Avatar: Fire & Ash Villains Teases An Exciting New Antagonist for Avatar 4 & 5
![]()
The villains in Avatar: The Way of Water were compelling and complex, especially Colonel Miles Quaritch (Stephen Lang) and Varang (Oona Chaplin). However, I’m really interested to find out more about the even larger threat hinted at for the fourth and fifth Avatar movies.
