My Hero Academia: Quirk Ideas

Pulse🌀

Pulse(Emitter)
User emits a painful force through their palms via touch. The wave disrupts the quirk factor, stun people, and can control how much of the wave goes through your target. People that it gets used on are left numb, and can break solid objects,make liquids vibrate, and can react with the air.

Drawbacks-Body aches, dizziness, and sore hands. You also can't use it without touching targets

Special Moves
Nerve Rift-blasts target with a wave so powerful it makes their nerves jump

Ripple-emits a wave that isn't the most powerful, but can your enemies twitch

Crusher Concussion-emits a decimating wave that can topple buildings , cause earthquakes, and can rip human bodies apart

Details:
This kind of reminds me of cataclysm from miraculous lady bug

I got the idea from hitting my elbow on that one nerve that numbs your whole arm

Maybe you are a villain

Or possibly a vigilante hero because nobody really believed you could use your powers for good

Sometimes you accidentally pulse yourself
