Boring bosses kind of bring a game down though. It's really anti climatic when the normal enemies you cross paths with in the game are more of a challenge than the massive tentacle monster than pwns "The Albino B@#%!" with a gut pierce to chomp combo.
Odin Sphere had some good last bosses that tied in with the story.
Legend of Zelda: WindWaker to me, has the best Ganon fight ever.
SMT:DDS 2 boss of the main story line was a pansy. Satan, however is not.
Most of the Megaman Battle Network games had good bosses too. The special versions that you fight are no joke.
With Muramasa: The Demon Blade, Momohime had to go up against cooler bosses. Her endgame one is harder IMO.
The World Ends With You had an interesting end game/special boss.
