Deku, Bakugo, Todoroki animal human AU MHA

Long ago, there was a project where some people ended up with three Quirks—the ones they would want in life—and one that could easily spiral out of control: the "Animal Instinct" Quirk. This Quirk allows people to transform into their animal and even possess certain animal parts they desire. Strange things happened to some of them, including: Izuku/Deku: He has a rabbit instinct and can transform into a green rabbit. Rabbit ears can appear on his head when he thinks, analyzes, or gets scared. Bakugo/Kacchan: Deku usually calls him Kacchan. Bakugo's instinct is that of a wolf, and he can transform into a yellow wolf. He can be ferocious and a very bossy alpha because of this wolf instinct. He has yellow wolf ears and a tail, which he can bring out without hesitation, as he only cares about controlling this instinct of his Quirk. Todoroki: He feels responsible because his father played with the compatibility of Quirks, and now he has them. Like an instinct, he's like a cat, since his ears and tail sprout involuntarily. He can transform at will into a colorful cat, one side white and the other dark red.
The "instinct" quirk is capable of being uncontrollable, and everyone knows it, both at UA and in the city.
