I don't own Harry Potter or Code Lyoko Evolution

Enemy Mine

Harry, please, come to me.

Harry rubbed his head as the words flitted through his mind. Xana had tr try now, didn't he?

"Xana attack?" whispered Jeremy as the teacher droned on.

"No. But something is whispering to me. I think it's Xana," Harry whispered back. "He wants me to go to him."

"Don't listen then."

"You try to ignore something in your head. It's not easy."

I know you have no reason to trust me but this is important. It concerns Lyoko. It's important.

"And you can shut up," Harry muttered back. "How do I know that you're not trying to lure me to Lyoko so you can take me as a puppet?"

Silence. Harry turned back to the board as he tried to forget.

"Hey, Harry, could you give me some help on a program I'm working on?" asked Laura as the class left.

"Uh, sorry Laura but I have things to do. Homework, you know," said Harry as he walked over to his friends. "Hanging out with friends. Programming things. Things like that."

"What's this about Xana talking to you?" asked William as Harry sat down and pulled out his laptop.

"I don't know how he does it or why but I need to check Lyoko. Xana wanted to talk to me about it."

He connected to the supercomputer and frowned as he checked Lyoko. "Nothing there. Perhaps I should check the programming…."

He pressed a few keys as Jeremy and Aelita looked over his shoulder.

"That isn't normal. It's like Lyoko is dying or something."

"What?" asked Ulrich as he looked at the screen. "You know that coding doesn't make any sense to me Harry."

"Well, you know what a bug is right?"

"A bit of malfunctioning code?" asked Yumi. "If that's what you're thinking of."

"Well, a code that causes unexpected errors anyway. Lyoko has suddenly become full with them."

"Not good," said Odd. "Without Lyoko, we can't fight back against Xana. Though he won't e able to reach us."

"I could always reprogram it," said Harry as he wiped his glasses. "But the supercomputer could become damaged. I'll need some time to work on it."

"You can do it once school is out, right?" asked Aelita. Harry nodded.

"This is really annoying," said Sissi with a sigh. Everyone fell to the ground as the surroundings shook.

"Harry, forget what I said and get going to fix it," said Aelita. Harry nodded before trying to stand up and falling over. He slipped into Sissi's shadow.

"This is getting bad," muttered Harry as the shaking stopped because of a patch. "I thought that Lyoko could only affect the real world through the use of a tower. What is up with the computer?"

He shook his head as he fixed up what he could. "Hmm, looks like I'll need a program to restore Lyoko to a previous point…"

Flipping through his collection of discs, Harry found the ones he needed and started to connect his laptop up. "Just need to get this data entered then I'll have to make a trip to the core…"

Making sure that the virtualisation program was running properly, Harry started up a delayed virtualisation before running to the scanners and stepping into one.

"I hope Harry gets this fixed," said Aelita as she helped bandage a younger kid.

"Harry is very good at a lot of things. He'll think of something," said Luna dreamily. "Even mortal enemies can band together for a common cause."

"Are you suggesting that Xana might help Harry out?" asked Jeremy as he fixed a trail of wires down.

"Xana has much to lose if Lyoko breaks down."

"I'm going to see if Harry wants any help," said William as he strewed. "I don't trust Xana not to take advantage of the situation and turn on Harry."

"Sure, I'll come too," sad Odd as he stood up.

"So will I," said Ulrich has he also stood up from the rubble. A plume of smoke shot up from a distance away. "This place is going to hell. We need to get it sorted out."

Lyoko

"Ok, what do you want Xana?" Harry looked out at the empty landscape before sighing. The forest was always calming.

"I have a feeling your already know. Lyoko is destroying itself." Harry tensed slightly as he felt a hand on his shoulder. "We both know what will happen if Lyoko is destroyed. I won't be able to retrieve my source codes and you won't be able to access the place where I'm hiding."

"I worked that part out." Harry sighed as he closed his eyes. "The damage seemed to be mostly focused in sector five, around the core. We should have a look there. And we'd better hurry."

Harry sensed Xana smile. "Don't get any ideas. It's more an alliance of mutual interest than anything else. Though, if you really must, you can try to manipulate me."

He pulled himself out of Xana's grip as he headed towards the edge of the sector. There was pause before he heard footsteps follow him.

"What's happing on Earth?"

"It's going to pieces. There was an earthquake. Did anything happen on Lyoko that you noticed?"

Xana remained silent. Harry glanced at him before shaking his head. Xana had to pick his body out of all the possible options. Reaching the edge, Harry touched the terminal.

"This wasn't here before."

"I added it when I recreated Lyoko. It just makes it easier to summon the transporter."

Scipio flashed on the terminal and the transporter scooped the two up.

Kadic

"First an earthquake, now torrential rain?" asked Aelita as they looked out the window. "Things must be going bad."

"Harry did apply a few patches," said Jeremy as he frowned at his laptop. "The bugs seem to be more like pieces of code being deleted than anything else."

"Really?" asked Yumi. "Do you think Harry will find the source?"

"I don't know."

"What are you talking about?" asked Laura as she walked over. "Is Hurry doing something to help? I haven't seen him for a while."

"Yes, he's trying to sort this out," said Jeremy as they shared as glance.

"And before you ask, you don't need to know," said Yumi as Laura opened her mouth again. "It's a secret."

The glass began to crack and the group nervously moved away from it.

"The rain's getting stronger," said Jeremy. "If this keeps up, the area will flood."

Lyoko

"This isn't good," said Harry as he looked at the ragged edge of a hole. "Not good at all."

He examined the edge closely.

"We don't have time for this Harry." Xana's voice was urgent.

"I recognise this though. It's like someone fired a reductor at it." Harry shook his head. "I just hope Dumbledore hasn't found a way to get here without the scanners. That would be bad."

Jumping over the hole, Harry landed lightly before navigating the labyrinth and reaching the celestial dome.

"Harry?"

"Hey William. How is it going on earth?"

"It's pouring it down at the moment. I think you need to get on with whatever you're doing. Do you want any help?"

"Yeah, we could offer some back up," said Odd eagerly. "Amy amount of help could be useful."

"Oh, you just want to fight," said Ulrich as he nudged the boy. Odd made a face at Ulrich.

"I don't think that anyone else should come over," said Harry with a head shake. "There's a risk that it could cause Lyoko to determinate faster. Can you keep an eye on how Lyoko is please? Oh, and change the disc over. It contains a restore point for the sectors."

"I think I can do that."

Glancing at Xana, Harry frowned. "You're quiet. What's up? Normally you'd be trying to get me to join you."

"There is something worse than me wanting you. Me losing access to you." Xana shook his head.

Harry closed his eyes as he jumped off the edge and flew around to the valve protecting the access point to the core of Lyoko. Flying past it, he landed next to the switch and hit it as Xana landed next to him. Running up the pathway, they stared at the core of Lyoko.

"That's not good." The area was being lit up by various lights. The shields had gone down to five.

"Five out of ten shield layers have gone." Xana frowned. "That's not good. Considering the amount of power I would need to destroy one…"

"With the way I designed them, they should be able to stand up for ages yet. When a shield layer is destroyed, its power goes to the other ones." Harry started to climb up quickly as he spoke.

"Harry, I think you need to hear this." William's voice was nervous.

"No one know the cause of the sudden environmental changes that have swept the region. Torrential rain has caused rivers to burst their banks. The government is urging people to stay inside until the rain stops."

"I think you need to hurry up Harry," said Odd slightly nervously. "We're right next to a river."

Grumbling, Harry reached the core level. "I should have known it was you Dumbledore. What are you doing?"

"If this place goes, you have no reason to stay here. That means I can bring you to Hogwarts without any interference."

"Yeah, and you'll be my best friend and we'll have adventures together," said Ron in glee. "Then you'll give me some of your money and I won't live in poverty anyone."

"That is lame," said Harry after a second. "What makes you think that I'll go to you? And if this keeps up, we'll fall into the digital sea. I know I won't disappear but I have no idea what it does to humans. How on earth did you get here anyway? Lyoko doesn't exist in the real world, it's a computer program. And there's no atmosphere here. I understand that you want to get out of poverty but you can't just ruin another's life to get out of it."

"A rather complex piece of magic. And, now if you excuse me." Dumbledore sent another reductor at the shield layer. Harry knocked him down as Xana faced Ron.

"Who the hell are you?" asked Dumbledore as he saw Xana.

"I am many things. I'm not Superman or Batman or Spiderman or Aquaman or merman or wolfman or Brahman or common or ramen or caiman. You could say that I'm no man."

"Literally, you are no man," said Harry with a grin. "You're not even human. Now, got any ideas how to send these guys back?"

Dumbledore sent a reductor into Harry's chest who landed on his feet and raised an eyebrow.

"Be careful Harry, you just lost 20 life points."

"Ok, I'm going to get out the big guns. Or rather, big sword." Said sword appeared in Harry's hand before he tried to slice Dumbledore's arm off. It just flickered. "Oh, you're just a projection that can interact with Lyoko. Then if I stab you in the heart or the brain, then you'll go back."

He shot forward and stabbed Dumbledore in the head who just flickered.

"I'm afraid you will have to do more than that Harry."

Harry ducked the curse sent his way. "You have to stop sending magic out. The real world is suffering here. By damaging Lyoko, you harm the real world."

"You're lying."

"He isn't." Xana's voice was low. "There's a torrential downpour in the area surrounding the computer. If this keeps yup, the buildings will collapse into the mud. People will die. Normally, I wouldn't care but I'd much rather have the containers of my power alive than dead."

The water lapped at the window.

"This is getting worse," said Yumi. "Something tells me that Harry is having serious problems here."

Jeremy wiped water off the screen of his laptop. "He's on Lyoko. I think he's working with Xana to get some results."

"I said that even mortal enemies can work together." said Luna dreamily. "Even Harry and Xana."

"As long as they don't end up friends, that is," muttered Sissi.

"Well, I think they'll return to normal eventually, if we survive this," said Aelita.

"Who's Xana?" asked Laura curiously.

"No one you know," said Aelita. "And you don't need to worry about him."

"I think you will need to tell someone about what you know," said Laura as she folded her arms. "They could…"

"Do what?" asked Yumi as she sent the girl a look. "Harry knows what he's doing. And what can anyone do about it anyway? We can't get anywhere."

Lyoko

"You got any ideas on how we should get rid of these guys?" asked Harry as he created a rope to wrap around the two's hands.

"I suggest you do whatever you need to do here first." Xana gestured toward the core. "You know how you programmed it better than I do."

Harry touched the terminal and started uploading the program he stored in his avatar.

"This should stop the core getting any worse. I'll have to manually repair Lyoko. That's a job and a half." Harry closed his eyes as Xana poked Dumbledore's nose.

"You know these guys?"

"I was wondering about that too," said William.

"Yeah, they keep popping up and try to get me to their school. It's annoying." Harry stared at the sphere which started to repair itself. "Oh, I forgot I included a repair feature in it when I recreated Lyoko. It won't do anything under repeated assault but it will regenerate given a chance. I'll need to do since realist though."

Seeing something shining out of the corner his eyes, Harry studied the amulet around Dumbledore's neck. "So that's it. Oh, Xana, do you think you can find something like this on Ron?"

Xana nodded after a second before roughly handling Ron, a strange look on his face. Harry swore that he was planning something nasty. Like a plan to hurt them or potentially kill them.

"Harry, whatever you're doing, I think you need to hurry up. The lab's leaking!"

Pulling out a Kunai, Harry stabbed the amulet and Dumbledore faded away. Glancing over, he saw Ron had disappeared too. Xana still had that strange look.

The rain started to relent as the sky cleared.

"Finally," said Yumi in relief.

"Well, I hope Harry sends us back in time," said Jeremy as he looked at the widening crack. "That won't keep up for much longer."

As Jeremy spoke, the window gave up and shattered. The water poured in to people's yells.

Lyoko

"Well, that's done," muttered Harry as he finished the last repair. "I guess I'll go back and do a return trip."

He could feel Xana's eyes on him.

"You know, if you weren't hell bent on taking over the world, we could be friends."

"Yes, I can see that happening. Just this once, I'm going to leave you alone." Harry turned to look at Xana in surprise. "I am capable of being nice once in a while. Besides, this gave me a chance to observe you closely."

Harry nodded slowly. "I think I get it. Yin yang. Even the darkest, evilest person has the potential for good and the opposite is also true, the purest, best person can fall to darkness. That means that people are neither good nor evil. What do you learn about me?"

Xana smiled as it faded away. Harry sighed and stabbed himself.

Lab

Harry waded over to the computer and started the return to the past. William sneezed and waved at him as the white light covered them. Odd cheered.

Earlier

"So, Lyoko won't go into meltdown again?" asked Sissi as they regrouped. "Because I don't want to have to hide from a torrential downpour."

"Nope. I protected it from that," said Harry with a sigh. "I still have no idea why the supercomputer started to launch an attack like crazy. Perhaps it was just reacting to what was happening in its systems."

The boy sighed.

"Anyway, what did Xana do?" asked Jeremy as he nudged the boy. "I saw that you were with a monster at least."

"Xana helped out. Apparently it was to observe me and Xana had just as much to lose if Lyoko went down as we did."

"I think that Xana does have a nice side to him, buried deep," said Luna dreamily.

"Or, he hopes that I would go to him if he acted nice to me," said Harry with a shrug.

"So, what about Dumbledore?" asked Odd. "Weill he try to destroy Lyoko again?"

"I hope not!"

They burst out laughing at Harry's face.

"You are really funny when you're not trying to be," said William as he calmed down. "Do you think Laura is going to continue to harass you?"

"I think she is. I don't like it though."

The said girl watched them from a distance and frowned. She knew they were hiding something but what? She shook her head. The only way to find out was to try and make friends with them though that seemed to be hard. They had such strong bonds between each other...
