YOU’VE BEEN SLIMED!!!
Ectoplasm
Ectoplasm (also known as Ghost Slime and Ectoplasmic Residue) is a substance that comes from ghosts and outworldly beings. It usually appears in a form of a slimy green substance, but sometimes is visually completely absent, leaving only energetic traces Egon usually finds with his gear.
All ghosts and paranormal activities are considered to be “ectoplasmic” by Ghostbusters, leading to the conclusion that it is a scientific equivalent to the occult term “magic power”. It is speculated that it is the state of being which the outworldly creatures like ghosts and demons take in order to enter our realm.
Classification System
- Class 1
These are undeveloped forms, insubstantial and difficult to see. Interaction with their environment is limited and enigmatic (i.e., spectral lights, voices and sounds, ectoplasmic vapors, etc.). Simple application of a proton pack beam is normally effective.
- Class 2
Manifestations focused in this time and space, Class II ghosts and up can physically manipulate things in this world. These forms are vague, inconsistent, or incomplete (i.e., floating sheets, ghostly hands, animated lips, etc.). Although a proton pack beam is normally effective, some Class II ghosts have the capacity to return attacks.
- Class 3
Anonymous Hauntings. Distinct human form and personality is evident, but former identity (I.E., as a living being.) is not established. If established, ghost is reassigned as Class IV. Often difficult to deal with, Class III ghosts generally possess sophisticated means of defense.
- Class 4
Identity is established. They have a distinct human form and personality with known identity, such as General Custer or Cleopatra. Economic disposal methods include research into the background of said entity, as well as possible communication with it.
- Class 5
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 summoning (i.e. Slimer and Muncher.). These typically require extensive proton pack implementation to eradicate.
- Class 6
Ghosts from lower life forms. A giant penguin was once seen attacking a mugger in Central Park. Later, it was discovered that the penguin was a ghost. Unique solutions are often required to handle these entities, including research into habitats, allergies, natural enemies, etc.
- Class 7
Metaspectres. Obsessively malevolent, exceptionally powerful, and exhibiting control over subordinate forms, such entities are potentially very dangerous. These are often identified by primitive cultures as “Demons”. Entitles which fit this classification include Gozer and Zuul. Neutralizing them is usually a problematical undertaking at best. Most standard procedures are futile. The most realistic plan is to take measures to prevent these things from entering the sphere of influence in the first place.
