I have to say, the dreads. I love the idea of these three robots who are in a sense triplets, but are badass henchmen of Megatron. The designs for the three are so creepy in bot mode, but "serious business" in vehicle mode, they pull it off better than the Arcees. Personally, I would have called them Reflector. By the way, where was it confirmed that the dreads are called Crankcase? What do you think?
