Backstory:  In a world where the mcu, cw and dceu are one and the same. Extra points if you know which song the title is from. This came out of my pure imagination so if things seem weird, they most likely are. Came out of an idea about a scene where Peter was fighting the black cat and btw i watched birds of prey on youtube and i loved it. Say what you want, harley quinn is a fucking badass. So this is for her and Peter cause why the hell not. And dinah lance, that’s a canary. Plus, during the action part please feel more than free to play sway with me cause it’s a whole ass bop that im using to influence this fic. I also made up one hero that’s basically a marvel version of killer frost, her backstory is more developed in the fic. She’s an oc that may or may not make future appearances. As I write this fic I’m tempted to write more oneshots cause writing this is SO MUCH FUNNNNN!!!!!!)

Peter “Parker” Stark lived in a world of heroes, villains, secrets, lies, and hidden identities. How could he not? He lived in a world with the greatest heroes and villains, The Avengers, the Justice Leagues, and their iconic counterparts. He was on a line at his favorite deli shop when he heard the sound of bullets being fired. He sighed, ever since Ewan McGregor look-alike came to New York to rival up his father, New York, or as the criminals dubbed “Gotham” was a madhouse. 

He could come back to the deli later, he thought as he slipped on his mask and suit to find the Black Canary trying to defuse some thugs. Not far from her was the Huntress and the infamous Harley Quinn. 

A voice crackled in his comm, “Anyone on?” It was Natasha. She continued, “We’ve got Birdies trying to stop some robberies and they could use some backup. I’m not far, but we could use some help.”

Peter replied quickly, “I’m here Widow. Anything on these thugs?”

He quipped, getting some of the thugs' attention, “Hey, why don’t we leave the nice ladies alone and be good citizens?” He threw a punch to the thug that was trying to sneak up on Canary who caught the thug and slammed him to the floor. 

“Thanks”, Canary breathed out. 

Peter waved her off, “No prob, Widow’s on her way, what are we dealing with here?”

The Huntress replied, who by the way Peter thought had a sick superhero alias, “Thugs trying to steal a bank. Heard one of them talking about a bomb. Harley and the others are working inside. Which is totally not fair, I got a whole new crossbow that I’m itching to test out.” 

Peter smiled beneath his mask, “You just might get your chance very soon. According to my scanner map, we got some more baddies itching for a fight.”

Canary loosened her shoulders and brought her fists up to her chest, “Let them, we’ll swing it.” 

Natasha appeared not too long after, grabbing a pistol and cocking it, “Peter you go inside, Birdies, and I will take this on. I pitched a call to some others since the baddies decided to have a field day.” 

Just after she uttered those words, Elektra, Catwoman, Deadpool, Jason Todd, and Poison Ivy appeared. 

Peter tilted his head, “What’s in the bank that’s so powerful that even Deadpool wants in?”

Natasha replied diligently, “A super rare diamond worth a lot more than me and you. Harley’s guarding it inside, after taking out everyone inside there already cause that’s her.”

“You got to say,” a female voice aired as boots thudded softly next to Peter, “Girl knows how to get shit down.”

Peter turned, grinning under his mask at the white-haired woman who also happened to be his best friend as well as his girlfriend, “K-Frostbite, nice seeing you here.”

Frostbite smirked, letting ice stretch from her fingers, “And miss out on a fight like this? Elektra and I have a score to settle.” 

Elektra only twirled her sword, “You lot aren’t going to be able to stop all of us.” She gestured to Catwoman and Ivy’s goons not far behind. Plus the ones that the Birdies had handled were starting to wake up. 

Poison Ivy was smug as she outstretched her arms, revealing a plant armada that reigned not too far behind. 

“Well lucky for them, they're not alone.” A blue cape flashed in with a gold lightning bolt across her chest. Ms. Marvel grinned as her fist enlarged. She looked up at Dinah, “You’re the Black Canary, I just have to say I love you.”

Natasha brought the team back to attention as a female dressed bat appeared by her side, “Alright here’s the plan. Kick ass, and don’t get hurt. You do, you walk it off. Barton, Spiderman, and Huntress, you join Quinn if things go sour. Got it?” 

The Black Widow was met with nods and sounds of approval. The villains started heading towards them, determination set on their faces. 

Batwoman, clearly irritated at seeing some nemesis retorted out of annoyance, “DP again? Didn’t Stark and Barton just handle him last time?”

Barton or Frostbite answered, “Yeah, and if I recall you kicked Ivy’s ass a few days ago. Might want to punch harder. Watch out for Ivy, she’s real toxic if you know what I mean.” She sent an ice blast towards Elektra, calling out a challenge. 

Peter punched a thug, and then swung his legs across the man’s ankle, sending him crashing to the ground. He ducked behind him as Catwoman started shooting. Kamala waved and gestured at her hand and then back at him. He smirked, sending her a thumbs up. Peter swiveled towards Catwoman, “You know I gotta say, your sister is just as persistent as you. What? No monologue this time?” He jut out his wrists, sending two webs towards her and keeping her in place against a building wall. 

Something hit him on the back of his head and sent him crashing to the ground. Peter groaned as he turned around to find one of Ivy’s plants standing tall towards him. He muttered under his breath, “I’ll never understand how she does that.” He moved to get up, but he didn’t realize that one of the plant’s leaves was snagged around his ankle, so he slipped back to the ground as he stood back up. The plant made a gesture as if it was mocking him as Peter struggled to free himself. 

Suddenly, a zing sound pierced his hearing as a Batarang cut him free and then a giant hand smacked the plant to the ground, taking Ivy by surprise. Batwoman took Ivy’s reaction as an opportunity to knock her off her feet. Batwoman spoke, “I’m afraid we have another problem.”

Peter followed the woman’s gaze to where thugs were trying to force down the bank’s doors. Shit. He voiced, pressing on his comm, “Kir, Huntress, I think it’s time for us to help Harley.”

“One second!” Kira’s voice was laced with a grunt as she swung her body around Elektra’s, pinning her to the ground. She snatched Elektra’s sword and let ice creep up it and then shatter. She then punched Elektra in the jaw, knocking the older assassin out. 

The Barton ducked under a thug and then blasted ice towards him, pinning his feet to the ground, rendering him stuck. 

Huntress smirked, “Now that’s a badass.”

Kira shrugged with a smirk of her own. “I try. Now let’s help Harley before she takes all the fun.” 

God, Peter loved her so much. 

The trio fought through the mass of thugs who had broken down the bank door. Peter found himself with a somewhat strange sight. Harley donned her roller skates and hammer, aggressively slamming the head of it over a man’s. She turned to them, face an annoyed question mark, “Well don’t just stand there, ya gonna do something or what?” 

Peter shook his head as he flipped a thug over on his back, “It’s nice to see you again Quinn.”

“Hey,” Harley spoke, wiggling a finger playfully in his face, “Don’t get smart with me with Stark, You’re smart smart but I have a PhD.” 

Kira chuckled, “Yeah Pete. She’s got a PhD. You got good luck and a great charismatic personality that I love so much, but a PhD? That be the cherry on the cake.” She winked at him as she kicked a man right in the um, area and then spun-kicked him in the kneecaps. 

A man grabbed her from the back and put her in a chokehold. She grunted, trying to swing her legs and flip him over but failed as the man was much larger than her. Peter jutted a web at his arm, pulling him right off his girlfriend and into a trio of impeding thugs, taking them all out like a bowling ball at pins. He asked as Kira rubbed her neck, “You okay?”

Kira nodded, bringing her fists to her chest, “Yeah, thanks.” 

Peter didn’t get the chance to wave her off as his spidey senses blared, indicating to him that a fist was about to make contact with his head. He ducked, swinging his leg across his ankles and then jumping back to his feet, “These guys just don’t stop do they?”

Meanwhile, Helena was shooting people left and right with her new crossbow and having a whole thrill out of it. She punched a dude straight in the nose and then fired where her fists couldn’t fly. What she didn’t notice was one of Ivy’s henchmen with a gun aim for her. But the Huntress did notice his body slump unconscious as Harley slammed her hammer over his head. 

Kira’s voice filtered through the comms, “These guys keep on coming, there’s only so much more we can handle.” She grunted as she kick- jumped, “This is getting super annoying!” 

Harley agreed as she twirled her hammer, “You're not wrong kiddo." She paused tilting her head, "Wait, who’s guarding the diamond?” 

Peter was about to reply when someone knocked him off his feet. A woman was clad in all black and holding the diamond that they were supposed to be protecting. Well shit. And it had to be the Black Cat, Catwoman’s younger sister who also happened to be the only person that’s as even more obsessed with me than Mysterio. 

The Black Cat’s voice was silky as she tsked, “What, were you looking for this?” She smiled at him and then back at the diamond, “You heroes try too hard, just to fail so easily. To be honest, I don’t see why you side with them, you and me, we’d be unstoppable together. With your help, you’d make this whole extraction so much easier.”

Peter hissed at his nemesis, “So all that outside was a ploy then? So you could take the diamond. There was no bomb after all.”

The Black Cat practically purred, “Looks like you’re as smart as they say you are.”

Peter quickly snatched the diamond from her claws as he shouted to Kira who ice blasted the woman against a wall, knocking her out unconscious. 

Kira pulled him to his feet, “You okay?” Despite the easygoing expression that rested on her face, her voice was laced with concern.

Peter nodded as he handed the diamond to Natasha, “Duh. Now,” he offered to Kira, “Sandwich at Delmar’s?”

Kira beamed, "You know it."

Harley piped looking at him and Kira, “Can I join? I love grilled cheese sandwiches, they just really work wonders on ya!” 

Peter chuckled, “Sure Harley…”

Harley brought her fists down, exclaiming, “Yes!”

“If,” Peter started, “You promise to pay. And not try to steal the cat.”

Harley pouted, “Fine!”

A/N: Thoughts, opinions, comments? Frostbite’s just a character I came up with to make things more interesting. She’s Clint’s kid that was kidnapped by HYDRA and experimented on and she’s been a part of the Avengers since 2012. I still ship Peter and MJ together obvi, but in these types of one-shots, I like to experiment and have some fun lol.
