Ace is the leader of The Gangreen Gang (a gang of monstrous teenaged hoodlums that are green-skinned and disreputable and unhealthy looking (as if suffering from gangrene). In addition to being the Gang's leader Ace is a mean-spirited, bullying, opportunistic rogue. He sports a long, straight, greasy, slick-back hairdo, a scraggly mustache, a colored vest-jacket, a pair of shades and even fangs. 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. His full name is Ace D. Copular, he is 17 years old - the oldest of the Gang.
