A Chat among Bats (ML x DC)

Ladybug and Chat Noir manage to defeat Hawkmoth, unmasking him as Gabriel Agreste in the process.

Adrien does not react well to the realization that his father was the villain they’d been fighting all along. He’s Chat Noir, one of the heroes, he should have noticed. And the public suspicion on his civilian identity due to the familial connection does nothing to help that guilt

So he runs. No identity reveals with Ladybug (he doesn’t feel like he deserves one), no formal public goodbyes in his hero identity. Just… grabs a ticket and vanishes. Maybe leaves some notes at most. He had no idea where he’s going, but surely anywhere could be better than Paris.

He lives off of his savings and money from odd jobs as he wanders (and perhaps the occasional theft from criminals or the corrupt), eventually meandering path into the crime-ridden city of Gotham. There, his heroic instincts (plus the fact he still has the Black Cat Miraculous) lead to him taking up a new heroic identity, joining the ranks of the city’s vigilantes. And probably also causing Selina to fight Bruce over who gets to adopt him.

Marinette, unsurprisingly, took his vanishing poorly. She didn’t immediately know his secret identity, so from her perspective two of her favorite people just vanished at the same time. Learning that they are actually the same person maybe helps a little in that regard, but it also reinforces her thoughts that she failed him.

So of course she continues to look for him. She knows he probably wouldn’t want to return to the spotlight, but she still wants to help him out if she can. Or at least apologize for her (perceived) failure.

And thus, when she happened to recognize a certain individual in a news report from Gotham, she immediately booked the first flight she could. She needed to see him again.
