All good points and posts. I love being a character and the costume just enhances that part of me. When the helmet is off, I'm Jim, but when I'm in costume, it's TK-8455 (or whatever costume I have on). I don't act silly, just sort of "play the part" as much as possible. I think we all have used the word "citizen" from time-to-time and that plays into the role. The biggest question I am asked is "where did you get that costume"? My response is always, "Lord Vader and/or the Empire". If the helmet is off, then I get more personal and talk to folks that are interested in the Legion, armor, and/or costuming in general.
