Superduperman Vs. Megaton Man

 

Superhero parodies have been around almost as long as superheroes themselves, and this first one I ever remember reading was Superduperman in a Mad Magazine reprint.  I remember finding it hilarious and being impressed by the art - which was no wonder since it was illustrated by Wally Wood, a master of traditional comics.  I was glad when I discovered the existence of Not Brand Echh! a few years later, a series that parodied Marvel heroes in a similar manner.
