Appear in: The Brood (1979)
Scariest moment: In the middle of an otherwise calm grade school classroom, two of the evil kids beat their teacher to death with toy hammers.
Weakness: The death of their mother, Nola Carveth (Samantha Egger), kills them, due to the loss of her psychic connection.

If there was ever an effective tool to dissuade men from treating women poorly, it's David Cronenberg's excellent 1979 horror freak show The Brood. Enraged by her son-of-a-bitch husband's (Art Hindle) abusive ways, Nola Carveth (Samantha Eggar) literally embodies her anger, numerous times, in the form of inhuman, bloodthirsty, asexual kids without navels.

Telepathically engineered to kill, Nola's devilish brood helped Cronenberg's film to redefine the overused horror term "creepy kid movie," and, subsequently, set a standard that's yet to be outdone.
