Batman Returns
A couple throws their child into the sewers because he is a deformed monster that killed their cat and showed violent tendecies. 33 years later, the child becomes the criminal Penguin. He kidnaps businessman Max Shreck, blackmailing him into helping him become a citizen of Gotham City using evidence of his corporate crimes. Meanwhile, Max finds out his secretary, Selina Kyle, has found out he is planning to build a power plant which will drain Gotham City of its electricity. Max pushes her out of a window, ensuring that she will not tell anyone. However, a flock of alley cats lick her semi-corpse, reviving her. She returns home, suffering a mental breakdown, becoming the antiheroine Catwoman.
