I do not Code: Lyoko. The only things I own are Xana's design, the story, and the new antagonist.

Somewhere in Boulogne-Billancourt, France stands an abandoned factory. To most people, there was nothing special about this factory. However, to a group of six teenagers, there's something very special about it, or, rather, underneath it. For there, a short elevator ride away, was an incredible supercomputer, with a virtual world called Lyoko inside of it. The supercomputer had been shut off recently after the teens had once and for all defeated their nemesis, an evil A.I. named X.A.N.A. who wanted to take over the world and wipe out humanity. They had done so wanting to leave this part of their lives behind. However, they would soon learn that their troubles were not over yet.

That night, one of the scanners needed for virtualization hummed to life. It soon opened and a young girl was lying inside it. She had long black hair and was wearing a short-sleeved black shirt with a red Eye of X.A.N.A. on it that had a long-sleeved red shirt underneath. She was also wearing denim jeans and black sneakers with red laces. She moaned as she opened her red eyes. Now awake, she looked out of the scanner at the room.

"I'm in the Scanner Room," she observed, "It worked. I've successfully materialized myself."

They say appearances can be deceiving. That applied to this girl. Though she looked like a normal human, she wasn't. She was X.A.N.A., the A.I. that the teens thought to have been destroyed. As to how she survived, she simply created her own DNA signature some time before she was destroyed and materialized herself using a program that one of the teens, named Jeremie Belpois, had developed to materialize another teen, named Aelita Schaeffer. As to why she materialized herself, as a multi-agent program, she had evolved enough to tell right from wrong and decided to live in peace with Jeremie and his friends. They were unaware of this, though.

X.A.N.A. got up and walked to the elevator and went down to the Supercomputer Room, which was on the floor below. The Supercomputer was still off and X.A.N.A. was planning to turn it back on. She got out of the elevator and walked up to the switch. She flipped the switch and the Supercomputer rose out of the floor. The panel opened and the switch for the Supercomputer came out. X.A.N.A. flipped the switch and the Supercomputer turned on with a gust of wind blowing on X.A.N.A. With that done, she went back to the elevator and took it up the Computer Lab. Once there, she got out and sat down in the chair.

"Now, let's get started, shall we?" she said.

What she was doing was simple. She was forging her fake ID, so she could attend Kadic Academy, a boarding school in Sceaux, not too far from the factory. This is where the teens attend school. Given her physical age, X.A.N.A. put herself in the same grade as Yumi Ishiyama, the oldest of the group physically as Aelita didn't age while in Lyoko. With her phony ID completed, Xana Stones set about getting her money for tuition, school supplies, and personal things. She did this by taking small sums of money from a couple of banks across France. Small enough so nobody would notice. Once she was finished gathering money, she placed it all in a bank account she had just created for herself. She then paid for tuition and supplies. With that done, she was officially a new student at Kadic Academy. She would start in the morning.

With everything out of the way, she logged out and called it a night. She took the elevator back to the ground floor. She got out of the elevator and looked up at the moonlight coming through the factory windows. She found a recliner across the floor. This was the recliner Jim Morales was lying on after he got fired due to Jeremie hurting his ankle. Of course, there was a Time Reversion so, technically, Jim was never fired. Nevertheless, Xana walked over to it and laid on it. She closed her eyes and slept for the first time.
