King Zarkon

King Zarkon is the tyrannical alien ruler and primary antagonist of the Voltron universe, leading an empire of evil against the heroic Voltron Force. He commands fearsome Robeasts and allies himself with the dark witch Haggar in his relentless quest to conquer the universe.

Few villains in the Voltron universe loom as large as King Zarkon, the malevolent sovereign who burst onto the Bronze Age comics scene in Voltron #1 in 1985, brought to life by Henry Vogel and Dick Ayers. Across a remarkable span stretching all the way to 2025, this enduring antagonist has shared pages with the likes of the witch Haggar, Prince Lotor, Princess Allura, and the heroic Keith — not to mention the mighty Voltron itself — making his issues a who's-who of the franchise's most iconic figures. What makes Zarkon especially intriguing to collectors is his appearances in Crisis on Infinite Earths and All-Star Squadron alongside his home series, placing him in some of the most celebrated company in Bronze Age comics. With forty years of publication history behind him, he's a villain with genuine staying power — and a must-know name for any serious Voltron enthusiast.
