Team Arrow, coined by Roy Harper and Felicity Smoak  and nicknamed "Justice League" by Alena Whitlock , is a vigilante team dedicated to ending crime in Star City created by Oliver Queen. When Oliver returned from Lian Yu, he began his activities as a vigilante in Star City on his own. However, after both John Diggle and Oliver were shot by Floyd Lawton and his mother Moira respectively, Oliver expanded his inner circle to include John and Felicity. The team has since grown to have had multiple members and allies in its time.
They operate from a base nicknamed the Arrowcave by Cisco Ramon, which was originally located under Verdant, a nightclub owned by Oliver and then run by his sister Thea, but is now currently set underneath Oliver's old mayoral campaign office.
During Oliver's time in incarceration, vigilantism was banned in Star City, and as such, the team remained mostly inactive. After Oliver’s release, he became deputized by the Star City Police Department. After the Chimera Incident, the rest of the team were also deputized. They were later made into their own "vigilante task force" while still maintaining their authority. Rene Ramirez coined their current situation as "the black ops unit of the SCPD".  The team was ultimately disbanded for a final time after the death of Emiko Adachi and the Ninth Circle's defeat.
The team generally followed Oliver's wishes and targeted those on "The List". However, they also occasionally focus on other criminals. They fight against crime/corruption, doling out justice when regular law enforcers cannot perform it on the perpetrators.
Following the destruction of the Glades, their secondary objective of catching unruly criminals has become their primary focus. They no longer rely on "The List" to direct them to criminal elements, and instead try to make a difference in the city in the aftermath of the destruction caused by the earthquake device. For a time, the team's goal was to eliminate the upsurge in extreme terrorist threats, such as Slade Wilson, the League of Assassins or Damien Darhk's Ghosts, but with Star City in a chaotic state after so many of these attacks focused on the city's elected government, Oliver decided to seek a role that would allow him to make a difference on the streets and in politics by running for and winning the position of Star City's mayor.
Year One: Becoming the Hood/The Undertaking
Oliver Queen initially worked on his one-man war against the people on "the List" alone, though this changes after he saved John Diggle from a bullet laced with curare. Oliver chooses to reveal his secret identity to John, who inevitably joins up when he realizes that Oliver needs someone to remind him of what he is fighting for.
After developing a strong connection with Helena Bertinelli, Oliver tells her his secret and trains her in non-lethal ways of taking people down. However, Helena was more interested in revenge and left, correctly assuming that Oliver wouldn't allow her to do things her way if she stayed.
When Oliver's mother Moira shoots him while he tried to interrogate her in his vigilante suit, Oliver seeks aid from Felicity Smoak, whom he had already relied several times when he encountered technological problems he could not face on his own. Oliver initially strove to keep Felicity out of his one-man war, feeding her ridiculously outrageous stories whenever he needed her help (which she accepted rather than believed). After she fulfills her promise to take him to the Arrowcave and helps John save his life following the revelation that he was the vigilante, Felicity joins the team in order to find her boss and Oliver's step-father, Walter.
John later leaves the team after Oliver chooses to pursue a fleeing criminal Laurel was prosecuting over helping John capture (or kill) the elusive sharp-shooter Floyd Lawton, who was responsible for the death of John's brother, Andy Diggle. John returns after Oliver apologizes to him, just in time to help try and prevent The Undertaking.
After they failed to prevent the Undertaking - albeit because they only managed to disarm one of the earthquake machines being used rather than both, limiting the damage caused without preventing it completely - the team initially disbanded, as Oliver went into self-imposed exile back on Lian Yu.
Year Two: Becoming the Arrow/Deathstroke's revenge
However, Felicity (and perhaps John) restored the Arrowcave at some point, and they later tracked Oliver down to convince him to return to Starling City. Agreeing to return, both to the city and his self-assigned duty as the vigilante, Oliver decided to shift their mission from crossing names off The List to attempting to clean up the chaos in the city caused by the Undertaking. He vows that he would no longer kill his enemies, wishing to honor his late best friend, Tommy Merlyn. To this end, he has enlisted the aid of Roy Harper as an informant, with Roy using his street contacts to get information that none of them can find on their own. Roy, however, remains unaware of both The Arrow's true identity and the identities of The Arrow's partners.
When Oliver is left for dead and drugged by Cyrus Gold, a member of Sebastian Blood's Church of Blood, Felicity makes the decision to involve Central City Police Department CSI intern Barry Allen in order to save Oliver's life. John knocks out and abducts Barry from the train station and brings him to the Arrowcave at Felicity's behest. Barry wakes up to find John standing over an unconscious Oliver in full Arrow garb, and Felicity asks for his help in saving him. Barry does so, only for Oliver to wake up and become infuriated with Felicity's actions. Oliver eventually calms down and accepts Barry's knowledge and promise to keep quiet, and Barry creates a mask for Oliver to wear before departing for Central City.
After Oliver found out from Thea, that Roy put someone in the hospital, Oliver offered to train Roy, so he can control his new powers and abilities, later Roy finds out that Oliver is The Arrow, after this, Roy officially becomes a member of the team, Roy is now aware of the identities of Oliver's partners.
Year Three: Death of the Canary/Fighting the League of Assassins
After saving Starling City from Slade's assault, Oliver (as the Arrow) is viewed as a hero to the citizens of Starling City, so much so that Quentin Lance calls off the Anti-Vigilante Task Force, shortly after this occurs, Sara Lance is killed by an unknown individual and Oliver and his team tries for months to find out the identity of Sara's killer with no success. Ra's al Ghul, leader of the League of Assassins, who is also adamant to punish the one responsible for Sara's death, loses his patience with Oliver, giving him and his team an ultimatum; that they are to identify Sara's killer within 48 hours or the League will kill 50 people per day until the person responsible for her murder reveals himself/herself.
Eventually, it is discovered that Malcolm Merlyn was indeed behind Sara's murder, albeit indirectly and that she was actually killed by Thea, whilst she was under the influence of Vitura, (a mind-control drug and memory-loss agent) which had been administered to her by Malcolm, Oliver was reluctant for her to take the blame for Malcolm's actions because even if he were to tell Ra's that Thea was under the influence of Vitura, Ra's would still kill Thea for being the one who directly killed Sara. Oliver faces Ra's in battle and loses, but he still manages to survive in the fight and because he had survived Ra's' blade - Ra's wants him to become his successor. Oliver politely declines and so Ra's and the league, pose as the Arrow and start killing people in Starling City with the Arrow's tools to frame him in a perverted attempt to make the offer more convincing.
After Roy took the blame for being the Arrow and faked his death to exonerate Oliver, Ra's attacked Thea and mortally wounded her, in order to finally force Oliver to accept his offer to become his successor. Ra's sends Maseo Yamashiro to give Oliver a message, that he can save his half-sister's life with the Lazarus Pit, only if Oliver agrees to finally become his successor and a member of the League, which Oliver reluctantly agrees to. Once Thea is saved - Oliver remains true to his word and leaves his team.
Thea joins the team when Oliver was about to kill Diggle and Thea shoots an arrow through Oliver's wrist. Although Ra's apparently successfully brainwashed Oliver to become his successor as he ordered him to destroy Starling City with a virus, Oliver's brainwashing was revealed to be a deception, as he had developed a vaccine for this virus based on his blood due to his exposure to the virus during his five years away from Starling City.
After Barry Allen extracted his team, they were able to shut down Ra's attempts to disperse the virus, followed by Oliver killing Ra's in a duel. With this success and the compromise of his identity, Oliver decided to retire as the Arrow to make a new life with Felicity.
Year Four: Becoming Green Arrow/War against H.I.V.E.
Oliver and Felicity returned however due to the attacks on the city made by the "Ghosts." Oliver found that the team had been capable of handling things on their own without his leadership when he gave out orders, but recognizing that they required his skills, he adopted the new persona of 'Green Arrow', taking a more public role than in his past role as the Arrow. After Jeremy Tell destroyed their lair while attacking Felicity and Curtis Holt, as well as Curtis knowing about the secret lair's elevator, Cisco Ramon and S.T.A.R. Labs renovated Sebastian's lair into a new headquarters for Team Arrow.
Faced with the new threat of Damien Darhk, Oliver decided to step up his efforts to be a hero as both Oliver Queen and the Green Arrow, acting against Darhk as the Green Arrow while running for the currently-vacant position of Star City mayor as Oliver Queen. As well as investigating Darhk, Oliver also found himself rescuing other heroes, such as retrieving Ray Palmer from Darhk's custody after learning that Palmer's suit had acquired the ability to shrink to microscopic size, resurrecting Sara Lance with the aid of John Constantine, or working with Barry to save Carter Hall and Kendra Saunders from psychotic immortal Vandal Savage.
However, despite the team's initial successes, their personal lives began to suffer when Felicity was paralyzed from the waist down in an attack by Darhk. Shortly after this, Thea faced death due to a side-effect of her treatment in the Lazarus Pit, forcing Oliver to confront Malcolm Merlyn in a duel and cut off his hand so that Nyssa could regain control of the League of Assassins and provide Thea with the cure. In revenge for Oliver's actions against him, Malcolm revealed the existence of Oliver's son William to Darhk, and although the subsequent campaign saw them destroy the source of Darhk's mystical power with the aid of Vixen, the revelation that Oliver had kept the fact that he had a son secret from her prompted Felicity to break off their engagement and leave the team, while Darhk's earlier blackmail forced Oliver to step down from the mayoral race so that Darhk's wife could run unopposed. However, after a prison riot saw Damien Darhk escape custody and kill Laurel Lance, Felicity returned to the team to put Darhk down once and for all.
After H.I.V.E.'s rampage through Star City, while attempting to execute Operation Genesis, Darhk was finally killed by Green Arrow. Soon after Darhk's death, Diggle, Thea, and Quentin left Team Arrow to evaluate their lives as they feared the lengths they had been forced to resort to during this conflict, leaving Oliver and Felicity on the team as Oliver officially assumed the role of mayor after the loss of all other candidates.
Year Five: New recruits/Battle with Prometheus
After the exit of most of his old team, sans Felicity, Oliver attempted to act on his own, refusing the help of others. However, after the insistence of Felicity, Oliver decided to try and recruit Evelyn Sharp and Rene Ramirez/Wild Dog, as well as begin training Curtis Holt. Refusing to reveal his identity, he brought them to a building to train, by working together to ring a bell, to no avail. Felicity suggested that Oliver utilize them as security for the AmerTek free clinic, which he eventually agreed to, instructing them not to interfere. However, after Wild Dog interfered, despite gaining some evidence, Oliver yelled at them, causing all three to quit. That night, Oliver went on a solo mission to stop "Ragman." Convincing him to not hunt down Janet Carroll, he also convinced him to join him in his vigilantism. The following day, Oliver called back his three previous recruits, revealing his identity in the hopes of gaining their trust. Having gained their trust, they rejoined the team.
It was later revealed that Evelyn seemed to be working with Prometheus and gives him information about the team. It was unknown where she was when Team Arrow joined the Legends, Team Flash and Supergirl to fight the Dominators.
Weeks later, the team celebrates Christmas which is interrupted by Curtis being attacked by Prometheus. The team tracks him down to an abandoned building where Evelyn reveals her allegiance with Prometheus and takes off with him. Prometheus later kidnaps Felicity's boyfriend Billy Malone and gets Oliver to go after him. Oliver is tricked by him to kill Billy by putting Billy in his suit and putting a voice chip on him. Felicity is devastated by his death but does not blame Oliver knowing it was Prometheus who did this, Curtis' husband Paul leaves him due to him not bearing Curtis' actions as a vigilante and John is recaptured by the police. Oliver is briefly distracted when he finds Laurel alive and well in his lair, but Felicity's research soon reveals that this Laurel is actually Laurel's counterpart from Earth-Two, forcing Oliver to defeat and capture her.
Following this, Oliver decides to find a new Black Canary to replace Laurel. The team finds Dinah Drake who gained the ability of sonic scream due to Particle accelerator explosion. After defeating Sean Sonus and Oliver revealing his identity. She agrees to join the team with Quentin giving his blessing to her becoming the new Black Canary.
The team later went to Russia to help John take down Walker and to stop his nuclear bomb test with the help of Anatoly. Rory leaves the team following the destruction of his rag suit. After Russia Star City is targeted by James Edlund when he starts a shooting spree across the city starting with City Hall due to them proposing a gun control act. The team manages to take him down and imprison him.
The ACU later issued an arrest warrant for Oliver due to him killing Billy Malone by Prometheus' trick. The ACU attack him but he manages to escape. He and the police make a cover-up of the murder. The team takes down Chien Na Wei, Carrie Cutter, and Liza Warner, when they escape from a prison transfer and the ACU helps them apprehend them. Prometheus reveals the cover-up and it threatens Oliver with impeachment. Oliver is forced to put an arrest warrant for the Green Arrow. While John, Curtis, Dinah, and Rene battle Vigilante when he targets Oliver and they manage to defeat them. Oliver learns Adrian Chase is Prometheus from Talia al Ghul and Adrian kidnaps Susan Williams to lure Oliver into a trap. The team manages to rescue and uses Chase's wife to convince him to stop his reign of terror. But Adrian kills her and he captures Oliver with the help from Talia. He later tortures him with the help of Evelyn.
When Oliver is let go by Adrian, he decides to stop being the Green Arrow and disband the team. But the team manages to change his mind and with the help of Helix, they expose Adrian being Prometheus, but he manages to get away. He almost kills Oliver and Felicity by blowing up part of the lair and trapping them. But they manage to get out. The team later battles Adrian again during which Oliver reveals that his father Justin Claybourne was going to disown him causing him to be apprehended. But Adrian has Laurel, Evelyn, and Talia kidnap all members except Oliver and brought them to Lian Yu. Following this, Oliver tries to move Chase to another prison but Chase reveals that not only has Team Arrow hostage but also William and William's mother Samantha as revenge for putting his wife into the conflict and gets on a helicopter to the island. Oliver forms an alliance with Malcolm and Nyssa al Ghul to rescue them. Upon arriving on the island, Oliver recruits Slade Wilson and Digger Harkness to their cause. But upon finding several members of his team Oliver was ambushed by Talia and Evelyn with Digger revealing Chase had recruited before Oliver's arrival on the island. Slade and Oliver managed to fight them off with Evelyn being captured. Olver told Malcolm Merlyn to get Felicity, Thea, Curtis, and Samantha to the plane Chase used to get them to the island. Oliver, Nyssa, and Slade split off from them to find the others.
On their way to the plane, Thea stepped on a landmine and Digger along with several of Talia's men began to approach them. Malcolm willingly took Thea's place on the landmine and urged the others to flee, they did and Digger caught up to Malcolm. He asked why Malcolm was just standing out in the open and Malcolm replied "Let me show you." stepping off the landmine causing a huge explosion that presumably killed Malcolm, Digger and Talia's, men. Much to Thea's dismay. Meanwhile, Oliver, Nyssa, and Slade arrived at the monastery where Chase had the rest of the team. Nyssa split off from the group and Slade knocked Oliver out, handing him over to Black Siren whom Chase had broken out of prison earlier. Oliver was taken to where the remaining members of the team were being held.
Felicity, Thea, Curtis, and Samantha managed to make it to the plane. However they soon discovered an explosive near them, Felicity used her tablet and discovered that there were hundreds planted all over the island and linked to a single trigger. Back at the temple, Oliver handed Dinah a collar Curtis made that her to control her powers but would also bypass the technology inhibiting her powers. She used it and the others were able to break free of the chains holding them. Talia overheard this and went to stop them from escaping but was stopped by the arrival of her sister, Nyssa. After a short conversation about their father, the sisters engaged each other in combat, with Slade arriving mid-battle to kill Talia's men present for the fight. Nyssa managed to beat Talia but spared her by knocking her out. They regrouped with Oliver and the others and attempted to leave the monastery but were intercepted by Chase, Black Siren and what remained of Talia's cult. Both teams began fighting each other with Black Siren and Dinah splitting off to fight each other. Black Siren ultimately came out on top by was knocked out by Quentin. Talia's men were soon killed and Chase himself was beaten by Oliver. Chase again tried to get Oliver to kill him by saying he killed William Clayton but Oliver still refused to kill Chase and become the person Chase believed he was.
Felicity contacted Oliver, revealing that the explosives were linked to Chase's heartbeat, he dies the explosives planted all over the island detonate. Chase then escaped from the monastery, Oliver told John to get the rest of the team to the plane and off the island. Oliver began to pursue Chase to retrieve his son from him. He found him at the docks attempting to escape on a boat, which Oliver jumped onto and engaged Chase in another fight. Oliver won this fight. Felicity contacted Oliver again to reveal Chase had sabotaged the plane, Oliver told her to have Slade guide them to an A.R.G.U.S. supply ship on the other side of the island. Chase then revealed he had William on the boat and placed him in a headlock, threatening to kill him or he would kill William. Oliver, however, managed to shoot Chase in the leg, causing him to let go of William who rushed into Oliver's arms. Chase remarked that it was good that they now had each other since it was going to be lonely without Felicity or Samantha. Chase pulled a gun out and shot himself in the head, detonating the explosives on Lian Yu. Oliver and William could only look on in horror at the island's destruction.
Year Six: The Outsiders/Ricardo Diaz's corruption
Despite Chase's belief, the team was mostly able to survive by taking shelter in a downed airplane that protected them from the worst of the explosive damage. However, Samantha died of her injuries and Thea was left in a coma that she had not recovered from after several months, and Laurel Lance was also revealed to have survived the attack. Some months later, despite the threat posed by Laurel, the threat of an FBI investigation into his dual identity as Green Arrow and his need to be a father to William prompted Oliver to stand down as the Green Arrow, passing the mantle on to John in his place. John attempted to hide the fact that he had suffered minor nerve damage in the battle on Lian Yu that had compromised his ability to aim, initially treating this with experimental steroid variants until the team was forced to destroy his supplier's operation. John was eventually injured stopping a bomb threat by Laurel and her new ally, hacker Cayden James, prompting Oliver to step back into the role of Green Arrow until his friend was ready.
Oliver later discovered that Rene was a witness in Samanda Watson's case against him when Samanda blackmailed Rene with the threat of never seeing his daughter again. The new Team Arrow fell apart after Oliver kicked Rene off the team for a second time for insubordination during the rescue mission for Quentin, effectively breaking Oliver's trust twice, while Curtis and Dinah, affronted by having their privacy invaded by the team's surveillance, also left.
Oliver discovers that Cayden has a criminal cabal, but he is unwilling to allow Rene, Curtis, and Dinah back into the team, due to his ego and wounded pride, as he only allows John and Felicity to update his former teammates of their situation; regarding his run-in with Cayden's criminal cabal.
But after Oliver's second run-in with Cayden's criminal cabal, he finally apologizes to Rene, Curtis, and Dinah for his role in the animosity that has developed between them, and also tries to get them to return to the team. Despite the sincerity of his apology, they all refuse, as they are unable to be part of a team that cannot trust them or treats them as equals. However, after discovering that Dinah tried to kill Laurel in cold blood; Oliver, John, and Felicity become distrustful of their former teammates once again; this time they have good reason not to trust them.
Determined to have revenge on Laurel for the murder of her boyfriend, Vincent Sobel, Dinah convinces Curtis to use John's arm implant to track the team to where they are hiding Laurel, fully aware of the physical pain and potential damage this will cause. Eventually, Team Arrow and the Outsiders get into a physical (violent/brutal) confrontation with each other. During the confrontation, Rene fires at Thea and Quentin, nearly hitting Felicity, who puts herself between them and Rene. The team's intervention allows Laurel to escape, but Rene is inadvertently injured by Oliver in the process (although it is very likely that Oliver didn't intentionally mean to put him in critical condition). After this confrontation, Team Arrow's friendship and alliance with the Outsiders have ended on bad terms; due to the fact that their former teammates (except for Rene) have crossed several moral lines. When Dinah later offers temporary assistance to Oliver to rescue Roy Harper from Ricardo Diaz, he states he can not go out in the field with someone he does not trust. Nyssa al Ghul arrives to warn the team about Athena and the Thanatos Guild, where they learn that Malcolm Merlyn had discovered more Lazarus pits which prompted Thea to leave and right his wrongs along with Nyssa and Roy.
John eventually lost faith in Oliver's leadership, stating that even when there are better alternative courses of action to take in a situation, but Oliver always does things his way. John points out Oliver's flaws/mistakes; including the death of Vincent Sobel, spying on his former teammates, etc., the argument eventually results in the two getting into a violent physical confrontation with each other; when Oliver says that at least his trail of bodies doesn't include his own brother. The fight is quickly broken up by Felicity, with both men soon apologizing to each other for attacking one another.
After a successful mission to destroy Ricardo Diaz's vertigo production facility, John tells Oliver that while he has become a better man since becoming a vigilante, his split focus between being a vigilante, mayor, and a father has caused him to become a bad leader. John also states that Oliver being Green Arrow allows him to be the best version of himself, and despite a tearful attempt to convince him otherwise by Felicity, John sadly leaves the team in order to become the best version of himself, which he feels he can't do with Oliver around.
Felicity left the team so Oliver can have more time focusing on taking down Diaz. When Oliver's trial was moved up a week earlier, he (secretly) contacted Christopher Chance to help exonerate the latter of being Green Arrow, during his trial, drop down from the roof of the skylight into the courtroom well in the Green Arrow suit to cast reasonable doubt about Oliver's secret identity, much to Oliver's surprise, Chance has disguised himself as the latter's late best friend, Tommy Merlyn.
The plan almost backfired, when Laurel Lance (who had acquired information regarding Christopher Chance; from Cayden James who was spying on Team Arrow from a heated bug that Laurel had planted in the Arrowcave months ago) was put on the stand to testify against Oliver, mainly due to being threatened by Diaz to do so, however, much to Oliver's surprise, she states to the entire court that Tommy is Green Arrow, not Oliver.
Rene anticipated that judge C. McGarvey may be under Diaz's payroll (which later turns out to be true) with the help of John, they knock him out and Chance takes his place, acquitting Oliver of all charges of being a vigilante.
After Oliver thanks Rene for everything he did for him, he also apologizes for his past unjust actions against the latter (that resulted in Rene refusing to return to the team) Rene (genuinely) excepts all of his apology and the two reconcile, Oliver also reconciles with his other teammates as well, such as Dinah, Curtis and John, as they all return to Team Arrow to help Oliver in his fight against Diaz, Felicity also returns to the team as well.
After realizing that Team Arrow is not only overwhelmed, but also outnumbered as well, as Diaz has an army under his command, Oliver (reluctantly) goes to Samanda Watson, who he (rightfully) despises for good reason, as he needs her help, however, Samanda only agrees to help Oliver if he agrees to her conditions; he is to admit that he is Green Arrow and he is to the publicly confesses to being a vigilante, which he agrees to without hesitation.
During his second confrontation with Diaz, Oliver used a device that Felicity made on his wrist to copy all of Diaz's files, that contain a list of every person under his payroll, and gave it to Samanda; destroying the crime Lord's corruption and control over Star City.
However, Team Arrow's victory against Diaz is not without a price, as Quentin was killed by Diaz while saving Earth-2 Laurel, much to the team's devastation.
As part of the agreement, every member of Team Arrow (except for Oliver) have been granted immunity; regarding their status as vigilantes, Oliver also doesn't go back on his word, as he does publicly confesses to being Green Arrow; after which, he sent to Slabside Maximum Security Prison for life. Following Diaz's downfall, and Oliver's (wrongful) incarceration respectively, John leaves the team to return to A.R.G.U.S..
Year Seven: Working with the SCPD/Ninth Circle
Following Oliver's incarceration, Team Arrow has been inactive for 7 months, however, after Diaz was captured and sent to Slabside Maximum Security Prison, in exchange for Oliver's freedom; the team has become active again. After Oliver’s release, he resumed his duties as the Green Arrow and became deputized by the Star City Police Department. After the Chimera Incident, the rest of the team were also deputized. They were later made into their own "vigilante task force" while still maintaining their authority.
In an erased future witnessed by Rip Hunter's team, by 2046 Star City was a battleground for various gangs, with Slade Wilson's son Grant Wilson having attacked the city to avenge his father's death. Grant's assault fifteen years prior to 2046 resulted in the death of John Diggle and Oliver Queen losing his right arm when Grant cut it off, Oliver going into self-imposed exile in the team's headquarters as he felt ashamed at his failure to protect his city. During this time, Diggle's son took on the Green Arrow mantle to try and protect the people of Star City, although he also changed his own name to Connor Hawke as he felt that he didn't deserve his original name of John Diggle Jr. after his failure to save his father. When the Waverider crashed into this timeline, the team were able to work with Hawke and Oliver- Oliver using an artificial arm he had acquired at some point- to rally a new offensive against Grant's men, the time-travelers leaving the city with hope that Oliver and Hawke would be able to make a difference in this city once again.
