Originally a chemist with Intergang, the man who would be known as the Key develops mind-expanding "psycho-chemicals" that activate his ten senses and help him plan crimes mere humans can never hope to understand. Armed with these plans, a series of henchmen known as the "Key-Men", and a "key blaster", the Key has several failed run-ins with the JLA.
The Key returns, after spending years in hibernation. The psycho-chemicals he has been ingesting have altered his appearance into a pale, cadaverous form, and heightened his mental abilities. He manages to infiltrate the JLA headquarters, and traps the team in a fantasy realm of their own creation, intending to siphon off the energies of their inevitable victory in order to increase his power. He almost succeeds if not for the intervention of Connor Hawke, who beams up to the JLA headquarters while the Key is present due to a pre-arranged meeting to discuss him becoming a member of the League. He eventually returns to fight the Batman, attempting to provoke the Dark Knight into murdering him so he could escape life itself, but the plan proves unsuccessful.
Now with telepathic powers thanks to a cybernetic implant, he tries to destroy the League. After a long battle with Batman, Green Arrow, Black Canary, and Manitou Dawn, he is beaten and sent to "the dream realm", a place for telepaths, where he can think in peace. He somehow escapes, as he is later seen fighting in the Battle of Metropolis.
He appears as leader of a group of villains seeking to avoid being sent to the prison planet. He was last seen being a prisoner on the JLA Watchtower in the holding cells; unable to escape.
