Quistis from FFVIII. She's a bit overshadowed by other characters but, actually her Blue Magic can be very useful. Also, Tifa from FFVII: I love the challenge of playing Actively in ATB (time isn't paused while you decide your moves) & trying to get all 7 of her Limit Break reels to "Oh Yeah" during a big boss fight!
Squall for sure!!! Of all the characters he is the one to wich my personality looks closer, and also, I'm physically similar, (not Identical) to him, so every time I would play FFVIII I would imagine Squall as being me do to the similarities. :) My friends even say I look like him, no kidding,
I'll be my favourite Final Fantasy character, Kefka Palazzo, I'm also very articulate. And I like wearing costumes as he looks like he's wearing a costume.
