The is the sequel to Code Lyoko meets Reboot

The Return of the past


Last time

Jeremy and the others fought Xana's monsters, the Lyoko sprites hid behind a rock as they watched the battle. Suddenly a bright red light shot out of the cave and towards the Lyoko gang. They managed to dodge the blast and turned to see a female version of Xana with two small hilt katanas in her hands. Her bright green eyes glowed in the darkness.

The Lyoko sprites eyes went wide and thier jaws opened wide. They knew it was her. Thier sister, Delita. Out of the she stepped and walked into the light.

The Lyoko gang saw thier faces and knew that it was Delita.

"Is that Delita? She looks just like Xana." said Odd,

"They must be twins." said Yumi.

"Correct, Yumi." said Delita,

"How do you know my name?" asked Yumi.

"My brother has told me all about you. At first I thought my brother was losing his edge, but now it seems he may have underestimated you." said Delita,

"We're too good." said Odd, smiling.

"Sir, our new equipment is here." said the man,

"Good. How is our new program?" asked Drake.

"It should be operational within in the hour, sir." said the man,

"See to it that it is operational on schedule." said Drake.

"Any idea how to deal with Xana and Delita?" asked Jeremy,

"We could try to put them back into cyber sleep, but we have to find out how Xana reawoke first. If someone did wake him up then we have to deal with them. If Xana found a way to reawake himself we have to know how he did." said Relita.

"Ulrich if you wish for Yumi to live then you will place these cuffs on her." said the figure.

"No!" said Ulrich,

"I did not say you had a choice in the matter." said the figure.

It pressed its gun against Yumi's head. A single tear escaped Yumi's eyes.

"Yumi place your hands behind your back." said the figure.

She looked at Ulrich. He nodded telling her to obey.

"I will not ask again." said the figure.

She placed her hands and Ulrich walked to them. The figure grabbed her shoulders and turned her around. Ulrich took the cuffs and placed them on her hands. The figure nodded.

"Now Ulrich if you do not want to see your friend die, then stand still and do not resist. The rest of you sit on the ground and place your hands behind your back. I will release Yumi but she will also sit or I will shoot." said the figure.

They all nodded. Ulrich stood as a figure walked up behind him and grabbed his arms. It placed them behind his back and cuffs binded his wrists. It then pushed him to the ground.

Yumi landed beside him. She looked frightened. Ulrich leaned and kissed her on the cheek.

"How sweet. Even near death you still find comfort near each other." said the figure.

It turned to Odd, Jeremy, and Aelita.

"Sit or I will shoot them." said the figure.

They sat down, placed thier hands behind thier backs. The other figures moved towards in, they placed cuffs on thier hands.

"What do you want?" asked Ulrich,

"No questions or you will be killed." said the figure.

Then they grabbed thier legs put shackles on thier ankles to stop them from getting up and running. The first figure nodded.

The sound of tearing tape could be heard. The figures placed tape thier mouths. Their vision was completely obscured by the blindfolds placed over thier eyes. They pushed them onto the ground and searched them, also avoided Yumi and Aelita's private areas until they found thier cell phones. The sound of the phones being crushed could be heard.

The figures picked up the Lyoko gang and put them in the truck.

"You will not be harmed as long as you cooperate. You will now feel a slight sting, but no harm." said the first figure's voice.

They all felt something being injected into thier arms. They all started feeling dizzy and then fell asleep.

"Looks like that door could be hiding something important to them." said Jeremy,

"Let's see." said Ulrich.

They blasted through the door and saw what was inside. It was a giant supercomputer, with six scanners, and two chairs. When they saw who was in the chairs, their eyes went wide. Yumi and Aelita were strapped to the chairs; their skin was nearly completely white, their eyes showed no sign of life. There was a helmet attached to their heads that glowed a yellowish tone.

"I have been waiting for you." they said in an emotionless tone,

"Who are you?" asked Odd.

"My name is Chaos. I am speaking though you friends. They are currently somewhere else." said the girls,

"We have to get them out of there." said Ulrich.

"I may have an idea." said Jeremy.


Chapter 5

The Factory

Jeremy sat at the computer typing fast. Ulrich and Odd stood behind him watching, they all hoped Jeremy's plan would work. Jeremy had found a way to hack into Chaos's systems, but he had move slowly or Chaos would detect him.

"Jeremy what exactly is your plan?" asked Odd,

"The world Chaos created is a complete simulation. Only Yumi and Aelita don't know that it is a simulation. Chaos programmed the simulation so you could feel pain. That's the reason Yumi and Aelita started bleeding when Chaos sent those goons on them.

If we try to get them out of the chairs while they are in the simulation it could trap thier minds and the simulation would shut down taking them with it. And Chaos could kill them in the simulation. If thier minds are killed in the simulation then they die in the real world. It is just like the world Xana created to trap you and Yumi, except there are no glitches in it.

Chaos programmed it very carefully. Also Chaos is keeping a close eye on them. It hacked and looked up the info for every person in the city to make sure Yumi and Aelita did not suspect anything. It also created replicas of us in the simulation to keep a close eye on Yumi and Aelita." said Jeremy.

"So Chaos doesn't want any problems in its plan. But why did Chaos trap Yumi and Aelita when it could have trapped all of us?" asked Ulrich.

"I don't know the answer to that question. I also found out Chaos can inhabit one of the characters. Just incase something happened it did not predict in the simulation it could use the character to investigate the problem." said Jeremy,

"Next question, how do we save the girls with Chaos keeping a close eye on them?" asked Odd.

"I found a way to send one of us into Chaos's simulation. It's just like the program I used to get into Xana's fake school to warn you guys." said Jeremy,

"I'll go in. You need to keep an eye on Lyoko just incase Xana takes advantage of this." said Ulrich.

"I'll need to virtualize you in place away from Yumi and Aelita's location so Chaos does not suspect anything." said Jeremy,

"What if Chaos detects Ulrich?" asked Odd.

"There are a lot of characters in the simulation. They are not the humans in Xana's world. They were just recordings; these ones have thier own programming. They behave just like humans.

They are too many for Chaos to keep track at once. If Ulrich is virtualized at a safe distance he could find a way to warn Yumi and Aelita." said Jeremy,

'There is only problem, Jeremy. Chaos is keeping a close eye on Yumi and Aelita. How do I get close enough to warn them without Chaos sending its thugs?" asked Ulrich.

"I should be able to that. I'm going to send a virus to distract Chaos. It should give you enough time to warn Yumi and Aelita of what trouble they are in. But you'll have to be quick or Chaos will have you trapped like mice in a maze." said Jeremy,

"What if Chaos has already taken over one of the characters when I get there?" asked Ulrich.

"I wish I had the answer to that question, Ulrich." said Jeremy,

"One more question; what happens if I run into Chaos in a character form?" asked Ulrich.

"Chaos's world is not completely like Xana's; if it is in a character form it can only resort to fighting like a human. If the simulation was created for you to feel pain, then Chaos would also feel pain if it was injured." said Jeremy,

"Okay. I'm going in." said Ulrich, walking to the elevator.

"Ulrich. You are Aelita and Yumi's only hope now. Bring them back safely. And be careful, if you die there you die in the real world." said Jeremy,

"I will. I promise." said Ulrich.

The elevator closed and headed down to the scanner room.

"Good luck, Ulrich." said Odd over the intercom.

Ulrich put his thumb up and smiled as the scanner closed.

"Transfer Ulrich."

"Scanner Ulrich."

"Virtualization!"

Ulrich flew up and vanished in a flash of light.


Chaos's world

Ulrich appeared at the city limits. This was a safe distance? Well Jeremy as not been wrong yet. All he had to do was wait for Jeremy's virus to distract Chaos.

He felt that he was actually in the real world. He could breath, and he could feel the air. Jeremy was right when he said Chaos programmed this world very carefully.


The Factory

Jeremy started typing fast after Ulrich was sent into Chaos's world. The virus was ready and Jeremy uploaded it.


Location Unknown

Chaos watched Yumi and Aelita very closely. They were in the infirmary, recovering from the attack it sent on them. It was so amused by the pain Yumi and Aelita endured from its attack. With Jeremy, Odd, and Ulrich back at the factory with no knowledge of the location of its headquarters.

It would be smiling ear to ear if it was human. Why didn't Xana ever think of this it will never know. It wondered if Xana was becoming human. If he was than it would destroy him along with the Lyoko brats after it was finished toying with them.

Suddenly it felt a strange presence. It started scanning and found a virus infecting the simulation. It had to work fast if it wanted to keep Yumi and Aelita trapped where it wanted them. It knew leaving Yumi and Aelita unchecked was a risk.

But it could not risk leaving the virus to destroy its simulation. It ordered the Ulrich, Odd, and Jeremy clones to keep an eye on Yumi and Aelita while it dealt with the virus. It took over on of the characters and looked for the virus.


City limits

Ulrich noticed the buildings getting fuzzy. Jeremy's virus must be at work. He took out a black box and changed into his Lyoko form. He decided to move through the shadows.

Anyone of these humans could be taken over by Chaos. He moved through empty alleys and headed for the school. As soon as he saw the school he noticed Jim running out of the school and saw the factory. It looked fuzzier than the other buildings.

That must be where the virus is, and Chaos must have taken over Jim's body. He ran into the school grounds. He knew that Yumi and Aelita were in the infirmary recovering from Chaos's attack on them. He ran through the halls to the infirmary.


The Factory

Jeremy monitored the virus as he knew that Chaos would not risk it running free to destroy its simulation. The computer showed that Chaos had taken over one of the simulation's characters and was closing in on the virus. That computer was taking the bait.


The Simulation

Chaos closed and found the virus. It could easily erase the virus but it wanted to know how it got. It trapped the virus and traced back to the factory. It suddenly knew what was happening.

This was a diversion. It knew what to do. It left the characters body and scanned the simulation and deleted the virus. It found another Ulrich in his Lyoko form at Kadic Junior High.

It was looking forward to this surprisingly. It was getting bored with keeping an eye on those two brats. This could be a challenge.


The infirmary

Yumi awoke to find Aelita in a bed next to her. She looked and found that she was in the infirmary. She saw Ulrich, Odd, and Jeremy sitting chairs asleep. She felt something strange and noticed the wall was fuzzy.

Ulrich, Odd, and Jeremy also looked fuzzy. It was like they were in the same fake school Xana created. She shook Aelita and woke her up.

"Aelita, I think we are Xana's fake school." said Yumi,

"What makes you think that?" asked Aelita.

"Everything is fuzzy like the distortions in Xana's world." said Yumi.

Aelita looked and saw the distortions. She agreed and nodded.

"We have to find a way to contact Jeremy." said Aelita.

As she said that another Ulrich in his Lyoko form opened the door.

"Ulrich?" asked Yumi, looking at him and then other Ulrich.

"Yumi, we have to get out of here. You and Aelita are trapped in a simulation." said Ulrich,

"How can you be sure? How do we know that this isn't another one Xana's tricks?" asked Aelita.

"We were all abducted by Drake's goons. Remember?" asked Ulrich,

"I thought that was a bad dream." said Yumi.

"You wish. You are in a simulation created by a computer called Chaos. Jeremy helped me get here by using the scanners. Remember when he used the scanners when Xana trapped us in his virtual world." said Ulrich,

"You have a point. But if this is a simulation then how come me and Aelita were in pain?" asked Yumi.

"Chaos took your minds into this simulation. Your bodies are in the real world. Chaos programmed you to feel pain." said Ulrich,

Yumi and Aelita looked at each other, and then back at Ulrich.

"We trust you Ulrich. Now let's get out of here." said Yumi, noticing that the distortions were stopping.

"Why are the walls turning back to normal?" asked Aelita.

"Jeremy uploaded a virus to distract Chaos while I get you out of here.' said Ulrich,

"That will not happen." said the other Ulrich.

It stood up, its eyes were emotionless but its lips were curved into an evil smile.

"I had a feeling you would come to spoil my fun." it said,

"Chaos." said Ulrich.

"Don't be so modest Ulrich." said Chaos through the fake Ulrich.

"So you figured what Jeremy and I were doing?" asked Ulrich,

"After I trapped that little virus of his. Clever plan, but I am always one step ahead of you." said Chaos.

"One problem. Did you not know that Jeremy also hacked and found for Yumi and Aelita to escape your simulation?" asked Ulrich,

"There is no way that brat could have hacked that far into my systems." said Chaos.

"Jeremy is smarter that you think." said Aelita,

"That is true. But he was not smart enough to know that I anticipated your little rescue." said Chaos.

"Are how going to stop us?" asked Ulrich,

"Is that rhetorical question?" asked Chaos.

The room suddenly changed and they were in the factory. Out of nowhere came the characters of Chaos's simulation. Chaos in Ulrich's form stood in front of them smiling.

"Any last words?" asked Chaos,

"One moment." said Ulrich.

His sword glowed blue and fired a beam of energy and Yumi and Aelita. When the light was gone they were in thier Lyoko forms.

"Attack!" shouted Chaos.

The characters ran at them. Yumi threw her fan which sliced through, most of them. Ulrich ran at Chaos with his sword. Before he could strike a sword appeared in Chaos's hand and he blocked it.

"You didn't rally think I would leave myself opened to attack, did you?" asked Chaos, in a mocking tone.

Ulrich smiled at Chaos. It did not know what was so funny until it felt another presence behind it. It turned and saw Aelita swing her sword. Chaos disappeared and the fake Ulrich collapsed.

"You enjoyed that didn't you?" asked Ulrich,

"I was just letting of some steam. I hate programs that mock Jeremy." said Aelita, smiling.


Location Unknown

Chaos scowled, unconsciously. It manged to separate from the fake Ulrich before Aelita destroyed it. However it did feel pain from that sword. It made a note to make a program for it not feel pain when it inhabited one of the characters.

It could not be injured. But it did leave a mental scar on it. It knew that Jeremy had somehow discovered the way out of its simulation. It had to move fast before Ulrich led them out.

It had now had enough time playing. If it wanted to kill them, it had to stop them.


Chaos's simulation

"So how do we get out of here?" asked Yumi,

"By shutting down the super calculator in this world. It's Chaos's power source that keeps this world running." said Ulrich.

"Then we better hurry." said Aelita.

Xana's monsters started appearing.

"It is just no fun without them is it?' asked Ulrich,

"Run!" shouted Yumi.

They ran for the elevator as the monsters fired at them. The elevator stopped and opened to reveal the computer that held Lyoko. They each placed one hand on the lever and pulled it down as Xana's monsters blasted through the door and fired. The entire world became nothing but virtual lines then vanished.


Location Unknown

"NOOOOOOOO" shouted Chaos.


Somewhere between Earth and the simulation

Ulrich was pulled away from Yumi and Aelita by some force and was sent right back to the scanners in the factory. He stepped out and collapsed.

"What a ride." he said.


Drake's headquarters

Yumi and Aelita awoke find themselves strapped to a chair.

"Hey guys." said a voice.

They turned and saw Jeremy and Odd walking to them.

"How did you get here?" asked Yumi,

"We used the scanners to transfer ourselves to the scanners here." said Jeremy.

"Less talking more moving. We have to move before Chaos and Drake gets us." said Odd.

They untied the girls and ran for the scans. They entered and where sent to the factory. When they arrived they found an unconscious Ulrich. Yumi picked him up carefully and they entered the elevator going up to the computer.

Jeremy walked to the computer and scanned.

"Chaos's simulation has been completely destroyed. But the strange thing is Xana and Delita did not do anything while we rescued you. It seemed like a perfect moment to attack." said Jeremy,

"Unless sending us into Chaos's world was a distraction." said Yumi.

"One thing is for sure. Chaos is still alive. Its computer does not hold a virtual world like Xana's computer does. There is a section on Chaos's computer that is protected by a firewall.

I could try to hack in and find out, but it could take a while to delete the firewall." said Jeremy,

"Let's just get back to school. Ulrich needs his sleep." said Yumi.

"Always looking out for your boyfriend." said Odd.

Yumi glared at Odd, telling him to back off before he gets into trouble. They went into the elevator and headed back to school.
