He is based on the DC Comics character of the same name. In season one, Oliver returns to Starling City after being presumed dead for five years, shipwrecked on the remote island of Lian Yu following the loss of his family yacht. He lives a dual life -- rich playboy by day and vigilante by night, targeting individuals whose names appear in a notebook given to him by his now - deceased father, Robert Queen. 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, and Sara Lance are aboard the Queen 's Gambit when bad weather causes it to sink. During the shipwreck, Sara is sucked out to sea. Oliver and his father escape on a life raft but Robert 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 discovers 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 realizes the list of names is connected to a larger conspiracy called `` The Undertaking '', a scheme orchestrated by Malcolm Merlyn to destroy the poor and crime - ridden neighborhood of the Glades. Oliver fights and supposedly kills Malcolm but The Undertaking succeeds, leaving the Glades largely destroyed and 503 dead including Tommy Merlyn. In season two, Oliver returns to Starling City after spending time at Lian Yu to work through his grief. 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-administers 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 Slade '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 business. Oliver gets help from Sara Lance, now the vigilante `` Canary '', and takes Thea 's boyfriend, Roy Harper, as a protégé. After Felicity injects Slade with the Mirakuru cure, Oliver defeats Slade and locks him in an underground prison on Lian Yu. In flashbacks, Oliver is hunted by Dr. Ivo 's armed crew who seek the Mirakuru and he accidentally causes the death of Shado, his lover on the island. Slade also loved Shado, which explains his vendetta against Oliver. A flashback before the shipwreck reveals that Oliver impregnated a college classmate 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 three, 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 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 Raʾs al Ghul due to Malcolm 's manipulations. During a fight with Raʾs, he suffers a mortal wound and nearly dies, but is saved by Maseo and Tatsu Yamashiro. Raʾs demands that Oliver become his heir because he is the only man to survive a death match against him, fulfilling a prophecy of the League of Assassins. When Oliver rejects the offer, Raʾs tries to force him by killing people while posing as the Arrow. When Raʾs nearly kills Thea, Oliver chooses to join the League, abandoning his former identity to become Al Sah - him ( Arabic : سهم ‎ ; `` Arrow '' ) ; he pretends to be a darker and crueler version of himself in order to get closer to Raʾs and destroy the League from within. Raʾs has Oliver marry his daughter, Nyssa al Ghul, to keep his bloodline in charge of the League. Oliver later kills Raʾs and inherits the mantle but immediately passes it to Malcolm. He decides to retire from being the Arrow and live 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, after witnessing his combat capabilities on the island, Amanda Waller forces him to become an A.R.G.U.S. agent 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 four, Oliver is called from retirement to help Laurel and Thea stop a group known as `` The Ghosts '' led by 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 Arrow, who Star City ( formerly Starling City ) believes to have died. He plans to propose to Felicity and run for mayor. While on a mission with Barry Allen in Central City, Oliver meets Samantha Clayton 's son, William, and ultimately learns that he is William 's father. Samantha refuses to grant Oliver full access because of his playboy past and her ill feelings toward his mother. The revelations of his fatherhood complicates Oliver 's relationship with Felicity and his duty as Green Arrow, and threatens to jeopardize his mayoral campaign. When a H.I.V.E. attack leaves Felicity permanently paraplegic, Oliver 's fight with Darhk becomes a vendetta. Oliver also discovers that Thea is dying because the Pit 's restorative effect on her is waning ; Nyssa offers a cure in exchange for killing Malcolm. In a fight, Oliver cuts off Malcolm 's left hand and gives the Demon 's Head ring to Nyssa in exchange for the cure. Nyssa disbands the League of Assassins, causing Malcolm to seek vengeance against Oliver. As a result, Darhk kidnaps William, Oliver 's relationship with Felicity becomes estranged, and Oliver is forced to resign from his mayoral campaign. After Darhk is successfully prosecuted, Malcolm, with help from Andy Diggle, aids Darhk 's escape by restoring his magic, and fatally stabs Laurel with Oliver 's arrow. Laurel dies of her injuries moments after admitting that she still loves Oliver, who is devastated. During his quest to stop Darhk, Oliver learns that the pure forces of light can counter Darhk 's powers and that H.I.V.E. plans to rule 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 five, Oliver initially returns to killing because he blames himself for Laurel 's death. 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. Oliver is stalked by a mysterious archer, Prometheus, who seeks vengeance for the death of his father by `` The Hood ''. The season 's flashbacks examine Oliver 's time in Russia, where he joins the Bratva ( Russian mafia ) as part of an assassination plot against Konstantin Kovar and explores the criminal fraternity in the process. One of Raʾs al Ghul 's children, Talia al Ghul, trains Oliver and gives him green garb based on the League of Assassin 's uniforms. In the present, Talia seeks vengeance against Oliver for killing her father and allies with Prometheus, who was another of her students. After a series of battles with Prometheus, leading to the abductions of Oliver 's family and friends, including Samantha and William, Oliver defeats his enemy at Lian Yu, though Prometheus kills himself afterward. William also learns of his relation to Oliver and discovers his father 's secrets. In season six, despite Oliver 's victory, the final battle with Prometheus resulted in Samantha 's death and Thea 's coma. Oliver now struggles to raise William himself, whom he has now acknowledged publicly of his relation to him. However, William blames his father for his mother 's death and keeping his distance from him. Oliver also tries to rekindle his romance with Felicity, and hopes that William would accept her. Oliver 's secrets are also at risk when a photo of him unmasked is leaked by an unknown party and is broadcast throughout the media, putting both his career and family in danger. Oliver later appoints Diggle to the Green Arrow mantle in order to be more spend more time with his son. But, after Diggle is injured on a mission, Oliver decides to temporary take up the Green Arrow mantle again until Diggle recovered. During the events of Crisis on Eartn X, Oliver encounters his Earth X doppelgänger, the Dark Arrow, and after the events, Oliver and Felicity officially marry each other. A villainous parallel universe doppelgänger of Oliver, Dark Arrow from Earth - X, is introduced in season six, during the crossover event `` Crisis on Earth - X ''. He is the Führer of the Nazi - ruled Earth and married to Overgirl, Supergirl 's doppelgänger. He is enemies with General Winn Schott ( Supergirl 's friend Winn Schott 's doppelgänger ), who is the resistance movement leader of the Freedom Fighters and heroes include Earth - X 's Guardian / James Olsen ( Supergirl 's friend James Olsen 's doppelgänger ), Citizen Cold / Leonard Snart ( Leonard Snart 's Earth - X 's doppelgänger ), and The Ray / Ray Terrill ( Earth - 1 's displaced superhero ). This Oliver is also the leader of Earth - X 's supervillain team New Reichsmen, in which his wife, Tommy Merlyn 's doppelgänger as Prometheus, and a time remnant version of Eobard Thawne, Barry Allen 's archenemy, are also members. During the final battle with the Green Arrow and his allies, though both archers are equally matched in skills, the Dark Arrow was later killed by Green Arrow after being distracted from his wife 's explosive death, giving Oliver the chance to fire an arrow into his doppelgänger 's chest. Laurel Lance / Black Canary / Black Siren Further information : Black Canary Katie Cassidy Dinah Laurel Lance ( portrayed by Katie Cassidy ) is an assistant district attorney and Oliver Queen 's ex-girlfriend. She is based on the DC Comics character of the same name. In season one, she is a lawyer for legal aid firm CNRI and Tommy Merlyn 's girlfriend. When Oliver returns, she blames him for the death of her sister, Sara. She gradually comes to accept him upon learning of his suffering on Lian Yu, and remembering her sister 's rebellious faults. This puts Laurel at odds with her father, Quentin. She occasionally works with the Hood / Arrow -- unaware that he is Oliver -- with cases the courts are unwilling to move on. 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 two, Laurel is hired as an assistant district attorney, assigned to prosecute Moira Queen. Because of guilt over Tommy 's death, she and Oliver decide to remain friends, and Laurel begins taking drugs and drinking while pushing friends and family away. Laurel eventually chooses sobriety after an argument with Oliver. Inspired by Sara 's vigilante alter - ego, Canary, she regains her job as assistant district attorney. Learning from Slade Wilson that Oliver is the Arrow, Laurel confronts Oliver and decides to keep his secret, also deducing Sara 's secret. In season three, Laurel works to prosecute the criminals Oliver catches. Sara returns to Starling City and is killed in front of Laurel, who makes an amateurish attempt to replace her as the Canary. Oliver refuses to train her, so Laurel seeks former boxer and vigilante Ted Grant / Wildcat 's help with combat training. Laurel does not tell Quentin about Sara 's death until a near - death experience, resulting in their estrangement. She wears Sara 's Canary jacket and eventually becomes the `` Black Canary '', partnering with Roy Harper. She learns that Malcolm is directly responsible for Sara 's murder and tries to avenge Sara and Tommy 's deaths. Nyssa saves her from Malcolm and furthers her training. Laurel gradually becomes a skilled combatant and Cisco Ramon provides 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 '', becomes her primary weapon used to disorient enemies with an overwhelming scream, while Team Arrow use ear - pieces to shield them from the effect. After Raʾs al Ghul 's defeat and Oliver 's retirement, Laurel remains on Team Arrow defending Starling City. In season four, Laurel and Thea realize they are outmatched against H.I.V.E. and they bring Oliver back. Laurel hopes to revive Sara in the same way Thea was resurrected ; with help from Oliver and John Constantine, Laurel retrieves Sara 's soul from the afterlife. Laurel discovers that Damien Darhk is extorting her father to work with H.I.V.E. Laurel is further frustrated at Oliver when she learns that he cheated on her, resulting in his having a son named William, but has no ill feelings towards William 's mother, Samantha. During Darhk 's attempted breakout, Laurel is stabbed with an arrow by Darhk as revenge against her father 's betrayal. She later dies after making Oliver keep a promise to not let her be the last Canary, and confessing that she still loves him. Evelyn Sharp begins masquerading as Black Canary ; her actions brand Black Canary as a criminal. Oliver saves Laurel 's image by revealing her secret to the public. Laurel is later avenged when Oliver kills Darhk. In season five, when Oliver, John, Thea, Sara, and Ray are abducted by the Dominators, they are placed in a shared hallucination where Laurel is alive ; seeing `` Laurel '' allows Oliver and Sara to move on from her death. In the mid-season finale, Oliver discovers Laurel seemingly alive and well, but Felicity discovers she is actually Laurel 's Earth - 2 counterpart -- Laurel Lance / `` Black Siren '', previously introduced in The Flash -- and is working with Prometheus. Oliver hopes to help this Laurel find redemption, believing it to be the only way to forgive himself for Earth - 1 Laurel 's death. This Laurel was in love with Oliver on Earth - 2, until his death 10 years ago ; she moved to Central City to start a new life, only to become Black Siren when affected by Harrison Wells ' particle accelerator, and then fell under Zoom 's influence. Encountering Earth - 2 Laurel also motivates Oliver to keep his promise to Earth - 1 Laurel. Earth - 2 Laurel works with Evelyn to kidnap the members of Team Arrow including Quentin. Laurel reveals to Quentin that, while she helps Adrian out of gratitude for freeing her from A.R.G.U.S., she is sentimental towards him as he is her father 's Earth - 1 counterpart. After the destruction of Lian Yu at the end of the season, Laurel 's fate is unknown. In season six, the Earth - 2 Laurel survived the Lian Yu explosions but was injured by Quentin and left for dead, but a mysterious figure subsequently found and rescued her from the island. Actress Katie Cassidy is again be a series regular during season six, portraying Laurel Lance / Black Siren, after appearing as the character in four guest appearances in season five. Tommy Merlyn Colin Donnell Thomas `` Tommy '' Merlyn ( portrayed by Colin Donnell ) is Oliver 's best friend and the son of Malcolm Merlyn. He shares his surname with the DC Comics character Merlyn. A version of Tommy was introduced as a former friend - turned - enemy of the titular character in the Green Arrow comics in The New 52. In season one, Tommy is a spoiled playboy who lives off the financial support of his father. After his father 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 relationship becomes strained with Tommy seeing Oliver as a killer. Tommy later breaks up with Laurel thinking that she belongs with Oliver. Tommy is killed rescuing Laurel from a collapsing building damaged by Malcolm 's earthquake machine during the Undertaking. In season two, Oliver vows never to kill again in Tommy 's memory. During Oliver 's fight with Cyrus Gold, he sees an image of Tommy, who calls him a hero and urges him to defeat his enemy. It is also revealed that he is the paternal half - brother of Thea Queen. In season three, Tommy appears twice in flashbacks. In `` Sara '', he travels to Hong Kong looking for Oliver, but fails to find him. In `` The Return '', the episode shows him throwing himself a birthday party, trying to stop Thea from using drugs, and growing closer to Laurel. In season five, Tommy appears as a ghost in the Dominators 's dream world as Oliver leaves it. In season six, Earth - X 's version of Tommy Merlyn is revealed to be Earth - X 's version of Prometheus, introduced in Supergirl. Like his doppelgänger, he is friends with the Oliver Queen of his world, who is Dark Arrow. Merlyn is a member of the New Reichsmen with Dark Arrow, Overgirl, and the Reverse - Flash, and his parents are alive on Earth - X. After Sara Lance and Alex Danvers capture him, Merlyn cruelly taunts Oliver over his attachment to his deceased doppelgänger, and kills himself via cyanide capsule, leading Oliver later sees Tommy 's doppelgänger as a perversion to him. John Diggle / Spartan David Ramsey John Thomas Diggle, Sr., ( portrayed by David Ramsey ) is a decorated former United States Army Special Forces soldier, honorably discharged with the rank of master sergeant, and Oliver 's friend and partner. 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. During season one, John is hired as Oliver 's bodyguard and becomes his confidant in his mission to save Starling City. John tries to help Oliver balance his normal life and vigilante life, and occasionally helps him in the field. John provides Oliver with medical assistance, limiting his need for hospital treatment. Already a skilled fighter, John receives additional training from Oliver. John has a grudge against Floyd Lawton / Deadshot who killed his brother, Andy. John dates his brother 's widow, Carly, and is a father figure to her son, A.J., during this season. In season two, John and Felicity continue to help Oliver with his crusade and John continues to be Oliver 's adviser and field partner, along with Sara and Roy. John has a relationship with his ex-wife Lyla Michaels, is an unofficial member of A.R.G.U.S., and is a member of the Suicide Squad under the codename `` Freelancer ''. He also develops an uneasy alliance with Amanda Waller who occasionally asks him for field assistance with A.R.G.U.S. missions. It is revealed that Lyla is pregnant with John 's child. In season three, John continues to help Oliver and his team, but has to devote more of his time to his new baby with Lyla, whom he names Sara after Sara Lance is killed. After Lyla is seriously injured in an attack, they decide to remarry. When Oliver is presumed dead at Raʾs al Ghul 's hands, John leads Felicity, Roy, and Laurel until his friend 's return. After Oliver 's return, John accompanies him to Nanda Parbat to help him free Malcolm, but the two are captured. John and Lyla marry after a near - death experience with the Suicide Squad, when Deadshot sacrifices himself for them. John and Lyla decide to quit Team Arrow and A.R.G.U.S. for their daughter 's sake. After Oliver leaves the team to join the League of Assassins as part of a deal to revive a deceased Thea, John becomes the team leader, though he is not yet ready to forgive Oliver for kidnapping Lyla as part of a deception to gain acceptance by the League. In season four, John, going by the codename `` Spartan '', discovers that the organization that targets Star City is H.I.V.E., who have hired Lawton to murder John 's brother, Andy. John eventually forgives Oliver after their fight with a H.I.V.E. metahuman operative named Jeremy Tell. With Quentin Lance 's help, John learns that Damien Darhk had Andy murdered, and that he was a drug cartel leader and Darhk 's territorial rival prior to his death. However, John discovers that Darhk actually faked Andy 's death and recruited him as a H.I.V.E. soldier, leading John and his brother to become enemies. Guilt - ridden over his brother 's role in causing Laurel 's death, John seeks revenge against Andy and Darhk. John kills his brother after Andy nearly causes Lyla and Sara to be killed. He initially lies to Lyla, saying that he killed Andy in self - defense, but Oliver encourages John to admit the truth to his wife. John rejoins the US Army after confiding to his wife and Darhk 's defeat. In season five, John is betrayed by his commanding officer, J.G. Walker, following a failed attempt to sell nuclear weapons. John is framed for Walker 's crimes ; Oliver and Lyla break him out of state prison, and John stays at H.I.V.E. 's former base until his innocence can be proven. John remains guilty about killing Andy and continues to serve as Spartan to redeem himself. Due to the events of The Flash episode `` Flashpoint '', John 's family history is altered : his daughter Sara has been erased from existence and replaced by John `` J.J. '' Diggle, Jr., as a result of a timeline change caused by Eobard Thawne, correcting the Flashpoint reality created by Barry. John eventually learns of the alteration of his life, his daughter 's erasure and his son 's status as a time aberration, and despite the hurt caused by these circumstances, he chooses to forgive Barry. Lyla, however, distrusts and possibly hates Barry for this. Felicity is able to prove John 's innocence by restoring the digital files that Walker had destroyed. However, Andy 's betrayal and death at John 's hands has taken a toll on him ; he struggles to control his rage and occasionally pulverizes criminals to vent it, fueling Oliver 's concern over his erratic behavior. John later befriends Oliver 's chosen successor to Laurel 's mantle, Dinah Drake, a Central City detective, and encourages her to set down roots in Star City. By the end of season five, John 's fate is unknown due to the destruction of Lian Yu caused by Adrian Chase. In season six, John is revealed to have survived the explosion by taking shelter in the plane like the others. However, he was wounded by bomb shrapnel and suffers a degenerative nerve injury that affects his motor control that requires taking daily medications, resulting him to develop a drug dependency. When Oliver decides to retire from being the Green Arrow, he appoints John as his successor, not knowing that John is not in condition to remain in action until later. Oliver returns to vigilantism until John is fully recovered from his injury. Thea Queen / Speedy Main article : Thea Queen Willa Holland Thea Dearden Queen ( portrayed by Willa Holland ) 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. 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. In season one, 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 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 of her wealth, Roy later begins to genuinely fall in love with her. In season two, 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 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 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 three, Thea is in Corto Maltese receiving combat training from Malcolm, though she soon decides to return to Starling with Oliver. She 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 knew Oliver 's secret. After Thea is told that her father used her as a pawn against both Oliver and Raʾs al Ghul by drugging and manipulating her into killing Sara Lance, she arranges for him to be captured by the League in retaliation. She reconciles with Roy but is nearly killed by Raʾs and brought back to life in the Lazarus Pit in exchange for Oliver joining the League of Assassins. 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.
