Adrian Chase (Earth 87)

Simon Morrison (born April 21 2359), known under the alias Adrian Chase, is a male Human who lives in the 24th century who is the former district attorney of Star City and a former close collaborator/friend of Oliver Queen as mayor, helping him in cleaning up the streets through the legal system. He was the serial killer who was calling himself Prometheus, and not only knew that Oliver Queen is Green Arrow, but had a personal vendetta against him as well. Having lost his father 11 years ago at the hands of the Hood, Adrian desired retribution, and spent his time afterwards studying the Hood's skills and history, while also uncovering Oliver's true identity as the Green Arrow. In his alter-ego, Prometheus crusaded against the Green Arrow in order to destroy the vigilante's life and legacy. He had also been labeled by the media as the "Throwing Star Killer" for murdering people whose names formed anagrams of individuals on the List using shurikens made from Oliver's discarded arrows as a form of sending a twisted message to him.

Eventually, Adrian was defeated by Oliver and temporarily taken into custody by A.R.G.U.S.. After a short time spent in a glass-walled prison, he managed to escape to Lian Yu. After facing off with Oliver in battle once again, Adrian was able to escape from Lian Yu and escape from Team Arrow, Adrian continued to be a problem for the team 6 months after the battle on Lian Yu as he continued to fight Team Arrow.

Laurel Lance/Black Siren offers Adrian a place on her team of criminals and Adrian accepts Black Siren's offer.
