Darth Vader & Darth Maul vs. Aliens
Here's some flat out outstanding fan art from artist Robert Shane a.k.a. rhymesyndicate. The first three pieces feature the Sith getting tangled up with Aliens and Muppets. If Darth Vader and Darth Maul showed up in Prometheus, that would have been insane! In a good and bad way. I've also included a couple more pieces of just straight up badass Star Wars art as well.
Who do you think would win in a fight, a Sith Lord or Aliens?
