This year we're doing crossovers for all seven days of Halloween, which means a couple of "repeats" for fandoms, but I think it will be a whole lot of fun. At the very least, I hope I can do something that I enjoy with each of these crossovers.

Day 1 (Oct. 25th)- Teen Titans and X-Men

Day 2 (Oct. 26th)- Ducktales and Big Hero 6

Day 3 (Oct. 27th)- The Good Place and Zoey's Extraordinary Playlist

Day 4 (Oct. 28th)- Teen Titans and The Owl House

Day 5 (Oct. 29th)- Gravity Falls and Lilo and Stitch

Day 6 (Oct. 30th)- Gravity Falls and The Owl House

Day 7 (Oct. 31st)- Gravity Falls and Over The Garden Wall

Hope you enjoy as much as I did!

A friend once requested a BH6 and Ducktales crossover, since those are some of the fandoms I've written the most for. This is the only way I could think to do it. An alternate version of what happened to the Triplets in Let's Get Dangerous, so if you haven't seen that much of Ducktales Season three then you probably should before reading this. Mentions the events of Portal Enemy and off-handedly makes fun of BH6 Season three with no season three spoilers.

When Dr. Bulba threw Huey, Dewey, and Louie through the portal the transformation was immediate and gruesome. Their bodies stretched and their skin turned soft and raw, like uncooked meat. Their legs were wobbly and bare, they hadn't needed pants before but now they had the desperate urge to cover themselves. Like Adam and Eve after the original sin. Huey looked around, desperate for answers while Louie melted into the fetal position on the ground, and Dewey stared at his reflection in a window.

"Hey," GoGo said, shaking Hiro awake from a mid-homework nap, "we need to go. Now."

"Why, what's wrong? What happened?"

"A portal opened up in the sky and dumped three half-naked preteens in the middle of downtown San Fransokyo. It feels like we should check up on that. Honey Lemon and Wasabi are already on their way over there."

"Do you think it's Project Silent Sparrow?" Hiro asked, his eyebrows furrowing in concern. Anything having to do with portals was bad news in his opinion. Sirque had recently tried to restart the project and Callahan had nearly succeeded in tearing the world apart with Silent Sparrow.

"We're not sure, but whatever it is, those kids probably need medical attention." That caught Baymax's attention, and Hiro quickly stood.

"Alright, let's go."

Huey was still standing when the superheroes came, though Dewey had taken a seat to console his weeping younger brother.

"Heroes," He murmured in awe as he looked at the taller beings, still fleshy and grotesque but confident in their horrid bodies.

"Hi," the lady with long strawberry blond hair said, "We got you some pants."

"And blankets," the other, a dark-skinned man with dreadlocks, said, holding out his offering a bit nervously as if he expected them to attack. Both of the heroes glanced sympathetically at Louie, but Louie hadn't noticed them yet, still in the middle of his panic attack.

"We're not from here," Huey said as he put on the ill-fitting pants.

The lady nodded, seeming like she trusted him.

"And I don't know how to get back," Huey admitted, panic rising up inside of him for the first time. He had to rescue his brothers, he had to get them back to their reality. This world was abnormal, unfamiliar, and scary. Like they'd entered into a horror movie.

"We can help. Our friends are on their way and then we'll get you to a safe place," the man said, draping a blanket over Louie as he continued to shudder and cry. Dewey stood up, pulling on the pants. He didn't fully trust these guys and stood defensively in front of Louie.

"We don't need your help. Our friends are going to save us."

"Dewey," Huey said, "These guys can help until our friends are able to figure something out." He glanced at Louie and Dewey understood. They needed to get Louie somewhere safe until they could make it home.

Five more armored heroes landed next to them. One looked like a comic book cryptid, two looked like robots, and two looked like the other fleshy beasts, both only slightly taller than what Huey and his brothers now stood at.

The one in purple moved towards Huey, studying him.

"Where'd you come from?" Purple guy asked.

"It's hard to explain…"

The red robot reached down and picked up Louie. Louie didn't even seem to notice, a bit disassociated at this point, but Dewey nearly went ballistic.

"Hey! You can't do that! That's my brother, put him down!" Dewey charged the robot and kicked it, fire burning in his eyes until the lady in yellow dragged him back.

"Calm down, pipsqueak. Baymax is a personal healthcare assistant. He'll help your brother."

"Dewey, we need help," Huey said quietly, "and these guys are superheroes."

"Fine," Dewey muttered, but he kept an eye on Louie.

Without seeing much more of an option, they took the three kids to their lair. Huey was the most level-headed of them, at least by appearance. Dewey seemed to believe he could fight his way out of any scenario, despite being a scrawny 12-year-old. Louie had yet to say anything but was, at least, now wearing pants.

"Now scanning," Baymax announced when they were all safe in the lair. The robot assessed the rag-tag crew and then turned to Hiro.

"They do not belong here."

"What do you mean?" Hiro asked. They were just kids, scared but trying to be brave, wrapped up in blankets and clinging to each other to feel even an ounce of comfort. Hiro knew what it felt like to be young, afraid, and out of place.

"They are not from this reality," Baymax clarified.

Fred gasped at that, "This is the coolest thing that has ever happened! Best Halloween EVER!"

"Freddie, it's not even Halloween, it's barely October," Honey Lemon pointed out.

"Close enough! Invaders from another reality? That sounds like an old Halloween sci-fi movie to me. My dad has tons of them."

"Our lives aren't some movie or tv show," Huey said, getting a little angry for the first time. He wanted to go home. He wanted to get his brothers home.

"Of course not," Hiro said hastily, "we're going to figure it out."

"We are in a tv show," Louie mumbled, seemingly aware of the conversation for the first time, though still a little spacey.

Huey held Louie a little closer, "Hey, no, it's okay. We're okay. I'm here. I'm going to get us home."

"We're in a tv show," Louie repeated insistently, "that machine-"

"The ramrod," Huey supplied.

"-It takes things from fictional worlds, right? Alternate realities! This time, the alternate reality took us instead."

"That… Makes a lot of sense, actually. And now we're stuck in these bodies in this superhero show…" Huey got up, thoughtful at this new revelation.

"What do you mean, these bodies?" Hiro asked.

"What do you mean, this superhero show?" Wasabi asked.

"I knew it," Fred said, smirking with great satisfaction.

"This is a show and we're the main characters and this is our Halloween special. It's a crossover."

"Your eyes are crossed-over," GoGo snapped.

Honey Lemon cringed, "GoGo, dear. Your comebacks are really bad."

"That's because of her character archetype, tough and scary, secretly soft and not always the best at words. If the show ever sold out they'd probably rely on these cheesy, bare-bones character traits for easy, dumb jokes. And then we'd probably get canceled."

"Like you being a slovenly, gullible glutton? I could see them making a LOT of jokes about that," GoGo shot back.

"Okay, I take it back. You're good with words. You're tough and hurtful and we all have depth and complexity as characters that the showrunners ignore-"

"Shut up," Wasabi blurted, startling everyone. Suddenly all eyes were on him.

"I don't think enough people are freaking out about the fact that other realities are real."

"You didn't believe in other realities?" Fred asked, "That's pretty solipsist of you."

"I'm not a solipsist. I just didn't think we would deal with the ramifications of alternate realities in my lifetime, Fredrick."

"Must be a lot to wrap your head around," Fred nodded sympathetically.

"We've fought actual monsters, Wesley, woman up," GoGo said.

"Your real name is Wesley?" Honey Lemon asked.

"Yes? Maybe? I don't know what is real anymore," Wasabi lamented.

"We've fought actual monsters," Huey mumbled to his brothers, "we're smarter than the smarties, tougher than the toughies, sharper than the sharpies. We'll get out of this." He was trying to give his brothers a pep talk, but Dewey wasn't listening and Louie looked unconvinced.

"We're twelve," Louie pointed out.

"And we've been through worse than this."

Louie pulled at his fleshy cheeks, his face contorting, "Worse than this? Really?"

Huey squirmed in discomfort.

Dewey had been humming, his tongue stuck out in concentration as he drew something on paper the heroes had provided. Now he held out his drawing to GoGo, like a little kid presenting a crayon masterpiece to a babysitter.

"That's how we're supposed to look."

It was an amateur drawing but one thing was obvious, these three were not humans.

GoGo stepped away, showing the others the drawing.

"Are they aliens?" GoGo whispered.

"Are we aliens?" Fred countered.

"We're probably aliens to them," Wasabi said, struggling to adjust his worldview to this new realization.

"No one is an alien," Hiro said, "They're just kids who need help getting home." He turned around to address Huey, Dewey, and Louie and saw that the trio was just… Gone.

"Basemax, where did they go?" Hiro demanded. Basemax brought up security footage, showing the boys in their seats one moment and then, in a blink, gone. Hiro reached it several times.

"They were raptured," Wasabi said, his eyes wide.

"Oh, you don't believe in alternate realities but you believe in the rapture," Fred said with an eyeroll.

"I don't know what I believe in, anymore, but it makes just as much sense as alternate realities and aliens!"

GoGo stared at the piece of paper.

"Whatever just happened, they're home now," she said.

"Maybe we should all go home," Honey Lemon suggested timidly, "And just… Forget that this happened."

"Yep," Wasabi agreed, "Our reality is intact, there are no alternate realities, and we're not in a tv show."

"You're just in denial," Fred complained as Honey Lemon, Wasabi, and GoGo left.

"Let them go," Hiro said with a sigh, "Today was weird."

"But it was real. And they're going to pretend it isn't real!" Fred crossed his arms in disappointment.

"Until we understand what happened it might be best to act like nothing did. It would certainly be easier, I don't blame them for wanting things to be easier. I'm going to do more research."

"Do you want to come back to my house and watch old sci-fi horror movies?" Fred asked, not wanting to leave Hiro alone after everything that had just happened. After all, Hiro was just a kid too. Tadashi would want someone checking on his little brother.

"Yeah, sure." Maybe a distraction would be good for a bit. Maybe it would help him see things from a different angle.

"Kind of a weird ending compared to our last Halloween special, but it opened the door for a really interesting arc, maybe even a television movie, if the writers ever get the chance to pursue it more…"

"Fred, this isn't a Halloween Special."

"You can't prove that."

"I don't think I can prove anything anymore. Reality is no longer as real as I thought it was."

Back in St. Canard, Huey Dewey, and Louie made a silent agreement not to bring up the strange creatures they had become, though it would haunt them for the next few years. Instead, they hugged each other and their friends and family, eager to go home and settle back into their reality. For all their unanswered questions about F.O.W.L. and the ramrod, right now it was enough to be back together and in one piece.
