A Zombie is a corpse brought back to life, usually by supernatural forces.
The Real GhostbustersEdit
The Petersons are Zombies that appear rose up from their former lands now owned by Samantha Stantz.  Egon Spengler, while donning Ecto Goggles, notes the Petersons leave behind an odd form of Ectoplasm.
Zombies also appear at Buster's party. Buster doesn't like Zombies because they have terrible teeth, which is due to their bodies having decayed during their time as lifeless corpses.  During the party, they were playing instruments and dancing. One was beating on the Containment Unit like it was a drum.
Though Zombies were not encountered by the Extreme Ghostbusters, Eduardo sees an illusion of himself as a Zombie  and the Vathek known as Crainiac, Corpuscle, and Gristle look a lot like Zombies. 
The Ultimate InvasionEdit
Zombies appear as regular enemies in the video game Extreme Ghostbusters: The Ultimate Invasion.
Ghostbusters: The Video GameEdit
Ghostbusters: The Video Game features a regular enemy known as the Grave Fiend, which is very much like a Zombie. It is referred to as a zombie in its Tobin's Spirit Guide entry's Contact Protocol section and is given the descriptor "Reanimator" in its classification.
- It should be noted that while Zombies are usually corporeal entities, the Zombies that appeared in The Real Ghostbusters appear as being something like a ghost.
