Big Brain

Big Brain is a minor antagonist in the remake of The Hills Have Eyes.

Biography
Big Brain is an apparent authority figure of Jupiter's clan, as he is shown issuing commands to other mutants on multiple occasions through a walkie-talkie. Big Brain apparently suffers from a large distended head and bloated throat. Due to his physical condition, Big Brain is unable to walk and is confined to a wheelchair.

Attack on the Carters
Early in the film, Big Brain's voice is heard over Goggle's walkie-talkie, ordering another mutant to kill the rest of the Carters.

Big Brain is fully seen when Doug finds him in an electronics-filled house in the Hill People's nuclear test village home. While interrogating Big Brain on his daughter's whereabouts, Doug learns about the family's origins; when he threatens Big Brain with a baseball bat, Big Brain summons an axe-wielding Pluto, sparking an intense fight between to two.

Near the end of the fight, Doug is apparently weakened and begs Pluto for his life, which ends up being a distraction for him, as, when Big Brain starts mocking Doug's begging and Pluto has his head turned, Doug swiftly attacks and kills Pluto, but, concerned for his baby, cannot spare the time to kill Big Brain. Big Brain then commands Lizard to kill Catherine on his walkie talkie, before he is mauled to death by Beast.
