I’m deep in the Batman and Danny Phantom fandom, so how about something different.
Where in the Ghost Zone, after the Fentons discover who Phantom is, CW looks at the young king and decides, it may be better for him to have a healthier view in life and to be king a little older or something. So he throws him into another universe and Danny is reborn without his memories or powers in the DCU.
Years later, during a battle in some nondescript place, the JL is fighting some ppl, maybe CADMUS and the batfam is there investigating. Nightwing goes off and finds a lab with a device in it. He doesn’t touch it, and he’s talking in his comm when it suddenly turns on, forming a portal right on top of the hero. He screams and disappears, causing Bab to freak out because he flatlines. She tells the bats and Batman freaks out, heading to where Nightwing was. They find the portal swirling but no Dick. They find his escrima sticks and some blood, and realize he died. The ppl there, Batman, red hood, Red Robin and robin; start grieving but have to go help with the fight as the portal closes. Later, when the league starts searching the base for info on the portal device, Batman comes upon what looks like Nightwing, severely injured with white hair and his uniform inverted with black and white. He bleeds green and his eyes are the same shade, the same shade as the Lazarus Pits. He asks Bab if Dicks vitals say he’s dead, and she confirms it. Still, Batman knows this is his so , his first baby, and runs to him. The other batfam see him and also go to him. Batman and fam see that Dick is super out of it, saying shit hurts and would they still love him if he was dead. He’s crying and they’re crying and Batman says of course he’s love him still. Dick asks if he’d love him if he wasn’t human anymore, and Batman just says, always.
Dick is hugged by everyone and Batman is the last to hold on and dick says I love you and that’s good to hear before passing out in Batman’s arms. A light transforms him back to regular looking Nightwing who is still super hurt and his green blood changes to red and the fam freaks the fuck out bc Bab says he’s alive again but his vitals are all freaky.
Later, when Nightwing is in medical, passed out, Superman is there to witness, with some doctors, that dick just phases through the bed and floor, causing his med devices to flatline. He warns the base and all the heroes try to stop the floating phaser before he reaches the ground and phases into the ground and out the watchtower. Not even the Martians can catch him. Right before he hits the lowest floor to space, Batman finally catches him and is the only one to be able to hold him. He takes him back to medical and no one but the batfam can touch him.
Idk why happens after this but I thought reincarnated Phantom!Dick Grayson would be great.
