Anne Hathaway
Consider her Occupy Wall Street's favorite villainess! Anne's Selina Kyle (AKA Catwoman) is a cat burglar who waxes poetic about the socio-economic injustices in Gotham. And looks flawless doing it, of course.
Tom Hardy
"When Gotham is in ashes, you have my permission to die," Hardy's Bane taunts Batman through his signature Darth Vader-esque face mask. Bane is burly, brainy and makes a habit of blowing things up.
Aaron Eckhart
As D.A. Harvey Dent, he was a moral, upstanding (and perfectly coiffed) politico. But murder his fiancée and burn half of that handsome face and it's no wonder The Dark Knight's Two-Face was so pissed off.
Cillian Murphy
Real name: Dr. Jonathan Crane. But add a burlap mask, some hallucinogenic drugs (and hallucinated maggots) and Murphy's mad scientist-type was far more nefarious as Batman Begins' villain Scarecrow.
Uma Thurman
Good girl gone green: Dr. Pamela Isley was all ethics, but douse her in toxins and Thurman became Batman & Robin's Poison Ivy, possessing a toxic kiss and the desire to turn Gotham into a rainforest.
Arnold Schwarzenegger
Schwarzenegger played Batman & Robin's scientist Victor Fries, who becomes Mr. Freeze after a lab accident forces him to don a diamond-powered subzero suit. Oh, and he freezes things (like Gotham, for one).
Jim Carrey
Batman Forever's Edward Nygma develops The Box, a device that allows him to access brainwaves and discover people's secrets. Wielding such power, he becomes the scheming, lime green spandex-wearing Riddler.
Michelle Pfeiffer
Take a shy secretary with a love for cats, push her off the top of a building when she discovers an evil plot, mix in some romance with Bruce Wayne and you've got Pfeiffer's Catwoman in Batman Returns.
Jack Nicholson
Batman's Jack Napier starts off normal (albeit with a sadistic sense of humor) but falls into a chemical vat that transforms him into The Joker (white skin, green hair, red lips included). His M.O.? Death by laughter.
Cesar Romero
Far from the violent villain he would become in later Batman films, Romero's Joker in the 1966 Batman drove a Jokermobile and committed crimes like turning Gotham's water into jelly and challenging Batman to a surfing contest.
Eartha Kitt
Though not the longest running Catwoman on the Batman television series, Kitt donned the trademark cat suit—made black instead of the green used in the comic books—and existed sans any daytime alter ego.
Burgess Meredith
With a laugh meant to mimic the squawk of a penguin and a group of animalistic henchmen, Meredith's Penguin was all camp. His big heist? Commandeering a nuclear submarine that resembled a penguin.
