That one guy in the woods in ALttP who plays the flute for the animals. That felt like such a tragic fairy tale, love that mysterious feeling.
Honorable mention to the hobo under the bridge in several games.
Any character that screams in a high pitch.
Tingle, King Daphnes, WW’s Deku Tree, Selmie(was that her name?), the door butler, Tetra, Happy Mask Salesman, Quill, Marin, Cremia, Medli, the Subrosia s as a whole, Riju, Ezno, probably many more I like but those are off the top of my head. Kinda hard pressed for characters I’m not too fond of tbh…maybe Collin, something about him just makes me angry, but the other kids in TP aren’t great either, except for the creepy baby.
My favorite character is Saria (duh i know), Midna would be second and honestly I like most of the main characters and some side characters. I guess the ones I don't care THAT much about are Beedle and Tingle. They're ok, but yeah...
