During the attempted capture of Boss Grissom’s murderous enforcer Jack Napier in the miasmic Axis Chemicals building, Batman inadvertently assists in the creation of Gotham’s first super villain. Napier, disfigured by his own gunshot ricocheted from Batman’s gauntlet, tumbles into a vat of chemicals to his apparent death. Later, Napier, now the Joker and driven insane by his permanent rictus and bleached skin, murders Grissom and establishes control of Gotham’s organized crime syndicate. Batman succeeds in rescuing Vicki Vale from the Joker’s clutches, transporting her via Batmobile to the Batcave where he reveals a solution to the Joker’s Smilex-tainted hygiene products. Batman later utilizes the Batmobile’s deployable bombs to destroy the Joker’s chemical refinery.
