Peter Bishop grew up as the neglected son of a mad scientist.

After his dad's mental institutionalization, Peter aimed to make himself as different from his father as he could. He's a college drop-out that passed for several months as a chemistry professor, along with an intuitive mathematician with a gambling problem.

Peter is now a civilian consultant for the FBI.
