A "heel" in professional wrestling refers to a character who plays the role of a villain or betrayer. Heels often engage in underhanded tactics, cheat to win, and provoke the audience's dislike. Their actions create conflict and drama, making them essential for storytelling in wrestling. The term "heel" is derived from the idea of someone being low or despicable, much like the heel of a foot. Heels often oppose "faces," or heroes, in wrestling storylines. Famous heels include characters like Vince McMahon and Ric Flair, who have captivated audiences with their cunning and deceitful behavior.
