Avatar: Fire and Ash is set to introduce a new clan of Na'vi to James Cameron's franchise, and new reports from the film seem to suggest that it may also be replacing its main character.Everything known about Fire and Ash suggests that the film will follow up on the events of Avatar: The Way of Water with Jake Sully and his family, but will also reveal a new, darker side of the Na'vi. This fresh skew now seems to be setting up for a new lead to take over the story in its subsequent installments.
