"I've studied you, Oliver Queen. I know everything, who you love, who you trust, who you've hurt. But do you know how easy it was to turn Evelyn against you? How easy it will be to turn them all? You're not a hero. You're a killer. And I'm going to show you that. I'm going to show you how everything you touch dies."

- Prometheus to Green Arrow

"Prometheus" (born c. 2359) is a mysterious hooded figure in Star City with a personal vendetta against Oliver Queen. Having lost someone to The Hood, he trained for 11 years in order to gain retribution, studying the vigilante's skillset and history, while also uncovering his true identity. In his alter-ego, he crusades against the Green Arrow in order to destroy the hero's life and legacy. Prometheus has also been labeled by the media as the "Throwing Star Killer" for murdering people, whose names formed anagrams of people on The List, with shurikens.

Early life
In around 2359, Justin Claybourne had an illegitimate child with his mistress, Amanda Westfield, said to be the man who would grow up to use the "Prometheus" mantle. In 2378, The Hood killed his father, Justin Claybourne, causing him to leave his mother after Claybourne's funeral, and then seek vengeance upon the vigilante.

Since 2378 Prometheus has been training for 11 years to learn everything he could about his enemies, and knows several specific moves that were taught to Oliver by Talia al Ghul during his time in Russia, implying Talia may have trained Prometheus also. He is also armed with an array of weapons forged from Oliver's discarded arrows which only Star City Police Department would have access to, implicating Prometheus to be a SCIS officer. He also uses a suit strikingly similar to Oliver's suit from his days as the Hood, but darker and with a full face mask and adopted the name "Prometheus".

Prometheus also somehow discovered that Green Arrow, the apparent successor to The Hood/The Arrow, is in fact the same individual, and thus Roy Harper's deception, and also became aware of the existence of The List. This also indicates that Prometheus became aware of Green Arrow's identity as Oliver Queen, prior to beginning his crusade. He also somehow became aware of time travel and the multiverse, as well as Team Flash's pipeline prison and the Waverider, indicating he's kept tabs on Barry Allen/The Flash and somehow has kept tabs on the Legends. Whether Prometheus was aware of this prior to his crusade or learned this from Evelyn Sharp isn't yet clear.

Beginning his crusade
5 months following Damien Darhk's death Prometheus began his crusade by targeting individuals in Star City whose names formed anagrams to other names on The List. His first victim was Lieutenant Conahan.

Conflict with Tobias Church
When Lieutenant Conahan was leaving the SCIS precinct, he noticed Prometheus on the rooftop. Mistaking him for Green Arrow, Conahan asked if he could help him, but was shot by an arrow. Conahan painfully tried to shoot back, but Prometheus dodged his shots, leaped to the ground and threw a shuriken to disarm him. As Conahan tried to flee, Prometheus threw a knife into his leg, knocking the officer down. As Conahan desperately tried to crawl away, Prometheus slowly walked up to him, sword in hand, and, when asked if he was Green Arrow, coldly replied that he wasn't, and killed Conahan.

A few nights later, Prometheus somehow learned of Green Arrow's encounter with the crime lord Tobias Church amidst his illegal deal with AmerTek Industries, where he almost killed Green Arrow. In response, Prometheus stalked Church and as he left Club XLR8, he killed his two bodyguards. While Church mistook him for Green Arrow, Prometheus threw an axe into Church's shoulder, leaped to the ground and slammed Church to the pavement. Prometheus warned Church that Green Arrow was his to kill, and if he killed Green Arrow, then he'd die too.

After a couple of weeks, Prometheus learned that Church had ignored his warnings and confronted him at the docks, reminding him of his threat and tried to kill him, but Church had his own bodyguard to protect him. Prometheus reminded Church he had his second warning and wouldn't be given a third and left. After Church was arrested following his defeat by Green Arrow, being transferred to Iron Heights, Prometheus attacked the convoy of SCIS shuttles escorting him. After slaughtering the escorting officers, he confronted Church in the shuttle. Church tried to plead for his life by telling him Green Arrow's identity: Oliver Queen. When Church asked if they were cool, Prometheus threw a shuriken into his neck and killed him, and replied that they were, then left the scene of his slaughter.

Crusading against Green Arrow
With Green Arrow aware of his existence, Prometheus lured him, Red Arrow and Spartan to a construction site, using Church's communicator to lure them out. After they tracked the communicator he called it on his own communicator, heavily breathing into the communicator, as Green Arrow answered. He then ignited a message on the ground, "SO IT BEGINS". From there, he continued killing civilians to form more anagrams of individuals on the List including Peter Meld and Gay Eked. Their names, and Conahan and Church's all spelled out the names Adam Hunt, Ted Gaynor, Palmer Cokes and Sachi Beech.

Finding more six more potential victims after discovering Prometheus' pattern, Team Arrow sent a member to each one. Prometheus went after a train driver but was confronted by Evelyn Sharp/Artemis. They entered into a duel where Artemis managed to cut Prometheus right arm, before Green Arrow came to Artemis' rescue, shooting an arrow into his back. Instantly recognizing it as an explosive arrow Prometheus threw it onto the roof where it exploded and Prometheus escaped through the hole made, but left a bomb which blew up the train though Green Arrow and Artemis escaped with the train driver. Later Prometheus sneaked into Quentin Lance's apartment and left a cut on his arm just like the cut Artemis gave Prometheus, and left a shuriken to implicate him.

Some time after Prometheus' encounter with Evelyn, he sought her out and manipulated her into betraying Oliver, as she had become resentful of him after learning he was the Hood, promising to let her watch when he finally kills Green Arrow. As a result of Evelyn's betrayal Prometheus was able to learn the identities of every Team Arrow member, as well as information on their personal lives. Days later, Prometheus met Artemis alone on a rooftop, where she assured him she wasn't followed and told him Team Arrow doesn't suspect her true allegiance.

At some point in December 2389, Prometheus went to Central City, where he broke into S.T.A.R. Labs without setting off any alarms and freed Laurel Lance/Black Siren, the Earth Two doppelgänger of Laurel Lance/Black Canary, to impersonate her Earth One counterpart, threatening to kill her if she didn't comply. Reluctantly, Black Siren agreed and, to maintain her cover, Prometheus told her vital information on Earth One Laurel's life. He also informed her of the Waverider and the Legends, so Black Siren could use the cover story that Sara brought her back and transported her to the present. Team Flash would be unaware of the breakout for almost 3 days.

During Christmas, Prometheus, while sharpening his weapons, was approached by Evelyn with photographs and addresses of Felicity Smoak and Rory Regan. Evelyn then asked Prometheus to be there when he kills Oliver, Prometheus stated that he doesn't intend to kill Oliver, but to make him wish he was dead. Prometheus later attacked Curtis Holt and his husband, Paul, effortlessly defeating him and injecting him with the drug, Dycloseral, leaving Oliver and Team Arrow that he is aware of their secret identities and that he is Justin Claybourne. At Claybourne Pharmaceuticals, Prometheus confronted Green Arrow and engaged him in a battle. Though Green Arrow initially had the upper hand, Prometheus ultimately bests him - only for Wild Dog to shot his katana out of his hand, causing Artemis to intervene and reveal her true allegiance. As Green Arrow and Wild Dog stood in shock Artemis fired a smoke arrow to cover her and Prometheus' escape.

While investigating Claybourne Pharmaceuticals, Detective Billy Malone discovered a photograph of a baby and sends it to Felicity, before Prometheus appended him. Tracking Prometheus to the location of where Oliver killed Claybourne, Green Arrow discovered that Prometheus had recreated the whole scene in which of all the people that he'd killed when pursuing Claybourne before confronting Prometheus in the exact spot in which he killed Claybourne. Prometheus asked if Green Arrow even hesitated when he killed him, or he was merely another name on the List. They engaged in a fight before landing crashing into one of the building's floors, in which Prometheus told Green Arrow that he knows everything about him and is going to show him and everyone else that everything Oliver touches dies. Having dressed Billy Malone in his suit beforehand, Prometheus ultimately orchestrated Green Arrow killing him in order to prove his point, telling him over a wireless speaker attached to Billy that everyone loves dies. Somehow Prometheus also imitated Lyla Michaels' voice to trick Diggle into returning to the safe-house his family were staying in, and tipped off the SCIS which allowed them to recapture him. After this Prometheus sent Earth Two Laurel to impersonate her Earth One counterpart, roughly 3 days after breaking her out of S.T.A.R. Labs.

Eventually Black Siren's cover was blown and Prometheus furiously choked her, reminding her that her freedom is only conditional while she follows his instructions. Felicity would later allow Black Siren to escape, hoping she would lead Team Arrow to Prometheus, which proved successful. Prometheus knocked out Ragman before confronting Green Arrow, which lead to another fight between the two. Shrugging off a drugged-dart shot at him by Green Arrow, he told the archer he had a tolerance to most drugs and Prometheus bests him once more. He then taunts him over saving Felicity or going after him, concluding the ordeal by kicking Green Arrow through a wooden wall, to where Black Siren and Felicity are, before escaping.

Personality
Little is known about Prometheus other than his extreme hatred for Oliver Queen to the point of obsession for ambiguous reasons. Prometheus's fixation on Oliver runs so deep that he will threaten and even kill those who threaten Oliver's life, as he wishes to destroy Oliver himself, as seen with Tobias Church when he made an attempt on Oliver's life. Prometheus's methods against Oliver are ruthless, merciless, and psychologically personal as he willing kills innocent people simply because their names are anagrams on Oliver's List, using his victims to recreate the scene in which Oliver killed Justin Claybourne, setting Oliver up to kill Billy Malone who was his ex-fiancée's current boyfriend, and freeing Black Siren because she is the Doppelgänger of Laurel Lance whom Oliver loved. Prometheus's end goal is unclear, however he has stated to Evelyn Sharp that he wants to make Oliver wish he was dead, and prove to him that everything that he touches dies.

Behind the scenes

 * In DC comics, Prometheus is an alias used by multiple villains. However, showrunner Marc Guggenheim has stated that the show's version of the character is not based on any comic character. Nevertheless, this version does resemble the one depicted by Grant Morrison in looks and modus operandi, being a "dark mirror version" of the hero he opposes.
