Aurons life started when his mom and dad were killed in a bombing. His brother had to take care of him but soon followed with his brother going missing. Auron then discoverd he was more powerful then he could imagine. He had the abilitie to throw fire turn invisible. He had super strength speed and could glide threw the air. But he had a problem he was angry.. the angrier he was the stronger he became and this could endanger him. "I am alone in a world i dont know i have no one" this is the setenance that goes on in his head he doesnt know anything about the world yet nothing about his past rings a bell only his brother. He was attacked and put in a coma by an evil ShadowStrike ddx9 attack robot.
