Disclaimer: I don't own Code: Lyoko or .Hack/SIGN.
Lord Maximus: This has nothing to do with my other crossovers, but I will be using Xana's form from them. It is much easier than thinking of a new one.
Chapter 4
The Lyoko ate at the school cafeteria. Everything was pretty much normal now they had finally destroyed Xana. Of course they still had to deal with Sissy now and then. Jeremy and Aelita started researching the mysterious Franz Hopper.
Even though Xana was gone he left behind a mystery. A mystery that might contain the key to Aelita's visions and the origin of Lyoko. Sissy walked by and smiled at Ulrich.
"Well, Ulrich when are you going to come to me and leave these losers behind?" asked Sissy,
"As soon as you admit you like Herb." said Ulrich.
"Don't bother, Ulrich. Not even Jim is in her league." said Odd.
Sissy growled and walked away, followed by her cronies.
"So, how's the research going?" asked Yumi,
"It is very complicated. We might need to check the data in Sector 5." said Jeremy.
"Why?" asked Ulrich,
"Because if anyone would know about Franz Hopper its Xana. Even though he is gone Sector 5 still holds all of his data. He wanted Aelita's memories and it had something to do with Franz Hopper." said Jeremy.
"It is easier said than done. Even though Xana's monsters are gone we still have the timer to worry about." said Ulrich,
"Relax, with me we can blast our way through the maze." said Odd.
"That sounds worse than Xana taking over the world." said Yumi.
They all laughed.
Deep in the depths of Lyoko a new being emerged in the form of a purple cloud similar to the black cloud Xana used. It entered Sector 5 and soon enough, made itself at home. It tried to access Xana's data, but it seemed he left behind hundreds of encryptions and a not even she could hack it. She cursed in her mind.
Even death he kept his secrets hidden. No matter, she could not access Xana's monsters, but that doesn't mean she could not create her own. Tsukasa and his friends arrived in Lyoko, but with her new powers the threat will be removed. However she needed the AI known as Aelita to understand Lyoko and to find out why Xana wanted her.
She knew he could not harm Aelita because his original programming was still encoded in him, which is why he sent the Scyphozoa to steal her memories so he could use her codes to free himself of his original programming once and for all. When Xana was born his original programming still existed so he could not kill Aelita or Franz Hopper. She was curious about Franz Hopper who was a friend of her creator, Harold. She now needs Lyoko to capture Aura and then trigger the birth of Dark Aura.
She began to create monsters of her own. Skeith was the leader of her army and now to see of she could use the towers. She created her own version of Xana's guardian and then programmed her Phases to drain Aelita of her memories. Even though she believes she knows why Xana wanted her, Morganna believes there was more to her than meets the eye.
Tsukasa and his friends walked around the Desert Region of Lyoko.
"Where are we?" asked Mimiru,
"I think I know. It is a virtual dimension similar to the World, but our bodies come here in data form and change into a human form so we can walk here. It is known as Lyoko." said Bear.
"How come we never heard of this place?" asked Ginkan,
"There are many things in the World we have yet to understand. This might be another mystery. However we can't think about that. Now that Aura is here Morganna will not rest until she is captured." said Krim.
Aura stayed close to Tsukasa as they walked through the desert. Deep in Carthage Morganna watched them. It was time. The Lyoko gang entered the factory and headed for the elevator.
Dark figures virtualized into Lyoko. They looked like muscular humans covered in black armor carrying large black swords. Yellow eyes could be seen in the helmets. They growled as they looked up.
"You all know what must be done. Bring me Aura and let nothing stand in your way." said Morganna's voice.
They Lyoko gang entered the computer room as Jeremy sat on the chair. He noticed new virtual cards of people and monsters.
"Wait guys. Take a look at this." said Jeremy.
They came and saw the cards.
"What are those?" asked Odd,
"New characters and new monsters." said Jeremy.
"But that is impossible. Xana is dead and no one besides knows about Lyoko." said Aelita,
"We better find out what is going on." said Jeremy.
Ulrich, Odd, and Yumi entered the scanner room and Jeremy started up the sequence.
"Transfer Ulrich."
"Transfer Yumi."
"Transfer Odd."
"Scanner Ulrich."
"Scanner Yumi."
"Scanner Odd."
"Virtualization."
They all vanished into Lyoko. Tsuaksa and the others noticed creatures heading for them.
"You want to fight? Come and get it!" shouted Mimiru.
She grabbed her sword and charged at them. The creatures tried to attack, but Mimiru swung her sword and sliced one of them in half. The Lyoko gang watched as the players attacked the monsters.
"Looks like we have trouble." said Ulrich,
"The creatures shone sign of Xana's codes. He is not the one controlling them." said Jeremy.
'We better help those guys." said Yumi,
"Can we trust them?" asked Ulrich.
"We know that they are fighting the monsters." said Odd.
They jumped out of their hiding spot and helped the players. Each group knew not who they were but they helped each other. Krim swung his spear and slashed through a monster attacking Ulrich. Odd fired arrows as a creature advanced on Subaru and Aura.
Yumi threw her fans at one creature and turned to see another behind her. It tried to strike her, but Bear stabbed it and it vanished into a flash of light composed of data streams. Yumi nodded and threw her fans at tow creatures charging at them. Soon enough the creatures were destroyed and they turned to each other.
"Thanks for helping us out." said Krim,
"No problem, but who are you and how did you get here?" asked Yumi.
"You ever heard of an online game called the World?" asked Bear,
"I have." said Jeremy.
The players looked around to see where that voice came from.
"That was Jeremy. He is talking to us from the real world." said Ulrich,
"We came here by accident when a powerful AI named Morganna attacked." said Krim.
"What was she after?" asked Aelita.
Krim pointed to Aura.
"This is Aura. The daughter of the creator of the World. Morganna was supposed to awaken her, but realized that she would be useless after Aura awoke and went rogue." said Krim,
"So we are dealing with another evil artificial intelligence?" asked Ulrich, groaning.
"Another evil artificial intelligence?" repeated Subaru,
"There was a powerful virus named Xana who used Lyoko to attack the real world, but we stopped him." said Jeremy.
"Morganna must have somehow discovered Lyoko and moved in. When did you guys defeat Xana?" asked Bear,
"About two day's ago." said Yumi.
"The same time Morganna stole a gate way so she could upload herself to another computer." said Ginkan,
"Great, just when we finally get rid of Xana another evil shows up." said Ulrich.
"Morganna must have found out you destroyed Xana and moved in." said Bear,
"How could she have known?" asked Aelita.
"What do you mean?" asked Tsukasa,
"Nobody knows about Lyoko or Xana besides us." said Yumi.
"There is a rumor in the World that Lyoko was part of it, but was deleted." said Krim,
"So Aelita might have come from the World?" asked Odd.
"That is unlikely. The sprite known as Aelita was the creation of a man named Franz Hopper and the father of a girl named Aelita as well." said Ginkan,
"What do you know about Franz Hopper?" asked Aelita, quickly.
"Only that he was friends with the creator of the World." said Ginkan,
"We have Franz Hopper's diary saved on our files but they are heavily encrypted." said Jeremy.
"I know someone who can help." said Bear, smiling.
In Carthage Morganna seethed with anger. Now she had more obstacles in her way and would not stand for it. It was time to use the towers. In the Desert Region a tower glowed purple.
The factory started up and a purple fog came out and entered a car in the junkyard out back. It came to life and headed for the factory. Jeremy looked at the computer and tower was activated.
"Sorry to interupt, but it looks like Morganna has learned how to activate the towers." said Jeremy.
Inside Lyoko the warriors gasped. The players were confused.
"What does that mean?" asked Mimiru,
"It means Morganna has found a way to escape Lyoko and took control of something in the real world. The only way to stop her is to deactivate the tower." said Aelita.
They nodded and Jeremy programmed the vehicles. Subaru and Aura stayed behind as the others took of. They soon saw the tower and saw a large figure guarding it. It was Skeith.
"What is that thing?" asked Ulrich,
"Something that you wish you never met." said a voice.
A tall boy with green hair jumped and attacked Skeith.
"Sora!" shouted Tsukasa.
Sora jumped as Skeith swung his staff. Soon enough an army of armored creatures appeared and attacked. Odd fired his arrows, but it took about five to destroy one. Krim jumped and slashed the creatures and moved as Skeith attacked. Aelita ran past them and entered the tower.
A group of creatures surrounded Subaru and Aura and grabbed Aura. A black orb appeared and Aura vanished into it.
"Aura!" shouted Subaru.
The car rammed into the elevator and shook the factory. Aelita traveled to the upper platform and placed her hand on the screen.
AELITA
CODE LYOKO
The tower now glowed blue and the creatures vanished. The car stopped and Morganna was contained in Lyoko. Subaru ran to them.
Tsuaksa, Morganna's creatures took Aura!" said Subaru,
"What?" asked Tsukasa.
"It's okay. Morganna needs Aura alive for now." said Krim,
"We can materialize you guys so you wan'y be trapped here." said Jeremy.
They nodded and thanked them.
