Nebula

*"Thanos spent a long time trying to perfect me. And when he worked, he talked about his great plan. Even disassembled, I wanted to please him."*
―Nebula to the Avengers[src]**Nebula** is a former Luphomoid assassin, an adopted daughter of Thanos and adopted sister of Gamora. Together with Gamora, Nebula was assigned to Ronan the Accuser, during his quest to retrieve the Orb, although Gamora eventually betrayed them. Due to her hatred of Thanos, Nebula joined Ronan when he betrayed Thanos and tried to use the Power Stone by himself to destroy Xandar. During the Battle of Xandar, Nebula fought against the Guardians of the Galaxy but was forced to retreat from the battle. Later, Nebula was captured by the Sovereign and handed back to the Guardians, although she was able to escape and help Taserface in a mutiny against Yondu Udonta. Nebula then attempted to kill Gamora but they reconciled, so she helped the Guardians in their fight against Ego.

Nebula pursued her revenge mission against Thanos and even was able to infiltrate the *Sanctuary II*, but her attempt to kill him was failed. Thanos captured and tortured Nebula, using her as a barganing tool to force Gamora to reveal the location of the Soul Stone. Nebula managed to escape and regrouped with the Guardians of the Galaxy and the Avengers on Titan, during their battle against Thanos, before she realized that he killed Gamora to get the Stone. The battle was eventually won by Thanos, who reached his goal and used the Infinity Stones to wipe out the half of the universe's population, as Nebula was within survivors. She and Tony Stark wandered in space onboard of the *Benatar*, awaiting their demise, before they were rescued by Captain Marvel.

As Thanos was eventually slained by Thor, Nebula and Rocket Raccoon joined the Avengers to uphold the order in the galaxy, while most of the Guardians of the Galaxy were gone. Five years later, Nebula participated in the Time Heist, as the Avengers attempted to get the Infinity Stones from alternate timelines and revert the Snap. Together with War Machine, Nebula retrieved the Power Stone, however, she got captured by the alternate Thanos, who found out about her universe and sought to bring his army there. Nebula was able to convince the alternate Gamora to turn against Thanos, and together, they participated in the final Battle of Earth, during which Nebula killed her alternate self to save Gamora and Hawkeye. As Iron Man sacrificed himself, Thanos and his entire army were eliminated, and Nebula attended his funeral to honor him.

Together with Rocket Raccoon and Thor, Nebula parted ways with the Avengers and rejoined the Guardians of the Galaxy. They continued to help those in need, such as Indigarrians during the Booskans' attack, although Thor separated from them to stop Gorr the God Butcher. A year and a half later, Nebula helped rebuild Knowhere and celebrated Christmas with the Guardians and Kevin Bacon.
