X.A.N.A. 2.0 is the first episode of Code Lyoko Evolution and the overall ninety-sixth episode of Code Lyoko.


After defeating X.A.N.A. and shutting down the Supercomputer the previous year, the Lyoko Warriors have been enjoying normal lives. However, they notice that something extremely familiar is happening again. After the school's speakers explode, they decide to restart the Supercomputer to check whether there was something strange on Lyoko (this is being done without William).

Jeremie informs the team that the Forest and Ice Sectors have disappeared due to the long period of time in which the Supercomputer was shut down. Aelita and Odd go to Sector Five to see whether or not X.A.N.A. was behind the incidents at KadicYumi and Ulrich then leave the factory.

After Jeremie virtualizes Aelita and Odd, a tower is suddenly activated. Three Megatanks appear in front of them. They managed to destroy two of them, but Odd is devirtualized afterwards.

On Earth, in the gymnasium, a polymorphic clone disguised as Jim attacks Yumi and Ulrich. "Jim" grabs onto Ulrich, and Ulrich suddenly becomes blind. The two rush to the sewers and Yumi leaves Ulrich in the sewer tunnel and hurries to help Aelita on Lyoko. They defeat the last Megatank. However, two Krabs arrive. Odd goes to save Ulrich. However, the spectre catches up and attempts to attack Ulrich. Odd blocks the spectre, and is mysteriously injured as well. After a short battle, Aelita manages to deactivate the tower.

Sometime later, Jeremie discovers that X.A.N.A. implemented his codes inside of Aelita, Odd, Ulrich and Yumi, which allowed him to survive his defeat, and is now working to reclaim his codes. Jeremie also reveals that X.A.N.A. was not in anywhere inside Lyoko, but somewhere in the network itself.


  • Set approximately six months after the end of the original series. This also represents the longest gap between X.A.N.A. attacks.
  • From this episode on, the title card no longer lists who storyboarded the episode. Instead a credit for head writer David Carayon takes its place and a generic list of every storyboarder involved with the series is used in the end credits.
  • Adherently similar to the episode Franz Hopper, in the way that Sector Five is designed to make the group look for the activated tower and not expecting one and find a "new" tower that apparently is not only existing, but has been active for a while.
  • This was the only episode in Season 5 that premiered in 2012.
  • While sparring with Ulrich, Yumi's hairdo resembles that of her original Lyoko form.
  • A return to the past is not shown to be launched in this episode, so Jim may remember the fact that a duplicate of himself materialized out of thin air and zapped him.
  • Any monster can access Sector Five now.

Production Notes[]

  • Monsters explode differently when they are defeated.
  • Towers have now been squared out, and do not feature the glow that was present in the original series. Instead, when a tower is activated, parts of it move out from the main body to reveal a glowing red interior.
  • The animation detail has been improved.
  • Avatars have been redone to show eye color and more expressions; the size of heads has also been reduced.
  • Megatanks' lasers are also shorter. Instead of having a long continuous laser that is almost a wall, it is a quick, thick outline of a circle.
  • The interface of the tower has also been modified slightly.
  • This is the first episode to use live-action footage for the scenes in the real world.
