Ok I always ask myself, Can Darth Vader's armor break? No. And Darth Vader and Yoda are the only way to unlock the "The Apprentice" Darth Vader will take you forever to get him, it took me 14 times. To unlock the Apprentice you have to beat Arcade matches 1-5 vary but 6 is Siegfried, 7 is The Apprentice, and 8 Is Algol He Uses the Soul Edge(Nightmare) and Soul Calibur(Siegfried). Hope my info has helped most of you gamers.
