A Class 5 Entity (that is part of the Classification System) is a mid-level specter that takes on a non-humanoid form. The most well-known of which is Slimer, the Full Roaming Vapor who haunted the 12th floor of the Sedgewick Hotel in New York, New York.


Class 5 Entities are ectoplasmic manifestations of definable but non-human looking creatures with some form of intelligence. Speculation includes theories that Class 5's are:

  • Former human remnant ghosts which have 'devolved' or 'mutated' into other forms as they slowly lost their memories of their former selves
  • Ghostly entities from another dimension that entered our world through interdimensional portals
  • Simply born out of ecto-energy into whatever form they wear now
  • A side effect from ritual summoning
  • Byproducts formed from emotionally-charged events such as murder and suicide

Taken from Ghostbusters Role-Playing GameEdit

Class V: These are ectoplasmic manifestations of definite but non-human form. Speculation includes the theory that Class V's are formed from emotionally-charged events or as side effects from ritual summonings. (The spud Peter Venkman talks about so much was a by-product of the rituals that a cult held in the Sedgewick basement.) These typically require extensive Proton Pack implementation to eradicate.

List of Spirits/Ghosts based on The RPG GuidelinesEdit

Taken from Ghostbusters: The Video Game (Stylized Version)Edit

Via Tobin's Spirit Guide: SlimerEdit

I have seen vaporous manifestations with vaguely humanoid faces, but grotesquely distorted bodies and spindly, nigh-useless appendages. I believe these malformed entities are manifestations of raw psychic energy, and could represent some of the primal vices like gluttony or rage. They don't seem to be bound to any physical restrictions and since they have no specific tie to a human spirit it eludes me as to how one would deal with such a manifestation.

Animated Series Class 5Edit

The animated series doesn't follow the same rules as RPG and can go higher. To read more about it go to Animated Classifications.
