My favorite boss was Byrne, it was like an epic starwars fight (like Luke Against Darth Vader) because it was in an arena, and you fought weapon against weapon fighting for victory and only victory. Personally I normally like the fights when the boss is the same size as you and your fighting face to face, because it gives me more of a (I'm a great hero and if I fail this I will let down Hyrule) feeling, where as when I'm fighting a bigger boss like Phytops I feel like (oh it's just some beast with mental issues thats good inside and won't do anything to the world). And no I'm not saying there should be big bosses because I like the epicness of them.
Either Byrne or Malladus. They were both pretty hard and fun. Malladus was harder, though, and it took me a while to beat him (even though I beat him on my second try...). I beat Byrne on my first try, I think, but I don't remember. He did take me a while to beat, though. They were both pretty fun, though. =P
are we only talking about ST, coz for me it would be fraaz like people have already said the music is cool and he is pretty hard at first
even though he was easy i like the cactops the barbed menace guy, im not sure why.
