Dr. Curtis Connors lost his right arm while serving as an Army surgeon. Also a brilliant herpetologist, Connors became convinced he could apply his studies of certain reptiles' regenerative abilities to human physiology to help him to regain his limb.Isolating the reptile enzyme responsible for regeneration, he injected himself with an experimental formula of his own creation. The serum restored Connors' missing arm, but also triggered a horrific, body-wide mutation that transformed the hapless scientist into a savage, humanoid reptile calling itself the Lizard.
