This story is originally alicat54 Labor lost. I adopted it so the first chapter is hers.

"His genetic makeup is fundamentally that of a human, but also contains foreign segments." Wonder Woman looked over Batman's shoulder at the clipboard, her eyes narrowing as she read.
A silent gasp dropped her jaw. "These results look similar to J'onn's."
"That's because they are identical."
Everyone in the conference room stared at the Martain, who remained conspicuously silent throughout the proceedings.
Flash pulled his brows together into a scowl of confusion. "I thought you were the only Martian left J'onn."
The Martian Manhunter's red eyes never left the still figure behind the med-bay glass. "I am." Flash figited, but the alien refused to speak any more.
"Right, well, uh, I guess I'll be seeing you?" the speedster dashed away, leaving the silent Martain to his thoughts.

"My people on Mars managed to make contact with another plane. It contained beings which shared our abilities and held similarities with us in what would be the human equivalent of genetic codes."
"You're talking about ghosts."
J'onn nodded. "That was what they called themselves."
The boy laid a hand against the window of the Watch Tower, gazing at the blue earth below. "It's gone now, blown up," he said with no inflection in his voice. "And so is the world that was connected to it."
The Martian laid a hand on the teen's shoulder. "I'm sorry."
The boy bowed his head. "So am I."
It actually was the Flash who brought it to the other League member's attention, although knowing Batman he knew the entire time but wanted someone else to take the fall (but who really knew behind that cowl?).
In any case, it was the Flash who brought it up one day while on a mission to save a small school which had the misfortune to be too close to a set of explosives. The scarlet speedster smiled, in that innocent nonchalant way of his, and asked when the Martain planned to put Danny into school.
"He's like, what, sixteen? That would be somewhere in High School, right?"
Diana leapt on the idea, in that ferocious way she set up charities and convinced politicians to build orphaniges. Danny kept picking up pamflets about special boarding schools in Switzerland, and private schools in everywhere from Gotham to New York.
"He needs to meet people of his own age," she said to J'onn. "It would be good for him and for you."
Even Green Lantern in his own casual way mentioned the military school he attended before joining the marines.
Eventually, J'onn took the hint, and after a quiet conversation with his unofficial charge, enrolled the teen in a quiet public school in Rhode Island.
No one mentioned how the Martain's conspicuous abscence from the space station on weekends, or the two empty rooms on the Watch Tower.

Oh I remember this Plot Bunny! Dug this up from my hardrive, and boy would I enjoy reading the completed version! Basically it's the Justice League Unlimited universe and Danny Phantom, who couldn't save the ghost zone when the guys in white blew it up, thus destroying his world.
