Avatar: Fire and Ash (the third film) follows Jake Sully's family grieving Neteyam's death, as they clash with the aggressive, fire-wielding Ash People (Mangkwan) led by Varang, who align with the RDA's Colonel Quaritch, forcing the Sullys into a darker conflict involving volcanic lands, Neytiri's rage, and difficult choices about vengeance and family, while exploring themes of hatred, sacrifice, and the escalating war for Pandora.
