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?

Book 2 - Sequel to Primal Instinct Izuku If you have not read the first book, it is advised to do so. Midoriya Izuku was drowning. Sinking in a deep, black, inky liquid, that was so heavy and sluggish that it felt impossible to surface. He couldn't hear. He couldn't see. All he felt... was nothing. It was all black. . . . And then the world flipped inside out.

Izuku is quirkless. But with his father being the popular Pro Hero Flamethrower, Izuku didn't accept he was useless, but instead strove to embrace and overcome it. Izuku was taught to defend himself and was raised with skills. Since he was a genius, he skipped middle school and went straight to highschool, where he learned to be a Pro Hero by his father. At a still young age, Izuku became the first ever Quirkless Hero, and showed the world he was quirkless and powerful. How will Izuku impact the world, and the way that people viewed the quirkless? And how the quirkless viewed themselves?
