Zuul the Gatekeeper of Gozer is a demigod and minion of Gozer, The Destructor, alongside Vinz Clortho the Keymaster. Zuul is assumed to be female due to being known as The Gatekeeper and for possessing a female host instead of a male host. It possessed Dana Barrett in Ghostbusters. It was worshiped by the Mesopotamians, Sumerians and Hittites in 6000 BC, along with Gozer.   
In 1984, Zuul first appeared at Dana Barrett's apartment as she returned home with groceries. Zuul appeared inside her refrigerator, the contents of which were replaced by another dimension inhabited by the Temple of Gozer. Zuul growled out its name when Dana noticed it, causing her to scream in horror and seek the Ghostbusters for help days later. Weeks later during an intense thunderstorm, Zuul manifested in the physical plane atop the Shandor Building's rooftop, breaking out of a Gothic statue in its likeness. Zuul possessed Dana, as she arrived home to get ready for her date with Peter Venkman, by having demonic claws pin her to her armchair while it telekinetically propelled the chair into the kitchen where Zuul awaited her.
Zuul, now in possession of Dana Barrett, acted like a seductive temptress and sought only Vinz Clortho, who had likewise possessed Louis Tully, Dana's nerdy neighbor who harbored a not so secret crush on her. As Peter arrived for his date with Dana he noticed her radical change, but curiosity overpowered him and he proceeded to gain entrance to her apartment by tricking Zuul into believing he was a friend of The Keymaster. Peter asked her for her name and she introduced herself as Zuul "The Gatekeeper". Upon further prodding by Peter, Zuul revealed they must prepare for the coming of Gozer "The Destructor". Zuul then aggressively attempted to seduce Peter, to which he responded by refusing her advances, and insisting on talking to "Dana". Zuul was initially amused but became frustrated after further insisting. She responded in a horrific, demonic voice that, "There is no Dana, only Zuul!" Angered by Peter's persistence, Zuul (in Dana's body) began to levitate above her bed while growling and roaring ferociously at Peter. Later, Peter sedated Dana's possessed body with a large dose of thorazine.When Walter Peck shut down the storage facility, releasing all of the ghosts Zuul awoke, sensing the supernatural energy. She walked toward her living room, with a sinister grin, to get a closer look at the ghosts escaping from the Ghostbusters' headquarters. Upon seeing the supernatural energy fly in front of her building she suddenly blew out the wall of her apartment with a ferocious roar, leaving Vinz Clortho a way to locate her. Afterwards, The Keymaster noticed Dana's destroyed living room wall as he wandered along the street below. Shocked, he walked into the building and burst open her door. Vinz introduced himself as "The Keymaster" to which a grinning Zuul replied she was "The Gatekeeper". The two demons walked toward each other, meeting at the center of the demolished living room in a passionate embrace. They kissed lustfully before Zuul led Vinz toward an ominous mythical staircase leading up to the building rooftop as lightning flashed violently.
The two demonic beings finally consummated their union atop a stone table in front of the large temple atop the Shandor Building, the climax of which was implied when there was a tremendous earthquake, ripping apart both the buildings and the streets below. After the tremor, Zuul lay on her back on the stone table with her head resting on Vinz' crotch. She sat up, glancing around the rooftop temple as Vinz awoke shortly afterwards with a big, exhausted grin on his face and his torn belt buckle dangling between his legs. The seductive Zuul slid off the stone table, followed by Vinz. They walked down the table steps, staring in a trance at the lightning crashing atop the temple crown before Zuul slowly made her way towards one of the two opposite pedestals once occupied by the Terror Dogs as Vinz walked towards the other one.As the Ghostbusters made their way through Dana's apartment both Zuul and Vinz, now standing in the opposite pedestals once occupied by their Gothic statues, raised their arms to the sky, slowly. Suddenly they were both struck by bolts of lightning which they redirected towards the large temple doors, causing them to open. Once the doors were completely opened, Zuul began to absorb the supernatural lightning bolts, shaking violently and smiling as the Ghostbusters finally arrived and stared at her and Vinz. Having absorbed enough demonic energy, Zuul began to lower her arms down to the pedestal surface, her body thrashing uncontrollably under the force of the lightning shooting through her. As her hands touched the pedestal, a large lightning blast converged on her, transforming her and Vinz from Dana Barrett and Louis Tully's human forms back into their natural, satanic Terror Dog forms. The two beasts turned and roared menacingly at the Ghostbusters before taking their positions beside the crystalline temple doors which revealed Gozer. After the Ghostbusters crossed the streams and defeated Gozer, the full protonic reversal also affected Zuul and Vinz, turning their beastly bodies back to stone, leaving Dana Barrett and Louis Tully trapped inside their respective shells. The Ghostbusters dug them out and they survived, having no recollection of any of their actions while under demonic possession.
Secondary Canon HistoryEdit
The Real GhostbustersEdit
Zuul, along with her master and partner, left a great impact on the Ghostbusters' life. Their actions would leave a legacy with such ghosts as the Spectral Ghostbusters and the new Stay Puft Marshmallow Man. A Terror Dog also made a cameo appearance along with Samhain and a number of other ghosts on the second opening theme song of the Real Ghostbusters animated series and appeared in a few episodes.
Zuul appeared at Gozer's side when he induced telepathic contact with Ray during the Tiamat incident. Over a year after the Rowan North incident, the team learned about Gozer, Zuul, and Vinz Clortho from the original team after their dimensions accidentally overlapped from an accident with the Interspatial Teleportation Unit. Patty remembered the name "Zuul" and asked if that meant her team would one day fight Gozer. Kylie Griffin believed if Gozer manifested in their dimension, it would only be an echo.

Zuul is a demigod and loyal minion to the Sumerian shape-shifting god of destruction, Gozer the Gozerian. Zuul, known as the Gatekeeper, and Vinz Clortho the Keymaster are harbingers of destruction and primary agents for summoning Gozer.
Zuul appears as a corporeal Terror Dog, which is a large, powerful demonic monster with two horms and glowing red eyes. Zuul is able to possess a human being as a vessel in order to complete the ritual needed to secure Gozer's arrival.
Zuul is a large, horned, dog-like beast with blazing red eyes known as a Terror Dog.
In Ghostbusters: The Board Game, Zuul is a Class 6.
- Zuul was originally a generic term for the other-dimensional creature that would later evolve into the Terror Dogs. 
- In a deleted scene in the June 6 (and July 6), 1983 drafts, Zuul felt sorry for a horse in a bridle and harness and kissed it. 
- In the scene where Zuul grabs Dana, the bulging door effect was executed by stretching a thick sheet of latex rubber over a special door frame and makeshift handles attached to irregularly-shaped pieces of foam pushed against the elastic door. 
- Originally, the three arms that grab Dana were different - one human, one hook, and one green frog-like sucker arm. Ivan Reitman thought the sucker arm was too cartoonish and it was discarded.  
- The three arms were worn as glove appliances by three puppeteers who positioned themselves beneath Dana's arm chair or simply out of camera range. 
- The hairy arm from the chair scene was made with yak hair. It was punched in the arm with a filed down sewing needle that resembled a harpoon with a wood dowel handle. A silicone oil was used to lubricate the needle. 
- For the one shot of Zuul in Dana's kitchen, an articulated Terror Dog was finished later in production around the last days of shooting. As a result, the trashed set was completely rebuilt by John DeCuir and his crew for the one shot to be filmed. 
- Ivan Reitman provided all of the unearthly voices, such as Dana's demonic Zuul voice and Slimer, except for Gozer's.  
- Zuul is referenced in Ghostbusters: The Video Game (Realistic Versions) in an audio recording found during the Museum of (Super)Natural History Level. 
- The Temple of Gozer level pitch for Ghostbusters: The Video Game would have involved an appearance by Zuul. 
- Zuul is referenced in What in Samhain Just Happened?! on page eight. Janine's Car's license plate reads "GBI ZUL."
- Also in What in Samhain Just Happened?!, a guest of Artie Lester's party is dressed like Dana in Zuul's garb after she is saved by the Ghostbusters.
- Zuul is referenced in Ghostbusters Volume 2 Issue #2 on a poster in a foot locker on page 5.
- On Cover RI of Ghostbusters Volume 2 Issue #10, Zuul appears as part of a recreation of the "Then Die!" scene in the first movie.
- Zuul was added as a Kickstarter exclusive character to Cryptozotic Entertainment's Ghostbusters: The Board Game after the $350,000 stretch goal was achieved. She can only be acquired by backing the game during its fundraising period. The fundraising period ends March 11, 2015. 
- In the Ghostbusters: Mass Hysteria hard cover collection, on page three, the calculator is left on four digits to spell out 'Zuul.'
- On February 11, 2015, the 2nd stretch goal of Ghostbusters: The Board Game, $350,000, was introduced: Zuul. Zuul was the first to be limited to only Paranormal and Mass Hysteria backers.  Zuul was later unlocked and the 3rd stretch goal, $400,000, was introduced: Vinz Clortho. 
- On Zuul's character card in Ghostbusters: The Board Game
- The caption on the photograph quotes Peter's "So, she's a dog" line from the first movie when the Ghostbusters see Dana and Louis transformed into Terror Dogs.

Paragraph reads: "In Dan Aykroyd's original script, the root of New York's widespread psychic disturbances lay in the fact that a 'Zuul' -- a generic term for the other-dimensional creature which would later evolve into the Terror Dogs -- had somehow strayed out of its rightful time and place and was being held captive by the Ghostbusters' employer, himself a transdimensional being. Unfortunately, the Zuul happened to be a favored pet of the all-powerful Gozer -- absolute ruler of the sixth dimension -- who, it seemed, would stop at nothing to recover it. When this concept was superseded in subsequent drafts, Zuul became a given name for the female Terror Dog, which -- along with her like companion Vinz Clortho -- is seeking refuge from the Gozer in New York."
- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 124 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Paragraph reads: "The exchange between Louis and the horse harkens back to a deleted scene from the June and July drafts in which Venkman and the alien Zuul -- masquerading as human in Dana's body -- leave the restaurant and encounter several carriage horses. Noticing the bridles and harnesses, Zuul inquires if they are prisoners. Uncertain of her reaction, Venkman responds promptly: "No, no. They're volunteers. This is considered a good job for a horse." "They look so sad," Zuul laments, and then kisses one of the beasts with enough genuine emotion to elicit a worried look from the carriage driver. In the June draft, Venkman pulls her away and segues -- ever so smoothly -- into an invitation which leads to his surprise wakeup the next morning: "You know, I was just thinking. No trip to this dimension would be complete without a visit to the Times Square Motor Hotel."
- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 111 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Paragraph reads: "During production, it was decided to augment the eerie light effect by having the door actually bulge outward, as though some unearthly force was trying to push through it. To achieve the effect, Chuck Gaspar and his crew constructed a special door frame over which they stretched a thick sheet of latex rubber. Makeshift handles were then attached to irregularly-shaped pieces of foam -- early tests for the standing mounds of melted marshmallow required later in the film -- thereby allowing the lumpy foam shapes to be pushed against the elastic door from behind to create the desired indentations."
- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 112 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Paragraph reads: "Through the final three drafts of the script consistently described Dana's chairborne assault by two pairs of inhuman hands, it was decided from a practical point of view to limit the total number of hands to two. Curiously, the sequence ended up with three."
- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 112 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Michael Gross says: "It was always the intention to have only two, but when Thom Enriquez storyboarded the sequence, he showed the movement of one of the arms by drawing it in two positions, with cartoon-style movement lines in between. This drawing was misunderstood by the guys in the 'monster shop,' so they built three -- and since they had, we used them. When it came time to shoot the scene, Ivan decided to have the third arm come right up between Sigourney's legs. It really made the sequence much more terrifying and threatening. Originally, each arm was different. One was a human arm, one had a hook on the end of it and one was a green, frog-like sucker arm. Ivan didn't like the sucker arm -- he thought it looked too cartoonish -- so we ended up with two human arms and the one with the hook."

- ↑ Craig Caton-Largent deviantArt "Ghostbusters hairwork" 7/7/13 Paragraph reads: "Hair work for one of the arms that comes out of a chair and grabs Sigourney Weaver in Ghostbusters. Yak hair was used and hand punched in with a filed down sewing needle that resembled a harpoon that can sorta be seen in the top of the picture with a wood dowel handle. The little jar with the red top contained silicone oil that was used to lubricate the needle."
- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 112 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Michael Gross says: "Articulated puppets take a long time to build -- and we knew the articulated Terror Dog wouldn't be ready until our last couple days of shooting. So all of the shots requiring an articulated dog, such as the one in Dana's kitchen, had to wait until the very end. Unfortunately, by that time, Dana's apartment set had been completely trashed for later scenes in the film -- holes knocked in the walls and floors torn up and that sort of thing. So after everything else was done, John DeCuir and his crew had to go in and put that set completely back together -- for one Terror Dog shot."
