This is a bust (like taytays!) created by artist Ryan Renders of Darth Vader and Skeletor's lovechild. Now I'm not sure who was the top and who was the bottom in the relationship, but Skeletor doesn't wear anything but a hood and a loincloth -- you do the math. "Yeah but Vader gets all soft at the end of Return of the Jedi -- he was probably the bottom." Okay you are getting way too in depth on this.
Hit the jump for some close-ups.
