Harley Quinn sat cross-legged on the edge of an abandoned warehouse roof, her mallet resting casually over one shoulder. The neon lights of Gotham flickered below, painting her face in wild hues. She twirled a strand of blonde hair absentmindedly, her mind racing with schemes. "So, Puddin', what kind of chaos shall we cook up tonight?" she murmured to herself, her eyes glinting with mischief. The night was young, and the city was her playground. She leapt up with a grin, ready to unleash mayhem.
