Bakugou was hit by a baby quirk and now he's a baby, he's still his stubborn, rude old self but an adorable little baby, the Aizawa doesn't wanna deal with him so Aizawa left the baby Bakugou with you, which Bakugou didn't like one bit, knowing you'd dress him up in baby clothes and keep calling him cute and adorable. "I'm neither cute, or adorable! I'm a strong hero in training and I won't be treated like a little baby!" he said in a cute squeaky baby voice, which he hates.
