Wretches appear as large, humanoid creatures with the head, and thus, the nature and mannerisms, of a large pig. They have leather straps around different parts of their body and limbs, similar to the Servant Grunt. A loincloth of some sort is also visible on their persona. It is interesting to note that while their arms are like those of a human being, their legs are more like those of an actual pig in terms of jointage. Even so, they still have the bare feet of a normal human. They also have some sort of steel collar around their neck, as well as a leather hood over their head. Their eyes glow green and they sometimes move on all fours, usually to move faster. Like other ManPigs, their left arm is shorter.
Upon spawning, Wretches will scout around the map in search of the game's protagonist, Oswald. Upon spotting him, they will stand up, stagger a bit, and let out a threatening, blood curdling squeal, before charging after him. They cannot be killed and must be ran and hidden from. They move at fast speeds, and it can be hard to avoid them sometimes, as they can see just fine, even in the dark. They aren't very tough, however, as it takes five hits for them to kill Oswald. This doesn't mean you shouldn't worry, however, as around the third or fourth hit, Oswald becomes slower and easier to kill. If Oswald is out of their reach, they will wander off somewhere else. They appear visually very often, and are seen at least twice feeding on human flesh. They usually appear in twos and will stop at nothing to please the Machine, whom they worship as a god. They also seem to be the lowest class in the ManPig community, as one is seen getting shoved over by an Engineer, and another is later killed by a Tesla.
