Nebula

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. Like Gamora, Nebula greatly despised her father, Thanos, for torturing her and turning her into a cybernetic assassin. However, despite this, she always tried, often in vain, to prove her worth to her father. Nebula lost any desire to do this after betraying Thanos, though, and since vowed to kill her adopted father, now free to express her hatred for him. Her hatred for Thanos eclipsed any fear she had of him, as she went as far as to infiltrate the heavily guarded Sanctuary II just to try to kill Thanos. This however failed miserably and she was captured and tortured badly by Thanos. This likely compounded her hatred for him even further and Nebula later immediately became furious and brutally attacked him unhesitatingly when he coldly told her he considered killing her would have been a "waste of parts." However, like Gamora, it would appear that as Thanos was the only parental figure she knew for the majority of her life, Nebula deep down did have some sentiment towards him, as she didn't look glad when Thor decapitated Thanos and even cried a bit. Nebula had very little loyalty to a cause as she quickly betrayed Thanos once Ronan the Accuser harnessed the power of the Power Stone, believing he could kill Thanos as he declared to do so. However, when the Battle of Xandar became too intense for her liking, she quickly abandoned Ronan to escape, despite her sister's pleas for her to help the Guardians of the Galaxy, becoming an independent criminal. Nebula is also known to be highly sadistic, even being referred to as the biggest sadist in the galaxy by Taserface and she seems to take pride in her sadistic killing of her targets, with her proudly telling Gamora that "The screams of my victims can be heard through the galaxy," which Gamora replied in stride by saying that it was because Nebula often took a long time to kill her foes because she tortured them first. Unlike her sister who seeks to atone for her past crimes, even after she had redeemed herself, Nebula shows no visible signs of regret for her own crimes and she was perfectly willing to murder anyone tasked to her and anyone who stood in her own way. However, she did say that she would help the universe by killing Thanos, indicating that after her reconciliation with Gamora, she not only saw Thanos' death as vengeance but also to save other children from suffering at his hands. Although she and Gamora grew to genuinely care for each other and develop a strong bond, ever since Thanos considered Gamora his favored children and Gamora's repeated victories over her (which caused her to be painfully cybernetically altered), Nebula grew to resent Gamora, both for never letting her win and for being Thanos' favored daughter. However, she does still like and care for her to an extent, as Nebula said she disliked and hated her the least out of all the other children of Thanos and she did not have the heart to let her be captured by Thanos and Ronan, as she knew that one of them would torture her first before killing her, causing her to genuinely believe that when she destroyed her ship and left her to die in space that she was doing Gamora a favor. However, while she ruthlessly tried to kill her sister when they fought in Ego, even dishonorably attacking Gamora despite Gamora saving her, when Nebula finally had the chance to kill her sister, she could not bring herself to do so and although she first revealed that she finally beat Gamora, Gamora's lack of care on it and admonishing her for still continuing their rivalry caused her to reveal why she hated her and this caused them to warm up with each other. Nebula finally forgave Gamora, even joining forces with the Guardians of the Galaxy and saving her. When Nebula departed from their company, she did so on equal terms, sharing a hug with her sister before she left. Her love for Gamora was shown when Gamora was taken by Thanos; when Nebula escaped, she sent a transmission to the Guardians where to meet her and told Star-Lord not to lose Gamora again or she would sew his face to his genitals and she took time to question Thanos on her sister's whereabouts and was absolutely distraught, losing her emotional composure and almost crying, as she realized he had sacrificed Gamora. She continued to mourn her sister's death even years later and having came to regret their past enmity, referred to this with visible shame and regret to the 2014 Gamora and acknowledged her as a true sister, successfully convincing Gamora's past self to work with her against Thanos. In addition to her sisterly bond towards Gamora having returned, in time, she came to trust and care for the Guardians, as she trusted them enough to tell them to meet her on Titan so they could fight Thanos and was visibly distraught as they ceased to exist, taking them to lay on the floor to mourn their and Gamora's demise and could not answer (only sadly looking away) when Rocket questioned on the other Guardians. She would eventually join the Guardians after they were restored. Although she didn't have much affection for Star-Lord - Gamora's boyfriend - as shown by how she threatened him a gruesome death for his inability to prevent Gamora from being taken by Thanos and later on simply said Gamora only picked him as her boyfriend as the only other choice she had was a tree, Nebula did have the heart to sympathize with him over Gamora's death, only indicating rather than actually saying outright that Gamora is dead. For Nebula, her reconciliation with Gamora and the events of the Infinity War have been enlightening journeys for her. Having long since been driven by her jealousy and rage towards Gamora and hatred towards Thanos, overcoming those issues has allowed her to move on with her life and truly become a much better person. This was shown by how rather than continuing to work as an assassin, Nebula instead decided to work as a member of the Avengers after the Snap and likewise she would join the Guardians of the Galaxy officially after the Blip and Battle of Earth, showing that she has lost most - if not all - of the killer instinct she was once so proud of herself for and has finally began to follow in Gamora's footsteps by similarly seeking atonement and a better life. She has become much more open, bonding with Tony Stark as they fixed a ship and left Titan, with her using her technology to treat Tony's wounds before they infect, and Tony acknowledging in a message intended for Pepper Potts that she would like the "only slightly sadistic" cyborg, having performed very affectionate acts for Tony, the main ones being when she wrapped a blanket around Tony and positioned him on a chair instead of on the cold floor and also offering food to Tony, and was open to War Machine's attempts to socialize over their respective cybernetics, and rather sentimental, solemnly recounting to the past Gamora of how they grew as sisters in the future. Her growth was most shown when she confronted her past self, hoping to sway her to join their cause by telling her of what she becomes in the future, only resorting to lethal force when she felt that there was no other choice. She has even displayed a subtle lightheartedness and a knack for dark humor, engaging in macabre but playful banter with her comrades in the Guardians upon reuniting with them.
