Blizetta. She's not truly evil, just possessed at the time of battle. We could go snowboarding together and eat pumpkin and ordon goat cheese soup and live in a mansion. Such is the life.
Assuming Ganon is a viable choice, I would choose him. I would utilize the times that he controls everything to basically do whatever I want (Milk and Cheese style). I would conveniently lose all connection with him after he would lose to Link, and re-establish friendship when one of his minions revived him. It would be the perfect powerhouse of exploitation.
An ironknuckle. I would especially like one with Naboru inside because well shes HOT! And everyone would be scared of me because i have a friend with an axe.
I would say Ganondorf because my plans of world domination combined with his plans of world domination leads to mega world domination and we will rule over all of you. Mwahahahaha.
