Gozer The Gozerian, also known as "The Destructor", "The Destroyer", "Volguus Zildrohar", "Lord of The Sebouillia", "Scourge of the Glethestements" and "The Traveler." An eldritch abomination of unknown origin, Gozer is a sadistic, shapeshifting, apocalyptic, cosmic entity (worshipped as a god by the Hittite, Mesopotamian and Sumerian cultures) who appears as the first film's main antagonist.
In Ghostbusters terminology from West End Games' role-playing game, Gozer would be a Class 7 Metaspectre. Gozer never appeared in The Real Ghostbusters animated series and it never gave a classification for it (the 1984 film did not classify Gozer either, apart from indicating it was a god). However, Gozer is referred to several times and described by Ray Stantz as a "Primal God" in the episode, "Janine Melnitz, Ghostbuster". Gozer was also used as a benchmark for other potent entities encountered, such as Proteus, Nexxa, Murray The Mantis and Great Cthulhu.
Gozer itself is reputed to be the most powerful being the Ghostbusters have ever faced. It displayed an extraordinary array of abilities including dimensional travel, shape-changing, telepathy, great agility and stamina, energy attacks (casting lightning bolts), invisibility, intangibility, pyrokinesis, teleportation and weather control. In fact, its mere entering and presence within Earth's dimension caused increases in paranormal activity and the disruption of natural forces (the storm clouds and earthquakes before/during the battle with the Ghostbusters). Gozer proved so powerful, that the Ghostbusters had to resort to crossing the streams, using Total Protonic Reversal to destroy the portal and hurl Gozer and its minions back their own universe.
As briefly mentioned in the film and fully covered by the 2009 game sequel, cults worshipping Gozer and its minions arose around 6000 BC before being banished by the Babylonian goddess Tiamat following a protracted conflict between their followers. Via its chief minions – Terror Dogs Zuul the Gatekeeper and Vinz Clortho the Keymaster, Gozer can escape to other realities. Upon entering a given dimension – as a profane form of granting a last request, Gozer demands of those who witness its arrival to "CHOOSE THE FORM OF THE DESTRUCTOR", a physical avatar it will manifest as to destroy that plane of existence.
In the 1920s, cult leader Ivo Shandor and his followers set Gozer's Coming in motion, eventually happening as the "Manhattan Crossrip of 1984", when Its minions Zuul and Vinz Clortho opened the portal for it to emerge from the rooftop temple of 550 Central Park West (55 Central Park West). Though initially appearing in the form of an androgynous humanoid woman, Gozer uses Ray's accidental thought to assume its Destructor form of the Stay Puft Marshmallow Man before later being banished back to its hellish realm.
Gozer "reappears" in the 2009 game via the Gozerian Mandala-revived form of Mr. Stay Puft. Without a portal to Gozer's domain, it is comparatively weaker than from its initial manifestation. Ray realizes that Gozer made a critical mistake of taking the form of a marshmallow man; it is forever trapped in this form whenever reentering the mortal realm and thus unable of taking forms of more effective avatars. In addition, the Ghostbusters have been upgrading their arsenal since their first encounter which includes "boson darts", in which the Stay-Puff is very vulnerable of. The Ghostbusters are able to defeat Gozer again and this time not needing to resort of crossing their proton streams. Later in the story, a disillusioned Ivo Shandor (possessing the mayor of New York) confronted the Ghostbusters. He produced the skull of Gozer's female humanoid avatar, angrily renounced his faith in The Traveler and contemptuously discarded it. Yet even with this second defeat, this is merely another setback for Gozer and waiting for another opportunity to unleash its wrath.
Gozer is best known for its phrases and quotes such as "Are you a god?" (Ray: "No...") "Then... DIE!!!" (blasts the Ghostbusters with lightning) or its disembodied voice saying "THE TRAVELER HAS COME!" and "CHOOSE AND PERISH!" Gozer was played by Yugoslav actress/model Slavitza Jovan and its demonic voice was provided by Paddi Edwards.
