Zuul and Vinz Clortho
Background
Zuul "the gatekeeper" and Vinz Clortho "the key master" are demigods worshiped by the Hittites, Mesopotamians and Sumerians around 6,000 BC. They are the minions of Gozer.
During the events of Ghostbusters (1984)
Dana Barrett hears a growling noise from her fridge and opens it up and a large dog like creature says Zuul. Later, Dana goes into her apartment and as she sits down, she is grabbed by demonic arms that come out of the couch and she is pulled towards the fridge and an incarnation of Zuul as the dog statue. At Louis Tully's party, Ted Fleming and Annette Fleming arrive at the party and after Louise throws their coats into the closet, Vinz Clortho manifested as the dog statue breaks out of the closet and chases him. Louise runs out of his apartment and takes the elevator as Louis's Neighbor sees Vin Clortho and runs back inside her apartment. Louis runs out of the building and runs to the Tavern on the Green and is attacked by Vin Clortho. Louis, now possessed, looks for the gatekeeper and after talking to a horse and being interrupted by Coachman, yells at the Coachman that he will perish in flames. Dana and Louis are transformed into the dog like forms of Zuul and Vinz Clortho. Gozer walks out from a sky temple/portal and Dr. Raymond Stantz approaches it and asks it to return to its own realm. Gozer asks if Raymond is a god, and when Raymond responds in the negative, Gozer tries to kills the Ghostbusters. The Ghostbusters turn on their proton weapons and fire at Gozer, but she easily jumps away. They fire at her again and she disappears. Gozer's voice calls out that Volguus Zildrohar the Traveler has come and they must choose their form of the destructor. Raymond imagines the image of the Stay Puft Marshmallow Man and a giant Stay Puft Marshmallow Man appears and starts to destroy the city. The Ghostbusters fire their weapons at it and catches it on fire, but continues to walk towards them. Dr. Egon Spengler suggests to cross the streams and fire them at the dimensional portal and after they do, the portal disappears and the Stay Puft Marshamallow Man explodes, covering everyone in marshmallow. Dr. Peter Venkman initially thinks Dana is dead, but discovers the dog form was only a shell and they free her and Louis.
