Arrow is an American superhero television series developed by Greg Berlanti, Marc Guggenheim, and Andrew Kreisberg based on the DC Comics character Green Arrow, a costumed crime-fighter created by Mort Weisinger and George Papp, and is set in the Arrowverse, sharing continuity with other Arrowverse television series. The series premiered in the United States on The CW on October 10, 2012, with international broadcasting taking place in late 2012 and primarily filmed in Vancouver, British Columbia, Canada. Arrow follows billionaire playboy Oliver Queen (Stephen Amell), who claimed to have spent five years shipwrecked on Lian Yu, a mysterious island in the North China Sea, before returning home to Starling City (later renamed "Star City") to fight crime and corruption as a secret vigilante whose weapon of choice is a bow and arrow.
Throughout the series, Oliver is joined by others in his quest, among them former soldier John Diggle (David Ramsey), I.T. expert and skilled hacker Felicity Smoak (Emily Bett Rickards), former assassin Sara Lance (Caity Lotz), aspiring vigilante Roy Harper (Colton Haynes), Oliver's sister Thea (Willa Holland), and attorney-turned-vigilante Laurel Lance (Katie Cassidy). The group also receives support from Laurel and Sara's father Officer Quentin Lance (Paul Blackthorne). During the first five seasons of the show, characters from Oliver's past appear in a separate story arc based on Oliver's flashbacks, which highlight parallels from Oliver's history that shape events in the main story. Starting with season seven, a series of flash-forwards focus on Oliver's children William and Mia, exploring how present events would affect their future and Green Arrow's legacy.

Oliver Queen / Green ArrowEdit
Oliver Jonas Queen (portrayed by Stephen Amell; main: season 1–present) is a billionaire playboy who returns to his home of Starling City after being apparently stranded on a desert island for five years and presumed dead. On his return, he embarks on a secret double life as a masked vigilante known as 'The Hood'. In season four, his vigilante persona becomes known as Green Arrow. He also appears in Arrowverse spin-off shows The Flash, Legends of Tomorrow and Supergirl, as well as animated web series Vixen. He also plays a central role in the annual Arrowverse crossover events.
Laurel Lance / Black Canary (Earth-1)Edit
Dinah Laurel Lance (portrayed by Katie Cassidy;[a] main: 1–4; guest: 5–7) is an assistant district attorney and Oliver Queen's ex-girlfriend. She later becomes a vigilante known as Black Canary. The character also appears in Arrowverse spin-off shows The Flash and Legends of Tomorrow as well as animated web-series Vixen.
The character is based on the DC Comics character Black Canary.
Thomas "Tommy" Merlyn (portrayed by Colin Donnell; main: season 1; guest: seasons 2–3, 6–7) is Oliver Queen's best friend and Malcolm Merlyn's son.
In season one, Tommy is a spoiled playboy who lives off Malcolm's financial support. After Malcolm cuts him off, Tommy manages Oliver's nightclub Verdant, and dates Laurel. He learns Oliver's secret when Oliver, as the vigilante, saves Malcolm from assassins. Oliver and Tommy's friendship is strained with Tommy seeing Oliver as a killer. Tommy later breaks up with Laurel, thinking Laurel belongs with Oliver. Tommy is killed rescuing Laurel from a collapsing building damaged by his father's earthquake machine during the Undertaking.
In season two, Oliver vows never to kill again in Tommy's memory. An image of Tommy is seen, calling Oliver a hero. It is also revealed that he is Thea Queen's paternal half-brother. In season three, Tommy appears twice in flashbacks. He travels to Hong Kong looking for Oliver but fails, and throws himself a birthday party while trying to stop Thea from using drugs and grows closer to Laurel. In season five, the Dominators' dream world has him mentioned as a cardiothoracic surgeon after completing his residency in Chicago (a nod to Colin Donnell's role as Dr. Connor Rhodes in Chicago Med after leaving Arrow) and he appears as a ghost when Oliver leaves the dream world.
In season six, Christopher Chance impersonates Tommy dressed as the Green Arrow during Oliver's trial, claiming to have faked his death to protect his vigilante identity. At the end of the season, Oliver clears Tommy's reputation by admitting to being the Green Arrow. In season seven, Tommy appears as a hallucination, guiding Oliver about how to deal with Emiko Queen.
Tommy Merlyn's Earth-X doppelgänger is revealed to be an equivalent of Prometheus in said parallel world seen in the "Crisis on Earth-X" crossover special. Like his doppelgänger, he is friends with the Dark Arrow. Unlike his Earth-1 self, Tommy has skills (and even an amalgam costume style) consistent to Malcolm Merlyn and Adrian Chase, and is a member of the New Reichsmen with Dark Arrow, Overgirl, and the Reverse-Flash. After Sara Lance and Alex Danvers subdue and capture him, Tommy cruelly taunts Oliver over the attachment to his deceased doppelgänger and kills himself via cyanide capsule, leading Oliver to see Tommy's doppelgänger as a perversion.
The character shares his surname with the DC Comics character Merlyn. Tommy Merlyn was later introduced as a former friend-turned-enemy of the titular character in the Green Arrow comics in The New 52.
John Diggle / SpartanEdit
John Thomas Diggle (portrayed by David Ramsey; main: seasons 1–present) is a decorated former United States Army Special Forces soldier, honorably discharged with the rank of master sergeant, an ordained minister, and Oliver's best friend and partner. The character, again portrayed by Ramsey, also appears in Arrowverse spin-off shows The Flash, Legends of Tomorrow and Supergirl, playing a significant role in Arrowverse crossover events. John is also the stepson of General Roy Stewart.
While John Diggle was originally a character created for the show, his popularity led to a character of the same name modeled after Ramsey's appearance to be created for the Green Arrow comics in The New 52. While elements from the Arrow TV series were removed after issue 40, John appeared again following the relaunching of the series as part of DC Rebirth.
Thea Queen / SpeedyEdit
Thea Dearden Queen (portrayed by Willa Holland; main: seasons 1–6; guest: season 7) is the daughter of Moira Queen and Malcolm Merlyn, though both Malcolm and Thea were unaware of their relation to each other until season two, and the younger half-sister to Oliver Queen and Tommy Merlyn. She goes on to become a vigilante known as Speedy.
Her brother's nickname for her and later hero persona ("Speedy"), her middle name of Dearden and the alias "Mia" she used during her time at Corto Maltese, are Easter egg connections to Mia Dearden, one of Green Arrow's sidekicks in the comics.
Moira Queen (portrayed by Susanna Thompson; main: seasons 1–2; guest: seasons 3, 5) is the mother of Oliver and Thea, the former acting CEO of Queen Consolidated, mayoral candidate and wife of Robert Queen and later Walter Steele. She also had a brief affair with Malcolm Merlyn after his wife's death, which resulted in Thea's birth.
In season one, Moira is involved in "The Undertaking", a criminal conspiracy orchestrated by Malcolm to destroy the Glades, with him forcing Moira to handle all interference and supply him with the resources needed. Her involvement causes her to keep many secrets from her family which, when revealed, causes Walter to divorce her and her kids to become distant. Moira eventually confesses her involvement and Malcolm's, which results in her arrest.
In season two, Moira is put on trial but she is acquitted as Malcolm returns, alive. She makes Malcolm go on the run by informing Raʾs al Ghul of his survival. Moira eventually becomes a mayoral candidate against Sebastian Blood on Walter's advice, but the secret of Thea's parentage is revealed, causing a rift between Moira and her children. It is revealed that she had been aware of Oliver's secret identity as the Arrow since the night of her arrest. She is murdered by Slade Wilson as part of his revenge plot against Oliver. In a flashback, Moira paid Samantha Clayton to tell Oliver she lost their baby and to move away to Central City.
In season three, Moira's voice is briefly heard when Oliver calls home from Hong Kong. In season four, Samantha reveals she never cashed Moira's check, and the attempted bribe resulted in Samantha hating Moira; as a result, Samantha denied Moira access to her grandson, William. Oliver is hurt when he finds out, and angry with Moira for the deception.
In season seven, Oliver finds out that Moira had discovered that Robert had had an extramarital affair with a woman named Kazumi Adachi, which resulted in the birth of a girl named Emiko, but chose to conceal their existence. Oliver is further frustrated with Moira because her actions caused the mother and daughter to not be taken care of after his father's death.
The character is based on the DC Comics character of the same name.
Quentin Larry Lance (portrayed by Paul Blackthorne; main: seasons 1–6; guest: season 7) is a deputy mayor, mayor, former police detective and captain, the father of Laurel and Sara, and former husband of Dinah Lance.
In season one, Quentin resents Oliver for causing Sara's death, becoming an alcoholic who throws himself into his work to avoid the pain. After Oliver returns, he openly shows his hatred of him and also hates the Arrow for being against everything Quentin believes in. Quentin attempts numerous times to arrest him, one time using Laurel, which causes her to be distant for a time. He works with the Arrow from time to time and eventually comes to accept him.
In season two, Quentin is demoted to officer; an ally to the Arrow, Quentin becomes his informant and occasional field partner on cases. He struggles to recover from his alcoholism and repair the relationships with his family. After Quentin discovers Sara is alive and the vigilante "Canary", he helps her adjust to life in Starling City. He helps Laurel cope with her pain over losing Tommy, and seeks to rekindle his relationship with Dinah, but she has moved on after their divorce. Quentin later regains his detective title. Following a battle with Slade's forces, Quentin passes out from internal bleeding and falls into a coma.
In season three, Quentin is in recovery, with frequent chest pains, and has been promoted to captain; he uses this authority to disband the anti-vigilante task force. His condition is strained due to assisting the Arrow in the field, and he relies on his new political connections and his subordinates to continue serving the city. Although Laurel kept the information from him, he ultimately learns the truth about Sara's death and Laurel becoming her vigilante successor. Quentin becomes estranged from Laurel and relapses in his alcoholism. He blames the Arrow for Sara's death and is determined to bring him to justice; he learns of Oliver's secret identity from Raʾs al Ghul. Quentin supports Team Arrow when Raʾs plans to unleash the bio-weapon on Starling.
In season four, Quentin is forced to work with H.I.V.E. after Damien Darhk threatens the lives of his family. Oliver discovers this and persuades Lance to become a double agent and report information on Darhk. Darhk gradually becomes suspicious of Quentin, who discovers the source of Darhk's supernatural powers: an ancient artifact. With this information, Mari McCabe destroys Darhk's idol, leaving him powerless. Quentin publicly admits in court his association with H.I.V.E. under Darhk's duress, determined to see justice served, despite endangering his career. He reconciles with Laurel and reunites with Sara after she is brought back from the dead. Quentin begins seeing Donna Smoak, Felicity's mother. After Darhk murders Laurel, Quentin seeks to bring her back the same way Sara returned, only to learn from Nyssa al Ghul that the Lazarus Pit was destroyed shortly after Sara's return. With Donna's support, Quentin copes with his loss without succumbing to alcoholism. After saving the city with Oliver, Quentin is fired and decides to leave Star City with Donna.
By season five, Quentin has broken up with Donna and, now having no one left, returns to Star City and falls back into alcoholism. With encouragement from Oliver, Quentin begins reforming Star City's police force as deputy mayor, working with the Green Arrow to reduce the city's rising crime rate. Quentin also formed the Anti-Crime Unit to combat serious crimes prior to his dismissal from the police, and leads them under his new position when needed, though this puts him at odds with his former colleagues. However, after Evelyn Sharp's fight with Prometheus, Felicity discovers that the shurikens Prometheus used were made from Oliver's old arrow heads stolen from the police evidence lockup, and Quentin finds cuts on him that implicate him and raise doubts of his sanity. Quentin eventually learns that Adrian Chase is Prometheus and responsible for attempting to frame him. Thea convinces Quentin to seek help at rehab after realizing how much Laurel's death is affecting him, and holds the position of deputy mayor for when he recovers. After resuming his position, Quentin befriends one of Oliver's protégés, Rene Ramirez, after Quentin learns of his past encounter with a young Rene when Quentin was a beat officer, and offers Rene a job as his assistant. He also befriends Oliver's chosen successor for the Black Canary mantle, Dinah Drake. When Dinah expresses her hesitance at accepting Laurel's mantle, Quentin gives Dinah his blessing, saying it is what Laurel would want. Quentin later encounters the Earth-2 Laurel and is disturbed to see what his own daughter could have potentially become. By the end of season five, Quentin's fate is unknown due to the destruction of Lian Yu caused by Adrian Chase.
At the beginning of season six, it is revealed that Quentin survived the explosion by taking shelter in the plane like the others, but was left emotionally scarred following his encounter with Laurel's doppelgänger. However, he later shares Oliver's hope for Black Siren of redemption. He later serves as the city's acting mayor following Oliver's impeachment, resulting him at odds with his corrupt subordinates led by crime lord Ricardo Diaz. During Team Arrow's showdown with Ricardo Diaz, Quentin is wounded by him causing Black Siren to push Diaz off the building where he survives. This wound got Quentin hospitalized. Despite the surgeons' attempts to save his life, Dr. Elisa Schwartz told Team Arrow that Quentin passed away when his brain was not getting any oxygen. This left Sara and Black Siren devastated.
During the "Crisis on Earth-X" crossover, Quentin's Earth-X doppelgänger is a Sturmbannführer of the Nazi's paramilitary rank. This Quentin also killed his version of Sara after discovering that she was bisexual. In an episode of the season four of The Flash, reveals that, like his Earth-1 and Earth-2 doppelgängers, he is the father of Earth-X's version of Laurel, who is Siren-X.
The character is based on the DC Comics character Larry Lance, husband to Dinah Drake Lance and father to Dinah Laurel Lance.
Felicity Smoak / OverwatchEdit
Felicity Megan Smoak (portrayed by Emily Bett Rickards; main: season 2–7; recurring: season 1) is an I.T. expert, partner and later wife of Oliver Queen. Felicity is a MIT graduate with a master's degree in cyber security and computer sciences. The character originally appeared as a one-episode guest star in season one, later becoming recurring and was promoted to series regular from season two onwards. The character, also portrayed by Rickards, appears in Arrowverse spin-off shows The Flash, Legends of Tomorrow and Supergirl, as well as animated web-series Vixen. She plays a significant role in the annual Arrowverse crossover events.
In a flashforward to 2040, Felicity is rescued from Galaxy One by her children and joins their resistance movement against the company that has hijacked her Archer security program. After Galaxy One is defeated, Felicity leaves Star City in her children's hands and leaves with the Monitor to a place from which there is no return.
An alternate version of Felicity, again portrayed by Rickards, from Earth-X appears in the "Crisis on Earth-X" crossover event, where she is shown to be interned in a concentration camp.
The character is based on the DC Comics character Felicity Smoak, who in the comics is Ronnie Raymond's step-mother who runs a software company. A version based on Rickards' portrayal was introduced in the DC Comics universe in Green Arrow (vol. 5) #35.
Roy Harper / ArsenalEdit
Roy William Harper Jr. (portrayed by Colton Haynes; main: seasons 2–3, 7; recurring: season 1; guest: seasons 4, 6) is a former street criminal, Thea's boyfriend and a supporter of the Arrow.
In season one, Roy is a small-time criminal who falls in love with Thea after robbing her, and is arrested multiple times by Quentin Lance. He does not see any other way to live until the Arrow saves him from a kidnapping, after which Roy attempts to find the Arrow to help him. Roy later works as a waiter at Verdant.
In season two, Roy often goes out to clean up the streets, until the Arrow convinces him to gather intelligence instead. After being injected with Mirakuru, Roy gains super strength but slowly loses his sanity. The Arrow reveals his identity when Oliver convinces Roy to stop Bronze Tiger. Roy trains with Oliver in order to control his strength, but is forced to break up with Thea. Slade kidnaps Roy to use his blood to create his army, leaving Roy completely insane and causing him to go on a rampage, killing a cop. Roy takes part in the season finale's battle, with his own mask, but he is slightly amnesiac, not remembering anything after breaking up with Thea.
In season three, Roy is Oliver's partner and participates with him in the field. He takes on the alter-ego "Arsenal", though the media also refers to him as "Red Arrow". Thea makes Roy her assistant manager at Verdant, and they eventually get back together. Sara's murder brings the repressed memories of his rampage to the surface and Roy supports the family of the police officer he killed. When Oliver is presumed dead, Roy takes his place as the team's head archer, often teaming with Laurel on missions. After Quentin Lance resumes his manhunt against Arrow, Roy subsequently impersonates Oliver's alter-ego and fakes his own death, leaving Starling City to assume that Arrow is dead so that Oliver can be free. Roy passes on his Arsenal suit to Thea after leaving town.
In season four, after building a new life in Hub City, Roy returns to his vigilante role after the Calculator extorts him to steal technological components and Thea is out of commission. In season five, Roy appears as a hologram when Oliver is about to leave the Dominators' simulated dream world.
In season six, Roy is brought back to Star City by Ricardo Diaz, in an attempt to make him testify that Oliver is Green Arrow in court. As he refuses to betray his friend and former mentor, he is tortured by dirty cops and by Diaz himself. He is then rescued by Oliver and Thea, who put back their shared red hood suit for this. He helps Thea and Team Arrow to fight against Thanatos Guild and leaves the city with Thea and Nyssa al Ghul to find and destroy the Lazarus Pits around world. Later, after Christopher Chance disguised himself as Tommy Merlyn and tells Star City that he was Arrow and is Green Arrow, Roy is now cleared of all charges of being the vigilante. When Oliver revealed to Star City that he was both the Arrow and the Green Arrow, Roy's name was permanently cleared.
Haynes returns as a regular for season seven. He returns to Star City to help Team Arrow battle the Ninth Circle. Due to the Ninth Circle being led by Oliver's half-sister Emiko, he feels he could not ask for Thea's help and instead contacts Roy. Roy reveals that he died battling the Thanatos Guild and was revived by Thea and Nyssa with a Lazarus Pit, which results in bloodlust that leads to him killing two innocent security guards. After Emiko's plan is thwarted, Harper leaves Star City to atone for killing two innocent people.
Harper is also featured in the season's flash-forwards, set in 2040, where William finds him in exile on Lian Yu. The two follow clues left by Felicity and return to Star City to regroup with local vigilantes against the threat of the Archer program and Galaxy One. After Galaxy One is defeated, the older vigilantes, Roy included, take the blame for what happened and leave Star City to live as fugitives.
The character is based on the DC Comics character Roy Harper.
Slade Wilson / DeathstrokeEdit
Slade Wilson (portrayed by Manu Bennett; main: season 2, recurring: season 1; guest: seasons 3, 5–6) is one of the world's deadliest assassins and mercenaries, a former Australian Secret Intelligence Service (ASIS) operative, and the mentor-turned-archenemy of Oliver Queen. He is the main antagonist of season two.
In season one flashbacks, Slade is a combat mentor to Oliver on Lian Yu and teaches him to fight Edward Fyers and his mercenaries in their attempts to escape the island and stop Fyers' plans. Though Slade openly doubts Oliver's abilities to survive or fight, often giving him demeaning nicknames, the two become close friends and fight together well. He also becomes romantically drawn to Shado.
In season two flashbacks, he is severely wounded by Dr. Ivo's mortar attacks and Oliver injects him with Mirakuru, a strength-enhancing serum left on the island in World War II by Japan, in order to save his life. When Shado is killed, Slade blames Oliver for her death and turns on him. In the present, Slade is alive, now operating as the mercenary "Deathstroke", and plots to destroy Starling City with an army of Mirakuru soldiers working with Sebastian Blood and Isabel Rochev. He undermines Oliver's life by causing him to lose his money and his business, revealing some of Oliver's secrets to Laurel and Thea and killing Moira before unleashing his army on the city. Oliver defeats him when Felicity injects him with the Mirakuru cure and he is imprisoned in an A.R.G.U.S. supermax prison on Lian Yu.
In season three, having been temporarily released by Malcolm Merlyn, Slade attempts to imprison Oliver and Thea in the supermax and return to Starling but the two are able to beat him.
In season five, Deathstroke appears in a hallucination created by the Dominators, where he serves as a countermeasure to prevent Oliver and his friends from escaping. Bennett did not portray the character in the episode. Bennett would later reprise the role for the final two episodes of the season, appearing in a cameo in "Missing" and appearing as a major character in the finale. By the time of the season five finale, Slade is revealed to have completely recovered from the effects of the Mirakuru and willingly helps Oliver in his quest to rescue his team and son from Adrian Chase. Slade's fate is unknown due to Lian Yu's destruction.
In season six, Slade, having survived the explosion, returns to Star City to see Oliver and thank him for giving him information about where to find his son.
The character is based on the DC Comics character Deathstroke.
Malcolm Merlyn / Dark ArcherEdit
Malcolm Merlyn (portrayed by John Barrowman; main: seasons 3–4; recurring: seasons 1–2, 5; guest: 7), born Arthur King, is a wealthy businessman, a member of the League of Assassins, the father of Tommy and Thea and one of the main antagonists of the series. During season one, Malcolm plots the Undertaking, the destruction of the Glades using an earthquake device, after his wife Rebecca was murdered there. When Robert Queen earlier threatened the Undertaking, Malcolm arranged to destroy Robert's ship, Queen's Gambit, resulting in Robert's death and indirectly leading to Oliver and Sara becoming the Arrow and the Canary. In the main story of season one, he uses Moira to gain access to the resources needed for the Undertaking. He tries to reshape Tommy into a better person by cutting him off which works but causes tensions between them. When the Arrow interferes with his plan, Malcolm becomes a vigilante called "Dark Archer" to oppose him and proves to be far more skilled. He suspects Oliver to be the Arrow and is proven right after defeating him a second time. In the season finale, Malcolm is seemingly killed by Oliver though he manages to destroy much of the Glades, inadvertently kills Tommy, and is publicly exposed for his crime by Moira.
In season two, Malcolm returns to suborn the jury in Moira's trial to find her innocent of the Undertaking. He discovers that he is Thea's biological father, following Adam Donner's discovery of Malcolm's affair with Moira. In an attempt to keep Malcolm from Thea, Moira informs Raʾs al Ghul of his survival, forcing Malcolm to flee Starling City. During Slade's attack on the city, Malcolm returns to save Thea from the Mirakuru soldiers and convinces her to leave Starling with him.
In season three, Malcolm is revealed to have trained Thea to be a warrior in Corto Maltese. Despite being both the League's target and a fugitive of the law, Malcolm secretly returns to Starling City, using personal wealth and resources following the loss of his company. Under an alias, Malcolm purchases the foundry from Queen Consolidated, the site of Thea's nightclub, Verdant. It is revealed that his name in the League of Assassins is "Al Sa-Her" (الساحر), which translates to "The Magician". He continues to train Thea until she can defeat him in combat. Malcolm plots the death of Raʾs to eliminate his blood debt, and manipulates Thea into killing Sara so that Oliver will take the fall for her murder and challenge Raʾs to a duel; this plan fails and almost gets Oliver killed. Malcolm learns that crime lord Danny Brickwell was responsible for the murder of his wife, but Oliver persuades him to choose justice over vengeance for Thea's sake, allowing Brickwell to be tried for his crimes. Malcolm trains Oliver in swordplay in preparation of battling Raʾs together. When Oliver tells Thea that Malcolm brainwashed her into killing Sara, she betrays Malcolm to the League; he is captured and tortured but freed from Nanda Parbat when Oliver takes the place of Raʾs. After Thea is killed by Raʾs, Malcolm accompanies Oliver to Nanda Parbat to revive her but Oliver is forced to join the League. Malcolm secretly works with Oliver to cripple the League from within and stop the plan of Raʾs to unleash the Alpha/Omega bio-weapon on Starling City. Malcolm leads Team Arrow to save the city until Oliver's return. After Raʾs is killed by Oliver in a final sword fight, he passes leadership of the League to Malcolm, which Nyssa suspects had been Malcolm's scheme all along. Despite their renewed animosity, both Malcolm and Oliver harbor deep respect for each other: Malcolm regards Oliver as a surrogate son and Oliver himself remembers the man Malcolm was before the death of his wife.
In season four, Malcolm helps Laurel resurrect Sara in order to settle his family's blood debt with Laurel, and helps Thea control her bloodlust. He provides information to Oliver and Barry Allen about Vandal Savage. To keep Darhk from learning Oliver's secret, Malcolm masquerades as Green Arrow. However, despite occasionally helping Oliver, Malcolm remains an amoral man and is despised by Oliver's team and their allies. Malcolm's aid to Oliver is either for protecting Thea or for his own agendas. Malcolm ultimately loses both his left hand and his power after Nyssa wins the League's leadership with Oliver's help, leading Malcolm to align himself with Darhk for revenge against Oliver. In the process, Malcolm reveals Oliver's secrets to Darhk. As a result, Darhk makes Malcolm a H.I.V.E. member and provides a cybernetic prosthesis. In order to protect himself and Thea from Damien's plans, Malcolm steals Damien's idol, working with Andy Diggle, which results in Laurel's death. Malcolm remains a leader to disbanded remnants of the League, and with them he forms its splinter faction the Thanatos Guild. Malcolm allies with Team Arrow again when Darhk tries to destroy the world without the means to survive it.
In season five, an illusion of Malcolm appears in the Dominators' dream world and opposes Oliver, Thea, John, Ray and Sara when they try to leave, but is swiftly killed by Thea. Malcolm appears in flashbacks working with Konstantin Kovar, giving him Sarin gas in exchange for the means to acquire information on Unidac Industries to build the earthquake device. Malcolm returns in the penultimate episode of season five, offering Oliver his assistance in saving his friends, most importantly Thea. After Malcolm frees Thea, Felicity, Curtis and Samantha, Thea accidentally steps on a landmine. As Captain Boomerang approaches them, Malcolm takes Thea's place, telling the others to run. As they run, the landmine is seen exploding in the distance, killing both Malcolm and Captain Boomerang.
In season seven, despite his death, Malcolm makes appearances on the second and third parts of the Arrowverse crossover "Elseworlds".
The character is based on the DC Comics character Merlyn.
Curtis Holt / Mister TerrificEdit
Curtis Holt (portrayed by Echo Kellum; main: seasons 5–7; recurring: season 4) is a technological savant, inventor, and bronze-medal-winning Olympic decathlete, who works with Felicity at Palmer Technologies. In season four, he helps her rescue Ray Palmer from Damien Darhk. He later learns Oliver's secret identity and helps them defeat Brie Larvan. He then helps Felicity and Noah shut down Rubicon to stop H.I.V.E.
He officially joins the team in season five as part of Oliver's efforts to expand and accept help after Diggle and Thea retired. While in the field, Curtis adopts a costume similar to his comic counterpart, including his 'Fair Play' jacket and T-shaped mask. He alternates between field work and tech support depending on the crisis, such as helping Felicity devise a means of translating the extraterrestrial technology during the Dominators' invasion. In the mid-season finale, "What We Leave Behind", Curtis is hospitalized after he is shot with a tuberculosis vaccine by Prometheus, aided by the treachery of apparent teammate Evelyn Sharp. Curtis's husband Paul leaves him after discovering his vigilante activities, and they eventually divorce. At the end of season five, Curtis' fate is unknown due to the destruction of Lian Yu caused by Adrian Chase.
In season six, Curtis has survived the explosion by taking shelter in the plane with the others and is working with the team using his upgraded T spheres and other tech. He is revealed, that after leaving Palmer Technologies last year, he started an online business, which prompts Felicity to propose partnership with him to form their own company. After Oliver's actions causes Curtis to leave Team Arrow, he forms a new team with Dinah and Rene, with the same goals as the original Team Arrow.
In season seven, Curtis works as part of A.R.G.U.S., but ultimately leaves the group following a disagreement over the decision to revive the Suicide Squad as the Ghost Initiative. He accepts a job in Washington, D.C. and leaves Star City. He later returns to take part in the operation to track down Emiko Queen and her biological weapon, before returning to D.C. to propose to his boyfriend.
The character is based on the DC Comics character Mister Terrific.
Adrian Chase / PrometheusEdit
Adrian Chase (portrayed by Josh Segarra; main: season 5; guest: season 6) is Star City's new district attorney in season five who helps Mayor Oliver Queen clean up the streets through the justice system. He is also Prometheus, a ruthless and mysterious hooded archer who kills, and has a grudge against Oliver Queen. He wears a black uniform almost identical to Oliver's first garb. Prometheus is aware of Oliver's identity, having deduced that the Green Arrow was the presumably-deceased Hood/Arrow, and begins a killing spree of innocent people with arrows and shurikens made from Oliver's discarded bolts. Prometheus has no tolerance for anyone else targeting Green Arrow and kills Tobias Church when the crime lord ignores a warning to leave Green Arrow alone. He also targets those close to Oliver by framing Quentin Lance, manipulating Evelyn Sharp into betraying Oliver, staging Billy Malone in his uniform to be killed by Oliver, and sends Black Siren (Laurel Lance's Earth-2 doppelgänger) to mess with Oliver. Chase was born as Simon Morrison, the illegitimate son of Justin Claybourne, a pharmaceutical owner on the List who was killed during Oliver's first year as The Hood. Seeking revenge against Oliver, he was taught by Talia al Ghul to gain a skillset to match Oliver's. However, Simon was never close to his father who realized that Simon is psychopathic and wanted nothing to do with him. After Simon and his allies kidnap Oliver's friends and family to Lian Yu, Oliver's party ultimately beats Simon's. Unwilling to accept defeat, Simon kills himself, detonating the bombs throughout the island in an attempt to kill Oliver's loved ones, successfully killing Samantha Clayton.
In season six, Morrison returns as one of Oliver's hallucinations while drugged by Vertigo.
On why Simon is not Vigilante, as in the comics, Guggenheim stated,
We knew we were going to do Vigilante this year, we knew who the character of Prometheus was, we knew that the character of Prometheus was the son of one of Oliver's early kills in season one, we knew that he was going to be someone who was going to indoctrinate himself into Oliver's good graces in the mayor's office and eventually betray him. One morning... it occurred to me that if we called this character Adrian Chase, and we made him a district attorney, everyone would be so focused on when he becomes Vigilante that they wouldn't be expecting that he really was Prometheus.
Laurel Lance / Black Siren / Black Canary (Earth-2)Edit
Dinah Laurel Lance (portrayed by Katie Cassidy;[a] main: 6–present; recurring: season 5), Following the death of the Earth-1 Laurel Lance in season four, an antagonistic version of the character from Earth-2 named Black Siren (also portrayed by Cassidy) is introduced. She eventually redeems herself and returns to Earth-2 as the heroic Black Canary. Like her doppelgänger, she was also romantically involved with the Oliver Queen of her Earth before his death. Originally appearing on The Flash, the character was promoted to series regular on Arrow from season six onwards.
The character is based on the DC Comics character Black Canary.
Rene Ramirez / Wild DogEdit
Rene Ramirez (portrayed by Rick Gonzalez; main: season 6–present; recurring: season 5) is a vigilante in Star City whose reckless and cocksure actions prompt the Green Arrow to guide him. His vigilante attire consists of normal clothes, with a hockey mask to hide his identity; the red dog image on the shirt of his uniform, leads to his gaining the moniker of "Wild Dog". Already trained as a soldier, Rene receives additional training from Oliver and becomes a skilled combatant. Prior to becoming a vigilante, Rene kills a criminal in defense of his family, which led to his wife's death during the altercation; his daughter Zoe was put in a foster care due to the community deeming him unfit as he succumbs to alcohol blackouts. With Curtis Holt's help, Rene seeks legal actions to get his daughter back. He later becomes Quentin Lance's assistant to help him reform Star City politically and they become friends.
Rene later becomes one of the main characters in season six, having survived the explosions on Lian Yu. He then becomes one of the main members of Team Arrow, and receives improved vigilante attire. However, after helping Team Arrow, Team Flash, Supergirl and the Legends save the multiverse from the invaders of Earth-X, Rene is cornered by FBI agent Samanda Watson, who knows about his secret identity as Wild Dog and forces Rene to testify against Oliver as the Green Arrow. If Rene refuses, he will never see his daughter again. When Rene confesses this to Oliver, Oliver kicks him off the team. But the entire team is soon brought back together, in order to rescue Quentin from Cayden James and Black Siren. After the team rescues Quentin, Rene is kicked off the team permanently for abandoning his primary mission. Because of this, Dinah and Curtis leave the team too, no longer trusting Oliver. Oliver later apologizes to the three, but while they accept his apology, they refuse to return to Team Arrow and form a team of their own called New Team Arrow. Later, when it is revealed that Ricardo Diaz is the true villain of season six after he kills James, Rene is coerced by Diaz into testifying against Oliver at his trial, with Diaz threatening the safety of Rene's daughter in front of him. However, Rene, despite Diaz's threat, supports Oliver along with the rest of Team Arrow. After the trial, Oliver is free to go, thanks to Christopher Chance posing as the judge, and finally makes peace with Rene. Later, during the final battle with Diaz and his organization, The Quadrant, Quentin gets shot and eventually dies of his wounds in hospital later that day. Rene becomes one of the many members of Team Arrow, who mourns Quentin's death. When Oliver is arrested by Watson and the FBI, and publicly announces his identity as the Green Arrow to the world, Rene continues to protect Star City in his honor.
In a flashforward to 2040, Rene has become the Mayor of the Glades.
The character is based on the DC Comics character Wild Dog.
Dinah Drake / Black CanaryEdit
Dinah Drake (portrayed by Juliana Harkavy; main: season 6–present; recurring: season 5) is a detective, formerly of the Central City Police Department. She went undercover in a drug ring with the alias "Tina Boland", only for her partner to be murdered after they were both revealed to be cops. After the particle accelerator explosion, she receives the ability to produce sonic waves with her scream and hunts down the leader of the drug ring to get revenge for her partner's death. Oliver and his team seek to recruit Drake as a candidate to succeed Laurel Lance as Black Canary. Dinah joined the Star City Police Department after she settled in the city.
Harkavy has been promoted to the main cast for season six, her character having survived the explosions on Lian Yu.
Following the battle on Lian Yu, Dinah is upgraded from a detective to police lieutenant. In flashbacks, Dinah was almost killed by Black Siren before being saved by Quentin. She later finds out that her former partner-lover, Vincent Sobel is alive and the Vigilante, She resumes her relationship with him before he is killed by Black Siren. She goes on a killing spree, targeting Black Siren and her allies. She is later fired from her job after Oliver fires the corrupt police captain, Kimberly Hill. Before leaving the desk, she fires Dinah and the rest of the honest cops. Dinah and Black Siren become allies when Quentin is shot by Ricardo Diaz.
In season seven, Dinah is once again part of the SCPD. She is outed as the Black Canary, when she uses her canary cry to save Mayor Pollard's life. When Dinah has her throat slit by Stanley Dover, she loses her ability to perform the canary cry. She is eventually given Sara Lance's old tech collar, which enables her to perform the cry again.
In a flashforward to 2040, Dinah is part of a vigilante resistance group called the Canary Network. After the defeat of Galaxy One, Dinah departs Star City, leaving Zoe Ramirez in charge of the Canary Network.
The character is based on the DC Comics character Black Canary.
Ricardo Diaz / DragonEdit
Ricardo Diaz (portrayed by Kirk Acevedo; main: season 7; recurring: season 6), when he first appears, is a drug lord, who leads a team street criminals and scientists in the development of an experimental steroid used by John Diggle to work around his tremors. He is later revealed to be the main antagonist of season six, who manipulates events of Oliver Queen and Cayden James' lives behind the scenes, and kills James upon admitting that he orchestrated his son's death and prepares to launch his own scheme upon Star City while getting its judges, politicians and police officers on his payroll. With help from Samanda Watson and the FBI, the politicians and police officers that are on Diaz's payroll are arrested. Diaz mortally wounds Quentin Lance, but manages to evade capture when he is knocked off a building by Black Siren and lands in water. Now in hiding from both the federal authorities and Oliver Queen's allies for his machinations, Diaz is vengeful towards Oliver for crippling his criminal empire.
In season seven, Diaz contacts some unnamed inmates inside Slabside Maximum Security Prison to make Oliver's time there miserable, while also targeting his wife Felicity outside of prison. Having hired new allies, the Longbow Hunters, Diaz gets his hands on a drug, which gives him super super-strength. He then targets Anatoly Knyazev for betraying him when he worked with Cayden James, but is captured by John Diggle, who is helped by an unidentified new Green Arrow (Emiko Queen). When Diaz is brought to Slabside Maximum Security Prison, he bribes himself free, takes control of the prison and releases all inmates from their cells in an attempt to get Oliver. With help from Bronze Tiger, Oliver subdues most of the inmates and finally beats Diaz in his cell.
Later, when A.R.G.U.S. discovers that a financier named Dante is behind multiple terrorist cells, including the Longbow Hunters, Diggle places Diaz in the Ghost Initiative and has an explosive placed in his neck in order to ensure his compliance in tracking him down. They successfully track down Dante, but during the mission to apprehend him, Diaz uses a defibrillator to short out his implant and exposes the set up to Dante. This leads to Dante killing the Deputy Director of A.R.G.U.S. and Princess Noor while escaping. Felicity confronts Diaz and holds him at gunpoint until Diggle knocks him out. Diaz is sent back to Slabside for going against his deal. While in his solitary cell, an unknown person floods his cell with gasoline from the sprinklers and then lights him on fire. Ben Turner reveals to Laurel Lance (Earth-2) that it was the new Green Arrow, who killed Diaz.
The character is based on the DC Comics character Richard Dragon.
Emiko Queen (portrayed by Sea Shimooka; main: season 7), also referred to as Emiko Adachi, is Robert Queen's illegitimate daughter and thus Oliver Queen's paternal half-sister. She is also revealed to be a main antagonist of the season seven's arc. When she and her mother are abandoned by Robert Queen, Emiko begins working as a courier for criminal organizations, through which she comes in contact with Dante, a member of the Ninth Circle. Dante takes Emiko under his wing and starts training her, but she still holds out hope for being able to reconnect with the Queens. However, Dante tells her to choose between her family and the Ninth Circle. When Robert is unwilling to acknowledge Emiko as his child and turns down her proposal for a company called Queen Materials, Emiko chooses not to give him information about the explosives planted onboard the Queen's Gambit before the voyage where it sank. Rising through the ranks, Emiko is secretly the leader of the Ninth Circle by the events of season seven.
She takes up the mantle of Green Arrow while Oliver Queen is incarcerated at Slabside Maximum Security Prison. Her mother, Kazumi Adachi, was mysteriously murdered at the Glades a year prior to Oliver's outing as Green Arrow. Being an accomplished gymnast and trained in combat by Dante, her skills and tactics match Oliver's. She initially had no intention to become a vigilante until her mother's murder. Needing a disguise, she chooses to have hers based on Oliver's after he reveals himself being the Green Arrow. Therefore, she has legitimate claims to the Green Arrow name based on abilities in addition to being a Queen. Parallel to Oliver's first year as the Hood, Emiko hunts down people on her list, later revealing that they are possible leads to her mother's killers. She also steals from them to help those in need. As Green Arrow, she helps in defeating Ricardo Diaz, which allows Oliver to be released from prison. Because of this, Oliver trusts his mysterious successor despite not knowing the archer's identity, and after he discovers his relation to her, he tries to connect to his half-sister. Rene Ramirez, who also trusts the archer due to her saving his daughter Zoe's life, serves as a liaison between her and Team Arrow, and later after he discovers her identity and senses that she needs a friend, offers her his friendship. Emiko's identity as Oliver's half-sister is revealed in the episode "Unmasked", when she visits their father's empty grave. She is determined to avenge her mother's death.
When Oliver resumes his role as the Green Arrow, Emiko adopts a new red outfit similar to her comic book counterpart's (and by extension her legal sister Thea's). The bond between Emiko and Oliver is broken in the episode "Inheritance", when her alliance with Dante and the Ninth Circle is revealed. Eventually, Oliver reveals to Emiko that Dante had her mother killed to manipulate her, which leads to her killing Dante. Emiko later reveals to Oliver that her goal is to destroy his legacy, forcing him to die as a villain. Emiko returns to occasionally using the Green Arrow outfit in an attempt to fool the SCPD into thinking that Oliver and his team are behind the terrorist threat facing Star City. Emiko's focus on her personal vendetta publicly exposes the Ninth Circle. This, combined with her failure to deliver on her promise to destroy Star City and her hesitation to finally kill Oliver, leads to the organization's council turning on her. Emiko and Oliver fight the Ninth Circle together until Emiko is mortally wounded by Ninth Circle member Beatrice. Emiko dies after making amends with Oliver and is buried under the name "Emiko Adachi Queen".
The character is based on the DC Comics character Emiko Queen.
Connor Hawke (portrayed by Joseph David-Jones; main: season 8; recurring: season 7) is the biological son of Ben Turner.

While Connor starts working together with Mia, with the two also sharing a romantic connection, he initially does not reveal his occupation or the fact that he knows her parentage. He has a strained relationship with his adoptive brother John Diggle, Jr., who has become the leader of a criminal Deathstroke gang.
The character is based on the DC Comics character Connor Hawke.
Mia Smoak / BlackstarEdit
Mia Smoak / Blackstar (portrayed primarily by Katherine McNamara); main: season 8; recurring: season 7) is the daughter of Oliver Queen and Felicity Smoak, born in 2019. Raised in secrecy away from Star City in Bloomfield, a neighborhood for former A.R.G.U.S. and DIA agents, she grew up without her father. Mia is an accomplished fighter due to being trained by Nyssa al Ghul throughout her childhood and into adulthood. After learning that her mother is still secretly operating as a vigilante, Mia runs away from home and goes to Star City, taking on the alias Blackstar. When she is first encountered in the 2040 flashforwards, Blackstar is a cagefighter, open about her resentment of vigilantes. Eventually she meets up with Dinah Drake, Roy Harper, Zoe Ramirez and her half-brother William, who are trying to find out what happened to Felicity. The two half-siblings, who previously did not know of each other, connect, and Mia asks William about what kind of a man their father was.

William first appears in season four as a teenager, portrayed by Jack Moore. He learns of his relation to Oliver and discovers his father's secret at the end of season five. In season six, William is living with Oliver after his mother Samantha is killed by Adrian Chase / Prometheus. While his faith in superheroes is shattered after Oliver's failure to his mother, he eventually bonds with him and begins seeing Felicity as a surrogate mother. She also inspires William into the fields of engineering and technology. In season seven, after becoming the target of criminals like Damien Darhk, Adrian Chase, Ricardo Diaz, and Stanley Dover, William chooses to go live with his grandparents in order to have a normal life away from the Green Arrow. Unbeknownst to him, his grandparents later sever all of his ties with his father and stepmother, leading him to believe that they have abandoned him.
In the 2040 flashforwards, William is a wealthy young adult and the owner of a company called Harris Consolidated, secretly funded by Felicity. He is also revealed as being gay. Following clues left by Felicity, William brings together a group of people that include his father's old associates Dinah Drake and Roy Harper, Zoe Ramirez and Mia Smoak, the secret daughter of Oliver and Felicity. The two half-siblings form a relationship and together with their allies set out to save Star City. William accepts his role in the mission, defying his stepmother's attempt to bench him.
