"The Green Arrow is mine."

- Prometheus to Tobias Church

"Prometheus" is a mysterious hooded figure in Star City, bearing a dark suit similar to that of the Green Arrow. Prometheus is evidently aware of Oliver Queen's secret identities as The Hood/The Arrow as well as The Green Arrow, evidenced by the fact he targetted victims whose names formed anagrams for people on The List.

Biography
Little is known of this individual's past, even his real name. At some point for reasons unclear this individual became embittered towards Green Arrow and began acting as "Prometheus", wearing a dark suit almost identical to his, but with a full face mask and additional weapons.

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 SCIS 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, killing Conahan.

A few nights later, Prometheus somehow learned of Green Arrow's encounter with 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 ax 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 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, then left the scene of his slaughter.

Days later, Prometheus met Artemis alone on a rooftop, seemingly in league with her.

Personality
Little is known of this individual though he appears to have an obsession on Green Arrow for reasons unclear. His fixation runs deep enough that only he wants to kill Green Arrow so much that if anyone else tries, he'll kill them as he threatened Tobias Church with death if he killed Green Arrow, and later kept his promise when Tobias refused to stop pursuing the Green Arrow. He is also ruthless as he mercilessly attacked an officer multiple times and slaughtered him in cold blood.
