J. Donald Proctor is the heir apparent and public face of Proctor Products-- the chief business rival of Cradle Industries in Jolt City. The son of the company's founder, he eagerly awaits the day he can step into his father's shoes. J. Donald is a very close ally of mayoral candidate Carlos Canton; together they have big plans for the city, and neither is above playing dirty to achieve their aims.

For example, J. Donald hired the Little League of Doom to destroy a Cradle Industries refinery site under construction. Then, to cover his tracks after the de-powered team was arrested following their murderous rampage, his lawyers convinced the seven guilty boys to lie, pinning it on the eighth boy who had tried but failed to stop them.
