Boy, Sephiroth, the bad guy. What can I say? He's awesome though. He has caused a lot of damage to the lives of many. He's killed many. And he's tormented Cloud's messed up head for years. He was Shinra's Ace and Soldier's main man. He kills the president of Shinra and is the one who causes Meteor to come. He uses the Masamune, which only he can handle.
