Code LYOKO - Battle of Wakusei

Chapter 1

Code: WAKUSEI

One year ago, they saved the world. One year ago, they stopped an evil menace. They emerged victorious after the Battle of Lyoko, the parallel universe built within the supercomputer hidden beneath the abandoned Renault Factory. They destroyed XANA and saved the world from domination by the virtual being. That was one year ago. Now the Lyoko Warriors have taken their separate ways; Aelita and Jeremie are working together on their robot and program prototypes, Odd is spending his time studying for his next lessons, and Ulrich and Yumi practice martial arts together, while William moved out of France to live in America. They were so caught up in what they were doing that they didn't notice that what was going to happen was going to take them into another fantastic and terrifying journey.

During the construction of their machines, Jeremie and Aelita found that they were lacking a few parts needed to input their primary programming. "Jeremie, do you think that this is enough space for the robots programming?" asked Aelita, referring to the three memory hard discs they had mounted to the machines.

"I don't think so," said Jeremie, "Those discs can hold plenty of data, yes, but it's not enough space to store their programming. If we're going to get these things finished, we'll probably need a couple more hard discs or data cores."

"I think I might know where to get some," said Aelita, "There's an old warehouse near here, which used to be a software company storage facility until it was condemned in the 70's."

"We should probably get the others to help us then," said Jeremie, "You never know what we'll find there."

"Well, no sense in worrying about finding another virtual world," said Aelita, "After all, there's only one Lyoko."

Jeremie laughed and agreed before he called the others and they all headed to the old APEX Corporation Warehouse. The warehouse itself wasn't that far from Kadic Academy, in fact it was closer than the factory. They met at the warehouse entrance around ten minutes after Jeremie called.

"Alright," said Jeremie, "We're looking for hard discs or data cores. Any kind will do."

"This feels really weird," said Ulrich, "It's like we're going back to Lyoko."

"It feels the same way for all of us, Ulrich," said Aelita, "There's nothing to worry about."

Jeremie opened the door and they all walked inside. The warehouse interior looked like it hadn't been used in over eighty years, despite it being only about 50 years old. The previous owners must have left everything piled up when the warehouse folded up. Jeremie and Aelita checked out the main offices, while Ulrich and Yumi looked around the second floor, and Odd decided to search the first floor himself.

After about 15 minutes of looking, Odd yelled out, "Hey! I found something!"

Everyone gathered and asked, "What is it, Odd?"

Odd was looking inside a cabinet in one of the desks at the corner of the room. Jeremie expected it to have at least a shelf inside, but instead it opened onto a hidden tunnel. "What is this?" asked Yumi.

"It looks like an entrance to a mine," said Odd, "Should we check it out?"

"Only one way to find out what's back there," said Jeremie as he crawled in. The others followed him into the tunnel which got wider to the point in which they could stand up. After a few feet, the tunnel ended at what looked like an elevator to a military bomb shelter. They turned the lever to descend, and when they reached the bottom, opened a large steel door which led into a large underground computer lab, much more complex than that in the Renault Factory.

"What's all this?" asked Ulrich.

"It looks like another supercomputer lab," said Jeremie, "Let's see what we can come up with."

Jeremie headed over to the mainframe and switched on the main monitor. As soon as it turned on, eight other monitors turned on revealing maps of a virtual world.

"I guess I was wrong," said Aelita, "It looks like we have stumbled upon another virtual world."

"It's called Wakusei to be exact," said a voice from the computer. Everyone jumped in surprise and watched as a video communication window opened on the main monitor revealing a boy around the age of 17 who was wearing high tech armor. "Allow me to introduce myself," said the boy, "My name is Ulysses Hindman. I created this virtual world."

Jeremie sat at the monitor. "Hello, Ulysses," he said, "I'm Jeremie Belpois, and these are my friends, Aelita Schaeffer, Odd Della Robbia, Ulrich Stern, and Yumi Ishiyama."

"It's nice to meet you all," said Ulysses, "I'm glad you found me."

"Why is that?" asked Jeremie, "Are you trapped in there?"

"Yes," said Ulysses, "Currently, I'm a digital incarnation of my mind. My physical body is in the next room on one of the synchronizers."

Odd opened the door to the right of the computer interface. The room inside was filled with what looked like beds with spinal and neural scanners. One of them had Ulysses' body on it and a holographic screen was over his closed eyes. "How did you get trapped?" asked Odd.

"I was abandoned during my first test of Wakusei's sync program," said Ulysses. Everyone gasped. They had not expected him to be abandoned. "Yes, some morons I trusted left me in here to rot," he said, "I've been stuck in here for three years. Do you think you could get me out?"

"Maybe," said Jeremie, "Can you walk me through it?"

Ulysses explained to Jeremie the whole purpose and concept of the synchronizers and told him the codes needed to sync and desync people in and out of Wakusei. Jeremie tried to desync Ulysses, but the program didn't respond.

"Damn," said Ulysses as Jeremie told him what had happened, "It appears that due to me being in Wakusei for more than a year, I can't be ejected until the Code: EARTH program is activated in one of the obelisks."

"Obelisks?" said Aelita.

"Yes," said Ulysses, "The obelisks are gates between Wakusei and the real world, gates to other sectors, and also power sources for programs created in the computer. If the failsafe Code: EARTH program is activated in an obelisk while I'm inside, I think that will bypass the problem with the desync code on my signal."

"How can we get you to an obelisk?" asked Ulrich.

"Well, Jeremie will have to synchronize the four of you into Wakusei to help me out," said Ulysses, "I'm pretty sure that HADES has activated an obelisk and we will need to shut it down. There's very little time to explain, so I'll explain when I get out of here."

"Alright, let's get moving," said Yumi.

Aelita, Odd, Ulrich, and Yumi lied down on the synchronizers as Jeremie prepared them. "Transfer!" said Jeremie as he typed in the code. Holograms appeared over their faces. "Scan!" said Jeremie and the holograms scanned their heads. "Synchronization!" said Jeremie as he implemented the final code. The Lyoko Warriors felt as though they had passed through a warm shower as they became surrounded by white digital cubes and flying files. The digital void had been switched with flying mountains, similar to those of Lyoko, and their clothes had been switched with elaborate outfits; Aelita was in a pink dress with metal plating, Odd was given purple armor and laser wristbands, Ulrich was completely dressed in metal plated samurai armor and was given a long-sword katana, and Yumi was given a black and red digital armor and bladed throwing disks as weapons.

"This is interesting," said Aelita.

"No time for sightseeing guys," said Jeremie, "Ulysses needs our help."

"That's right," said Ulrich, "Where is he, Jeremie?"

"A little ways north of where you are now, at the edge of the sector," said Jeremie.

They didn't waste a second and started running north to find Ulysses. After they had gone about 50 meters north, they had come an area of the sector that appeared to become more pixellated and turn into the digital void the further they went. The path and the sector itself ended at what appeared to be a giant wall of white cubes. Ulysses was there, sitting on the near invisible floor. He immediately got up and said, "Thanks for coming to help me out."

"No problem," said Ulrich, "And nice job on the virtual world."

Jeremie called out to them, "Guys, no time for small talk! I've detected an activated obelisk within your vicinity!"

"As I thought," growled Ulysses; he did not like having to deal with this, "Well, let's get this over with. Where's the obelisk, Jeremie?"

"The obelisk is on the neighboring plateau, south by southeast of you," said Jeremie.

Odd looked at the plateau, which was several yards away. "How are we supposed to get over there?" he asked.

"Each of you was given a special power which corresponds to your memories and personality," said Ulysses, "Use them and follow me." Ulysses then jumped off the cliff edge, but instead of falling into the ravine, he seemed to hover to the other plateau. "Come on!" he yelled.

Remembering their powers on Lyoko, Aelita activated her wings, Odd jumped with cat-like reflexes, Ulrich used his super-sprint while jumping, and Yumi activated her telekinesis to hover. They reached the plateau within a few seconds.

"Good job," said Ulysses, "You learn fast. Now let's get to that damn obelisk so we can get out of here!"

They started running in the direction of the obelisk. When it came into view, they saw it had a blue aura around it. "Isn't that supposed to mean it's offline?" asked Aelita.

"No," said Ulysses, "If the obelisks have no aura whatsoever, they are offline. If it has a blue aura, it means HADES has launched an attack."

They continued running toward the obelisk and they were a few meters away when it was blocked by giant scorpion monsters. "Skorpiens!" yelled Ulysses in shock as the monsters fired huge laser blasts from their tails, "Incoming!" They had just barely dodged the lasers. "I hate these things!" he said, "Powerful lasers, 20 life points per hit. We'll need to cut off their tails to disengage their lasers and stab their heads! That's their weak spot!"

Ulrich nodded and signaled to Odd and Yumi their battle positions. Ulrich counted down 3, 2, 1 with his fingers, and they all charged for attack. Odd distracted the Skorpiens while Ulysses used his dual laser blade to slice their legs off, Yumi cut their tails off, and Ulrich and Aelita used their weapons to stab and destroy the heads of the Skorpiens. After they fell dead, the Skorpiens disappeared into digital lines and binary code. "That takes care of the Skorpiens," said Yumi, "But the obelisk isn't clear yet." She pointed to a masked figure standing at the base of the obelisk.

"The Calibos," muttered Ulysses, "HADES created it to guard the obelisks that have been activated, and it's one of the most dangerous monsters on Wakusei because it can imitate the abilities of those who attack it. I'll face it." Ulysses stepped forward and the Calibos drew its weapon and they began a furious fight. Ulysses used all of his fencing skills and even separated his dual laser blade into two single blades to block and attack at the same time. The Calibos made one successful strike at Ulysses side. He grunted in pain, but he managed to throw off the monster. The Calibos attempted to charge at Ulysses, but a sudden build up in telekinetic energy stopped it. The energy produced strong winds, freezing temperature, and roaring flames which surrounded Ulysses and compressed before exploding and throwing the Calibos into the wall of the obelisk.

As the monster disappeared, Yumi asked Ulysses, "What was that you just did?"

"I used the four forms of telekinesis," said Ulysses, "If one's mind is strong enough, they can manipulate the movement of atoms, giving them the abilities to create and manipulate fire, air movement, and freezing temperatures. Now let's get this obelisk out of commission."

They all walked up to the obelisk and they entered via a gravity lift to the pyramid at the top. The interior of the obelisk looked similar to the interior of a Lyoko tower except the code was red and the floor was a different symbol, like the head of a scepter. Ulysses stepped to the center ring of the floor and a screen appeared in front of him. He scanned his palm, it recognized him as Ulysses and asked him for the code. Ulysses used the keypad hologram and dragged the letters into the line to enter Code: WAKUSEI. "Obelisk shutdown," said Ulysses as the codes fell down the obelisk and reset on the walls.

"Good job, guys!" said Jeremie, "Alright, I'm starting the Code: EARTH program immediately." Jeremie located the Code: EARTH program and started it up. On Wakusei, the obelisk interior disintegrated into the digital void and everyone's outfits had switched back into their normal clothes. As soon as the holograms over the synchronizers disappeared, Odd and Ulysses fell off and doubled up on the floor moaning.

"I should have prepared for this," said Ulysses sounding as though he was going to vomit at any moment, "It's the symptoms of exiting Wakusei for the first time."

"And exactly how long does it last?" moaned Odd.

Ulysses started sounding lightly better as he said, "About a minute."

After the symptoms passed, Ulysses explained what HADES was and that it was originally programmed to govern Wakusei and it's creatures until it gained sentience and made the decision to destroy humanity. After the explanations were said, Ulysses then attempted to delete HADES and Wakusei, but the computer refused to respond.

"Damn it!" he exclaimed, "HADES has completely bugged my system. I can't shut off my computer or delete HADES or Wakusei."

"And you can't debug the system?" asked Aelita.

"No," said Ulysses, "The system data is shrouded by maximum encryption. I will need to develop a program to delete HADES once and for all when we shut down Wakusei."

"Well, it looks like we're in for another battle," said Ulrich.

"Yeah, but hopefully it won't last long," said Ulysses, "Hey wait, what do you mean another battle?"

Jeremie explained their previous battle on Lyoko with XANA and their troubles with Kadic Academy, the government, and facing their friends and people possessed by XANA. "I see," said Ulysses as Jeremie finished the story, "I'm sorry you guys got dragged into this."

"Ah, it's nothing," said Yumi, "We're actually quite used to this sort of thing."

"Okay," said Ulysses, "Well, thanks again for rescuing me. It's best that you head back to Kadic Academy, it's almost midnight."

"You're right, but where are you going to stay the night?" asked Odd.

"I don't really know," said Ulysses, "I'll probably have to stay the night here."

"You should really find somewhere comfortable to sleep," said Yumi, "If you want to, I can sneak you into my place and you can hide out there overnight."

"Sounds like a good idea," said Ulysses, "The only problem is I don't have any spare clothes."

"Don't worry," said Ulrich, "I have some that you can use."

"Thanks Ulrich," said Ulysses.

After leaving the warehouse, Yumi and Ulysses headed over to her place while Ulrich smuggled some of his spare clothes out of the school and Yumi took them to Ulysses. The rest of the night was rather quiet, except that Ulysses was experiencing nightmares of what had happened to him and his little brother three years ago.

Our heroes' new adventure begins with a new teammate, but an even deadlier enemy as well. And it seems Ulysses had a little brother before he was trapped in Wakusei, but whatever happened to him? Find out later on...
