When choosing cosplay, it should be someone you would enjoy doing.
Definantly.
A big fuzzy guy with long hair, eh?
Well, get the hair done at a salon or something, or grab a wig, and cosplay Mr. Satan from DBZ.
He was a pretty big guy, and if you do your hair properly you should be easily able to do it.
I wouldn't be positive unless I saw your picture, but its all I could come up with, with the information you provided.
