Killboy

Early life
David John Johnson was born in Queens, New York, to retired stuntman named Geraint and a housewife named Ashley. The family moved to Ultrar City when David was only 8. Shortly after his 11th birthday, David followed his parents to the local bank. However during the trip, the bank was raided by a group of criminals looking to make a robbery. Being held hostage, David's mother, Ashley, resisted to cooperate with the thugs, and was killed in front of the distraught David Johnson. After the robbery, David silently vowed to avenge his mother's death.

Growing up, David Johnson spent most of his life studying various martial arts. When he was 15, David was expelled from high school after attacking another student during baseball practice. Since then, David stayed living in a small apartment with his father, continuing to train and awaiting an opportunity to exact his revenge.

After his 20th birthday, David Johnson decided that he was prepared to face the criminal underworld of the city in hopes of not only releasing the city from crime's stranglehold, but finding the criminals responsible for the murder of his mother. So secretly equipping himself with his father's old stuntman gear, along with a modified balaclava and a redesigned steel bat, David went to the streets late at night, rendering several criminals unconscious. After several nights fighting criminals, David caught the attention of the media after infiltrating a crackhouse, dubbing the masked vigilante as Killboy, a menace that takes the law into his own hands.
