"Code Lyoko" tells the story of a group of students who uncover a parallel universe called Lyoko inside a super-computer that is threatened by a renegade program named XANA that could destroy the world. It's up to four boarding-school students named Jeremy, Yumi, Ulrich, and Odd to help a humanoid being inside Lyoko named Aelita to stop the rogue program XANA and his plans to attack their world. Jeremy, who is in love with Aelita, struggles through season 1 to find a way to "materialize" Aelita, so she can become human by exiting the scanners that connect Odd, Ulrich, and Yumi to Lyoko. If Jeremy accomplishes this, he will be able to shut down Lyoko and defeat XANA. We witness Jeremy finally materializes Aelita, and accomplish his dream. The group deactivate Lyoko, but XANA apparently infected Aelita with a virus before she was materialized so that if XANA goes, she does too!

Code Lyoko transfer from 2D to 3D inspired the crossover of Jimmy Neutron and Timmy Turner in the Jimmy Timmy: Power Hour. See more »


The time it takes for the Scyphozoa to steal Aelita's memories in the second season of the Code: Lyoko progressively changes throughout episodes, and conflicts with the storyboard. A clear example of this is shown in "The Key", where the Scyphozoa manages to steal Aelita's memory seconds after it captures her. This conflicts with the previous episodes, where several minutes would pass and the Scyphozoa would still not have obtained Aelita's memories. See more »

User Reviews

Has problems, but a fine show.
8 October 2004 | by AmericanLyokoTeamSee all my reviews

Code Lyoko has both good and detrimental points. For a cartoon, it actually requires some effort to follow. Episodes are serial, but usually contain enough individually packaged information to give you a sense of what is going on.

Some of the positive points are: For a cartoon, Code Lyoko has an interesting amount of writing and character development. The set up for the show is also very interesting, adding a sci-fi element. The Characters are broad based, and while they play set roles, they can occasionally do something developmental. The action in the show is interesting, and although small scale, seems to have the appropriate tension associated with it. The computer graphics portion of the art is quite well done, reminiscent of shows like Reboot.

Some negative things about the show: The dub is of rather poor quality. Characters lines are often rushed to match existing footage. There are a distracting amount of stock scenes in any given episode. Also there are many goofs, but most of those are related to the stock scenes. Some people may not like the ultra-angular hand drawn portion of the art, especially noted are that people's heads are drawn very large.

With all that said, I still recommend this show. You'll get enough enjoyment out of just following the plot and characters to make up for the poorer features.
