They're called Choro Q Transformers. They both have wheels so in vehicle mode, you can pull them back and you could watch them go (yes, even Megatron). They were made around mid to late 90's and they're kinda hard to find. Only made three different kinds. Optimus Prime, Megatron, and Rodimus Prime. The place that I got these from were just clearing out stock, so I got them for 5 bucks each. I'm trying to locate Optimus, but I'm not willing to pay 20 bucks for it. h:
