(A/N) Hi. And, uh, welcome to Code Lyoko: World Swap. In this story, we venture into the mysteries of relation, separation, and……. And……. I sound like a teacher, don't I. Sorry, I'm new to this. For this is the first time I have written solo. My first fic was authored by both my big sister (Luthien Eowyn) and I. That first fic was Behind the Cards, but since I'm experiencing writer's block for that story, I figured I'd write this story while the block in my mind thaws. Anyway, enough about me, and onto the story. Ladies and Gents, I present to you Code Lyoko: World Swap. (Dramatic background music. You fill in the blanks, ok?) And also, Code Lyoko does not belong to me. But a good amount of the plot does!

Chapter 1: Jeremy's Quest

"Jeremy?" A virtual voice called. "Jeremy?" This time shouting. "Huh, what?!" Jeremy woke with a start. He had dozed off in front of the screen. His friends were in trouble.

"What's up Aelita?" he said. Aelita was the virtual character that had been made when Lyoko had been. She was dressed oddly and had pink hair. Aelita was the reason they were even there. Otherwise, they would have long since shut off Lyoko.

"Odd and Yumi are in trouble. They're frozen," Aelita reported. "And Oulrick is losing life points fast. His doubles have already vanished."

Jeremy gasped in terror. His friends were in serious trouble. And he couldn't do a thing about it. If they were sent back to the real world, then Aelita was defenseless. And she would be destroyed and never brought to the Earth from the savage, virtual world known as Lyoko.

They were in the polar region of Lyoko, so Jeremy suspected that at least one of them would indeed freeze. But instead to his horror, two were frozen. And it would be thirty more seconds till they thawed. And Jeremy had to force the gears in his head to crank and spin till they made a light bulb go 'PING!.' And this stress was doing his light bulb serious damage.

But then, he got an idea as his fingers began clanking madly on the keyboard in front of him. This trick had saved them more than once. And he had to call on it again in order for it to do it's job.

Normally, this trick was used to call off guardians that would hold them captive. But now, it was going to be used as a decoy while his friends made for the tower to temporarily shut down Xana.

Xana was the virtual being that was never seen in Lyoko, but commonly possessing real world items so they would reek chaos and destruction.

Jeremy typed faster in fear of his friends till a virtual clone of Aelita appeared a few miles away from the four teenagers in Lyoko. Meanwhile, in Lyoko.

"What's taking Jeremy so long?" Oulrick asked as he took down another wasp. "We should just make a break for the tower." "No. He'll think of something," Aelita said. "The question is what is he doing?" Aelita thought privately while jumping away from a beam that had originated from a block.

It appeared to be an army of Xana's creatures surrounding of them. Herds of insects, dozens of wasps, squadrons of blocks, and a handful of tanks. These were all a select few of Xana's artillery of virtual creatures.

And they were all after one thing. Aelita. Without her, they couldn't deactivate towers and prevent Xana from escaping into the real world. Aelita was the only one who knew the code, and more importantly, do it. Only a virtual being can deactivate the towers. Odd, Yumi, and Oulrick couldn't because if they did, then they wouldn't be able to return to the real world.

But suddenly, they retreated. As if something even more powerful had arrived. They all ran in the same direction towards a glacier as if they had a certain purpose there.

"What happened?" Oulrick asked while the army ran even faster and Yumi and Odd thawed out.

"I created a virtual clone of Aelita," Jeremy said with glee, and everyone applauded. "We couldn't have done it without you, Einstein," Odd said, That was his nickname for Jeremy, on account of Jeremy being a child prodigy.

The four cheered some more, but then remembered why they were there. They had to prevent Xana from launching a rocket and punching a hole in the atmosphere.

The four began at a jog towards the tower, but it eventually turned into a run until they were standing at the base of the tower, and Aelita approached the tower.

"Do your thing, Aelita," Yumi said as Aelita went through the base of the tower. And about thirty seconds later, Jeremy's voice sounded into the air "Return to the past now," and a wave of white light exploded from the tower as Yumi, Odd, and Oulrick were swallowed by it, and thrown into the past along with Jeremy who was lifted from his seat and into the time frame with his friends who were being materialized into the real world.

"Does anyone have any questions? Ok, good," Jim said making the group of boys drop to the ground and do fifteen pushups without stopping. Jim was their strict physical education teacher at the boarding school they had all been sent to.

Jeremy dropped to the ground and managed to get out of fifteen by only doing five and making them seem abnormally long. Jeremy's brain was built for that kind of situation. A problem solver, deceiver, and all around genius.

Odd and Oulrick however, managed all fifteen. The were built for activities that took place in the physical world, not the mental. Stuff such as skateboarding, rope climbing, and of course, combat in Lyoko.

Yumi was sitting on the bleachers watching the boys struggle with their exercises. This was her free period, so she had finished school for the day. She could have done as much as the boys down on the field. She wasn't miss prissy. Yumi was actually a tomboy.

Unlike her least favorite person, Sissy, who was always trying to charm Oulrick into having a crush on her instead of Yumi. But it never worked on account of Oulrick hating Sissy too.

Yumi was tall, wore leek sheik clothes (which were black), black boots, and had short cut, black hair.

Odd was like his name. Odd. He normally wore purple clothes with a red-violet undershirt, had blonde hair, and a violet splotch on the middle of his hair.

Oulrick wore camouflage colors. A dim yellow shirt, forest green vest and pants, and he had chocolate brown hair.

Jeremy also had blonde hair like Odd, but unlike Odd, he had thick, black glasses. Along with that, he commonly wore a blue sweater with forest green shorts.

And now, the three boys were stuck in last period doing exercises for Jim. Odd was thinking about his puny dog, Kiwi, Oulrick was thinking about Yumi, and Jeremy was thinking about Aelita.

Jeremy had been working on Aelita's materialization for nearly a year now.

He would like nothing more than to see Aelita in the real world. To take a walk with her in the moonlight. To have dinner with her at a romantic restaurant. He had definite feelings for Aelita. He wanted his first actual kiss to belong to her. And that is why he had made it his life's work to bring Aelita to the real world.

Jeremy's thinking was interrupted by the vibration of his pocket. He reached in and pulled out his cell phone to see a text message that read "JEREMY! HELP!!!!"

His stomach immediately took a dive when he read the sender was unknown. It could be a trap set by Xana, or Aelita could be in danger. But she had never contacted him on his cell phone.

Something was wrong. And he had to find out.

"Uh, excuse me Jim. I don't feel so well. I have to go to the infirmary," Jeremy said, and Jim leered at him. "Fine, but hurry up," he said.

"And I would like Odd and Oulrick to escort me," Jeremy said, and Jim nearly exploded. "You know what, fine! Anybody else that needs to be excused from my class?" Jim asked impatiently, and Jeremy shook his head, "Uh, no sir," Jeremy snickered while Oulrick and Odd got up and assisted Jeremy to the infirmary.

"Is something wrong on Lyoko?" Oulrick asked, and Jeremy nodded. "I got this message," he said holding up his cell phone, and they both stopped to let Yumi catch up.

"What's up?" she asked, and they showed her the cell phone. "Do you think it's Xana?" she asked, and Jeremy nodded. "Either he sent this message, or he's put Aelita in danger," Jeremy said, and they changed their course to the sewer.

Yumi opened the sewer lid in the clearing of trees as they all slid down with the same question hovering in each of their heads. "What is going on?"

(A/N) Thanks for reading this far so far, and please review. Who sent the message to Jeremy? Is it Aelita? Xana? Or is it something else?
Please review while I write the next chapter.
