Radster

&nbsp

Radster confronted the Rangers once Brunt retreated and then he himself retreated when the Rangers released the Galactabeasts. He later came back with Furio to Terra Venture and was destroyed by the Lion Galactabeast.

In "The Sunflower Search," Radster was featured in a flashback as part of Scorpius' attack upon the Magna Defender's planet 3,000 years ago.
