Prometheus

"The Green Arrow is mine."

- Prometheus to Tobias Church.

"Prometheus" is the alias of an unnamed individual operating as a mysterious hooded figure in Star City, bearing a dark uniform similar to that of the Green Arrow.

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 uniform almost identical to his, but with a full face mask and additional weapons.

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 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 after Green Arrow defeated him and was being transfered 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.

Personality
Little is known of this individual though he appears to have a grudge against Green Arrow for reasons unclear. His grudge 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. He is also ruthless as he mercilessly attacked an officer multiple times and slaughtered him in cold blood.
