With Batman gone and the city's criminals behind bars, Catwoman moves to settle a personal score. Still furious at the Riddler for holding her hostage, she tracks down his headquarters—concealed beneath Winslow's Toy Shop. After obtaining the necessary key cards and knocking out his guards, she slips into the hidden entrance to his underground robot factory.
Riddler, still sitting in a GCPD cell, realizes too late what is happening. Attempting to disguise a call to his factory's AI as a conversation with his lawyer, he tries to command his Riddlerbots to break him out. Catwoman gets him on the phone and spells out her plan: empty his accounts, destroy the factory. Enraged, Riddler activates every countermeasure—Riddlerbots, lasers, an electrified floor, and a giant buzzsaw mechanism. Catwoman dismantles them all, drains his bank accounts via the main computer, and triggers the factory's self-destruct. Left fuming in his cell, Riddler is tasered by Cash, who has caught on to his schemes.
