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 wandered around Central Park in search of the Gatekeeper before getting arrested and placed under the Ghostbusters custody. Vinz escaped once the firehouse exploded, releasing all of the captured ghosts onto the city. Amid the chaos, Vinz was finally able to successfully locate the Gatekeeper, whom had possessed Louis' fellow tenant, and longtime crush, Dana Barrett. The two demons shared a passionate kiss inside Dana's apartment before mating at the shrine atop their apartment building.
Afterwards, the possessed pair opened the interdimensional portal for Gozer and transformed back to the natural monstrous forms of their inhabitants 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.
