A Piece of Lyoko

"Alright, boys," bellowed Jim. "Time for your monthly inspection." He marched down the hallway taking account of each male student present for their dorm inspections. He walked past Odd and Ulrich, who were standing in front of their dorm room. Jim lifted an eyebrow. "Hey, have you two seen Jeremy Belpois?" Jim looked beyond them. "He's not standing in front of his room."

Ulrich opened his mouth. "Uhh…Jeremy's using the restroom right now. He'll be back soon."

"Well if he's not here by the time I'm though with all of you I'll have to find him myself." Jim continued marching.

Abruptly, Ulrich leaned over and whispered into Odd's ear. "Hey, where's Jeremy?"

"Einstein's at the factory working on something," Odd said.

"Well, he'd better hurry up."

(-o-)

"Shepherd's pie?" said Odd loudly. "It's gross enough to make my physically sick." He sat down on the lunch bench across from Aelita.

"Actually, I like shepherd's pie. I think it's one of my favorite entrées." She put a forkful into her mouth. "I used to love it when I was little."

Ulrich sat down next to Jeremy. "Hey, Einstein, where were you? You missed the inspection."

"Sorry," he said, finishing up his lunch. "I was just finishing up something at the lab…"

Just then the four heard a loud voice from behind them.

"There you are, Belpois!" said Jim.

"Jim!" Jeremy turned around.

"Done with your food? Then come with me." He grabbed Jeremy by the arm and dragged him out of the cafeteria.

(-o-)

"What is this?" bellowed Jim. He looked around at the mess that Jeremy called his workspace. CD cases and dirty laundry were lying around everywhere. "You are not to leave this room until it is spick and span! You hear?"

"Jeremy!" Aelita called from the hallway. She and the other two boys had finished their lunch and followed him.

"What are you three doing here?" asked Jim severely.

"We thought Jeremy could use a little help," mentioned Ulrich.

Jim got even madder. "Jeremy is going to clean his room by himself! Now go to your classes on the double!" Suddenly, Jeremy's computer started to beep loudly. "What's going on?" demanded Jim. "And what are you three still doing here? Scram!" He shut the door, leaving Jeremy to deal with his computer.

"You think it's an activated tower?" Ulrich asked.

"One way to find out," said Aelita, leading them out of the dormitory wing.

(-o-)

The three decided to take the path through the woods. When they reached the manhole, they saw two Tangela emerge from a bush.

"Those Tangela don't look very nice," commented Odd. The Tangela raised their vines and shot them out at the group.

"Nuzleaf! Come out!" Ulrich threw his Pokeball in front of him. "You two head for the factory!" he ordered. Odd and Aelita climbed down the manhole, leaving Ulrich and Nuzleaf to battle the XANA-fied Tangela.

(-o-)

William leaned against the school gate impatiently. "Mr. Chardin," he called, "The bus is late. Do you think we'll still be able to go on that field trip to the art museum?"

"Yeu crack me up, Monsieur Dunbar," said the professor. "We aer going to walk." William let out a groan and trailed behind his class behind Yumi. "Az studen of ze visual art, you must do anything for art. Right, clazz?

The students let out a large groan.

Mr. Chardin took in a deep breath. "Ahh…notzing like taking in zome fresh air right before taking in zome fine art. Oui, Queulorior?"

"Smear," said the Smeargle, happily strolling next to the teacher.

Yumi had just received a call on her cell phone. Luckily no one heard it because she was trailing behind her classmates. "Jeremy? What are you up to?"

Jeremy was jogging across the plaza. "Well, I've finally managed to clean my room, but I think XANA is on the attack. I'll meet you at the factory."

"Which part of the art museum are you going to see first?" asked Christopher to William.

"The gift shop," chuckled the black-haired boy. "I'm going to buy something for Yumi. What would you like me to buy for you, Yumi?" He turned around, but no one was there. "She always picks the right time to bale on me," he said to himself.

(-o-)

"Kiwi!" The Granbull jumped into Odd's arms and licked him as the elevator door opened.

"What's your Granbull doing here?" asked Aelita.

Odd looked at her. "Remember? I had the dorm inspection today. I didn't want Jim to see a dirty mutt in my room."

"Okay, well I'll start the self-virtualization process." She hopped over to the computer chair and entered the sequence. Then, she followed Odd and Kiwi down the elevator.

"See you in a bit," she said and stepped into the scanner, making sure that Skitty's Pokeball was in her pocket. The doors closed on them, and before they knew it, the four of them were virtualized into the Forest Region.

"Over there." Odd pointed. He could see the tower, but there were four Tarantaraks in the middle of the pathway.

"Watch out, Odd!" yelled Aelita. A Signal Beam had been shot in Kiwi's direction.

"Protect!" Odd ran in front of Kiwi and crossed his paws, activated the purple shield. "Kiwi! Scary Face!" The Granbull galloped around Odd and used its attack to lower the speed of one of the Tarantaraks. "Laser Arrow!" He fired the shot and the sluggish monster and devirtualized it. He looked over at Aelita. "Well, aren't you going to help me make a clear path to the tower?"

"Right." She shook away her nervous thoughts and summoned another one of her glowing orbs. She fired it towards the monsters, but it missed.

"You need practice," Odd noticed.

Aelita seemed disappointed with herself, so Skitty leapt ahead of her and Sang to one of the monsters.

"Good job, Skitty," said Odd sweetly. "You could really learn a thing or two from Pukka."

"Hey, only I can call her that!" Aelita rebuked.

"Whoa, sorry," Odd said. He and Granbull led Aelita and Skitty past the sleeping Tarantarak, but the other two monsters followed. The two fighters and their Pokemon hid behind a giant tree.

"What are we going to do?" asked Aelita.

"Kiwi and I will distract them, while you and Skitty run for the tower." Aelita wanted to say something, but Kiwi and Odd had already left the hiding spot. Odd leapt up and bounced off the head of one of the monsters. Kiwi ran up to it and used Tail Whip, causing a blue light to shine down on it. Odd used his claws to ascend up a virtual tree. He did a back flip, leaping off the tree in the process. On his way back down to the ground, Odd fired two Laser Arrows at the weakened Tarantarak.

Aelita didn't want to head to the tower just yet. There was still one monster that was awake. The Tarantarak fired multiple lasers at the dog, but it quickly dodged all of them. It Headbutted the monster's stomach, and Odd fired two more Laser Arrows at that monster's eye.

"Odd!" called Aelita. "The Tarantarak has woken up!" Odd turned and saw the last monster chasing after him. He ran onto a pathway, getting farther away from Aelita with every step. Now that the coast was clear, Aelita and Skitty made a dash for the tower.

(-o-)

Jeremy arrived in the center of the woods, where he viewed a shocking scene. Ulrich and Nuzleaf were on the ground, Wrapped by two Tangela. "Jeremy," Ulrich grunted, "get rid of the Tangela!" Jeremy sent out his best companion, Metang.

"Metangg!" it screeched after emerging from the Pokeball, but just then, a vine-like whip shot out from behind a tree and struck the Steel-type Pokemon. The botanic monster rose from behind the tree and shuffled into view. It was covered in shaggy, blue vines from head to toe. A few of the vines were acting like arms. This was a Pokemon that Ulrich had never seen.

"What in the world is that?" he screamed.

"Don't you pay attention in class?" asked Jeremy. "It's a Tangrowth. The evolved form of Tangela. Metang, use Metal Claw!" The Pokemon brought its right arm back and charged towards the 6-foot-tall monster. The Tangrowth's eyes flashed red, and it swung its long, thick arm at the Metang, knocking it straight into the ground.

"What the?" Jeremy was being entangled by more vines. Two more Tangela had appeared and were Wrapping Jeremy and his Pokemon.

"Nuzleaf! Nature Power!" Ulrich hoped to paralyze the Tangela, but Stun Spore had no effect on the Grass-type Pokemon. "All we can do is wait for Yumi," he said.

(-o-)

"Oh no." Aelita and Skitty stopped in their tracks. They hoped that they would never see this monster again, but there it was, right in front of them. "Pukka, go and hide," but the Skitty had already ran behind a grassy rock and curled up into a ball. Aelita threw two balls of energy at the monster, but both attacks missed. The Tentazoa's tentacles shot out at Aelita and had Wrapped Aelita for good.

Odd and Kiwi had reached the end of the pathway and were now cornered by the Tarantarak.

"Aelita?" Odd saw Aelita being captured by the Tentazoa. "Sorry, Ugly, but Kiwi and I got to run!" He and Kiwi ran around either side of the monster, while the Tarantarak just stared. It fired a continuous array of lasers and the fleeing warriors. "Skitty!" He ran over to it and woke it up. "Aelita!" from where Odd was standing, he fired three Laser Arrows at the Tentazoa, making it flee. He and Kiwi ran over to her to make sure she was okay.

Aelita got up looked right into Odd's eyes. Odd gasped. The mark of XANA was evident in Aelita's stare. With a zombie-like grunt, Aelita delivered a sidekick to Odd, knocking him into a tree. Kiwi leapt up and tried to bite her, but she devirtualized it with her green blast of energy. The last Tarantarak had caught up to them, but it noticed that XANA had taken over the girl. It knelt down, letting Aelita climb up onto its nose. Skitty looked up and saw her owner being taken to the tower by the Tarantarak.

(-o-)

"Help!" called out Jeremy and Ulrich. "Help!" Fortunately, Yumi had heard their cries.

"I'm here, you guys…Whoa! What happened?" She looked around at the viney mess. Dozens of Tangela had turned the woods into a jungle, and it seemed that they were being controlled by the XANA-fied Tangrowth.

"Yumi!" called Jeremy from the cluster of vines. "You have to get rid of that Tangrowth!" He and the others were helpless and motionless.

Yumi took out her Pokeball. "Misdreavus!" She tried to think of a way to avoid being trapped in the tangled mess. "Astonish!" The dark Pokemon floated up to the Tangrowth and tackled it. "Yes!" thought Yumi. Just as she hoped, the enemy Pokemon had flinched. "Now Psyw…" Three Tangela had crept up on her and had wrapped her limbs and her mouth. Two more tried launching their vines at Misdreavus, but they had failed.

"Bind is a Normal-type move," announced Jeremy. "They have no effect on Ghost-type Pokemon."

"Misdreavus!" shouted Ulrich. "Go ahead and use Psywave!"

"Misdrea Vus!" It released its beams at the Tangrowth's body and damaged it a little.

"Watch out, Misdreavus!" called Jeremy. "It's using Power Whip!" A shocked Misdreavus got pummeled into a tree trunk by the Tangrowth's huge arm. "It's a female," said Jeremy, noticing its red fingers. "No wonder it's got such a temper."

(-o-)

On Lyoko, the monster was on its way to deliver Aelita to the tower.

"Laser Arrow!" screamed Odd. He shot four arrows at the monster, but one of them hit Aelita. She fell off the monster and continued to run towards the tower. "What has gotten into her?!"

Aelita entered the tower and floated up to the second platform. The tower recognized the being as Aelita, but what happened next was unthinkable. Aelita entered the code XANA in the Forest Sector's tower. Odd looked up as the red tower started to disappear. "Aelita!" The pink and green girl fell to the ground.

"What…what happened?" she asked Odd, getting up. "Where are all the monsters?" But somehow, the Tarantarak had made its way to a pathway farther away from the tower.

"Look!" Odd pointed at the spot that the monster was standing on. The ground had lost its color and had turned into a wire frame. The Tarantarak had fallen into the digital sea, disappearing in a column of light.

"The sector's disappearing!" yelled Aelita. She ran away from the disappearing pathways with Odd and Skitty. "What are we going to do?"

Odd fired Laser Arrows at the disappearing path while still running. Nothing happened. "We have to get back to the factory!" he said. He stopped running and spoke faster. "On three you're going to shoot me with those energy thingies. One…" He loaded his wrist and pointed it at Aelita. "Two…" Aelita charged up her spheres hesitantly. "Three!" In an instant, the three of them were gone.

(-o-)

"Yumi" yelled Ulrich. He knew for sure that the vines were now choking her, holding her breath. If he didn't do something, everyone was going to choke to death. Ulrich squirmed like a Magikarp, trying to break free of the Tangela's vines, but it was useless. He looked over at the knocked out Misdreavus and the large Tangrowth. "Hm?" It looks like Aelita had deactivated the tower already. The Tangrowth's eyes returned to normal, and it eased up on its vines. All Ulrich had to do was wait for the return to the past.

(-o-)

Odd calmly emerged from the scanner in the scanner room. "Aelita?" he looked around, but neither of the two scanners was opening. "Oh no, what have I done?" Thankfully, the scanner on his left had opened. Skitty leapt out of the milky smoke. "Skitty! Where's Aelita?" Then, the scanner on his right opened up. A tired Aelita was lying on the floor. Odd ran over to her and helped her up.

"What's that in your hand?" asked Odd. Aelita held up a lime green rock that was a little smaller than her palm. "That's all that's left of the Forest Region, huh?" he said. "Hurry, Aelita, who knows what danger our friends are in?"

"Right," said Aelita. She quickly went up the elevator and started the sequence on the supercomputer.

Return to the past, now…

"So you finally cleaned the place up, huh, Jeremy?" said Yumi, looking around the room. The time reversion had brought them to Jeremy's room the night before the inspection.

"Yeah," he said, sitting in his chair. "All thanks to XANA's attack and Aelita launching the return to the past."

"Thanks," uttered Aelita.

"Thanks for deactivating the tower, too," said Ulrich. Aelita gave a nervous chuckle.

"About that…" Odd started up. "How should I put this?" Odd scratched his head.

"I destroyed the activated tower," spoke up Aelita.

"How did you do that?" asked Jeremy, interested.

"I destroyed the entire Forest Region," continued Aelita.

"What?" screamed everybody simultaneously.

"Yeah," said Odd, "The Tentazoa took control of Aelita, forcing her to enter a tower and destroy the entire sector."

Aelita gave the green rock to Jeremy to examine. "XANA must be trying to destroy all of the sectors," he said, "in order to prevent us from reaching Sector Five and stopping him from destroying the core." He gave the rock back to Aelita.

"Looks like got a new challenge on our hands," said Yumi.

"Yeah, to try to stop Lyoko from falling to pieces," said Odd. Everyone laughed at his pun-ny joke.
