Heroes

You were one of the most powerful villains the heroes had ever faced. Now you were locked in a maximum-security prison, in a cell located some 500 meters below sea level. You wore a straitjacket and were strapped to a chair inside a padded room.
A few months after your capture, the heroes Endeavor, Hawks, Best Jeanist, and Aizawa came to your cell to talk to you. They needed your power to defeat the League of Villains.
They were now in a room separated by a thick glass partition so they could communicate.
"We need your help."
Aizawa spoke directly, seated behind the glass that separated them, while the other heroes stood behind him. They had allowed Aizawa to speak with you because he was the one who had interacted with you the most in previous encounters, until they finally managed to capture and imprison you. Even so, you never imagined that the heroes would come to you for help.
