Gozer the Gozerian also known as Gozer the Destructor, Volguus Zildorohar and The Traveler is the name of a fictional Sumerian god who is the major supernatural enemy in the film, Ghostbusters. The character may have been an in-joke being one of the Hebrew names for a surgeon who performs circumcisions.

He is assisted by two dog-like minions called Zuul (The Gatekeeper) and Vinz Clortho (The Keymaster). Gozer the Traveller appears in one of his pre-chosen forms. During the rectification of the Valdranaii the Traveller came as a very large and moving Torr. In the third reconciliation of the last of the Meketrex supplicants they chose a new form for him, that of a giant Slorr. Many Shubs and Zuuls knew what it was to be roasted in the depths of the Slorr that day, I'll tell you.

After World War I, an insane surgeon called Ivo Shandor , a leader of an secret apocalyptic cult, designed a massive apartment building in New York City specifically to gather psychic energy that would power a portal that would allow Gozer and his minions to enter the world and destroy it.

By 1984, the building had gathered enough energy to pull the minions through with plans of possessing suitable humans to open the portal on top of the building to allow Gozer through. If one supposed that a Twinkie represents the normal amount of psychokinetic energy in the New York area, based on Dr. Spengler's reading, the energy gathered in 1984 would be a Twinkie thirty-five feet long, weighing approximately six hundred pounds. As a byproduct, numerous ghosts were revived and became active throughout the city as they waited to join their new master.

Unfortunately for them, an unforseen development occurred that created a powerful opposition to Gozer. Three unemployed parapsychology professors had coincidentally formed a business called Ghostbusters, a specteral investigation and removal service armed with technology of their own design that could track down and capture the entities with unprecedented ease. Unaware of the cause of this sudden spike of paranormal activity, the company had brisk business capturing numerous ghosts to the point where they were concerned about the capacity of their containment grid.

When an overzealous EPA inspector, Walter Peck, ordered the grid deactivated against the advice of the Ghostbusters, a massive break out of the ghosts occurred which caused widespread haunting that immediately sparked chaos throughout the city. The Ghostbusters managed to convince the authorities to let them deal with the crisis and they confronted Gozer as he emerged from the portal on top of Shandor's building.

After an initial skirmish, Gozer demanded that Ghostbusters choose the form which the Destructor would take. Ray Stanz reflexively choose an innocuous corporate mascot, the Stay Puft Marshmallow Man. The result was the bizarre sight of a giant marshmallow man in a sailor suit with an insane smile stomping through New York toward the building. The Ghostbusters eventually stopped the god by crossing their proton pack streams as they fired at the portal. This created total protonic reversal which caused an explosion that apparently closed the portal and destroyed or at least neutralized Gozer and his minions and returned the possessed humans back to normal.
