It's an open secret of the Batfamily that Bruce's cape is a pocket dimension.
No one's really sure how it came to be. When Dick was starting to grow a little too tall for it to make sense to hide underneath his dad's cloak anymore, he noticed. For all his analytical mind and acute sense of detail, it seemed Bruce didn't know.
Dick didn't tell Jason, either. The boy found out eventually, and planned to keep quiet until the next holder of the mantel figured it out as well. It was almost a tried and true tradition of Robin's until a crowbar swung and broke those types of fantasies.
It was a quiet thing mentioned on late nights between the group after then. Everyone from Damian to Cullen knew, though on different levels.
Tim had tried to monitor it somehow, scientifically, or recreate it with various other capes and fabrics, but it never worked quite correctly.
When he mentioned it as a hypothetical to Zatanna, the magician just shrugged. "Something like that could be a gift from a thankful sorcerer or just something that just... poofs into being."
At some point, they'd devised a plan to see how many of them could find underneath the cape on patrol before Bruce noticed.
(Bruce, of course, had known since Dick. He always knew where his Robins were.)
Except all dimensions, even the pocket ones, are tied to the Infinite Realms.
Which Clockwork or any other older ghost probably should've explained to Danny.
It's a random Friday and he's in the Zone, floating around and in a group call with Sam and Tucker. His parents had gotten a lucky shot earlier that afternoon, so he's wrapping up his shoulder an ecto-soaked bandage when he comes across an odd looking door.
He's seen some weird ones before. One with a knob with as an actual eye, some glowing with various colors or smelling weird.
This one looks like someone draped black curtains onto a vaguely box shaped thing.
Curiosity killed the cat, but he's Schrödinger's, so ultimately after a vote between friends (2-1, Sam tells him Jazz would be ticked if he got hurt again today), he decides to see what's behind it.
Danny's kind of expecting some weird fabric world or just a black void.
But once he's floated into this pocket dimension, he can tell that it's almost like there's openings to the sides and bottom where the faintest of light is seen.
With the brilliance of a fourteen-year-old half-dead vigilante, he decides to pull it back and go intangible through whatever's in front of him.
...And proceeds to walk straight through Batman into a Justice League meeting, beaten and bloody with a makeshift bandage on his shoulder.
All Danny can say is "Heyy, guys, I'm gonna have to call you back..." through comms before all hell breaks loose.
AU where some new villain made a truth serum formula and captures Nightwing, Red Hood, Red Robin, and Robin. This villain somehow knows they’ve all been Robin at one point and decides to use the truth serum to try and drive a wedge between them all so that they stop working together. He starts with Robin, asking him who he thinks was the best Robin (Nightwing), who he thinks is the worst (Red Robin) and why he thinks that (Red Robin is annoying and arrogant). He does the same with Red Robin and Red Hood and gets varying answers that, while somewhat mean, are not enough to break the dynamic between them. Then he gets to Nightwing, who claims (truthfully) that he doesn’t have a favorite or least favorite Robin. The villain is displeased with this so they start to come up different questions to try and start an argument between the boys.
Eventually the villain asks “Which Robin is closest to the original? Closest to your Robin? Which one reminds you the most of yourself?”. Dick tries to fight the serum for a while, before finally biting out “The fourth one.” They all turn to look at Damian, and the villain scrunches up his brows, asking “Him? Really?” It was somewhat of a rhetorical question but Dick is forced to answer anyways. “No, not him. He’s the fifth Robin.” It takes a second before it clicks into place. “The girl Robin? Seriously?? I heard she didn’t even last a week!” Before anything else can be said, Batman busts into the villain’s lair and manages to take him down.
When they get back to the cave, the boys try to question Dick about it, slightly offended by the fact that he considered Stephanie’s Robin to be the most accurate to his. Dick, however, manages to evade them until the serum wears off. Dick himself isn’t quite sure how he can explain it to them. He’s not sure how to tell them that while he’s proud of all the work they’ve done as Robin, he never shared their reasoning for becoming Robin. He’s not sure how to point out the fact that the main reason they got into the vigilante game was for Bruce, not for themselves. He’s not sure how to explain that Robin might’ve been given to them for them to find light and happiness in, but that initially Robin was born from his darkness.
He’s not sure how to tell them that when Bruce told him about Steph, about Spoiler, about how she designed her own suit and went out to stop the man she has a vendetta against, he was so violently reminded of himself that he hung up immediately and didn’t speak to anyone for two days. He’s not sure how to tell them that when Bruce came calling a little while later, telling him about Steph being in-over her head, about him firing her, about her going off on her own only to end up tortured and dead, it was like staring in a mirror of his own relationship with Bruce, and that he’d punched Bruce so hard he’d nearly broken a finger. He’s not sure how to tell them about the quiet nights he stayed up talking with Steph, when Bruce was lost in time and it was just her, Damian, and Alfred around. He’s not sure how to tell them about how when Steph had told him about her relationship with Dean, he’d been reminded of his relationship with Liu so much he’d nearly thrown up. He’s not sure how to tell them that when Dick had opened up about his guilt about what happened in Blüd, Steph hadn’t given him any false placations, and talked about the guilt she felt over her role in the gang wars instead.
He’s not sure how to tell them that while all of them have felt like failures to Bruce, none of them had felt the harsh sting of Bruce ripping Robin away from them, the pain of Bruce telling them how incompetent and unworthy they were as Bruce fires them. He’s not sure how to tell them that while he may their older brother, he was only ever Bruce’s ward. Bruce never adopted him, and despite how far they’ve all come to work as a family, Dick still feels like an outsider sometimes. He knows Steph gets it. She feels like an outsider too.
"the robins are closer in age au" where none of them can pass as batman by themself yet.
bruce gets injured but batman was supposed to be somewhere so the robins just pile into the bat-cape in a stack and go by themselves. dick and jason are the legs, tim is the torso, damian sits on tim's shoulders to act as the face.
batman seems quieter and more... wiggly than usual, but otherwise no one suspects a thing.
Ok I've got a cute batfam idea and I wanted to share.
Bruce gets all of his kids earlier than cannon, but he only ever finds out about them in one specific park.
When he first went to that park as Bruce Wayne he saw a poster for Haley's circus, he decides to check it out one night, comes back with a child.
Of course at the moment this is nothing else but a tragedy, and Bruce forgets about the park.
But about a year or so later he is in that park again after chasing some criminals in there as Batman, after catching them and tying them up for the police he makes his way back to the batmobile to find three out of four wheels missing and one freaked the fuck out kid.
He takes him home.
After this Bruce takes a minute to realize it's the same park where he saw the poster but adds it all up to a coincidence.
Until another year or so he takes Dick and Jason to the same park for some family quality time, as the two boys chase each other around the playground Bruce notices a small little boy staring at him from behind a bench, he approaches the kid since he seems too young to be there all alone, when he asks where his parents are the kid simply answers "Egypt", when he asks if there's someone else looking after him he just shakes his head
Bruce takes another kid home that day.
Now Bruce is starting to notice a little bit of a pattern, but again chops it up to coincidences.
Until he's once again in the same park chasing after a possible drug deal happening there when he hears rustling in some bushes, deciding to investigate he finds a savage little girl holding a knife and covered with blood.
He cautiously takes her to the cave, but soon she's welcomed to the home.
Now Bruce is starting to notice something, he decides he needs to be a bit more careful whenever he end up in that park.
But then some months later the kids insist on going there to play in the playground, Bruce caves in and takes them over, not even 20 minutes in Tim and Cass come running towards him hand in hand with a little blonde girl wearing a purple hoodie.
He does not take her home with him, but that doesn't stop her from coming over every other day, and she's always welcome.
Bruce has of course at this point accepted that this park is blessed cursed, considering he got four and a half kids from it, he decides to try to evade it just in case he somehow get four and a half more.
That is until he gets a message from Talia asking him to meet up at that exact park, he sighs, leaves, comes back with a baby.
Bruce decides to evade that park as much as he can unless it's for an absolute emergency.
Until about 3 year later he has to go to the park for a fund raiser event, in which toddler Damian sneaks away for a good 30 minutes, frantically Bruce runs through the entire park just to find Damian playing ball with another older boy in a yellow shirt.
Much like Steph he does not take him home with him, but the kid is always welcome in the manors walls along with the rest of his children.
Bruce has no idea how or why all of his children essentially spawned in the same park, and he's kind of given up on evading it, in the future his kids might joke about the coincidences and claim the park as their "spawn point" but for now, as surprising and stressful as they were, Bruce is completely grateful and happy with all of his children that that park provided.
De aged Dick: I told you I didn't want little siblings! D:<
De aged Jason, crying under a table with a batarang: I DON'T WANNA BE KIDNAPPED!
De aged Tim, staring at Bruce with big, wide eyes: :o
De aged Stephanie, tackling Dick:
—
Bruce: Alright, until Zatanna can get here, you're gonna need to be on your best behavior.
Stephanie: I want my Mom!
Stephanie, kicking Bruce's shins:
Bruce: I am so glad you're not my kid.
Dick, staring at a Nintento game card: Why's the game cartridge so small!?
Bruce: Oh, yeah, I forgot you grew up in the 90's... Um...
Tim, trying to eat said game card:
Bruce: Timothy Jackson Drake, no!
Tim, dropping it quickly and posing like a startled Red Panda: :o
Alfred, holding Jason by the scruff: Sir, master Jason attempted escape again.
Jason: I'm telling my Dad on you! He'll beat you up! MY PARENTS ARE GONNA CALL THE COPS ON YOU! JUST YA WAIT, THEY'RE GONNA BE HERE AND TAKE ME AWAY FROM YOU FOREVER!
Bruce: Hrn, maybe I should've talked to Jason more about his birth parents when I got him...
Alfred: No Father is perfect, sir.
Stephanie: MY MOM SAYS EAT THE RICH!
Stephanie, taking a bite out of Bruce's hand:
—
Bruce: Look, I turned on a movie!
Dick: . . . Why is THE LION KING IN REAL LIFE!?
Bruce: It's live action—
Dick: KILL IT!
Tim, lifting a camera up slowly and snapping a picture of Bruce from a corner:
Bruce: !? Tim?! Where'd you get a camera!?
Tim, dropping to all fours and quietly crawling along the shadows to leave the room:
Bruce: . . . What?
Damian: Father, permission to be a tad bit suspicious of Tim's humanity?
Bruce: He didn't have any when I met him, now I think he might not be human.
—
Jason: I'M IN A BATMOBILE AND YOU'RE NOT!
Bruce, trying to open the door frantically: Jason Peter Todd get out of that car right this instance!
Jason: TAKE ME HOME!
Bruce: Jason, please, I'm not trying to kidnap you.
Jason: I WANT MY MOM!
Tim, popping up from the back seats to climb into the passenger seat and snap a photo of Bruce, desperately struggling to get inside the bat mobile:
Jason: WHERE'D YOU COME FROM!?
Tim, shrugging:
Jason: . . . YOU'RE WEIRD!
Dick, running around in Stephanie's Robin uniform: BATMAN, NANANANANANANA!!!
Stephanie, squealing as she swings Tim's bō staff around:
Damian, chasing after them both: ENOUGH, BOTH OF YOU! YOU ARE ACTING CHILDISH!
Jason, crying: I want my Mooooom.
Tim, turning on the radio, gasping when it works: :o
—
Dick, glaring at a laptop: That's not normal. Why'd you flatten the computer?! WHAT IS THAT THING ON IT!?
Bruce: It's a laptop, and that's internet, and I'm trying to contact Lucius to inform him neither Tim or I will be there for work today.
Damian: Must I go to school? This seems like a family emergency.
Dick: I don't wanna go to school either!
Tim, dropping from an air vent onto the floor, landing face first like a limp rag doll:
Bruce: OH MY GOD!?
Tim, coughing once before picking himself up and snapping a picture of Bruce:
Bruce: . . . I need to get Tim tested.
Damian: For?
Bruce, watching as Tim waddles away: Everything.
—
Stephanie: This place is to big, my Dad would never let me stay at a place this fancy.
Jason: We're being human trafficked!
Stephanie: I dunno, that guy hasn't tried anything.
Jason: Them why do you keep bitin' and kickin' 'im?
Stephanie: I just like to.
Tim:
Jason: WHERE DID YOU COME FROM!?
Tim, lifting up a blank, thick, white binder, flipping it open to reveal page after page of pictures of both Bruce and Batman, as well as Dick and Robin:
Stephanie: What's that?
Tim: Batman.
Jason: YOU CAN SPEAK!?
Tim: . . . Wanna hear me talk about Batman?
Stephanie:
Jason:
Both: Sure.
Tim, big gasp: :O
—
Dick, swinging from a chandelier, singing: WHO LET THE DOGS OUT!? WHO LET THE DOGS OUT!? WOOF WOOF WOOF!
Bruce, sipping from a mug of coffee: I'm glad I got those reinforced...
Tim, taking a picture:
Bruce: . . . Are you hungry?
Tim:
Bruce: You... You haven't eaten.
Tim:
Bruce: . . . Alfred, can you contact Cass? She might be able to communicate with Tim.
Alfred: Right away, sir.
—
Cass: Hi, Tim.
Tim:
Cass: What am I meant to do?
Bruce: Communicate with him..?
Cass: . . . How?
Bruce: You know body language better than I do.
Cass: He seems neutral.
Bruce: I don't think his facial expression has changed once.
Cass: What?
Bruce: Unless blinking counts.
Tim, looking at Bruce: I know what you are.
Tim, waddling off:
Cass: Why was he scarier as a child?
Bruce: The only one who wasn't terrifying as a child was Tim.
Jason, running through the halls with a bucket on his head, right into a wall: Oof!
Bruce: . . . And Jason.
—
Stephanie: You're pretty.
Cassandra: Thank you.
Stephanie: Why is there so many boys here?
Cassandra: Men usually have a harder time dealing with complex emotions and so are more likely to turn to violence to cope, hence why Bruce became Batman. As for Tim, Dick, and Jason? They ended up with Bruce and inherited his... Coping mechanisms.
Stephanie: . . . What?
Cassandra: . . . Want to go hang out at our girls only club?
Stephanie: YES!
—
Babs: Permission to ask?
Cass, braiding Stephanie's hair: No.
Stephanie, eating a king sized Hershey bar, looking like Kirby as she opens her mouth to consume it whole:
—
Bruce: Alright, I had to bribe Alfred with a months vacation, but...
Bruce, putting down two big bags of McDonald's:
Dick: MCDONALD'S!!!!
Tim, snapping a picture:
Jason: Is it drugged?
Bruce: No more than Gotham's food usually is. I got you a Wonder Woman toy.
Dick: I WANT SUPERMAN! :D
Bruce: You got Superman.
Jason: Hm . . . Bribe accepted, but only because if you try to hurt me I'm gonna tell the cops your Batman and get you arrested for forever.
Bruce, knowing damn well Jason hates the police and ain't no snitch: That's fine.
Jason, digging into a bag instantly:
Tim:
Bruce: Uh...
Bruce, slowly lifting a French fry between two fingers:
Tim, eating it from Bruce's fingers before waddling away:
Bruce: . . .
Dick: Wait, isn't that our neighbor?
Jason, lifting his toy in the air: WONDER WOMAN!!!
Dick: Wanna make her fight my Superman!?
Jason: HELL YEAH!
—
Bruce: Alright, Zatanna will be here in an hour. Thank god.
Dick: Is she gonna make us grown ups again?
Bruce: Yes.
Dick: YAY! NO MORE SCHOOL!
Jason: But I like school! Can I still go to school as a grown up?
Bruce: Uh... Of course, Jay, lad.
Jason: YES! EDUCATION! I can't wait to graduate again! :D
Bruce: uhhhh...
Tim: I ate the game card.
Jason:
Dick:
Bruce:

BONUS:
*Tim and Bernard, sitting in a hospital room*
Bernard: How'd you get a Stardew Valley Nintendo switch game stuck in your large intestine?
I love Joker Jr! And I am in love with the idea that in a Reverse Robin AU where the second Robin always dies, Tim — breaking through the brainwashing for just a second — turns the gun on himself to keep from killing Batman. And Bruce has to watch his son commit suicide in front of him to save Batman’s life.
And when Tim comes back (maybe Talia or Ra’s or Superboy Prime idk), he’s not mad at Bruce. If the pit exaggerates your strongest emotion: where Jason ran hot with rage, Tim runs cold with logic. Tim has always been more reserved and non-confrontational. So the Tim that comes back is cold and calculating and focused on revenge.
Tim understands why Batman can’t kill. Tim is an idealist. He believes in Batman and Robin and the symbols they represent. To kill for Tim would be irrational.
But he still wants his revenge, his vengeance. After all, Tim is already a killer, right? What’s a few more?
The plan started with taking out the Joker but grows to destroying all gas based villains (PTSD. He can’t feel safe with gas based villains running around. But he rationalizes it. Just because he’s “cold and rational” doesn’t mean he’s lost his emotions.)
Tim is smart. He never reveals himself.
He’s aware of the third Robin, Jason. Batman needs a Robin. That’s why, after Damien left to spread his wings, Tim bullied Bruce into mentoring him. The city needs Robin. So he’s glad there’s a new Robin. He loves all of the Robins. So he can’t let this one get hurt during his revenge. He needs to keep Robin safe and Batman and Damian distracted.
So he kidnaps Jason and keeps him in a massive underground bunker (a coffin) he built in the caves under Gotham, modeled after the mazes the LoA favor with moving walls and puzzles (because you have to keep little wings entertained and Tim will never have the chance to train Jason properly so he might as well while he has the chance). In the end, the only way out — the answer all the puzzles lead to — is there no way out so Jason has to dig his way out.
All the while, Tim has been manipulating Bruce and Damien into capturing all the gas based villains in Gotham and sticking them in Arkham via puzzles and clues Tim plants around the city. The villains include Joker, Poison Ivy, Scarecrow, Mr. freeze, etc. And when the rogues are all safely tucked away in the cells Tim has ensured they’d be places in, Tim blows Arkham off the map.
BOOM
Batman’s symbol is intact and Tim is avenged. Tim’s purpose on this earth is complete. He’s determined to slink back into his grave. There is no reason to keep sticking around. What’s one more death after all that carnage?
And it’s Jason — who discovered Tim’s identity during the weeks/months he was held captive — who chases after Tim with Damian’s help (Damian so guilt ridden and desperate to fix all the wrongs he got right with Jason.) They’re going to bring their wayward bird home whether or not Batman wants it.
