Back in my day, you had to manually convert your Transformer toys from vehicle / beast / boombox shape to bipedal robot form. The Beijing-based SenPower wants to take all the fun away with these self-transforming toys.

I had no luck tracking down availability or pricing, just in case you like playing with your Transformers without having to deal with the arduous task of transforming them. It's sufficient to say if you want one, you're going to have to wait.
