No one really knows of Wolf's past. Everything is a mystery to him but for some reason he loves big blasts (Who doesn't?) he was granted his heartless powers by Ansem but ever since Ansem was destroyed he had forgoten what had happened, a man named Reon said he could make all the booms he wanted if wolf worked loyally towards him. Now Wolf is equipped with his END OF THE WORLD sword, he loves making the planets blow up.
