Hugo Strange's Tyger guards have succeeded in apprehending every "outlaw" in Gotham City, except for Catwoman, Two-Face, and Batman. Thanks to a tip-off from Two-Face, a Tyger strike team locates Catwoman's apartment and breaks in to arrest her. She evades them, but the commandos crack her wall safe and steal her most prized valuables. Furious, she confronts Two-Face while he is examining stolen blueprints of the Arkham City security facilities. Despite Batman's attempts to help her, both she and Two-Face are arrested and dragged to Arkham City, Catwoman furiously trying to grab a digital memory card from Two-Face with photos of the blueprints.
Batman confers with Commissioner Gordon, sharing what little he knows of Strange's murky past. Gordon admits that the GCPD is largely impotent since Quincy Sharp declared martial law, and Strange's Tyger guards have become the ruling authority in Gotham City. They are interrupted by Tyger guards, sent to arrest both of them, but Batman has already disappeared, and Gordon appears politely baffled at the accusation that he has been consorting with a known outlaw.
In his private clinic, Hugo Strange interviews several persons battered by Batman, including Arkham City inmates, and his own Tyger guards. The normally implacable Strange is inwardly troubled at how effectively Batman is inspiring fear in his otherwise rational victims, becoming less a man than a phantasm.
An origin story of the Abramovici twins who appear in Batman: Arkham City. Born Siamese twins in the former Soviet Union, the twins were discarded by their father and adopted by a traveling freak show, where they grew into strong and brutal animal wranglers. News of their abilities spread, and they were "liberated" by Joker, who hired a corrupt surgeon named Thomas Elliot to separate them. Joker kept the twin known as "Hammer," while the other, "Sickle," was thrown out into the street, and later recruited by Penguin. While researching this history, Robin comments that it is odd for twin brothers to be working for opposing sides. Batman says the brothers' conjoinment forced them to get along, but that is no guarantee that they will do so after being separated.
