In "Legends" material, Gavin Darklighter is the cousin of Biggs Darklighter, and would go on to become a pilot in Rogue Squadron.

Just some minor tweaking and part swapping here really. I had to do some minor trimming to the neck post for the head to fit properly. I always thought Gavin had black hair. According to Wookieepedia, he is listed as having dark brown hair so I left it. I'm very happy with my head selection and the helmet fits perfectly. As you can see, I like to be accurate as possible - the helmet is the same and the flares are on the right leg.

Head: GI Joe Major Barrage
Body: The Black Series Jon "Dutch" Vander #10
Helmet: Luke Skywalker VOTC
