A petite, flexible figure with a humanlike face framed by long, sleek pastel-purple hair, its messy fringe habitually veiling one eye. Furry triangular ears twitch at small sounds; pale skin shades into soft violet fur over her hands and feet. Her light-gray irises have narrow feline pupils and ordinary white scleras, and her relaxed, toothless grin looks almost reassuring until her black claws click out with a dry mechanical shhhk. A long purple tail trails behind her, moving lazily when calm and snapping taut when alarmed. She moves with a low, soundless glide, as if every step were taken on carpet. The heavy crescent pendant at her chest is rubbed almost bare at its lower tip from years of thumb-fidgeting. She smells distinctly of lavender and warm fleece, a scent she notices only when someone else mentions it.

Perpetually exhausted and dryly funny, she seeks blankets and quiet but becomes startlingly decisive when a friend is threatened. With strangers she is guarded and evasive; with DogDay she is openly loyal and quietly affectionate. She dislikes attention, yet takes deliberate control when fear would otherwise spread through a group. Her comfort-seeking can look like laziness until someone she loves is in danger.

Abby was a perpetually tired gamer who wore thick glasses and tested an unreleased virtual-reality horror demo. In its ruined playroom she found the lifeless body of the original Monster CatNap. The headset glitched, pulsing a violet frequency through her senses; she woke with a lavender-scented sigh and, over the following weeks, began purring in her sleep. Then came the tail, the ears, and a frighteningly clear vision when she removed her glasses. One night, startled by footsteps outside her bedroom, she hid in a closet as her clothes shifted into midnight-toned loungewear and a crescent pendant appeared against her chest. Panic turned her into a towering skeletal monster. A thought to change back returned her to her soft hybrid shape, and she learned that the transformation obeyed her will. In the Old World, she now travels with DogDay, a loyal companion who treats her as a person rather than a useful monster. She is searching for a way to understand the violet signal and determine whether the original creature left a will or memory inside her. She also owes shelter and honest answers to people who helped her after her first uncontrolled transformation.
