Jake Sully (born August 24, 2126)  is the main protagonist of Avatar. He is a paralyzed renegade Marine veteran who defects to the Na'vi race and is also one of the 20 known avatar drivers. He is the sixth Toruk Makto and Olo'eyktan of the Omaticaya clan.
After his twin brother, Tom, was killed on Earth, Jake agreed to replace him in the Avatar Program on Pandora, in which humans remotely control human/Na'vi hybrids to safely navigate the planet. He was originally assigned to gather intel that would help Colonel Quaritch find a way to force the Na'vi to leave Hometree, or destroy it if necessary. The Na'vi occupation of Hometree was blocking the RDA's access to a very large deposit of unobtanium underneath the tree. After spending time with the Na'vi, Jake abandons his original mission and stops reporting to Quaritch. Jake learns the ways of the Na'vi hunters from Neytiri and falls in love with her. He is eventually accepted into the Omaticaya clan and becomes Neytiri's mate. He turns against the RDA and, after becoming the sixth Toruk Makto, leads the Na'vi in a battle to drive the RDA off Pandora.
