Brunt was one of Scorpius' generals who kidnapped the Galactabeasts. But he was tricked by Maya, leaving them behind and Scorpius punished him for failing him. Brunt was never seen ever again.
Brunt is a recolored hybrid of two monsters from Beetleborgs, another show Saban made that was very similar to Power Rangers. He has the head of Mean Green Cannon Machine and the de-spiked body of Rocket Man.
