We see two new Na'vi tribes in the trailer: the Wind Traders and the Ash People clan, the latter of whom seem to represent most of the menace in the film. We see the Ash People using fire as a weapon, with one of the aliens even seeming to be able to wield it on her bare hands without hurting herself.

Neytiri (Zoe Saldaña) and family go on a new adventure and discover a new enemy in James Cameron's "Avatar: Fire and Ash."
