Even when Darth Vader comes out on top, I wouldn’t exactly call him happy. Once he becomes more machine than man, emotions other than anger and hate take the backseat. Vader views everything Anakin Skywalker was as a weakness. I never imagined him smiling, but Replica Props Forum (RPF) user bubba fett did. He worked with a friend to make a smiling Vader helmet back in 2011 for Steve Sansweet. I’m surprised by how natural the smile looks on Vader’s face. You can see a couple photos below, and there are more at his RPF build thread.
