My favorite villian now is probabely Ghirahim from what we have seen of him so far. He is an very intimidating the way he catches Links sword between his two fingers and how he walks slowely and confident that he will kill his opponent. He is also very flashy the way he was designed, kind of like a prince or a court jester. He is also very arrogent which also reminds me of a prince like attitude. Ganon(dorf) still comes at a very close second. Ganondorf was more of brute power than Ghirahims grace in battle. Of course Ganon does have the Triforce of power which kind of dements his overall attitude toward brute power. In the end though Ghirahim still wins for my number one favorite villian, I can't wait to see him in Skyward Sword.
