Jake Sully, or Tsyeyk te Suli in the Naʼvi language, is a fictional character and main protagonist of the American science fiction film series Avatar, created by James Cameron. Jake Sully served with the U.S. Marine Corps 1st Reconnaissance Battalion 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 the Pandoran woods, Jake is attacked by a group of viperwolves when Neytiri, a Na'vi, saves him. Jake turns against the RDA after sympathizing with the Na'vi and mating with Neytiri. Jake becomes the sixth Toruk Makto and leads the Na'vi in a battle to drive the RDA off Pandora. After the battle, Jake's consciousness is permanently transferred into his avatar via the Tree of Souls. Over the following fifteen years, Jake has three children with Neytiri: Neteyam, Lo'ak, and Tuk, and adopts two others: Kiri and Miles "Spider" Socorro.
