Baltheir for me. I hated him when he first joined the party,but as I got further in the game i started to like him a lot. Ended up being my second favorite character in XII behind Basch of course.

i hated ashe from XII as a character...wait i still do...

one character who my opinion of changed is actually eiko from IX, at first she was annoying as hell, but then the sympathy thing (almost last of her kind) kicked in and i liked her a teeny bit more than before

I hated Rinoa because she just used to annoy me. I was never a fan of Rinoa/Squall but then the ending was just so sweet. Now I can (sort of) stand her.

At first, I really despised Garland. I thought he was cruel to not just Zidane, but Kuja as well. But then when he died, I actually felt bad for the guy. He was just trying to save his planet, but had a horrible way of doing it.

I really hated Eiko ate first, too. I thought she was a little brat. But then after a little while I found her very comical, so I started liking her more.

Quina Quen. >.>

At first I thought s/he was annoying, but then s/he started to make me laugh.
