A "Bad Guy" or villain is a character in stories, movies, or games who opposes the hero or protagonist. Villains often have malicious intentions, seeking power, revenge, or chaos. They can be motivated by personal grievances, greed, or a desire to control others. Common traits include cunning, ruthlessness, and a lack of empathy. Villains can take many forms, from classic characters like Joker in Batman to more complex figures like Darth Vader in Star Wars. Their actions drive the conflict in a narrative, making them essential for creating tension and excitement in the story.
