Hi everyone. I found this toy robot at an estate sale. Can someone please tell me what it is? It has the head of a stormtrooper but it also has these ridiculous wrench hands. There is a battery pack on the back which I think powers lights on the chest, but it isn't working. It is about 12" tall and the only markings are "made in Hong Kong" on the back. The cover from the battery pack is missing and may have more information on it. Unfortunately it is lost. Any comments would be appreciated. Thanks!
