A naturally sunny disposition and generally trust-worty demeanor are definite assets for someone who (before they joined the Rebellion) seemed to spend most their time stealing unattended speeders.

Devon Kismet stands about 5'6" tall and is quick on his feet.  His short blonde hair that needs little to no attention and generally being clean shaven means that he can look respectable in uniform with little effort.  When not in uniform or a flight-suit, Devon tends to wear either civilian clothes or (if he's going to be spending any amount of time in the hanger) the padded flight suit he bought with him when he joined the Rebellion.
