Gasser was dispatched by Furio to put the Terra Venture colony into a deep slumber with his distinct gasses. He turned the Galactabeasts into stone. He was destroyed by the Galaxy Megazord. He was later revived by Hexuba.
- Gasser and Sledger are brothers in the Gingaman version, while as despicted in Power Rangers, they're not. The first Megazord battle in Lost Galaxy against Gasser was cut short despite the fact that each episode has to run for 30 minutes (including commercials) so therefore, the extended Zord fight between the Galaxy Megazord against Gasser and Sledger has been cut.
