• Detective Harvey Bullock, GCPDThough his colleagues will all swear that Harvey is a good cop, the man is a wrecking ball with a badge. If your money is white, Harvey's been known to look the other way. Subjects guilty of being black on a Friday night have complained about excessive force, false arrest, and outright burglary. And Harvey's ties to organized crime make it questionable just where the man's loyalties lie.
• Anthony "Fats" ZuccoThe man behind an extortion racket that spans Gotham, Bludhaven, and Atlantic City. His mafioso gang was behind the Haley's Circus massacre in 1967. He's opposed to the Falcone Family, the mafia from which his own upstart organization broke off from.
• Waylon Jones (Killer Croc)One of the circus "freaks" who toured with Haley's Circus, Waylon's monstrous appearance appealed to audiences, who paid to watch him wrestle crocodiles. Unhappy with his pay or "side show" status within the circus, Waylon fell into working for Tony Zucco's gang as muscle. This made him a suspect when the Flying Grayson's death in 1967 opened up an investigation by both police and the Batman, driving Jones underground.
• "Mother" (Real Name Unknown)A kindly old lady who volunteers at an orphanage-turned-school-for-girls in Bludhaven, connected with St. Bernadine's Church and the Gotham Diocese. In reality, she's one of Falcone's lieutenants and singularly responsible for all human trafficking going in or out of New Jersey's ports.
• Victor ZsaszA serial killer who makes a mark in his own flesh for every victim. He's worked for Zucco, Falcone, and a few other names in the Gotham underworld, but he's too violent and extreme for even the mafia.
