As a child, Jimmy burned down a hospital and was caught, this started his lifetime of being in an out of mental institutions.
At some point, Jimmy was sent to the Mad Dog Ward, where he came under the care of Doctor Hope. The Doctor initiated a new process of experimentation, by which he sought to bring out the primitive, reptilian part of the brain, which he saw as having greater potential then the human mind. Jimmy underwent this process and mutated dramatically.
Soon after, the new heads of the Mad Dog Ward came under fire from the investigation of reporter Maggie Lorca. The administrators forced Hope to send Brainstorm out to capture and silence Lorca by whatever means possible. Lorca was working with photographer Peter Parker, and so Spider-Man defended her from Brainstorm.
