Summary
It starts slowly, the steady disconnect between who he is and who he should be. The man in the mirror becomes a stranger to him; he looks into the glass and wonders how everything became so distorted and backward and...wrong. He notices in bursts: when Teddy grows taller than him, when he’s kissing Ginny on her lips and looking at the subtle smile lines she’s starting to develop around her plush mouth. She’s got the cutest crinkles by her eyes.
His face is smooth as it was when he was seventeen. Which was 18 years ago. He hasn’t aged a day.

Summary
"He's the keeper of balance. Controls every portal 'n' every connection to any other plane of existence, or dimension or all that. Looks like he's nothing more than an ankle-biter, but that dodgy bloke's one of em Ancients. Can't get much more powerful than those, I tell ya, and most of em are proper pricks. Not really someone you'd want to par off to. Not even I'd try to mug one of those off." Constantine looked back at them, something really uncomfortable in his eyes. "So if that's really him? Yeah, mate, I'd say it's a bloody big deal."
Or: The Justice League finds records of something unsettling. And if they're right, things might turn out pretty bad for the living plane.

Summary
Nanjo Kojiro never expected to have any kids (and no, the three from S don't count) and was perfectly fine with that. He had his friends, his restaurant, and S. But then, he met Natsume Takashi. Kojiro has no idea what's he doing, but he does know one thing: he would give Natsume a home, no matter what it took.

Summary
Danny Fenton is not okay. TM.
Honestly? Just overall bad vibes.
But he's doing his best. Making it work. And trying not to become fully dead in the process.The Justice League is very concerned. But it's actually their fault they got involved so take that one, Batman.
John Constantine told them not to do the thing. They did it anyway.Or, Danny gets summoned by the League, and he actually kind of adopts them in the process. Because these big city heroes don't know anything about ghosts and who is he if he doesn't help them out? Besides, the Watchtower is in space. Danny's always wanted to go to space...
(I'm not really following any specific JL timeline, so like. Be prepared for 98% of everything to be *made up* and possibly *not real*.)
