There are so many memorable characters in Zelda history...
What about Marin [http://zelda.wikia.com/wiki/Marin] (a.k.a. definitely-not dream Zelda)?
or the other Marin, I mean Malon [http://zelda.wikia.com/wiki/Malon] and her sister (vague sexual innuendos!)?
or the other other Marin, I mean Medli (brainy bird-beaked bard bairn)?
or Colin and his family (so darned cute!)? not to mention Malo, Talo, and Beth...
or Biggoron (just give me the blasted giant sword already!)?
or the Great Fairy/ies (even more vague sexual innuendos! ...this time from a giant, naked, floating chick with triangle boobs!)
or Valoo the Dragon? (freaking dragon! and only mythical guardian-beast to help you with more than just words of wisdom!)
or Manbo the Mambo Mambo(fish) and his awesome song, Manbo's Mambo!
