Feel free to name options not included in the poll. The options I included are just my best guess as to what most fans would consider the S-tier bosses of the series. For the purposes of voting, the poll options represent all phases of their respective boss fights (for instance Ganondorf OoT includes the Ganon portion of the fight.)
Personally, I really love Blizzeta from Twilight Princess. She's unique in that she's not simply some monster waiting in an arena, nor a character clearly intended to be an antagonist from their introduction. She just seems like a charming NPC who provides a rationale for Link to collect soup ingredients around Snowpeak Ruins and then, well, you know what happens. The way she's corrupted by the mirror also builds suspicion in your initial play through about the extent to which Link should be trusting Midna, which is an interesting unreliable narrator angle other Zelda games have never touched. Midna is the only character in the series who's made me question if I'm acting in my best interest as I play the game, and the way Blizzeta's reaction to the mirror bolsters that concern is a pretty masterful touch that ties your fight with her into that broader mystery. I also think the use of the reflections in the ice partnered with the ball-and-chain item is a fun, clever way of handling the boss fight, so it's still mechanically satisfying in addition to its exceptional story integration. Finally, the conclusion with the two yeti lovebirds reuniting is far more heart warming and enjoyable than the usual conclusion of a monster bursting into a puff of smoke as you sheathe your sword. 10/10, no notes.
