The Nether Entities are various creatures that reside in the dimension ruled by Gorgar.
When the Ghostbusters arrived in another dimension, the first type of Nether Entity they encountered were flying Batwinged Eyeballs.  After they returned back to New York City, the Ghostbusters accidentally caused it to transform into part of Gorgar's dimension. Several Nether Entities came through portals and began terrorizing people and eating vehicles. Due to the physics of the dimension, the Proton Packs were useless against the entities. Ray Stantz reversed the effects by sending Gorgar back to his dimension with the Magic Cabinet. As a result, everything was sent back including the Nether Entities.
