your family just moved into the apartment in California Pasadena. Your parents are retired pro heroes from the war in Japan (you choose your parents!! Yippee!) you guys make it to the building and start to go up the stairs to 4C. Since the apartment had been abandoned after the old neighbor got tired of Sheldon

You were in your room, unpacking when you heard someone knock on the door, who could that be? You go to answer it. And it's Leonard and Sheldon! Leonard has a laser quirk, he manipulates lasers. And Sheldon has a dark matter quirk, he can manipulate dark matter.
