XANA's Monsters

To defend his towers and to battle the group in Lyoko, Xana creates and sends monsters to devirtualize them. Each of Xana's monsters has a common trait: the Eye of Xana. This serves as their weak point and, in some cases, an actual eye. A single hit to this part of their body with one of the warrior's weapons will destroy it. They can also be destroyed in other ways, such as being hit by a partner's laser by accident, struck against walls, cast into the digital void, or crushed. With a few exceptions, each monster also has a laser weapon of varying strength, as well as secondary weapons in some cases. The monsters have varying levels of intelligence, which is often directly related to their overall strength. Finally, the monsters usually have fifty life points unless otherwise noted.

Most monsters have the ability to aim their laser, though they do not seem to do so often. This is shown from the monster's point of view, which is dominated by a trisected, white circle. When targeting something, an upside-down, red triangle follows what they intend to shoot. When it locks on, the red triangle centers within the circle and three red lines connect each vertex of the triangle to the circle. Only a few monsters have directly demonstrated this targeting system, but it is safe to assume that others utilize the same system.

Finally, due to natural faults in translation, it is not unknown for a monster to be renamed in the English version. This is most commonly seen with the Frelions/Frôlions, which are called Hornets or, rarely, Waspters. The Kankrelats were also called Roachsters in the first season, but they are now called by their original name. Each monster is listed with its current English name. Unless otherwise noted, their name in French is the same as it is in English.
