"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! In the beginning of season 2, we witness the dawn of new technology. Jeremy programs vehicles into Lyoko for ... Written by Christapheo

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

very good, now quit comparing it with anime
9 September 2005 | by cheroldSee all my reviews

Shouldn't the protagonists of Code Lyoko all need therapy? I mean, think about the stress of having to save the world every day. Imagine having all your friends constantly almost die. It's amazing how resilient cartoon children are.

But the first thing I'd like to point out, in response to a lot of the comments here, that all animation does not have to look like Japanese anime. Really, it doesn't. It's not like all anime series look that great. Sure, Paranoia Agent or Cowboy Bebop are swell, but Pokemon is nothing to write home about. The French have made some very nice looking cartoons, like Fantastic Planet and Kaena. There are a lot of animators in France, in fact, and they have a perfect right to follow the French tradition of animation rather than the Japanese one. Of course, Code Lyoko is influenced by the Japanese, like most animation, but it is also in keeping with its countries products.

Personally, I really like the show's character design. It's one of the reasons I decided to check it out after seeing a commercial. A lot of cartoons look like a lot of other cartoons, and the distinctive faces attracted me to Lyoko and made me think it might be more than just another cookie cutter cartoon.

Lyoko is a rather odd show, because each episode is structured in almost exactly the same way. The evil computer virus accesses the real world, the heroes go into the virtual world and kill some monsters, and everything is fixed and time is reset to before the disaster (I haven't seen the early episodes so I don't know if they explain why or how time is reset; this show doesn't seem that interested in details).

Lyoko is definitely a kid's cartoon, even though I enjoy it. It's not as sophisticated as Batman or Trigun, but characters are distinct, there are some interesting ideas, and it does have a nice look to it. It's not a great cartoon series, but it's a good one.
