Dark Zagi (ダークザギ, Dāku Zagi?) is a dark, evil, twisted, demonic clone of Ultraman Noa. He was created by a race of aliens known as The Visitors, who had hopes of creating their own protector after seeing the power Noa possessed. But something went wrong and Zagi turned on his creators, who in turn destroyed their home planet. Zagi then took an army of creatures known as Space Beasts and began a spree of universal destruction on any planet in his way.
