So apperently there is or was a show in Japan called Hyper Rescue Drive Head. Where these kids pilot these robot suits that attach to cara and do giant robot stuff. I absolutely love the figures although I have never seen the show. The figures remind me of the headmaster Jr's from Transformers: Masterforce except instead of the smaller component being a humanoid that turns into the head, it's a full sized car the pilot sits in that changes into a head I expect. The cool thing is the cars are hot wheel sized and do roll freel although they are a bit cheap. The robots are mostly posable and only lack head articulation. The limbs are interchangeable and apparently there are different bits you can swap. It's also by Takara so pretty descent little toys overall.
