villain

n. scoundrel, wicked person; scoundrel in a story or play

A villain is an "evil" character in a story, whether an historical narrative or, especially, a work of fiction. The villain is the bad guy, the characters who fight against the hero. A female villain is sometimes called a villainess.A villain's disposition towards evil distinguishes them from an antagonist. For example, Javert in Les Miserables is an antagonist: He opposes the hero, but does so by such means and under such pretexts as not to become entirely odious to the reader; a villain may, in fact, even repent, be redeemed, or become a "good guy" in the end. (A villain is virtually always an antagonist, but an antagonist is not always a villain.) The villain is also distinct from the anti-hero, a character who violates the law or the prevailing social standards, but who nevertheless has the audience's sympathy (and may be or become good-hearted), and is therefore the real hero of the story. Sometimes, a villain may even appear as the protagonist of a story, while the hero who opposes them may be the antagonist.
