|This article is about a/an monster in Power Rangers Lost Galaxy.|
Radster was called in to confront the Galaxy Rangers when Brunt failed to maintain his capture of the Galactabeasts on the wild planet. Radster himself was eventually forced to retreat when the Rangers released the Galactabeasts. He returned with Furio to Terra Venture, fighting off Commander Stanton's squad of GSA soldiers who put up a minor resistance against the two monsters before the Power Rangers arrived. He later was destroyed by the Lion Galactabeast. Radster is a lobster and/or scorpion-themed monster. In the first battle with the Ranger he wields a spear, on Terra Venture he wields a pistol in battle.
Radster was among the monsters in the Shadow World.
