HI VEGA!! personally izuku being a bunny is my all time go to as far as making him a hybrid :D for katsuki, however…that just depends on what type of other au i’m going for, y’know? bc if it was a fantasy au, then a dragon most definitely (meaning: yes he can transform into a dragon, but his humanoid form still carrie’s dragon features). for a no quirks au, maybe a cat? other aus, i’d have him as a dog…and wild animals / reptiles are a whole new set of things to make katsuki LMAO but typically speaking, i’m always set on izuku being a bunny personally (MAYBE something else that’s cute too, idk i like making him a “prey” animal) but i like to change things around w/ katsuki (as long as it gets the point across that he’s a “predator” animal fitting the dynamic i want he and izuku to have)💗
