Idea #7 (My Hero Academia & Marvel/DC)

This is a My Hero Academia story mixed with Marvel or DC.

The concept is someone from either Marvel or DC is accidentally transported to the world of My Hero Academia where they are finally accepted because they have a major physical mutation (Marvel)/Inhuman with a major change in structure of the body (Marvel)/a completely physically changed Metahuman (DC)/or were in a major accident to become changed (DC) (Ex; Swamp thing, King Croc, etc.).

They use the opportunity to either become a hero through the academy and be accepted by the masses, a villain to find any possible way to get home or to become the pinnacle of this new world, or a civilian where they can finally be themselves, but where they are also pulled into superhero shenanigans because of outside forces (namely the author, this one would be more comedic).
