Diaperman! Okay...not so much a FAVORITE, but an obscure superhero none-the-less.
Diaperman, along with his best friend and trusted companion Sleepers, strive to make the City of Megopolis free of the controlling influences of such villains as the Spanker, a rubber-clad neer-do-well with a penchant for paddling; the Black Whip, a demented dominatrix who craves subservience from her minions at the tip of her whip! Other fetishistic characters make up the setting of the city of Megoplis, leaving it up to Diaperman, the Padded Paladin, to fight for justice in his own unique and soggy way.
