I don't own Harry Potter or Code Lyoko

Satellite

In the ice sector, a tower started to glow red with two hornets circulating it.

Class

"What do you get when two neutrons collide?" asked Mrs Hertz. "Anyone?"

Herb raised his hand. He was the only one.

"Yes Herb?"

Everyone's phone except Harry's went off since his was in his room. Harry clutched his head which didn't go unnoticed by Jeremy.

"Hello?"

"Hello?"

There was no one on the other end.

"Who is this?" asked Sissi.

"Sissi, as the principal's daughter, you should know the rules regarding phones in class! Care to remind us?"

"Uh, they should be turned off before entering the classroom. The penalty is that they'll be taken off you if discovered."

"Which means that they all have to be confiscated. Everyone's phone to be put on the desk."

Everyone reluctantly gave in their phone but not without complaints. The four boys looked at each other.

"Be quiet! It's your own fault for bringing them in switched on!"

"This is bad," Harry muttered. "We can't contact each other. Xana will be pleased."

"Harry, where is your phone?" asked Mrs Hertz, seeing that he wasn't moving.

"In my dorm."

The bell went.

Corridor

Yumi ran down the corridor to the right classroom and waited.

"Something really weird just happened," she said as the boys came out.

"The phones went off and got confiscated?" asked Harry.

"How did you know?"

"The same thing happened to us."

"All those calls and no one at the other end? I need to talk to Aelita. This could be Xana's doing," said Jeremy. "What do you think Harry?"

"Jeremy, it was Xana's doing! I felt him."

"We need to find a solution," said Ulrich. "Harry, can you pick locks with that energy of yours?"

"And lock them again. I think."

"Oh. Hello you five," said Sissi as she approached with her minions.

"What do you want Sissi?" asked Harry.

"I was just wondering if you'll help me with a petition for the phones to be returned."

"I will," offered Yumi.

"Good. Perfect, in fact. Meet us in the cafeteria after lunch."

"Let's go contact Aelita, Harry." The two walked off.

"There has to be a solution. A way to communicate without using mobiles."

Harry's and Jeremy's Dorm

"Aeltia, are you there?" asked Jeremy as he sat at the computer and Harry pulled out his laptop.

"Hey. What's up?"

"We think Xana's attacking. All the phones went off earlier but there was no one at the other end. Have you sensed any pulsations?"

"No. But I haven't been looking."

"Ok, I'll run the scan."

"I'll look for pulsations."

"Be careful."

"He's definitely out there," piped up Harry. "I can feel him. But the feelings are weird. It's both strong and faint, like he's trying to affect two things at once, one close and one far way. I just hope the tower isn't in the ice sector again. I'm getting tired of being in the cold when deactivating the towers."

Cafeteria

"Looks like the students needed to be reminded of the rules," said Delmas. "Jim, can you disable the antenna? That way, they can't call anyone even if they get new phones."

Jim nodded as he ate.

Well, that's Harry out," said Ulrich.

"I can try to force the lock," offered Odd.

"Wait, are you talking about stealing?" asked Yumi.

"It's not stealing, more like taking back what's ours," replied Odd.

"I'm staying out of this."

When the teachers were distracted, Ulrich and Odd slipped out as Yumi watched them.

Staff room

Odd slipped into the empty room as Ulrich kept watch. He quickly ran over to the right locker and pulled out a paper clip, straightened it and fiddled around with the lock before hearing a click. He pulled out the right phones before closing the locker.

"Hello Sir!"

Odd started to panic before hiding under the table. He watched as the teacher walked around the table, paused then walked back out. He quickly followed.

Harry's and Jeremy's Dorm

"Here they are," said Odd as he presented the three phones and placed them next to Kiwi.

Yumi walked in. "I see you got your phones. Let's hope no one finds out."

"The scan doesn't pick up an activated tower," said Jeremy.

"I don't feel any pulsations either."

"Looks like Xana isn't attacking then. False alarm."

Harry frowned. "I still feel Xana's presence."

"AH!"

They looked at Odd who pointed at the phone. The eye of Xana was on it.

"Xana!"

"Your program's faulty!"

"That explains the feeling I got was. Shall I go to Lyoko?" asked Harry.

"Not yet."

"Why would Xana be interested in mobile phones?" asked Ulrich.

"I think we'll find out by checking the antenna."

They walked out the room.

Roof

"Hey Jim."

"You're not trying to stop me disconnect the antenna, are you?" asked Jim.

"Err, no."

"That's good. Ah!" Jim yelled as he got an electric shock.

"Man. Smells like chicken. What have you been eating? Are you ok, Jim?" Harry asked.

Jim twitched.

Jeremy quickly hooked up the device and looked at the results. "The main TV antenna?"

Infirmary

"What happened?" asked Yolanda.

"He got an electric shock so we brought him to you."

"Ok. You can go now."

Harry left and mumbled, "I'm definitely going to Lyoko now. First I'm going to get my laptop."

Cafeteria

"Oh, Yumi is gracing us with her royal presence! Where were you when we wrote the petition?" asked Sissi.

"Sorry, I got delayed. I would have been here earlier but I needed to get something," explained Yumi.

"Just what is going on in here?!" asked Delmas as he walked in.

"Oh, Daddy. We all signed a petition so you have to give us back our mobiles," said Sissi.

"Oh is that all? First, let me remind you that the students do not make the rules. Secondly, Ms Hertz has just informed me that someone went into the staff room and forced her locker open to get back his or her mobile!" said Delmas.

"It's only normal, Daddy! How could anyone live without their mobile?" asked Sissi.

"I'm sorry but the theft is a reason not to return them to you. And we're going to investigate into who stole the phones."

"Well, I say we don't go to class until we get our phones back," said Sissi.

Yumi noticed Jeremy desperately trying to get her attention and slipped out.

Harry's and Jeremy's Dorm

"Xana's trying to use the school antenna to hack into the TV antenna," said Jeremy to Yumi, Odd and Ulrich as Harry walked in.

"That's why the phones rang?" asked Yumi.

"The frequency jammed the signal. If Xana is able to control the satellite for the TV dish, he'll be able to hack into other satellites too."

"Like a military one, preferably one that's already dangerous and reprogram it to be an even greater danger," finished Harry. "We'd better get to Lyoko."

"The scans found the tower."

"Jeremy, Xana's activated a tower in the ice sector. Please hurry."

"The ice sector. Why is it always the ice sector?" moaned Harry. "I swear he's activated a tower there for the last few attacks!"

"Let's go through the tunnel in the park."

They left the room.

"Kiwi, stay here," said Odd as he closed the door. Kiwi jumped at the handle and opened the door.

Outside

"No more phones, no more school," said Sissi as she walked in front of the students. "Perfect."

"I'll stay here in case Xana attacks the school," said Yumi.

"Hey are you with us or not?! Ever heard of solidarity?"

"I'm surprised you have," said Harry. "Especially with those two brain cells of yours." Sissi glared at him.

"Don't worry Sissi. I'm with you. No more phones, no more school! No more phones, no more school!" Yumi ran towards the others.

Manhole

"Kiwi? What are you doing here?" asked Odd as said dog walked up.

"For a dog, he's as stubborn as a mule," said Jeremy.

"Come on Kiwi."

Kiwi jumped onto Odd's arm as he climbed down the ladder.

Lab

"Aelita's on the way to the ice sector," said Jeremy.

"Well, duh. She was in the forest sector."

"Aelita?"

"I'm at the ice float but I don't see a tower."

"Ok. Wait for Harry, Odd and Ulrich. Watch out for monsters. Transfer Harry. Transfer Odd. Transfer Ulrich. Scanner Harry. Scanner Odd. Scanner Ulrich. Virtualisation."

Lyoko

"Here we are, the freezing wasteland," muttered Harry. "I swear I'm getting a phobia of this place."

"Hey guys."

"Hello Aelita. Where's the tower?"

"Xana's still not in control of the TV satellite. That gives us time. I'll try to find out what satellite he might target."

"You do that."

"Now for the access code. Access code accepted. Yes! The military really needs to upgrade their security."

"Not everyone has a supercomputer Jeremy."

"U4 66. A military satellite armed with… a highly destructive laser beam."

"Where can that tower be?"

"One thing at a time Odd. Xana's going to take over a satellite with a laser."

"That's bad," said Harry.

"The laser is highly accurate and destructive."

"That's even worse. Yumi! And the school!"

"What about her?"

"If Xana takes control, he can use it to shoot at her and the school. We need to warn her."

"Without a mobile, we can't contact her," pointed out Jeremy.

"Kiwi."

"What about Kiwi?" asked Jeremy, confused.

"Send Kiwi with a note. Like a carrier dog."

"I'll do that."

There was silence for a minute.

"Well, the factory's safe at least. Xana wouldn't fire at himself," said Odd.

"That give us time on Lyoko," said Jeremy. "But you'll need to hurry."

"It would be easier if you told us where the tower is!"

Kadic

"No more phones, no more school! No more phones, no more school! No more phones, no more school! No more phones, no more school!" chanted the students.

"I demand that you stop this strike now!" ordered Delmas.

Kiwi walked up to Yumi and sat down.

"Kiwi?"

"Yumi! What is going on? And why is this dog here?"

"He's not mine. It's a friend's dog from out of school and he came to see me."

"This is inadmissible," Delmas said, picking Kiwi up by the collar. "To my office. Now!"

"Did you see that?" asked Sissi. "We have to free her from the dictator. Free Yumi. Free Yumi!"

The other students started the chant too.

Delmas's office

"Yumi, I don't understand what's going on. A strike. A dog. You're usually much more sensible."

Yumi was ignoring him in favour of pulling the note out of Kiwi's collar and reading it.

"Yumi! Will you listen to me?!"

"I'm sorry but I have to leave. You too. In fact, everyone needs to leave!"

She exited the office along with Kiwi. Delmas sighed.

Lyoko

"According to the map, the tower is just across the bridge. Be careful though. It's guarded by…"

"Freaky hornets. We noticed."

"Remember, their poison will eat at your life points… oh. Harry's already dealt with them."

Harry had fired five shuriken in the time Jeremy had spoken.

"Homing shuriken are the best! Along with laser arrows. I wonder if it's possible to make homing laser arrows…"

"This isn't the time for experimenting!"

"Harry, why don't you use a sword or a Tessen fan?" asked Ulrich.

"I don't see much point. The fan takes too long to come back and with a sword, I have to get in close which increases the chance of getting hit. Oh great. Here come the Krabes."

One hundred Krabes had appeared.

"I guess Xana really loves sending Krabes against me," said Harry. "Aelita, you stay back. Let us deal with this."

They ran towards the army. Odd and Ulrich quickly got devirtualised due to the insane amount of laser fire. Once Harry was in the fight however, they didn't stand a chance. It still took a few minutes though due to Xana sending even more Krabes as Harry destroyed them.

"Hey, can you reload my weapons for me? I have this feeling that the ammo is running low."

"Ok. I can do that. Now you can go ahead," said Jeremy. "Oh no. Xana's taken over the satellite! Yumi!"

Kadic

"He let you go?!" asked Sissi in disbelief as Yumi ran up, panting.

"I escaped when I wasn't looking. Our demands are more important than anything. In fact, I think we should get all the schools involved with this. We can also protest in town."

Sissi looked at her minions.

"Everyone, into town. Let's get the other schools onto this!"

"Ok. Let's go! Freedom for all the schools! No more phones, no more school!"

"Yesss!"

"No more phones, no more school! No more phones, no more school!"

"You will not leave the grounds!"

Lab

"Wow. What a piece of technology!"

The reticule settled on France and started to zoom in.

"Parameters locked in place. Target localised," said the computerised voice.

"We were right. The laser is locked onto school!"

The screen showed several spots, representing people.

"I wonder how accurate this satellite really is. Oh no. Yumi! It's firing just at her! Really accurate though. Odd, go help Yumi and Ulrich."

Lyoko

"Are you sure the tower's here?" asked Harry. "Because I don't see it."

They were standing on a ice structure with no tower in sight.

"It's going to be around there. The map is always right."

"It could be buggy! Oh great. Bloks!"

Two blocks had appeared. Harry quickly got rid of them.

"You know, Xana still hasn't got the idea that he need to send more monsters after me," he commented. "I mean, my powers make me really powerful and really hard to hit so he should be investing some of his time into ways to stop me."

"Don't give him ideas. Ulrich and Odd have gone back to school to help Yumi by the way."

"That figures. Ulrich would do anything for Yumi. And Odd would do anything to help Ulrich. Have they gone on any dates yet?"

"This is not the time for discussing their love lives Harry!"

Harry looked at the waterfall thoughtfully.

"I'm going to check something."

He jumped down to the base and went behind the waterfall where the tower glowed an ominous red.

"Well, I found the tower. Aelita, do you want to deactivate it or should I?"

"You're already there Harry. It's quicker for you to do it since you're already there."

Harry quickly got up to the platform and placed his hand on the holographic screen.

"Whoever created this place was fond of holograms," he muttered.

Lyoko

The files zoomed down the tower, causing everything to go dark before a bright light rushed up.

Kadic

"You're making a terrible mistake Sir! We need to get out of here!" cried Yumi.

"I have had enough of this now, Yumi! I'm suspending you for a month! You can take your dog and leave this campus immediately! As for the rest of you, go back to your classrooms, this strike is now over!" ordered Delmas.

"Sir! It's a question of life and death! Let us all leave, please! I'd tell you the threat but you won't believe me."

"Hey, aren't you being a little dramatic, Yumi?" asked Sissi.

"I'm not being dramatic! Oh, hey Odd. And Ulrich too. Aren't you two supposed to be on Lyoko?" asked Yumi.

"We got devirtualised," panted Odd as he doubled over. "We need to go. Xana's taken control of a laser and he's going to shoot at the school."

"Xana? Lyoko? I demand that you tell me what you're talking about!"

"We need to go," Yumi said as the three ran off and a few seconds later, a laser fired.

The students gasped and quickly worked out why Yumi was trying to get them of the campus. She didn't want them to get hurt.

Yumi

The laser shot behind them.

"It's getting closer," said Ulrich.

"Thank you Captain Obvious."

The laser appeared again and froze ten metres away from them.

"Well, let's hope we go back in time," said Odd, looking at the laser. "Delmas will want to know what has been going on and that involves revealing more about Lyoko. Oh. Here it comes."

Lab

"Return to the past now!"

The white light covered everything.

Earlier

"What is this? Invitations to a party?" asked Sissi as she saw the notice the gang was putting up.

"Um…not really."

"What is this thing? "Official school policy reminder to all students. All mobile phones not turned off before entering the classroom will be immediately confiscated"?! Huh! That's incredible! Talk about teacher's pets! Anyway, I'd like to see someone try and confiscate my mobile!"

"You're so brave," said Herb.

"I wouldn't be so sure about that Sissi," said Harry. "You never know what could happen. All the phones could go off at once and get confiscated."

"You're such a dreamer!" Sissi entered the classroom.

"That actually happened, you don't remember it," Harry muttered. "I just hope that my instincts don't get any better though. They're already better than most and unlike the rest of my powers, I can't deactivate them. On the other hand, if Xana tries to grab me, I'll be able to react."

"Hey, it will be ok," said Odd. "You can always think of a cover story."

They entered the class for road nd

Harry's and Jeremy's Dorm

Harry was typing away on his laptop.

"How's it going?" asked Jeremy.

"Frustratingly slow. The materialisation program is a complex program and we're just two students. That means we have to deal with school and homework. Oh, I believe Ulrich and Yumi are going out tonight to see a movie."

"Oh, really? That's taken them awhile," said Jeremy.

"I know. It shows that they're serious about their relationship. At least they don't have to keep the secret of Xana between them. Now, if only Odd was the same..."

"There's not much we can do about that."

"I know. We can still wish though. I just hope he won't tell any of his girlfriend's about Lyoko."
