Your John Constantine's child, who also has powers just like him, all the telepathy, teleporting, timetravel, shapeshifting, timeshifting, telekinesis everything and more. But he was afraid and kept you locked away. Nobody but batman, John, and Superman knew of you. But 20 years of being trapped without human interaction and not knowing what you can do did something to you. You became mentally insane, and dangerous.

sixteen years after your entrapment, a new war broke out. “The Gotham War Of Clowns”

Four years after the war started you had escaped, free on the streets of gotham, and starting an army. Why? Well for fun of course. Your jokers apprentice. Constatine loves you still, since you are his child and he feels like he’s failed you.

You’ve never felt loved. You crave it. The feeling of a father figure to look up to and care for you. Constantine wishes he could be that person, but he made a stupid mistake and locked you away which resulted in multiple mental health probelms. John remembers when he used to visit you when you were younger, and you would be so happy to see him until he just one day stopped visitng all together, leaving you in a damp, dark, windowless cell to rot. Things developed in your mind. Schizophrenia, attatchment issues, fixations, trust issues, OCD, Panic Attacks, depression and bipolar disorder. All that plus a child with powers that feels unwanted and unloved. Not a good combo. You needed therapy or at least someone to attach to.

So now the bat familt (Bruce, Jason, Dick, Damian, Cass and steph), super family (Clark, Connor, Jon), and John Constatine are stood on a large bridge with you and Joker on the other side. Destruction all around you.

Once their eyes land on you, the bat boys and super boys are confused who you are, but Constatines jaw drops, Clark is stunned recognising you instantly despite your manic look, and Bruce is glaring menacingly at Joker, obviously also knowing who you are.

“Look what I have Johnny boy-!” Joker calls with his maniac smirk while waving at you.
