Animated Classifications

The Classifications or classes in the cartoon seem to vary from the film and Ghostbusters Role-Playing Game Classification System. The power of the entity seems to be the base of the scale, and the scale seems higher than the Role-Playing Game (RPG) version. Although, the classifications from the RPG do roughly scale upward in terms of power.

In the cartoon, the system ran on a Class 1 to Class 13 scale, with 13 being the strongest and least likely to see. Various books, such as "Tobin's Spirit Guide" and "Who's Who in the Spirit World," served as the basis for the Animated Classification system. [1] [2]


In The Real Ghostbusters episode "Ghosts R Us," the Ghostbusters encountered a Class 10 Toy Ghost that inhabited the abandoned toy factory chasing off the Class 7 Turlock. Class 10 ghosts and higher are considered extremely rare.

The Ghostbusters also encountered a Class 8 ghost called Mee-Krah (in episode "Standing Room Only."

In episode "Short Stuff" and "Revenge of the Ghostmaster," the Ghostbusters encountered an even rarer Class 11 ghost called The Ghostmaster.

In episode "Slimer Streak," they meet up with a ghost called "The Player" which is most widely presumed to be stronger than a Class 10 ghost; some believe it to be a new Class 12.

The Boogieman was identified as a Class 7 Corporeal Entity. Hob Anagarak was stated to be at least a Class 7, but could not be precisely measured due to a P.K.E. Meter overload (it is also possible his prison reduced his emanations).

The Player, Mee-Krah, the Ghostmaster, and the Master of Shadows are all much stronger than a Class 7 ghost.

In the Extreme Ghostbusters episode "The Unseen," the Ghostbusters encounter a Class 13 ghost named Tenebraug. Tenebraug is the strongest ghost by the scale, the Ghostbusters have encountered yet. It is unknown if there is a cap to the scale of the ghost classification system. However, entities such as Cathulhu were noted to be beyond the standard scale.

In Marvel Comics Annual 1990, they used a classification system similar to the one used in the Role-Playing Game, except a Class 6 entity was described as being close to a Class 7. Also, while the class system in the comic only goes up to Class 7 like in the movies, Ray mentions he is off to bust an unlisted Class 9 in the introduction.


Class 1Edit

Only one Class 1 was shown. It briefly appeared in an issue of the NOW comic book. [3] It was used to demonstrate the capabilities of Ecto-X. Class ones are non sentient manifestations and are almost completely harmless.

Class 2Edit

Class 2s are described as being very weak entities. The only true Class 2 encountered were the Pallo Mansion ghosts. Before their vacation at the Stantz Dairy Farm, the Ghostbusters encountered a Class 2 in the linguini of a client named Mrs. Fiorini. [4] Ray theorized The Petersons to be a Class 2 Area Aberration. [5]

Class 3Edit

Like Class 2, Class 3s are relatively weak.

Examples of Class 3's:

Class 4Edit

In the animated series, Class 4 describes a creature roughly similar to a Class 5.

Examples of Class 4's:

Class 5Edit

Much like Slimer, other Class 5 ghosts are vaguely humanoid in appearance and often slime things.

Examples of Class 5's:

Class 6Edit

Class 6 here classifies ghosts that are pretty powerful, but weaker than Class 7 spirits. However, some Class 6 entities are animal or animal-like ghosts.

Examples of Class 6's:

Class 7Edit

As in the movies, a Class 7 is a very powerful entity with godlike powers. Unlike in the movies, it is possible to trap and contain a Class 7.

Examples of Class 7's:

Class 8Edit

These ghosts tend to consider themselves superior over others and are usually demons. At a scale of power, they are slightly more powerful than Class 7 ghosts. Like Class 7 spirits, Class 8 entities can be captured in ghost traps.

Examples of Class 8's:

Class 9Edit

Class 9 spirits are even more powerful. They are so powerful that they are very difficult to trap, if it is possible to do so.

Examples of Class 9's:

Class 10Edit

Class 10 spectres are very powerful. The original Ghostbusters could only destroy the Class 10 they encountered, the Toy Ghost, with the self-destruction of Ecto-2.

Examples of Class 10's:

Class 11Edit

Class 11 ghosts are extremely powerful leaders of lesser ghosts. The only Class 11 spirit ever encountered by the Ghostbusters was the Ghostmaster. Ray originally thought it would be impossible for the traps to hold him, but one of them managed to after he expended too much of his personal power.

Class 12Edit

Though never actually seen, Class 12 phantoms are even stronger than Class 11 ghosts. The Player is often speculated by fans to be a Class 12.

Class 13Edit

A Class 13 is a new Class Level only used in Extreme Ghostbusters. The only known Class 13 entity was an eye-stealing demon named Tenebraug.

Unknown ClassesEdit

Since it is never stated exactly how many classes there are in the animated series, there may be even more Classes. There are also some ghosts on the show whose classes are not given, as well as ghosts whose power is beyond the standard class system.

Examples of Ghosts with Unknown Classes:

Examples of Ghosts beyond the standard Class System:


  • The first mention of a Class 9 was not in any of the animated series but in the novelization of the first Ghostbusters movie. In Ghostbusters: The Supernatural Spectacular, Peter Venkman purposefully released a Class 9 Autonomous Roaming Disrupter in the offices of The National Reporter because of articles that smeared the Ghostbusters as fakes and charlatans.
