Quirk: Lumify

Details: The user's blood contains a sort of luminol solution chemical, and if the user consumes any form of hydrogen peroxide, it causes their blood to glow and make it look like they're emanating light. The hydrogen peroxide doesn't hurt them like it would hurt anyone else because the stomach has adapted enough that it can take large amounts of it. If the user consumes too much hydrogen peroxide, however, side effects may include high blood pressure, upset stomach, and/or dry throat and mouth.

(eh i hope i got that science right) (i had to watch a couple videos because you know there's gotta be an explanation for why the user look like they be glowin)
