Which part of the game had the best final boss?

Actually, my favorite boss is Darth Nihilus from the second game. When I learned about his power, I was simply amazed! I wish I had that kind of power!:cool:

But as a fighter, he's a pushover! He just has a lot of HP, but otherwise, I tore him apart like a hot knife through butter... And besides, he's not even the final boss!
