Janine is the GhostbustersTM ' secretary. In the fire station, she normally works hard answering phone calls and accepting contracts. However, she is also an important member of the team and, in emergencies, will don her GhostbustersTM uniform and help fight the supernatural.
Louis Tully is an accountant and tax officer who lives in the same apartment complex as Dana Barrett. Later, he becomes the GhostbustersTM' lawyer, although he would rather be a real Ghostbuster. During an investigation at the fire station, Egon discovers (thanks to the special lab helmet), that Louis is possesed by a powerful ghost.
Egon is the brains of the GhostbustersTM team. He's an expert in techniques for studying ghosts. Most of the GhostbustersTM' gadgets, such as the proton pack and the ghost traps, were developed by Egon, together with Ray Stanz.
The Library Ghost is the first ghost the GhostbustersTM face. It's based on this encounter that the team develops most of their equipment.
The GhostbustersTM ' ghost traps release a strong energy field upon activation, creating a suction force, against which most ghosts stand no chance. In order to be sucked into the ghost traps, ghosts must first be incapacitated by the proton pack.
This machine is used for storing ghosts. By putting the trap inside and activating the lever, the ghosts are removed from the traps and locked up in the Storage Facility.
An important tool for the ghost hunt: a particle accelerator in the backpack of this device generates the energy rays that the GhostbustersTM use to incapacitate the ghosts. After that, they catch them in the ghost traps.
