A Star Wars Character

Ok, I made this character for the Star Wars game (or was it a book?) and I have to confess I have no memory of it anywhere.

Lucasfilms sent me some super secret photograph of the actual costume design, but I don't remember this guy in any of the movies or the series, and I've seen them all.

Maybe it's just my damn head, but if you can shed some light I'll be grateful.
Anyway, the design changed halfway through, so I made quite few versions of this.
