I made this a while ago, but I dug it up from the depths of my origami drawer. It uses the Nathaniel W Base, but is really easy! I already decorated it, so if it is hard for you to tell how to fold it, say Fizzpop. The first and last photos are actually not part of the steps, but the first one tells you that you need a quarter of a sheet of paper. Enjoy!
P.S. Mandomaker, could you do stormtroopers vs. clone troopers? I think that would be interesting.
