The Body Squeezers were a race of malevolent alien beings originating from an unknown planet that arrived on Earth with a meteorite. They are able to enter and possess human bodies by squeezing them. The Body Squeezers are described as big green-skinned beings with oval black eyes, deep nostrils and a small, lipless mouth. They also have two curled tusks and caps of green skin formed over their foreheads, curved and hard like a turtle shell. The destruction of their leader led to the destruction of the entire group residing on Earth.
