There was 2 villains

the dark knight is one
Yes along with Catwoman
The villain...
Bane played by Tom Hardy,
The two villains are Catwoman and Bane.
The villain in "The Dark Knight" is known as the Joker, portrayed by Heath Ledger.
No- Catwoman who will be played by Anne Hathaway is going to be the female villain.
The villain known as "The Joker" did not feature in the film "Batman Forever". He does however appear as the main villain in the films "Batman" and "The Dark Knight" being played by Jack Nicholson and Heath Ledger respectively.
Batman was trained in the mountains in "Batman Begins" (The Dark Knight's prequel) by Henri Ducard (played by Liam Neeson) whom was later revealed in the movie to be batman villain Ra's al Ghul.
I heard Christian Bale is itching to do another but he thinks it will be VERY hard to surpass the Dark Knight and to surpass The Joker as a villain so, it is all up to Chris Nolan of what he says.
A black knight is a term used in fiction for an evil character or villain.
