I don't own Harry Potter or Code Lyoko

High Temperature

"And go!" ordered Jim as he blew the whistle. Harry winced at the high pitch as he started to run along with people he knew vaguely.

"I hate PE. It's too easy now," he muttered as he outstripped the rest of the runners.

"Nice going Stern," said Jim as Harry stopped. "You're not even winded. Have you been holding out on me?"

"I've been training in my own time," lied Harry.

"You have to join the running team," gushed Jim as he grabbed Harry. "We'll win the interschool events. We'll win everything!"

"Can I think about it?" asked Harry as he wiggled out of Jim's grasp.

"Of course."

Harry jogged back to his seat as Sissi snuggled up to him.

Lyoko

A tower in the forest sector glowed red.

Kadic

"Nice going Harry," said Ulrich as he leaned over. "Now if you go fast, people will assume it's because of your training."

"I'll still have to be careful though," muttered Harry as he rubbed his head. "I don't want people to find out about my powers. Xana's attacking by the way."

He sighed.

"What's up?" asked Ulrich.

"Just annoyed at the constant Xana attacks recently. Xana has been targeting me more and more."

Harry's and Jeremy's Dorm

"Hey Jeremy and Aelita," said Harry as he and Sissi wandered in. "How's the antivirus going?"

"It's frustrating," said Jeremy as he glanced at the two. "How was PE? Did your plan work?"

"Jim offered me a place on the running team. Xana's attacking by the way. You should take a break as well Jeremy. It's not healthy to be cooped up inside all the time."

"I'll run a scan. And as long as Aelita is connected to Xana, I can't take a break."

"Harry has a point," said Aelita as she put her hand on his shoulder.

"Hello boys and girl," said Odd dramatically as he slammed the door open. "Odd Della Robbia is here to cheer you up!"

"Did Ulrich put you up to this Odd?" asked Harry. Odd gaped at him. Sissi giggled at Odd's expression.

"I thought so. Anyway Sissi, is there anything you'd like to do?"

Sissi smiled as she pulled Harry out the door.

"There goes our best fighter," muttered Odd. "He's cheered up."

Aelita giggled and Jeremy sighed as he ran the scan.

Ulrich

"Hey Yumi."

"Where are the others?" asked Yumi as the couple walked out of school.

"All in Harry's dorm. Harry gave me some money to take you out! He also mentioned Xana becoming active again."

Ulrich winked at her. Yumi smiled.

"That's nice of him. There was a film I wanted to see."

They felt a breeze.

"Was that Harry and Sissi?" asked Yumi as they watched two people disappear.

"I believe it was. I think Sissi has shopping in mind."

Harry and Sissi

Sissi held the shirt against Harry and considered it.

"Remember your limit Sissi," reminded Harry.

"I know. €100. This would look good on you."

"I think you'd make a good fashion designer."

"You really think so?" asked Sissi as she looked at the clothes. "This is enough."

"I do."

They walked outside after paying. Sissi pulled him along to a shoe shop.

"You need a new pair of shoes. Yours are falling apart or they've been chewed on."

Harry frowned as he felt the heat.

"Is it me or is it getting hotter?" He knelt down and placed his palm to the ground. "There's something wrong with the ground. It shouldn't be this hot at this time of day."

"Xana?"

"Possibly." Harry looked at his watch. "We'd better get back to school Sissi. It's nearly time for tea."

Sissi pouted but dragged him back to school.

The next day

"Yeah, it was weird," said Harry as they walked into Ms Hertz' s class. "I swear that the ground was rising as well."

"The Superscan didn't pick anything up," pointed out Jeremy as they sat down.

"I'm sure it's nothing," said Aelita. "It could be your imagination Harry."

"Xana may be hiding the tower. Or he may have bugged up the program again."

"Alright, settle down everyone," ordered Ms Hertz. "Today, we are learning about volcanoes."

Herb glared at Harry. "What does she see in him?"

Harry glanced at him but didn't do anything else.

Hogwarts

Dumbledore groaned as Molly Weasley yelled his ears off.

"There's nothing I can do," he interrupted Molly's tirade. "I can't go and get young Harry as the French ministry has made it clear that I can't interact with Harry without a good reason."

"You can force him to come. He has to be Light."

Dumbledore sighed. "He always finds a way out. And now I'm the laughing stock of the world. There's nothing I can do."

Kadic

"Well, that was boring," said Sissi as they walked out the classroom. Harry frowned.

"I wonder…"

"What is it Harry?" asked Jeremy.

"I think Xana might be making a volcano under the town. Or storing a lot of magma there. Xana does seem to have a habit of using what we learn in science as an attack method."

"Be realistic Harry," said Ulrich. "We're nowhere near a fault line. Xana can't do that."

"A computer program can't possess people yet Xana does that."

"He has a point," said Odd as they wandered outside. Jeremy's laptop beeped.

"Hey guys," said Yumi as she walked over. "What's happening?"

"Xana attacking is what's happening," said Jeremy as he looked at the display. "The tower's in the forest sector."

Harry pulled out his laptop and opened the news channel.

"A build-up of magma has mysteriously formed under the town," reported the reporter. "The means of the magma appearing is unknown as the town is nowhere near a fault line. The army is evacuating the population away from the site as the pressure could cause the magma to come to the surface at any time."

They looked at each other.

"I was right," said Harry. "The warmth of the ground. It was the heat from the magma rising up through the rocks."

"It's sunny today," pointed out Yumi.

"This was last night," said Harry. "When the ground had time to cool."

"We need to get to the factory," said Jeremy. The ground vibrated and they saw a plume of lava.

"Uh oh."

They shot off towards the factory. The students looked at them strangely.

Factory

"Uh oh. Again."

They looked at the lava covered bridge.

"How are we supposed to get over that?" asked Odd.

"I could jump it," said Harry. "It's almost like Xana is trying to get me alone."

"There has to be a way around," said Aelita. "Harry, go ahead. We'll find another way around."

"And if you don't come and I deactivate the tower, do you want me to do a return to the past?"

"Of course," said Yumi. "We need to make the town safe again."

"You seven! Come with us. You need to be brought to safety."

"Oh no," moaned Ulrich as they turned to look at the soldiers. "Now of all times!"

"Go Harry," ordered Jeremy. "Get to Lyoko."

Harry nodded and backed up. The soldiers stared as he made the jump.

"You need to come with us."

They raised their hands and followed the soldiers.

Lab

"Here we are," muttered Harry as he looked at the coordinates of the tower. "Now to get myself over to Lyoko and deactivate the tower."

He set up the delayed virtualisation program and ran to the scanners.

Lyoko

Harry pushed himself to his feet and looked round.

"It's been awhile since I have been here on my own without any company. Not since we materialised Aelita and that was mostly before I found her."

He ran off in the direction of the tower.

Army base

"What do they want?" asked Sissi as they waited for the captain.

"They probably want to know what Lyoko is," said Ulrich. "And how Harry made that jump."

"We're doomed," said Sissi as she curled up to Ulrich. "My father is going to kill me."

"Don't worry," said Yumi as she rubbed Sissi's shoulder. "Harry will get us out of this. He hasn't let us down before."

"Yeah, but we'll have to tell them about Lyoko," said Jeremy sombrely. "And that would lead them to the fact that Harry has powers that most people don't and Xana. They'll shut down the computer and kill Aelita."

A tall man walked in.

"I am the captain of this unit. My men have told me a rather interesting story."

They gulped as one.

Lyoko

Harry frowned as he looked around warily. "Where are the monsters? I hope Xana hasn't sent a clone."

He ran over to the tower and groaned. "Speak of the devil and he will appear. A clone."

The clone smiled. "Finally. We are alone Harry."

"Will you please stop sending clones?" asked Harry. "I hate those things. I much prefer the monsters that don't talk. No risk of manipulations."

"But they are so very effective," said the clone. "The army has your friends. I can free them if you do wish."

Harry snorted. "At the cost of my freedom and the world's safety? No way. I can just deactivate the tower and return us to the past to set things right."

"I thought you would say that. That's why I thought of a plan b."

Several hundred Krabes appeared.

"That's a lot of monsters."

The clone pulled out his sword and pointed it at Harry's throat.

"I know. There's one more that I'm sure you're familiar with. As I see it, you have two options. One is attacking and getting devirtualised and the other is submitting yourself to me."

A screech echoed throughout the area as the clone grinned evilly. Harry shuddered.

"Is this just about my powers?" asked Harry. "If I'm going to end up under your control, I should know why. I'll also probably know anyway."

The clone looked pensive. "It's not just about your powers, no. thought they play a pig part of why I want you."

"And I guess my intelligence plays a part too."

Army base

"So that's your story, is it?" asked the captain. "That your friend has always been different and Lyoko is a video game?"

They nodded.

"I don't believe you. Take us to where your friend went and we'll let you go."

The group looked at each other.

"Stall for time," muttered Sissi.

"Why should we?" asked Yumi. "For all we know, you might not let us go. And there's Harry, he's scared because if anyone finds out, they will experiment on him."

"He's done an excellent job on hiding his abilities," said the captain as he paced the office. "But now he has to be brought in. He's too dangerous to be let loose."

"Harry thinks that as well," said Ulrich. "He hides his abilities so that they won't be used for the wrong reasons as well as for his own safety. But seriously? Bringing him in just for being able to jump a large distance? How is that dangerous?"

"He could commit a lot of crimes and easily evade capture. Take us to him."

"He's not a threat," said Jeremy desperately. "He just wants a normal life."

"How are we going to do that if we can't get to the factory?" asked Yumi.

"We will provide the means. Now, let's start from the beginning. Tell me exactly what Lyoko is. And cut the nonsense about it being a video game. I've checked and there's no game with that name."

They sighed and told him the truth.

"I just hope Harry deactivates the tower soon," muttered Ulrich. "Or we're doomed."

The volcano spurted again and the lava continued to cover the town.

Lyoko

The clone pushed Harry back towards the Scyphozoa as it floated over and picked him up.

"Just submit, like you did that one time. Remember the power that you felt."

Harry closed his eyes and remembered. He remembered him rejecting it for not being his own.

"Not like that."

"I don't want power."

His view of the world started to change as Xana started to control him.

"That's it. As long as you have nothing to fight for, it's rather easy to control you."

"NOT MY BABY!"

Harry lost consciousness.

Somewhere

Harry up and regarded his surroundings. It was Lyoko but it looked different. The towers were all glowing a light yellow and there was no digital sea. However as he looked closer, he could see dark patched appearing.

"Where is this place?" he wondered. "Lyoko?"

"Well, you could say that."

He whirled around as he looked at a women.

"You could also say that this is your mind. This is the place that your mind would look like if it was real."

"Mum?"

She nodded.

"How are you here? You're dead."

"Let's say that a person never dies, that they live on in a person's heart."

Harry frowned. "So you're made up of my memories of you."

She smiled. "You've turned into such a smart boy."

"Xana! What's happening?"

"That program has been taken control of your body He tried to get rid of your conciseness when he took control but I saved you for the time being. But he will try again."

"Tell me about it," muttered Harry. "I've lost count of how many times he's tried to possess me."

Lilly sighed. "That was my fault. I agreed to let Franz send you to Lyoko and Xana felt your potential. He tried to keep you there but we managed to bring you back. That's why Franz edited your avatar, so you'd be able to fight him off if you ever came across the supercomputer. You've resisted for so long."

Harry frowned as he heard crying. He looked at the source and flinched back. "What is that?"

"That is a soul fragment. It belonged to the wizard who killed me."

Harry walked over to it, pulled out his sword and destroyed it. It screamed. Harry rubbed his head as his mind felt clearer.

Kadic

The lava started to cover the campus as the students tried to run away. The arm helped them but the lava was advancing quickly.

Army base

"There's a supercomputer in the factory we found you at?" asked the captain as he tried to get all the facts. "And it contains a virtual world called Lyoko as well as a virus called Xana that wants Aelita's memories as well as total control over your friend?"

"That's right," said Aelita. "He placed a virus in me that links me to the computer. If it is shut down, I die."

The captain frowned. "Do you have any proof?"

"We'll have to show you."

Harry's mind

The darkness reached the platform.

"You need to regain control of your body," said Lilly hurriedly. "There isn't much time. I can't do what I did the first time again and that was only became I loved you."

"How?" asked Harry dejectedly. "It's so hopeless. Every time I repel Xana, he becomes more convincing. And now he's controlling me."

"The one thing Xana can't understand is a human's will to protect. You have people you want to protect, don't you?"

Faint images of Jeremy, Odd, Ulrich, Yumi and Sissi appeared. Harry looked at them sadly.

"I failed them."

Lily raised his head to look at them. "There is still hope. You're still here. You're the only one who has any right to be here. As long as you believe that, Xana can never destroy you."

She faded.

"Mum!"

"We'll meet again."

Harry reached for her but she had gone. The darkness pooled around his feet. He looked around wildly as the towers started to glow red.

"Finally. Total control will be mine. Just relax Harry."

He turned to face Xana. "Not if I have anything to say about it."

"You can't do anything. You've lost."

"I make the rules here."

Harry focused and the towers glowed brighter. Xana attempted to stop him but Harry made the platform disappear. The world returned to its normal state. Harry felt himself fade away as he returned to his body.

Factory

"Why is Harry taking so long?" whispered Sissi as they ran into the factory and wiped the sweat off their faces. "He's faster than this."

"He must have run into some problems," said Aelita as they led the captain to the elevator.

"Well?" asked the captain. Jeremy glanced at the lava which was beginning to pool into the factory.

"Xana must have made the lava cool down before sending it. "We would have burned to death due to the high temperatures by now otherwise."

"We're here, in the right place," said Ulrich "It's just a little further this way." They went down to the lab and the captain gaped at the computer.

"That's the supercomputer?"

They nodded.

"And where's your friend?"

"He's inside the computer," said Aelita. "He's existing as a computer program."

"How?"

They exchanged looks then looked at the door as the temperature rose.

"We're trapped! Harry, hurry up!" called Jeremy as Sissi hugged Ulrich.

Lyoko

Harry groaned and looked at the clone from where he had been dropped. The monsters had disappeared. He knew that Xana had tested him out on them as he could remember what had happened.

"So powerful. How did you manage to resist?"

"I had some help."

He stood up and charged the clone. It didn't managed to defend in time and it exploded. The copy still had a look of pride on its face as it disappeared. Harry walked over to the tower.

He rose to the second platform.

Harry

Code

Lyoko

"Tower deactivated."

He heard his friends sighs of relief.

"Now, bring him back and we'll sort this out," said the captain.

"Yeah, we'll sort this out," said Jeremy as he walked over to the computer and started a familiar program. "There's one thing we forgot to mention. Return to the past now!"

The program started and repaired the damages to the town.

Earlier

"Nice going Harry," said Ulrich as they met up after the science class. "You managed to save our skins."

"That was one deadly attack," said Aelita. "As well as a hot one."

"What took you so long?" asked Yumi.

"Well, there was this little matter of Xana Xanafying me and then I talked to my dead mum in my mind that was apparently made out of memories and then destroying a soul piece that was lodged in me."

"You were possessed?" asked Aelita. "And you're dead mum helped you?"

Harry nodded. Sissi hugged him.

"Well, at least tour secret is safe again," said Jeremy. "That was nice timing Harry. We were about to die by burning and you broke out of Xana's control."

Harry smiled. "As long as I have something to protect, I think I'll be fine."

"What about the running team?" asked Ulrich. "Are you joining?"

Harry nodded. Everyone hugged him.
