Batman Vs. Two-Face is an American animated movie based on the Batman: Classic TV Series and a sequel to Batman: Return of the Caped Crusaders.
Plot[]
This movies begins with Batman and Robin, meeting up with Gotham District Attorney Harvey Dent at a top-secret demonstration hosted by Professor Hugo Strange and Dr. Harleen Quinzel. Strange operates a machine called the "Evil Extractor" designed to siphon evil from criminals and store it in a vat. The containment vat explodes, drenching Dent with liquefied evil, which scars half his face and changes his personality, turning him into the criminal "Two-Face". After being thwarted by Batman and Robin a number of times, Dent is eventually given reconstructive surgery, seemingly erasing the Two-Face personality, and allowed to resume crimefighting as the assistant to the Assistant District Attorney.
Six months later, Batman and Robin capture King Tut and his henchmen for stealing a biplane. Batman, Robin, Commissioner Gordon, and Chief O'Hara interrogate Tut's alter ego, Professor McElroy, with O'Hara constantly hitting the professor on the head with his truncheon to switch his personality. At his trial, McElroy admits his guilt, ready to suffer the minimum penalty of being rehabilitated in prison. After the sentencing, Dent and Bruce Wayne share a highball just before Dent leaves to attend a charity for underprivileged twins at the Winning Pair casino.
A package arrives at Gordon's office; a World Atlas book marked for Batman, with its pages eaten away in three holes. After investigating Bookworm as a suspect, Batman and Robin deduce that the stolen books were all about duality and their suspicions turn to Two-Face. They head to an abandoned sign factory, with Two-Face and his henchmen waiting for them. After defeating the goons, Two-Face pins them with a large number two and the flip of his coin landing on the right side spares their lives. Once they have left, Batman theorizes that several criminals are uniting against Dent for foiling their schemes.
Following Dent back to the lab, Robin is ambushed by Two-Face. Strange corrupts him with some of the liquid evil and Batman is forced to fight and subdue the hypnotized Robin. Robin is cured at the Batcaveand they follow Two-Face to the Winning Pair Casino, where he is revealed to be Dent. Once Batman and Robin are strapped to a large silver dollar, Two-Face unmasks Batman as Bruce and deduces Robin's true identity as Dick Grayson. He invites several other villains to bid for the knowledge of Batman and Robin's identities.
With Catwoman's help, Batman and Robin defeat the villains, but Two-Face gets away on the biplane stolen by Tut, using the evil gas to corrupt the citizens of Gotham City. Batman and Robin shoot him down and with Batman's help, Dent regains self-control, defeating Two-Face for good as they escape the factory.
The next morning, Batman and Robin use the Batwing to cure the infected citizens. Months later, Dent holds a bachelor auction at Wayne Manor, with Batman as the first bachelor. The first bid comes from Catwoman.
In a Blu-ray exclusive scene, Quinzel breaks the Joker out of prison while wearing a costume of her own, having now adopted the supervillain persona "Harley Quinn".
