A/N: After a very long day of getting my teeth filled in, the time has finally come. For all of you fans of my crossover series, I have present you my new Scooby-Doo/Pokémon story; The Island of Mayhem! This is actually based off the live-action 2002 movie of Scooby-Doo. It took me a while to find the actors to imagine the XY Gang as if they were in the movie. Here they are:

Francis Ryan Lim as Ash Ketchum

Kyla Deaver as Serena

Jacob Hopkins as Clemont

Sunnie Pelant

Now, without further ado, let us begin the story!

One Day Ago

12:00

Spooky Island was a place where your worst fears come to life, or so Ash was told. Honestly, the spooky house at the carnivals back in Kanto were more frightening than some of the attractions on the island. The only thing that really did scare him were the college students.

Was ever he glad that the Regions gave kids his age the chance to not attend school because he can never imagine turning out like those people; being label as stereotypes by people who don't even know you, then being cooped up from the world, never having a chance to go out and explore? Not to mention not having his best friends by his side.

Yeah, he likes being a Region kid.

After watching another group of drunk students walk away from the stand he was working at as they spoke a bunch of ridiculous things that he didn't even bother to understand, he turned to his little partner beside him. "So, how much you wanna bet they're going to be waking up with a killer headache in the morning?"

The large yellow mouse gave him a look like he was being very thoughtful about it before he held up his five little paws. "Pikachu!"

This made the raven-haired boy laugh as he put the money he'd received from the last customers away into the cash register. Another successful day on Spooky Island.

"Is today finally over?" A high-pitch voice whines from behind him, making Ash turn around to see one of his best friends, Bonnie, walking over to him, looking completely miserable with her oversized hula headdress on her head. Ash couldn't blame her for being miserable since that hat did look ridiculous on her.

Ash took a look at the digital clock right beside him. Soon enough, a glowing green 12:00 A.M. appeared on it.

"Yeah, our shift's over." Bonnie instantly look relieved.

"Finally!" She quickly took off that ridiculous hat and set it down on the counter to be forgotten forever. "Do you know what's it like to wear something like that on your head all day while working in the room full of dish dryers? The kitchen was way cooler!"

"Well, maybe you should have thoughto before you decided to eat three bowls of frosting!" Ash winced when he heard the familiar puberty-pitched voice before he turned and saw his other best friends Clemont, who was giving his little sister a hard glare from behind his glasses, and Serena, wearing the same hat as Bonnie and sharing the same awkward glance with him, walk out from said kitchen, both of their hands covered in flour.

Ash remembered that incident a few days ago; originally, it was Bonnie and Serena in charge of the kitchen while Clemont was the one attending the dishes but it changed when the older sibling caught his sister trying to sneak in some bowls of frosting. Since then, Clemont's been helping Serena in the kitchen while Bonnie's the one stuck with the dishes.

The young girl pouted. "It's not my fault that frosting tastes so good!"

"Bonnie, that's stuff bad for your teeth!" Clemont argues. "Do you think I want to explain to dad why you have so many cavities in them?"

While the two siblings continue their bickering Serena took the moment to walk right next to Ash and joined him by leaning her back against the counter like him.

"Can you really believe it only took them three weeks before they start to fight again?" She asks with mirth shining in her blue eyes. It made Ash chuckle under his breath.

"Yeah, I really thought they were going to explode on the first five days," he turns his attention towards the yellow mouse. "Right, Pikachu?"

"Pikachu!" The Pokémon cried cheerfully, making the two children laugh.

Their laughter was cut short when they saw their boss coming over to their stand and siblings were still arguing.

"Clemont! Bonnie!" Serena whispers loudly to them, making the siblings stop their little fight before turning their attention to their upcoming boss.

"Mr. Mondavarious!" Clemont greeted, his small fight with his sister completely forgotten as he and his friends stood in front of the stand to greet the owner of Spooky Island.

"Ash! Serena! Bonnie and Clemont!" Emile Mondavarious greeted cheerfully once he reached them. "How are you children fairing on this fine evening?"

"The hat sucks," Bonnie's deadpan voice left an awkward silence in the air. Thank goodness it was broken by Mondavarious chuckling.

"Oh, your sister still has that wonderful sense of humor of hers," this made Clemont give him a tight smile before shooting a glare in his sister's direction while the owner of Spooky Island turns his attention to Ash. "Now, my dear boy, how was today's business?"

"Uh, right," he opens the cash register and quickly counts the money within. "Well, we managed to make it up to a hundred dollars today and, added with the rest of the week, I say we earned at least $700."

Everyone around him gave him jaw-dropped looks.

"What? You guys are looking at me like I can't count." The raven-haired boy joked, making them all shake out of their trance.

"Wonderful job then, Ash," Mondavarious praised as he reached into his pocket, pulling four stacks of fifty dollar bills. "You and your friends, once again, have earned these."

"Yay!" Bonnie cheered as they were all handed their respective stacks. "Now I can finally get that new candy gun!"

From behind her shoulders, two creatures propped themselves up to see the stack. One of them was another strange-looking mouse like Pikachu only it was smaller and orange. The other one was a strange, green blob with a round head, one eye, and red gem on its leaf-like body. They stared at the stack before they let out their own cheers.

"Bonnie, may I remind what this money is actually for," Clemont shifts his eyes towards Ash, who suddenly has this blank look on his face, before turning his attention back to his little sister.

The eight-year old's face turns into a frown once she realizes how selfish she must have sounded. "Right, sorry Ash..."

Ash's face then broke back into his usually, smiling face like nothing had ever happened. "It's cool, Bonnie," he collects the rest of the money from his friends then heading to the back of the room where a money jar with a red line going near the top.

He unstraps the dollars and lets them fall freely into the jar, where all the other money they've earned were placed. "And we're..."

His face falls once he realizes the jar wasn't even half full. "Nowhere close to getting the amount that we want."

This made his friend's faces fall and Emile gives them a look of sympathy. "I'm sorry, I'm doing my absolute best to get you all the money that you need. But even if my feelings do play a part in this, I'm still the owner of an amusement park. If I could, I would have given you all the money already."

"We get it, Emile," Ash cuts in before the owner could continue. "You're the boss; you've got more responsibilities than any of us and you need to look after the park, not to mention all that stuff about taxes. No need to explain why you can't just single handily gives us the money."

The poor boy looked tired beyond belief; he was very pale, he had dark bags under his eyes, and his brown eyes that were once full of energy now looked exhausted. It was unlike the free-spirited boy that his friends knew and it made them want to do something about it. So when they gave the owner of Spooky Island certain looks, Emile had to proceed.

"But I do have some wonderful news, though," his words manages to catch Ash's attention. "Since this is your last night putting up the signs that specifically tell the college students to stay away from the Spooky Island castle in the forest, I've decided to add your work efforts over these past three weeks into your paychecks!"

This made them all smile in excitement. "Awesome!" Serena gushed.

"Wait," Bonnie's face turns into a frown as she regards Mondavarious with narrow eyes. "The college students tore down the signs again? After three weeks, they still didn't get the hint?"

If she was trying to make Mondavarious nervous it was working, the poor man was shifting his eyes back and forth between them all. He was saved, thankfully, by Clemont scolding his younger sister.

"Bonnie, come on," the glasses-wearing boy sighs. "You know how these college students can be; remember our first day on Spooky Island? These people don't know common sense even if it hit them on the head."

It made Bonnie pout even more while crossing her little arms over her chest. Clemont once again sighs. "I'm really sorry about her, Mr. Mondavarious."

"Oh, that's alright my dear boy," the older man waves him off. "She is a very bright girl for her age, you should be proud that she has your level of intelligence."

Bonnie looked like she wanted to make a remark but a look from Serena silenced her.

"Now then," Emile claps his hands together. "Chop, chop with the four of you. You're already running late and I want you all to get a good night's sleep. I will see you all in the morning." With that, he left the kids to their own devices.

Serena puts her hat down. "Well, into the woods we go."

As his friends begin to head to the restroom to change into their regular clothes, a small "Pika-pi" caught his attention. He turns his head around to see Pikachu holding a flare gun that seems to be a little too big for his paws.

He had to bite back a laugh. "Seriously, Pikachu?" During their first night at Spooky Island, Mondavarious has provided them with walk-talkies and flare guns in case they found themselves lost in the woods of Spooky Island. After spending three weeks of doing the job at night, they have agreed to carry only three walk-talkies and leave the flare gun behind.

But for some reason the Pokémon seem pretty stubborn on having them carry the flare gun at all times since the three of them usually stay behind back at the resort, Squishy especially. Now it seems like it's Pikachu's turn to convince them.

Realizing that the Mouse Pokémon wasn't going to budge anytime soon and the fact this is the last night they're going into the woods, Ash relented and took the flare gun.

"There? You happy now?" Pikachu nodded and it made Ash shake his head.

"Be back in half-an-hour," he tells his partner before following after his friends to the restroom.

The walk to the Spooky Island Castle was treacherous to those who never exercise before. To Clemont, it was absolute torture. Added to the facts he's carrying tons of wooden signs and wearing a jumpsuit in the middle of May was enough of an excuse to collapse in the middle of walking up a small hill.

"I can't go on!" he cries out dramatically. "Why is it even so hot at night?! May is the time of the month where Australia is supposed to be cool at night!"

His friends, especially his sister, gave him unamused looks. "Clemont, the hill is not even that high."

"It doesn't change the fact that it's still hot out," he shifts his attention to the raven-haired boy. "Ash, back me up. Come on! Aren't you exhausted too?"

"Well, yeah," Ash admits. "But I have good enough reason for it; I'm sick. You're just being your usual self, Clemont."

Clemont gave him a look. "Thanks for the support, Ash," he tells him sarcastically before he picks up the signs he had previously dropped and follows his friends up the hill.

After watching her friends and older brother get to work on placing the signs around the open area of the woods that just so happen to be close to the Spooky Island Castle, Bonnie turns her head to look at something else. She knows that something weird was going on and she's been around this area enough to know when the weird stuff happens. All she needs to do is listen closely and...

Bingo.

"Race you guys!" She yells at them from over her shoulder and before they could react, Bonnie's already running into a deeper part of the woods in a blink of an eye.

"B-Bonnie!" Clemont quickly drops the signs he's been holding to go after his sister. He was followed by Ash and Serena, wondering what had gotten into the young girl.

Bonnie was laughing as she ran through the woods, her brother and friends trailing behind her. Despite knowing that there might be something big going she decided to laugh a little at the fact she's making her older brother, who's too lazy to even walk for a bit, run almost as fast as Ash. Too bad her fun was ruined when Clemont somehow caught up to her.

"Bonnie, what are you doing?!" he demands when the rest of their friends caught up. "You know we're not supposed to be in this part of the woods. We could get in serious in trouble for this!"

"Can you please stop lecturing me for one second and listen?!" The little girl snaps, making them all speechless since Bonnie never tends to lose her temper like this. Before they could ask what she meant by that they finally heard it.

A shriek.

Not like the kind someone would use when they see something scary and be overdramatic about it - like in those really bad horror movies in the 60s. No, it was something else entirely. Something that was not human. But they knew it also wasn't an animal or a Pokémon they had ever heard before.

The fact that they didn't know what type of creature that's out here with them was beginning to scare them all. All but one, though. Once she sees them looking at their surroundings, indicating that they have heard the same thing, Bonnie's face broke into a huge grin as she bounces on her heels.

"See?! I told you!" She gloats, not noticing their scared faces. "I knew something weird was going! Even the college students aren't stupid enough to keep doing the same thing over and over again! Mondavarious wanted us to come out here every night because he's hiding something!"

"Bonnie..." Clemont couldn't ignore the fact that what his sister said actually made sense - even he found it a little strange after the first week - but he's also aware that they might be walking into something pretty big if Mondavarious didn't want them to be around it. The fact the shriek from before sounded closer only scared him more.

"Bonnie, I think we need to head back," he grabs his little sister's hands and begins to back away from the place they were already on, Ash and Serena already ahead of him since they were the first ones to back up. "Right now."

"What?!" Bonnie pulled back to stop her brother from going any further. "But shouldn't we be looking around to see what's happening?"

"Bonnie, did that noise sound like anything you've ever heard before?" this made the girl falter slightly. "Exactly! Personally, I want to figure things out too but do you remember what that crazy Chicken Man said? We shouldn't even be this far in the woods, anyway."

Seeing the young girl's downhearted look, Serena decided to step in. "Maybe we should just head back to the resort and figure this out in the morning. Because I don't think whatever these things are come out during the day."

It seemed good enough for Bonnie, although she still looked a bit disappointed. But it was good enough for the older children because they could finally leave the creepy area.

That was until they heard another shriek nearby. Only this time it sounded right on top of them.

They whip their heads around only to find their hearts stopping when they see a pair of glowing green eyes within a patch of shrubbery, blocking their way back to the resort. If it weren't for the fact they could hear breathing from the bushes they wouldn't have been so scared as they were now.

"Guys?" Ash whispers, making sure his voice was low enough so that the thing couldn't react as he quickly turns to his friends to make sure that what he's seeing was real.

But seeing the look on their faces instantly told him that it wasn't some hallucination caused by a sick daze and they were actually in the presences of a creature that they've never seen before.

They started to back away from it, slowly diminishing their chances of running back to the safety of the resort but they didn't care at the moment; their path was blocked by a monster after all. Their eyes had never left the green orbs because they were afraid that if they were to look away, something bad will happen.

They only began to pick up the pace when something popped out of the bushes.

Ash hadn't intentionally brought himself to lag behind in what seemed to be a sadistic race - although he probably would have done it anyway since he would rather have him get taken first - but he guess that's what happens when he's sick; his lung burned with every step he took, his legs were aching to the point it felt like they were being pressed down by a pile of rocks, not to mention his vision was fading due to the intense pounding in his head so he couldn't fully see where he was going. But he couldn't bring himself to stop. Not when there was something dangerous coming after them.

Hearing the sounds of Serena panting with Clemont and Bonnie's whimpering ahead assured him that he hadn't strayed from his friends and kept him running in the direction he's currently running in. He didn't know what would happen if he was separated from his friends; there was the chance of the monster going after him or it might decide to still go after them instead. Which was why he decided to keep close to his friends.

But it didn't change the fact his illness was making it very difficult for him.

He should remember that he's supposed to look around when he's running like this and not rely only on his hearing to keep up with his friends, but his head was pounding to the point he was seeing black spots in his vision. Maybe he should have made more of an effort to try and see where he was going, that way he could have avoided tripping on something before face-planting on the ground hard.

"Ash!" He heard his friends shout ahead of him as he tries to lift himself back up but his legs were practically dying at this point. Despite every instinct telling him to run when there's something chasing them, he couldn't help but rest on the wooden floor below him - doesn't that mean they had almost crossed the old wooden bridge that leads to the cliffs? He didn't know anymore. Why did he have to be sick now out of all times?

"Come on, Ash!" Three pairs of arms were suddenly on him and if he didn't recognize them as his friends and not the monster he would have been throwing punches by now. He let them lift him up to his feet and guide him back into running because he knew that they definitely need to keep moving.

When he felt his walkie-talkie slip from his pocket he knew he should have said something to his friends or, at least, run back to try and get it. But his sick-filled thoughts made him think none of it. It wasn't like he was going to need it anyway, right? Clemont and Serena already have their own so it shouldn't matter.

His brain managed to clear up the fog enough for him to realize that he and his friends are in a dire situation and began to run on his own again, making his friends loosen their grips on him. He didn't know what possessed him at the time but he thought they were all going to run down the right path but his friends kept going straight.

He was able to correct his mistake and quickly followed behind his friends. Right on time too because when he turned his head to look back the thing was still coming their way.

When will it ever give up?

Ash was neck-to-neck with Serena when he finally noticed his vision clearing up, which was good because he didn't want to keep relying on his hearing anymore after that mess on the bridge. But stopped when Serena's arm suddenly snatched his wrist. What was she doing?

It was then he looked ahead and he was glad that Serena stopped him in time.

It turns out that it wasn't Ash's vision that was clearing up but it was actually the light from the moon which they couldn't see before due to the dense area of trees. But now they had managed to run out of the forest and into a large clearing. Ahead of them was the drop off of a cliff. They were near the top of Spooky Island's mountains.

The monster had led them straight to a cliff.

"Oh, you've got to be kidding me!" Ash heard Clemont groaned and he couldn't help but agreed. One of the worst things that could happen when being chased by a scary monster was getting caught in a dead end during the middle of the chase.

They all turned on their heels and tried to head the monster off but they stopped when they saw the same pair of glowing green eyes in the bushes ahead of them.

It had them cornered.

Ash could practically feel Serena's hand squeezing the life of his wrist and wished he could return the favor as the four of them backed up.

They knew they shouldn't be backing up when they're at a cliff but their fear was clouding their senses. They had nowhere to go and the only alternatives were to face the monster head-on without any Pokémon or jump off the cliff and hope for the best.

They really wished life didn't give them those types of choices.

"Go away!" Bonnie tries to drive the monster away with her hand, the other one gripping her brother's tightly. "Nobody likes you! Shoo!"

Her words only made the green eyes narrowed.

"Please, no!" Ash heard Serena sobbed and he could see why; when he turned to look over his shoulder his eyes widen when he saw that they were right at the edge of the cliff - how did they get that far in such a short amount of time? - and the monster was still pretty determined to keep pursuing them.

"Get back!" Ash found himself joining in on the yelling match, but it did nothing and only brought the eyes closer. "No!"

Then it jumped out the bushes.

The reaction was immediate; Bonnie ended up backing into an old sign that said DANGER but the old thing broke when she put her weight into it. She ended up falling back, taking Clemont down with her. Serena tried to save them by grabbing Clemont's hand by she ended up slipping, taking Ash with her since he was holding onto her.

They all screamed as they fell to their demise...

But then Ash somehow managed to get a hold of an old vine and their screams suddenly stopped.

Ash didn't know how he did it but it didn't matter to him at the moment as he tightens his grip on Serena's wrist. While he didn't exactly have a good grip on the vine he had a better grip on Serena so as long as they all don't let go of each other they'll be fine.

Then he heard the screech from above and realized that they weren't out of the woods yet.

"Bonnie, don't you dare let go!" Clemont's voice made him forget about the screech and look down to see Bonnie at the end of their little Aipom chain. The poor girl had never looked so strained as held onto her older brother's arm for her life.

Ash could understand her strained because he was the link that was keeping them all from falling. It was the combined forces of his friends' weight, the fact he didn't have a good grip on the vine, and his pounding headache from his illness that began to take its toll on him; his vision was darkening once again, his lungs were burning with each breath he took, and he felt like his arms were ready to give out at any second.

But he wouldn't dare let go, not when his friends' lives were depending on him.

"A-Ash?" Serena called out hesitantly, she and the siblings looking at something fearfully above him. Ash hesitantly cranked his head up and found a terrifying sight to behold.

The monster was looking down at them from the ledge, its horrible green eyes were glowing with malevolence once it realized they really did had nowhere so their only options were to let go and hope for the best or let the monster pull them up and have it take them away to its dark lair where nobody will find them again.

When he turned to look down at his friends, Ash already knew what his decision was right when he saw the monster.

So when he turned to see the monster preparing to use its large hand to grab them, he did the only thing he could do.

He let go.

He remembers his friends and him screaming as they fell to their demise, then his back collided with a rock and his whole world became black.

As many of you can probably tell, I'm diverting this from the original movie. I figured since some people have already seen the movie I decided to add in a whole new arc that's not only going to lead you guys wanting more but give the movie more depth and backstory. Anyway, that's it for the first chapter. I hope you all enjoy the new story. And shoutouts to people like Steel Heart Alchemist, PokePikaPower (DeviantArt), and InfernalFox for helping me getting back into writing this amazing crossover. Stay tune for the next chapter!

Now, I need to just find a way to get feeling back into my right cheek after that filling.
