3. Black Cat

And, of course, the Marvel Universe’s femme fatale had to make this list. Felicia Hardy has been the subject of some great comic books and some terrible ones (cough, cough…Spider-Man and Black Cat: The Evil that Men Do…cough, cough), but overall she's one of the best characters out there.

Felicia Hardy was the daughter of a noted cat burglar and trained herself to take after him. She ran afoul of Spider-Man, and faced off with him on numerous occasions, sometimes as a romantic foil. She eventually became a full-on hero in her own right.

She later returned to thievery. But this was around the time Doc Ock was in control of Peter Parker's body as the Superior Spider-Man. Upon apprehending Black Cat, Spider-Man beat her down viciously and severely, leaving Cat with a grudge and a desire for vengeance. After that, she began working her way up as a crime boss.

Good for her.
