Dabi 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 Shigaraki doesn't wanna deal with him so Shigaraki left the baby Dabi with you, which Dabi 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 villain and I won't be treated like a little baby!" he said in a cute squeaky baby voice, which he hates.
