What role does the mangkwan clan play in the new avatar film?

In Avatar: Fire and Ash, the Mangkwan clan is introduced as a hostile Na'vi faction that poses a significant threat to the Sully family and the broader Na'vi community on Pandora. The film positions the Mangkwan as a rival group to Jake Sully's clan, characterized as ruthless and antagonistic. Their role is explicitly tied to the central conflict of the story, where they clash with the human-turned-Na'vi Jake Sully and his family, who are already engaged in a struggle against the human RDA forces. The evidence does not elaborate on the Mangkwan's specific motivations, internal dynamics, or leadership beyond their characterization as a hostile clan, but their inclusion expands the narrative's scope by introducing a native Na'vi adversary that complicates the established alliances and conflicts on Pandora. This dual threat of human and Na'vi opposition underscores the film's focus on internal and external conflicts within the Na'vi society.
