Name: Hunter is the name he goes by, he doesn't use his old name.
Age: 37
Looks: Almost like young Clint Eastwood.
Backstory: Abused, alone and broken. Hunter has had a tough life but it works out in the end.
Hunter was born a bastard. He never knew his father. He was raised by his mother whose name was Ricky. She wasn't very educated and was barely scrapping by. She lived in an old rotting home with hunter and got money through anyway possible, even whoring. As such she was very abusive to hunter. Her punishments were very harsh towards Hunter. She would hit him, lock him in her basement, deprive him of food and even leave him outside the house sometimes for entire nights. When he was 9 he ran away and headed straight to the city slums. The city slums was a dangerous place, lots of people there commit the most horrific of crimes, murder, rape and even cannibalism. There he learnt to survive through any means necessary. He fashioned his own clothing, weapons and tools with the scraps he found in trash. He would find food and water in the trash or sewers. Luckily Hunter was pretty gifted and he tought himself lots of things like reading, maths, science. etc. He used to steal a lot of books from an old local library and continued to learn even more. Although Hunter has had a tough life, he still had a sense of humanity. Whenever he saw an innocent man in the slums being harassed he usually tried to help, but whenever he did, it usually ended in a massacre with Hunter butchering a whole squad of men just to protect this one person and the person he usually tries to help is more terrified than he was before Hunter stepped in. This earned him a title he didn't want and he was known among a lot of people in the slums as "The Butcher". When he turned 18 he decided to leave the slums because he thought he was confident enough, he could survive in the more wealthier areas. He was right, he got a job as a pretty successful mechanic and later started a business as an firearms dealer. When he turned 23 though he wanted to do something else. Something that would affect a larger amount of people. So he joined the army. Hunter actually made a very good soldier, spending time in the slums has helped with survival in harsh conditions, he was physically fit, his naturally gifted mind allows him to strategies and think through difficult situations, he is a very good marksman and has vast knowledge on weapons since he used be an arms dealer. He quickly ascended through the ranks of the army and became well known for his legendary operation "Subterfuge". Where Hunter and his squad have to infiltrate an enemy base and collect intel, they were caught once they collected the intel they needed though. They were forced to escape but they were pursued by an entire platoon of elite soldiers. Hunter stayed back though to slow them down and ensure the safety of his squad members by crippling and nearly killing the entire platoon of soldiers on his own. He returned and was given the military's most prestigious awards, the medal of honor.
TL;DR Zero to hero real quick
