Guts isn't really much of a badass, at least not in the anime. He loses a duel to Griffith and becomes his bitch. Later he leaves, but when Griffith gets in trouble he comes to his rescue.
He was a strong fighter, but his personality isn't really that Gar. Griffith is actually far more badass than he is, although he looks like a faggot.
On top of that, as soon as I saw the initial bracket, I knew Guts was going to win, so I did what I could to fight fate. Granted I failed, but I managed to get a lot of people on my side and generate LULZ.
