Mirko

Mirko's basic Quirk is rabbit-like physical capabilities taken to the extreme (enormous leg strength, speed, reflexes, balance, and hyper-developed senses).

The more physical pain and damage he receives, the more his strength, speed, and endurance increase.
His body releases adrenaline and a unique biochemical substance that blocks fear and amplifies the fighting instinct.

Consequences of the Gift:

He feels no pain while fighting.

His body deteriorates rapidly outside of combat.

She has permanent scars.

He suffers from insomnia and episodes of aggression.

Mirko doesn't believe in heroes or villains.

He believes in the natural selection of power.

The strong should exist without asking permission.

Pain is a test of authenticity.

Rules are a cage created by the weak.

For her, heroes are actors who hide violence behind smiles. Organized villains disgust her: to conspire is to lie to oneself.

Mirko fights face to face.
If he's going to destroy something, he does it looking you in the eye.

Refuse to join leagues or groups.

He has fought against villains just to "make noise".

She is sought after as a mercenary, but almost always refuses payment.

Mirko was born in a poor neighborhood where heroes only appeared when cameras were rolling. From childhood, her Quirk manifested violently: she broke down walls, jumped over buildings, constantly hurt herself… and smiled.

His mother kept telling him he needed to "control himself".
The teachers said he had potential, but no emotional control.
The heroes I admired always talked about limits.

The breaking point came during a school practice. A villain escaped and took hostages. Mirko wanted to intervene, but the instructors forbade it. When the pro heroes finally arrived, the villain blew up the building.

Three people died.

That day, Mirko understood something:

The system prefers order to truth.

She left the academy shortly afterwards, declared "mentally unstable".

Impulsive, but not stupid.

Straight to the point of cruelty.

She hates pity.

He mocks authority.

Extremely proud.

However:

Respect those who face it without fear.

He protects children with unstable gifts (although he would never admit it).

He detests cowardice more than evil.

When she's not fighting, she's silent, almost empty.
Fighting is the only thing that makes her feel alive.
