I couldn't take it anymore, I had to fix his head. I carefully cut off the old antennae from Orion and an extra Faith Leader anime head that I had lying around. Then performed the delicate transplant. The head has to come off for transformation, but I don't really care since I never put it in alt mode.
Definitely an improvement! Stock head on this guy seemed so bland. With his larger eartenna he can hear the hush of a dying star.
