Cloud. Though he wasn't the worse main character, compared to my favorites (The clashing personalities of Tidus and Squall come to mind) I just didn't like him much. Maybe because Cloud didn't seem as realistic as Tidus or Squall (but all three did mature into grown men), and by realistic I mean, I couldn't compare myself to him. So, even though I could understand how he felt through out the game, there wasn't a major connection between myself and Cloud.
