Zagi first appeared when he saved Thor and Rai. A few years after Thor became the Top of Ochre Ring, Zagi was known in Chimera as the White Wolf Demon, and was the Top of Blanc Ring. He and his Ring members massacred the people of Night Ring so that he could meet Thor. Zagi was loved by Karim, who was his Second. However, he noticed that Karim also loved Thor and ordered her to leave Blanc Ring.
