Without a doubt in my mind, my favorite villain is Sync, from Tales of the Abyss. 8D It really was a shame that he wasn't playable and we had to take him down. =( But Sync is just awesome. He's like what, fourteen, and people take orders from him, which is funny whenever he does it to Asch. Also, I usually don't like fists as a weapon, but he makes it so great. Plus, he has greeeeeeeeeeeen hair. =D Hands down the best villain ever!
