The series premiered on October 10, 2012, in the United States on The CW television network, and is currently in its fifth season. On January 8, 2017, The CW announced that Arrow would be renewed for a sixth season.
Arrow follows the story of billionaire playboy Oliver Queen (Stephen Amell). He is discovered after being stranded for five years on an isolated island. When he returns home, Queen secretly becomes a bow and arrow wielding vigilante in order to honor his father's legacy and atone for his family's sins.

The characters that eventually aid Queen's vigilante efforts include: former soldier John Diggle (David Ramsey), I.T. expert and skilled hacker Felicity Smoak (Emily Bett Rickards), former assassin Sara Lance / Black Canary (Caity Lotz), aspiring vigilante Roy Harper (Colton Haynes), his sister Thea / Speedy (Willa Holland), and attorney-turned-vigilante Laurel Lance (Katie Cassidy). The group also receives support from Quentin Lance (Paul Blackthorne) who works at the police department. 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.
The following is a list of characters that have appeared on the television series.
|Oliver Queen / Green Arrow||Stephen Amell||1–present||–||–|
Oliver Jonas "Ollie" Queen is the main protagonist of the series. He is based on the DC Comics character of the same name.
In season 1, Oliver returns to Starling City after being presumed dead for five years. He was shipwrecked on a remote island (Lian Yu) following the loss of his family yacht. He returns to Starling City to begin a crusade as a hooded vigilante. He targets citizens of Starling, whose names appear in a notebook given to him by his father before his death.
He lives a dual life — rich playboy by day and vigilante by night. He struggles to find a balance between his quest and reconnecting with his family (his sister Thea Queen and mother Moira Queen) and friends (best friend Tommy Merlyn and ex-girlfriend Laurel Lance).
In flashbacks set five years earlier, Oliver, Robert Queen, and Sara Lance are aboard the Queen’s Gambit when bad weather causes it to sink. During the ship wreck, Sara is sucked out to sea. Oliver and his father escape on a life raft. While on board the life raft, Robert, his father, shoots himself to increase Oliver’s chances of survival, asking Oliver to "right his wrongs". Oliver eventually lands the raft on an island called Lian Yu. He soon realizes that he is not alone on the island as he is hunted by a mercenary group. With the help of allies, Slade Wilson, Yao Fei, and Shado he begins to learn the skills needed to survive.
During season one, John Diggle and Felicity Smoak both become involved in his crusade. The vigilante team ultimately realize the list of names is connected to a larger conspiracy that threatens the city called "The Undertaking". It is a scheme orchestrated by Malcolm Merlyn to destroy a poor and crime-ridden section of Starling City called the Glades. Oliver confronts and supposedly kills Malcolm in an attempt to stop the plot. The Undertaking eventually succeeds leaving the Glades largely destroyed and thousands dead (among them Tommy Merlyn).
In season 2, a grief-stricken Oliver Queen has retreated back to Lian Yu. He returns to Starling City to reignite his crusade. He now goes by the alias "Arrow", and in honor of Tommy, vows never to kill again. He fights criminals who take advantage of the Glades after its destruction, while trying to redeem himself as a hero, but is challenged when those closest to him are endangered. He co-runs Queen Consolidated with Isabel Rochev and becomes friends with Alderman Sebastian Blood. Oliver finds himself investigating a larger plot orchestrated by Slade Wilson, involving Mirakuru, a strength-enhancing drug. It is Wilson's intention to destroy everything and everyone Oliver cares for. Sebastian and Isabel are also working for Slade and help bankrupt Oliver, causing him to lose his home and his business. Oliver gets help from Sara Lance, now the vigilante "Canary", and he takes Roy Harper, Thea's boyfriend, as a protégé. After Felicity injects Slade with the Mirakuru cure, Oliver defeats Slade and locks him up in an underground prison on Lian Yu. In flashbacks, Oliver is hunted by Dr. Ivo's armed crew seeking the Mirakuru and he accidentally causes the death of Shado, his lover on the island. Slade also loved Shado, which explains his motives in the present. A flashback before the island reveals that Oliver impregnated a girl named Samantha Clayton, and Moira paid Samantha to tell Oliver the child died and to move to Central City, leaving him unaware of his impending fatherhood.
In season 3, Oliver has become a public hero to the citizens of Starling City and has taken Roy on as a full sidekick. He lives in his foundry safe house having lost his mansion. Oliver is faced with the moral question of whether he can be Oliver Queen and live his life while the city needs the Arrow. This is only further challenged when he realizes he is in love with Felicity. She has caught the attention of Ray Palmer, the new head of Queen Consolidated. After Thea returns to Starling City, they decide to reopen their nightclub together. Oliver is also inadvertently embroiled in a conflict with Ra's al Ghul due to Malcolm's manipulations. During a fight with Ra's, he suffers a mortal wound and nearly dies, but is saved by Maseo and Tatsu Yamashiro. Ra's demands that Oliver becomes his heir because he is the only man who has survived a death match against him. According to the League‘s prophecy, only the man who survives his assault would succeed Ra's. When he rejects the offer, Ra's begins killing people in Starling City posing as the Arrow in order to force Oliver to accept his offer. When Ra's nearly kills Thea, Oliver chooses to join the League, abandoning his former identity to become Al Sah-him (Arabic: سهم; "Arrow") and pretends to be a darker and more cruel version of himself in order to get closer to Ra's to bring the organization down from the inside. Ra's has Oliver marry his daughter, Nyssa al Ghul, to keep his bloodline in charge of the League. Oliver later kills Ra's and inherits the mantle but immediately passes it to Malcolm. He decides to retire from being the Arrow and live a happy life with Felicity, knowing that Laurel, Diggle, Ray, and Thea will protect the city in his absence. The season flashbacks explore Oliver's time in Hong Kong, where Amanda Waller forces him to become an A.R.G.U.S. agent after witnessing his combat capabilities on the island using the Yamashiros as his handlers. It is revealed that Oliver returned to Starling City while on a mission where he discovered Thea's drug problems, witnessed the start of the relationship between Laurel and Tommy, and saw Felicity two years before they eventually met.
In season 4, Oliver's retirement is short-lived as Laurel and Thea ask for his assistance in stopping a group known as "The Ghosts" who have been wreaking havoc in Star (formerly Starling) City. He agrees to help, knowing the leader of the Ghosts is Damien Darhk, leader of H.I.V.E. Oliver now goes by the name "Green Arrow", ostensibly a new vigilante following in the footsteps of the former Arrow, who Star City believes to have died. He also plans to propose to Felicity and run for mayor. Oliver also has an associate connection with John Constantine. While on a mission with Barry Allen in Central City, by chance Oliver meets a boy, William, in a coffee shop and discovers that he is Samantha Clayton's son. Oliver ultimately learns that he is William's father after he has Barry run a paternity test. Despite his desire to acknowledge William, Samantha refuses to grant Oliver full access; she sees Oliver as troubled due to his past as a playboy, and she still hates his mother. The revelations of his fatherhood, and the fact his mother kept it a secret from him, not only complicates his relationship with Felicity and his duty as Green Arrow, but also threatens to jeopardize his mayoral campaign. After an attack by H.I.V.E leaves Felicity permanently paraplegic, Oliver becomes vengeful and as a result, his fight with Darhk becomes a vendetta. Oliver also discovers that Thea is dying after learning the Pit's restorative effect on her is waning, leaving him to search desperately for a cure for his sister until Nyssa offers one in exchange for killing Malcolm. Oliver and Malcolm fight. Oliver cuts off Malcolm's left hand and gives the Demon's Head ring to Nyssa in exchange for the cure. Instead of Nyssa remaining leader of the League of Assassins, she disbands it, causing Malcolm to seek vengeance against Oliver, making them enemies once again. As a result, Darhk kidnaps William, his relationship with Felicity becomes estranged, and he is forced to resign from his campaign following his enemies' discovery of his son. After Darhk is successfully prosecuted, Malcolm, with help from Andy Diggle, helps him to escape by restoring his magic, and fatally stabs Laurel with Oliver's own arrow while he is helpless to stop it. Laurel later dies of her injuries moments after admitting that she still loves him leaving Oliver devastated and broken. During his quest to stop Darhk, Oliver learns that the pure forces of light can counter Darhk's powers due to those endowments deriving from the forces of darkness and H.I.V.E.'s plan of ruling a post-apocalyptic world. At the end of the season Oliver stops Darhk's plan to destroy the world and kills him. With the death of the previous mayor, Ruve Adams, Oliver becomes acting mayor of Star City. The season's flashbacks explore Oliver's training with A.R.G.U.S. and his infiltration of the Shadowspire organization on Lian Yu.
In season 5, Oliver initially returns to killing due to blaming himself for Laurel's death as he felt he could prevent it. He later recruits a team of vigilantes to help balance his double life as Green Arrow and Star City's mayor. In the process, he meets metahuman vigilante Dinah Drake, and sees her as a candidate to succeed Laurel as Black Canary, inspired to continue Laurel's legacy after encountering her evil Earth-2 counterpart.. He is also stalked by a mysterious archer, Prometheus, who has some troublesome link to his past and who is vengeful towards him for having killed his father during his time as "The Hood". The season's flashbacks explore Oliver's time in Russia, where he joins the Bratva as part of an assassination plot against Konstantin Kovar and explores the criminal fraternity in the process. There, he encounters an elite member of the League of Assassins and one of Ra's al Ghul's children, Talia al Ghul. He is being trained by her and she gives him green garb based on the League's members' uniforms, before he eventually returns to Lian Yu. In the present however it is revealed that Talia also seeks vengeance against Oliver for killing her father and thus allies with Prometheus who she is revealed to have trained also.
|Laurel Lance / Black Canary / Black Siren||Katie Cassidy||1–4; 6||5||–|
Dinah Laurel Lance is an assistant district attorney and Oliver Queen's ex-girlfriend. In season 1, she is a lawyer for CNRI, a legal aid firm, and Tommy Merlyn's girlfriend. She had been Oliver's girlfriend prior he was shipwrecked. When he returns, she despises him for having an affair with her sister Sara which apparently led to her death. She gradually comes to accept him upon learning of his suffering on the island, and remembering her sister's rebellious faults. This puts Laurel at odds with her father Quentin who blames Oliver for Sara's death, though Laurel acknowledges Sara's indirect role in her own death. She also occasionally works with the Hood/Arrow—unaware that he is Oliver—with cases the courts are unwilling to move on. After Thea is involved in a drug-related incident, Laurel prevents her from going to prison by giving her community service at CNRI. She sees Thea is following the path Sara did and hopes to detour her away from it, while working to become close friends. Oliver and Laurel eventually rekindle their relationship after Tommy breaks up with her. Tommy dies saving Laurel when CNRI is destroyed along with much of the Glades.
In season 2, Laurel is hired as an assistant district attorney and is assigned to help prosecute Moira Queen. But she and Oliver, because of guilt over Tommy's death, decide not to pursue their relationship and remain friends. She has also become depressed over Tommy's death and starts taking drugs and drinking, and pushing her friends and family away. She is attracted to Alderman Sebastian Blood but discovers he has ties to criminal Cyrus Gold and suspects he may also be a criminal; she is proven right. Laurel eventually chooses sobriety after an argument with Oliver. Inspired by her returned sister Sara's vigilante alter-ego Canary, she gets back her job with the district attorney's office. She learns from Slade Wilson that Oliver is the Arrow. Slade hopes to use her as a pawn against Oliver, but instead Laurel confronts Oliver with this knowledge and decides to keep his secret, and also quickly deduces Sara's secret. After Slade's defeat Sara returns to the league but leaves Laurel her Canary jacket.
In season 3, Laurel is working to prosecute the criminals Oliver catches. She also worries over her father's continuing field activities while he continues to recover from his injury from Slade's attack. She urges him to use his new political powers to serve the city. When Sara returns again to Starling City, she is killed in front of Laurel. Grief-stricken and vengeful, Laurel makes a disastrous and amateurish attempt to replace her late sister as the Canary. Oliver refuses to train her, so Laurel seeks former boxer/vigilante Ted Grant/Wildcat's help with combat training. However, Laurel fears for Quentin's well being and initially does not tell him about Sara's death until a near-death experience. She confesses her secret resulting in Quentin and Laurel's estrangement for some time. She also wears Sara's Canary jacket in remembrance of her, and eventually becomes the "Black Canary". In her new role as a vigilante, she partners with Roy Harper to help liberate the Glades from crime lord Danny Brickwell during Oliver's absence, ultimately working outside the law while remaining a prosecuting attorney. She eventually learns that Malcolm Merlyn is directly responsible for Sara's murder. She tries to avenge both Sara's and Tommy's deaths. Brickwell overpowers her but she is saved by Nyssa, who ultimately offers to help Laurel further her training. Gradually she becomes a skilled combatant with familiarity with the League of Assassins' tactics. In addition, Cisco Ramon helps Laurel by providing her with an ultrasonic collar using components from both Sara's and Hartley Rathaway’s weapons, improving Laurel's tactics with sonic weaponry. This collar, dubbed the "Canary Cry" by Cisco, becomes her primary weapon used to disorientate enemies with an overwhelming scream, while Team Arrow utilizes specialized ear-pieces so Laurel's scream does not affect them. After Ra's al Ghul's defeat and Oliver's retirement, Laurel remains on Team Arrow defending Starling City.
In season 4, when H.I.V.E. attacks the city, Laurel and Thea bring Oliver back to help after realizing they are outmatched. After Laurel learns the details of Thea's resurrection after Ra's attack, she hopes to bring Sara back in the same way, but her sister remains without a soul after the resurrection. However, with Oliver and John Constantine's help, Laurel retrieves Sara's soul from the afterlife, and later, with Cisco's help, she refines Sara's costumed persona as the White Canary. Laurel discovers that Damien Darhk is extorting her father to work with H.I.V.E. Her fight against Darhk becomes personal. Laurel is further frustrated at Oliver when she learns that he cheated on her prior to his affair with Sara, resulting in him having a son named William but has no ill feelings towards William's mother Samantha. After Darhk is sent to prison he attempts to escape. During the breakout, while fighting alongside her team, Laurel is stabbed with an arrow by Damien, as revenge upon her father for betrayal. She later dies after making Oliver keep an unknown promise, and confessing that she still loves him. When Evelyn Sharp begins masquerading as Black Canary to avenge her family, her actions brand Black Canary as a criminal. But Oliver saves Laurel's image by revealing her secret to the public. Her identity as Black Canary is engraved on her gravestone. She is later avenged when Oliver kills Damien.
In season 5, Laurel's promise is revealed to be a request to Oliver to not let her be the last Canary. When Oliver, John, Thea, Sara, and Ray are abducted by the Dominators they are placed into a shared hallucination where Laurel is alive. However the five realize the dream is not real and leave, but seeing "Laurel" allows Oliver and Sara to move on. In the mid-season finale, Oliver discovers Laurel seemingly alive and well, but Felicity discovers she is actually her Earth-2 counterpart Laurel Lance / Black Siren, previously introduced in The Flash, unwillingly working with Prometheus. Though she is defeated and taken in A.R.G.U.S.' custody, Oliver hopes one day to help this Laurel find redemption. This Laurel also was in love with Oliver on Earth-2, until his death 10 years ago and she moved to Central City to start a new life, only to became Black Siren when affected by Harrison Wells' particle accelerator. Encountering Earth-2 Laurel also motivates Oliver to keep his promise to Earth-1 Laurel, and he recruits Dinah Drake, a former detective from the Central City Police Department and metahuman vigilante with the same power as Earth-2 Laurel, to succeed as Black Canary. Earth-2 Laurel will appear in the final two episodes of the season.

In season 1, Thea is battling a drug and alcohol problem which she used to fill the pain of losing her brother. After court ordered community service from taking "Vertigo", she grows to be more responsible. Thea's addiction with Vertigo also causes a bitter animosity between Oliver's vigilante alter-ego and the drug's creator, The Count. She also falls in love with Roy Harper, a lifelong street criminal who she meets when he steals her purse. Though he initially has no romantic interest in Thea despite an obvious physical attraction to her, mainly out of resentment because of her wealth, Roy later begins to genuinely fall in love with her.
In season 2, Thea runs the Verdant nightclub in Oliver and Tommy's absences and continues seeing Roy, but is frustrated by Roy's need to save people, though she gradually comes to accept it. She is however the subject of exclusion as most characters keep secrets from her including her true paternity which she eventually discovers when Slade Wilson abducts her. She then breaks up with Roy when he cheats on her, though he only does this to keep her away from him during his Mirakuru problem. Despite reconciling with Roy after having learned of his illness, she breaks up with him again after discovering his allegiance to the Arrow. After her mother's death, she decides to leave Starling City. Malcolm comes to save her and convinces her to leave with him.
In season 3, Thea begins the season in Corto Maltese receiving combat training from Malcolm, though she soon decides to return to Starling with Oliver. She also reopens her nightclub after Malcolm secretly buys the foundry from Queen Consolidated for her. She learns Oliver's secret identity as the Arrow when he shows her his hideout under the nightclub and begins to distrust Malcolm after learning that he already knows about Oliver's secret. After Thea is told that her father used her as a pawn against both Oliver and Ra's al Ghul by drugging and manipulating her into killing Sara Lance, she arranges for him to be captured by the League in retaliation.

Thea blames herself for letting her brother join the League. Roy breaks up with her when he leaves Starling City after faking his death, hoping that Thea can make a life of her own without him. He also leaves her his red costume which she wears to become a vigilante herself as his successor.
In season 4, Thea works with Oliver and his friends in the fight against the terrorist organization H.I.V.E. as "Speedy". Despite the enjoyment of being a vigilante, Thea's behavior has become increasingly volatile and reckless when in the field, which Oliver realizes is a side effect of being in the Lazarus Pit. In addition, Thea helps Laurel to bring Sara back from the death in hopes of making amends towards the Lance family. Because of this, Thea is telepathically linked with Sara after her resurrection upon the Lazarus Pit. It is also revealed that Thea's Lazarus Pit side effect is able to counterattack Damien Darhk's life force drain in addition relieving her bloodlust temporarily. Thea is dying as the result of the Pit's restorative effect waning. With Tatsu Yamashiro's help, Nyssa al Ghul gives Oliver the 'Lotus', an elixir used by the Crescent Order that permanently reverses the effects of the Lazarus Pit, saving her life. Damien Darhk's wife, Ruvé Adams, eventually brainwashes Thea's new boyfriend Alex Davis into kidnapping her to a miniaturized H.I.V.E. facility built from stolen technology belonging to Oliver's ally Ray Palmer.
In season 5, Thea now works as Oliver's chief-of-staff, and is adamant about retiring from being a vigilante after Oliver kills a number of Tobias Church's thugs. She hires Quentin to be Deputy Mayor to Oliver and helps him beat his alcoholism. However, working to help her brother politically causes Thea at risk of taking her mother's immoral path; she ruined Oliver's new love interest Susan Williams' career as a reporter for a time but Felicity is able to rectify her mistake. She resigns from her position afterward. She would occasionally resume her vigilante role when needed.
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 one of Green Arrow's sidekicks in the comics.
|Moira Queen||Susanna Thompson||1–2||–||3, 5|
Moira Queen 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.

In season 3, Thompson returned to the series to record Moira's voice for when Oliver calls home from Hong Kong.
In season 4, it is later revealed that Samantha never cashed Moira's check, and the attempted bribe resulted in Samantha hating the Queens; as the result, Samantha denied Moira access to her grandson, William, when she was alive, leaving Oliver hurt when he finds out but he is unable to acknowledge his son due to his mother's actions.

In season 3, Quentin has survived, albeit now with frequent chest pains, and has been promoted to captain, a power he uses to call off the anti-vigilante task force. However his frequent assistance to the Arrow in the field continues to strain his condition and forces him to rely on the political connections of his new position and his subordinates to continue serving the city. He is initially unaware of Sara's death as Laurel believed that telling him would cause him a heart attack, but he becomes suspicious after Sara's protégée, Sin, informs him that the woman in Sara's costume is not her. He ultimately learns the truth about Sara's death and that Laurel has become her vigilante successor, and becomes estranged from Laurel and again succumbing to his alcoholism.

In season 4, it is revealed that Quentin is forced to be in league with Damien Darhk and his organization, H.I.V E., after Darhk threaten Quentin with the lives of his family's. After Oliver discovers his secret alliance, he persuades Lance to play double agent for him while continue working with Darhk, so he can inform what Darhk is really up to. However, in the process, Quentin exposes himself and thus Darhk gradually becomes suspicious of him but is too late to stop Quentin from learning that an ancient artifact in his possession is to be a source of his supernatural powers. With Quentin's intel, Mari McCabe is able to destroy Darhk's mystical idol, leaving Darhk powerless and arrested by Quentin's subordinates. Quentin then publicly admits in court of his association with H.I.V.E. under Darhk's duress, determined to see that justice will be served but also endangering his career. He reconciles with Laurel, and reunites with Sara once more after Laurel, Oliver, and John Constantine bring her back from the dead. He begins seeing Felicity's mother Donna Smoak, whom Quentin is happy to be with and thus starts to move on from his divorce and alcoholism, and he receives Laurel's blessing of his new relationship after she finds out. Quentin eventually meets Felicity's father and Donna's former husband, Noah Kuttler, and he personally arrest Noah after Felicity turns her father in. After Darhk murders Laurel, Quentin seeks to bring her back the same way as she did for Sara, only to learn from Nyssa al Ghul that the Lazarus Pit has been destroyed shortly after Sara's return, leaving him unable to resurrect his eldest daughter and devastated. With Donna's support, Quentin is able to cope with his loss without succumbing to alcoholism as he did after Sara's deaths. After saving the city with Oliver, Quentin is fired from his department, and he decides to leave Star City in hopes to lead a new life with Donna.
By Season 5, 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 working to reform Star City's police force as a deputy mayor and working with the Green Arrow to reduce the city's rising crime rate. Quentin also revealed to have formed the Anti-Crime Unit to combat serious crimes prior to his dismissal from the SCPD, and would lead them under his new position when needed but also puts him at odds with his former colleagues. However, after Evelyn Sharp's fight with Prometheus, Felicity discovers that the shurikens the latter used was made from Oliver's old arrow heads stolen by someone who has access to the police department's evidence facility, and Quentin finds cuts on him that are identical as the killer's, implicating him and causing doubts of his sanity. He eventually learns that Adrian Chase is Prometheus and responsible for the attempted framing. Thea eventually convinces Quentin to seek help at rehab after realizing how much Laurel's death is affecting him but Thea leaves the position of deputy mayor open for when he recovers. After resuming his position, Quentin befriends one of Oliver's protégés Rene Ramirez, after he learns his past encounter with him as a juvenile when he was a beat officer, and offers him a job as his assistant. He also befriends Oliver's chosen successor to the Black Canary mantle Dinah Drake. While Dinah expresses her hesitance to accept Laurel's mantle Quentin gives Dinah his blessing knowing it's what Laurel would want.
The character is based on the DC Comics character Larry Lance, husband to Dinah Drake Lance and father to Dinah Laurel Lance.

During the season 1 flashbacks, Slade is a combat mentor to Oliver on the island and teaches him most of his fighting skills to fight Edward Fyers and his mercenaries in their combined 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.

|Malcolm Merlyn / Dark Archer||John Barrowman||3–4||1-2||5|
Malcolm Merlyn, born Arthur King, is a wealthy businessman, member of the League of Assassins, father of Tommy and Thea and one of the main antagonists of the series. During season 1, Malcolm plots the Undertaking, the destruction of the Glades, after his wife Rebecca was murdered there. When Robert Queen threatened the Undertaking, Malcolm arranged to destroy Robert's ship, Queen's Gambit, resulting in Robert Queen's death and the assumed deaths of Oliver and Sara which indirectly lead to their journeys of becoming the Arrow and the Canary. In the present day, he uses Moira to gain access to all the resources needed and tries to reshape his son into a better person by cutting him off which works but causes tensions between them. When the Arrow interferes with his plan, Malcolm also becomes a vigilante called Dark Archer who similarly uses a bow and arrow but with a black costume to oppose him and proves to be far more skilled than him. He also suspects Oliver to be the Arrow and is ultimately proven right after defeating him a second time. In the season finale, he is seemingly killed by Oliver though he manages to destroy much of the Glades and inadvertently kills Tommy, and is also publicly exposed for his crime by Moira.
In season 2, Malcolm returns alive and in secret to suborn the jury in Moira's trial to find her innocent of the Undertaking. He discovers that he is Thea's biological father after following Adam Donner's investigation of Malcolm's affair with Moira. In an attempt to keep Malcolm from Thea, Moira informs Ra's 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 3, 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 returns to Starling City, though his presence and survival is not known to the general public. Despite the loss of his company, he still has his wealth and maintains various resources. Under an alias, Malcolm purchased 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" (Arabic: الساحر), which translates to "The Magician", after Malcolm performed a magic trick for a young Nyssa al Ghul upon his arrival in Nanda Parbat. He also continues to train Thea to the point where she can even defeat him in combat. Malcolm plots to rid himself of Ra's al Ghul and drugs Thea into killing Sara so Oliver will take the fall for her murder and challenge Ra's to a duel, as al Ghul's death will eliminate Malcolm's blood debt. However this plan fails and almost gets Oliver killed, who barely survives his fight with al Ghul and returns only after a whole month. 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 Brick to be tried for his crimes. Malcolm is tasked to train Oliver in swordplay following the latter's return in preparation of them battling Ra's al Ghul together. When Oliver tells Thea that she killed Sara, and that Malcolm is directly responsible because he brainwashed her to do it, she betrays Malcolm to the League; he is captured, taken to Nanda Parbat, and tortured but is freed when Oliver accept his offer to take Ra's place. After Thea is killed by Ra's, Malcolm accompanies Oliver to Nanda Parbat to revive her but Oliver is forced to take Ra's offer and join the League. However Malcolm secretly begins working with Oliver, planning to cripple the league from within and stop Ra's plan to unleash the Alpha/Omega bio-weapon on Starling City. Malcolm subsequently leads Team Arrow to save the city until Oliver's return. After Ra's is killed by Oliver in a final sword fight, he hands the leadership of the League to Malcolm, which Nyssa suspects is what Malcolm has schemed all along since Sara's death though he claims he only desired to rid himself of Ra's. Despite their renewed animosity following Ra's defeat, 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, though is unable to forgive him for everything that he has done.
In season 4, Malcolm helps Laurel resurrect Sara in order to have his family's blood debt with Laurel's settled, and helps Thea in controlling her bloodlust. He provides information to Oliver and Barry Allen about Vandal Savage. To keep Damien Darhk from figuring out Oliver's secret, Malcolm occasionally masquerades himself as Green Arrow. However, despite occasionally helping Oliver, Malcolm remains an amoral man and is despised by Oliver's team and their allies, particularly Barry Allen despite having no personal history with Malcolm. His aiding to Oliver is either for protecting Thea from Oliver's enemies or 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 him to align himself with Darhk for revenge against Oliver. In the process, Malcolm reveals Oliver's secrets to Darhk. As a result, Damien makes Malcolm a H.I.V.E. member and providing him a cybernetic prosthesis for his lost appendage. In order to protect himself and Thea from Damien's plans Malcolm steals Damien's idol back, working with Andy Diggle, which results in Laurel's death. Despite the League's disbandment, Malcolm remains a leader to its remnants. When Damien's shelter to survive his plan to end the world in nuclear fire is destroyed and his wife killed, Malcolm allies with Team Arrow again when Damien tries to destroy the world without the means to survive it.
In season 5, an illusion of Malcolm appears in the Dominators dream world and opposes Oliver, Thea, John, Ray and Sara while trying to leave but is swiftly killed by Thea. Malcolm appears in the flashbacks working with Konstantin Kovar to obtain bio-weapons.
He is based on the DC Comics character of the same birth name.
|Curtis Holt / Mister Terrific||Echo Kellum||5–present||4||–|

|Adrian Chase / Prometheus||Josh Segarra||5–present||–||–|
Adrian Chase is the new Star City district attorney who helps Oliver Queen as mayor clean up the streets through the legal system. Chase is also Prometheus, a ruthless and mysterious hooded archer who kills, and has a grudge against Oliver Queen/Green Arrow. He wears a black uniform almost identical to the Green Arrow's. Prometheus is aware of Oliver's identity, having deduced that the Green Arrow was the presumably-deceased Hood/Arrow and thus Roy Harper's deception, and begins a killing spree of innocent people whose names form anagrams on the List 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 he ignores his previous warning to leave Green Arrow alone, desiring to kill Green Arrow himself. He also targets those close to Oliver by framing Quentin Lance, manipulating Evelyn Sharp into betraying Oliver, staging Billy Malone in his uniform so Oliver unintentionally kills him and then sends Laurel Lance's interdimensional doppelgänger Black Siren to tarnish Oliver's memories of her. Prometheus is implied, although not directly confirmed, to be the illegitimate son of Justin Claybourne, a pharmaceutical owner on the List who was killed by Oliver during his first year as the Hood and apparently now seeks retribution against Oliver for his father's death. It is eventually revealed that Adrian's birth name is Simon Morrison, and was taught by Talia al Ghul to gain the skillset to match Oliver's.
On why Chase 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 1, 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."

He is also the father of Nyssa al Ghul. Ra's has never acknowledged Sara as a member of the League and disapproves of Nyssa's relationship with her. In order to protect Thea, Oliver lies that he killed Sara Lance and challenges Ra's to a trial by combat. Ra's easily defeats and nearly kills him by stabbing him through the chest. Ra's wants to make Oliver his heir—the new Ra's al Ghul, because Oliver is the only man to survive a death match against Ra's (and, according to the League's prophecy, only the one who survives Ra's blade is destined to become his successor). Ra's become fixated with Oliver, considering him as the one foretold by the prophecy who would take his place in the League, and neglecting other candidates (including Nyssa, who should be her father’s heir by familial bond); Ra’s estranges with his daughter as the result. When Oliver refuses his offer, Ra's orders the League to kill the people of Starling City, to get Oliver to accept. Ra's stabs Thea and leaves her near death, with a cure via the Lazarus Pit only available if Oliver agrees to become his heir. Oliver finally accedes, and Ra's names him "Al Sah-Him".
