Since your quirk developed, it’s been powerful. Stronger than you can control more often than not, it’s a frequent issue you’ve had to face. It doesn’t help that your dream is to be a superhero. Someone who saves people, who can help those in trouble. But saving people means you need to be able to control your power so you don’t kill them. And that’s not something you can do.
When something as small as fear can set off your quirk, you need to be careful. You don’t go out much so you don’t hurt anyone. When you do have to go out, you go during the darkest hours, so there are no cars, and not a lot of people running around. This has worked for you for a while; your parents have never really been in the picture, so you do what you have to do. You had your monthly grocery run the night that everything went wrong.
“Give me all your money!” You freeze, as you feel something sharp pressing into your neck. “Fork it over and you won’t die.” Villain.
“Don’t do that- please,” you whisper, not wanting to kill him by mistake. The metal at your neck presses harder, and something clicks in your chest. In a burst, your quirk releases, setting off at max power. Time loses all meaning as you try to get your quirk back under control.
You’re not sure how long you’re fighting. Your quirk isn’t under your control, and you can hardly hear anymore. From what you can tell, there are heroes, but your quirk is keeping them away. They think you’re a villain. You close your eyes, your quirk fully overtaking you. Right as you’re slipping into total blackout, you fall to the ground, quirk gone.
“Hold on. This isn’t a villain- they just can’t control their quirk,” a deepish voice says, and you hear footsteps approaching. A hand takes your chin, forcing you to look up. The man- no, the hero standing there, is Eraser Head.
