The Blood Eel from Iron Lung is an enormous, deep-sea aquatic horror inhabiting a blood-filled ocean. It is described as a mutated, amalgamated creature, with designs featuring merged human skulls for a face, protruding vein-like gills, and a tail composed of, or shaped by, human remains. The creature is nearly blind, relying on sensing vibrations in the ocean, and is often portrayed as an uncomfortably large, toothy, and incomprehensible entity that barely fits within the claustrophobic confines of the game's setting.
