1. Guardians of the Galaxy

However as it was discovered that the Orb was one of the Infinity Stones which was being sought out by Ronan the Accuser, Rocket was convinced to risk everything to stop Ronan's plans to destroy Xandar and enslave the world.

During the ensuing conflict, Rocket managed to assist his friends in destroying Ronan, despite Groot seemingly being killed. He then became a member of the Guardians of the Galaxy alongside the newly planted baby Groot.

2. Guardians of the Galaxy Vol. 2

Rocket continued working with the Guardians when they were hired by the Sovereign to slay the Abilisk, however Rocket took the job as a way to steal Anulax Batteries to sell. This angered Ayesha who declared war on the Guardians, hiring the Ravagers to capture them.

Rocket and Groot were soon captured by Taserface, who had taken command from Yondu Udonta, which forced Rocket and Udonta to work together to break free and kill Taserface.

During his time with Udonta, Rocket learned how to be a better person and understood how much he loves his Guardians family, so he joined the fight against Ego, the father of Star-Lord, losing Udonta during the battle.

3. Avengers: Infinity War

Four years later, the Guardians picked up Thor after he and his people were attacked and slaughtered by Thanos, who had resumed his quest for the Infinity Stones himself.

The Guardians split up in order to procure different stones; while the rest of the team returned to Knowhere to find the Aether, Rocket and Groot accompanied Thor to Nidavellir to obtain the weapon Stormbreaker.

The trio then headed to Earth where they helped the Avengers in defending Wakanda from Thanos' minions. Their efforts to stop Thanos proved for naught in the end, and Rocket was one of the only Guardians to survive Thanos' subsequent mass slaughter, along with Nebula.
