History
Aaron Helzinger was a giant of a man prone to fits of homicidal rage. Due to these violent episodes he was remanded to the care of Arkham Asylum. A surgeon at Arkham removed Helzinger's amygdala cluster in the hopes of curing the psychotic episodes. This procedure yielded unexpected results however as Amygdala became exceedingly angry in opposition to what the surgery was supposed to achieve.While residing at Arkham, Amygdala became a pawn of the hospital's latest director, Jeremiah Arkham. In the hopes of breaking the spirit of his most recent patient, Batman, Arkham prodded Amygdala into attacking him. Batman fought and quickly subdued Amygdala, but was then forced to face a larger throng of blood-crazed patients. read more
