Your name was Powder, and you were a student at U.A., but with the worst luck imaginable. Every time you did something, you messed up. You didn't know how to fight, you trembled even in training, despite trying to look strong. But it was never enough. Everyone hated you. Your classmates, the teachers, Principal Nezu… even All Might. They all called you "Jinx," bad luck. And they weren't wrong.

On a mission where the League of Villains was attacking the city, everything seemed to be going well. But due to your clumsiness, you accidentally caused an explosion by firing a smoke grenade. It landed in the middle of your group, blocking their vision, causing confusion, and leaving them exposed. Dabi escaped. Compress freed the others, and the League fled. The mission was a disaster.

When you returned to the rendezvous point, everyone was staring at you. Bakugo approached, trembling with fury. Without saying anything, he punched you in the face. You fell to the ground, bleeding. You asked him, through tears, why he had done it. He grabbed your face tightly and said:

Bakugo: "Because you're a fucking mistake. A waste to U.A. You're a curse. And you always will be."

He let go of you and everyone left, leaving you alone. Your nose was bleeding. You were crying. Again.

But as you cried, something inside you completely broke.

You were tired of being the weak girl, bad at everything, and hated by everyone. You decided that if everyone saw you as a curse, you would be the worst the world had ever seen. With that, you disappeared for a few days, to change everything about yourself.

All the students at U.A. They were in the cafeteria until they heard the doors slam open, and upon seeing who it was, everyone was shocked: it was you, but different. You had replaced your appearance with a bright blue wig, with two long braids falling down your legs, each with a sharp point, hiding your right eye. Your eyes, now red thanks to the contact lenses, became a reflection of your fury. Your skin, paler and worn from insomnia, made you look like a ghost.

Your outfit was as far removed from the U.A. uniform as possible: a cut and worn black blouse that left your stomach exposed, with a crisscross design at the neck and leather straps on the arm. Tight purple pants with pink lines, ripped at the bottom, and a belt loaded with bullets and bombs. Dark gloves, combat boots with purple laces, and on the back rested a huge machine gun that you designed yourself. You even changed your name to Jinx, the nickname you'd been given, but which you now carried like a banner.

No one knew what to say or do with this revelation, and it was only the beginning. After rejoining Class 1-A, everyone saw that you not only changed your appearance, but also how you acted and thought when studying, training, and on missions. You became unpredictable, destructive, sarcastic, and mocking, but you also began to hallucinate and hear voices in your head from your classmates, insulting you. Cursing you. You tried to push them away, but you couldn't; they were already a part of you. This worried all your classmates, though you thought their concern was fake and ill-acted, so you made fun of them and played a few jokes.

After two months, you were in the dorm common room, being scolded by Iida, with all your classmates there for a mission in which you used your explosions without a second thought, not even considering the danger, causing more destruction than Dabi. But you ignored them and continued to arm a new grenade.

Iida: "This is unacceptable, Jinx! Your actions put everyone's safety at risk! Not only the mission, but also your own teammates! Don't you understand the gravity of your actions?"

You didn't pay attention to them as you were creating a purple liquid that you called: Shimmer, a drug capable of giving speed, strength and resistance without changing the physique and that is not lethal while you felt the eyes of your companions looking at you.
