Mine is Newport squad leader Charles Brenten of Dominion Tank Police, one of my favorite animes from back in the day. As for a signature, I don't have one at the moment.
Gotta love Sforza's new signature.
I keep thinking that my sig is my avatar since it's so big.
My avatar is currently just a random guy it was good art and high quality so i new it could be cut down to the 100x100 size and look good still.
sig is just a comment I use on my GT and what I believe on in the gaming community.
