The Real GhostbustersEdit
In the long term, storing captured entities in on-site containment vessels in the basement of the Firehouse would be both expensive and hazardous. Egon Spengler and Ray Stantz developed the Dimensionometer as a method to banish spirits to other dimensions permanently.  A test subject was sent through and the Dimensionometer proved a success.
However, a 20/40/60 news crew was present. Ever skeptical, Sandy Van Sanders caused an overload. In the chaos, Egon's soul was sucked into the Netherworld and a Possessor Demon stole Egon's body. After Winston Zeddemore and Peter Venkman hosed down the Dimensionometer with fire extinguishers, Peter went in to rescue Egon's soul while Janine held the fort. Ultimately Egon was returned to normal and the demon was sent back. The Dimensionometer wasn't too lucky and appeared to be scrapped.
