The term 'Villian' is often used to describe a character in a story or movie who is the antagonist, or bad guy. In crosswords, two words that can be used to describe a villian are 'OGRE' (4 letters) and 'MEANIE' (6 letters). An OGRE is a mythical creature that is usually depicted as a large, ugly, and mean-spirited monster. A MEANIE is someone who is unkind, cruel, or unpleasant. Both of these words can be used to describe a villian.
