Seek

His appearance: Seek is an entity consisting of an amorphous, black, slime-like substance with multiple eyes. It has no fixed shape, but can change forms at will. Its body and eye(s) emit a red light. For mobile players, Seek appears as a slimy humanoid figure, while console or PC players may see it with a red outline from certain angles. On low graphics settings, Seek is entirely black and does not emit any red or white light. During chase sequences, Seek starts as a small puddle and transforms into a featureless humanoid figure with a single eye. It also takes the appearance of long arms trying to grab the player in the final room.
