Rocketron is a monster under the command of Barbarax. Aided by the Swabbies, he was sent to stop the Galaxy Rangers from leaving Captain Mutiny's planet and reporting the true nature of the Machine that would help the Terra Venture escape The Lost Galaxy. After the Rangers defeated his Swabbies, Rocketron engaged the Rangers himself. Finally, Leo summoned the Red Capsular Cycle and attacked Rocketron with Fireball Mode, shattering his body. Rocketron reformed and grew giant, causing the Rangers to summon the Galaxy Megazord. Rocketron was unable to defeat the Galaxy Megazord and activated his self-destruct, holding the Megazord to himself so that his self-destruct would destroy it as well. In response, Leo summons the Stratoforce Megazord which attacked Rocketron, forcing the monster to re
