Mama

Mama is a minor antagonist in Wes Craven's The Hills Have Eyes.

Biography
Mama is the partner/wife of Jupiter, with whom she birthed 4 children (3 sons and a daughter) and they have taken to living in the desert hills and killing any passerbys in the area, cannibalizing them afterwards. Like her husband, Mama is authoritarian with her children, often reprimanding and insulting her daughter for her reluctance to participate with the family's deeds.

Attacking the Carters
While Mama doesn't really do much during the attack on the Carter family, she does stay at the family's den, where she holds Ruby in place for trying to leave. Mama continually torments Ruby, even leaving her roped outside. Eventually, when Mars is told to kill the Carters' baby, Ruby knocks Mama out and runs off with the baby.

After that, Mama isn't seen again, although it might be possible she was apprehended or killed by authorities after the attack and deaths of most of her family.
