Hmm, they're also so different so it's hard to single it down to just one...
Yuna: She's very calm, honest and determined and always puts others before herself. She's very forthcoming with her opinions, in a mature and insightful way, and posseses that inner strength that drives her onwards.
Laguna: he's not up there, but i just love him generally. He has a way of inspiring people with his care-free, upbeat attitude. You can't help but fall for his charms. I also love how heroic and just he is, trying to protect Ellone all the time. And the leg-cramp-when-i'm-nervous thing is just adorable xD I love Squall too (my favourite ff guy <3 ), but his attitude is a little messed up until rinoa opens him up a bit.
Lightning: Who doesn't love lightning's attitude? She keeps a cool head, thinks practically and definately isn't messing around. Like she says, 'a target's a target'. I also love seeing the 'claire' side of her, more caring and compassionate, she has a real reason to fight. i mean, TO KICK ASS.
I can't decide... i guess i'll just go for the obviously right choice:
<3 Snape's attitude ftw.
