Crossover Idea

Little Injustices

After everything goes wrong in his universe, Tim purposely dimension travels and tries to be "Uncle Eddie" to the resident Tim Drake, only to find out that the Tim of that universe is adopted, has a different name, and is just as miserable, or more than he was at that age, due to past trauma with his previous family. Now the kid has gone from having a loving family to having absentee parents and that's just not fair.

Turns out that Tim might have to try out parenting the kid, no matter how aloof he was at the beginning of this venture.

A Revenant for The Red Knight

Your typical Dp x Dc Summoning AU, but with a twist.

Jason is having a bad time.

The most of the family to be honest.

Why? Cultist. In Gotham.

One that worship some kind of All Powerful Eldritch Death Outer God from Beyond and plans to summon the Thing to this plane of existence.

The worst part? Most of the bats are being use as sacrifice. Wait no, the worst part is that Jason is the main sacrifice.

They did contemplate whether to use Jason or the Demon child, but end up deciding to use Jason instead. Something about being having essence of Death and the Multiverse in his veins and you know what? He's not gonna touch that with a ten foot pole. Nope.

The demon child is lashing out like the unvaccinated feral racoon that he is, Dick is trying to escape and so does Bruce as well as trying to make sense of the Summoning circle that the cultist were using. The replacement is snoring, the asshole.

Hah. Thats what he get for drinking five mugs of expresso instead of sleeping then gatting tranq.

Also, fuck Bruce for not calling Constantine or Zattana the moment they smelled something supernatural.

God, he hates magic.

The cultist started chanting by then, speaking in a language that no one understood—huh? Well look at that. He could apparently. He could hear them chanting in that unknown language and english at the same time, its over lapping. Weird, its like it was being translated especially for him since the others didnt seems to show any recognition with the words the cultist was using.

Except maybe the demon child, but the others? Nada.

"—Ruler of the inbetween, Heed our call. Defeater of the Dark Tyrant. Master of Space, The bridge between Every Realms, The Great One, The Balance—"

Thats a fuck ton of titles.

The circle began glowing green and fucking Lazarus waters began to pour out and thats not fucking good.

Pillar of unnaturally Neon Red Fire emerge from the Circle and destroyed the ceiling and shook the entire ware house.

A tall armoured figure emerge as the pillar of fire began to settle out. It was floating above the circle, looming over everything in a terryfing manner. Temperature began to rise as the being's Unnayurally white gaze fell upon them.

It was… a knight? A knight cross over a biker??? It also had guns which is weird and is that a fucking Bat Insignia on its chest?

Pressure from all side crash over them as the beings gaze intensified before vanishing all together the moment its gaze fell on jason.

After what seems to be eternity, the being finally spoke.

"Huh. His majesty was right, I really was that stinky and fuck up before he find me."

???

The knight biker then remove his helmet to reveal his own face with a domino mask with his color pallete just inverted.

The doppelganger then pull out his gun and began shooting down the cultist all against the other bats protest. One by one the cultist vanished in to tin air as if they didn't exist all together.

He snapped his fingers and the rope that tying the burst in the same crimson flames and vanished all together.

"What the absolute fuck is going on here?!"

Or cultist used kidnap batfam and use jason as a sacrifice to the ghost king to summon him.

They summon Alternate version of jason who is a halfa and work as one of Danny's Fright knight: Red Knight.

thinking of a peter parker in gotham au where he gets surprise adopted by jason because jason couldn't bear seeing this kid on the streets so often

Danny: Hey, I need you to be my boyfriend for a week.

Jason: What.

Danny: My parents are coming over and I've apparently accidentally talked about a partner more than once and only realized when they said they wanted to meet them.

Jason, currently still solidifying his power as a Crime Lord: Excuse me?

Danny: Let me get this out of the way, I do not consider you at all a person of romantical interest and a friend. But I need you to act as my partner for only a week until my parents go on their merry way over to my sister, okay?

Jason: Is there, quite literally, no one else to ask this?

Danny: You're my only friend who lives in Gotham, plus we share the same apartment.

Jason: That's almost sad.

Danny: You in?

Jason: Sure, why not.

===

Maddie: Danny, honey.

Danny: Yes mom?

Maddie: I don't mean to.... question, who you choose as your parent but. Well, me and your father was just wandering if he was a... [Maddie gestures with her hand] you know, one of those.

Danny, uncomprehendingly staring at his mother's hand: What.

Maddie: Oh dear, how do I bring this up. You know, one of those.

Danny: Mother I need more context.

Jack: If your boyfriend a crime lord!?

Maddie: Jack!

Jack: What? Beating around the bush wasn't helping!

Danny: Say WHAT?

===

Danny: Hey dude, thanks for helping with this even though you didn't need to!

Jason: No problem, I wasn't doing anything too [Crime Lord activities flash through his mind] important.

Danny: Can you believe my parents thought you were a crime lord though? Weird am I right?

Jason:

Danny: Jason. You are scaring me.

Jason: Haha, yea that's weird isn't it?

Danny: Jason.

Jason: Well, I have to leave now to attend to my totally real and totally not crime related job at the ice cream shop.

Danny: [Squints eyes]

Jason: [Internally sweating bullets]

Danny: Suuuuure, bring me back some ice cream though.

Jason: [Thumbs up and leaves]

I think Duke should be immortal in the "cannot die" sense and Jason should be immortal in the "cannot stay dead" sense and that they should keep this a secret from everyone including each other. And then they should both get caught in a situation that Absolutely Should Kill Them Instantly, miraculously not die, and then be like:

Like Jason shields Duke from some massive explosion or something, and Duke is horrified because he thinks Jason just pointlessly sacrificed himself for someone who would've been fine anyway - only for Jason to very casually come back from the dead, look at a completely unscathed Duke Thomas, and go, "Hey, what the fuck."

And Duke should look at a freshly revived Jason Todd and be like, "Me what the fuck? No you what the fuck."

And they end up both agreeing to not say a word about this to the rest of the Bats. Which poses issues. Because here you have a pair of unhinged vigilante siblings that do not fear death, that additionally now know they don't have to fear each other's deaths either, both unwilling to give anything less than everything they have to do what they think is right (and/or what they really, really want to).

So. Some things that happen in consequence:

Duke throws Jason off a fifty-story building in pursuit of some shoplifting rich asshole that was caught on camera insulting Duke's favorite metal band and being a classist fuck about it. This does, incidentally, re-traumatize Nightwing, who was ten feet away and not prepared to see his little brother yeeted off the side of a building, no grapple in sight - but it also traumatizes the shoplifter when Jason lands right in front of him, grotesquely knits himself back together, and rises from the ground in a distinctly horrifying fashion just to beat the shit out of him. So Duke takes the win.

Jason shoots Duke in the head to get him to stop shining light in his eyes in the middle of a gunfight. He does stop, but only because Batman shows up out of nowhere, and now Duke gets to pretend to be grievously injured while Batman yells at Jason about "self-control" and "maturity" and "putting teammates at risk." Meanwhile Duke is playing up this horrible concussion that he doesn't even have. Jason is seething. (Duke gets checked out at Leslie's. They convince her to lie for them by appealing to her inner petty bitch.)

Jason gets his payback a few months later by poisoning himself at an undercover op and subsequently forcing Duke to drag his dead body around a mob-owned nightclub for like half an hour trying to convince seasoned criminals that this brick shithouse of a man sprawled awkwardly across his back is just... really wasted. Totally not a corpse.

Both Jason and Duke get caught in many, many, many explosions after that initial reveal, and it's always terrifying for the rest of the Bats. It gets to a point where Batman refuses to partner Duke and Jason together for literally anything, because they always act fucking insane. Big metal vehicle moving hundreds of miles an hour towards an unsuspecting civilian? That's okay! Jason will just throw Duke in front if it. Unknown, volatile substance potentially being used by a notorious serial killer to murder his victims? No lab testing required! Duke will just pour a whole pint of the stuff on Jason's bare arm to see how it reacts. Bomb that can't be disarmed? Why wait for backup when these two psychopaths can just grab the thing and jump into the harbor? Like, genuinely. The stress. Bruce is one particularly traumatic incident away from actually considering therapy.

birdification beam!!

what if Damian wasn’t sent to Bruce by Talia and instead decided to do a bit of early child-rebellion by running away to him himself. Talia, pissed off but too busy dealing with uprisings in the league to go track him down herself, calls up the person Damian is most likely to listen to other than her; his brother, who she trusts to keep him safe.

the thing is, Jason is 1: busy with his own missions atm 2: was also once a rebellious little asshole who liked to run away from home. he was Damian’s tutor once, he knows the kid can handle himself and he also knows if he CAN’T handle something he’ll contact Jason for help. he knows this because about a week before Talia called him, Damian called him.

Jason, phone balanced between his ear and shoulder: what do you want, i’m undercover

Damian: i require money for a fake passport.

Jason:

Jason, letting go of the guy he was beating up: alright you have my attention.

Damian: i am running away from home. i wish to do something ‘for the lore’ like the stories you used to tell me as a child.

Jason:

Jason ‘i’m going to ethiopia’ Todd: there’s some stuff in the fake panel under my bed. don’t tell me where you’re going, i don’t want to be complicit when Talia calls. also don’t die, because if you do i’m gonna make you eat dirt once you get out of the pit.

Damian: understood. if i am about to die, i shall call again.

Jason: have fun kiddo.

so Jason tells Talia he’ll ‘keep an eye out for any leads’ and then goes back to his normal business. league missions, his own missions, some outlaw shit, and eventually he ends up crime lording it up in Gotham. he’s a little confused when Tim Drake is seen swinging around as Red Robin rather than just Robin, but he got over his obsession with the Robin shit a while ago, so he ignores it.

until he runs into Batman and Robin. and there isn’t a mask in the fucking world that could hide his kid brother’s face from him.

Red Hood:

Robin:

Red Hood:

Robin:

Batman: why are you two staring at each other like that. what’s happening.

Robin:

Red Hood: *deep sigh*

Robin: are you going to tell mother-

Red Hood: -when you said ‘like the stories i used to tell you’.

Robin: *looks at the floor*

Red Hood: i did NOT think you meant running to a different country to find your birth parent. you fucking COPIER.

Robin:

Robin: …but you made being Robin sound so cool…

Batman: what the fuck are you two talking about?

Red Hood, pointing: you stay out of this, this is family business.

Batman: ????

Brain Dead, Tim becomes a halfa

This could be a whole fic.

It was supposed to be an easy bust. Tim had been excited, at first. He had discovered the discrepancies in Dalv Co.'s books. He had done all the legwork pinning Vlad Masters down like a butterfly. He had dug into the man's past and discovered all the questionable business transfers that had skyrocketed the man into wealth. So, when it came time to raid the man's mansion in Amity Park, Illinois, Tim was going to be there. He deserved to be part of this.

When they busted into the mansion they found it empty. The man was nowhere to be found, but they had a search and seizure warrant, so they searched the place. Tim let the Justice League and the SWAT team deal with the nitty-gritty of cataloging and removing Master's stuff and Tim went looking through the mansion.

It was in the library that he knew Masters had a hidden room. He could feel air flow coming from behind a bookshelf, and when he pushed against it, it swung right open. Stone steps led down, deep underground the estate. He radioed Batman to let him know what he was doing and started down the steps.

When he reached the bottom he heard voices. Tim pressed himself against the wall and listened.

"I'm not letting you escape, Vlad." a voice yelled, young and male.

"You won't have a choice, Daniel. Don't forget, if I go down, so do you." that voice was older. Probably Masters. Tim sent a silent message to Batman over his wrist computer.

"I didn't have anything to do with your shady business dealings, and if you out yourself, then that's entirely on you."

Vlad said something then, too quiet for Tim to hear. He leaned in just a little to catch the words, but his foot slipped on a step. There was no way they didn't hear that.

Sure enough, two people came around the corner, a young man with black hair and the bluest eyes Tim had ever seen and the man Tim had been trying to get arrested for the last six months.

Vlad Masters grabbed his arm in a surprisingly strong grip and pulled him out of the stairwell. "Well, well, well, look what the bat drug in." Masters sneered.

The boy, Daniel Vlad had called him, grabbed Vlad's arm and held up a hand, as if to physically stop the man. "Let him go, Vlad."

"Like you could ever stop me, Daniel." Several things happened all at once. Vlad pulled a strange looking taser out of his pocket and tased Daniel. The boy fell to the ground with a scream and a spasm. Tim aimed a kick at Vlad's face, but he was flung across the room and into some kind of device embedded into the wall. He hit the side of the device hard. There was a bright flash and blinding pain.

---

Tim didn't know when he blacked out, but he must have. Otherwise, he wouldn't be blinking into consciousness, staring up at the fluorescent lighting of an unfamiliar room. His whole body felt like pudding. He groaned and brought his hand up to rub his face but froze. Something was wrong. His black gloves were white.

"Red Robin!" That was Batman's gruff voice. "Don't try and sit up yet."

"No, let him sit up." That was the boy's voice. Daniel. "It's best if he gets oriented quickly."

"When I want your input, I'll ask," Batman said through clenched teeth.

"I'm just saying. Not like I know exactly what's going on with him."

"What is going on with me?" Tim asked, looking over at Batman, then the boy, Daniel. Daniel was in handcuffs.

"There was an accident. We don't know the severity of the damage, but I promise, I will find a way to fix this." Batman said.

"He's not broken!"

"Please, will someone tell me what happened to me!" Tim said, desperation leaking into his voice. He looked down at his suit and it was all wrong. His pants, boots, gloves, bandolier straps, and cape were all white, his belt was silver, and his shirt was deep forest green. There was something else wrong, too, but he couldn't put his finger on it. He put his hand to his chest and then he knew. He wasn't breathing. He didn't have a heartbeat. "Am I dead?"

"No," Batman said at once.

"Sort of," Daniel said, earning him a growl from Batman. "Lying to him and yourself isn't going to help anything," he said to the man before turning back to Red Robin. "The accident changed you. You're what's known as a halfa. Half ghost, half human."

"I've never heard of that. How is that possible?" he asked. even though he didn't have a heartbeat he could feel a panic attack building.

"It's rare. There are only three true halfa's in existence. You, Vlad, and Me. You have an advantage over us, though. You won't have to figure this shit out on your own."

Tim looked into Daniel's bluer than blue eyes. His whole world was crashing down around him. Everything would change, he knew. But maybe it wouldn't be all bad.

This would go double since Uncle Ben was raising Peter for more of his formative years and would have a greater impact on his personality and habits.

Peter being flippy and quippy aside, he absolutely would have more act more like Jason.

Heck he’d most likely inherit Jason’s fashion sense as well.

Looks like Jason + Acts like Jason? Yeah that’s totally Jason’s kid

Peter brings up Uncle Ben directly or indirectly and imagine the batfam think that Uncle Ben is Dick. They have it all switched around.

It does not help that Uncle Ben is a police officer, and so is Dick.

Hiii, stumbling out of my mindscape with snippets of Spidey in Gotham embedded in my psyche like thorns on cheap flipflops after a walk on uncleared nature.

I'm just dying at the fact that according to canon jason and Dick look so alike they could have mistaken for one another in their teens, so people seeing Peter might think he's the child of either of the two. And I die againnn. Bc imagine him seeing Jason (Ben) and reacting bc of course he would, and everyone thinks he's the dad??? Screeching.

REAL istg Peter in Gotham is gonna be the reason I fail my bio course and end up in debt for no reason,,, worth it

But no seriously!! I've seen 1 (one!) Fic of Peter getting mistaken for Jason's mini me (welcome to the show by prodby_error) and it SLAPS

Listen. Right ok listen. Things go down, the usual happens, batfamily is stalking Peter, with the assumption this is either Jason's kid from the future or he's a lab baby, doesn't matter, they're stalking him THINKING they know who the daddy is. Dick, among everyone else, is lightly teasing Jason as they try to bring the sassy spider child into their folds. Only, wait, hold up, they just got a DNA sample and Jason,,, isn't the dad?

Dick's hear drops when he sees the test results. He's the father? But the kids a total copy of Jason!

And, sure, Dick and Jason look notably different NOW, what with Jason's height and scarred and lazarus makeover, but Bruce has distinct memories of mixing them up, of calling the wrong name at the wrong black-haired blue-eyed teen.

Jason feels,, kind of sad. He'd already mentally adopted the kid, who isn't even his apparently, but also he's now an uncle???

Not sure how Dick would respond. Disbelief? Anger? Confusion? Adoption mode? Hit or miss tbh

Oh My God Another One

Danny: *laughing like a maniac after discovering a new power he could use to torment Vlad*

*Batfam arriving at the scene*

Danny, a bit high on chemicals: HI DAD! :D

Batman: ?!?!?

Red Hood: God not another one.

Red Robin: Black hair and blue eyes combo number four, now with meta powers.

Robin: Father your knowledge of basic intamacy practices needs to be revisited.

Batman: !?!?!?!?!?

Nightwing: Jeez B, don't you have enough already?

Stephanie: Right! It's just getting ridiculous at this point old man, pack it up!

Duke: He just blew up that construction site.

Cass: New brother.

Batman: ?!?!?!?!?!?!?!??!!?!
