Guardians of the Galaxy 2

The Avengers decide the Hulk is too dangerous to remain on Earth.They trick him into entering orbit to destroy a rogue satellite, and then use a shuttle to jettison him from the solar system. They intended for him to land on a peaceful planet, but the shuttle passes through a wormhole on its way.

As Hulk listens to a recording from the Avengers explaining their actions, his shuttle crashes on the planet Sakaar. Weakened from the crash, Hulk is fixed with an obedience disk and taken into slavery. He is forced to fight gladiator battles for the planet's emperor, the Red King. It is here that Hulk meets the Guardians of the Galaxy who have also been taken into the arena and they form an alliance. Hulk becomes a popular hero for his actions in the arena, and a group of insurgents try to recruit the Hulk to their cause. The Hulk declines, but Gamora chooses to go with the rebels. During their next gladiator fight, a prisoner who has befriended the team named Lavin Skee is killed. As the others come closer to winning their freedom, the Red King's lieutenant, Caiera, arranges for them to fight the Silver Surfer, who is also controlled by an obedience disk. During the battle, the Hulk breaks the Silver Surfer's disk, freeing him. The Silver Surfer then destroys all the obedience disks of everyone in the arena. As he leaves Sakaar, he offers to return Hulk and Quill to Earth. They both choose to stay behind. The Hulk and the Guardians, now on the run from the Red King, are hunted by Caiera. As they travel through villages, Hulk finds followers who believe he is the foretold savior, "Sakaarson." Hulk denies this title. Caiera finally confronts the Hulk, their battle is interrupted by an invasion of "spikes" that cause monstrous mutations and death to anyone they touch. Caiera calls the Red King for assistance and learns that he ordered the spikes to be deployed there. Horrified at what her king has done, Caiera joins the Hulk and the Guardians. Hulk leads a raid on the Red King's capital, culminating in a one-on-one battle between the two of them. The Red King is defeated, and Hulk is named the new king. He takes Caiera for his wife, and the two are able to broker peace among the various conflicts which had festered under the Red King. Caiera becomes pregnant with Hulk's child. Meanwhile, the shuttle that brought Hulk to Sakaar is being turned into a monument. As part of its self-destruct sequence, the antimatter warp core engine detonates in a massive explosion. The whole city is destroyed, and Caiera dies. Enraged and blaming the Avengers who built the shuttle for the damage, Hulk and the Guardians leave Sakaar and head for Earth.
