Poso's Followers were a gang of ghosts that aided Boss Poso.
Much like their boss, Poso's Followers dress and act like 1930's era gangsters. They first appeared in a shopping mall and lured Janine Melnitz and Louis Tully into a trap by posting a sign for a big sale on the third floor. They were kidnapped upon entering an elevator. Two followers patrolled Ghost Town in anticipation of the Ghostbusters' rescue attempt and rounded up Peter Venkman. Three were sent to the Firehouse, as well. They were captured by Egon Spengler when he tricked them into standing in front of the Containment Unit's control panel. The rest left Ghost Town, New Jersey after Poso was captured and returned to their old haunts.
