Super Cat

Super cat has many powers. Some of those powers are not actually powers yet it's easy for a cat with a puffed-up chest to think the world of himself.

If he never reveals his identity as Super cat, then, he's probably made some dreadful mistake in a universe where that's possible. Having said that, one of his superpowers is that he doesn't have to speak, and all will be known; he doesn't have to announce himself as Super cat. It's already known that he's super, super cat.
