Robert Bruce Banner also known as the Incredible Hulk was born in Dayton, Ohio, to Dr. Brian and Rebecca Banner. As a child, Bruce was abused by his alcoholic father, who killed his wife when she and Bruce tried to escape from one of his drunken rages. A genius in nuclear physics, Robert Bruce Banner went to work for the United States Defense Department nuclear research facility at Desert Base, New Mexico.  On his mothers’ death anniversary, Bruce accidentally killed his father by causing him to fall and crack his skull on Rebecca's tombstone. Bruce repressed the memory of his actions and the police dismissed the death as a random mugging. Meanwhile back at work they were testing a Gamma Bomb and before Banner could get himself to safety, the gamma-bomb detonated, and intense waves of radiation hit the surface. Banner was irradiated with highly-charged radioactive particles, which caused Banner to change into The Incredible hulk.
