Nebula

"Nebula... I was a child like you. I was concerned with staying alive until the next day, every day. And I never considered what Thanos was doing to you. I'm trying to make it right. There are little girls like you across the universe who are in danger. You can stay with us and help them." "I will help them by killing Thanos."

- Gamora and Nebula Nebula is a Luphomoid assassin, an adopted daughter of the intergalactic warlord, Thanos and adopted sister of Gamora. As the right-hand woman of Ronan the Accuser during his and Thanos' quest to retrieve the Orb, she helped him in the fight against the planet Xandar and the Guardians of the Galaxy. She vanished after a fight against her sister. Nebula soon afterwards was captured by the Sovereign and handed back to the Guardians. She escaped and helped Taserface lead the other Ravagers in a mutiny against their former leader Yondu Udonta before leaving to find and kill Gamora. After forgiving and helping her own sister alongside the Guardians during the Battle on Ego's Planet, she left in a ship to pursue a revenge mission against Thanos.

Nebula was eventually captured by Thanos, however, and used as a bargaining tool to convince Gamora to reveal the location of the Soul Stone. Escaping and then pursuing Thanos to Titan, Nebula learned that Thanos had killed Gamora and aided both the Guardians and members of the Avengers in combating Thanos. Despite their efforts, they failed to stop Thanos from obtaining the Infinity Stones, which he then used to wipe out half the universe's population. Nebula was among those who survived, but was left alone on Titan with Tony Stark. She and Rocket Raccoon are currently the remaining members of the Guardians of the Galaxy.

Trained for Thanos
"My father would have Gamora and me battle one another in training. Every time, my sister prevailed. My father would replace a piece of me with machinery, claiming he wanted me to be her equal. But she won. Again, and again, and again, never once refraining."

- Nebula

Nebula was one of many youths who were orphaned and then taken in by the interplanetary warlord Thanos to be trained as merciless warriors devoted to his service. While Nebula greatly despised her other adopted siblings, she formed a genuine bond with the Zehoberei Gamora to the point that they began to truly consider each other as sisters. Throughout her childhood, Nebula trained to be a galaxy-class killer under the tutelage of Ronan the Accuser. Nebula would often train alongside Gamora and fellow Thanos devotee Korath. Thanos regularly had Nebula spar with Gamora to test their strengths with Gamora winning every match. Every time Nebula lost, Thanos would upgrade her to try and make her Gamora's equal. Nebula grew to resent Gamora for never letting her win causing Thanos to torture her.

One training scenario on the arboreal world of Dervani saw Nebula and Gamora pitted against each other in a competition to retrieve a data ingot for Ronan. The girls sparred on the surface, leading to Gamora throwing Nebula off a cliff, severely injuring her and requiring multiple cybernetic replacements in order for her to live. Upon reaching adulthood, Nebula and Gamora served Thanos under the command of Korath the Pursuer. On a mission to locate the Orb on the planet Praxius IX, inside of one of the Cloud Tombs of Praxius, Nebula went in without waiting for Gamora and fell into a trap. Ensnared by an impenetrable Laser Thorn Energy Net, Nebula found herself at the mercy of the inhabitants and needed to be rescued by Gamora. Never one to tolerate failure, Thanos ordered Gamora to leave Nebula behind, with only a sharp blade to free herself. Nebula was forced to amputate her own arm in order to escape the netting.

Following Ronan's Orders
"You think I don't know? You would keep me from advancing! You would have Ronan tell father only Gamora furthers his great plan!" "I will keep you alive!" "Compassion? What would Ronan say to that?"

- Nebula and Gamora

Thanos lent Nebula and Gamora to the Kree warmonger Ronan the Accuser, who made a deal to retrieve the Orb for Thanos so he would in turn destroy Xandar. When Korath the Pursuer reported that he had failed to retrieve the Orb on Morag, thanks to Star-Lord's intervention, Nebula was tasked to retrieve the Orb from Star-Lord. Nebula told him it would be an honor, but Gamora insisted that she follow Quill as she knew Xandar. Ronan agreed and Gamora went on the mission. When they left the meeting, Nebula confronted Gamora and they had a brief argument where they tried to break each other's fingers. Nebula accused her sister of now attempting to become Ronan's favorite and they argued over who was the superior killer. When Nebula mentioned that the screams of her victims could be heard across the galaxy, Gamora replied that it was because she took too long to kill them before walking away from Nebula. When Ronan and Nebula received word that Gamora had betrayed them only to be sent to the Kyln with the Orb, The Other demanded they travel to the Sanctuary to discuss this with Thanos. There, Nebula repaired her cybernetic arm while Ronan argued with The Other, only for Ronan to snap his neck. Thanos responded by threatening Ronan if he failed again. As they left, Nebula assured Ronan that he would not win a fight with her father. When they arrived at the Kyln, they discovered Gamora had already escaped with the Orb, with the help of Star-Lord and others. Ronan's soldiers took over the prison and Nebula tortured a Nova Guard to gather more information. She received a message on her cybernetics that the Nova Corps were on their way to defend the prison. As they were leaving Ronan ordered Nebula to send their Necrocraft across the galaxy to begin the search for Gamora and to cleanse the prison, murdering all of the guards and the prisoners.

Skirmish on Knowhere
"You are a disappointment sister; out of all our siblings, I hated you least." "Nebula, please. If Ronan gets this stone he’ll kill us all." "Not all. You will already be dead."

- Nebula and Gamora

Following the orders of Ronan the Accuser, Nebula and Korath the Pursuer continued their search for the Orb across the galaxy onboard the Dark Aster, until they received a message from Drax the Destroyer telling them it was on Knowhere where they went to recover it. Upon arriving onboard Necrocraft and their army of Sakaarans, they were spotted by Gamora and her new team, who escaped into a Mining Pod while Nebula gave chase with her small army.

While Ronan began fighting with Drax, whose wife and daughter had been killed by the Kree, Nebula lead a squad of soldiers in fighters to chase Gamora across Knowhere, while fighting off Star-Lord and Rocket Raccoon who defended their ally. Eventually, Gamora was forced to head into deep space which shut down her pod. Nebula destroyed her ship, despite her pleas, and leaving her for dead in space and retrieved the Orb for her master Ronan. Both Nebula and Korath the Pursuer were present when Ronan the Accuser told Thanos he was aware of the Orb's nature as one of the Infinity Stones. Ronan ripped open the Orb and harnessed its power, becoming the most powerful being in the universe. Ronan told Thanos he would destroy Xandar and then find and destroy The Mad Titan. Nebula offered her total loyalty to Ronan should he succeed, swearing to help him destroy a thousand planets.

Battle of Xandar
"The starboard kern has been breached! We have been boarded!" "Continue our approach." "But the Nova Corps have engaged!" "None of that will matter once we reach the surface."

- Nebula and Ronan the Accuser

When they arrived on Xandar, a fleet of Ravagers lead by Yondu Udonta and Star-Lord engaged them. The fleet fired a blot of flame to disguise their moves, but Nebula saw that they had dived under the ship and she ordered all their fighters to destroy the ships. Once they received word that the side of the ship had been breached, Nebula tried to convince Ronan the Accuser to retaliate but he refused, stating that his focus was to land on the planet's surface so he could finally destroy it. Deciding to take matters into her own hands, Nebula took a squad of soldiers with her to engage the attackers before shutting the door, locking in Ronan. When Star-Lord, Gamora, Rocket Raccoon and Drax breached the ship, Nebula confronted them. As Nebula began to insult her former sister she was silenced when Drax shot her with a rocket, sending her flying backwards and damaging her body while allowing the Guardians to continue on their mission.

Duel against Gamora
"Sister! Help us fight Ronan! You know he is crazy!" "I know you're both crazy."

- Gamora and Nebula

The shot fired by Drax the Destroyer caused Nebula's entire body to be damaged, but her cybernetic implants helped to repair her within moments, twisting her arm and jaw back into place. Once she was repaired Nebula began to fight Gamora, using her electrified batons against Gamora's Godslayer. During their fight against each other, the side of the ship was suddenly torn apart by an explosion as the Battle of Xandar between the Ravagers and the Sakaarans continued on. During their fight, Gamora attempted to unlock an armored door to assist the Guardians of the Galaxy, however Nebula did all she could to delay this action. Eventually, Nebula managed to gain the upper hand by disarming Gamora and then using her batons to electrocute Gamora, nearly killing her. However Gamora regained her strength and knocked her outside of the hole in the Dark Aster and leaving Nebula hanging onto the edge of the hole. As Nebula hung hundreds of feet above Xandar's surface, with her hand trapped onto a spike, Gamora tried to convince her to fight against Ronan the Accuser, claiming Ronan was crazy. But Nebula refused, citing they were both crazy and cut off her cybernetic hand. However, instead of falling from the sky to her death, she landed on top of a Ravager's M-ship. Nebula then threw the pilot out and took control of the ship before flying it far away from the battle.

Captured by the Sovereign
"I understand she is your sister?" "She is worth no more to me than the bounty due for her on Xandar."

- Ayesha and Gamora

Some time later, Nebula was arrested by Ayesha and the Sovereign for trying to steal expensive Anulax Batteries. Six months after the Battle of Xandar, the Guardians of the Galaxy took custody of her to hand over to the Nova Corps. As the Milano piloted away, Nebula was handcuffed inside the ship and demanded food being ignored by the Guardians. While still locked up Nebula continued to mock Gamora for joining the Guardians before demanding that she be fed some fruit, which Gamora refused to give her, claiming the fruit was still not ripe enough. When the Sovereign fleet attacked after Rocket Raccoon stole the batteries, Nebula was almost sucked out of the ship but escaped her restraints. Her hands remained handcuffed and she demanded to be released after they crashed on Berhert to fight whoever was in the unidentified craft, with Nebula surviving the crash with the others.

Deal with Taserface
"Well, hello boys. Blah, it's not ripe."

- Nebula to the Yondu Ravager Clan

Nebula witnessed Ego's revelation that he was Star-Lord's father. The next day she was left in the Milano with Rocket Raccoon and Groot whilst Gamora, Quill and Drax the Destroyer went with Ego and Mantis. When Yondu Udonta and the Ravagers attacked the Milano, she managed to persuade Groot to release her before shooting Yondu's fin and then shooting Rocket in the chest. She was taken aboard Yondu's ship witnessing the mutiny led by Taserface before demanding ten percent of the bounty Ayesha had placed on the Guardians of the Galaxy as well as 'some other things'. Nebula was given a new cybernetic arm by Kraglin Obfonteri as well as an M-ship. She informed him of her upbringing with Thanos and how he had 'upgraded' her every time she lost a sparring match to Gamora. Nebula explained that after she killed Gamora she would use her ten percent to buy every ship she could to kill Thanos.

Fight with Gamora
"I'm not the one who just flew across the universe just because I wanted to win!" "Do not tell me what I want!"

- Gamora and Nebula

Nebula flew to Ego the Living Planet and began firing at Gamora pursuing her into caverns before being trapped as her M-ship prepared to explode. She was rescued by her sister but instead of being grateful attacked her sister but couldn't kill her. The pair formed an uneasy alliance after Nebula revealed her anger at Gamora's attitude during their upbringing.

The two sisters walked through the caverns and discovered a large pile of bones.

Battle on Ego's Planet
"This is gonna hurt!" "Promises, promises."

- Yondu Udonta and Nebula

Nebula and Gamora rushed back to the palace and confronted Mantis who agreed to help them. Along with Drax the Destroyer, they burst into the main hall to find Ego attacking Star-Lord before a ship piloted by Yondu Udonta and Rocket Raccoon crushed him. Nebula agreed to help as the Guardians were her only ride off of Ego. During the Battle on Ego's Planet, she wired the ship up to her cybernetic arm to provide power to the lasers which electrocuted her and caused her great pain but destroyed the Sovereign fleet in the process. When the ship was destroyed she joined the Guardians of the Galaxy in the heart of the planet to continue the fight. When Ego attacked, Nebula saved Gamora from falling to her death with the sisters climbing back up to the fight before being trapped and suffocated in organic matter. When Star-Lord took control, they were both released, which allowed them to reach the ship piloted by Kraglin Obfonteri.

Reconciling with Gamora
"You will always be my sister."

- Gamora to Nebula

Nebula prepared to leave during Yondu Udonta's funeral. Despite Gamora's attempts to persuade her into joining them, she chose to leave and try to kill Thanos instead and prevent other people's daughters from sharing the same fate she has suffered. The two sisters hugged before Nebula departed.

Futile Vengeance
"Some time ago, your sister snuck aboard this ship to kill me. Very nearly succeeded."

- Thanos to Gamora

Four years following the battle with Ego, Nebula attempted to kill Thanos by sneaking onto the Sanctuary II. She nearly succeeded, but was caught by her former master and put in a torture chamber, where her cybernetic parts were pulled apart from her body, causing immense pain. When Thanos captured Gamora after she attempted to stop him on Knowhere, he brought her to Nebula to force her to reveal the location of the Soul Stone. Thanos began torturing Nebula again, tearing the cybernetic parts from her body using the Infinity Gauntlet, in an attempt to get the information from Gamora. Gamora at first resisted, claiming she didn't know the location of the Soul Stone. Thanos, who knew that Gamora was lying, played a clip from Nebula's memory using a projector in her cybernetic parts. The clip showed Gamora having a conversation with Nebula, in which Gamora stated that she found the map to the Soul Stone, but decided to burn it to ash to prevent Thanos from finding it. After commenting on how poor of a liar Gamora was, Thanos started ruthlessly torturing Nebula again, until Gamora gave in and told Thanos the location of the Soul Stone: Vormir. When Thanos and Gamora left, one of his henchmen began putting Nebula back together. Seizing a quick opportunity, she killed the henchman and made a quick escape from her captivity. Nebula contacted Mantis, requesting her and the rest of the Guardians of the Galaxy to meet her on Titan, knowing that the members of Thanos' Black Order would meet him there once they found the Time Stone and Mind Stone. Getting inside a Necrocraft, she flew to Titan with the desire to enact her plan to kill Thanos.

Battle of Titan
"You should have killed me." "It would have been a waste of parts!"

- Nebula and Thanos

When she arrived on Titan, the Guardians of the Galaxy were fighting alongside Iron Man, Spider-Man, and Doctor Strange in a battle with Thanos. Nebula crashed the Necrocraft into Thanos, then exited the spacecraft and attacked him with an electrified staff. She furiously told him that he should have killed her, to which Thanos coldly remarked that it would have been a waste of parts. As she continued to fight him, Nebula demanded to know where Gamora was. Although she fought ferociously, Nebula would prove to be no match for Thanos, and was quickly thrown backwards into a pile of rocks. The Guardians and Avengers then restrained Thanos, with Mantis successfully putting him into a paralyzed and sleepy state. Star-Lord then asked Thanos where Gamora was. Realizing that Gamora had not returned with Thanos from their trip to Vormir, Nebula then began to tear up, realizing that Gamora was likely killed by Thanos. She told this to Star-Lord, and Thanos confirmed that it was true by muttering that he had to kill her. Stricken with grief, Star-Lord began to punch Thanos' face with his blaster in a state of blind fury, weakening Mantis's grip on Thanos. Despite Iron Man's attempts to hold Star-Lord back, it was too late; Thanos was able to break free and overpower the Avengers and Guardians. After escaping, Thanos blasted Drax, Star-Lord, and Nebula with a burst of energy from the Power Stone, leaving the three of them unconscious. Thanos then pulled chunks of Titan's moon down from orbit, causing a meteor shower to engulf the planet. Nebula, Drax, Star-Lord, and Mantis all began to lifelessly float in the air due to Titan's fluctuating gravity and the intense impact from the meteors. Nebula was presumably saved by Spider-Man, who had also saved Star-Lord, Drax the Destroyer, and Mantis by adhering them to a floating rock with his webbing. After successfully besting Iron Man and Doctor Strange, Strange gave Thanos the Time Stone so that he would spare Stark's life, saying that the Avengers were now in the end game. Thanos then left Titan in pursuit of the final Infinity Stone, the Mind Stone, on Earth.

Thanos' Victory
"He did it..."

- Nebula to Tony Stark

While he was on the Earth, Thanos had successfully got the Mind Stone and, using the full Infinity Gauntlet, snapped his fingers, wiping out half of all sentient life in the universe. Nebula, having survived the snap, grimly watched as the Guardians of the Galaxy as well as Doctor Strange, and Spider-Man had all perished and faded into ash as a result of Thanos' victory. Nebula told Tony Stark that Thanos had succeeded in his mission, with visible despair on her face. She then sat on the ground as she grieved Gamora's death and Thanos' victory.

Personality
"You were the one who wanted to win, and I just wanted a sister! You were all I had, but you were the one who needed to win. Thanos pulled my eye from my head. and my brain from my skull, and my arm from my body... because of you."

- Nebula to Gamora

Like Gamora, Nebula greatly despises 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 has 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, which 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".

Nebula has very little loyalty to a cause as she quickly betrayed Thanos once Ronan the Accuser harnessed the power of the Orb, 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.

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 had grown 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 either Ronan or Thanos 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 furiously reveal why she hated her and this caused them to warm up with each other, with Nebula finally forgiving 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.

Years later, Nebula's relationship with Gamora and the Guardians appears to have improved considerably, as she trusted the Guardians enough to tell them to meet her on Titan so they can fight Thanos. Her care for Gamora was most notably shown when she furiously dueled with Thanos, she angrily asked where Gamora was. Upon realizing that Thanos had sacrificed Gamora, Nebula was visibly distraught as she implied it and seemed to show some sympathy towards Star-Lord, Gamora's boyfriend, showing more emotional sensitivity, as rather than bluntly telling him Gamora had died, she never actually openly said it and looked almost in tears when Star-Lord, in denial of Gamora's death, angrily asked Thanos to tell him that she was lying. She showed genuine care for the Guardians, looking visibly distraught as they ceased to exist.

Powers

 * Luphomoid Physiology: Nebula possesses natural higher physical capabilities beyond any human being, which are further enhanced by her physiological enhancements.
 * Superhuman Strength: Nebula has higher levels of superhuman strength, much greater than that of a human being. She managed to throw a pilot of an M-ship out of the vehicle in mid-air with ease and managed to temporarily overpower Gamora after the two of them survived an explosion. She was also able to easily snap the neck of a Chitauri soldier with one arm, even while weakened due to prolonged torture at Thanos' hands. Nebula was even able to slightly stagger Thanos with a punch and several baton strikes, although Thanos soon easily overtook and send her flying with a punch.
 * Superhuman Durability: Nebula can easily withstand multiple injuries, especially impact trauma, such as falls from great heights. While her body was contorted by being blasted with Drax the Destroyer's cannon at point blank range, she was otherwise unharmed and her cybernetic implants twisted her body back into place. She managed to jump onto a M-ship from several stories without withstanding injuries and survived being inside an exploding ship before landing on her feet several stories down unharmed. When plugging her mechanical arm into the ship to power the ship's energy beams, she was electrocuted and experienced great pain, but otherwise survived. She even managed to survive a powerful blow from Thanos and later a shockwave from the Infinity Gauntlet.
 * Superhuman Agility: Nebula has agility and coordination greater than that of a human being, allowing her to easily keep up with Gamora in a fight and dodge her sister's attacks.
 * Cybernetic Enhancements: Nebula's bionic enhancements are more extensive than that of her adopted sister, Gamora, allowing her further abilities.
 * Regenerative Healing Factor:Nebula-Broken-Jaw.png Nebula's extensive cybernetic implants allow her to quickly heal from otherwise near-fatal injuries, such as when her body was crushed and mangled when withstanding a direct blow from Drax's cannon. Thanks to her implants, she was able to reshape her body back to its original form by snapping her arms and jaw back into their normal place. Nebula was able to reshape her body after the impact of an exploding M-ship.
 * Concussive Energy Blast Generation: Nebula’s cybernetic arm allows her to fire concussive electroshock charges from her hand towards her enemies or over a specific target area.

Abilities

 * Master Assassin: Ever since she was a child, Nebula has trained extensively as an assassin under Thanos. She trained with Gamora throughout her childhood, but Nebula stated that she was not as skilled as her sister. Despite that, Nebula was skilled enough that even Thanos commented Nebula almost succeeded in killing him after sneaking into his spaceship.
 * Expert Combatant: As a highly trained assassin of Thanos, Nebula is very proficient in armed and unarmed combat. Nebula's skill in combat allowed her to compete with "the deadliest woman in the galaxy," Gamora, for a prolonged amount of time and even managed to defeat her when both were wounded after escaping an explosion, although it should be noted that Gamora was weakened more than Nebula was due to Nebula's more extensive cybernetics and the fact that Gamora had not been fighting to kill, but was trying to reason with Nebula, thus she was holding back. Her most impressive display of skill was seen when she briefly fought Thanos one-on-one, as although she was eventually no match for her far stronger and more experienced father, Nebula was still able to fare better than Drax the Destroyer as well as Doctor Strange, able to briefly pressure and land two blows on Thanos whereas Drax and Strange had difficulty fighting Thanos even with a web cotton hampering Thanos's eyesight and could not a land single hit in said occasion, although Thanos was briefly distracted by her mentions of Gamora and soon easily knocked her aside.
 * Staff Mastery: Nebula is highly accomplished in using sticks, her retractable electric batons being her preferred weapon. Using her staff, she was able to contend with Gamora using her sword and even managed to disarm her. Later, she was able to briefly force Thanos to the defensive and land some blows until she was inevitably defeated easily.
 * Expert Pilot: Nebula is an excellent pilot, with Gamora acknowledging her as being better and more knowledgeable at piloting than her, capable of easily flying a Necrocraft and an M-ship with great efficiency. During the Skirmish on Knowhere, Nebula was able to maneuver around Gamora's mining pod with ease and eventually shoot her ship down.
 * Expert Marksman: Nebula is a very accurate marksman skilled in sharpshooting. During the Attack on Berhert, Nebula was able to accurately shoot off Yondu Udonta's Yaka Arrow Controller before incapacitating Rocket Raccoon.

Cybernetic Enhancements
In her early years under Thanos' wing, Nebula received various upgrades that allowed her to gain extensive cybernetic properties and body features.
 * Cybernetic Arm:
 * Tempersteel Claws:
 * Cybernetic Message Receiver: Nebula had a cybernetic message receiver planted on her, which she used to alert the Saakarans that Gamora had the Orb, and to directly confront her shortly thereafter.
 * Contact Whiplash

Weapons

 * Electric Blaster: Nebula’s current weapon is a blaster which can fire blasts of electricity to electrocute and stun its targets, knocking them unconscious. She used it on Rocket Raccoon and Yondu Udonta to escape Berhert.
 * Electroshock Batons: Nebula's weapon(s) of choice are baton-like electroshock weapons which can be combined to form a longer electroshock staff.
 * Godslayer: During their skirmish on Ego the Living Planet, Nebula took Gamora's sword Godslayer and attempted to kill her sister with it, however she chose not to.

Vehicles

 * M-ship: After being defeated in combat by Gamora during the Battle of Xandar, Nebula was left hanging hundreds of feet above Xandar's surface, with her hand trapped onto a spike on the outside of the Dark Aster. Gamora tried to reason with Nebula but Nebula refused and cut off her cybernetic hand. Instead of falling from the sky to her death, she landed on top of a Ravager's M-ship. Nebula then threw the pilot out and took control of the ship before flying it far away from the battle. She would later used another M-ship to fly to Ego to try to kill Gamora, she crashed the ship during her fight with Gamora.
 * Milano: Nebula was held prisoner on the Milano after being captured by the Guardians of the Galaxy before it crashed on Berhert.
 * Necrocraft: After escaping captivity on Sanctuary II, Nebula stole a necrocraft and used it to go to Titan and crashed the ship onto Thanos in an attempt to kill him, interrupting his battle with the Avengers and Guardians, although Thanos was uninjured.

Trivia

 * Nebula's appearance in the movie seems to be based more on her second incarnation from the comics.
 * In the Guardians of the Galaxy Prelude, Nebula loses her entire left arm and has it replaced by cybernetics; however, in Guardians of the Galaxy, her left hand appears to be made of flesh.

Behind the Scenes

 * revealed she was up for the role of Nebula.
 * Karen Gillan stated that "I think she's a really interesting character. What I like to play around with is how jealous she is. She's Gamora's sister, and there's a lot of sibling rivalry. That's the most interesting aspect to me, because jealousy can consume you and turn you bitter, and ugly. And she's a total sadist, so that's fun too."
 * Karen Gillan also said, "She is very sadistic and evil, but I like to think for a very valid reason."
 * Monique Ganderton, Olivia Jackson, Kelly Richardson, Amy Lynn Tuttle, Shauna Galligan and Joanna Bennett were stunt doubles for Karen Gillan in the role of Nebula.
 * Collette Von Tora and Caileigh Scott were stand-ins for Karen Gillan in the role of Nebula.
