The tornado of X.A.N.A.A tower activated by X.A.N.A.A normal tower

There are many types of monsters in Lyoko. Xana creates them in order to keep the towers it activates safe. Some are a mere nuisance while others are a major threat. The ones that can be considered a nuisance make up for this fact by travelling in packs. All of them, however, try to impede the group. The monsters remain until they are destroyed or a return trip is activated. Xana has eleven types of monsters so far. Odd, Ulrich and Yumi each have special weapons in Lyoko in order to destroy the monsters. Aelita mostly relies on the protection of the others when it comes to dealing with the monsters in the first two seasons, but gains a weapon in the third.

Other monsters exist that don't fall into the same category as Xana's monsters. One is a monster Jeremy produced, called the Marabounta. It appears in only one episode. There is also an entity known as the Transport Orb. It's a giant white sphere with an Eye of Xana printed on it, like all of Xana's monsters. Unlike the other monsters, however, its only purpose is to ferry passengers from the edge of any region to the center of the fifth sector, Carthage, and back again. Both Jeremy and Xana can access it at will. This entity's classification as a monster is arguable, but it is included for the sake of completion.

Also, there are monsters, located in the digital sea. These monsters must be destroyed using torpedoes shot from the Skidbladnir or Nav Skids.

The main characters are Aelita, Jeremy Belpois, Odd Della Robbia, Ulrich Stern, Yumi Ishiyama, William Dunbar, and Xana. There are also several supporting characters that appear in most of the episodes. These two groups make up the primary cast for the show.

The artificial intelligence known as Xana is obsessed with world domination. Towards that end, he has taken over the supercomputer in charge of the virtual world of Lyoko, which he largely dominates. Xana is also able to attack the real world by activating towers (usually one at a time), which act as links to the real world. When these towers are activated, Xana is able to seize control of other computers and electrical systems as well as occasionally possessing organic life-forms or generating copies of them. The group has to get Aelita to the activated tower(s) out of the forty scattered about Lyoko's four main regions to deactivate them, neutralizing Xana's attack on the real world.Once the danger is averted, they can use the supercomputer to return to the past, leaving no one except themselves to remember any of the events that transpired. To complicate the situation, they must do this while ensuring their ****ates and teachers are not killed (as going back in time cannot bring back the dead), and deal with the many clashes of personality at the same time. The time travel only goes back roughly a day, taking back anyone who has been scanned in one of the scanners. once back in time, they can use their knowledge of the future to alter events in their favor or the favor of others. This usually entails taking steps to keep one of Xana's attacks from taking place, though they do use the knowledge to prevent other unfavorable events that might not be related to Xana, such as the destruction of Jeremy's Kiwi 2 robot in "The Robots". However, as a downside, returning to the past adds a qubit to the supercomputer, doubling its power and therefore Xana's with each use.

Code Lyoko is about a group of five boarding school students enrolled at Kadic Junior High School: Aelita, Jeremy Belpois, Odd Della Robbia, Ulrich Stern, and Yumi Ishiyama. The students travel to the virtual world of Lyoko - which is found in a supercomputer housed in the basement of an abandoned factory near the school - to fight against a megalomaniacal digital entity named Xana.
