When the Hulk was exiled to the Red King's planet, Korg became the Hulk's ally after he and five others were victorious during one of the gladiator games that rule on the planet as a form of entertainment. Korg was the first to let the group talk to each other, and after more victories in the game, Korg became a gladiator. Still fighting alongside the Hulk, Korg was part of the group that rebelled against the Red King after the Silver Surfer used his Power Cosmic to destroy the disks that controlled the slaves. The Surfer had also been made a slave by such a disk, but it was destroyed by the Hulk when they were forced to battle (in the film adaptation, it was Beta Ray Bill, not the Silver Surfer, using the lightning powers of his hammer, Stormbreaker, to perform this feat).
