Wow, it looks like Midna is really polarizing, I didn't expect that. I'm going to throw this out there, he may not be my absolute favorite, but I think he deserves some long overdue love.
Favorite-ish = Ralph: This is the dude. Howcould you not love this guy? Ralph is the Samwise Gamgee of the Zelda series. He's uncompromisingly loyal to his charge, exceptionally caring regarding Nayru, and totally courageous, even going as far as to apologize for his fear and actions to the man he sees as his rival. He needs to be in Hyrule Warriors 2.
Least-favorite = That Woman In Kakariko Who Narcs On Link: That jerk! I hate this chick! "Oh no, it's the totes-dangerous-and-absolutely-not-at-all-altruistic-demon-of-a-boy-who's-absolutely-come-to-murder-me-and-desecrate-my-corpse: Link!!! Come kill him!" This chick needs to leave and head straight for a patch of quick sand.
