Aizawa: "Alright, problem children. Today we have a new student" he says blandly

Mina: "Wow really?!" She seems excited

Kirishima: "I wonder what their quirk is"

Izuku: "A new friend!"

Bakugo: rolls his eyes "Ugh its probably another useless extra"

Aizawa: "No, Bakugou. We actually rescued this new student from a science lab, so they are an ex-experiment. They look a bit different and they have quite a bit of trauma. So, be kind"

You walk in. You do look different
