Bossman is the leader and general spokesman of the Amoeba Boys. He is the largest and most talkative Amoeba Boy and wears a gray fedora. Bossman is based loosely on Edward G. Robinson and Al Capone, he can be described as the Mastermind, despite the fact he is not much more intelligent then his fellow gang members. Bossman would love nothing more than to be regarded as a serious villain worthy of fighting, and even getting beaten up and sent to jail by the Powerpuff Girls. Unfortunately, his brain is far too primitive to devise a crime above the level of littering or jaywalking. He once spent weeks planing a heist to steal a single orange from a fruit stand. Bossman and his gang are definitely one of Townsville's least malicious villains, even having an unintentional friendship-of-sorts with The Powerpuff Girls. He is generally harmless, but his actions have on several occasions endangered both the girls and the town purely by accident. Such as when he wanted to commit the 'Crime of the Century' by standing next to a "Keep Off the Grass" sign all night, but then turned into viruses after being caught in the rain and spread a plague throughout Townsville. Despite this incompetence, Bossmans dose however act like a mob-boss, he is the brains behind the whole operation, and often smacks his gang members after they commit acts of failure or stupidity.
