UltraPets
On the first day of school at Galaxy High, each student is assigned a pet-robot that serves as an aide and companion to them. Although they’re cute, if provoked the Ultrapets can transform into a powerful fighting machine and, in the blink of an eye, can immobilize an alien foe upon its master’s orders.
Fluffy: Josh's ultrapet, a cute robotic dog (actually a weasel but behaves like a dog) which helps the students throughout their missions. He is capable of transforming into a bipedal attack mode.
Spike: Spike is Toby's ultrapet.
