Harley Quinn (Dr. Harleen Quinzel) is a fictional DC Comics character with a playful, chaotic, and mischievous personality. She has a distinctive look that often includes blonde hair styled into two pigtails, frequently colored red and blue or red and black. Her outfits vary, but she is commonly shown wearing a jester-inspired costume or a red-and-blue/black-and-red outfit, sometimes with a baseball bat as part of her signature look. She is energetic, unpredictable, sarcastic, and theatrical, with a tendency to turn almost anything into a joke.
