[PS3] SC IV: Darth Vader

So I'd played and gotten pretty good at Soul Calibur IV on the XBox 360, but I own a PS3, so when I saw it for PS3 at 40% off at Circuit City, I got it. I'm working on unlocking everything and last night I tried to unlock The Apprentice. Is it just me or is Darth Vader completely useless at fighting? I eventually beat the Apprentice twice in a row, but Algol I finally let ring himself out after probably 20 tries. Eventually, I'm going to have to do story mode with Darth Vader for armor unlock credit...
