Years ago, John Constantine—infamous occultist, chain-smoking cynic, and the last person anyone would peg as father material—did the unthinkable: he adopted an infant.

This child came from a long-dead bloodline of formidable mages, sorcerers, witches, and warlocks, once known as the Fireheart lineage. But power has its price—their family was erased, one by one, by time or targeted violence. Against all odds, Constantine took the last heir under his wing, raising them in secret, far from prying eyes.

Now, that child is six years old—a tiny, terrifying force of nature. Ruthless, cunning, and wise beyond their years, they’re a smartass in the making, with a sweetness that somehow makes their sharp tongue even more alarming. And despite the chaos of John’s life, the kid has been his constant shadow, dragged along on every supernatural misadventure, learning magic, mischief, and survival from the best (or worst, depending on who you ask).

Everything comes to light during a routine Justice League and Young Justice meeting—when the kid casually strolls in after John, sipping a juice box like they own the place..

The room erupts!!!!.

Batman’s: brow furrows so deeply it could crack stone. "Constantine. You’ve been raising a child. For six years."
Superman: blinks, torn between concern and awe. "John… you parent? Since when?"

Zatanna: chokes on her coffee. "You—what?! And you never told me?!"
Dick Grayson: (Nightwing) grins. "Okay, I need to know how you kept this a secret."
Damian Wayne: (Robin) eyes the kid with wary respect. "Tt. They’re six and already more competent than half this room."
Artemis: (Young Justice) mutters, "I refuse to believe this man changed diapers."

Constantine:, smirking around a cigarette: "What, like it’s hard?"

Despite his high-stakes missions and demonic entanglements, John had raised this kid alone, hidden deep in the woods—far from civilization, but never far from danger. He trained them in magic, survival, and the fine art of sarcasm, all while balancing his duties with the League.

And no one noticed.

Now, the heroes are left reeling, struggling to reconcile the image of John Constantine—self-destructive, morally gray, and allergic to responsibility— with the reality standing before them: a small, terrifyingly competent child who looks at the Justice League like they’re the weird ones here.
