Oni-sash, also known as Matthew Thompson, grew up on the streets of Chicago. As most children, he had a sense for adventure and the mysteries of the world he lived in, but had little chance to go out and explore. Most of the days, he was kept inside of his home with his mother, Lisa. During these times, Matthew's father, also named Matthew, left for strip clubs, drug deals, or gambling/drinking with his own siblings or co-workers.
Years passed and by the time Matthew was 11 years old, he started to desire to see the world he lived in. While his parents went to sleep, he left the building to go across the city streets. He had always been homeschooled by a number of programs and his mother, but never really left the house or made friends. As he set out into the city, he witnessed multiple things. Men driving through the streets, shooting at one another! Women in flimsy clothing whistling and being affectionate to strange men passing by. As he wandered through the city, going deeper and deeper, he came across and ally way. Here was where it all happened.
A black guy, probably early twenties, was throwing around a girl in the alley way. He kept yelling and yelling about money, trust, hoes, and clients, but Matthew had no idea what this was about. He kept smacking her around until Matthew had enough. Matthew searched for something to use and found a broken bottle nearby. He reached for and crept along the dark walls of the alley, waiting for a time to get the so-called "Pimp". The young man had the girl on the ground and was about to finally end it. He slowly pulled out a nine MM and pointed it right at the girl, confident at his righteous actions.
Matthew jumped from the shadows, stabbed the broken bottle into his right side, and jumped back to hide if he tried to look. The man grabbed his side in a screamless agony, dropping the gun next to him. Matthew saw the gun, leaped for the gun and slid to the wall again, now getting the young man's attention. The young man tried to reach for Matthew, but barely took a step before he was blown with three holes. The woman screamed from the shots and a sense of adrenaline and pride filled Matthew's chest. His first kill. He had to leave quickly, before he was going to get caught. Matthew glanced over to the girl, who is cowering at fear towards him, expecting him to kill her. It was a very pleasing sight. Matthew held the gun barrell towards the girl, and ended her story. Matthew ran back to his home, with the gun, and hide in his room once again. Waiting for the day till he can do this all over again.
Over the next nine years, Matthew developed a strong mastery of many guns, blades, and fighting styles through his expierences in the city. He had to pay off mentors here and there, pay for information and tools. He was now a strong force to not take lightly. Through years of development, he has heard of stories of other famous heroes and villians. Batman, Deathstroke, Joker, Nightwing, Green Arrow, Spider-man, Iron man, and Captain America. Their morales and beliefs never interested him. Heroes and Villians usually have some personal issue with society or someone they are fighting, but their own choices, tactics, weapons, fighting styles. Now that is what interested Matthew. Even though Matthew could easily be the CEO of any major corporation or development team, he always wanted to cause more fear and bloodshed into the lives of others and be given profit from it. At nineteen years of age, Matthew applied for the army and was sent off to fight on enemy territory in Korea. Through his expierences, he became a prisoner of war and was tortured ruthlessly for what seemed like decades, but he never showed weakness to his captors. After two years as a prisoner, he escaped and took out the entire base he was kept in. He radioed in a request for pick up and was shortly rescued and returned to the states.
After the war, he became more serious about spreading the violence he had come to love and welcome into his life. He took on the short-sword and pistol as his weapons from there on. He thought of a way to cover his identity and created a costume of his own. A kevlar torso, pants and boots, with a black mask with two eyeholes. From that day, he was the assassin of pure bloodshed, the maniac of Chicago's streets. He was Oni-sash.
