Ansem was formerly a respected sage and ruler of the Radiant Garden. As a researcher and ruler of his world, Ansem studied the heart and delved into the many secrets of the worlds. He and his apprentice, Xehanort, believed that darkness could spread into and take control of the heart. After meeting with King Mickey, Ansem ceased the experiments when he heard his research may be connected with a current crisis happening on other worlds. He later found his report on the experiments was given new entries by Xehanort, now using the name Ansem as his own. Ansem's apprentices then betrayed him and banished him to a world of nothingness before ending up in the Realm of Darkness, losing his memory in the process. However, regaining his memories, Ansem took on the name DiZ. From that point on, until he cleared his name and had his revenge, DiZ wore concealing red robes and covered most of his face with red bandages.
