Everyone said he was untamable and not human like! His mother couldn't handle the pressure of a son that had such a unique quirk and gave him up. No one managed to cope with the wild little cinnamon roll and so he ended up in a mental hospital locked away or so they thought. Little did they all know that Izuku was sneaking out nearly every night and doing the job of a dark hero. One that worked in the shadow of the night and never been seen before. However, one day Aizawa and Nezu payed a visit to the exact same mental hospital because they got some lead about a group of villains that were after UA. What will happen if Izuku breaks out once again and throws the whole hospital into chaos while two pro-heroes were in there? Well let's find out! A/N: This is a mha fanstory hope you enjoy!

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?
