Exactly. That what makes him SO AWESOME!
I think the best part about him was his voice. His voice is soooo cool.
I always dreaded fighting Sion, in-game. He's really tough, but I developed the perfect strategy for Jedi Masters. So he's not so tough anymore.
As for his voice. It is really good, but I prefer Kreia's. Superb voice-acting in that game.
