Jack Heracles was saved by All Might when he was eight years old. All Might tried to save as many people as he could, still over hundreds of people perished. Of those who lost their lives were Jack's parents. He can't remember them though, what he does remember is the face All Might was wearing when he found him. That smile that seemed like it could brighten anyone's day, like Jack's existence meant so much to him even though they didn't know each other. Jack knew one thing after all of this, he wanted to be A Hero of Justice! A couple of weeks went by and Jack was still in the hospital healing from the tragedy he just endured. The doctor came up to him and said he has a visitor which made the young man curious, he doesn't know anybody. In came All Might asking Jack had anywhere to stay (already knowing the answer). He said no then was asked if he wanted All Might to adopt him knowing that no one can find out about this. Jack accepted this immediately.
Five years went by and Jack could finally attend UA, the school his adopted father went. Jack was practically brimming with excitement. Over the five years after the fire Jack had grown a lot like All Might, turning himself into the perfect weapon for others to use. He looked like he was sculpted into a Greek God (hense the name Heracles). He also trained himself in hand to hand combat because he doesn't want to use his quirk "Time Alter" which can essentially stop time at will, unless absolutely necessary, the backlash is certainly not to be trifled with. He named the martial art he specializes in Super Bajiquan because of the power he can put into his punches and kicks are super human. Jack now stood 6'4" wearing a black muscle shirt, shooting sleeve on his right arm, and tight sweatpants that showed of his bulging physique.
As Jack walks to the front doors of UA he can't help but observe a helpless green haired kid almost fall probably due to his nervousness but is saved by a female using her anti-gravity quirk. I walk over there to see if he was okay and he gives me a forced smile and a thumbs up. Not wanting to poke my nose into someone else's business I decided to leave him alone and head to the auditorium where we will find out about the entrance exam. I will save everyone, this is my only path, otherwise, all those people who died in the fire would have died for nothing. This is the burden that I carry alone. I am the alturistic hero.
