He would fight with the pencils he uses to sketch characters and strips. He'll have the ability to amalgamate characters and powers into himself allowing him to transform into his own creations with awesome fusions (so, for example, one of his transformations would have him huge and green with control of tentacle type tendril things, the ability to charge and throw cards (or, in this case, concept art) and three gargantuan claws (chanelling the spirits of The Hulk, Venom, Gambit and Wolverine)).

He'd obviously be a secret character to unlock after completing the game on the hardest difficulty or something xP
