A Halloween special requested by Guest on FFN! This theme has actually been pretty popular since I started this book, but someone finally made an official request and I couldn't put it off any longer XD

There's not a whole lot of interaction between them in this chapter... I'm sorry! I really tried my best, but this really gave me a lot of trouble... I hope you enjoy the chapter though!

Also! A huge thank you to everyone that was concerned about my kitten. I have great news! She's back! She came back a few days ago completely covered in mud and a few cuts on her head and ears, she seems a little sick, but there are no big injuries as far as I can tell! I was apparently grieving and being dramatic for nothing! (Fun fact: I was originally going to name her Loki, before I knew she was a girl. This experience makes me really wish I would have kept that name.) She's sitting on me now as I'm editing; I love her enough to share her cuteness with you! I won't make it a regular habit, but I'm just so excited to have her back again that I can't help but share her picture!

Peter had to admit, he was a little confused when he arrived to the Compound the weekend before Halloween and didn't see a single decoration up. Ever since the month started, Peter had expected to see at least a couple skeletons hanging from the trees and figured they'd decorate when the holiday came closer. But here they were, five days away from Halloween and absolutely nothing.

With a frown on his face, Peter picked up his backpack and marched inside to find Mr. Stark. This was basically a crime - and Peter had to know why it was committed.

He found the man - along with the others - in the kitchen by the coffee pot, laughing at something Natasha said. His eyes brightened as he saw Peter enter, "Kid, perfect timing! Natasha just - what's wrong?"

All eyes were on Peter as he crossed his arms, "Why are there no decorations up?"

"Decorations?"

"For Halloween! It's in a few days and there's not even a real cobweb here!"

"What's Halloween?"

Peter spun around to look at Loki with wide eyes and mouth open in shock, "You don't know... Mr. Stark! We have to do a Halloween thing now! Loki doesn't know what it is!"

"We can't let trick-or-treaters come here, Peter," Steve said, smiling sympathetically. "And I don't think we could host a party on such short notice..."

"No," Tony shook his head as he placed his hands on his hips, "But we can still decorate and go out. Only if Peter helps us, though. It was your idea, no take backs - all or nothing."

Peter's eyes brightened as he nodded, "Definitely! I can get your costumes and pick out decorations!"

"Wait- That's not-" Tony attempted to reach out to stop him, but Peter was already running back out the room, calling for Thor and Loki to follow him.

The two Norse gods slowly followed after the child, both unsure of what they were getting into but happy to go along with it (Thor was happy, Loki was more... intrigued). Though both became somewhat reluctant when their destination was revealed to be back in the city and they'd have to suffer through an hour car ride together.

"Where exactly are we going, child?" Loki asked as he got into the driver's seat; Thor took his place in the passenger side as Peter hopped into the back.

"A new Halloween store that opened up in Manhattan; I went looking through it with Ned and MJ and it was amazing! Their costumes are surprisingly top notch, and their selection of decorations is huge...!"

The entire trip to the city was filled with Peter gushing about the holiday and trying to explain it as best he could... though Loki only ended up dreading it. If this child was left unchecked with a large amount of sugar, he would be able to destroy the world... Peter was already a hyper person, but add a night full of candy into the mix and he would be unstoppable.

That was just what they all needed... Hopefully Peter would decide to go back home to his aunt by then and become her problem.

With their luck however, that was most likely not going to happen...

They arrived at the store - that looked like a decorated warehouse - and Loki sighed at how excited his brother had become. Unlike Loki, Thor saw no downside to having bags of candy and was becoming very eager for this night. It was bonus points for being able to scare people without getting in trouble!

"Thor," Peter called as they entered the building, "You can push the cart, we're gonna get a lot of stuff so it'll get pretty heavy."

"Leave it to me, child!"

Loki smirked as he watched the two; he could point out that Peter had nearly the same amount of strength that Thor did and therefore didn't need someone else to push the basket - but he wasn't going to. He told himself it was because it would be funnier when Thor figured it out on his own; but watching their smiles as they walked through the store did something to the man... He'd never admit that out loud though.

"Okay, we'll start on decorations," Peter said as he looked around at the aisles, wandering with Thor close behind him and Loki dragging after.

"Was it really necessary for both of us to come with you?" Loki asked, flicking a fake skeleton head with his finger.

"Yes! Mr. Thor gets to carry the decorations, and you get to help with the costumes!"

"And what, pray tell, will you be doing?" Loki smirked as Peter paused momentarily to send him a playful glare.

"I will be organizing everything...! I'm basically in charge."

"If you say so."

Peter laughed as he led the way through the store, tossing things into the basket left and right - it was almost completely filled when they finally got to the costumes so Loki was sent to get another. The man protested at first but soon complied when Peter promised to get him a new Shakespeare book (something that Loki had recently gotten hooked on).

Slowly walking down the costume racks, Peter stared at them deep in thought. He would pull one out and look at it for some time before putting it back and moving onto the next. The process went on for quite a bit until he suddenly smiled and pulled out something light blue, then something else in a darker blue, pink, and black.

Loki got a bad feeling when Peter looked at them both with that large smile and tossed the costumes into Loki's basket before going back down the aisle and grabbing more. He would check the sizes briefly before pulling each one off, and Loki did not want to know how Peter knew what size everyone was...

"Are you going to share with us what you plan to put us in?" Loki asked, eyeing the many sparkly items in his cart.

"Nope, that's going to be a surprise!" Peter chuckled as he put another in before moving on. "It'll be fun, don't worry."

"Your type of fun being forced on us is terrifying."

"I'm not forcing it on you!" Peter laughed, "I'm simply giving you no choice but to participate."

Loki would have started to argue but shook his head instead, figuring there was no point to it when the boy was this excited. Seeing Peter laughing as the three of them went around the store was entertaining in its own way...

After they got everything they needed and checked out using one of Tony's cards, they headed back to the Compound so that they could immediately start setting up the decorations upon Peter's request.

Loki had to admit, it wasn't so bad to decorate... He wouldn't do it by his own free will, but it was still interesting to see how these Midgardians prepared to celebrate their holidays. He had witnessed a few before, but those had seemed so pure compared to this. Bright lights, stunning colors, happy music, cheerful people... He had thought all holidays were like that. But this, Loki looked at a fake skeleton with a chuckle, seemed much more sinister and far from the happiness he had come to associate with Midgardians.

Thinking back to shortly after he came to Earth, and long before he cared of the Midgardian customs, Loki could faintly remember this happening before. It was one of his first memories of Peter... The boy had on some ridiculous costume as he ran through the yard looking for Stark, tripping over nothing in his haste and giving Loki something to smile at. It reminded Loki a lot of when Thor first started wearing a cape, his brother tripping on it nearly every time he took a step. It was hilarious.

Then a thought hit him... Peter had said they were going to dress up for this holiday, did that mean they would all be wearing something ridiculous? It couldn't have been anything worse than what Thor had put him through in the past, but Peter could definitely have a chance of coming close... That thought did not bode well with him.

The days ticked by slowly, Peter coming to the Compound and isolating various Avengers to speak in private with. Loki had no idea what they were talking about because Peter didn't do that with him, only speaking with the man when they would run into each other in the halls. Loki did notice that each Avenger that Peter seemed to corner always had something different about them when the boy left... He just couldn't place what it was.

Finally, it was Halloween day.

Loki's curiosity was at its peak, and he didn't like not knowing the things happening around him. This day was eagerly awaited for all the secrets would be revealed!

"Loki," Peter called, knocking on the man's door before letting himself in, "It's time to get dressed, we're leaving in an hour!"

"Just waiting for you," The man smirked, snapping his new book closed and placing it on the desk as he stood up. He eyed the bag in Peter's hand, stepping forward as it was offered to him. "Am I finally allowed to know what you're forcing me into?"

"Yep," Peter grinned, carefully watching Loki's reaction as he gazed into the bag. He made sure to leave the door open a crack just in case he needed to make a quick getaway - he had learned his lesson very quickly when he had shown Sam his costume.

Loki's curious expression went blank as he gazed down at the light blue fabric and sparkles, blinking as he slowly looked up at Peter.

"You're kidding..."

"Nope," Peter chuckled as he rocked back on his feet. "C'mon, everyone else agreed to theirs!"

"I'm not exactly like the other Avengers, child. Surely you know this by now."

"Don't make me get Mr. Thor..."

Loki narrowed his eyes slightly, a few muscles in his body tensing. The idea of Thor knowing about this wasn't all that shocking, but the fact that Peter believed Thor had the power to force him into this costume...

"I don't think my brother-"

"He said he'd tell everyone about the time a giant stole Mjolnir and you helped him get it back."

That made Loki stiffen for a minute, the repressed memory surfacing full force in his mind. That would definitely be quite motivational.

"It'll only be for one night," Peter continued, smiling reassuringly. "Everyone else will be doing it too, so it won't be embarrassing! Even I'm going to be in something like it for my second costume!"

Taking a deep breath, Loki grabbed the costume and nodded towards the door. "Get out, I'll be finished shortly."

Peter smiled brightly as he nodded and ran out, eagerly waiting in the hall. This had been on Peter's mind for a while, and he was thankful that Loki had actually agreed to do it! He was prepared for more of a fight, having enlisted the help of Thor and a reluctant Mr. Stark. But this was awesome!

After a few minutes, Loki called for him to return to the room. Peter couldn't help the smirk on his face as he did a special knock on the door, "Loki? Do you want to build a snowman-"

The door opened suddenly, Peter stumbling back with a laugh as he looked at his friend. The laugh soon died as he blinked in awe, staring wide eyed at how perfect the costume was on Loki.

Loki's arms were crossed as he half-glared at Peter, an eyebrow raised in a way that said Loki was not amused. But that didn't matter at the moment... The fact that the Elsa dress fit him so shockingly well had Peter at a complete loss for words. Like... wow.

"That's... awesome. That's so awesome, you look amazing, Loki!"

"Go get dressed before I change my mind," Loki instructed, though a faint smirk was now pulling at his lips. Peter nodding quickly before taking off to his room, leaving Loki to find the others.

He was right to have a bad feeling about his costume earlier in the week, being put in this dress was far too much - though he would admit that he looked great in it. It was still humiliating, and he hated every second of it.

Until he reached the family room.

Loki had to hold in a laugh as he saw the other Avengers dressed in other glittery princess dresses, which instantly made himself feel better. Especially seeing Stark in the large, off-the-shoulder yellow dress that he was sure prevented the man from sitting down. Yes, Loki definitely felt much more grateful for the slim dress he was wearing.

"If you're laughing at me, Ice Queen," Tony started, "I will post pictures of you all over the internet. Everyone will see you in a dress - some will probably even use photoshop on you."

"I can do the same to you, Stark," Natasha smirked, not bothered at all by her blue pants and white baggy shirt. "All of you can actually; the kid was a genius with this. If one of you goes down, all of you go down."

Taking a good look at everyone in the room, they all had to agree that Natasha was right... Tony was Belle, Steve was Cinderella, Bruce was trying to hide in the sofa that he was a very sparkly Jane Porter... Nat was very proud of her Prince Eric costume though, and the others had yet to show themselves.

On cue, thundering footsteps down the hall drew everyone's attention as Thor made his grand entrance, standing in the doorway with his hands on his hips. Loki had to fight down another laugh; Thor looked even prouder of himself in the blue dress, black corset, and pink cape of Anna than Natasha could ever hope to in her outfit.

"Brother, friends, I am ready to go out and experience this Midgardian custom to the fullest!"

"You're gonna have to wait a little long, Point Break," Tony chuckled, "We're still waiting on the kid and pigeon."

"I heard that!" Sam's voice rang out from behind Thor, the larger man stepping out of the way as a monstrosity of red came stomping in. It took everyone a while to realize that Sam was in a mascot costume of Mushu, though he didn't seem too happy in it as he struggled to take off the head.

"Why am I in this thing? Who even sells this in a store? I am going to look stupid-" Sam finally got the head off and froze, staring at the others with wide eyes and a completely shocked face. "...You know what? Never mind. I can deal with this."

"It suits you," Steve chuckled, fighting off a laugh but failing terribly.

"Better than a dress at least..."

They all laughed and talked for a while, commenting on the similarities between their characters and personalities. An argument broke out now and then when the teasing became too much for someone's fragile ego, but it would never last long. Loki was growing tired though and getting very close to hunting down Peter to find what was keeping the boy so long...

But just as the thought crossed his mind, Peter came running into the room. "Okay, who's ready to go?"

Everyone looked to him eagerly, all curious about what his costume would be. A chorus of disappointed shouts were made once they saw the cheap suit and fedora the boy had on; though Peter only laughed as he held up his hands and shook his head.

"Don't worry, I'll change into something worse after the show!"

"Show?" Loki raised an eyebrow, carefully taking in Peter's costume, especially the velcro seams. "What show?"

"There's a competition being held at a theater that one of my classmates signed me up for, I thought it would be fun if you all came to watch! Along with the show MJ and I will be in, they have karaoke and the upstairs was turned into a haunted house! It'll be awesome!"

The group looked at each other before sighing; of course they would go with him to this competition-show-thing. And of course Tony and Loki made large bets with the others that Peter would win.

The drive into the city was... interesting. Getting everyone into the limo was slightly difficult, but then having to sit next to Tony, Bruce, and Sam was very dangerous. One could easily be smothered by Tony and Bruce's dresses, or crushed by a misplaced tail from Sam. But they all managed to survive - more or less - the trip to the theater.

There was a line of costumed people outside and wrapping around the building, a bouncer at the front door with a clipboard in his hand as he slowly let people in. Tony had the sneaking suspicion that this was more like a club than a theater... He was going to ask the kid if that was true, but Peter was already out of the car and talking with the bouncer.

The man nodded once as he gestured for Peter to go in, though his eyes widened as he got a good look at the boy's guests. The stunned silence from the crowd as the Avengers got out of the limo in the Disney Princess (and Prince) dresses almost had Bruce running back to the cover of the limo, but Thor grabbed his shoulders and pushed him forward.

Inside was slightly calmer, though there were a lot of people talking and moving. The group followed Peter as he stood on his toes to look over the heads of everyone, in search of his classmate most likely.

"Oh, there's MJ!" Peter smiled brightly, maneuvering his way through the crowd to ... him? Loki could have sworn MJ was a girl last he saw... Her hair was also a lot longer when he last saw her, had she cut it just for this night?

"Hey, nerd," MJ greeted as she looked Peter up and down with a smirk, her eyes soon moving to the Avengers behind him. She was silent for a while before chuckling, "You all look ridiculous."

"Dude...!" Ned frowned at her, "You can't just call the Avengers ridiculous...!"

"I just did."

Loki drowned out the two of them arguing as he looked around, taking in his surroundings. It wasn't overly crowded, thankfully, but it was heavily populated. There was a stage on the other side of the room with multiple rows of chairs in front, people already starting to take their seats. Colored lights flashed in time with the background music, two things that would normally send Peter's senses reeling. Taking a closer look at the boy, Loki noted with interest the small earbuds he had; a prototype of Stark's new sound muffling tech. He really hoped they would work well for him tonight...

A voice called for all the performers to head back stage, Peter smiling wide as he and MJ left the group. Figuring that the show would be starting soon, the Avengers went to take their seats in front of the stage - front row, thanks to Stark and his money.

It was fun to watch Stark, Banner, and Rogers struggling to sit in their dresses, Loki almost laughed when Stark's flipped up and almost buried him in the golden fabric and hoop skirt. But the man must not have liked Loki's quiet snickers because he stopped trying to sit on the end of the aisle and went to take the seat right next to Loki, effectively burying him beneath the same fabric and hoops that Stark was suffering from.

It became a game after that - trying to see who could bury who first. Loki was sure that Peter would hate himself for missing it later on...

They were forced to settle down soon afterward though (Tony declaring himself the winner for taking out two at once - himself and Nat) when the curtain on the stage started to lift, showing an incredibly dramatic and gold setting with half of a fake jet. When the jet door opened and MJ stepped out in a cover of fog, Loki could hardly believe that this was the same teenager he had known before... The normally bored and uncaring girl going all out with her show - Loki could hear Peter cheering in the side of the stage. To think she was hiding all of this dramatic talent beneath her cold exterior, Loki definitely liked her.

The cheering of the crowd almost became too much when she went off to the side and pulled cash out of her pockets, suddenly Peter was much more noticeable as she threw the money over him. Peter laughed as he played along with her, though there was a very dark blush spreading across his cheeks.

When her show ended and gold confetti exploded from somewhere above them, the people's excited cheers became much louder than before - though Peter still seemed to be the loudest.

It was definitely interesting to watch, Loki had to admit. He had never found these sorts of events enjoyable, but this Midgardian one was different from the ones on other worlds... It could be a treat in rare doses.

There was a small break after MJ and her dance crew had left the stage, the staff having to clean everything up and roll in the next set - which Loki assumed was Peter's. When the boy peeked his head out from behind the curtain to look at them, the man couldn't help but raise a brow at the nervous expression Peter wore. It didn't look like the kind of nerves one got from stage fright... But what else would Peter have to be nervous of?

The boy gave him a small smile and thumbs up, Loki nodding in return, before he ducked back behind the curtain. A few minutes later, it rose to reveal a mostly empty stage - save for the large cardboard cutout in the middle.

Loki could help but frown slightly when Peter started twirling around on the stage to the peaceful but boring song. Surely the boy didn't think he'd win just from that? When he wanted to, Peter's dramatic and pure extra-ness could rival that of even himself and Stark. But this... Loki and Tony both avoided Sam's smug gaze through his suit, all three knowing that Peter had a real chance of losing - along with the money the two men were betting on him.

When Peter ducked behind a group of umbrellas, the small and almost pitying cheers from the crowd quieted down - just before picking up again as the song changed and a group of men came on the stage to start dancing. The cutout lifted into the air seconds before the umbrellas lifted and Peter came marching back onto the stage.

Even as the crowd roared, all of the Avengers were silent - forced into silence by their shock. Peter stood in the center of the stage and danced with the most confidence anyone had ever seen - all while wearing a leather bodysuit and fishnet stockings.

Thor seemed to be the first one to snap out of his shock, soon cheering just as loudly with the rest of the crowd, the rest of the team slowly following suit. It was then that Loki could hold back his laugh no more, the chuckle building louder as he shook his head slightly. There was no way Peter was losing this, he should have known better.

A wild smirk played on Peter's lips that Loki knew all too well, watching as the boy went over and started dancing on the side of the stage next to MJ. The cheering grew as she started dancing along with him for a second before Peter left and reached down to splash water from the floor-

Water?

Loki blinked before narrowing his eyes, making sure he truly did see water fly from Peter's hand. He didn't have to search long for his answer though, seconds later a rain machine turned on just over Peter. Loki almost felt like sending a smirk towards Sam because there was absolutely no way that Peter would be losing this contest, but he kept his eyes on the boy in fear of missing the next change of scene.

Water splashed across the stage as Peter and his male backup dancers moved in the rainfall, Peter's wig slowly starting to stick to his face as he jumped and turned and flipped in the water. When the sparkler machine turned on behind them, Loki finally managed to glance over at Sam to see that the man had taken his costume head off and was staring with wide eyes and mouth open at the show. He would be losing quite a few dollars that night.

After kneeling on the stage and making sure he could get himself as wet as possible, Peter ended his performance with a flip. Loki cringed slightly at how hard he landed on his back, making a mental note to ask about that later.

All of the Avengers, as well as the rest of the theater, stood up to cheer their boy on as he stood up and took a dramatic bow next to the edge of the stage. The cheering of the crowd was nearly deafening, but Peter smiled widely as he waved to everyone before jogging backstage, sending a mischievous grin to Loki before he disappeared.

There were a few other competitors afterward, but none of them could really compare with Peter. They seemed to know that too; often resulting in them trying too hard or not enough.

The time for the judgment couldn't have come soon enough, all of the contenders standing along the stage - Peter still in his leather and fishnets but with the added accessory of a towel around his neck.

It came as no surprise when the judge announced Peter the winner, handing him a large studded belt as a reward. Peter held it high above his head, grinning brightly as his adoring fans screamed their praise.

"He gets that from my influence," Tony smirked as he leaned over to Loki, chuckling a bit.

"The adoring fans?" Loki glanced at him before smirking as well, giving a small shrug. "I'll give you that; but he gets his taste for dramatics and winning side from me."

Tony looked like he was about to argue, but a loud scream caught everyone's attention and made them look to the stage just in time to see Peter running off it, a horde of fans chasing after him. It took a second for that scene to register with everyone, but once it did, even Loki couldn't hold back his laugh.

He could definitely get used to this holiday.

A/N: I was playing around with so many different ideas for this chapter, you have no idea! I thought of a haunted house, costume contests, festivals, everything! But then I got a few new comments on an old story I wrote, The Dancing Spider... Basically it's Peter and MJ doing the Lip Sync Battle at their school and the Avengers sneaking in to watch. I got back into watching Tom and Z preform and I couldn't resist. I had to do it, I hope you don't mind!

Question of the day! If you're dressing up, what/who will you be? A few months ago I had hoped to be Natasha, but I cut and dyed my hair again so that's a nope... I'm not going out tonight, but I'll probably get into cosplay and make a few videos.

This was me last year! I never wore this anywhere, not even a convention, but I'm still pretty proud of it!

.

.

.

The team - along with MJ and Ned - had a very full night after Peter escaped his fans... The group had gone upstairs to the haunt house for fun, Sam trying to redeem himself by claiming the first one to scream had to buy their food that night.

Poor man... He didn't stand a chance.

Neither did the zombie actor that got hit by his tail.

Peter, who was disappointingly unaffected by the jump scares thanks to his spidey-sense, never thought he would see the day when the Avengers would scream in fear of actors. But here they were! Bruce had wisely made the decision to wait for them all downstairs, which everyone was soon thankful for. For a cheap theater like this, their haunted house was amazingly good. So good that Peter had to threaten to become a human shield for the actors to keep Loki from stabbing them - Loki and Tony were not thrilled by that.

Leaving the theater building with Tony (by default since Thor didn't actually have money) buying dinner, Peter cringed slightly and wrapped his arms around himself. His leather body suit and the cool Autumn air did not mix well... Especially when he was still slightly wet from earlier. "It got cold...!"

The group all stiffened for a second, glancing around each other with wide eyes as Loki gave a small chuckle.

"The cold never bothered me anyway," He smirked, looking down at Peter with mischievous eyes. Though even Loki couldn't hold back his shocked laughter as Thor popped up behind him with hopeful eyes and a large grin.

"Do you want to build a snowman?"
