I would much prefer Tom Nook over anything else Animal Crossing has to offer, just because he isn't generic, he's cute, and he shows up in most of the games (I think). Similar to Tingle. Not IMPORTANT, but has a fanbase, and shows up a lot.
Also, I can see why people like Ghirahim, he has a definite personality, something a lot of Zelda characters lack. He also has a moveset that writes itself. I actually think PHI would be a cool character as well. She's very elegant, and skaty. I love her demenor as well. Still doubtful for LoZ characters in general, but Ghirahim has likeable traits, definitely. I don't think he's going to be TOO WELL RECIEVED here though. Oh, and I would like to note, I've had like, 25 votes since last week on my poll, none of them being Ghirahim.
