Oh gosh. It's like choosing between my babies, except you know, without all the stress and guilt XD
Fi's sword is fast, graceful, and strong. Ghirahim's is focused, powerful, and elegant. Young Link's Fierce Diety is awesome, and Link's Great Fairy is hilarious. Shiek and Ganondorf (Swords) are both a blast. I think they're my favorites. That's only 6, so there's still room for me to find another fav. Cia's pretty great, but idk, I'll leave a slot open. I hope I didn't forget anyone lol XD
