Earth-47; and Wells 2.0., a cyborg from Earth-22. Also shown is a wizard variant named "Wells the Grey".

Harrison Wells is an original character created for the series while Eobard Thawne is based on the DC Comics character of the same name.[6]

Joe WestEdit

Jesse L. Martin

Joseph "Joe" West (portrayed by Jesse L. Martin; season 1–present) is a CCPD detective, father of Iris and Wally West, and legal guardian to Barry Allen following Nora Allen's death and Henry Allen's incarceration.[7]

In season one, he is one of the few who knows Barry's secret; he reluctantly becomes Barry's partner against metahuman criminals by offering him support in crime fighting. Joe also gives Barry advice on his feelings for Iris. He assists Barry's attempts to prove Henry innocent and secretly investigates Wells, suspicious of his intentions. Joe and the team ultimately discover Wells' true identity.

In season two, Joe is head of the metahuman task-force along with Cisco and Patty Spivot. He relies on Cisco's inventions to deal with the super criminals and becomes a father figure to them both. Joe struggles with his relationship with his estranged wife Francine who, unbeknownst to Joe, gave birth to their son Wally after she left the family. He is distraught and unsure of how to be a father to Wally, but after Zoom kidnaps Wally they become close. Joe is proud of Wally's aptitude in mechanical engineering and his need to help people. After Wally is exposed to the dark matter, Joe suspects that his son will become a metahuman.

In the Flashpoint timeline of season three Joe is an alcoholic who is uncommitted to his job and estranged from his children. He is unaware that Wally is the Flash. In the reset timeline Joe and Iris are not speaking because Joe never told her that her mother was alive; however, they reconcile after Barry reveals the timeline changes. Joe fears for Wally's life after discovering Wally has dreams of being Kid Flash. After Wally becomes a speedster, however, Joe eventually accepts his son's destiny. He begins to move on from his widowhood by dating district attorney Cecile Horton. In an alternate 2024 Joe grieves over Iris' death and Wally's paralysis and catatonia.

In season four, Joe learns that Cecile is pregnant with his child, later revealed to be a daughter. Having a child young enough to be their grandchild cause him and Cecile to experience a midlife crisis that they eventually overcome together. When Barry is incarcerated at Iron Heights, Joe does everything he can to help prove his innocence. When Cecile goes into labour while Flash was in a final battle with Thinker, Joe stays by her as Caitlin helps to deliver their child; he and Cecile later named their newborn daughter Jenna. He later talks to Wally at the party that followed, being proud of his son's new confidence, and they are delighted with Jenna's birth.

Martin also portrays the Earth-2 Joseph West, a singer who does not share a father-son bond with Barry and actually blames him for Iris becoming a police officer. Earth-2 Joseph is killed by Deathstorm and Killer Frost.[2][8]

Wally West / Kid FlashEdit

Keiynan Lonsdale

Wallace "Wally" West (portrayed by Keiynan Lonsdale; main seasons 2–4; guest season 5) is Iris' unknown brother and Joe's son,[9][10] described as "a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark".[11] Based on the DC Comics character of the same name, the character is an amalgamation of his original interpretation and the interpretation that was introduced during DC's The New 52 relaunch.[citation needed]

Wally was born after his mother's abandonment of her family, leading Joe and Iris to be unaware of his existence for eighteen years. Wally first meets his father and sister during a Christmas party shortly before his mother dies, and he struggles to bond with Joe and Iris. He also forms a brotherly bond with Barry Allen, although he is suspicious of Barry's weird behavior. Formerly a drag racer, Wally is enrolled at the same university Iris attended, majoring in mechanical engineering. After repeatedly being rescued by the Flash, Wally becomes fascinated with the superhero and discovers that his father has a connection with him, but is unaware that he is Barry. He is inspired by both his father and the Flash to help people, and as a result becomes closer to Joe. Later, when Wally and Jesse Wells are locked in the Time Vault at S.T.A.R. Labs, they work together to escape but are accidentally affected by the dark matter released from the attempt to restore Barry's powers; his father and Barry suspect that Wally is turning into a metahuman after the incident. Eventually Wally discovers Barry's secrets when Zoom abducts and kills Barry's father, and fully accepts Barry after he rescues Joe from Zoom.

In the Flashpoint timeline, Wally is the Flash,[12] until he is badly injured by the rogue speedster Rival and Barry and Eobard Thawne reset the timeline. In the post-Flashpoint timeline, Wally struggles to become a speedster after witnessing Jesse becoming one. After Alchemy seeks Wally out, Wally learns of his alternate life and uses the villain's device to gain his speed. Wally then becomes a speedster after Caitlin stabilizes his metamorphosis, and he is eager to join Barry as his partner, Kid Flash, to both his father and sister's concerns. Wally also assists Cisco due to his background in mechanical engineering. Barry gradually appreciates Wally's supports and asking Wally's help to save Iris from Savitar. Though H.R. saves Iris instead after he sacrifices himself, Wally and Jay Garrick join Barry in the final battle to defeat Savitar. After Barry chooses to take Savitar's place in the Speed Force to stabilize it, he appoints Wally to be his successor as the Flash. In the alternate 2024, Wally sought revenge against Savitar shortly after Iris' murder but was rendered paraplegic and catatonic after the fight.

In season four, Wally leaves Central City for Blue Valley on a mission of self-discovery after Jesse breaks up with him.[13] He later returned for his sister's wedding. He resumes his journey though, reaching China before being recruited by Rip Hunter to join the Legends in their fight against Mallus. Following the fight with Thinker, Wally attended the party that followed the birth of his father's new daughter with Cecile Horton, and is delighted of having a younger sibling. He told his father about his battle to save the universe from Mallus and how he was working not to be in Barry's shadow, showing Joe his confidence as a hero.

Lonsdale decides that he will not be returning to The Flash full time on season five, due to his desire to seek other acting opportunities.[14]

It was always intended for Wally to be the son of Joe and brother of Iris, which differs from the character's comic history, as the producers felt it "weird" for second seasons of television series to introduce previously unmentioned cousins of established characters.[10] Keiynan Lonsdale originally auditioned for Legends of Tomorrow to portray Jefferson "Jax" Jackson.[15]

Julian Albert / AlchemyEdit

Julian Albert Desmond / Alchemy (portrayed by Tom Felton) - A wealthy scientist and fellow CSI at the CCPD.[16][17] The character was originally known as Julian Dorn.[16] In season three, he works with Barry Allen though they did not initially get along. As Alchemy, he is an acolyte of Savitar who unlocks the potential in metahumans from the Flashpoint timeline in preparation for a future event. Julian is not aware he is Alchemy, and that he only assumes the guise while being unconsciously possessed by Savitar.[18] Tobin Bell voices Doctor Alchemy.[19] In order to fix what he made as Alchemy, Julian decides to join the team to help against Savitar and other metahumans. Julian and Caitlin Snow develop a romantic relationship. In season four, it is revealed that Julian returned to the United Kingdom.

Clifford DeVoe / ThinkerEdit

Clifford DeVoe (portrayed by Neil Sandilands; season 4) is a metahuman with superhuman intelligence, who seeks to fix all that he deems wrong with humanity as the Thinker and the main antagonist of season four.[20] Prior to his appearance, he was alluded to by Abra Kadabra and Savitar as a powerful future adversary. Originally a mild-mannered professor who dreamed of expanding the way people think, Clifford DeVoe used the "thinking cap" his engineer wife Marlize DeVoe built on his specifications and powered it with the dark matter wave from the S.T.A.R. Labs explosion to boost his intelligence. It eventually rendered him paraplegic and with an advanced form of amyotrophic lateral sclerosis, Marlize developing a hoverchair to delay the affliction as he developed a god complex. Having deduced Barry's imprisonment in the Speed Force, the Thinker orchestrated events that to force the Flash's return while arranging the creation of twelve new metahumans on the bus directly exposed to the resulting dark matter wave. He then hunted them to acquire their powers for his own, being steps ahead of Team Flash as he used them to capture Kilg%re and Becky Sharpe (Sugar Lyn Beard) and induct Ralph Dibny into their group while he personally captures the Weeper. Barry soon learns of DeVoe's existence, the villain accepting the "Thinker" moniker Vibe invented while continuing to be steps ahead of the group.

Using Blacksmith to acquire Dominic Lanse (Kendrick Sampson), DeVoe transfers his consciousness into the metahuman's body to acquire his telepathy while using his lifeless original body to frame Barry for murder. This ultimately played to his plan in causing an Iron Heights Prison breakout, acquiring Becky's body and luck manipulation along with the powers of Kilg%re, Black Bison, and Dwarfstar while killing Warden Wolfe to Marlize's horror. This was the start of his personality changing for the worst as, showing indifference upon learning that Barry is exonerated, DeVoe places an extract of Weeper's tears in his wife's drink to make more obedient. He later transferred his mind into the body of Izzy Bowin (Miranda MacDougall) to acquire her powers, leaving only Ralph and four more metahumans to capture. After proceeding to take the powers of Edwin Gauss (Arturo Del Puerto) as well as Melting Point and Null, DeVoe manipulated events that led to him taking Elongated Man's body and thawing Caitlin Snow's Killer Frost form. He then used Elongated Man's powers to shape his body into his own so that his wife can now love all of him. After raiding an A.R.G.U.S. facility, DeVoe begins to put his Enlightenment Satellite plan into action. With help from Marlize, his plot was thwarted while his host regained control of his body when Barry's conscience enters the Thinker's mind to help fight off, during which DeVoe's good side manifested as a corpse, showing that he was truly beyond redemption. With his original body dead and Marlize having destroyed every known means he has to sustain his survival, DeVoe no longer exists.

Cecile HortonEdit

Cecile Horton (portrayed by Danielle Nicolet; main season 5; recurring seasons 3–4; guest season 1) is the Central City district attorney and a close friend of Joe West. She would give occasional legal advice to Joe in season one. Cecile and Joe begin a romantic relationship in season three and expect a child in season four. Nicolet will be promoted to a series regular for season five.[21]

Ralph Dibny / Elongated ManEdit

Hartley Sawyer

Ralph Dibny (portrayed by Hartley Sawyer; main season 5; recurring season 4) is a metahuman with the ability to stretch his body to superhuman lengths and sizes.[22][23] In season one, Ralph's name was referred by Eobard Thawne of him being one of the victims killed by the particle accelerator explosion prior to the timeline change in season three. Dibny was a CCPD detective until Barry testified against him for tampering with evidence. It is later revealed that Dibny committed perjury out of a misguided sense of justice rather than a desire for personal gain: he feared a suspect would get away with murder, and thus planted fake evidence. Dibny then became a shady private detective specializing in infidelity cases. He was on the bus that was exposed to dark matter energy and became a metahuman and ally to Team Flash. After Barry is framed by Clifford DeVoe for murder and imprisoned at Iron Heights, Ralph substitutes Barry as Central City's new superhero Elongated Man, to continue Team Flash's fight against DeVoe and other criminals while working to free Barry. Posing as Clifford DeVoe, he appeared before the judge that presided over Barry's trial claiming that someone knocked him out and made him look dead. This statement convinced Judge Hankerson to exonerate Barry. Elongated Man's body was later taken over by Thinker who stretched it into his own image. During the final battle with Thinker, Elongated Man regained control of his body and helped to defeat him.

Only his son Barry, and later Joe West, believe his innocence. Throughout season one he learns that Barry is the Flash and is proud of his son. Henry serves as Barry's moral conscience in using these powers wisely, thus keeping Barry from being tempted by personal gains. In season two Henry is released from prison due to Eobard's confession to Nora's murder. However, he leaves Central City to seek a reclusive life as he believes that his presence could hold back Barry's duties as the Flash.

Labs to help in Barry's fight to save the world from Zoom. Henry is killed by Zolomon in order for Barry to relive the same tragedy he went through as a child.

  • It is implied that the Earth-2 version of the character has a happy life.[2]
  • Shipp also portrays Jay Garrick, the Earth-3 version of the Flash. Zoom held Jay captive in a failed attempt to harness his speed, and was inspired to take up his persona and falsely operate as the Flash of Earth-2, even using Jay's name. To keep him from escaping, Zoom forced Jay to wear a mask that suppressed his speed and prevented him from talking.

After being freed, Jay joins Team Flash in the final battle to defeat Savitar. Jay later returns to help Barry controls of his new Flashtime powers, and reveals that he plans to retire and trains a protégée to become his successor as the Flash.
    • Regarding the difference in his portrayal of Garrick over Allen, Shipp "figured Jay is my version of Barry" from the 1990 series, adding, "I went back and I watched a couple of episodes of the 1990–91 version to kind of remind myself what I did. [Jay] is much more reminiscent of my Barry Allen from 25 years ago than my Henry Allen. I went back and I was amazed how much attitude my Barry Allen had in some situations. I went back and I picked up that thread and I brought it forward 25 years, and tried to weave it in."[51]


Grodd (voiced by David Sobolov[52]) - A hyper-intelligent gorilla with telepathic powers as a result of being experimented on by General Eiling under the watch of Eobard Thawne.

Hunter Zolomon / ZoomEdit

Hunter Zolomon / Zoom (portrayed by Teddy Sears,[54] initially portrayed by Ryan Handley,[55][56] voiced by Tony Todd[57]) - A speedster from Earth-2 who is obsessed with becoming the only speedster in the multiverse and the main antagonist of season two. Executive producer Andrew Kreisberg said, in season one "with the Reverse-Flash, we just modulated Tom Cavanagh's voice, and this year we wanted to do something a little bit different [for Zoom]. Part of the mystery of the season is who or what is underneath the Zoom outfit, and so we wanted to do something like James Earl Jones as Darth Vader — this iconic voice coming out of this mask."[57] Hunter was a traumatized child (portrayed by Octavian Kaul[58]) that witnessed his mother's murder at his father's hands which triggered his bloodlust as a serial killer before he gained his powers from the particle-accelerator explosion on Earth-2. Dissatisfied, he sought to increase his speed with the Velocity serum but soon discovered it carried a fatal illness. Searching for a cure, he traveled the multiverse and captured Jay Garrick. Unsuccessful in stealing Jay's speed to cure himself, Hunter kept him imprisoned with a speed-dampening mask. Inspired to be both hero and villain, he used Jay's name as the fraudulent Flash of Earth-2 to instill false hope which he would take away as Zoom. Discovering Earth-1, he plotted to increase Barry's speed and then steal it, sending various metahumans from Earth-2 to fight the Flash while also infiltrating the team as Jay. Zoom extorts Harry Wells into physically stealing Barry's speed by kidnapping Jesse Wells. He also becomes Caitlin Snow's love interest.
