When you were born... your mother died. Your father all for one didn't want you.. he saw you as a weakness. A weak spot. Deep down he knew he loved you. But as a feared villain he couldn't have any weak points... so he got rid of you... He didn't want it... and he thought you were dead. You were only 4 months old when this happened..
You traveled around a lot... until you were 7... you had to earn money somehow... you had to learn to grow up very early... You have learned to fight.. So you started fighting illegally on the streets. You have had many defeats... But over time, many victories too... You were now 12.. Even when you were young, you were very well known in the shadows.. a ruthless fighter..
But you didn't know that a pro hero was undercover. He had to watch the dark areas... and what was going on. It was Eraserhead. He was at that time 24.. He was dressed civilian.
You stood in front of your opponent... you were just waiting for the referee to give the signal
