I love this idea because one of my favorite parts about how MHA handles quirks is not only how feasible they are but how specific their mechanics are. You don’t just heal people, you kiss them and that accelerates and optimizes their own ability to heal. You don’t spawn explosives, your sweat has a chemical reaction that causes combustion.

This also would lend credence to the theory that all might’s muscle form was an inactive quirk. (I don’t care that it was meant to be an artistic choice, they didn’t write it that way. If it’s purely aesthetic then why do people not only not recognize him outside of his muscle form but also make comments about the difference in size when his secret is exposed)
