The typical episode usually begins with the duo's arch-nemesis Bighead, a criminal mastermind with an abnormally large cranium. Bighead is usually briefing his henchmen on a plot for some grandiose plan for world domination, interrupted by a debate as to whether or not Ace and Gary (The Ambiguously Gay Duo) are gay. Once the crime is in process, the police commissioner calls on the superheroes to save the day, often engaging in similar debates with the chief of police.
