Well, The Bulge is his superhero name, his "real" name is Porno Mann. He was an adult film actor in the sixties. He was born with his powers but for most of his life he kept them secret until the eighties at which point he was inspired to join a team of heroes trying to save their city (which was a fictionalised San Francisco). For few years he used his hero fame to enhance his civilian career but he official retired in the early ninties. In the game, he would have been pulled out of quiet retirement by the other heroes to help them save the world again.
The idea was to make a joke hero (all the characters where jokes) that was still effective. The Bulge's player took every power that could be easily be sex jokes. He had elongation, fiction control, anatomical seperation, and a bunch of others, which looked hiliariously funny on a character sheet with "The Bulge" as the title. But he could used them as effective powers when the game really got going.
He was the oldest of the heroes by a long shot. He had immunity aging so he was still young, even though he was in his sixties. He was also the only member of the party who had dealt with their enemy before and he served as the mentor of the group. He liked to dispence wisdom using prono analogies which, though odd, usually fit the situation and actually succeeded in passing along the lesson. We designed the character to be a walking dick joke but we got so interested in him that we gave him alot of personality and background. We still talk about him, even though we never actually got to play the game he was designed for.
