Squall is the most emo one that comes to mind, because he was so anti-social and thought everyone was stupid for depending on other people.

I find it funny people are calling Cloud emo to vent their hatred for FFVII when throughout the whole game he was always acting cocky, or trying to be the "cool guy".

Even with 8, I don't think FF is emo. Melodramatic at times, yes, but none of them ever made an album or tried to kill themselves because their girlfriend broke up with them...
