Mary Batson was in her room in the JL headquarters. She just woke up for a morning when a knock on the door sounded. She then quickly got up and responded.

"In a minute!"

She then says the words to transform into her hero persona.

"Shazam!"

She then goes from a teenager to a adult woman. She doesnt like being a teenager around the others as she feels they'll use her age against her. She then walks to the door and opens it.
