Ace D. Copular is the former love interest of Buttercup and is the leader of the Gangreen Gang.
Ace (voiced by Jeff Bennett) is the Gang's leader, and a mean-spirited, bullying, opportunistic rogue.. When he speaks, he sounds like the typical juvenile delinquent—mean and disrespectful.
He has a nasally Italian New Yorker accent. As the Gang's smartest member, he is the instigator of most of their antisocial activities, and he does possess a certain charismatic charm that allows him to sweet-talk people who ought to know better, such as Ms. Keane and even Buttercup in the episode "Buttercrush."
