Korg

Korg is a Kronan (a silicon-based rock-like alien) who ended up enslaved as a gladiator on the planet Sakaar, where he fought in the arena and eventually became a close ally of the Hulk, joining the loyal brotherhood known as the Warbound.

Few characters can claim a Marvel debut as storied as Korg's — first appearing in the legendary Journey into Mystery #83 in 1962, the very same Silver Age issue that introduced the world to Thor, making that single comic one of the most historically significant in the entire Marvel canon. Decades later, Korg found a whole new generation of fans through the explosive World War Hulk saga and its Warbound aftermath, sharing the page with the Green Goliath himself, Bruce Banner, and fierce companions like Hiroim, Miek, and Elloe Kaifi. With three key collector issues to his name and a publishing presence stretching across an remarkable 63 years from 1962 all the way to 2025, this is a character whose longevity speaks for itself. Whether you're a Silver Age purist or a modern Marvel devotee, Korg rewards the curious reader who digs in.
