Jake Sully and Miles Quaritch

Miles Quaritch's personality is that of a brutal, ruthless, and loyal soldier, an antagonist who embodies colonialism, but with complex facets such as respect for his troops, admiration for the skill of his enemies, and a strong sense of revenge, showing moments of great charisma, sarcasm, and a reluctance to be completely evil, even adopting Na'vi customs in his recombinant form to understand the "enemy" and fulfill his mission.

Fierce Warrior: Expert in combat, with excellent aim and melee skills, relentless and aggressive.
Authoritarian Leader: Charismatic, funny, sometimes carefree and persuasive, he inspires respect in his soldiers, although he is aware of his limitations in protecting them all.

After serving in the United States Marine Corps with the 1st Reconnaissance Battalion, Quaritch became a senior officer in the security forces of the Resource Development Administration (RDA), a megacorporation, and was sent to Pandora's exomoon, where he served as its head of security. Leading the RDA in its conflict against the indigenous Na'vi, Quaritch enlists the help of newcomer Jake Sully to spy on the Na'vi and help him defeat them. Sully eventually activates the RDA and thwarts an attempt by an RDA force led by Quaritch to destroy the Tree of Souls. During the battle, Quaritch is killed by Neytiri. Afterward, the RDA transfers a copy of his consciousness into a genetically engineered Na'vi body, known as a Recombinant, which returns to Pandora to track down Sully along with other Recombinates. However, it is unsuccessful in this attempt but survives a second encounter with Sully.

Jake Sully served in the 1st Reconnaissance Battalion of the United States Marine Corps, but was discharged after an injury left him paralyzed from the waist down. After learning that his identical twin brother, Tom, has died, Jake agrees to replace him in the RDA's Avatar Program on Pandora, where humans remotely control human/Na'vi hybrids to safely navigate the planet. Lost in Pandora's forests, Jake is attacked by a pack of viperwolves when Neytiri, a Na'vi, saves him. Jake turns against the RDA after sympathizing with the Na'vi. Jake becomes the sixth Toruk Makto and leads the Na'vi in ​​a battle to expel the RDA from Pandora. After his human body is mortally wounded, Jake's consciousness is permanently transferred into his avatar through the Tree of Souls. When fighting, he only fights with a dagger, bare fists, or firearms; he refuses to fight with Na'vis weapons such as spears, bows, etc.
