Mewtwo - Pure psychic devastation would flatten most low-level foes. Dialga - Doubt even raid bosses could withstand Roar of Time Nurse Joy - Just in case my first two faint. And she's kind of hot, too. Pyramid Head from Silent Hill 2 - Completely indestructible. Only time he dies is when he does hara-kiri. And he's in the "Downpour" Surprise ending, which is sort of cartoony, so he's technically a cartoon character. He'd be the ultimate sword-bearer. Batman - The old school, neurotic, split personality vigilante, Robin-free Batman. Because Batman is awesome.
