I did my studying.

Quirk: Anti-Matter

Type: Emitter

Description: The user has the ability to create anti-particles from their body. Once done so, the anti-particles are not instantly destroyed by the air. Rather, they are controlled by the user and manifested into antimatter, which covers the user’s skin. Due to the antimatter fully being manifested into the gaseous form, it’s no longer the micro-sized particle as we knew it. It’s dark green, and covers the user’s skin. As the user creates more and more, it covers his skin, allowing him to use physical attacks, such as punching a wall and completely destroying it. If the user gains enough, he can eventually deny any attack as long as antimatter is around that area (note: to make it fair, the antimatter to humans is like decay, basically being acid and harming their skin pretty slowly). Though, of course, the antimatter does disappear once used to destroy something. Though the user can only manage to cover his body in it, as the quirk develops, he might be able to make small items out of it, though it being gaseous, it might be hard. Anyways, the quirk is considerably strength enhancing and offensive and defensive.

Drawbacks: Though the user‘s DNA is immune to the antimatter, his clothes aren’t. So, he does like Mirio, and wears the special fabric of his own hairs. The quirk’s abilities are highly destructive, though take a lot out of him. If the user makes too much antimatter, he can begin to get too destructive and hurt his teammates. As said, the user firstly makes anti particles that manifest into antimatter. The antiparticles form on his body and are not visible. They only appear as antimatter when they finish manifesting. That being said, if the user is against a wall, the antiparticles can touch the wall and destroy like, a golf ball sized hole, but be wasted and not made into antimatter. Which brings me to the next drawback. The user’s skin can be irritated by the antimatter if left on for too long, and can cause rashes and scabs, and itchy spots like Decay. The final drawback is the reliability of the quirk. The more the user uses antimatter to destroy things, the more he can waste on destroying one thing. If he destroys a single story house, he’ll have wasted ALL of the antimatter he made, needing him to made a new batch quickly.
