Tim Burton’s Batman: Mask of the Phantasm (1995)

Batman, the costumed crime-fighter who prowls the night skies in Gotham City, soon finds there's another vigilante in town knocking off prominent mob figures. Despite the scythe-like blade for a hand, a mechanical voice and the cloud of smoke that follows the figure wherever it goes, the police and outraged officials mistake the homicidal crusader for Batman himself and demand that the city's longtime hero be brought to justice. Meanwhile, Andrea Beaumont returns to town. She is the lost love of Bruce Wayne, the billionaire playboy who is Batman's alter ego, and was an integral part of Wayne's decision ten years earlier to don the cape and cowl. Now, she is back in his life and is no less a disruption than the return of his old archenemy, The Joker, who has a stake in seeing the annihilation of this new vigilante, whoever it proves to be.
