World: my hero academia
Description: A boy with the quirk to turn literally anything(biological as well) into a demonic weapon of his choosing applies to UA, and after an amazing showing of his quirk he gets accepted. But unbeknownst to the rest of the school he holds a secret about his quirk that only a few know about. The fact that his quirk is a mutation type and one with as many benefits as there are side effects!
Quirk: The devil of war
Abilities: With a single touch the user is able to turn anything into a demonic weapon of the user's choosing instantly. This works on all things biological or not. The item retains the abilities of its previous state, whether that be a quirk, some mechanical function, or something else entirely. Also the user instantly masters the weapons in which he uses.
Side effects: The more the user uses his ability the more demonic in both appearance wise and biologically he becomes. While this does boost the main ability immensely along with giving the user access to several abilities such as super strength, speed, and ability, it also forces an aura which causes the people near them to lash out with the sin that best represents them. Though keep in mind the demonification process is a slow one, and only through tremendous stress or strain on his body does it speed up.
Quirk type: mutant
MC on the power scale of MHA: The MC is very powerful. Enough to utterly destroy Deku in the recent manga chapters with relative ease.
Suggestion: since the character is so powerful I'd suggest you make it so he's really reluctant to fight too hard or use his quirk to its fullest extent. Also I'd suggest forceing the MC in a situation were he has to turn Nomu into a weapon( preferably a scythe).
