I cannot live without a Rom - Spaceknight costume despite my poor construction skills. It's obscure enough that most people would just think I was a robot. The people I really care to impress are the ones who know who Rom was. I would need some outside help to wire the electronics so his eyes, Translator, and Neutralizer light up.
I don't think I have ever seen a Rom cosplayer in all the cosplay pictures I have seen. I am hooked up with some of the best convention photographers out there (Like American Comicon) and I know he would never pass on photographing even a crappy version of Rom if there was one in the hall.
