My list is as follows:
1- Vivi for obvious reasons
2- Freya, her lover forgot about her and she continued to fight and an awesome fighter at that
3- tied at 3 the two summoners Eiko and Garnet
4- Steiner and Beatrix the lovely warrior couple
5- Quina, I think it's a she. She eats frogs and is one of the funniest characters around
6- Zidane, yes he's the main character, yes he has a cool tail, but you have to admit he's kind of annoying
7- Everyone else, they're just ultimately forgettable in my oppinion
