Who Is the Main Villain in Avatar 4?

The main villain in Avatar 4 is not definitively confirmed in public sources as of the latest coverage, but available reporting and early reviews indicate the film continues the franchise trend of human antagonists working through military or corporate interests while introducing antagonistic Na’vi factions and individual conspirators who pose the primary threat to Jake Sully’s family and allies[1].

Context and evidence
– Recent reviews of the third film in the series, released before Avatar 4, describe a recurring pattern in James Cameron’s films where human military or corporate figures act as central antagonists and where new internal Na’vi adversaries emerge; critics note a rebooted human villain archetype (the Stephen Lang figure) aligning with a pyro-priestess and hostile Na’vi factions, suggesting Avatar 4 is likely to continue featuring a mix of human and Na’vi antagonists rather than a single, wholly new type of villain[1].
– Trade and review coverage so far focuses on character dynamics—threats from humans seeking to colonize or exploit Pandora and from Na’vi groups who oppose Jake Sully’s clan—so the “main villain” may be framed as a coalition or a central human leader supported by local antagonists rather than a solitary mastermind[1].

What to watch for when identifying the main villain once the film is widely released
– Which character directs the largest, sustained threat to the protagonists across the story arc (a single person, a military/corporate organization, or a Na’vi faction).
– Narrative focus: whether the screenplay humanizes the antagonist or presents them as a systematic force (for example, corporate policy or military command) versus an individual leader whose motives and actions drive the plot.
– Marketing materials, official cast lists, and full reviews after release that name the antagonist explicitly.
