Hah, I love so many random NPCs it's not even funny.
I'm particularly fond of the Koroks in WW, though.
I've mentioned this a few times on some different threads, but they're just so freakin' cute with their leafy faces and tiny instruments.
...But I guess if we're going with a specific person, then I guess I'd say either Makar, for obvious reasons, and that he's super adventurous and courageous despite his size,
this little guy, or the Skull Kid from TP. He's a bit more devilish than the ones in OoT, but I doubt he'd have any interest in picking up the most dangerous mask in existence.
