Vinz Clortho; Ghostbusters

Sloars (alternately spelled Slor) are rather large reptilian beasts not from this world. Gozer was noted for taking the form of a giant one by Vinz Clortho in the first movie. The first appearance of a Sloar takes place in Ghostbusters: The Video Game (Realistic Versions).


Sloars in the Primary Canon is developed from Ghostbusters (1984). In Ghostbusters: The Video Game (Realistic Versions), a Secondary Canon, Ghostbusters (1984) and Ghostbusters II pre-date the game, Ghostbusters: Afterlife conflicts with the game. Sloars appears in the IDW Comic Series, a Secondary Canon, which follows Ghostbusters (1984) and Ghostbusters II, also includes some elements from Ghostbusters: The Video Game (Realistic Versions) and Ghostbusters: The Video Game (Stylized Versions); as well as being canon to Tobin's Spirit Guide (Insight Editions).


Primary Canon History

Before Modern Times

Gozer took the form of a giant Sloar during the Third Reconciliation of the Last of the Meketrex Supplicants. According to Vinz Clortho, "Many Shubs and Zulls knew what it was to roast in the depths of a Sloar that day I can tell you."

Secondary Canon History

Ghostbusters: The Video Game

In the early 20th century, the Cult of Gozer, under Ivo Shandor's guidance, lured a Juvenile Sloar from its hell dimension and imprisoned it in a ghost world pocket at the heart of Shandor Island. It was forced to guard the Cult's Orrery. Its overwhelming rage at being imprisoned within Shandor Island allowed it to produce massive amounts of Black Slime, which Shandor later refined into the common forms of Psychomagnotheric Slime. These were then pumped into the sewers of New York City, forming a River of Slime. During the Shandor Incident of 1991 while inside Shandor Island, the team dispatched the Juvenile Sloar shortly after deactivating the Mandala inside the castle.

Insight Editions

Sloars were giant creatures with no eyes. They were essentially a living furnace. Its innards slowly burned whatever it consumed.[1]

IDW Comics

Towards the end of the battle between Gozer and Tiamat in Ray Stantz's mind, Gozer took the form of a Sloar and emerged from the Stay Puft Marshmallow Man. Tiamat was not amused by Gozer's choice. Once Gozer realized he couldn't open the Containment Unit by conventional means, Tiamat reached into the Sloar and ripped Gozer's consciousness out.


Ghostbusters (1984) Trivia

Ghostbusters: The Video Game Trivia

  • On page 57 of the October 8, 2007 third draft of Ghostbusters: The Video Game's revised cut-scene script, a Butler Ghost is the final boss of Lost Island Rising instead of a Sloar.[2]
  • According to Drew Haworth, Creative Director on Ghostbusters: The Video Game, there was some debate about whether using a Sloar or a Torb.[3]
  • Part of the Checking Out the Library Level was at one point planned to take place on the back of a Sloar as it was flying.[4]
  • Due to time constraints during production of the game, the design of the Sloar was given a humanoid physique so it would easier to integrate.[5]
  • After defeating the Sloar, Ray asks if it had multiple eyes. While this would technically be true in the realistic version because of the eyes the creature creates during the first phase of the boss fight; it would also be correct if the player fought the Black Slime Behemoth in the stylized version, as the Black Slime Behemoth has eyes all over his body.
  • In the New York City Public Library, during the second encounter with Crusto and Cruster, a display shows a panel about Wolf Van Shandor. Van Shandor's art samples are actually recycled rejected designs of the Sloar.[Note 1]

  4. skankerzero post Ghostbusters Fans 7/20/15 skankerzero says: "One of the original Sloar ideas was for it to be a giant 'living level'. The idea was that the library (I believe) was on the Sloar's back as it was flying. There are some concepts for this idea, but it was shelved as we wouldn't have had time to get it working properly.""
  5. skankerzero post Ghostbusters Fans 7/20/15 skankerzero says: "The idea of what a Sloar actually was was very vague. It was just a throwaway sentence in part 2 I believe, so we had a lot of freedom to do what we wanted with it. Honestly, I was not a fan of the final approved concept. It could have been a much more creative design but we were strapped for time so certain design elements had to be there in order to make it as easy to integrate as possible. (Mainly the humanoid physique)""
