King Zarkon

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.
