A DP x DC Crossover Prompt

No one remembers when the barrier began to crack. It started small — ghosts whispering in the corners of Gotham, strange lights over Blüdhaven, and the dead refusing to stay that way.

Then came the storms. Green lightning in the sky. Shadows that breathed. And a boy — glowing, quiet, carrying a crown made of starlight and sorrow.

“My name is Danny.”

He said it simply. No threats. No demands. Just truth.

“The balance between life and death is breaking. You’ve let too many live who should’ve passed… and too many die who still had light.”

Batman’s jaw tightened. Wonder Woman’s hand went to her sword. Constantine just muttered, “Bloody hell.”

The Justice League had faced gods, monsters, even time itself — but never something that was both alive and dead.

The Ghost King

Danny Phantom wasn’t supposed to exist in this world. But when the Infinite Realms began bleeding into reality, he came to fix what others couldn’t see. Because death isn’t evil. And life isn’t innocent. They’re partners. And he’s the balance between them.

Jason Todd felt it first — the pulse of something ancient inside him, whispering his second life wasn’t entirely his own. Zatanna saw her spells twist like vines around his energy. And Bruce, for the first time in years, didn’t know whether he was facing a child… or a god.

The Question

What happens when a being who understands both life and death decides the living world has gone too far?

What if mercy, not judgment, is the final reckoning?

Okay but seriously — how did we not get this crossover years ago? Danny Phantom x DC Comics feels like it was meant to happen. Half-ghost kid meets Gotham’s favorite collection of emotionally scarred vigilantes? That’s fanfic gold.

The Setup:

Danny Fenton, freshly crowned King of the Infinite Realms, accidentally (or maybe not so accidentally 👀) rips a hole between worlds — and ends up right in Gotham. Cue ghost alarms, panic in the Justice League, and Batman immediately trying to “contain” the new supernatural threat.

Except… Danny’s not exactly containable. You can’t lock up a guy who can phase through walls, vanish into shadows, and casually fly past your billion-dollar security systems.

The Gotham Reaction:

Batman: “He’s a metahuman. Possibly undead. Proceed with caution.”

Jason Todd: “Finally, someone who gets it.”

Constantine: “For the love of Hell, not another ghost king.”

Clark Kent: “Is he alive? …Do I need to call his parents?”

Danny: “So… do you guys also die on a weekly basis or is that just a me thing?”

The Chaos Begins:

Imagine Danny teaming up with the Batfam — Tim hacking ghost portals at 3AM, Damian trying (and failing) to stab a ghost, Dick just adopting Danny instantly, and Alfred somehow already making him ghost-safe tea.

The League’s losing their minds trying to classify him: Metahuman? Entity? Dimensional anomaly? Danny just wants to vibe and maybe prank Vlad by haunting the Watchtower.

Why Fans Love DPxDC

The Danny Phantom x DC crossover is one of Tumblr’s favorite fanfiction genres because it blends:

The supernatural humor and ghost-core aesthetic of Danny Phantom

The emotional depth and found-family chaos of the Batfam

And the infinite “what if” energy of cross-dimensional storytelling

It’s perfect for anyone who loves AU stories, ghost powers, vigilantes, and sarcastic teenage heroes who accidentally become cosmic royalty.

Fanfic Prompt (Feel Free to Steal)

“Gotham’s new ghost is protecting Crime Alley. Batman doesn’t know whether to thank him… or exorcise him.”

Reblog if you think Danny should join the Justice League Dark. Like if you’d die (literally) for a DPxDC animated special.
