Since all the Arrowverse shows have their sort of "openings," I thought I'd do a take on them as the prologue. :)
"My name is Oliver Queen. After five years in hell, I returned with only one goal – to save my city. Five months ago, a man tried to ruin everything I had worked towards. He took everyone I loved and put them back in hell to try and make me suffer. I would have lost them if an ally I put all my trust into didn't save their lives. Three months later, it was my turn to return the favor. Today, I fight my war on two fronts. By day, I lead Star City as its mayor with the support of the girl I owe everything to. But by night, we are someone else. We are something else. I am the Green Arrow. She is Supergirl."
"My name is Kara Zor-El. I'm from Krypton. I'm a refugee on this planet. I was sent to Earth to protect my cousin, but my pod got knocked off course, and by the time I got here, my cousin had already grown up and become Superman. I hid who I really was until one day when an accident forced me to reveal myself to the world. To most people on this Earth, known in the multiverse as Earth-38, I'm a reporter at CatCo Worldwide Media. But in secret, I work with my adoptive sister for the D.E.O. to protect my city from alien life and anyone else that mean to cause it harm. On the Earth known as Earth-1, by day I support the man I love in his job as mayor and protect his son, as I know his mother would have wanted me to do. But by night, whenever he needs my help, I work with his team to save his city and ensure no poison ruins the work he has done. I am Supergirl. He is the Green Arrow."
A/N: They seemed fitting. :)
So this book will follow the current seasons of Arrow (S6) and Supergirl (S3) and will try to stay with the timeline. No promises that it won't be at least slightly wonky, because it more than likely will be, because . . . well, they're weird.
So, the Supergirl episode "Girl of Steel" will be first!
