Doctor Dungeon

From publisher blurb: ROLL AND DIE! A huge fan of tabletop roleplaying games and a master at engineering deathtrap-filled mazes, Doctor Dungeon is a favorite in the villain community. All manner of baddies vie to place their heroic nemeses in his mazes and watch their demise with glee! Super Powered Legends. Because sometimes you a need a character everyone recognizes, even when meeting them for the first time.
