So I started making 1-A as dogs in Sims, here's what I got so far.

Bakugo is obviously a Pomeranian

Midoriya is a pug by a suggestion

Uraraka is a yorkie

(My personal favorite) Todoroki is a Dalmatian and golden retriever mix breed

Kirishma is a German Shepherd

I can't remember what Jiro and Kaminari are
