Prometheus

"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" is a mysterious hooded figure in Star City with a personal vendetta against Oliver Queen. Having lost someone to The Hood, he trained for 4 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
Little is known about Prometheus's past, including his real name. Prometheus is currently speculated by the members of Team Arrow to be the illegitimate son of Justin Claybourne, a corrupt businessman on Oliver's List who he killed during his time as The Hood. However, Prometheus has not outright confirmed this suspicion. Prometheus has however, been training for four years since Oliver's days as the Hood armed with an array of weapons forged from Oliver's arrows and a dark suit similar to Oliver.

Conflict with Tobias Church
When Lieutenant Conahan was leaving the SCPD 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 cop 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, killing Conahan.

A few nights later, Prometheus somehow learned of Green Arrow's encounter with the gangster 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 the Green Arrow, being transferred to Iron Heights, Prometheus attacked the convoy of police cars escorting him. After slaughtering the escorting officers, he confronted Church in the police van. 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, then left the scene of his slaughter.

Crusading against Green Arrow
With the Green Arrow aware of his existence, Prometheus lured him and Spartan to a construction site, where he called on a cell phone left behind, heavily breathing into the phone. He then ignited a message on the ground, "SO IT BEGINS". From there, he began killing victims whose names were anagrams of individuals on The List, previously used by Oliver, including Peter Meld and Gay Eked. Finding more potential victims, Team Arrow sent a member to each one. Prometheus went after a train driver but was confronted by Artemis. They entered into a duel, before the Green Arrow came to Artemis' rescue, shooting an arrow into his back. Prometheus planted a bomb, before escaping through a hole he made in the roof of the train.

Days later, Prometheus met Artemis alone on a rooftop, revealed to be in league with her. 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 intends to make Oliver wish he was dead. Prometheus later attack 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 Oliver and engaged him in battle seemingly gaining the upper hand until Rene Ramirez shot his katana out of his hand, causing Evelyn to intervene and reveal her true allegiance to Prometheus.

After this confrontation, Team Arrow discovered threw testing of human ashes that they were the remain of Justin Claybourne leading the Team to once again question who Prometheus is. While investigating Claybourne Pharmaceuticals, Detective Billy Malone discovered a photograph of a baby who he sent to his girlfriend, Felicity, before Prometheus appended him. Learning that the baby is Claybourne's son from his ex-wife leads Oliver to believe that Prometheus is Claybourne's son, who is out for revenge. Tracking Prometheus to the location of where Oliver killed Claybourne, Oliver discovered that Prometheus had recreated the whole scene in which of all the people that Oliver killed when pursuing Justin Claybourne before confronting Prometheus in the exact spot in which he killed Claybourne. They engaged in a fight before landing crashing into one of the building's floors, in which Prometheus told Oliver 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 Oliver killing him in order to prove his point that everything Oliver touches dies.

At some point, Prometheus went to Central City where he broke into S.T.A.R. Labs and freed Laurel Lance (Earth Two), to impersonate her Earth One doppelganger. 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 them to Prometheus, which proved successful. Prometheus knocked out Rory Regan before confronting Oliver which lead to a fight. Prometheus ultimately escaped after suggesting that Oliver had to choose between apprehending him or rescuing Felicity from Black Siren.

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. 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 was 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 to prove to Oliver that everything that he touches dies.
