Imagine a playful yet edgy Harley Quinn profile picture, set against a swirling background of vibrant neon colors. Harley is front and center, with her signature mischievous grin and big, expressive eyes. Her iconic pigtailed hair is dyed half pink and half blue, with streaks of glitter reflecting the light. She's holding a colorful spray-painted baseball bat over her shoulder, hinting at her unpredictable and dynamic personality. Around her, cartoon-style doodles of playful chaos like tiny bats, joker cards, and graffiti hearts add layers of fun and rebellion to the scene, capturing the essence of her wild and whimsical spirit.
