Transformers These dolls are artist hand-cast by Batchix and were part of the development process that eventually led to the Gamma and Epsilon boys. The red and white one is Sideswipe and the yellow and black one is Sunstreaker, from Transformers. Both dolls have magnetic 'wings' that look like doors. I had to recast, with permission, the right arm of Sideswipe in order to replace a missing arm from Sunstreaker.
