Batman

As the rope Robin is sawing away is near it's end, Catwoman asks Batman if she will take her offer join her and be subjected to the Cataphrenia like she did with Robin. Having little alternative, The Caped Crusader acquiesces just because he doesn't want his own death to be at the hands of Robin. Catwoman orders Robin to stop sawing as Robin frees Batman. Before Catwoman scratches him with Cataphrenia, Batman states that he feels a headache coming on and takes an aspirin (which is actually a Universal Bat-Antidote). When Catwoman scratches Batman, she is unaware of the ploy as the Universal Bat-Antidote allows Batman to keep his reason.

Pretending to be under The Catwoman's spell, Batman accompanies the gang to The Old Criminals' Home to visit "Little Al," from whom Catwoman hopes to buy the plans to the GC Mint. Batman phones an anonymous tip to the police informing them where they can capture Robin and Pussycat. Knowing that The Boy Wonder is now safe, Batman sets a trap for Catwoman who convinces him to take her back to The Batcave. Batman ends up giving her some Bat-Gas which puts Catwoman to sleep.

While in The Batcave, Batman diverts a phone line instigated by the police trying to trace him to the cave, leading the cops right to the place of inventor Pet Pending whom they arrest. After a tour of The Batcave, Batman Bat-Gasses Catwoman to sleep and leaves a note for Alfred Pennyworth ordering him to deliver The Bat-Antidote to Robin at Police HQ.

Returning to Gotham, Batman and Catwoman meet the rest of the gang at The Mint. Using a hidden entrance detailed in Catwoman's plans, they enter the building with plans to loot the whole safe! They blast their way into the vault with a silent explosive, where they are confronted by Robin (now restored to his faithful crimefighting old self again thanks to The Bat-Antidote). Batman drops his charade and states to Catwoman that the aspirin he took was his Universal Bat-Antidote which negated the effects of Catwoman's Cataphrenia. The Dynamic Duo make mincemeat of The Catmen. But just as the police arrive to collect the crooks, Catwoman steals Batman's keys and escapes in the Batmobile. Commandeering O'Hara's squad car, The Dynamic Duo give chase through The New Guernsey Bridge, but realize the impossibility of gaining The Batmobile's top speed, so they use The Batmobile's remote control to stop the car at a waterfront building. The Catwoman takes chase by Batman and climbs to the roof to avoid capture, but she is overcome by vertigo! Here she proposes marriage to The Caped Crusader, which he rejects only when she suggests killing Robin to make their lives together purr-fect. Pretending to surrender, Catwoman reaches out for Batman's hand and deliberately slips, falls, and disappears into the water below.

After Pussycat and the other henchmen of Catwoman are taken to jail, a discussion between Batman and Commissioner Gordon states that Catwoman's body was never found.
