This is the actual start of my big crossover story series that I've been having in my head for quite awhile. I'd explain it, but the story takes care of that. Enjoy.

What is the universe?

That's a definition that has been debated over for ages. The human race has given the universe a meaning, and it is defined as "everything that physically exists, or the entirety of space and time."

Those are what the laws of physics have declared. And those same laws of physics were declared by humans. So in a sense, humans have declared the existence of the universe.

But could there be more out there?

Could there truly be things beyond the universe? This is all in theory, but when you think about it long enough, the facts come together like a cosmic puzzle. There is more than just the universe. In fact, there are probably millions, if not countless universes.

The notion of a parallel universe has always sounded ridiculous to some; a theory only found in science fiction and pseudoscience. But who are we as humans to dictate this? We've created laws of physics, which allow our universe to function. It is interesting to note that we have also created fictional characters that inhabit or media, books and electronic games.

Physics exist in our universe. It is a commonplace phenomenon that we observe everyday.

Then who's to say that somewhere out there; beyond the universe; the imaginative creations of the human race don't exist as well? Perhaps humans are just a creation of other beings. Perhaps we just all are fictional characters in our own right, and we live out the stories being written in some other universe.

In the grand scheme of the cosmos, we may truly never know.

Haruhi couldn't get enough of looking up at the stars. They were a sight that never got boring to her. She always loved the night, because the stars could only be seen then.

Haruhi Suzumiya was like most her age. She was a young, energetic, Japanese high school student, with a particular interest in the bizarre and the strange. To tell the truth, she had no interest in ordinary humans at all.

"I don't have any interest in ordinary people. If anyone here is an alien, time traveler, or esper, please, come see me! That is all."

Those were her first words upon entering high school. After that, she had met a more reasonable male student, whom everyone called Kyon, and with his help, they both started the creation of a school club, which she named "SOS Brigade."

Haruhi smiled to herself at the memories. The stars were shining bright tonight, and she was content sitting on the old swing set in the backyard of her house. It was always the place she would sit and think.

For all her life, she had only wanted the extraordinary, and nothing less. Everything was irrelevant, be it boys, socializing, or even grades. Haruhi Suzumiya's only goal in life was to find the things she always wished for. Something exciting and different.

And she managed to remember the fun she'd had with the SOS Brigade. Her members; Mikuru Asahina, Yuki Nagato, Itsuki Koizumi and Kyon, had become her greatest friends. Not to mention her only friends. On a weekend like this, where she wasn't with her beloved Brigade, she couldn't help but feel lonely. She couldn't help but feel bored.

Being an extremely eccentric girl, Haruhi always wanted something more than what was given to her. She would go impossible lengths to seek it out, and the words "bossy" "persistent" and even "overly optimistic" most certainly described her.

She looked up at the stars again, wishing to herself that something very extraordinary could happen one day. Something she would never forget.

{When will the day come…when something really amazing happens…}, she thought to herself, closing her eyes for a moment. As her vision blackened, she suddenly began feeling wind circling around her; and her chestnut-colored hair was now tossing back and forth against a strong current. It howled in her ears, and she suddenly found herself gripping to the steel chains of her old swing tightly. Fear gripped her for that second, and then her eyes snapped open as the wind came to a calm.

She couldn't believe what she was seeing. Haruhi stood up, rubbing her eyes, and blinking multiple times. She couldn't be seeing right. Something was terribly wrong.

For now, the sky was an orange-yellow color. The stars were gone, and in a matter of seconds, it had suddenly become the light of day. A yellow sun shone in the sky. Haruhi was speechless, turning and running out of her backyard. She was on her way to the house of the person she trusted most. Her friend, lackey and somewhat crush. Kyon.

The sound of a wrench twisting reverberated through the colossal enclosure that Dexter resided in. He was an inventor, innovator and thinker by nature; and most of his spare time consisted of building, creating, analyzing and discovering. He liked things that way.

Dexter was a boy genius, gifted with an astounding mind that could think, calculate and process with the power of a supercomputer. He's measured his own IQ multiple times, and almost every time, it has been between three hundred and four hundred. And it's constantly growing.

"The solitude is nice, computer. I am glad my stupid sister is finally distracted by the seasonal change outside." He stated to his lab's sentient computer. Dexter sighed, letting his hand rest from the consistent twisting he had been doing with it.

"As long as Dee Dee is occupied by the current weather, then I do not estimate any interruptions to your work, Dexter." Computer responded in its metallic, monotone voice. Dexter couldn't help but smile, beginning to twist the wrench on the piece of equipment he'd been working on.

All of a sudden, the light fixtures all through his laboratory began to flicker on and off. Everything began to shake, and Dexter was suddenly looking back and forth, holding onto his piece of equipment for dear life. Then, everything in his lab completely shut down.

"What? Computer! Computer! What is this phenomenon?" he asked his sentient machine, his voice thick with his accent. For a moment, his lab failed to respond at all. Suddenly, the power rerouted to all the lab systems, and computer booted up. It spoke to Dexter in its same, monotone voice.

"Dexter. There has been some sort of temporal interference. I'm running on emergency power. From my calculations, we are no longer on this Earth. I cannot discern where we are exactly, but it is not located in the Milky Way Galaxy."

"Impossible!" Dexter exclaimed, running towards a nearby telescope only forty or so feet away. His black Italian boots squeaked against the floor of his lab, and he pushed in a large green button to activate his telescope. He looked through it, his eyes viewing through blue-tinted glasses and reflective glass alike. When he saw the orange-yellow colored sky, and no sign of clouds, he could only back away in astonishment.

"Einstein's ghost…"

Nigel Uno sat upon his usual seat in the living space of his tree house. He was the leader of Sector V, one of the many sector's of the large anti-adult group; the Kids Next Door. His sunglasses shined as he sat in his large centered seat in the middle of Sector V's living room. He was frowning.

The other members of his team were enjoying themselves while their leader was more content on pondering. Numbuh 2 and Numbuh 4 were busy attempting to beat one another in the video game world, each boy furiously tapping buttons on their joysticks. Numbuh 3 was leaning on the couch right behind them, watching their game intently.

"Give up, Numbuh 4! Can't you see my skills are unmatched?" Numbuh 2 said, taunting his fellow member. This caused Numbuh 4 to only play more furiously. His eyes were largely focusing on the game, with all intent to win.

"I'll show ya skills!" Numbuh 4 barked, tapping his buttons as hard as he possibly could. Numbuh 3 was rooting for him loudly right behind him.

"Come on, Wally!" she said in her usual happy-go-lucky tone. Numbuh 4 was going at it as hard as he possibly could, and Numbuh 2 was making it look like he wasn't even trying.

Finally, a large "YOU LOSE" came up on Numbuh 4's side of the screen. He got up; an infuriated look on his face.

"Check…and mate." Numbuh 2 said, smiling as he put down his controller. Numbuh 4 looked about ready to rip his hair out. As he was about ready to explode, Numbuh 3 grabbed him from behind, hugging him tightly. Numbuh 4 could only blush as he was held in the girl's green-sweater grip.

"You look worried." Numbuh 5 said to her leader, who was broken out of his train of thought. He turned to her, letting a small smile creep on his face.

"I'm fine. Just have a lot on my mind."

Numbuh 5 looked at him like he was lying. She tipped her bright red hat.

"Whatever you say, Numbuh 1."

As Numbuh 1 thought, he let his mind go through recent happenings. There were so many adults to handle on this planet. And most of them wanted nothing more than to make the lives of children miserable. And it was the Kids Next Door's job to stop that.

It was his job.

As he thought, the tree house began to suddenly rumble. It shook and shuddered, prompting each of the kids to hang onto whatever they could. For a few seconds, it felt like the tree house had become a top, spinning like crazy. Then, it stopped.

Numbuh 1 got up, disheveled and dazed. He rubbed the back of his head, fixing his sunglasses as he looked out the window. There were no more clouds. The sky outside had suddenly gone from blue, to an orange-yellow. Numbuh 4 was the first to speak.

"Hey! I didn't know the sky was orange!"

Sonic loved running. It was his life, his livelihood, his past, present and future. There was nothing more in the world he loved to do. He grinned as he sped fast along his usual running spot.

Emerald Coast was a long stretch of land that was mostly beach, but its beauty never ceased to amaze anyone. It sat right by Station Square, a large coastal city that was always bustling with life.

As the blue hedgehog ran, his thoughts shifted around various subjects. His friends were all around these parts, and he kept them close. Knuckles, Tails, Shadow and even Amy were among some of his closest confidents. And Sonic could say that even though Amy Rose was still a pest at times. Others, like Silver, Blaze and Team Chaotix; were allies he frequently associated with.

Of course, Sonic had his enemies. One such was Dr. Eggman; a megalomaniac genius who would stop at nothing to conquer the world. Sonic stopped his various attempts every single time. So far, at least.

And now Sonic was doing what he loved most. Running. Of course, he had a destination in mind. And that was the workshop of his best friend, Miles Prower, or simply; Tails.

"Hey Tails!" Sonic said, skidding to a stop as he finally reached the inside of the fox's workshop. Tails looked up at Sonic, having been working on upgrades for his Tornado plane, which he'd been building most of his life. Tails offered Sonic a smile.

"Hi Sonic."

Sonic grinned at his friend. The hedgehog was getting used to the slow speed now, and he began to walk more slowly. Before he could walk much farther, the ground began to suddenly shudder and shake, as if being handled by some angry god. Sonic struggled to stay standing, and many of the tools in the workshop clattered onto the floor. After a few minutes, the shaking stopped.

"What was that?" Tails asked, and Sonic shrugged. After doing so, he quickly moved to the door, poking his head outside. Emerald Coast was still where it should be, but now, the sky had become an orange-yellow color, and the sun was in a completely different position in the sky than before. Sonic was speechless.

"Hey Tails….you might want to come see this…"

Jack Skellington sat upon his usual gravestone, staring blankly at the moon. Life had been perfect for him so far. Halloween would come and go, and he and his friends would make it more horrifying every year.

It was great. But Jack always had other things on his mind as well. He and Sally had recently realized feelings for one another, and so, a relationship between them began to develop. Jack wanted to celebrate Christmas from time to time. The seasons came and went as usual.

But staring into the moon, Jack still couldn't help but wish for more. He wanted something that might brighten up his life in ways he couldn't possibly imagine. He had his skull in his bony hands, sighing deeply.

All of sudden, the entire graveyard around him began to shudder violently. Jack was sent tumbling off the gravestone, his skull rolling into the dirt as his body tumbled in another direction. The shaking continued, while his body got up, and began searching around for his head which had tumbled onto the round.

"Over here!" he said to his own body, and it finally managed to find him. It felt good for his skull to reconnect with his neck bone. But when Jack turned to look at the moon, his expression changed to sudden wonder.

It was completely gone. The sky had become a barren orange. The night had suddenly become day.

"What's this…" he said to himself, putting a bony finger on his chin as he observed the sky above.

Brick, Boomer and Butch were brothers. Brothers with a huge rivalry against one another.

"I'm faster!" Boomer said in mid-air, speeding and winding around buildings. Butch and Brick were on his tail, but they just didn't seem to be able to catch up. This only frustrated Butch. He had always been the brasher one.

"Don't waste your time. He'll just get slower as he uses all his speed up." Brick said as he flew beside his brother, knowing very well Butch would attempt to jump the gun. The three brothers lived in the city of Townsville, which was run by an absolutely deluded and clueless mayor. They had once been destructive little boys, and had been even killed for a short period of time. But fate was merciful, and they were brought back to life. After awhile, they began to become more peaceful, having thrown aside their destructive ways.

They made friends with a group of super-powered girls, who called themselves "The Powerpuff Girls". They were crime fighters in Townsville, and they were originally responsible for the brothers destruction. The brothers were colloquially called "The Rowdyruff Boys".

But since having turned over a new leaf; both groups managed to become fast friends in a short period of time. Occasionally, the Rowdyruff Boys would even help take down criminals. Otherwise, they had their fun with their powers. Most of the time, they didn't damage much.

Boomer was still ahead of his brothers, when all of Townsville began to violently shake. All three stopped in mid-air, watching as skyscrapers and all manner of buildings moved back and forth. They looked at each other, as if confused, until the shaking finally stopped. Boomer was the first to notice a change.

"Hey guys! Look! The sky changed color!" he said to his brothers who gave him only one response.

"Cool!"

Jack slashed his blade upward, cleaving much of the dark matter that was Aku into pieces. The great demon roared in pain, slashing downward at the samurai. Jack rolled out of the way of his claw, bringing his blade down again on the shape shifter.

This was it. Their final battle with each another.

They had finally confronted each other, after years of Jack having gone through time and space to search for the demon. He would have killed Aku in his original time, but the demon flung him into the future, right before Samurai Jack would make the final blow. And for years, Jack searched for a way to return to the past, and undo the future that Aku had ruled freely.

And now, after years of searching, he had found his enemy. He drove his blade down again, slicing off another large portion of Aku's form. Jack was fighting with precision; each blade strike causing more damage than the last. He had almost won.

Aku was lying against the dirt, his voice weak as he spoke.

"This is not over, foolish samurai." He said, and Jack stepped forward, his sword raised.

"Your end is now, Aku. You will pay for your evil. You will pay the ultimate price!"

As Jack readied to bring his sword down, the world around him began to suddenly shake and shudder. Wind suddenly pushed against him, causing him to fall over. His vision blurred, and he could see nothing for a few seconds. After a minute, the shaking stopped.

Jack opened his eyes, standing up, sword in hand. He was now surrounded by a city. It was a modern Japanese city, to be more precise. Jack's mind was racing, every thought now focused on where Aku could have gone.

"Aku! AKU! WHAT TRICKS ARE THESE? WHERE HAVE YOU HIDDEN YOURSELF?!?!" he roared, slashing his sword downward in anger. Samurai Jack was now in a strange new place, and once again, Aku had eluded his judgment.

Kyon heard the rumbling all around him. It had woken him up from his deep sleep. He woke up and tumbled out of his bed, and if felt like an earthquake was going on.

{What…}, he thought, groggily getting up and walking slowly out of his room. He stepped into the hallway, noticing all the lights were off. Through the window, he could see that sunlight was poking through.

{That can't be right…}, he said, wondering how it could be morning. Kyon swore he only went to sleep an hour ago. The Japanese teenager walked slowly towards his front door, opening it, and letting his jaw drop from the sheer surprise. He couldn't believe what he was seeing.

The sky was orange. It was a golden-yellow orange. There were absolutely no clouds at all.

Kyon looked from side to side, peering down either end of his street. He could see no one in sight. He heard no sounds. Before he could look any further, he heard a recognizable voice all speak.

{This is strange, isn't it?}, someone said, and Kyon turned to see that a friend of his, Itsuki Koizumi, was walking up the street.

{He sure got here fast….and why is talking so calmly? The sky is orange for God sakes!?!} Kyon thought to himself, walking towards Koizumi to greet him.

Itsuki was a member of a school club that Kyon had joined some time ago. It was called the SOS Brigade, and it was created by a very eccentric girl by the name of Haruhi Suzumiya. She proclaimed the club's goal to "Seek out time travelers, aliens and espers, and to have fun with them!" Kyon always sighed to himself when he heard that.

Itsuki himself was an esper, which meant he had paranormal abilities. Apparently, he could become a red-like energy form when he was in an area called "closed space".

In truth, Haruhi Suzumiya actually had the power of a god, although she herself didn't know it. When she got into a bad mood, huge, dimensional areas called "closed space" would appear, and it was the job of the espers to close each one. They would enter them, and then destroy large giants that roamed inside them. After they did that, the area of closed space would dissipate. But Haruhi could indirectly change reality itself based on her emotions. Kyon had found it out only a short time after meeting her.

Kyon had been a normal student until he met Haruhi Suzumiya. Then his life became anything but normal. Haruhi bossed him around like there was no tomorrow, and by complete chance, he found out that Itsuki was an esper. Yuki Nagato, another member of the club, was a silent, bookish girl who was actually an alien. And there was Mikuru Asahina, who was a sweet, beautiful girl who was actually a time traveler. They had all revealed their identities to Kyon, and each of their goals was simple.

Keep Haruhi Suzumiya content. Or the universe would suffer. Because as she got more mad, reality itself would distort until it got to a breaking point.

{I think that breaking point has been reached this time…} Kyon thought as he finally approached Itsuki. Kyon distinctly noticed how he had not heard a single sound or seen anyone else besides Itsuki this whole time.

{So Itsuki….you wouldn't happen to know why the sky is orange, would you?} Kyon said sarcastically, and Itsuki had his hands in his pockets, calm in his tone of voice.

{I've thought of some possible reasons why. But there's truly only one real reason.} He responded, taking his hands out of his pockets. Kyon knew exactly why they were here. He put a hand on his forehead.

{Haruhi. It's because of her, isn't it?} Kyon asked, suddenly feeling stressed.

{Most likely. Though I'm curious about what exactly she was thinking. It seems we're not even on Earth anymore. In fact, I can't contact my colleagues at all. It's quite intriguing actually.} Itsuki responded, almost smiling.

{Intriguing?!? We're on another planet and you're intrigued?!?} Kyon thought to himself, getting slightly angry at Itsuki's calmness. He sighed.

Haruhi had really done it this time.

Some notes:

If you like this, or don't like it, please review. Reviews are what keep me going. Also, if you didn't guess any words inside { } mean that those words are being spoken in Japanese. Know that for future reference.

Oh, and for those reading my solo fanfic, The Attraction Of Haruhi Suzumiya, you'll notice that their will be a "connecting point" between that story and this one. It hasn't been revealed yet, and I won't do so, but it wll make sense when it is.
