Favourites
Link (Skyward Sword, Twilight Princess, and Ocarina of Time iterations)
Zelda (Skyward Sword, Spirit Tracks, and Ocarina of Time iterations; we don't see enough of her in Twilight Princess to get a bearing on her personality)
Ashei (I love her standoffish and blunt attitude, and I think Link having a warrior friend of the female variety is a nice touch for TP)
Fi (She is the consciousness of the Master Sword, and above all, she was immensely helpful as a guide)
Tetra (Okay, so I know she's technically Wind Waker's version of Zelda but she's almost like a distinct character by herself)
Least Favourites
Ganondorf/Demise (In my reincarnation theory post, I explain that Ganondorf and Demise are essentially the same being)
WW Link (Not too fond of him, not that he's a terrible character but my primary favourites are SS, TP, and OoT Link.)
Ghirahim (He was such a pain in the ass, I hated his dramatic attitude)
Zant (Another drama queen, but more retained than Ghirahim.)
Gaepora Gaebora (Anyone else hate that owl, or just me?)
