Brain Jackers have no measurable intelligence. They resemble spiders, with a flabby abdominal cavity. Like rot worms, Brain Jackers survive by manipulating the dead. Clinging to the head of a dead creature, a Brain Jacker will stick its legs into the brain and tap into the dead creature's nervous system, thus enabling the Brain Jacker to control the body at will.
