Darth Vader is a powerful Sith Lord who commands the Galactic Empire's armies with an iron fist. He is feared throughout the galaxy for his ruthlessness and tactical prowess. His cold and calculating nature masks a deep sense of anger and pain that drives him to seek power and control above all else.

For reference, I can't say I have anything in mind. Perhaps reference his voice from his various appearances but I have nothing specific I'm looking for. If you can do a fitting voice (impression or not) and it works I will definitely consider casting you.
(Please record various grunts for attacks, being hit, and death)
