The story starts with a computer opening up and shows a video about the history about Lyoko and a pink hair girl named Aelita.
Narrator: It is the most important fact that things are not as alway seem to be. But there is one fact about Code Lyoko that Aelita Hopper was the first human girl to go to Lyoko by herself. She was born to Waldo Schaeffer and Anthea Schaeffer about 22 years before the events of her adventures on Lyoko happened. She lived happily with both of them in the mountains and her parents gave her an small elf doll as a gift and her father taught her to play piano. One day however, her mother disappeared by the men in black who wanted to get Aelita and her father's work which Waldo was working on a project beyond our intelligence of technology called Lyoko.
The computer screen now shows scenes of Aelita's flashback.
Narrator: As Waldo Schaeffer moved with her to The Hermitage and changed his name to Franz Hopper, Aelita was home-schooled. She was unaware about her father's laboratory, supercomputer and X.A.N.A..
The computer now shows Aelita in her bedroom and saw the men in black outside through her window.
Narrator: One day, however, she had to hide Mr. Pück, who had a hidden key to Franz Hopper's locker in the local train station. When Aelita came back from biking, two men dressed in black arrived at The Hermitage, forcing Franz Hopper and Aelita to escape through the Sewer to the abandoned factory, where Aelita discovered her father's secret laboratory.
The computer now shows Aelita and Franz in the scanners and were virtualize to Lyoko.
Franz Hopper virtualized Aelita and himself in order to keep themselves safe and the next thing Aelita knew, she was in the Forest Sector of Lyoko. There, Kankrelats attacked her and her father, forcing them to hide in the nearby tower. Franz Hopper explained that he had to go and make peace with X.A.N.A., the artificial intelligence that wanted to destroy them both.
The computer now shows Aelita inside the forest sector's tower in her lyoko from.
Narrator: Aelita had to wait in the tower. However, she can't wait much longer and goes outside, where Hornets were attacking her father. Franz Hopper explained that X.A.N.A can't be stopped. After asking Aelita to promise that she'll never forget him, Franz turns off the supercomputer to prevent X.A.N.A. from attacking Earth, leaving Aelita inside it for 10 years.
The computer now shows a young boy in the supercomputer.
Narrator: 10 years later, a boy named Jeremie Belpois was looking for parts for his robots in an abandoned factory, he eventually finds the supercomputer and restarts it. Aelita awakes almost immediately afterwards, but didn't remember anything about her past. Jeremie assumed she was an Artificial Intelligence and decided to name her Maya, after she requested to be called something other than "Artificial Inteligence". But after fixing the issues of the mess Jeremie and his friends, Odd, Ulrich, and Yumi made, he found a program called Return to the Past and it works. Maya soon remembered that her name is Aelita and Jeremie will find a way to get Aelita out of Lyoko and into Earth.
The computer now shows Aelita out of Lyoko and into Earth.
Narrator: Few days later, Jeremie soon manages to create the correct materialization program, sending Aelita to the Forest Sector. However, monsters attack her and the tower she is in in order to stop her from leaving. But with the help of Ulrich, Aelita materializes for the first time on Earth with others being at the Scanner room to welcome her. Jeremie had her enrolled to Kadic as Odds' cousin and Yumi had her parents convinced about she staying at her home and Aelita was even better than Jeremie in the classes. But when team tried to shut down the supercomputer, Aelita collapses. As Jeremie investigated, he found out that X.A.N.A. had giving Aelita a virus that connects them both. If X.A.N.A. is destroyed, so does Aelita. With X.A.N.A. sending his monsters to attack Kadic, Aelita deactivates the tower and decides to stay in Lyoko in case X.A.N.A. would attack again. The Lyoko Warriors decide that Aelita would visit the Earth occasionally to visit for them. However...
The computer now shows the scenes from A Crack in Ed-Time.
Narrator: In another world, three unlikely boys who are New Cul-De-Sac's heroes went on an digitally adventure after discovering seven digital manga kids from the Digimon Universe while battling pirates, storms, and meeting a friend of wisdom of all beings called the Stranger. After defeating Captain Eric Cartman, The Digidestined went home or the digital world and the eds found a new home in the island of New Cul-De-Sac. And thus history was saved… for them at least.
The computer now shows something outside of Lyoko.
Narrator: As the digital adventure has ended, a new Lyoko adventure begins as a new foe appeared inside the Lyoko-verse. When Aelita is out of Lyoko, the Hunter is awakened to get her and something called Lyoko energy.
As the computer was closed, we see deep within a underground lair as a mysterious figure bursts in the door and wipe out all the guards in the lair. Meanwhile, Frank Hopper is guarding something when he senses someone approaching.
Franz Hopper: He's coming. Cover your butt.
Simon: Cover the what?
Neebs: I think he means cover our butts, Simon.
Simon: Ooooh. Why do we need to cover our butts?
Jakai busts in and does an evil laugh.
Jakai: Franz Hopper!
Franz Hopper: Jakai Hunter.
Jakai: You've hidden the Lyoko energy well, old man. (turning to his army of Men in Black) Men, destroy him!
Man in Black: Yes, sir!
Franz Hopper: Your men are no match for a Hopper, for I know every move you have! (they get immediately destroyed by a random punching glove, Franz Hopper was knocked out) Ouch!
After knocking down Franz, Jakai goes over to the Chest.
Jakai: The Lyoko goo, the most powerful energy source is mine. (he opens and sees it empty) What the?! It's gone! (Picks Franz up) Where is the Lyoko goo!
Franz Hopper: I'll never tell!
Jakai: Talk old men! I searched for and wide of your stupid project cardinge that you secretly made an energy source somewhere in your project. For I… am an evil energy collector of all worlds! I have collected magic, chi, and even jaded a few... masters along the way. But the one thing i need to take over the entire multiverse… is your finest energy source on how you make Lyoko so stable, so amazing and even so complex that even the scientists, who will discovered it soon, don't know what is capable of. So, Franz, or should I say… Waldo, where is it?
Jack: Sir! Sir!
Jakai: What is it, Minion Jack? I'm in the middle something.
Jack: We have detected the Lyoko goo! It's in some sort of girl with pink hair and it belongs to an… Hopper.
Jakai: So, the professor as a girl, huh. This girl is the one who will stop me and ruining my plans for world domination! (Drops him down) No matter. I must have her! (To Franz) Mock my words, Waldo, I will get your girl and that Lyoko goo out of her once and for all! My men in black will find her and capture her so I, Jakai Hunter, will RULE THE MULTIVERSE! Men in Black, we're done.
Men in Black: Yes, Jakai, sir.
Jakai and his army leaves.
Franz Hopper: They're going after Aelita! (Grabs a picture of him, his wife, and Aelita) Don't worry, Aelita. I know a safe place for you to be projected from him. A place called… Lyoko.
