Boody Rogers' Sparky Watts

"... Sparky started out as a college student, working his way through school by selling magazine subscriptions. A mad scientist named Doc Static offered to buy some of his magazines, in return for Sparky's assistance in an experiment. Doc then bombarded Sparky with cosmic rays, making him the strongest man in the world. Sparky also got super speed and super-tough skin (to the point where he had to shave with a blowtorch) in the bargain. He then proceeded to battle Nazis, super villains, monsters and the like, assisted by his sidekick, Slap Happy, with Doc in the background supplyng scientific expertise as needed. ..." (Quote from Don Markstein's Toonopedia: Sparky Watts)
