Considered too dangerous to remain on Earth, Hulk is sent into space by a group of heroes hoping to exile him to an uninhabited planet. But the journey goes off course and he crashes on Sakaar, a brutal world ruled by an authoritarian empire. Captured and enslaved, Hulk is forced to fight in arenas where he quickly becomes a feared warrior and then a symbol of hope for the oppressed. Surrounded by new allies, he is drawn into a rebellion that forces him to choose between his anger, his desire for freedom, and the responsibility of a world beginning to see him as far more than a monster.
