The Back Story

“Hi baby” A woman said as she picked up a little baby. The baby was in a basket on her doorstep. This woman was already 7 months pregnant with her own child, but she could just leave or give the baby away. So, she took this baby in as her own kid. This baby was you, and this woman was Inko Midoriya. You have black h/l hair, Mid-night blue eyes and pale skin. Your real mother wanted you to be safe and away from your father at all costs. Your father was a villain, and your mother was also dying so that is why she gave you away. You were only 3 weeks old when Inko found you. Your birthday is May 15, and Izuku’s is July 15, so you are two months older than him. When Inko found you, your birth papers were in the basket with you. (Of course, you don’t know this yourself)

When you were 5 years old you got your quirks. The first quirk is called Neko, but you call it Beast sometimes. This quirk makes you super strong, very fast, gives you a great sense of smell and sight, you have supersonic hearing. It also gives you cat ears and a tail, so you can do anything a cat can do. When you get mad you can turn into a giant cat beast, and you don’t have any control over what you do when that happens. Your other quirk is that you are fireproof.

You and Izuku grew up with Katsuki Bakugo who you both call Kacchan. You and Kacchan were best friends and you guys did everything together, but that all changed when he got his quirk. He loved making fun of you and Izuku since you guys didn’t have a quirk. When you got your quirk, he only made fun of your brother. This pissed you off and you were always protecting your brother. You were now always yelling at Kacchan and you no longer wanted to be his friend.

One day you lost control of your quirk and you turned into a huge cat beast. You scared and almost hurt your brother and Kacchan. Kacchan and Izuku were both crying but kacchan was able to calm you down. You looked at them in fear and ran to your room crying. You knew you didn’t want to ever lose control again. But that was a long time ago.

You got into UA High School; you didn’t want to be a hero, but Izuku convinced you to go with him. You both got into Class 1-A. You knew that All Might gave Izuku One for All, you were just happy that he could now protect himself and become the hero he always wanted to be. Your now 16 and you also found out that you also have a healing quirk. Which comes in handy with your brother (:-)).
