There is no Dana, only Zuuuul!
Dana possessed by Zuul; Ghostbusters

Zuul (also known as The Gatekeeper) is a demigod and minion of Gozer, alongside Vinz Clortho. She[3] possessed Dana Barrett in Ghostbusters and both Callie Spengler and Lucky Domingo in Ghostbusters: Afterlife.


Zuul in the Primary Canon is developed from Ghostbusters (1984) and Ghostbusters: Afterlife. Zuul (prime) appear in the IDW Comic Series, a Secondary Canon, which follows Ghostbusters (1984) and also includes Tobin's Spirit Guide (Insight Editions).


Primary Canon History[]

Before Ghostbusters[]

Zuul, a minion of the god known as Gozer, was worshiped as a demigod by the Sumerians, Mesopotamians and Hittites in 6000 BC.[4][5][6] It was believed the souls of the dead were ruled by Gozer and protected by a powerful Gatekeeper and Keymaster but in order for Gozer to rise up and walk the human plane again, Gatekeeper and Keymaster had to assume the form of beasts.[7][8] Zuul was one of the entities recorded in Tobin's Spirit Guide, including illustrations of her Terror Dog form.

Ghostbusters (1984)[]

In 1984, when Dana opened her refrigerator to discover the inside was another dimension, she saw Gozer's temple. Zuul looked from the stairs and the other Terror Dog Vinz Clortho suddenly popped up and shouted, "Zuul" at Dana, only for her to freak out and run away screaming, slamming the fridge shut. Sometime later after the incident, during an intense thunderstorm one Thursday night, Zuul manifested in the physical plane atop the Shandor Building's rooftop, breaking out of a Gothic statue in its likeness. Zuul possessed Dana after she arrived home to get ready for her date with Peter Venkman. Demonic claws pinned Dana to her chair then telekinetic activity sent the chair to the kitchen, where Zuul waited to possess Dana.

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.

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.

Ghostbusters: Afterlife[]

One evening in summer 2021, Egon Spengler captured Vinz Clortho in a Trap and sped away from the Shandor Mining Company property in a company truck. He crashed through a locked chain link fence and drove through Summerville. Zuul took on an invisible form and pursued Egon. On the road to the Farmhouse, Zuul rammed the side of the truck. The truck flipped several times into a barley field and came to a stop upside down. Egon hobbled out of the field with the Trap and made it to the Farmhouse. He threw a lever on a column upwards on the porch and three capacitors nearby surged on. Zuul, still invisible, stepped out onto the field. Egon held out the Trap. Zuul took several steps forward. Egon stepped on a trap pedal but the capacitors died out. He tried again several times but nothing happened. He ran into the house and dug a P.K.E. Meter out of a drawer. It detected Zuul and he heard it prowling around. The lights flickered off. Egon hid the Trap in a secret space in the floor of the study and sat down on an armchair. Zuul manifested in a smoke-like form and crept up behind him. A vague Terror Dog form manifested in the smoke. Egon pressed a button and the P.K.E. Meter arms rose up into a taser setting. Several arm manifestations burst out of the chair and grabbed Egon. Zuul yowled and shot out of the house in the form of a pink P.K.E. wisp.

Two days after the release of Vinz by Phoebe Spengler, Podcast and Gary Grooberson, Zuul chose Callie Spengler as her human host to begin the ritual needed to summon Gozer again. Zuul entered Egon's underground laboratory in its mist-like Sentinel form. Callie failed to notice Zuul because she just learned Egon kept track of her entire life. Zuul mades its presence known with a snarl. Callie turned her head. From the darkness, Zuul lunged and roared at her then possessed her. Zuul, now in possession of Callie, returned to the Farmhouse and sat down on the armchair in the study. Phoebe, Podcast, Trevor and Lucky arrived at the Farmhouse after they explored the Shandor mine. Phoebe was the first to find Zuul but was unaware of the possession at first. Phoebe kept calling out to Callie but Zuul, without looking at her, replied, "There is no Mom, only Zuul". Phoebe and Podcast exchanged looks and slowly stepped toward who they thought was Callie. Phoebe asked her if she was okay. They saw Callie's eyes were red. Zuul repeated, "There is no Mom. There is only Zuul." Zuul's demonic voice came through then she started to breathe quickly. Trevor and Lucky ran in. Trevor wanted to know what was happening. Phoebe called to Callie again. Lucky asked if she was okay. The P.K.E. Meter registered an entity. Phoebe and Podcast leaned in. Podcast got on his knees in front of her. Zuul got in his face and snarled then stroked the left side of his face. She then asked Podcast if he was the Keymaster. Podcast had no idea. Phoebe was aghast. Podcast asked Phoebe what to do. Phoebe pulled at Zuul. Zuul snarled angrily. Trevor picked up the P.K.E. Meter, inexplicably in the study, too, but it suddenly went into taser mode. Zuul recognized the taser and quickly hid behind the chair and snarled.

Another earthquake was triggered across town. As Vinz disabled the contraption Egon had built inside the Temple of Gozer, Zuul took notice of the psychokinetic disturbance developing above the mine and leaped through the window then ran through the fields towards the Shandor Mine in search of Vinz. Once she arrived at the mining company property, Zuul soon found Vinz. She tore Callie's clothing off, materializing a golden dress in its place. Vinz complimented Zuul's eyes. Zuul spoke in dog gibberish. He thanked her, took the flower off his ear and offered it to her. She ate it. They embraced and kissed lustfully. After consummating the ritual, Zuul and Vinz entered the mine and took their places in the Temple of Gozer. Lightning from the crossrip struck them and they transformed into their Terror Dog forms. They awaited Gozer's return in the temple.

Gozer emerged from the sacrificial death pit, dispensed Ivo Shandor, greeted Zuul and Vinz, and it took its throne. The Terror Dogs hopped back down to their places. Phoebe stepped out from her hiding place to distract Gozer while Podcast remote-controlled the Remote Trap Vehicle underneath Zuul. It bumped Zuul's rear foot and Podcast narrowly avoided Zuul's detection. On the second try, Podcast got it dead center under Zuul. He triggered the Trap and Zuul was captured. The Terror Dog form dissipated, Callie was freed, and Gozer's power was split as it was not able to maintain its form without both Zuul and Vinz. With the Remote Trap Vehcile following Ecto-1 and Callie secured, Phoebe, Podcast and Trevor drove away from the Mine towards the Farmhouse in order to lure Gozer there. Vinz attacked Ecto-1 in Summerville and attempted to retrieve the Trap containing Zuul, but was ultimately unsuccessful.

After returning to the Farmhouse, Phoebe stood near the porch and held the Trap containing Zuul out to lure Gozer into the Trap Field. The trap failed, however, and Gozer used Lucky's Proton Stream to pull her away from the others. Vinz cut Lucky off from Phoebe and Callie, and Gozer seized the Trap. Gozer broke it open and freed Zuul. Zuul possessed Lucky and transformed again into her Terror Dog form. Zuul's restoration also allowed Gozer to reform. After Peter, Ray and Winston arrived, Peter taunted Gozer. Vinz attempted to charge forward, only to be stopped by Gozer. Zuul and Vinz could only watch on as the Ghostbusters, aided by Phoebe and the ghost of Egon, caught Gozer in a Proton Stream, and Trevor powered the Trap Field with the gunner seat's Proton Pack. With the Traps charged, Callie triggered them. Every entity on and around the property was captured, including Zuul. Zuul's body became a black husk. Lucky pushed one of her hands out and Trevor broke her out.

Secondary Canon History[]

IDW Comic Series[]

1000 years ago, give or take, as a protracted civil war between the Autobots and Decepticons came to an end on Cybertron when the former left the planet. The Decepticons were unable to pursue them due to the presence of Gozer, Zuul, and Vinz Clortho. Megatron, Shockwave, Soundwave, and Starscream approached the Temple of Gozer.

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.

Ghostbusters: Afterlife ScARe[]

Zuul appeared in a video message for the recruit, having possessed Lucky. Stating that Gozer was coming, Zuul said to wait for the sign and once "the prisoners" would be released, humanity would perish in flame. After releasing Lucky, Zuul let out a roar.

Zuul eventually engaged the recruit during their battle with Vinz Clortho, sneaking up on them with its invisibility before ambushing them. After being partially defeated, Zuul retreated through a portal and allowed Clortho to deal with them. Reappearing after Clortho was trapped, Zuul resumed its fight with the recruit before eventually being trapped.

Zuul was eventually freed from the Containment Unit by Gozer. However, it was recaptured by the recruit using the Trap Field.


Zuul is a large, horned, dog-like beast with blazing eyes known as a Terror Dog.

Ghostbusters (1984) Trivia[]

  • Zuul was originally a generic term for the other-dimensional creature that would later evolve into the Terror Dogs.[11]
  • 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.[12]
  • The Terror Dog stone statue paw that breaks was made with a soft carve-able foam covered with a thin layer of plaster.[13]
  • 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.[14]
  • 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.[15][16]
  • 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.[17]
  • 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.[18]
  • 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.[19]
  • Ivan Reitman provided all of the unearthly voices, such as Dana's demonic Zuul voice and Slimer, except for Gozer's.[20][21]

Ghostbusters: Afterlife Trivia[]

  • The billowing smoke was a practical effect using dry ice.[22]
  • Zuul attacks Egon in a similar way she attacked Dana Barrett in the first movie with multiple arms popping out of the chair.

  • Zuul leaves the Farmhouse in the form of a pink energy wisp like when the ghosts are released from the Containment Unit in the first movie.
  • Phoebe finds a small statue of Zuul's sentinel form on the desk in Egon's study when she first enters the Farmhouse.
  • The teenagers looking down the Shandor mine shaft and seeing a figure say "Gozer" mirrors the first movie when Dana Barrett looked in her refrigerator and sees a Terror Dog say "Zuul".
  • Possessed Callie's line "There is no Mom, only Zuul" is a callback to the first movie, Chapter 19: Peter's Date with Zuul, when she possessed Dana Barrett and told Peter, "There is no Dana, only Zuul."
    • The line was Jason Reitman's idea.[24]
  • Possessed Callie breathes heavily just like possessed Dana did in bed when the containment grid was shut down in the first movie, Chapter 21: Out of Biz.
  • When Zuul finds Vinz, he is lying down in a pose mirroring one Zuul did in the first movie, Chapter 25: Working the Crowd.
  • It is revealed Zuul materializes a shiny dress from her host's clothing, the dress being a callback to a similar outfit possessed Dana wore in the first movie, Chapter 19: Peter's Date with Zuul and for the rest of the movie.

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."

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.

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."

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."

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."
