Earth 23 (Re-editing process...)

Welcome to Earth 23.
Barry Allen is the son of Henry and Nora Allen, They attended a gala night by Mr. Bruce Wayne, when a trickster and Joker poisoned every woman in the gala and includes Nora. Henry was devastated when he got back from a call outside seeing his wife dead. Barry barely making friends with the children of other rich kids he saw from the kid's room window that the ambulance was there in the downstairs, curiously he went there and saw her mother lying on the ground as well as the other woman spitting blood everywhere. Good thing heroes brought justice on her death. They promise to her in every occasion they will come home to father's childhood home in Midvale as tradition continues.

Kara Zor-El has landed on Earth and ready for its first winter vacation. While she is warming up get used to living on earth like the other aliens and his cousin alike. Her family Danvers just received a bad news about Jeremiah, his adopted father was being abducted. Just like how she lost her parents on an explosion of planet. How her future as the crown princess of Krypton was gone in a second, she was about to rule the 14 planets and 27 diplomatic friendships in the other planets across their Raonian Solar System. She was enraged and scared once again, she tries to run off as ended up over the cliff being sent the way from a reality where only the Royal blood of Krypton can go. It was her ancestors the one who chosen in the past by the Rao's Tattoo that translates into "Fierce of the Justice" The Elders of the House of El including his father and Uncle Jor-El and the High Priest Council of Krypton where they are the one who leads the Empire when the chosen by Rao, dies.

All that changed when she met Barry Allen for the first time (like how little Lily and Severus meet in HP.)
Especially when she caught him flying above the cliff the one between Barry's father's old home and Kara's new home.
Will they be falling for each other or accept what's in front of them?
