What should a villain look like?

A villain should embody a presence that evokes unease or fear, often characterized by distinctive physical traits or a striking appearance that sets them apart. Their attire may be dark or ornate, reflecting their sinister nature, while their demeanor is often cold or calculating. Additionally, a compelling villain often possesses a complex backstory that adds depth to their motivations, making them more than just a one-dimensional antagonist. Ultimately, a great villain captivates the audience, leaving a lasting impression through their charisma and menace.
