Since I only played JO and JA, I can't vote on any DF2 villains. In JO, I guess it was Desann, because the Tavion duel was kinda generic, don't even remember the Galak one tbh. Though honestly, it was neither. In JA I liked the Rosh one, because it's fun whooping his arse, and because the Kothos twins were healing him and "pushing you around" if you tried getting to them, so yeah. The possessed Tavion one was just pathetic, because you'd think the infamous Marka Ragnos would be A LOT stronger...
