I am starting to make a G1 Galvatron Costume that actually transforms since my transforming Grimlock costume didnt go as planned. I was thinking of using a medium sized barrel shaped cardboard box for the torso, but I'm unsure on the legs. Since it needs an accurate altmode and Galvatron has quite skiny legs that are not as 'boxey' as someone such as Optimus or Megatron, I have gathered that I could use thick grey pants and add whatever details needed. I think this would allow a compact altmode, but it might make the torso box seem big. I would probably use a small-medium sized poster cardboard tube for the particle cannon, whihc as we all know, goes into the neck in altmode. Is there any suggestions for the costume as I am a huge Galvatron fan and want this to be as accurate as possible. And for the legs, I might add some type of cardboard to the bakc fo the legs to make it more, 'Galvatroney' in appearance. I will upload pictures as soon as I start the design etc. LEt me know your ideas and thoguhts and wish me luck!
