This guy.  This guy makes sure the X-Wings don’t run out of gas.  Or whatever.  Why did they wait until right before launch to fuel up?  They were on a secret base that had to be prepared to scramble fighters at a moment’s notice.  Shouldn’t they all be full all the time?  Maybe it’s special fuel that can’t be left in the tank.  Or maybe it’s Tibanna gas.  For the lasers.  Anyway, that’s what this guy did.

He’s a pretty standard tech, but if you look up 1977 in a dictionary, there’s a picture of this guy.  That 70’s adult film look is prevalent throughout ANH, and is one of the things that adds a bit of sweaty realism to a space opera about magic powers and laser swords.  That’s why Hasbro needs to make this guy.  Or not.
