Disclaimer: I do not own Marvel Cinematic Universe, Buffyverse or anything else you may recognize

And here we are with the final part of this MCU/Buffyverse series called 'Spider, Slayer, Vampires and Avengers', and this one is gonna be something- the epic and grand finale!

Anyway, I'm not gonna follow any of the Buffyverse comics since outside of 'After the Fall' and 'Angel and Faith', I really don't like any of them, but even the latter one needed the horrible Buffy Season 8 to come into existence. And 'After the Fall' got prevented in the last fic.

Plus MCU Phase 4 too outside of 'Spider-Man: No Way Home' I really don't like, though I found 'Hawkeye' decent so there's that, but that's it. No Way Home is amazing though, I'll give it that.

But anyway, this fic is gonna be fun. So first of all, I'd like to thank my friend Brainstorm Sorcerer very much for all the help and even scenes he gave here, I couldn't have done this without him. I made bullet points on what all should happen in this story in order, and he is the one who expanded them for me, so thank you very much.

And I'd also like to thank Bl4ckHunter, Stand with Ward and Queen, Marcus S. Lazarus, Rutkowski, Sayman, gammaxmen80 and OmniIBIBUltraInstinctGodzilla for their suggestions here.

So here we begin.

Chapter 1- RSVP yes

New York City

A man covered in various clothes, wearing a hat and glasses while covering his face entered a bank where the people were working.

"Give me money or you all die!" The man screamed as the people all looked at him, then seeing he was unarmed, shrugged and continued working, ignoring him.

"I said give me money or-"

"Security!" A female banker cried out as the two guards walked in to throw him out.

"Should have taken the out when you could", the man said as suddenly yellow electricity sparkled from him and he raised both hands, sending the guards flying off, scorched at various points, the people all screaming in fear now as some ran here and there.

"I am Electro! Remember the name!" He then fired his electricity here and there, destroying stuff, and aimed his hand at one more banker before throwing a bag. "Here, give it all to me!"

The terrified man put as much money as he could into the bag while the female banker pressed the alarm to call the police.

Electro ran out of the area, looking here and there, about to make his escape when someone knocked into him, kicking him with both feet as he was sent flying off.

"You checked both sides of the street, props to you for that, good thing to do. But you didn't check the sky."

It was Peter Parker aka Spider-Man, who now hung onto a sign nearby, looking down on Electro who sneered in rage.

"Spider-Man! You cannot beat me! I have great power!" Electro boasted.

"So did Thanos, Magus and Glory but they were beaten too", Peter shrugged as Electro fired a blast at him which he leapt away to avoid. "Strike one!"

He kept jumping and swinging to avoid more strikes, then swung on a pole and swinging towards Electro, kicked him again as his bag now fell off while he hit the wall, then fell down onto the ground.

Peter crouched near him.

"See? You can dish it out but-"

Electro fired at Peter and this time he was hit as he went flying off into the air towards a signal tower, where he grabbed it and flipped, sticking onto it. "My big spider mouth."

"You can't escape me Spider-Man! This is my playground!" Electro charged at him, spewing electricity around as he then fired at the tower, lighting it up, and Peter let go, flipping around through the tower expertly when his phone rang.

Electro stopped for a second as Peter grabbed the tower again and picked up. "Now's not a good time, Dawn."

"Look, Angel and Cordelia have invited us to the wedding and we have delayed our response so far so-"

Peter had to let go and flip around again as Electro once more launched his barrage onto the tower. "Come on Dawn I am in-"

"RSVP yes or no?"

"Yes! Yes! The two of us and Felicia are all going!" Peter said when Electro stopped for a bit again and Peter grabbed onto a tower. "Experimenting with electricity right now. Gotta go! Bye!"

"Bye!"

The call was cut as Peter flipped again due to Electro launching his barrage, but then he fired directly at Peter who was hit and sent flying off, hitting the ground as he groaned in pain, one of his web-shooters fried too.

"This has got to suck! Why couldn't I think of insulating them before I met a villain whose superpower is controlling electricity?"

Police sirens were then heard blaring loudly as the cops arrived and aimed their guns at Electro.

"You're under arrest! Hands up!"

"Sure officer", Electro raised his hands as electricity spewed out, hitting the cars so the cops had to run around to avoid it. "I am power, I can take all I want and be on the top! You all are nothing! I will-"

He was suddenly hit by water from a fire hose, which sent him to the ground, doused out now as Peter and 2 firemen who were holding it shut it off now. Peter had put on a fireman cap as well.

"Yeah, that's it, nice job guys", Peter high-fived with one of the firemen. "John." Then he did the same with the other. "Big Mike."

"Yeah!" They said as they high-fived him.

"Nice work guys, it was a pleasure doing business with you", Peter said as cops approached the now neutralized Electro. He seemed to be trying to move but was too weak to.

Later, as Peter was swinging, he saw a little kid with a project model of nature being bullied by some bigger kids, and so jumped down between them, making the bullies back off and run away.

He then put an arm around the kid. "You made this?"

The kid nodded with a cheerful smile.

"What does it do?"

"Here", the kid started showing Peter as they sat down in the alley together.

At the same time, Faith was on her laptop while sitting on bed, trying to write a story, though the basic premise was all that she had thought up. Plus she was taking inspiration from hers and Buffy's lives as Slayers for this, though superheroes like the Avengers did not exist in this world she was creating.

The main character was a wandering supernatural fighter called 'Hope', and she had disowned her last name.

Then suddenly a growing Bear hopped into Faith's lap, yipping and wagging his tail. "No, cutie, mommy is working."

Then Bear gave the puppy eyes.

"Not the eyes. Bad dog, don't give me the eyes!" And she broke. "Damnit! Okay!"

She set the laptop aside and started adoring her soon-to-be-not puppy, patting his head and running her hands through his fur as he barked and yipped happily. Faith baby-talked to him as she lifted him up. "You're such a cute little thing."

Bear licked her nose as she grinned, looking at a photo nearby that had been taken a few months ago. In that picture, she stood with Bear, Cordelia with baby Connor and Willow with a little kitten.

Faith's mind flashed back to the day.

Angel and Cordelia had flown over to New York City alongside Team Angel to give everyone the great news of their engagement and upcoming wedding. The Avengers had held a small party at their Compound, where Peter, Dawn, Xander, Anya, Matt and Faith had managed to come.

Baby Connor cheered on seeing Bear the puppy as Cordelia said. "Awww, looks like he likes him too."

So Cordelia put Connor down as he cutely walked to Bear the puppy who yipped at him and wagged his tail as Connor laughed and put a hand on his head. "Bear."

"Yes, his name is Bear, Connor", Faith said to him in a baby-voice as Bear licked Connor's face, getting laughs and 'awwww' from everyone in the room.

"Think they're getting along nicely", Angel said.

"What did we miss?" Willow asked as she arrived with Tara, the latter holding a kitten in her hands.

"Whoa!" Buffy's eyes widened on seeing the kitten. "Is tha-"

"No! A different one!" Willow told her as Buffy nodded.

"Right!" She shared hugs with both Witches.

"Where did you get her?" Dawn asked as she shared hugs with them, then petted the kitten's head, while Xander and Peter then shared hugs with them too.

"Oh it was a rainy night, we were sleeping, she was a stray and climbed onto our windowsill, scratching it, so we took her in", Tara summed up the story with a smile as she held the kitten up. "Meet Miss Kitty Fantastico the second."

"That is a very, very long name, you call her that all the time?" Anya asked randomly.

"Why the second?" Peter then inquired.

"Oh we had another just like this and called her Miss Kitty Fantastico, but had to give her away to another couple after a little accident", Willow said with a wince as Buffy shot her and Tara looks from her side.

Xander asked. "What kind of acc-"

Buffy gave both Witches a glare as Tara said. "We don't talk about that."

Bear was yipping still and Connor was cheering as Tara grinned and put the new Miss Kitty down, as she walked to the other two.

"Meow!"

Bear barked happily at her and ran circles as Miss Kitty simply stood, looking around at the happy puppy in what seemed like confusion.

"A baby, a pup and a kitten, great party", Spike muttered as he took a drink.

"Oh yes, the cuteness levels are overloading", Lorne nodded.

"Just don't make a mess on here", Tony added.

"They're all little children from different species, Tony, what do you expect?" Steve asked as all chuckled and Tony rolled his eyes good-naturedly.

"Yup, and like good children they're getting along", Fred said as all grinned at the scene with Bear then stopping as he licked Connor again while Miss Kitty did a 'meow' and sat down near him, tilting her head curiously, and Connor cheerfully patted both of their heads, the 3 little kids from different species getting along nicely.

Faith came out of her memories as Bear jumped and licked her face. "All right, all right, good boy, very good boy."

She picked him up and put him down as Matt came in and Bear ran to him, grasping his leg as he barked and yipped his tail, Matt kneeling and patting his head.

"Yep, go play with daddy now", Faith said as both she and Matt chuckled.

"Well, I RSVPed yes, we're going", Matt smiled as Faith leapt out of the bed, sharing a peck with Matt.

"All right, let's start preparations, come on", she walked downstairs as Matt picked up the cheerful Bear and walked down after her.

That is Chapter 1 done, not too much happened but it was to give the setup, and its approximately about 3 months after the previous story.

Next chapter will have many more developments as we get the Cangel wedding and the final big bad of this series.

This version of Electro is played by Michael Rosenbaum for...reasons.

Miss Kitty Fantastico the second was inspired by fics of boop-oop-ee-doo so thank you to them, and hope her meeting with Bear and Connor was fun and adorable.

Hope all enjoyed and see you all next time with another chapter.
