A/N: The 10th Anniversary was yesterday so here's the 10th Anniversary Special, which is a cross over with two of my other fics. Which two? Well if you having figured it out by the preview from yesterday's Biju Biju Fruit Chapter they're Ponies One Half, my second most popular story and Titania Falls which is my 3rd most reviewed story (Though when I came up with the plot of this story it was the most reviewed story that had nothing to with One Piece of Naruto... which is quite a fete fi you think about it). It helps that they have similar plots: Someone ends up stranded in another world... though the actual plots of the stranding are very different... If you haven't read one or both stories don't worry... There's a lot of exposition about the characters in this chapter... if you have read both stories... I apologize for the massive amount of exposition... Anyways enjoy the story! And once Happy 10th Anniversary Biju Biju Fruit!

Disclaimer: We've been through this for over 10 years! I don't own One Piece, Ranma or Naruto, I've been through there for almost five years! I don't own My Little Pony Friendship is Magic! I've been through for 2 years I don't own Fairy Tail and I've been over this for a little more than a year... I don't Own Gravity Falls! Got it?

Luffy: Did you have to put it that way?

Emma: Hey it's celebrating 10 years of a story! I had to do something special!

The Biju Biju Fruit: Crossed Paths

Chapter 1: Whirlpool To Adventure

It was just a normal day on the Thousand Sunny. The sun was shinning and ocean was gentle. Just a nice normal day…

"So bored!" yelled Luffy.

"I know!" muttered Naruto, "Just want something to happen."

"Bored, bored, bored." Said Luffy.

"Then do something!" yelled Kiba.

"You want to start a fight?" asked Naruto.

"What? No…" said Kiba with a sweat drop while Akamaru just sighed.

At the garden, all of the crew's girls decided to just hang out together for girl time.

"Will you shut up!" yelled Nami who was sun bathing.

"It's a nice quiet day where nothing is happening! WE should enjoy it for once." Said Ino.

"Here, here!" agreed Sakura.

"So Hinata… what's exactly going on with you and Naruto?" Fu with a sly smirk.

Hinata blushed.

"Look you better not be thinking what I think you're thinking!" said Ino.

"What no… I didn't mean it that way." Said Fu.

She looked at Robin and Isaribi who both shrugged not wanting to get involved with that.

Sanji came up with plenty of drinks for the girls.

"Here you go ladies!" said Sanji.

"Why thank you Sanji." Said Nami.

Sanji immediately exploded in hearts.

"Are you going to do that all day?" asked Ino.

Sanji stopped and looked at Ino.

"I'm surprised Brook hasn't bothered you." Said Sanji.

"Already handled him." said Sakura with a shrug.

Elsewhere on the ship Brook was upside down.

"Hey Brook you okay?" asked Chopper.

"I'm bruised and beaten but I have no skin to bruise!" said Brook.

"Bones can bruise too." Pointed out Chopper.

Meanwhile Zoro and Sasuke were sparing.

As they were there was an explosion from down below. Both of them noticed Usopp and Franky running out of the workshop.

"Is everything all right?" asked Sasuke.

"Just some we're working on…" said Usopp.

"Uh-huh." Said Sasuke.

In the Crow's nest Gaara was keeping watch when he saw something wrong with the ocean.

He got a bad feeling.

Back with Naruto he got a bad feeling.

"What's that." Thought Naruto.

"I don't know… it it doesn't feel right." Said Kyubi.

With the girls Fu got the feeling too.

"You feel that?" asked Chomei.

"I do…" thought Fu.

"Something's bad going to happen." Said Chomei.

"Hey!" called out Gaara, "A whirlpool is forming!"

"What!" yelled everyone on the ship.

They all went to where the wheel was and saw the whirlpool forming.

"Franky!" said Luffy.

Franky tried to switch to the wheel, but something was preventing him.

"That's no ordinary whirlpool." Said Kyubi, "It's something else…"

"How do you know?" asked Naruto.

"Everyone brace yourselves!" yelled Zoro.

The ship fell into the whirl as it began to fall in.

Naruto grabbed Hinata.

The two looked at each other.

However before either of them could say anything Luffy grabbed the entire crew into a giant group hug.

However once they were in the center of the vortex something strange happened, Instead of falling under water they were in a strange vertical tunnel of blue light.

"What the!" yelled Sanji.

Luffy let everyone go, as they all looked around.

"What is this?" asked Kiba.

"I have no idea." Said Robin.

Little did they know was that they were in a tunnel between worlds.

For there were many worlds… many, many… worlds where Naruto and Luffy never knew each other or even existed at the time. Worlds where Luffy was Naruto's reincarnation, worlds where Luffy befriended Naruto during some sort of exam, worlds where Naruto was sent there from another world… even worlds where they were members of a team of gender bending super heroes…

However they were not heading to any of those worlds.

Soon they were out of the tunnel having appeared in a rather strangely colored sky and about the land on a strangely assembled group of people.

However it is probably best to go back a few hours…

In a different world, in a strange room a man in late 50's slept on a console, he snored when finally some beeping from the machinery woke him up. He put on his glasses and looked around the room.

This man was Stan Pines, to the public he was a two-bit conman who ran a tourist trap called the Mystery Shack.

But in his basement had a secret, a secret that only one other person knew about.

He looked around and noticed the print out, he looked at the printout, normally the print out had percentage numbers on it, however now it just read "Error" over and over again.

He looked through a window and saw a strange triangle shaped object was glowing, that part was normal.

But in the center of it, the light it was emanating seemed frozen.

"You have got to me kidding me." He muttered.

He wasn't sure what to do… other than go get the only other person who knew about it.

He headed to the elevator to upstairs. He then went up some stairs to his gift shop (He did run a tourist trap after all) and then headed upstairs more from there. He knocked on the door.

It opened and a woman in her mid 30s with long red hair opened the door, she was Erza Pines, Stan's ex-niece in-law.

Why would his ex-niece in law be living with him. Well the truth was she was a wizard from another world, and he was the first person to find her. She met his nephew something happened and they got married.

After the divorce she went to live with him along with her two children, it was a temporary situation until she could find her own place…

It's best not to get into why she was having a hard time.

"Stan do you have any idea what time it is?" asked Erza.

"There's something wrong." Said Stan.

Erza immediately knew what her was referring to.

He took her to the basement and she looked at the strange device.

"What happened?" asked Erza.

"I don't know." Answered Stan.

"Did you fall asleep?" asked Erza.

Stan didn't answer causing Erza to sigh.

"Look it doesn't matter we have to fix this." Said Stan.

"How?" asked Erza.

Stan sighed.

"30 years…" muttered Stan.

"I know." Sighed Erza.

Stan then punched one of the machine.

"Punching it isn't going to help." Said Erza.

"I know." Muttered Stan.

"Maybe leaving it alone for a couple days might fix it." Sighed Erza.

"Maybe…" sighed Stan, "This is going to be a pain."

"You waited 30 years, this is nothing compared to that." Said Erza.

"The day hasn't even started yet and it's already bad." Muttered Stan, "I wonder if it's can get any worse."

"That reminds me." Sighed Erza deciding to lighten the mood, "Invited my team for breakfast."

Erza was not the only wizard in that world. About a month before more wizards showed up, and they knew Erza, in fact they were belonged to the same wizard guild as her.

Not only that but before she ended up in that world she was part of a team and her team were among those that showed up.

Though it turned out that original world moved much slower than the world they were currently in so it turned out while she lived in that world for 15 years, to them it was only four months.

Stan groaned.

"Why?" he asked.

"We have a job in the morning and it's closer to the Shack than the Guild Hall." Said Erza.

"If there's any damage their paying for it." Said Stan.

"I was expecting it." Laughed Erza.

Both of them decided to leave for the night, but Erza did look at the strange machine, getting a sense of unease.

Hours later in a completely different world. In a room with many doors, and a table in the center two ponies examined a container that had a green flame in it.

One of the pony was a lavender unicorn with dark blue mane and tail that had a pink and purple streak and a mark on her hind that was a star surrounded by other stars.

She was known at Twilight Sparkle.

That other was a dark blue alicorn with a main and tail in the shape of an ethereal star felid. She too had a mark on her flank, this time it was a crescent moon on a black field of some kind. She also wore something that could be described as royal vestments.

And she was Princess Luna.

As both of them examined the container, a human and another pony entered the room.

The human was a teenaged boy with hair put into a pigtail and wore Chinese clothing. His name was Ranma Saotome.

The pony was a sky blue Pegasus with rainbow mane and tail. On her flank was a cloud with a rainbow lighting bolt coming from it.

"Hey Twi, Luna what's wrong?" asked Ranma.

"The flame is frozen somehow." Said Twilight.

"Without it we can not get in contact with any pony from Equestria." Said Princess Luna.

"What, you're kidding." Said Rainbow Dash.

The truth was that Twilight, Rainbow Dash and Princess Luna and other Ponies weren't native to this world. Twilight, Rainbow Dash and four others used a spell that accidently transported them to this world. Princess Luna and three others followed them. And since then they've been stranded, but the did have a way to not be seen.

Also that fire was a magical way to communicate with their home, world. The only way in fact.

"We woke up with it like that." Said Twilight.

"I fear something is very wrong." Said Princess Luna,.

"Everyone! Breakfast is ready!" called out a kindly voice through out the house.

"Be right down Kasumi!" called out Rainbow Dash.

"Come on, eat breakfast first then worry about the fire later." Said Ranma.

"He has a point." Said Princess Luna.

"Fine." Sighed Twilight.

They all went down stairs for breakfast where everyone who lived there was crowded around a table.

This house was officially known as the Tendo Dojo.

As it was dojo run by Soun Tendo. A middle-aged man with long hair and mustache.

Soun had three daughters.

Oldest Kasumi who was 19 and had her long brown hair put into a ponytail.

The middle daughter Nabiki who was 17, who had her hair put into a Paige boy cut.

And his youngest Akane who dark blue hair was barley past her shoulders.

Ranma and Akane were engaged to married, but then thing were a little complicated.

See in China Ranma defeated Shampoo (a girl with long blue hair put into a strange style), an amazon who's laws states that if a male should defeat her they would get married.

There was also another law. Stating if the man has more than a fiancé then he can marry them both.

Then there was Ukyo, a teenaged girl and Ranma's childhood friend, she also there and she too was engaged.

The three got along family well, and the two lived there along with Cologne Shampoo's great, great grandmother, who was a very tiny old woman.

Also Ranma's father Genma was there… how was currently a panda…

Don't worry… there's a reason why he was panda at the moment.

However there were also the ponies.

One of them was an orange one with no wings or horn, they were called Earth Ponies, and this one also had a yellow mane and tail that were tied at the bottom, her mark was three red apples and also wore a Stetson, she was Applejack.

Then there was a yellow Pegasus with a long pink mane and tail, with three butterflies as her mark, she was Fluttershy.

Then there was a white unicorn with a curly purple mane and tail, with three diamonds on her flank, she was Rarity.

Then there was a pink earth pony with a very poofy magenta mane and tail with three balloons as her mark, she was Pinkie Pie.

Then there was young earth pony, that was yellow, with a red mane and tail, she didn't have a mark (as young ponies didn't) with a pink ribbon, she was Apple Bloom and Applejack's little sister.

Then there was young white unicorn with a pink and lavender mane, she was Sweetie Belle and she was Rarity's little sister.

Next was a young orange Pegasus with a purple mane and tail and she was Scootaloo.

And finally was a very young alicorn foal that was a very light pink and a rainbow mane and tail, she was Prism Star… and well she was a combined clone of Twilight, Rainbow Dash, Applejack, Rarity, Fluttershy and Pinkie Pie…

It's a long story but her name was Prism Star.

"You like that don't you?" Kasumi asked the baby who only cooed in response.

That was when a somewhat beaten up teenaged boy wandered in. He had a very large backpack and had a yellow and black bandana on his head.

"I'm back!" he said.

He was Ryoga and he sort of lived there. He had no sense of direction (even worse than Zoro's).

"Oh Ryoga!" said Fluttershy flying towards him, "What happened?"

"It's a long story." Said Ryoga.

Back in the other world, Erza making breakfast while Stan read the paper.

That was when two 12 olds entered the kitchen. One was a girl and the other was a boy, they were Erza's twin children, Mabel (the girl) and Natsu (though everyone called him Dipper) both of them had curly brown hair (Mabel having it long and Dipper having it short) and also Mabel had braces.

"Morning mom!" cheered Mabel.

"What are we expecting guests over for breakfast."" Asked Dipper noticing how many pancakes Erza was cooking.

"We are." Said Erza taking some fish out of the oven.

"Oh I wonder who it could be." Said Mabel just as Erza poured some alcohol over some of the pancakes and set them on fire.

"Seriously?" asked Dipper who could figure out due to the food preparation.

"Good morning!" said a young man with pink hair wearing a vest, white scarf that was patterned like dragon scales white puffy pants, he was Natsu Dragneel, a type of fire wizard, and one of the skills he had was eating fire which was why Erza lit the pancakes on fire.

"Hey guys." Said a teen girl with shoulder length blonde hair with some pulled into a side ponytail entered alongside with him. She was Lucy Heartfilia, a celestial wizard (which in turn is a type of summoning wizard).

"How's it going." Said a young man with spikey black hair, wearing nothing but his boxer shorts and not noticing that he did. He was Gray Fullbuster, an ice wizard who had a really bad habit of stripping with out noticing.

"Hey guys!" said Mabel.

"Gray, your clothes." Said Dipper.

"Oh come on!" yelled Gray.

"How did you get in here?" asked Stan.

"You left a window open." Said a talking blue cat with wings flying past him, he was Happy… Natsu hatched him from an egg as a child.

Yes… a talking blue cat that was hatched from an egg…

"So you broke into my house and let them in?" asked Stan.

"Says the guy who impersonated a dentist." Said Natsu.

"And invented his own crime." Added Lucy.

"And once dragged us into a counterfeiting scheme." Added Dipper.

"Not to mention that time you committed llamacide." Added Erza.

"You won't let it go, will you?" asked Stan.

"It was a llama!" said Erza, "It didn't know anything…"

Lucy, Gray, Natsu and Happy looked at the twins who shrugged, they didn't know what story either.

And so they began to eat breakfast.

As they did Dipper noticed some wrong with his great uncle.

"What's got you in a bad mood?" asked Dipper.

"Nothing." Muttered Stan.

"Your uncle's just having a bad day." Said Erza trying to brush it off.

"So why are you having breakfast today?" asked Mabel changing the subject.

"Giant monster job." Said Natsu.

As they told them about the job that day Erza looked at Stan, knowing he was worried about the device in the basement.

In the other world Ryoga finished his story.

"Geez I wonder how many people just took your picture than help?" asked Rainbow Dash.

"Too many." Sighed Ryoga.

Due to Ryoga's lack of direction he was internet celebrity.

"Oh you're here now, so it's okay." Fluttershy making Ryoga blush a little.

"I'm done." Said Twilight.

"Seriously?" asked Rainbow Dash.

"I have to figure out what's wrong with the flame." Said Twilight.

"Wait the flame?" asked Akane.

"That thing you use to send letters to Equestria?" asked Ukyo.

"It is comply frozen for some reason." Said Princess Luna, "But I am not done with breakfast. Wait until I am done."

Twilight sighed.

"Fine…" she sighed.

At the very same moment in both worlds an earthquake stuck.

In both places they all braced for it. Ducking and covering or using magic to protect from any sort of debris.

In the Tendo Dojo, once it was over everyone breathed a sigh of relief.

"Well that could have been worse." said Applejack.

"Uh… guys…" said Scootaloo who was sitting by the doors to the garden.

They all looked up at the sky and it was strange, instead of blue it was a swirling mass of colors like a soap bubble.

"Okay… that's definitely not normal." Said Ranma.

Pinkie pulled out clothes from somewhere and tossed them at the other ponies.

None of them argued as they all put on the clothes, then they all grabbed some glasses of water and splashed themselves, turning into human girls.

The thing was that they were also cursed, when they first landed in that world they landed in a place called Jusenkyo, a place with many springs and if you land in one you will turn into whatever drowned there last, but only when splashed with cold water, hot water turns them back but it's only temporary.

They weren't the only ones with the curse, Ranma also turned into a girl, Ryoga turned into a pig and Genma turned into a panda (which he obviously why he was a panda).

However the pony turned girls also had alias in human form, Twilight was Hikaru Hakumei, Rainbow Dash was Ran Issanni, Pinkie Pie was Momo Mochi, Fluttershy was Chiyo Onbin, Rarity was Belle Perle, Applejack was Alex Jackson, Sweetie Belle was Suzette Perle, Apple Bloom was Blossom Jackson, Scootaloo was Haruka Gentsuki, Princess Luna was Diana Tsukino and Prism Star was Hoshi Tsukino.

It should also be noted that Diana's hair wasn't ethereal but was a light blue color and shoulder length.

Once they were all dressed and they left the building to get a gauge on what was going on.

In the Mystery Shack. They all got out from the under the table.

"Could this day possibly get any worse?" asked Stan.

Gray noticed the say from the window.

"What's wrong with the sky." Said Gray.

They all left the Mystery Shack to see what happened.

When both group left their houses they noticed something strange… namely those two houses were just yards apart now.

"What the…" muttered Stan.

"What's going on?" asked Soun.

Both groups looked around, what could have been either a nice neighborhood or a forest was now a mixture of the two.

They noticed that were many houses dotting the area like a mismatched neighborhood.

But before any of them could ask any questions to the other group, there was a bright flash of light and the Thousand Sunny appeared in the sky. Of course it started falling.

They all stared at the pirate ship that appeared in the sky.

Thankfully before it could crush any of them, suddenly Diana's hair once again turned ethereal, her hands glow a dark blue and the ship and its occupants were now floating.

On the ship they didn't know how to react.

"Well… this is interesting." Said Luffy.

On the ground those from the Mystery Shack stared at Dianna. However Erza looked at Diana's hair and noticed the hair of her companions.

"It can't be…" thought Erza.

Momo on the other hand looked up at the Thousand Sunny then at the wizards then back at the Thousand Sunny then back at the wizards.

"No way!" she thought.

Elsewhere a strange place a strange mismatched creature appeared.

He was known as Discord.

He sighed.

"Great… just one of my worlds had to be a target for that thing…" muttered Discord.

She snapped his claw and created a chair.

"Great… I'll be back in Equestria unless they figure how to beat it." Sighed Discord.

"Well, well, well… you created quite the digs." Said a voice.

Discord turned around and saw a yellow one-eye triangle with little arms and legs, wearing a top hat, bow tie, he also a brick like pattern on his body.

This Triangle was known as Bill Cipher, little was known about him, but was often referred to as a "dream demon".

Discord smirked, "So Bill Cipher." He said with a smirk.

"Oh you know who I am, I should have known with the Equestria sprit of chaos and disharmony would know me." Bill said with flattery filling his voice.

"So I take it that world you're trying not take over is the other one?" asked Discord.

"Yes." Said Bill then turned red, "WHY THAT… I HAD CLAIM ON THAT WORLD!"

"You know that is doesn't care about claims." Said Discord.

Bill turned back yellow.

"You have a point." Said Bill.

There was a small silence.

"You want to hang out?" asked Discord.

"Sure why not!" said Bill.

While the two being of destruction, chaos and other evil things knew what was going on the Straw Hats sure didn't and little did they know that they were getting dragged into something that they would never expected.

Next Time: The groups of people must figure out what's going on. When Fu discovers everything might be covered by a dome they explore the edge, but when something attacks them what will happen? Find out next time!

A/N: Okay just clearing it up now, this story is 100 percent non-canon on all fronts. Also the story points:

The Biju Biju Fruit: Before Shiki... though no references to Zoro's injuries (much like the canon version of Strong World)

Ponies One Half: In between Chapter 119 and 120 (There will be references to the giant robot that the Cutie Mark Crusaders built).

Titania Falls: In-between chapter 47 and 48 (Soos has magic but Robbie's still moping about Wendy... and yes that's a plot point).

So yeah... that's where the story takes place.

Also there's three acts to the story, the first act is them figuring out what's going on, the second act is character interaction and the final stopping the thing causing it. I'll try to keep most of the character interaction focused on The Biju Biju Fruit cast since this is technically their story but expect some character interaction between the other two stories... mostly in the form of Bill and Discord... because it's Bill and Discord... Also a few other things...
