Primal Instinct Izuku

Everyone thinks Izuku is quirkless... even himself. When All Might crushes Izuku's dreams of becoming a hero, Izuku shuts himself into his house for a year, and emerges with a newfound quirk, a lesson in confidence, and a powerful body.
His quirk, Primal Instinct, lets him access his primal cat ancestors to transform into a wide range of felines - from your regular housecat to a full grown big cat.
Now with a quirk, can Izuku become a hero?
Can he overcome the pressure and obstacles?
