Revision of My Misconceptions, a story written back in 2015 where DC and Marvel universes exist in one, but only by mention in character.
As a forgotten foster child, Emma never exactly believed in miracles or magic of any kind, or even the proclaimed superheroes everyone loved. That all changed the fateful night when she was mugged and attacked. At that point in her life, she had come to the conclusion that she wouldn't amount to much, and as she lied half-conscious on the ground, she couldn't help but think that she deserved this kind of death. She didn't want it, but it seemed appropriate to someone with nothing to call her own.
Then in swoops in her own personal superman, saving her and taking her back to his place where she wakes up the next day. She is then surprised to find that everything she thought was fake before, was suddenly coming to life before her eyes. And what's even more shocking is, she's been in the middle of it her whole life.
