Vinz Clortho
Vinz Clortho, a male Terror Dog, was the Keymaster of Gozer. As a male, his horns were larger and more impressive than those of his female counterpart, Zuul the Gatekeeper. Vinz had a gargoyle crafted in his likeness on the rooftop of the Shandor Building, flanking a temple.
After "hatching" from their statues in modern times, the two Terror Dogs possessed two tenants in the building in order to copulate and thus open the gateway to Gozer's dimension. Vinz chose to possess Louis Tully. Vinz manifested his possession in Louis by flaring his eyes red and growling like an animal when upset. He successfully located and mated with fellow possessed tenant Dana Barrett, who was under the control of the demon Zuul, in a shrine atop their apartment buidling. After mating, the two demons opened the interdimensional portal for Gozer and transformed back to their natural monstruous forms once Gozer was freed to enter through the Temple, trapping Louis inside his demonic being along with Dana inside of Zuul's demonic body. Both beasts were destroyed when the Ghostbusters "crossed the streams" and reversed the particle flow through the gateway, creating a massive explosion. Louis was extracted, alive and unharmed, from Vinz's burnt corpse while Dana was extracted from Zuul's charred remains.
