The Fish Market Haunter is a grotesque fish-like ghost that hates tuna.
A little after 10 pm, the Ghostbusters were called to a fish market to deal with a troublesome ghost. While the caller tried to explain the situation, the ghost hit Peter Venkman over the head with a tuna. The ghost hid in a marlin on display but was soon found by the guys. It proved rather agile and dodged the Proton Streams. A possessed Ray Stantz let the haunter go and lied his equipment was jammed.
- Oddly, the ghost hates fish. 
- On page 16 of Ghostbusters International #10, in panel 2, behind Jenny Moran is a bag of Fish & Chips bearing an image of Fish Market Haunter.
