The Key is a super-villain and enemy to the Justice League. Using psychotropic drugs he unlocked the potential of his own brain-power, dramatically increasing his intelligence. His genius-level designs allowed him to become a super-criminal, with robot henchmen and a key-blaster as his weapon. He has been a member of the Injustice League, Intergang and the Secret Society of Super-Villains. The Key was created by Gardner Fox and Mike Sekowsky, first appearing in Justice League of America #41. (1965)
