His design weakened a lot in my book after he wore Billy like a skin-suit. He never had as much aura as in Mortal Folly, when he was really just an evil, ancient, scary guy. It's like the rest of the show got darker over time, but they made him less scary every appearance, more cartoony. Don't get me wrong, his speeches go hard, but I wish he had returned to the OG look. I will never stop loving that intimidating, peeling mouth and those cold, freaky eyes under his tattered hood.
