Zant. Finally able to smash that looniness off his face was epic, even when I almost fell out of my chair, laughing his reactions. Still, had it been the final battle, without Ganondorf, it would be all the better. The possibilities would have been limitless with him as the ultimate boss.
Also, don't you think his ever-changing stage would be an epic inclusion for Brawl, or SSB4?
I always thought having a good sword fight with mini-bosses & Bosses, Like the darknights on some of the games. I had alot of fun Sword-fighting with Gandorf on Twilight Princess, especially since the Golden wolf taught a bunch of moves!
