Super

Super is a god and the original of SuperSupermario24/Lnsmall.

His duty is to protect certain universes or sets of universes (i.e. "canon" ones that appear in fiction); he does not let anything into them, and does not let anything leave (when someone goes to another universe in some other whatever, it's just part of the "set" of universes it takes place in). (this is to explain why the crap that goes on in The Multiverse doesn't affect the actual franchises it's based off of)
