The Cthulhu Cult Leader (possibly named Jim McElroy) is a minor villain from South Park. He is first seen buying lemon bars off of the kids in their superhero personae. He tells them that their efforts to stop Cthulhu are futile, and compliments them on the lemon bars.
The cult leader later shows up in an alley after Mysterion (revealed to be Kenny) asks the goth kids about a passage in the Necronomicon. One of the goth kids brandishes a switchblade, and the leader instructs him to kill Kenny with it. He does not want to, so the leader takes the knife and stabs Kenny himself.
He is not seen again after this, nor is it mentioned what happened to him.
The cult leader appears to be a man in his early to mid 40's. He has a large nose and usually has a strange, almost unsettling smile on his face.
He wears a collarless dark blue button-up shirt under a brownish gray jacket, yellow pants with a black belt, and black shoes.
His hair is shaved on the sides and back, but longer at the top, giving it an appearance similar to that of a bowl cut. It is parted in the middle.
When conducting cult meetings, the leader wears a black hooded robe with a white anarchy symbol on the left breast. The hood of the robe covers half of his face.
- It is mentioned that the Cthulhu cult meetings are held at somebody named Jim McElroy's house. It is possible that this is the cult leader's actual name, though it is never mentioned if the cult leader actually lives in the house the meeting is being held in or if he is just one of many guests at somebody else's house.
