Batman: The Animated Series

Batman encounters a new cat burglar calling herself Catwoman, and around the same time, meets a woman named Selina Kyle (as Bruce Wayne), to whom he is visibly attracted. When Selina runs into trouble with a terrorist group known as The Red Claw, who want the mountain lion sanctuary she was trying to protect, she decides to take matters into her own hands and investigate.

A mysterious bat-like creature terrorizes Gotham City, causing the police force to pursue Batman. The Dark Knight must find the real perpetrator to clear his name.

Bitter scientist Victor Fries, as Mr. Freeze, attacks several divisions of GothCorp, each time stealing a piece for a secret weapon he intends to build. Batman investigates the connections, and discovers that the start of Freeze's vendetta against GothCorp was a bitter falling out between Fries and GothCorp's CEO, Ferris Boyle (Mark Hamill), during which Boyle almost killed Fries (mutating him into Freeze) and presumably killed Fries' terminally ill wife, Nora. Batman must find a way to bring Boyle to justice before Freeze carries out his revenge.

Bruce Wayne is framed for the attempted murder of Lucius Fox. The real perpetrator is an actor and master of disguise named Matt Hagen, who was disfigured in a car accident years ago. In order to keep his fame, he secretly started working for Roland Daggett, who provides him with a monthly supply of an addictive face cream known as Renuyu (a pun on "Renew You") that can temporarily reshape his face back to normal, and who wants to take Wayne Enterprises over for marketing expansion. For botching the murder, Hagen's supply is cut off, and when he breaks into Daggett's lab for more Renuyu, he pays the price dearly when Daggett's men drench his face in the formula and force him to swallow liters of it to avoid drowning. Meanwhile, Bruce Wayne is arrested and taken into custody, charged with the assault on Fox.

Bruce Wayne is released from prison on bail. Hagen, as it turns out, survived the murder attempt on him, but at a high cost: the formula entered his body and soaked every single one of his cells, turning him into a shape-shifting mutant. With his newfound powers, Hagen, now calling himself Clayface, decides to take his revenge on Daggett and his men. Can Batman bring Daggett to justice and stop Clayface before innocent people are hurt?

A mob war between crime bosses Rupert Thorne and Arnold Stromwell is nearing its end, and comes to a climax when Stromwell is set up to be killed in an exploding restaurant by Thorne. Batman saves him at the last moment, and aided by Stromwell's brother (now a priest who lost his leg years before, an accident for which Stromwell carries a secret guilt), tries to persuade him to give up his life of crime and help the police bring Thorne down by testifying against him.

After a man named Charlie Collins curses at the Joker on the road for bumping him, the Clown Prince of Crime corners him and intimidates him into doing him a "small favor". Two years pass, and the Joker finally decides how to use Charlie: to sneak a bomb into the Peregrinator's Club, where Commissioner Gordon is to give a speech at an award ceremony. Charlie, who merely has to open the door, is skeptical at first, but for the sake of his family, he reluctantly decides to obey. But is the Joker really the type to let someone who insulted him live?

The leader of the Red Claw group (known herself only as Red Claw) attacks a military train and steals a viral plague, which she intends to release in Gotham if she isn't paid a ransom. Can Batman and Catwoman put aside their differences and work together to stop Red Claw before it is too late?

When District Attorney Harvey Dent collapses after a meal with his fiancée Pamela Isley and friend Bruce Wayne, doctors discover that he has been poisoned. Batman must find the culprit and the antidote before the DA's time runs out.

Batman encounters the Scarecrow and attempts to foil his scheme to burn down Gotham University, but in the process is exposed to the Scarecrow's fear gas, and is forced to face his own guilt over the death of his parents.

Mayor Hamilton Hill's miserable son, Jordan, becomes even sadder when his father uses his birthday party as a political gathering, and ends up stowing away in the truck of the party clown hired by Hill for the party, whom he doesn't know is actually the Joker in disguise. It is now up to Batman, whom Mayor Hill distrusts, to rescue the boy before it is too late.

With the help of arsonists, Roland Daggett plans to destroy Crime Alley and use the land to expand his business empire. But that plan would mean killing the residents or forcing them to abandon their homes. Now, Batman must foil Daggett's plan and try to prove that he is a criminal.

A botched police operation results in the suspension of those involved: Officer Wilkes, Officer Montoya, and Detective Bullock. Confronted by their superiors, each of them is forced to tell their tale of what happened that night.

After his company goes bankrupt, Temple Fugate becomes the Clock King. Fugate sets out to seek his revenge against the man whom he blames for his misfortunes: Mayor Hamilton Hill. Fugate kidnaps Hill, intending to do away with him to accomplish his revenge. Batman must stop Fugate from carrying out his revenge and save the mayor's life.

Joker creates a toxin that affects only fish, mutating them into Joker fish. Then, he targets innocent men who refuse to copyright his Joker fish. The Joker also captures Harvey Bullock, and Batman must rescue him and foil the Clown Prince of Crime's insane scheme.

Several rich industrialists are invited to the Eternal Youth Health Spa, and that's where they are last seen before disappearing. The only connection: they had something to do with the death of plants. Bruce Wayne also receives an invitation (although it was one of his greedy directors who nearly made the deal to destroy a rainforest before Bruce forced him to shut the operation down), but Alfred and his "lady friend", Maggie, go in his place. When they do not return, Batman is forced to investigate, discovering that the spa is run by Poison Ivy, and that she has been using a formula to turn the industrialists into humanoid trees, including Alfred and Maggie.

Mobster Rupert Thorne attempts to use Harvey Dent's secret split personality to blackmail him. But when Dent meets with Thorne at a chemical plant, "Big Bad Harv" takes over, and the resulting confrontation leads to an explosion that horribly scars half of Dent's face.

During a fight with Batman over a stolen Fabergé egg, the Penguin incapacitates Batman with poison gas.
