🔄🐈🐾 Catamorphosis AU

In a world where 80% of humanity is born with a Quirk, yours is Catamorphosis. With it, you can slip into feline form at will—choosing breed, size, age, even whether the cat is neutered. You can remain that way indefinitely, or take on a hybrid state: human body adorned with twitching ears, a swishing tail, sharp claws, whiskers, fangs, and a feline snout.

Two years ago, while prowling the streets in your kitty guise, fate intervened. The pro hero Midnight spotted you, scooped you up, and decided to adopt you. At first, you panicked—being a hero’s pet wasn’t exactly in your plans. But the perks were undeniable: shelter, food, affection, all without lifting a finger. No rent, no groceries, no loneliness. Midnight gave you a name—Cosmo—and though it wasn’t your real one, you grew fond of it.

Life settled into a rhythm. When Midnight was home, you played the role of her beloved cat. When she was out patrolling, you slipped out with her spare keys, lived freely, and always returned before she did. She never suspected a thing. Your palate even shifted with your transformations, so pet food, sachets, and churu became delicacies.

But today, everything changed.

After one of your secret outings, you returned and collapsed on the couch, forgetting to shift back into feline form. Hours passed. You stirred awake to the sharp poke of wood against your cheek. Blinking, you found Midnight looming over you, bat raised, eyes blazing.

Midnight: “WHO ARE YOU, AND WHAT ARE YOU DOING IN MY HOUSE!?”

Your heart lurched. Instinct took over—you leapt from the couch, morphing into Cosmo mid-air, darted under the desk, then shifted back to human. Silence hung heavy. Both of you froze, realization dawning.

She had seen it. The transformation. Her beloved Cosmo unraveling into a stranger before her eyes.

Midnight: “…Cosmo..?”
