My favrite is Ganon The Evil King! This boss is really cool it is a harder boss than some other bosses. It is not one of those bosses that seem to be impossible, but it is not one of those bosses that is not challenging ether. You get to fight this cool boss in the oracle games but only in a linked game. His moves are strong some you will remember from some other versions of Ganon. For example he will disapear like Zelda I, but he reapears to attack. He also use a trident link in A Link to the Past. However he dose have his own unique attacks for example he has an attack that makes the floor rave a blue and light blue and reverses your walking controls and I think damage is increased. I mean how cool is that!
*I like Bongo Bongo from Ocarina of Time *That eel looking boss from Twilight Princess ( water boss ) *That golden armor boss with 6 arm's and holds giant swords in Skyward Sword * That sand snake from Wind Waker * Zant from Twilight Princess * That Indian weird dude that has and sword and a shield for an weapon boss in Major's Mask . ( Woodfall Temple I think ) lol * The Bird King from Wind Waker
and a couple of other's . I seem to never remember the bosses names
