Introducing my inspiration of Lego Dimensions. This big crossover won't only have 14 franchises or only have one team of three, but instead there will be multiple franchises and four teams of three. Who are those teams? Just read this story and find out. Also I do not own any of the franchises in this crossover. They are owned by their respective companies. With that out of the way, let's get started.

At the center of all the Multiverses ever created…

A blue portal opens up and an old man in a robe with a robot come out of it.

"I've found it," the old man said, "I've finally found the center of all the Multiverses. After so many years of searching, it actually exists."

The man walked a couple of steps and then continued speaking.

"I'll be able to accomplish what Lord Vortech failed to do.*"

(*See Lego Dimensions)

"This time," He began, "I won't only conquer the dimensions in one Multiverse, I'll conquer all the dimensions in all the Multiverses!"

The robot cutted in and said, "You do realize that the Tablet of Ultraverse prevents you from doing that right? Not only that, but even if you could do that, you still need the right amount of Foundation Elements to do so. They're the corner stones of time and space. So, they're kind of important to the entire universe."

"I realize that you idiot," The old man said, "But it won't be hard at all because I'll make some friends across the worlds of the Multiverses. I'll have an army and then I'll merge all Multiverses into one so I can control everything."

The robot then said, "Yeah, good luck with that. Now's where my pay like you promised?"

"You're pay?" The old man questioned, "Oh yes. You're pay."

He then opened a blue dimensional portal behind the robot and evilly smirked.

"What?!" The robot said, "That's not what you promised!"

The old man replied, "You fool. I guess even when you're a robot, you still never learn that you can't trust strangers."

The portal sucked the robot in. Causing him to break apart.

"Now that that's out of the way," The old man said, "Where is that Tablet?"

He then walked a couple of miles and saw a light up ahead. It was then he knew of what it was.

"Yes." The man said, "There it is."

He walked over to the light and found the Tablet of the Ultraverse. The stone had scribbles on it that the man paid no attention to.

"With this out of the way," The man said as he approached it, "All of the Multiverses will be mine!"

He then used his staff to smash the tablet into seventeen pieces. Sixteen of them scattered across different dimensions in different Multiverses.

"Hahahahaha!" The man laughed, "It's done! And now to initiate my plan! Sadly, though I won't be able to pass freely between dimensions or Multiverses. However, I can take a note from Lord Vortech.

Using the dimension's law of no-rules, the man then created his own little fortress using the power of his mind.

Soon, in another world….

A blue hedgehog and a two-tailed orange fox flying in a red plane, with the blue hedgehog on the top wing and the fox flying it, are chasing a man and two robots in a flying mobile that is carrying a capsule containing animals.

"Drop the critters, Eggman!" The blue hedgehog said.

The man, known as Eggman, presses a button, releasing the capsule as it drops.

"If you insist." Eggman said, making fun of the blue hedgehog.

"Whoa, that's harsh!" The fox said.

The blue hedgehog does a really fast spin dash off the plane, reaching for the capsule's button but misses. The fox catches him on the plane.

The fox then said, "We'll have to swing back around for it!"

Eggman grinned and said, "Predictable."

The red robot then said, "Very."

Then the yellow robot with a really annoying voice said, "He must really love those things!"

Eggman shoves the robots away and pulls out a laser gun. He aims for where his enemies were but he sees that they're missing."

"Huh?" Eggman said in shock, "Where'd they go?"

"Um sir?" The red robot said.

"What is it Orbot?" Eggman asked in annoyance, "Can't you see I'm busy searching for those furballs so I can shoot them out of the sky?"

The yellow robot then said, "What a pretty blue swirl!"

"Cubot!" Eggman shouted, "I told you to keep your mouth shut until we-"

"Wait," Eggman said, "What blue swirl?"

"I believe," Orbot said, "He's referring to that one."

They then saw a werid blue portal that's pulling the two animals in the plane in.

"What on earth?!" Eggman shouted.

"Sir?" Orbot asked, "Don't you think you should shoot Sonic and Tails down while they're stuck?"

"You're right," Eggman said, "I won't miss this opportunity!"

He then aimed the laser gun at the plane.

"Tails!" Sonic shouted as he hung on to the wing of the plane, "What's going on?!"

"I don't know," Tails replied, "But I can't get the Tornado* to move any faster!"

(*The plane they're flying.)

The blue hedgehog, known as Sonic, then said, "Hang on to that Chaos Emerald you have!"

"Don't worry," The fox known as Tails said, "It's safe!"

Suddenly they got sucked in completely in the portal and then it disappeared.

"Oh I missed!" Eggman shouted in frustration, "I had them right where I wanted them!"

Cubot, the yellow robot, then asked, "Where'd they go? Can we come?"

"Where ever it is they went," Orbot, the red robot, said, "It must be somewhere where they can't be found. Happy day, right boss?"

"Let's not get our hopes up just yet." Eggman answered, "That was a dimensional vortex. And I've detected more."

He then got his mobile running.

"We've got to find one of those vortexes," Eggman said, "There's something weird going on."

Meanwhile in the vortex where Sonic and Tails got sucked into…

They were flying in a weird blue rift which seemed endless.

"What is this strange place?" Sonic asked.

"I don't know!" Tails answered, "But it's making me feel sick!"

Suddenly a yellow device from the Tornado was flying off.

"Oh no!" Tails shouted as he reached for it, "The Miles Electric!"

Sonic grapped it with one of his hands, but it now made it harder to hold on to the wing.

"I got it," Sonic said with a smile in his face, "No worries!"

"Sonic," Tails shouted in worry, "You're slipping!"

"Okay," Sonic replied, "Maybe worry a little."

"Hang on Sonic!" Tails shouted.

"I'm trying," Sonic shouted back, "But it's pulling me!"

Sonic then lost his grip and quickly flew off from Tails and the Tornado.

"Sonic!" Tails shouted as he quickly left Sonic's sight.

"Tails! No!" Sonic shouted.

He then flew down the rift in hopes of finding his buddy.

Suddenly there was a white light growing.

"I don't know where this goes," Sonic said to himself, "But I've got no other choice right now so let's do it to it!"

In another world…

Welcome to the world of Pokémon. This world is inhabited by these creatures called Pokémon. Some people keep Pokémon as pets, but most use them for battles. Right now a tournament is being held in the Unova region. The finals is about to begin. Let's find out how this battle goes.

"Ladies and gentlemen!" The announcer said, "Shortly the final round of the Champions Tournament will begin. So stay seated and get hyped!"

A kid was talking to a player in the tournament that just lost in the semi-finals.

"So the kid* who just beat me," The older boy said, "He's your** friend?"

(*The male protagonist of Pokémon Black 2 and White 2)

(**The Rival in Pokémon Black 2 and White 2)

"You bet he is." The kid said, "He's the new champion of Unova who also saved this region from Team Plasma. Sorry Blue but he's gonna win this."

The older boy, known as Blue, chuckled and said, "You wish, but you don't know Red better than me."

"Red?" The kid asked.

"You know Red right?" Blue asked, "My rival and the most powerful Pokémon trainer in the world."

Blue then gave the kid a cocky look and said, "I hate to say it but you're friend's made it far enough in this tournament. He may have beaten me, but he's in for a surprise."

"Haven't you heard the rumors?" The kid asked.

"Rumors?" Blue asked.

"Rumor has it," The kid began, "That years ago, when Red was on Mt. Silver he was beaten by some kid* from New Bark Town in the Johto region."

(*The male protagonist in Pokémon Gold, Silver and Crystal/Pokémon HeartGold and SoulSilver)

"I've heard of those rumors," Blue answered, "But that's just a rumor. There's a chance that Red continued his winning streak and beated that kid just as easily."

"Even so," The kid said, "You don't know my friend like I do. He's amazing. And is defiantly capable of beating someone like Red."

"We'll see." Blue replied

"Alright!" The announcer shouted, "It's time for the Tournament Finals to begin!"

The crowd went wild.

"In the left corner," He began, "The surprise trainer who's the new champion of the Unova Region!*"

(*You name him whatever you want. Same with his rival.)

The boy then stepped up to the arena.

"And in the other corner," He began again, "The living legend, the unstoppable, the hero of the Kanto region, Red!"

The crowd went really wild to see these two on the arena.

"It's an honor," The boy said, "To battle you today."

Red smiled and replied, "It's always a pleasure to battle a champion."

The two smirked at each other as if they already developed a friendly rivalry.

"You may have beaten Blue," Red said, "But now your real challenge begins!"

"Then," The boy said, "Let's get it on!"

The two then pulled out their Pokeballs and threw it, releasing the Pokémon.

The two Pokémon are released and enter the arena.

"The champion of Unova," the announcer said, "Sends out Lucario!"

"Lucario!" Lucario said.

Pokémon only say their name. Many say they're speaking a language humans can't understand but that's debatable.

"And Red," Announcer continued, "Has sent out Pikachu!"

"You ready Lucario?!" The boy asked.

Lucario looked at his trainer and nodded.

"Let's do it Pikachu!" Red said.

Pikachu nodded.

"Let the battle begin!" The announcer shouted.

"Lucario," The boy shouted, "Force Palm!"

Lucario then charged at Pikachu with his said attack.

"Pikachu," Red shouted, "Iron Tail!"

Pikachu jumped in the air as his tail turned into iron. He then aimed for Lucario.

The two were about to hit when suddenly, a blue portal appeared out of nowhere and a strange blue creature poped out of it. Landing on Lucario, causing both Pokémon to cancel their attacks.

Everybody went silent for what they saw.

"Ow," The blue creature said in pain, "I think I twisted a quill."

The blue spikey creature stood up and looked at his surroundings.

"Hey everybody!" The blue creature said.

Everybody in the stadium gasped as it speaked.

"It appears to be," The announcer began, "To be a talking Pokémon."

A guard came to the arena to get the creature.

"Okay talking Pokémon," the guard said, "No wild Pokémon on the arena. Not even ones that talk. So get out."

"Pokémon?" The blue creature said, "I'm not a Poke-"

He then stopped and thought of something.

"Wait a minute," he said, "Pokémon? Where have I heard that name before?"

"Hey!" Lucario said through telepathy*.

(*Lucario has the ability of human-speaking through telepathy.)

The blue creature looked down and saw that he was standing on Lucario.

"Oh," The creature said, "Sorry."

He quickly got off of Lucario.

After Lucario got up, the blue creature took a good look at him.

"Lucario!" The creature said in excitement, "How have you been? I haven't seen you since we defeated Tabuu.*"

(*Super Smash Bros. Brawl: Subspace Emissary.)

"What?" Lucario said in confusion, "What're you talking about? I've never met a Pokémon like you before."

"What?!" The blue creature said, "I'm not a Pokémon, I'm Sonic. Sonic the Hedgehog. Remember?"

"I'm sorry," Lucario replied, "But that doesn't ring a bell. Maybe it was a different Lucario."

"Whatever," Sonic said as he turned to the people, "Anyway, has anyone in here seen an orange fox riding a red plane come by here?"

The crowd got confused about what he said.

"Hey," Red said, "I hope you don't mind but we're in the middle of a-"

Suddenly another blue portal appeared behind Red and Pikachu.

"What?!" Sonic and Lucario said.

"Oh no," The boy shouted, "Red!"

The blue portal quickly sucked up Red and his Pikachu at the same time.

"Red! Pikachu!" Lucario shouted as he jumped through the portal.

"Hold on," Sonic said, "That's where my friend is."

He then jumped through the portal too.

"Lucario!" The boy said as he was about to jump through the portal but failed because it disappeared before he could make it.

"Red!" Blue shouted.

"What just happened?" The boy's rival asked in confusion.

"Well," The announcer said without knowing what to say, "I don't know what just happened, but it seems Red is missing for the moment. But don't worry we'll have all officers to be on search for him. We will a battle soon. Just hold on."

"Lucario," The boy said quietly, "Where'd you go?"

In the vortex…

"Red! Pikachu!" Lucario shouted as he flew through the vortex, "Where are you?!"

"It's no use pal," Sonic said as he flew right beside Lucario, "Same thing happened to my buddy Tails. Now he's missing too."

"You're friend got sucked up too?" Lucario asked.

"Yeah," Sonic answered, "And nobody gets away with kidnapping my best friend."

Suddenly a white light appeared at the end.

"What's that?" Lucario asked.

"Well a little piece of advice," Sonic said, "Brace yourself!"

They then fell through the light.

In another world…

A group of six people were together on top of a huge white castle in a strange world. Three of them were humans, two boys and one girl, and the others were a mouse, duck and dog. The six were getting ready for a big battle.

"Xemnas," One of the boys shouted, "You can't hide from us!"

The mouse turned and stated, "We're not gonna let him get away now!"

The girl saw something and said, "Look at that!"

A giant door floating in the air then suddenly appeared out of nowhere.

The dog then asked, "What's goin' on?"

The mouse answered, "Kingdom Hearts."

"Let's go." The other boy said, "Xemnas must be inside."

The mouse then said, "The worlds gave us this doorway."

"They want us to be the guardians of their destiny." The mouse continued.

The first boy nodded and the other boy said, "Once we go through, there's no turning back."

"It's victory," the other boy said, "Or oblivion."

So, Sora," The other boy said to the first boy, "Are you ready?"

The boy, known as Sora, looked at the other boy and said, "Whenever you are Riku."

"Your majesty?" The other boy, known as Riku, asked.

"Please Riku," The king said with a smiled, "Call me Mickey. And I'm always ready."

The mouse, known as King Mickey, turned to the other and said, "Donald, Goofy, protect Kairi. Okay?"

The duck and dog, known as Donald and Goofy respectively, saluted and said, "Yes sir!"

"Summon your Keybaldes." Mickey said.

Sora and Riku did as he said and Mickey did the same. Sora and Mickey's Keyblade were the same design but with different colors. Riku's was in a darker style.

The three face the door and set up their Keybalde to open the door.

"Sora!" The girl, known as Kairi, shouted, "Help!"

The three turned around and saw that a portal that appeared behind her was pulling her in.

"Kairi!" Sora shouted as he ran over quickly.

Donald and Goofy did their best to help her, but by the time Sora got there she got sucked in and then the portal disappeared.

"What the?" Goofy said, "Where did Kairi go?"

Suddenly another blue portal appeared and it dropped off a two blue creatures. One was a spikey blue creature while the other was a jackal-looking creature.

"Ow." The spikey creature said in pain, "I may need to check my quills when I get back."

The jackal-looking creature had an annoyed look on his face as the spikey creature landed on him.

"Is this gonna be a normal thing for you?!" The creature asked in annoyance and was using telepathy to do human-speech.

"Oh," The spikey creature got and said, "Sorry Lucario. Guess I'm so fast I can't see where I'll land."

The spikey creature chuckled and the other creature, known as Lucario, replied, "This is no time for jokes Sonic! We need to find out what's going on!"

"You!" Sora said in anger, "What did you two do to Kairi?!"

"Kai-who?" the spikey creature, known as Sonic, asked, "Never heard of her."

"Quit the act!" Sora shouted, "I know you two did something!"

"Relax Sora." Riku said as he stopped Sora from attacking.

"I don't know who you're talking about," Lucario said, "But did any of you see a boy dressed in red with a yellow mouse come by here?"

Mickey giggled and said, "Nope just me."

Riku then explained, "All we saw was our friend Kairi get sucked into a weird vortex."

"I've handled stuff like this before*," Sonic stated, "I think it was some kind of dimensional rift. Where'd it go?"

(*Sonic's referencing the Warp Rings that lead to the Special Zone and the events of Sonic Rush and Sonic Rush Adventure.)

"It disappeared after it took her." Mickey answered.

"So you didn't cause that?" Riku asked.

"Nope," Sonic answered, "We're just as lost as you guys. And I hate being lost."

"Sorry about that." Sora said, "It's just I've been waiting to see her again for a long time.* Seeing her disappear again is just…"

(*Sora's been searching for her in Kingdom Hearts II.)

"Don't worry Sora," Donald said, "We'll find her again."

"You mean I have to go on another journey to find her AGAIN?!" Sora asked as he got tired of the thought.

He then stood up straight and said in a happy voice, "Well, adventuring got me this far."

"We'll start searching for her as soon as we defeat Xemnas," Mickey said, "Come on Sora."

"Right." Sora replied as he started walking.

But as soon as he got to Sonic and Lucario, another blue vortex appeared below their feet. Then they quickly got sucked in and the vortex disappeared.

"Let's go Sora!" Riku said in a confidant voice.

After a second Mickey said, "Sora, come on let's go."

"Your majesty," Donald said, "Their gone!"

Riku and Mickey turned around and saw that Donald was right.

"What?!" Mickey said in confusion, "Where'd they go?!"

"They must've got sucked up by another vortex." Riku guessed, "What should we do Mickey?"

Mickey thought for a second and then explained, "Well Xemnas can't do anything out here while he's in there. So why don't we go find a vortex so we can find Sora."

"And then go in and defeat Xemnas," Goofy said, "Right?"

"Right Goofy," Mickey said, "Now let's go search."

Then they went downstairs to look for a vortex.

In the vortex…

"Woah!" Sora shouted as they flew in the vortex, "This is crazy!"

"We've bounced from world to world so far," Lucario said, "I don't trust we're this will lead."

"I've got one idea." Sonic said not really confidant with his idea.

He got out his Miles Electric and began typing on it.

"What're you doing?" Lucario asked.

"Well if my buddy Tails were here," Sonic said, "He might find what's causing all the rifts, find the point of origin and disrupt it. But since he isn't here I'm just gonna press random buttons in hopes it might do something."

"What?!" Lucario shouted, "Don't do that! You don't know what you're doing!"

"You got a better idea?!" Sora asked.

Suddenly the Miles Electric beeped.

"Wait," Sonic said, "Something happened.

Suddenly another pathway was created and they started flying down that path.

"Okay," Sonic said, "Stuff's happening now."

"Let's hope," Sora said, "That there's a soft landing at the other end of this."

Then the light on the other end grew brighter.

?...

The three popped out of the vortex. Landing on some weird gateway in a space-like world.

Suddenly the gateway was shaking a little bit.

"Look out!" Sora shouted.

The three then quickly jumped out of the way before the gateway exploded.

When it did, five purple items got sucked into the vortex the three came from. The vortex then disappeared.

Sonic got up and said, "Well I don't know exactly what I did, but we're still alive so I must've done it right."

Sora then got up and replied, "Good job. I almost thought we were done for."

Lucario got up and said annoyed, "Next time, let me figure out how to get out of there."

Lucario then looked at the pad where the gateway was.

"I think the first thing we should do right now is fix that gateway." Lucario said.

"The pieces are everywhere," Sora said, "It'll take hours to-"

Suddenly Sonic ran really fast that he became a blur. In no time at all the gateway was fixed.

"Woah!" Sora said amazed, "Awesome! How'd you do that?!"

Sonic explained in a cocky voice, "Oh well you know I'm a gifted hedgehog who always sends an evil scientist packing and is the best looking hedgehog on the planet. No big deal."

Lucario then asked, "Did any of you notice something fly into the vortex we came from."

"Yeah," Sora answered, "They looked kind of important."

Sonic then said, "Well if they're so important, let's go get them."

"Let's?" Lucario asked.

"Aren't you guys coming with me?" Sonic asked, "I mean I gotta save Tails."

"And I need to save Kairi." Sora said.

"Red and Pikachu need saving too," Lucario said, "So I guess since we each of someone to save, it would be appropriate for us to team up. Right?"

"Heck yeah!" Sonic said.

"It's more fun that way anyway," Sora said, "Believe me I know."

Lucario was silent for a second. Then he smiled and said, "You're right. Okay I'll go with you guys."

"Sweet." Sonic said, "I'm Sonic. Sonic the Hedgehog!"

Sonic then put his right hand in the middle of them.

"I'm Lucario!" Lucario said as he put his hand on top of Sonic's.

"And I'm Sora!" Sora said as he put his hand on top of Lucario's, but was careful of the spike.

"Okay," Sonic said, "Let's get going!"

"Yeah!" Lucario and Sora said.

Then the vortex opened in the gateway and the three jumped through it.

And so the first team of the adventure has been formed. What world will they enter first? Who else will get involved? Find out soon.

Sonic the Hedgehog is owned by Sega. Pokémon is owned by Nintendo. And Kingdom Hearts is owned by Disney.
