Yuga Khan is a DC Comics supervillain. He first appeared in New Gods volume 2 #17 (June 1990). Khan was former patriarch of Apokolips, whose misguided attempt to unravel the unknowable mystery of the Source left him a helpless captive for countless thousands of years. Yuga Khan's wife Heggra later died by the hand of their son Darkseid, who took control of Apokolips himself. Using his planet-rending powers, Khan eventually freed himself; he then returned to Apokolips where he easily overthrew his son Darkseid from the throne - until he was reclaimed by the Source in the Promethean Galaxy.
Yuga Khan was the most powerful New God. He possessed enormous physical prowess, the ability to traverse hypertime, and could manipulate The Source itself.
