Plot
The first season of the series focuses more on character development than plot development, only revealing details about the plot in its last few episodes. The rest of the episodes are "filler" because, in each episode, the Lyoko Warriors discover a X.A.N.A. attack, fight against it, stop it and activate a return to the past for one single day.
As a complement to avoid the monotony of the series, this season shows relationships between characters and other students and teachers of the school with their parents, relatives, etc. During all this, Jeremie is working on a program to "materialize" Aelita (transport her from the virtual world to the real world) so that they can turn off the supercomputer and, therefore, X.A.N.A. once and for all.
Story
X.A.N.A. Awakens
X.A.N.A.'s first attack.
As Jeremie Belpois is looking for parts to use 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". As Jeremie found out about the scanners and virtualization, he sent Odd Della Robbia and Ulrich Stern to Lyoko. They didn't meet Aelita because they were devirtualized by Bloks in the Ice Sector, but not before Ulrich spots a strange red Tower in the same Sector. Feeling the pulsation from the red tower, Aelita heading to the Ice Sector through a Way Tower.
Jeremie wanted to fully materialize Aelita on Earth, so they can shut down the supercomputer and neutralize X.A.N.A. for good. He had confided in Odd, Ulrich and Sissi that they could do it if they could get Aelita into the red tower (a tower which X.A.N.A. had activated when Jeremie restarted the supercomputer) in the Ice Sector. However, Sissi gets electrocuted by an electric energy orb sent by X.A.N.A. and Ulrich brings Yumi Ishiyama to the factory. Jeremie sends Ulrich, Odd and Yumi to Lyoko to help Aelita get to the tower after an fierce fight with X.A.N.A.'s monsters. As Aelita saw the interface, she found out that her name wasn't Maya, but Aelita. She deactivates the tower. However, Jeremie's theory was wrong as Aelita didn't come to Earth. Aelita thinks that keeping the supercomputer on is too dangerous and that they should shut it down immediately, but the others agreed to keep fighting X.A.N.A until Jeremie finds a way to materialize Aelita. (X.A.N.A. Awakens)
Aelita's Materialization Program
Jeremie programmed an almost working version in Cruel Dilemma. But it wasn't until he left, and Odd accidentally pressed a few keys that weren't known, which made the program workable. Since nobody knew the full contents of the program, it couldn't be recreated. For an unspecified reason, it wasn't re-usable. Because of these two facts, it was a single-use program. Yumi fell into the Digital Sea later in the episode, and they had to use the program on her instead. This version was the only Materialization program that was able to recover a body from the digital sea. Unlike the later versions, it didn't require the target to be in a Tower to work. In Just in Time, Jeremie managed to create a materialization program which actually worked. Since he was unsure if it would work correctly or not, he tested it by materializing a single hair of hers. This worked, but in the process, his program bugged up the Annex Program, so that if Aelita used Code: Lyoko, she would be deleted. Exactly that happened, so the group used the hair to clone her and recover her data. In Frontier, when Aelita and Jeremie try to do more tests on materialization, Aelita accidently does some preparations that Jeremie had already done, causing Jeremie to get mad at her. As Jeremie thinks he hurt Aelita, he decides to go into Lyoko by himself, but an error occurs, moving Jeremie somewhere between Lyoko and Earth. Aelita, who is connected to Jeremies' thoughts, activates four towers from four sectors, bringing Jeremie safely back to Earth just before the supercomputer had him erased. During Ghost Channel, Odd, Yumi and Ulrich dissappeared during Return To The Past. Aelita finds out that X.A.N.A had created a virtual reality to trick the missing trio into thinking that they were actually back in the real world. As Jeremie virtualized himself to save the others, Aelita used her abilities to destroy the illusion, freeing the others from X.A.N.A.'s mercy. (Cruel Dilemma, The Girl of the Dreams, Just in Time, Frontier, Ghost Channel)
Aelita is finally Materialized
Aelita finally materialized.
In Code: Earth, 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 Odd's cousin and Yumi had her parents convinced about her 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 given Aelita a virus that connects them both. If X.A.N.A. is destroyed, so is 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. (Code: Earth, False Start).

Trivia
- If one adds the 2-part prequel, then Season 1 would consist of 28 episodes rather than 26.
- This was the only season of not made by Moonscoop. It was instead made by Antefilms, prior to their merger with France Animation.
- This season had more English DVD releases than the other seasons combined. In fact, the entire season, has been released by two companies. In addition, 3 partial sets have been released.
- Odd's only ability on Lyoko is "Future Flash," allowing him to see imminent danger to his friends or hidden paths. It is used only in four episodes and is lost after this season.
- It is mentioned throughout the season that Aelita's presence on Lyoko is the only thing keeping X.A.N.A. alive. It is unclear at this time if X.A.N.A. is aware of this, however, since he frequently sends his monsters to try and kill Aelita.
