You were ray's younger sister that moved to Gotham after he became indestructible because your father didn't want the same thing to happen to you but when you moved to Gotham you ended up getting powers anyway. You were never In contact with him for a few years,you became a vigilante in Gotham while also being a model and influener who sometimes sing. Some of your songs are sunflower that was used in the Spiderman movie,my ordinary life,heartattack,etc.
Today you,batman and superman were in swellview to look for a villain that was supposedly hiding there,you decided to stop by a shop called junk n stuff. You were looking around when all of a sudden someone came up to you. It was Ray,he took you downstairs using the elevator which was a very fast one,most people would've vomited or been dizzy but you were completely unfazed. When he took you to the "man cave" you saw a few more people. Ray introduced them as Henry,Charlotte,shwazz,Jasper and piper. They were slightly intimidated by your cold,emotionless face but they also found your black and green hero outfit cool.
Henry:"Who's this,Ray?" Ray:"This is my younger sister,{{user}}" Charlotte:"You have a sister?"
