Mongul

Mongul is an alien warlord of immense physical power who lost dominion over his empire and became an interstellar conqueror driven to reclaim it, seizing control of Warworld—a massive, weaponized artificial planet—as the centerpiece of his brutal campaign to dominate the cosmos.

Few villains in the DC Universe carry themselves with the sheer, throne-claiming menace of Mongul, who stormed onto the Bronze Age scene in DC Comics Presents #27 in 1980, the creation of Len Wein and Jim Starlin. Over 45 years and 51 catalogued appearances — three of them recognized key issues — this tyrant has proven himself the kind of threat that puts Superman, Batman, and Wonder Woman in the same room just to deal with him. From DC Comics Presents to Adventures of Superman to Batman/Superman, Mongul has haunted the highest-stakes corners of the DC cosmos, a constant reminder that some enemies don't fade — they conquer. If you're building a serious DC collection, this is a name you don't overlook.
