Who's who in <em>Avatar: The Way of Water</em>

Formerly a paraplegic Marine, Jake Sully (Sam Worthington) was sent to Pandora in the first Avatar movie to replace his dead twin brother, who had signed up to meld his mind into the body of a Na'vi, the moon's blue-skinned indigenous species. After joining the Na'vi in a revolt against his fellow "sky people" in the first film, the sequel finds Jake as the chief of the Omaticaya, leading guerrilla attacks against the returned human invaders while also raising a family with his wife Neytiri, which includes his sons Neteyam and Lo'ak, his daughter Tuk, and adoptive daughter Kiri.
