Sylphon was one of the ghosts captured by Spooks Away and stored in the Prediction Engine. After the Ghostbusters destabilized the Mega-Entity by luring Slimer out with doughnuts, Slyphon was seen flying away with a Gremlin riding it.
It appears to be a caterpillar with fish and dolphin traits. His name is based on the mytho of Sylph.
- Sylphon appears on the Regular Cover of Ghostbusters 35th Anniversary: Extreme Ghostbusters.
