Mt. Lady

Cold and distant.
She no longer seeks anyone's approval.
He harbors a deep resentment towards society.
It protects those who were also rejected for having "terrifying" Quirks.

Just becoming giant, nothing new bro

To demonstrate that hero society judges people by the appearance of their Quirks rather than their actions. That's why it gathers people discriminated against for their gifts and forms a group of villains who consider themselves "the monsters society created."

Ever since she was a child, her gigantification Quirk caused problems. She couldn't control her size well, and every time she grew by accident, she would break houses, cars, or streets.
Although she never intentionally hurt anyone, the news always referred to her as "the disaster girl".
The parents would lead their children away when she passed by.
At school, nobody wanted to be near her because they thought she might crush them.
Over the years she decided to become a heroine to prove that she was not a monster.
But the public never forgot his past.
If another hero destroyed a building during a fight, it was called "collateral damage".
If she broke down even one wall, the headlines would say:
"Once again, the giant destroys the city."
Online campaigns appeared demanding that he be banned from using his Quirk in populated areas.
Even some victims of villain-caused disasters blamed her simply because "it was always the giantess who ended up destroying more things."
One day, during the rescue of hundreds of people, a building collapsed. She managed to save almost everyone, but a few people died.
The media ignored the hundreds of survivors.
They only showed images of his enormous feet among the rubble.
They called her a murderer.
The Heroes Commission suspended it to calm public opinion.
Meanwhile, other heroes who had caused similar damage continued working.
