Dark Zagi "Ultinoid Zagi "

About

Dark Zagi, originally known as Ultinoid Zagi (ウルティノイド・ザギ), is a demonic clone of Ultraman Noa and the main antagonist of Ultra N Project. He was created by a race of aliens as a biological weapon against malevolent creatures called Space Beasts until Zagi turned on his creators, which they tried to end him by destroying their home planet but failed. Zagi then took an army of Space Beasts and began a spree of universal destruction on any planet in his way.
