10. Catwoman, 'Batman'
Cats have nine lives, but all it took for this particular kitty to attain pop-culture immortality was three. Actresses Julie Newmar, Eartha Kitt, and (in the big-screen cash-in movie version) Lee Meriwether each slipped into the black catsuit and slinked their way into the pantheon of Batman villains — no small feat, given that the Caped Crusader has the strongest rogues' gallery in the entire superhero genre. Of course, compared to Cesar Romero's Joker, Frank Gorshin's Riddler, or Burgess Meredith's Penguin, Catwoman certainly had sex appeal on her side, but there's more to her than that. Any connection between this femme fatale and feminism was likely unintentional on the part of the producers, but the way her feline wiles made total fools of the Dynamic Duo spoke, or purred, for itself.
