Rocket Raccoon

Rocket Raccoon is a genetically and cybernetically enhanced raccoon turned freelance mercenary turned member of the Guardians of the Galaxy. She is considered to have one of the best tactical minds in the galaxy. She hails from Halfworld in the Keystone Quadrant, where machines were able to turn animals into sentient beings

Naming herself Rocket, she befriended fellow captive Halfworlders Lylla, Teefs and Floor, with the four believing they would soon be allowed to live in peace on a new planet. While aiding High Evolutionary in perfecting his experiments, Rocket discovered that she, along with her friends, were slated to be killed. Rocket attempted to free her friends, only for High Evolutionary to kill Lylla. Rocket then attacked her former master, mutilating him, which inadvertently resulted in the deaths of Teefs and Floor. Afterwards, Rocket boarded a ship and fled into the cosmos.

While traveling the galaxy, Rocket befriended Groot, and the pair committed crimes and picked up bounties. In 2014, they met Star-Lord, who convinced them to assist him in selling the Orb, which was being sought after by Ronan the Accuser, for a massive profit. However, when they discovered that the Orb contained the Power Stone, Rocket was convinced to risk everything to stop Ronan's plans from using the Infinity Stone to destroy Xandar. During the Battle of Xandar, Rocket managed to assist her friends in destroying Ronan, although this resulted in Groot being killed. Rocket then became a member of the Guardians of the Galaxy alongside the newly planted baby Groot.

Rocket continued working with the Guardians when they were hired by the Sovereign to slay an Abilisk. However, Rocket took the job as a way to steal Anulax Batteries with the intention to later sell them. This angered Ayesha, causing her to declare war on the Guardians and hire the Ravagers to capture them. Rocket and Groot were soon captured by Taserface under Yondu Udonta's command, forcing Rocket and Udonta to work together in order to break free and kill Taserface. During her time with Udonta, Rocket learned how to better herself and wishing to save her Guardians family, joined Udonta during the Battle on Ego's Planet.

Four years later, the Guardians rescued Thor after the Asgardians were slaughtered by Thanos, who had initiated the Infinity War. The Guardians split up; while the rest of the team returned to Knowhere to find the Reality Stone, Rocket and Groot accompanied Thor to Nidavellir to obtain Stormbreaker. Using the Bifrost Bridge, the trio traveled to Earth to join the Battle of Wakanda, where he fought alongside Winter Soldier. Their efforts to stop Thanos were unsuccessful, and Rocket was one of the only Guardians to survive Thanos' subsequent mass slaughter, along with Nebula. Rocket joined the Avengers on their trip to the Garden, where she witnessed Thor decapitate Thanos.

Rocket spent the next five years as a member of the Avengers under the command of Natasha Romanoff. In 2023, after discovering how to traverse through time safely, Rocket and Thor traveled back in time to 2013, where she extracted the Aether from Jane Foster on Asgard. With all six Infinity Stones used to resurrect the victims of the Snap, Rocket participated in the Battle of Earth against an alternate Thanos and his army. After attending Iron Man's funeral, Rocket left the Avengers and rejoined the Guardians, preparing to leave Earth and return to their cosmic adventures.

Rocket and the Guardians went on several missions with Thor, including the Battle of Indigarr. However, following the threat of Gorr the God Butcher, Thor left the team to help the Asgardians while Rocket and the other Guardians returned to the cosmos. After buying Knowhere from the Collector, Rocket worked with Cosmo to rebuild it, and on one occasion, they celebrated Christmas with Kevin Bacon.

Rocket is also in denial about being a raccoon and goes as far as saying she doesn’t know what a raccoon is
