Gamora

"Quill, I have lived most of my life surrounded my enemies. I will be grateful to die among my friends."

- Gamora to Peter Quill

Gamora is one of the main characters in Marvel Cinematic Universe's Guardians of the Galaxy. She is the lover of Peter Quill and former adoptive daughter of Thanos and the adoptive sister of Nebula who becomes a member of the Guardians of the Galaxy. She was sacrificed by Thanos for the Soul Stone.

Life on Zehoberei
Gamora, as a young girl, loved her biological parents very much. Her father was often never involved in diplomacy.. However, her relationship with her family did not last forever. The Mad Titan Thanos had his minions kill half of the Population on Gamora's planet and came to adopt her because of her free spirit. Thanos kept her distracted from the oncoming slaughter by teaching her about balance with a knife.

Raised by Thanos
Alongside Nebula and the Black Order, Gamora would become an assassin and her body was physically enhanced by her father as she grew older.

Thanos abused his daughters, often making Gamora and Nebula fight in combat and the latter of the two would fail while the other prevailed and Gamora, often fighting for her life, bested Nebula in combat. However, Gamora never took into account what her sister was feeling. Throughout the years, Gamora killed without mercy, earning a reputation as the "Deadliest Woman in the Galaxy." Eventually tiring of this life

Guardians of the Galaxy
Gamora was on the spaceship when Ronan the Accuser was told by Korath the Pursuer that the orb was taken by a Ravager and Yondu's adoptive son, a thief who went by the name "Star-Lord" Her actions led her to be under arrest by Nova Corps. When they were at the Kyln, Peter Quill saved her life from a group of criminals who wanted to kill her. She informed Star-Lord and Rocket Raccoon about her four million units deal with the Collector. They swore to split it into four ways. They were able to escape on the Kyln. During their time on Knowhere, Gamora tells Peter of her life with Thanos and Quill tells her about his life on Earth.

Throughout the film, Gamora and Quill grow close with one another. During the battle of Xandar, Gamora yelled for Peter to take her hand while he was being ripped apart. Her, along with the rest of the Guardians came in to their defense and they defeated Ronan the Accuser once and for all.

Gamora tries to persuade Peter to not give Udonta the stone, but unknown to her and Yondu, Peter switched the orbs and gave his foster father the one containing the troll toy. When Udonta leaves, Peter shows her that he indeed switched them out and kept the real orb, much to Gamora's ammusment. She points out that Yondu was going to kill him, but Peter tells her that he was the only known family that he ever had. However, Gamora tells him that Yondu is not the only family he's got. The team later grieves for the loss of Groot while others celebrate.

Gamora was with Peter when he learned that he was half-human and half-alien, which presents with her saying that's why he held the power stone as long as he did.

Later abourd their ship, Gamora notices Peter listening to Ain't No Mountain High Enough and begins moving a little bit to the beat. Gamora states they will follow his lead, and calls him by his alias. Peter claims they'll do "a bit of both."

Guardians of the Galaxy Vol. 2
Gamora and the other Guardians make a deal with the Sovereign to kill the Abilisk to take back custody of her adoptive sister Nebula after what she had done on Xander. Gamora's mission to punish Nebula was delayed when she and the other Guardians come into contact with Ego, the long lost father of Star-lord. While Ego said he wanted to have some bonding time with his son, Gamora and the other Guardians (except for Peter) become suspicious about Ego. After showing his true self, Gamora and the other Guardians team up to defeat him, But at the cost of Yondu Udonta sacrificing himself, the Guardians held a funereal for Yondu in honor of his life. Gamora then started a relationship with Star-lord.

Avengers: Infinity War
The Guardians of the Galaxy responded to the distress call sent out by the Statesman after the Asgardian ship was attacked by Thanos and his Black Order. Gamora was concerned with helping people in distress, while Rocket Raccoon and Star-Lord were interested in how much they could get as a reward. Upon arrival at the origin of the distress call, they found the Statesman destroyed and recovered Thor from the wreckage.

Gamora was taken with Thor's physique, much to the discomfort of Star-Lord who began imitating the Asgardian king. Thor recounted his encounter with Thanos to the Guardians, telling them that the Mad Titan was after the Infinity Stones. With two in his possession, and two safely on Earth, Thor surmised that Thanos was heading to Knowhere to get the Reality Stone, which was in the possession of the Collector. Thor also mentioned that no one knew where the Soul Stone was, to which Gamora reacted uncomfortably. Thor, along with Rocket and Groot, headed to Nidavellir to forge a weapon to kill Thanos with, while Gamora accompanied Star-Lord, Drax the Destroyer, and Mantis to Knowhere.On the way to Knowhere, Gamora took Star-Lord to one side and made him promise to kill her if Thanos captured her. Gamora told him that she knew something that Thanos could never know. Star-Lord asked her what it was, but Gamora refused to tell him, stating that he would be in danger if he knew as well. As they embraced each other their moment was interrupted by Drax the Destroyer, who was "mastering" the art of being invisible by standing totally still.

Arriving at Knowhere, the Guardians of the Galaxy then headed to the Collector's Museum to find Thanos threatening the Collector and demanding to know where the Reality Stone was. Sensing an opportunity, Gamora attacked Thanos, stabbing him in the neck with Godslayer and then plunging the dagger that he gave her into his chest. As Thanos died, Gamora broke down crying. As she did, Thanos' voice rang out, telling her that he was sure she still cared about him.Thanos had already obtained the Reality Stone, and had staged the entire event. The Reality Stone revealed the true nature of Knowhere; burning and destroyed with Thanos alive and well. Taking Gamora hostage, the Guardians attempted to save her, but Thanos used the Reality Stone to temporarily take out Drax and Mantis. Star-Lord aimed his Quad Blasters at Thanos, threatening to kill him if he did not let Gamora go.

Gamora reminded Star-Lord of his promise and he reluctantly pointed the weapon at her with Thanos tempting him to shoot her. After confessing their love for each other, Star-Lord finally worked up the courage and resolve to shoot Gamora, but Thanos used the Reality Stone to turn the weapon's discharge into bubbles. Telling Star-Lord he liked him, Thanos used the Space Stone to transport away from Knowhere.

Gamora was brought to Thanos' throne room as he tried to reconnect with his lost daughter but she rebuffed his offer of food, throwing the food he offered to his throne, which she bitterly said she always hated. Thanos recalled that she had told him that for twenty years, but he had hoped that one day Gamora would have sat in the throne after him.

Gamora reminisces on how she was young when Thanos took her and rebuffed his belief that he saved her, saying that she was happy in Zen-Whoberi, which Thanos countered by saying on how her planet was so overpopulated that children had no homes and to survive, her people had to hound the planet for scraps and he was the one who saved her planet. Gamora bitterly said that he did it by wiping out half of the Zehobereis and Thanos simply said that it is a small price to pay for salvation. As the talk became more tense, with Gamora rejecting all that Thanos believed and expressing her hatred for him and everything he taught her, Thanos told Gamora that it was because of what he taught her that she became the fiercest woman in the galaxy and he trusted her enough to find the Soul Stone; Gamora sarcastically apologized for failing him. Thanos calmly told her that he was disappointed in her not because she failed him, but because she had found the Soul Stone and lied to him about it.

Thanos took Gamora to see Nebula, who he captured after she snuck aboard the Sanctuary II, suspended in a field with her cybernetic body parts pulled apart. Thanos tortured her in front of Gamora to make her reveal the location of the Soul Stone. After telling Thanos that she did not know its location, Thanos accessed Nebula's memory and had Nebula play it back via a hologram projection from her eye showing Gamora telling her sister that she had found the map to the Soul Stone and burned it, with Thanos revealing he had never been fooled by Gamora's lie and was simply waiting for the right moment to expose it. Torturing Nebula some more, Gamora finally relented and told Thanos the Stone was on the planet Vormir.

Gamora, giving in after watching Nebula being tortured, reluctantly led Thanos to a planet called Vormir, which is where they meet the Red Skull who guided them to the obtaining the Soul Stone. Red Skull explained to Thanos that he needed a sacrifice of a loved one to be given the Infinity Stone, by throwing that person off the cliff to their death.

Gamora, upon hearing this, unleashed her bitter resentment for Thanos' seeming lack of love for anyone by laughing and saying how she had dreamed that Thanos would be punished for all he had done, and that the moment is finally there as the universe found Thanos unworthy, because he loved no one but himself. Thanos turned around and revealed tears, which she believed was due to his failure and continued to taunt him. Unfortunately, Thanos was crying because he would have to sacrifice Gamora as he truly loved Gamora as his daughter. Genuinely surprised and for a brief moment, almost happy, Gamora still quickly attempted suicide to prevent Thanos obtaining the stone, but Thanos easily turned her dagger to bubbles and tearfully apologized and, while still in tears, dragged her over to the cliff and threw her to her death. Thanos then awakened with the Soul Stone in his hand.

After Thanos snapped his fingers with the Infinity Gauntlet, he was transported to the Soulworld inside the Soul Stone. There, Gamora's soul met Thanos and calmly asked if he had done it and the resigned Thanos told her he had achieved his goal. Gamora asked what did it cost and Thanos sadly smiled and said it cost him everything, referring to how she was the only thing he loved. Apparently accepting defeat, Gamora sadly smiled before Thanos returned to reality.

Following her sacrifice on Vormir, Gamora's soul was transported into the Soul Stone, where she reverted to a child form similar to when she'd first met Thanos. After he successfully wiped out half of the universe's population, Thanos' consciousness briefly traveled into the Soulworld, where he faced his adoptive daughter. Gamora, turning to meet her adoptive father, asked if he completed his mission, to which he agreed. When she asked what it had cost him, the Mad Titan solemnly remarked that it cost everything he had.
