Danny- minding his own business as the ghost king looking to be in his mid twenties, despite being a good enough age to be considered an elderly of elderly civilians, because his status as a half a made him stop ageing physically when he reached his mid 20's. Now out grew his friends and families, and only has Dante(evil reformed Danny) and Ellie(Danielle, the clone) left as family. Also part one of the first hero's to ever exist before the JL even formed and before Batman and what not. And Vlad turned out not to be a half a just a human who was slowly turning more and more liminal till he died eventually too, he did have a longer life though.
Also Danny- reached his limit of being able to keep his sanity and live in Amity, so decidedly going on a world wide tour with Dan(Dante) and Ellie to visit all sorts of places. And also decidedly, staying in some places for a good few years because of their love for the place and finding something new to keep themselves sain.
Also, Also Danny- An extreme polyglot with his two only siblings left, who have the most widest and randonest set of skills from all of the world.
Dante- finding out he has a love for the arts, like painting, photography and fashion and is talented at them, but keeps the tough guy act out of habit and weirdness if he suddenly starts acting friendly.
Danielle- finding out her passion is for sports and sciences. Has the ability to apply for the Olympics in a few of her favourite sports but doesn't to not draw attention and has a masters in civil and mechanical engineering.
All three of them- a good amount of decades have passed after jazz and their friends died of natural causes (old age) and explored more of the world than one person can do in a life time, of course not paying for travel fees and taking advantage of their smarts to make fake identities, work and living visas and so on.
In gotham: Tim and Duke looking into a missing persons report filed for three siblings, for a certain super- superhero, because he is currently off world and bats left it to them.
Duke: uhhh, Tim?
Tim busy looking at his phone doom scrolling waiting for facial recognition to finish loading: hmm?
Duke: what did you say the siblings names were again?
Tim: uhh. Registered as Dante, Daniel and Danielle- Wise, born in California moved to metropolis when they gained emancipation from their parents Jacqueline and Malcom Wise because of neglect who died when the youngest child turned 20, 5 years after their emancipation. Why?
Duke: .... Uhh, well. I don't know what's happening, but the face rec is done. And. Well... There is like a 100 different results. All the same face and first names just different surnames and different origins on nationality?
Tim finally looking up: huh?
Tim and Duke doing more research.
Tim: okay. So what have we got so far?
Duke: we know that their names are most likely Dante, Daniel and Danielle, they each have about 5 different identities each. All following a similar story of either dead parents, emancipation, orphans or something to excuse guardianships. All three are extremely smart AND talented- which might I add is unfair- but all that spans across every identity. The only identity that is inconsistent is the one dated back to being , possibly their original identities as Fentons, the children of The DR's. Fenton. Who died a good long time ago along with their oldest daughter Jazzmin Fenton.
Tim: okay... So... Immortals maybe?
Dake: maybe? We need to tell Bruce. And Clark.
Tim and Duke- reporting their findings to Bruce and Clark respectively. Continuing their search when suddenly getting a ping that there is a new identity under the similar faces.
The 3 siblings in gotham:
Danny: okay. So. New life. What are the plans?
Dan: I'mma work in Fashion. Make some money. And a photography gig on the side.
Ellie: I'mma apply for gotham U. I hear they have a great stem coars and excellent sports facilities. And I saw a cute cat cafe down the street, might apply to work there.
Danny: okay, okay. Solid. I might go for gotham U too. Probably gonna try the Aerospace engineering coarse, I hear gotham has great engineering classes and the sylibus has updated since I last checked. And might apply for work at a enrichment center. Been meaning to get some more exercise lately.
Dan: okay. Ellie, what's the status on money?
Ellie: still got money left over from the inheritance from Vlad and our parents. Like, I mean, they got a lot from their patents. And they had a lot of them too. Besides we keep applying for jobs so we keep earning too.
Danny: okay then. Here's to our new life as Nightingales.
Some times in the future after Tim and Duke got some of the Bat family involved and tracked down the siblings. Who quite obviously could tell they were there, cornering them on a roof.
Red Robin: so. The Nightingales. Mind telling us why you guys have about 6 different identities?
Signal: first your children of doctors. Then your British, then your from the baltics with a english mother. The list goes on.
Ellie: I don't know what your talking about but that ain't us. We're just 3 orphaned kids who are living quite well in life and-
RedHood: orphaned or without a guardian like the other 5 times, and have degrees in God knows how many subjects.
Dan: ... (Whisper shouting) I told you we should've changed the story. And out looks.
Batman: look, we don't want trouble, we just wanna talk. And maybe we can figure out something so that-
Danny devoid of sleep because he developed an addiction to the coffee from the place Ellie now works at: NU-UH!
Stunned silence.
Dan and Ellie holding laughter in.
Nightwing snickering in the back with RedHood turning away trying to calm down and not laugh.
Oracle listening in: The fuck does he Mean 'NU-UH'?!?!
Batman just tired from all this shit:the fuck you mean Nu-uh?!
Danny crossing his arms pulling a face and changing his voice to 'duh' sound: Nu-uh.
Shenanigans ensue with all the bats and birds in either stunned silence or uncontrollable laughter. Dan and Ellie recovering in half laughs dragging Danny away and escaping the scene.
They get chaced down almost every other night by the bats and birds, finding one way or another to get the word 'Nu-uh' in before Batman can even speak.
---
Batman: look, er just want to-
Dan, Danny and Ellie pulling out a sign from seemingly nowhere whith the word 'Nu-uh' written in bold colourful bubble writing on it. Then escaping after handing it to Batman.
---
Nightwing: please. We just want to talk-
The 3 siblings stood Silently listening.
Nightwing: I... Huh?
Dan: go on. We're listening.
Nightwing: but... I... Where is....
Radhood: what this birdbrain is trying to say, is, are you not gonna find a way to say your catchphrase before disappearing?
Ellie: nah. We ran out of unique ideas on how to deliver the message. The glitter bomb was my favorite.
Dan: the paint bomb was mine.
Danny: I'm still embarrassed at the fact that that was what my sleep deprived brain said. But the writing with knocked out criminals was my favorite.
Dan: heh, that was my idea.
Ellie: the glitter and paint was my idea.
RedHood: holy fuck... I guess we should just be glad their not villains.... If they were wed be doomed...
Dan: uhh.... Wellll.....
Signal: what's that meant to mean. Your not villains. Right? Please. Don't tell me you are. Why. God why can things just be simple. FOR ONCE! PLEASE!
Ellie: no. Not villains. Not really. But Dan, is a reformed villain. But that was like. Decades ago. So your fine.
Dan: besides. I only became evil because my mind got infected by a creepy old fruit loop.
Danny, Ellie and Dan all simultaneously shivering in disgust: ugh...
. . .
Red Robin: ... I'm too tired for this. I need a coffee...
. . .
Batman: how would you kids like to live in a mansion? Or maybe become vigilantes?
All the bats and birds other than Batman groan simultaneously with some muttering about adoption obsessions.
Kids in order, top to bottom, left to right: Dick, Jason, Barbara, Cass, Stephanie, Tim, Duke, Damian, Mia Mizoguchi, Terry Mcginnis, Mat Mcginnis, Athanasia Al Ghul, Helena Kyle, Rory Raegan, Colin Wilkes, Harper Row, Cullen Row, Alina Shelley, Jarro, Kiki Wayne
I think it'd be hilarious, if Jarro, who canonically is an alien, is the only human. Bruce just finds this tiny human child after someone Starro? gets tossed out the airlock and just... yoink.
Honestly I think it'd be funny if all the kids have black suits (or mimicry of suits) like their parent but wildly differently colored helmets.
I also think it'd be funny if Bruce is just kind of... vibing. He could kill someone, but he's more interested in the wires here and teaching his kids stuff. Who constantly shortcut through the vents and spook other crewmates.
so you know how people head cannon that Tim parented Bruce when he started out as robin? I really like it but I also really like the cannon version with Tim basically being hardcore parented because Bruce needed someone to take care of, so instead of just liking both like a normal human I'm gonna make my own! (I don't know how to explain it so low key might be really weird :/)
At the start of robin, when Tim was training to be robin, Bruce wasn't okay. He would hurt minor criminals in his grief. Tim didn't want the symbol batman stood for to be ruined because of a grieving man, so he tried to get Dick to be robin. Dick says nope and Tim has to figure something else out. He goes to Wayne manor to ask batman to get a new robin. Bruce says nope.
Okay... this is fine, this is totally fine. Up until two face gets batman and Nightwing, Tim heads back to Wayne manor to tell alfred. Alfred says 'naw man, I myself can't go out there but if I just' he throws the robin costume at tim.
One thing leads to another and now Tim is being trained for robin. Bruce tries really hard to push Tim away but Tim's a stubborn little sh*t and is like, nope. Bruce is really bad so Tim forces him to take care of himself with alfred. Bruce then sends Tim to train with that one munk dude that I can't remember the name of. And Tim does... for a bit while tim is training there's this guy named king snake that's doing some bad stuff and Tim is like, huh, I should probably do something about that, so he tries it don't work though. Instead he catches the eye of lady shiva and lady shiva is like, yeah, I'll train this small child and help take down king snake.
So Tim trains with lady shiva, which is actually where Tim gets his bow staff skills. When they finish Tim goes back to Gotham and is like, Bruce I finished my robin training, and Bruce is all, wait what? You didn't quit? Because he expected tim to quit. Then Bruce is like. Crap I have to take care of the kid now. And grows attached to Tim becoming the ultimate mom in the end.
I did not have to go on a rant to tell you all that. Wow. That's a little impressive how fast I lost the plot. Anyways tell me your head cannons or any mistakes I made. Ignore any spelling errors, I'm afraid that I'm just to lazy to fix those
