The Hulk learns that Reed Richards and others conspired to keep him from returning to Earth. His ship crashes on the planet Sakaar, where he is captured and forced to fight as a gladiator for the amusement of the Red King, Emperor of Sakaar.
The Hulk forges alliances with several of his fellow gladiators, creating a mightier force that proves popular with the audience. An insurgency movement attacks the arena, offering Hulk and his new friends a chance to escape.
Caiera offers Hulk a way out of the arena but he refuses her. The Emperor's Death's Head guards attack the arena during a match, killing Captain Skee and forging an even stronger bond among the gladiators.
The Silver Surfer was drawn to Sakarr in a weakened condition and enslaved by the Emperor to fight the Hulk and his allies in the arena. The slaves are freed from the Emperor's control and revolt, tearing down the arena and escaping.
