In the series, Stockman explained that he always had an evil streak in his heart as a child prodigy being pushed around by his classmates, so he decided to make himself an amazing intellect by presenting a volcano with real lava at the school science fair. To his dismay, however, that resulted with the entire gym burning down and him getting expelled. As an adult, he tried re-developing his intellect by getting a job as an inventor at TCRI, but was fired for an incident involving spilled copier toner, so he vowed revenge on his classmates and co-workers for making a mockery of him and his failing intellect.
