I actually tried to make a Samurai Vader in Soul Calibur IV and VI. It was nowhere near as good as this of course but I was proud of it. Had a nice deep voice and glowing red eyes.
I did do one goofball thing and give him a huge poofy red afro so that if his headgear ever broke in game, it'd show up. It was funny as hell whenever my friends and I played SC and they broke Samurai Vader's helmet and saw that afro. Usually gave me the opening while they were stunned from laughing to slay them. Exactly as I had foreseen. :)
