Albedo's great. Nothing says maniacal like a guy who severs his own head and then taunts you with it.

I was really happy for Allen in Episode III. Finalllllly he stands up for himself! And it's an awesome scene. I also liked that at one point you got to use him as a guest party member.

My favorite villain was Virgil. I'm so happy they brought him back and fleshed out a good back story for him.
