Summary
“Calm down,” Aizawa murmured, his voice low and soothing. “You’re safe here.”
'Safe?!' Izuku thought wildly, his ears flattening again as he stared up at the two pro heroes, who were now watching him with curiosity and concern. 'How am I supposed to be calm when I’m literally in the house of two pro heroes?!'
--
Izuku has a quirk that allows him to turn into a cat, but as of now...He's kind of stuck like this, like a cat, for /months/. It's fine, though, it means that now he can't be chased by Eraser-Head! After months of running away from that man, he would never suspect he was a cat! He thought he cheated the system, except that being a cat—a kitten—is harder than being a human. And so he got pretty roughed up when a rock was thrown at him, and many other things piled up the same way snow or trash piles up on the street.
After an altercation with a dog that left him on the brink of death, a cat dragged him to the house of a human
Out of all the faces on this planet, why Aizawa's? -

Summary
Quirk discrimination does not only apply to those who don't have one at all. In a world where a simple cat quirk cause Midoriya Izuku to be seen as weak and cutesy, he decides to prove to as many people as possible that he can be better than them all. Will he end up a hero who runs on spite and anger, a villain who thrives on it, or something right in the middle?
I orphaned this fic because I was embarrassed about how bad I believed my writing was. reading it back now, I think its salvageable and with time will reupload all thats written so far, write new chapters, and edit old ones! sorry to all my old readers, but I hope my writing is still liked!!
