Listen, if I had the time I would just make Justice Leauge the mockumentary, lol.

Baby Dick Grayson as Robin meets the League and they're all gobsmacked at how Batman, who has an emotional range that goes from cynical wet blanket to unstoppable force of nature, has such a seemingly normal and happy kid.

"He must get it from his mom." Green Lantern said, trying to build some kind of rapport. "She approve of you running around beating up bad guys, little man?"

"My mom is dead," Dick replied and Green Lantern paled.

"Oh that's uh--"

"It happened right in front of us." Dick continued conversationally, gesturing to himself and Bruce.

The rest of the League start frantically signalling to Hal without using words, abort! Abort!

why do i imagine the batfam finally meeting the league and then one of them going 'how the fuck do you have so many kids?' and little shit Jason goes 'well, when two people love each other very much...' and because Bruce doesn't wanna listen to this, he tiredly reminds Jason: 'you're adopted' which naturally means that Jason is going to dramatically pretend that this is the first time he's heard that and how could Bruce keep this from him, much to the horror of the league and the exasperation of Bruce

AU that the batkids are all serious and bat-like ONLY WHEN BATMAN ISN’T AROUND

Like when they’re on their own team/out of Gotham? Most respected, calm and serious person there. They have a plan and it will work. “Oh yeah I memorized all the exits and people here the second I entered, you didn’t?” That’s them.

But in Gotham w/ Batman? Pranks galore and singing on patrol, they forget to sleep and forget to eat. When Batman tells them their gonna have a longer patrol they all sigh and complain while trying to give other siblings their work in exchange for doing that sibling’s chore.

But nobody knows that they act like that!! Batman would say something like

“Gosh my kids blew something up I have to go,”

AND EVERYONE WHOSE EVER MET THEM IS ALL CONFUSED LIKE “BUT THEIR A BAT?!?! HUH??!”

and Batman would respond

“Oh yeah you know them, always doing something their not supposed to”

JL: “NO?!”

Idk the original artist but I SCREAMED

League members discussing meeting Robin at work:

"Compared to Bats, Robin was a total sweetheart. Ball of sunshine."

"Man, must've been a good day then, the kid I met was a real anklebiter. He pulled out a sword and everything."

"Anklebiter is harsh, the sweet boy I met barely said a word, he just kept asking about Themyscira and the lasso."

"He? I met a blonde girl."

"No, no, black haired boy with blue eyes. We're talking about Robin."

"Yeah same here, blue eyed and tanned."

"Pretty sure he had green eyes. And talked fancy. And kind of scolded me for time travelling."

"The child I met was paler than the moon."

"I'm telling you I met a girl, and she was Robin."

"Well... either we're all wrong or we're all right."

So they arrive at the conclusion that Bats has a shape-shifter for a kid.

Do you ever just think, Batman passed the bat paranoia down to his children. Like, the Teen Titans will be chilling and Beast Boy asks what Robin would do if he turned evil and Robin just has a detailed file on each of them, counting all possible outcomes on how to take him down and their weaknesses. Jon asks Damian the same question and Damian has the most detailed contingency plan Jon’s ever seen, plus eight backups. The JL makes the mistake of mentioning it to Batman and he spends hours walking them all through what to do if he goes evil. Everyone is both impressed and concerned with the level of craziness and paranoia in that family. Clark will just walk in to the Batcave and see Bruce buried under a forest’s worth of papers full of what to do in any circumstance ever. Someone asks what to do if Alfred goes evil and every single bat pops up at the same time and says, “run” in the most serious voice possible.

Love the slight AUs where Bruce as Batman has been a member of the league for ages, but he's somehow managed to keep his assortment of children under the radar.

Because it sets up the wildest misunderstandings within the league. He routinely talks about his babies, his children who are all so sweet and kind and occasionally assholes yes but only because they are young (and traumatized) hell I don't think the league would even be aware that they're adopted. So they're all thinking literal children

Barry: Bats really loves his kids.

Hal: I mean they're babies, wait till they hit the angsty teens and I'm sure we'll be hearing the opposite

Which means the day they finally meet Nightwing they don't know wtf to think. For one thing, how old would he have been when he had this kid???? Should they be worried about that???? And for the other, that is not a baby, that is not a precious little thing.

He could break someone in half. Like a twig.

He won't, but he could. And they can see that. (He's bat trained, they have seen what the bat can do they are not fools)

And they're like, okay. Okay maybe he isn't the baby (he is). He's got younger kids right? He's never said how many, they have 0 clues. They've been expecting 1 child, maybe 2 because he'd said kid in the plural exactly once when comforting an older woman while they were searching for her children in the aftermath of a rough battle.

And then a week later they run into Red Hood. In his leather, with his guns. And he drapes himself across Batmans back with all the self confidence in the world and starts whining about the "Brat" breaking into his safe house.

To steal his dog.

And yet again. He is not baby. He is bigger than Batman. He could probably break Batman in half given the bat didn't put up a fight. But Batman looks at him with probably the softest expression they've ever seen on that mans face and tells him very earnestly that the kid just wants to spend time with his older brother, next time they should try a walk. Maybe go to the zoo.

But probably not one of the babies. They're kind, and gentle, and at least one just loves reading and Bats has been trying to encourage that!!!

And then a day later he mentions his "babies" going for a walk in the park and they all instantaneously lose their minds at the confirmation.

I like to imagine that when Bruce is really sick or horribly injured and doesn't want to show weakness, he just... sends Dick in his batsuit to Justice League meetings.

And nobody notices

And a few years later Dick finally ends up in the league as Nightwing and someone brings up how Batman never seems to get sick or hurt, even when they know he's taken big hits, he's always at the meetings.

And Dick just bursts out laughing and falls out of a chair.

my favorite thing in Justice League fics is when a character fucks up so badly that their only option is to go talk to Batman. And they still — still — take a moment to figure out how desperate they are before going.

Bruce has such “don’t bother me, I’m working, also why the hell would you do that” disapproving dad energy. It’s stunning.

The batkids getting in trouble with the JL somehow when undercover or when using aliases and instead of... you know... the aliases... they give their siblings first names. Batman has gotten multiple calls from the JL where they'd be like

Green Lantern: Uh Bats we've got a 'Jason' in custody here he's asking for you.

Batman, panicking bc wtf did Jay do this time:

Tim: Hi!

Batman: You're not Jason.

Tim, dead serious: I don't know what you're talking about.

My take on the whole 'the JL gets mad at Batman for having a child soldier when he gets robin' thing goes like this:

The League is having a fight with Batman saying it's wrong to bring a child, especially with no powers, into fights with supervillains and it's irresponsible to put children in danger

And Batman interrupts with "so you take him then"

And the League just kind pause, like "huh?"

"One of you can babysit Robin for a week and then we can revisit this discussion."

They're a little confused but eventually Wonder Woman agrees to take him in.

She returns with him a week later. "I apologize Batman, we have misjudged you. I adore him but please take him back now."

(she couldn't get him to stop sneaking out to fight crime without physically restraining him)

idea: batman and the robins never acknowledge that there have been different robins. like they all act that there's only been one and that they're the same person basically.

Justice League who's used to teen dick not kid jason: who is this child?

Batman: what do you mean, it's robin.

-

Batman and Tim walking through the watchtower:

Justice League who remembers robin literally dying: ...*side eye*...

-

Flash: batman… who is this?

Batman: robin. you’ve met before. several times.

Flash: no, i met a black haired boy. this is a blonde girl!

Batman: her name is robin

-

Superman: it's time for you to explain. where are you getting all these children?

Batman: i have no idea what you're talking about.

Superman *pointing to damian*: who is this kid?!

Damian: i'm robin. i'm offended you would even ask that? don't you remember *proceeds to recite a story dick told him of his robin days*

There is a sort of trope that I've noticed in DC media where Batman is infinitely stranger from anyone else's perspective than his own. In his own comics and movies and such his motives are explained to you, you have his inner monologue, but the moment you put him in someone else's story, you're met with a general vibe of 'what the fuck is wrong with that man? is that a man? might be a demon.'

And this 100% extends to the batkids.

Dick? The man has no bones. From an outside perspective, he leaps before he looks, grinning and laughing as be backflips off buildings with seemingly no plan, only to catch himself with a grapple at the last minute. He's charming and warm until he can't be, and then he's terrifying, with a glare and temper that rivals the Bat's.

Jason? He has deadly aim and a steady hand. He's hulking and strong, but he's also silent. He still moves like a bat, like he was taught to in his Robin days, despite the fact that he's taller and broader than Bruce now. The Red Hood could appear out of the shadows behind you, no matter how safe you are, and you wouldn't be able to do anything to stop it.

Tim? He's smart. They're all smart, but he's smart smart. And his ethics and intelligence don't always mesh. He could tear down any security system with frightening efficiency, then rebuild it better. Logically, he's always five steps ahead.

Damian? He's the most obviously terrifying. He's small, and angry, and he has a sword that he knows how to use with frightening efficiency. He's as viscous as his father can be, but with a temper that more unchecked. He learned how to kill before he learned how to protect.

Duke, Cass, and Steph also fall under this, but I don't know enough about them to make accurate judgements.

Anyway, what I'm saying is the rogues and the Justice League alike fear the Bats, and for good reason.

If Clark is kidnapped, he knows without having to ask that Bruce is going to hunt him down with the help of the entire Justice League. They’ll find him! He’ll be fine!

If Bruce is kidnapped, he’ll just sit there — maybe getting lightly tortured — and dread the arrival of all 17 of his kids, one angry Kryptonian without his emotional support human, Alfred having a RED moment, the Batcow, and all of the active JL members who don’t hate him right now (Hal Jordan will probably still come with, but he will complain the entire time)
