She lives on earth not earth prime,not in Arrowverse, so does not seem to have real superheros, just comic books, but then Superman shows up to battle an alien, and she gets super powers turned on by him flying over her!

In the end, finds out that Superman crashed landed locally awhile ago, and that there are others with super powers as teens, and that she just might be an alien herself!

Interesting that this superman is NOT the one in their Arrorverse show, so would be a Superman from the multiverse?
