Brain Suckers have only been spotted at Disposal Plant P-12A, aka the "Dead Factory". They behave in a very similar fashion to Drain Deimos, but they are slightly stronger and capable of spitting poisonous fluids at enemies. The exoskeletons of these deformed creatures are torn in various places, exposing patches of muscle beneath. Most notable is the fact that Brain Suckers each have two heads, each one with two long wirey tongues. These monsters are called "Brain Suckers" because their prefered nourishment appears to be the brains of their victims.
