The Greatest of them All.

[sketchysubstance]

I made a comment on here saying I headcanon that DC is a fictional universe within the MCU and marvel is a fictional universe within the DCU and I'm watching Spiderman (2002) and Aunt May just said "you're not Superman, you know."

MY HEADCANON IS CANON?? SUPERMAN (and likely the rest of the DCU) EXIST AS FICTIONAL CHARACTERS IN THE MARVEL UNIVERSE?? You can't imagine how happy this makes me.

It's ironic that 2 heroes that are seen as the greatest champions of America are a child of immigrants and an immigrant.

Randomly crawling onto the wall, the fourteen year old smirked watching the ten year old Robin walk through the hallway. Ready to prank Damian, he lifts his hand to web him. Sadly before he could do that, Damian throws a ninja star at the poor spider hero. Y/n yelped and jumped from it.

“Stop trying Parker, you’re not the best at stealth.”

“Funny that you say that.” The spider male dropped by Damian’s side, walking by him as Titus barks gently, acknowledging his presence. “Awww hiii Titus! Such a cute doggie! Such a cutie!”

Damian could only stare at the male as tim comes out his room. “Y/n? What brings you here?”

“Oh i got bored so i came to visit the pipsqueak here.” The male placed their arm on Damian’s head. Damian’s face scrunched up and shoved y/n from him. “Don’t touch me.” Damian says sternly while Tim leaves the two kids in the hallways with Titus. “Jeez,calm down pipsqueak. It’s not my fault you’re short.”

This ended with a chase between the two boys. Titus barked and followed them. It ended with Damian tackling the teen down the ground and pinning him.

“Ow! Ow! Ow! Let me go pippy! Ahhh! Im sorry, Damian!” Damian narrowed his eyes as he let go of his arms. “Remember where you stand.” Couldn’t help to talk, y/n spoke. “You mean, lay?” Damian goes to grab y/n’s fingers before Alfred came forward. “Master Damian, Mr. Parker, dinner is ready.” Damian nodded, giving the butler a simple “thank you pennyworth.”

Y/n was finally let up whilst Damian crossed his arms staring at the male. “Is dick here?” “He is.”

“I just hope dick doesn’t tell anymore lame jokes during dinner.” “Please don’t jink, Parker.”

“Too late..” y/n chuckled and looked away from the small Wayne, not being able to see the small curl of Damian’s lip.

i’m sure we’ve all read at least one or two “peter parker in gotham” fanfics. they’re a personal favorite, especially when they’re done well. and i do get why peter is always in gotham, but…

…why not put one of the batkids in peter’s new york? i think it’d be interesting.

my personal favorite is tim drake, but i do think any of the batkids would be absolute comedic gold. here’s why:

1)

dick would’ve 100% “fallen” into some portal during a fight and ended up in new york. at first he thought it was just that, the portal teleported him into new york. whatever. that’s like a regular tuesday for him.

but then he saw some news program (“The Daily Bugle”) talking about some… Spider-man guy that dick’s never seen! never heard of! who the fuck was this guy and where is dick!?

he momentarily freaks the fuck out before giving himself a mission; find out where the fuck he is and then get back home. easy enough. he’s been stranded before. it should be easy for him to get back home.

at least he thinks so, until he bumps into the aforementioned Spider-man guy, who is surprisingly friendly despite the strange way they move. guess the spider thing was fr.

they bond over acrobatics while peter is attempting to figure out how to build a teleporter (he figures it out quicker than expected and spends far too much time styling it)

2)

jason was on a mission with the outlaws, and one thing led to another and now he and the rest of his team had been teleported to different locations.

he had assumed that bullshit ray gun was some dollar general version of the big stuff until he walks head first into a humongous spiderweb that sticks to his helmet.

jason fucking hates spiders.

he freaks out (duh) and yanks his helmet off and stumbles away, staring at the way it just… hangs there… and suddenly he knew for a fact he wasn’t supposed to be there.

he looks around for a while after that, helmet-less and confused as all fuck. he thinks distantly that maybe he could just restart here. no joker, no batman, no nightwing, no responsibilities. he could make it work.

on his walk, he comes across a mugging. he attempts to get in there, of course, but he’s completely outgunned by some soft-looking fuck in red spandex.

red spandex! what the fuck!

the red-spandex person cleans the mugging up swiftly, and then they turn around to see jason there. they freeze, their mask scrunching up.

jason tries to shoot at them, but his hands get webbed to the wall before he could even reach into his pants.

he’s mildly impressed.

3)

tim is completely whelmed when he just… disappears on his walk back to the manor after school. there’s no portal, no laser beam, no spell… he just… trips once and then falls through the sidewalk. it was so fucking weird.

he’s caught off guard as he’s spit back up from the other side, coughing and heaving breath after breath into his lungs as he takes in his surroundings. he’s in some bad smelling alleyway, and he could feel at least three other people near him.

he’s in a loud, busy city with tall buildings and aggressive crowds. it’s too bright to be Gotham and too gloomy to be Metropolis.

where is he?

he stands shakily, brushing himself off before looking around again. more focused this time, though. he focuses on his location.

he turns to see a homeless man staring, and before he could even open his mouth, the man screams before hissing at him and running the opposite way.

what the fuck?

he tosses his hands in the air before getting cut off by a snort, and he whips around to see a lean, thin, soft-looking person in red and blue spandex. their face is covered by a mask, but even then their mask is so animated that tim feels immediately impressed.

“you scared jimmy.” the person says simply, tilting their head.

“you scared me.” tim responds, tilting his head slightly to mirror them. they laugh, their white eyes narrowing.

“you’re not from around here,” the person says slowly, leaning forward slightly. “let me guess… jersey?”

“huh, how’d you know?” tim snorts, shaking his head.

“accent.” the person shrugs.

the two bond quickly, over everything and nothing at the same time; and they simultaneously figure out that tim is in an alternate dimension and they work together to figure out how to get him home.

by the time tim returns to gotham, he’s picked up more of peter’s spider-like attributes than he’d ever like to admit.

4)

damian doesn’t want to admit that he went head first into a villain’s trap, but… he did.

in his defense, his father did nothing to stop him from doing it. truly, it’s his father’s fault. not his.

he blinks awake to find himself in a puddle, and theres cold rainwater falling onto him and soaking into his suit. it’s uncomfortable, cold, and he feels like curling into a ball and hiding.

but he can’t. he can tell he isn’t in gotham. what if he was somewhere unsafe? he needed to stay vigilant and aware.

he sits up, and immediately feels eyes on him. he looks around, paranoid and on guard.

before he can really understand what’s happening, he sees a person dressed in red spandex hop off what looks like a human sized spider web, landing on their feet with perfect, practiced elegance.

“you’re too young to be dressed like that,” the person begins as they walk closer. “too young to be what you are.”

damian scoffs and stands slowly, hiding a wince as he leans on his left foot. something’s sprained.

“hardly.” damian shakes his head, and the person tilts theirs in response.

“i had a feeling, but i had hoped i was wrong.” the person says softly before walking closer.

the last thing damian remembers before waking up in a warm bed was a warm hand grabbing his arm gently.

the person in red spandex reveals themselves, and they talk. for a while. damian ends up really liking them, especially after they tell damian all about the spider that bit them.

he almost doesn’t want to leave.

5)

while shadow traveling (like in pjo?), duke goes a little too far. he knows he should’ve gone back, but he’s never gone this far and he was so curious it ached.

so he kept going until he walked out the other side, into a very busy alleyway. it smelled of garbage and weed, which didn’t necessarily bother duke but it did tickle his nose slightly.

he decided to figure out where he was first, and then worry about getting back. if he found out a way to get from one timeline to another, then bruce would be extremely grateful to have duke’s abilities on his side.

right?

duke could only hope so.

he walks around for a while, ending up on a very busy sidewalk. he sighs and steps next to a hot dog cart, to which the man stares at him strangely before shrugging and preparing a hot dog. duke goes to refuse, but hears… something in the distance.

he didn’t have time to react before the hot dog cart’s owner held the hot dog out to the street, and a person dressed in red spandex swung past and snatched it up. then, a few seconds later, a five dollar bill was… webbed to the side of the hot dog cart.

duke stared in awe, his eyes wide as he watches the scene. he immediately searches for a library, and immediately begins looking up who this person in red is.

does he forget that he isn’t dressed like a normal civilian half way through? yes. does he fix that? no.

he tracks spider-man down pretty easily, and asks them a million questions all at the same time, to which his mouth gets webbed for. spider-man snorts and answers every single one of his questions.

duke feels so heard it hurts his heart.

he shows spider-man how he did it, bids them farewell after letting spider-man take a picture and several notes of duke’s powers.

duke goes back to gotham feeling light and warm, a smile on his face.

6)

cassandra woke up on a rooftop, feeling sick and tired. she assumed it was some sort of alternate dimensional travel, considering she had been in a space ship beforehand and now she wasn’t.

she uses context clues as well.

the loud bustling streets, the tall but modern buildings, the laughing, the music — none of it is gotham. she knew that very well, but she was still rather confused.

if she wasn’t in space, if she wasn’t in gotham, where was she?

she lets out a silent grunt before slowly sitting, and then standing up. everything hurt. she guessed her spaceship had crashed into some sort of… cosmic ray or portal and she fell out of it. made the most sense.

she looks around slowly, taking in her surroundings like she was taught. she sighs softly when she turns up empty handed, back at square one.

one thing she does notice is the obvious eyes on her. the person isn’t trying to hide, which means she probably in their terf. that isn’t good. not good at all.

cassandra barely turns her head before she feels something pulling at her wrist. looking down, she finds her wrist being tugged by a synthetic spiderweb. it was sticky, silky, and had far too much pull to it.

she twists her arm and pulls on the webs, and then the person comes forward with a heavy step. shiny red and blue spandex fits this person’s body like a glove, and the mask they wear is far too animated to be authentic. must be a function.

the two fight, and as they do cassandra watches the person’s spider-like tendencies. they move with suck fluidity that she feels inferior for the first time in a long time. she’s left in awe, almost.

eventually, she forfeits. she knows when she’s about to lose a fight, when it’s better to stop and give up then die fighting. even if this spider person doesn’t seem hostile, just protective.

“i’m not from here.” she states simply as she’s allowed to stand.

“i know.” the person responds, and cassandra feels more at ease than she did beforehand.

the person - peter takes care of her during her time in new york. gives her a bed, hot food, and even a fake identity for the time being. it works, and eventually she’s back home.

sometimes she tries to mimic peter’s fighting style, but without his abilities, she comes up short.

but the memories are warm and fuzzy and she likes to dream about it.

Extra notes: I should be studying instead of writing this. Also omg I got so many requests in just a few hours, thank you very much!! I'm writing them all!!

General masterlist | A Day in Life - Series masterlist

Since most of your days became filled with stress and anxiety, you started appreciating even more moments where you could just forget all your problems, from small ones — like, lack of motivation to go to the gym, bad hair days and an ingredient you forgot at your fridge and became rotten—, and big, out of your control ones — like seven superheroes, who you see almost everyday, stalking you.

Your boyfriend getting back was one of the best dic(k)strations.

Bucky was a sergeant, he spent weeks, even months, away from you on missions. It was hard, but you were both busy people, so your mind was usually too stimulated to think about boy problems only all day, most adults were, and you believed the hard work would be worth it one day. The future was hopefully bright.

The League never mentioned him. Actually, some of them implied more than once that they thought you were available, so they probably didn't know about your relationship. You didn't use much social media and your boyfriend got especially busy this year, so it made sense.

He paid for you to get your nails done earlier and took you to a nice restaurant. After that, Bucky took you for a walk around the city, lively and beautiful even at night, and stopped at the park where your first date happened. Everything was fine, until he got on his knees. Suddenly, seven, mostly colorful, figures descended upon you from out of nowhere, screaming.

— (Y/N)! YOU CAN'T MARRY HIM! — Flash’s voice startled you, confirming your suspicions to who the group was.

You growled.

— SERIOUSLY? LEAVE ME ALONE! IT'S MY DAY OFF! — Bucky, who had swiftly gotten up with his fast reflexes as soon as the heroes charged, blinked at the sight. He looked between you all.

— Doll? What’s this? — You looked apologetic at him.

— Sorry, Bucky. Since I got my job, my bosses got… Protective over me… — You didn't want him to get hurt. Bucky and his friends had a great sense of justice and hated bullies. He would surely want to do something if he knew the true extent of things. You also didn't want to ruin the vision he had of his idols.

Since their obsessive behavior started, you just counted your lucky stars that they would just get tired of you one day or wouldn't sabotage your relationships. They seemed fine with you having friends, but dating was different.

You turned to the League.

— Go! — They shook their heads.

— You can't trust this bastard, darling. We have proof of his betrayal to you. — You looked at Wonder Woman skeptically and crossed your arms. Bucky gulped.

— Oh, really? How so? — You raised an eyebrow.

Batman fiddled with his wrist computer, a second later, a protection was shown and different pictures and videos of your man talking and being very intimate with someone very familiar to you appeared. Your stomach churned and your heart ached.

— This is fake! Doll, you have to believe me! — Bucky cried out and got in front of you, holding your shoulders, trying to cover your vision from the images. You took a step back and kept looking at the images.

The League had more than enough means necessary to fake all of this, but you knew Natasha was Bucky’s ex, and they were still friends and coworkers, even with their intense heartbreak. You sometimes got insecure and worried since they spent so much time together, but he always told you you had nothing to worry about…

You gulped.

The League was all glaring at his back while he shouted a hundred words per minute, desperately trying to convince you he was telling the truth.

Superman growled and walked forward until he grabbed Bucky by his shoulders and pulled him away from you.

— Stay away from them, you asshole. (Y/N), I would never do that to you. — You ignored Green Lantern's words, like you were doing since the pacifier incident. You knew he was getting desperate and that made you specially scared, but at least he gave you some distance.

— Not now. — Batman took a step forward. — A few hours ago, we discovered your relationship. For security reasons, we searched, and found these pictures and conversations from his second social accounts, that he uses to commit his cheating.

— He didn't try to hide much, he thought he wouldn't get caught. — Flash stated.

— I-I need more proof… These could be old… — Your first words spoken made Bucky shut up. Mind scrambling for something.

— Let the Lasso of Truth speak for him. — In a second, the Lasso was thrown around Bucky's torso and he was squirming. — Speak, you worthless mortal! — Wonder Woman ordered.

Bucky was able to struggle for a few seconds, before he blurted out.

— It's truth! It's truth! I told her we broke up and started dating her again! I thought I could have you both at the same time!

You gasped. Your hand shot to your chest.

Flash was on your side in a second, trying to hug and comfort you, but you pushed him away. You started crying from heartbreak and anger.

— HOW COULD YOU?! — You glared at him and pointed at his face.

— Doll… I swear I love you both. But I'm also narcissistic, insecure and look down on women. — The Lasso was really doing its job. You laughed humorlessly.

You had nothing to say anymore. No reason to stay. You took advantage of his tied arms and got close, punched his nose, and stomped away.

The League contemplated going after you and trying to bring you comfort, but Batman and Martian Manhunter decided to just let Bucky go (after intimidating him so as to not get close to you again) and follow you discreetly, watching you from the shadows, intervening only if necessary.

I have a soft spot for Peter Parker in Gotham fics, but how about Peter in Central City?

Post NWH Peter Parker ends up in the DC universe. He starts being spider-man there, makes connections and befriends other heroes. Eventually, Peter overhears someone mention how everyone forgot Wally existed because of speedforce shenanigans.

Naturally, Peter has a lot of emotions about his own situation and goes to the only other person he thinks will understand his predicament for advice (even if their situations were pretty different actually).

Peter kind of fails to properly explain himself and the alternate universe thing though. So Wally comes to the obvious conclusion that Peter is someone he knew, or at least heard of, before the spell. When Wally realizes all the issues Peter is having adjusting to life without a legal identity he offers to take him in.

(It would be fun to combine this with birdflash and 'Richard Parker and Dick Grayson are the same person' AUs.)

(I also think it would be funny if Peter said, "Dr. Strange did it." Like imagine Hugo Strange chilling in his cell when the bats pop in and demand answers he doesn't have lol.)

Bride: I’m not the one you should worry about

(Y/N) - Venom bursts into thru the window and grabs Ilana…

Ilana: Venom! (Y/N)! Y-you wouldn’t hurt me…you love me

Y/N: you know Venom and I can forgive a lot of things. Conquering, lying, bribery, petty theft—

Venom: but Nina was our best friend!

Bride: Venom, (Y/N), she’s all yours

Venom: thank you

Venom chops down on Ilana’s head…

Reverse Spidey in Gotham AU

Something happened in the DC universe that caused the Bats to be thrown into a new universe. There they meet a lonely Spider and begin to get used to things in the Alternate New York.

[jeonstellate]

currently writing the fic for this idea prompt, and i’m highkey pissed i can’t fit these in:

(won’t provide additional context, except that peter is six who kinda acts a little younger because . . . reasons.)

“Happy birthday, Alfred!” Peter flashes a smile that gets everyone, sans Jason, in the room stilling. They know that smile. “Here’s Uncle Jay’s gift for you!”

“It’s from all of us Outlaws,” Jason corrects while his nephew hands over the wrapped box to the Wayne family butler. “And Peter and Lian.”

Before Alfred, or anyone else, can say anything, Peter deems it important to throw his uncle under the bus right there and then. “Auntie Artemis said Uncle Jay accidentally left it at home because he forgot to set an alarm.”

Some can’t help but chuckle with amusement. Children really don’t have well-installed filters. “For shame, Jason,” Steph chastises playfully.

Peter notices the cakes on the table and leans forward dangerously without any warning. Had Jason’s reaction time been any slower, the former would’ve surely face-planted onto the cakes below.

“Careful, buddy,” he says after jerking his nephew closer to his chest and further from the table. He almost sighs in relief upon averting a crisis (read: Kori’s disappointment). “You don’t need to be that close to look.”

Peter doesn’t pay him any mind, green eyes never leaving the desserts that have captured his attention. “Is this one for you, Uncle Jay?” He inquires after a moment, pointing at the cake with Happy Birthday, Jason! elegantly written on top.

“Yeah.”

Peter hums a note that doesn’t sound impressed. “I like the one me and Lian decorated better.”

Jason doesn’t know how else to react to that besides avoid looking at Alfred, who baked and decorated the cake his nephew doesn’t seem to approve of. Everyone else is too stunned to move.

Jason follows what caught Peter’s attention on the ceiling. His eyes land on the unsuspecting chandelier.

“No, Peter,” he shuts down the idea barely brewing in his nephew’s head. “You can’t swing on the chandelier.”

“Aw.”

Somewhere in the room, Duke can’t believe his ears. “That’s hereditary? How the—”

Peter fixes him a stare. Eyes slightly widened, bottom lip slightly pushed out. He wisely averts his eyes. “Don’t give me that look. Artemis will have my head. And that’s if your mom doesn’t get to me first.”

“Jaylad, you’re injured. You shouldn’t be carrying—” Bruce starts to say while inching closer to where his third eldest stood.

Jason is quick to react. “Nice try, old man, but I know what you’re trying to do.” He shifts Peter to his other arm, the one that’s further from his adoptive father, and straightens his body even more in an attempt to hide his nephew from the other’s view. “I won’t let you sweep him away.”

“I’m not—” Bruce starts again, but this time stops in middle in his own accord. In a softer voice, he eventually admits, “I just want to hold him.”

Jason doesn’t let up his protective stance. “Peter doesn’t like strangers carrying him.” To strengthen his argument, he turns for back up. “Right, buddy?”

However, much to his utter astonishment, the boy that has been attached to him since he showed up unannounced is no longer where he last saw him mere fifteen seconds ago. Instead, he’s in the arms of the second eldest Wayne child and is now holding a glowstick.

Jason doesn’t even have a clue when the transfer must’ve taken place. He didn’t feel his nephew detach while his eyes were locked on Bruce.

Cass smiles triumphantly as she rests the child on her hip.

“Uh-huh!” Peter confirms enthusiastically, unaware of — really, uncaring for — how his current position is an unignorable contradiction to what he just agreed to. He waves the glowstick with fervor. “Look, Uncle Jay, I got a baby lightsaber!”

Of Warriors and Worlds - Chapter 2

Okay. I gave in and quickly finished editing chapter 2 of my fic and posted it!

Chapter 3 will have to be posted sometime next week after my wedding.

Thank you to those who enjoyed reading chapter 1. If you're giving the story a chance for the first time, I appreciate it! If it's not your cup of tea, no worries!

Summary below:

There are worlds upon worlds, realities upon realities, each with its own heroes, struggles, and tales of love and loss. Some destinies are written in the stars, others forged through choices. This story bridges two Earths—not bound by fate but by the will to endure.

In one world, James Buchanan Barnes seeks redemption after lifetimes of war. Haunted by his past as the Winter Soldier, he navigates life after the Blip, pulled into battles—both political and personal—as he reclaims his identity. In another, Lyra Jor-El, Superwoman, a warrior born of strength and loss, falls through a rift and becomes a stranger on a new Earth, fighting to belong while holding onto who she is.

Together, they face not just external threats but their own haunted pasts and fragile hopes. Bucky and Lyra find themselves at the heart of a new team—born not of trust, but of necessity. Even as they face the Void, they must confront their own battles and a love that could bridge two worlds.

This is a story of warriors and worlds, of love forged in conflict, and of choosing purpose when good and evil blur. Watch closely, for it’s not the world you come from that defines you. It’s the world you choose to fight for.

Spider-Man and Nightwing meet and bond over their acrobatic move set, but it’s just Dick going “how the HELL did you stick your landing when your form is that horrendous” and Peter finally has to admit to someone that he doesn’t actually know how to do any flips in a professional manner, he just cheats with his sticky powers and super core strength

Hey, more Uncle Eddie brainrot, but this time it's Marvel-flavoured!

This one is lazy because I have the insomnia again, thanks menstrual cycle.

I can't even be arsed to string it together confidently, this is a build-your-own prompt.

Eddie Brock broke into Drake Industries and met his future hubby there in the first Venom movie.

Tim Drake could be related to that Drake. He could be there, doing his own investigating. (This could happen at so many points in the timeline. During Young Justice? After Jack makes him quit Robin? Red Robin Gap Year? Before Tim becomes Robin? Endless potential for faffing about with canon!)

Eddie and V end up together, but so also does Tim and another symbiote.

Just. Imagine Tim and Eddie going through the first Venom movie, with Tim trying to hide his new alien buddy from his evil relative while also trying not to eat anyone. He'd figure out the trick with the Runner's High stuff quickly, I bet. Be able to afford a lot of quality chocolate. Go eat some harbor seals idk Tim is desperate not to break his morals.

He and Eddie keep in touch when he goes back to Gotham.

I really like the idea of this being a pre-Robin Tim, because then he and his symbiote get to have more fun hijinks. They're this eldritch blobby creature following Batman and Robin around. They're probably vaguely bat-shaped. Guys they might have cute lil pointy ears.

They could change canon so much and it'd be so fun to see the differences.

Eddie Brock comes to work in Gotham to stay close to his fellow host friend? Suddenly there's two Creatures hanging around and Batman is Concerned about invasive species. Green Lantern is hyperventilating at learning there are Klyntar in Gotham. Suddenly Hal has to pull off the political maneuvering of a trickster god to keep Oa from making an enemy out of Batman. (I like a Hal who gives Bruce a hard time but who will also be the first to back him up if his plan is solid. B and Hal don't let each other get away with a lot of bs. They're siblings, your honor)

Idk have some ideas I guess, I'm going to focus on projecting my cramps onto jkr.
