- ―Vinz Clortho[src]
Sloars (alternately spelled "Slor") are rather large beasts not from this world. Gozer was noted for taking the form of one by Vinz Clortho in the first movie. In Ghostbusters: The Video Game the first and (so far) only appearance of one happens.
Imprisoned Juvenile SloarEdit
The Juvenile Sloar is in Realistic versions of the video game instead of Black Slime Behemoth which was not included. For strategy on defeating him, go to Lost Island Rising Level (realistic version).
According to Tobin's Spirit GuideEdit
- Category: Class VII Ectoplasmic Outsider
- Type: Deity (supreme being)
- Attacks: Range
- Weaknesses: Slime
Somehow Shandor's cult, guided by Ivo himself, discovered a way to lure a young Sloar from its home hell dimension into our world. More impressively they also managed to imprison that Sloar within a ghost world pocket at the heart of Shandor's island mansion. Fueled by hatred, bile, and anger and assisted by mechanical monstrosities of Shandor's own design, this captive Sloar serves as the powerful guardian of the Lost Island's dimension-aligning Orrery machinery.
After you've finished gawking at the Sloar, equip your Slime Blower. The Sloar attacks in phases. During its first phase, he attacks by shooting lasers from floating eyes. Disperse the floating eyes with your Slime Blower to force the Sloar into Phase 2. During its second phase, it begins a two-pronged attack, switching between a head slam and projectile Black Slime. Stay on the move to dodge its attacks and keep a constant stream of slime on the Sloar's glowing forehead during Phase 2.
- Shandor's Island
A Sloar is something of which no one on earth knows what it is. Gozer took this form during the third reconciliation of the Vauldrani. According to Vinz Clortho, "Many Shubs and Zuuls knew what it was to roast in the depths of a Sloar that day I can tell you." One of the key words of Vinz Clortho's testimony was that Gozer took the form of a giant Sloar. Which would imply that while the Juvenile Sloar was huge, and that a typical adult Sloar would be much larger.
This implies that the internal body heat inside a Sloar can reach many hundreds of degrees, and somehow has a physiological property that enables victims to still stay alive to suffer the temperatures, at least for a brief time. Also, it is likely that a Sloar was a great fiery beast from the Shubs and the Zuuls mythology.
In Ghostbusters: The Video Game (the realistic version), while inside Shandor Island, the team has to dispatch a Juvenile Sloar shortly after destroying the Mandala inside the castle. 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 Mood Slime. These were then pumped into the sewers of New York City, thus making the Sloar the source of the River of Slime.
Secondary Canon HistoryEdit
Towards the end of the battle between Gozer and Tiamat in Ray Stantz' 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.
- There seems to be a conflict of spellings for Sloar, as Ghostbusters film subtitles and the novelization of Ghostbusters spells it Sloar, while the Ghostbusters: The Video Game (Realistic Versions) spells it Slor. It is most likely a simple oversight on the part of Atari.
- According to Drew Haworth, Creative Director on Ghostbusters: The Video Game, there was some debate about whether using a Sloar or a Torb. 
- 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. 
- 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. 
- 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 
- When the Imprisoned Juvenile Sloar first appears, Peter likens its smell to the Fulton Fish Market, an actual establishment in the Bronx.
- On page 10 of Ghostbusters Issue #4, Idulnas suggests a Sloar as a new Destructor Form for Gozer.
