Lili Rocheford. I love her fighting style. There's something about a street-fighter style being ballet inspired that really makes me smile.
I've also always been a fan of Ling, and Lee. Jin's also pretty high on the list, but only for the fighting style. Kyokushin Karate looks amazing, but his personality makes me gag.
Sadly, since Kunimitsu's not around anymore, or at least not until T6 I hope, I can't really list her as my favourite.
Other than Yoshi,Its Kazuya all the way,Just to say that he's super-Badass is an under-statement
Just to keep the Forum tidy, I suggest the conversation is carried on here
