Chuck's Reviews Transformers Combiner Wars Hot Spot and Groove
 

Wrapping up our look at Wave 3 of Combiner Wars, Hot Spot and Groove round out the Protectobots. Hot Spot is a great update of the character with a slick modern Firetruck design. Transformation to torso mode is quite enjoyable, and as fun as Silverbolt. Groove unfortunately suffers from a compact motorcycle mode that transforms to an overly thin robot mode. The chest plate is nice, and holds better than Blackjack, but not something I'd use often.
