Jake Sully
Jake Sully was born in August 24, 2126 on Earth and spent his childhood hearing stories about Pandora, a fictional inhabited Earth-like moon in Alpha Centauri. Upon reaching adulthood, Jake became a Marine and during a service in Venezuela he suffered a serve spinal injury, leaving him paralyzed from the waist down. One night, during a bar brawl Jake was thrown out on the street and met the RDA agents, which told him that his twin brother, Ph.D. Tom Sully who previously trained as an avatar operator was murdered. They offered a opportunity to replace him because of their genetical identity, which Jake accepted and was sent for a trip to Pandora abroad the ISV Venture Star. When he arrives on Pandora, Dr. Grace Augustine, head of the Avatar Program, considers Sully an inadequate replacement but accepts his assignment as a bodyguard. While escorting the avatars of Grace and fellow scientist Dr. Norm Spellman, Jake's avatar is attacked by a thanator and flees into the forest, where he is rescued by Neytiri, a female Na'vi. Witnessing an auspicious sign, she takes him to her clan. Neytiri's mother Mo'at, the clan's spiritual leader, orders her daughter to initiate Jake into their society. Colonel Miles Quaritch, head of RDA's private security force, takes advantage of Jake's new position by promising Jake that in exchange for information about the Na'vi, the company will pay for an operation that would give Jake the ability to walk again. When Grace learns of this, she transfers herself, Jake, and Norm to an outpost. Over the following three months, Jake and Neytiri fall in love as Jake grows to sympathize with the natives. Jake reveals his change of allegiance when he attempts to disable a bulldozer that threatens to destroy a sacred Na'vi site. When Quaritch shows a video recording of Jake's attack on the bulldozer to Administrator Parker Selfridge, and another in which Jake admits that the Na'vi will never abandon Hometree, Selfridge orders Hometree destroyed. Jake then convinces Selfridge to give him one hour to convince the Na'vi to evacuate before commencing the attack. Jake confesses to the Na'vi that he was a spy, and they take him and Grace captive. Quaritch's men destroy Hometree. In the midst of the chaos, Mo'at frees Jake and Grace, but they are detached from their avatars and imprisoned by Quaritch's forces. Pilot Trudy Chacón, disgusted by Quaritch's brutality, frees Jake, Grace, and Norm, and airlifts them to Grace's outpost, but Grace is shot by Quaritch during the escape. To regain the Na'vi's trust, Jake connects his mind to that of Toruk, a dragon-like predator feared and honored by the Na'vi. Jake finds the refugees at the sacred Tree of Souls and pleads with Mo'at to heal Grace. The clan attempts to transfer Grace from her human body into her avatar with the aid of the Tree of Souls, but she dies before the process can be completed. Supported by the new chief Tsu'tey, Jake unites the clan and tells them to gather all of the clans to battle the RDA. During the subsequent battle, the Na'vi suffer heavy casualties, but are rescued when Pandoran wildlife unexpectedly join the attack and overwhelm the humans, which Neytiri interprets as Eywa's answer to Jake's prayer. Jake destroys a makeshift bomber before it can reach the Tree of Souls; Quaritch, wearing an AMP suit, escapes from his own damaged aircraft, then later finds and breaks open the avatar link unit containing Jake's human body, exposing it to Pandora's poisonous atmosphere. Quaritch prepares to slit the throat of Jake's avatar, but Neytiri kills Quaritch and saves Jake from suffocation, seeing his human form for the first time. With the exceptions of Jake, Norm and a select few others, all humans are expelled from Pandora and sent back to Earth. Jake is permanently transferred into his avatar with the aid of the Tree of Souls. Shortly after successful consciousness transfer, Jake's human body is given a traditional Na'vi burial and Jake moves the Omaticaya Clan near The Hell's Gate Facility to be close to the human allies who were allowed to stay on Pandora.
Two weeks later, Jake is over at his former body's burial site taking downtime and still envisioning himself as a human when Neytiri informs him she must go visit the Olangi Clan, due to them suffering the most casualties from the war and needing the most help. Jake agrees with her, thinking about how the other clan's belief in him is getting shaky despite having been Toruk Makto, and sees her off. Jake confides in Mo'at his lack of self-confidence as clan leader and the guilt he is still facing for Hometree's destruction, but Mo'at assures Jake he is stronger than he thinks, and that their new home and him becoming Olo'eyktan was Eywa's will. Artsut, the mother of Tsu'tey, becomes angry and argues with Mo'at just before her other son, Arvok, arrives with his father and challenges Jake's position as Olo'eyktan by invoking First Blood. Mo'at warns Jake that the ritual is dangerous, but Jake agrees to fight Arvok regardless. Jake easily defeats Arvok by cutting him on the arm and drawing blood. Arvok becomes angry about his loss and then throws his knife at Jake, who catches it, inadvertently being poisoned and collapsing into a coma. In his coma, Jake has nightmares where he is tormented by Miles Quaritch and the deceased Tsu'tey, until he unintentionally makes tsaheylu with the Tree of Souls and is transported into the Pandoran Neural Network. He is visited by the manifested spirits of Eytukan and Tsu'tey who urge him to forgive himself for his mistakes and offer guidance. Artsut and Ateyo's plan is revealed by Tsu'tey after which he explains to Jake that although their actions were wrong, they had the interests of the Omaticaya at heart; they needed to be punished for their wrongdoings, but Jake could be merciful towards them in doing so. When Jake wakes from his coma, he chooses to exile Artsut and Ateyo for attempt to assassinate him. After they leave, he promises the gathered Omaticaya that he'll do his best to lead them to a better future. Later Jake reunites with Neytiri, who comments that he doesn't seem like himself. He replies that on the contrary, he's never felt more like himself. James Cameron offered the role to Matt Damon, with a 10% stake in the film's profits, but Damon turned the film down because of his commitment to "The Bourne Ultimatum". Other notable actors who auditioned for the part include Chris Pratt and Chris Pine with the studio pushing Jake Gyllenhaal to play the role. Ultimately, the three finalists for the role were Channing Tatum, Chris Evans, and Sam Worthington, with Cameron ultimately going with Worthington based on his read of the climactic speech, saying: For his performance in "Avatar", Worthington won Best Actor at the 36th Saturn Awards.
