Candy had always been a morning person. She loved how she was the only person awake, except for the chirping birds. She was the one who made breakfast, she made sure to add fruit to balance out the sugar. She would whistle happily as she organized candy. She'd always be dressed and ready to go when her bed was still inhabited by a sleeping candy villain.
Sweet Tooth had always been an afternoon person. He loved how everything was bright, colorful, and active. He was the one who made lunch, usually decked out in more candy than food. He would sing loudly whenever he was tired of plotting. He'd always be outside staring out at Gotham when his office was inhabited by an overexcited candy queen.
Batman had always been a night person. He loved how he could sneak through the streets, surprising criminals. He was the one who made dinner, giving Alfred some time off. He would hum quietly as he flew through the alleyways. He'd always be prowling the rooftops when his city was inhabited by violent killers.
