The XANA Faction represents those controlled by XANA. Their purpose is to take over Earth and the Network and as such, are hostile to both the Lyoko and Cortex factions.
Most Monsters are part of this faction, but players can also join it by becoming permanently xanafied. To accomplish this, they must destroy Lyoko's core within Sector Five after getting xanafied by the Scyphozoa.
Once a player becomes permanently xanafied, they are sent to XANA's Void, in which they will remain whenever they are not out on a mission. They will have a cooldown whose duration depends on XANA's AI level and whether they were devirtualized back to the Void or if they simply fell into the digital sea.
XANA will automatically send out a xanawarrior whose cooldown is over whenever it starts a Core attack or a Tower Attack, notifying everyone in the faction of it at the same time. However, a xanawarrior's cooldown does not need to be over to be sent out on Earth for a Translated Xanawarrior attack if it is automatically launched by XANA.
| AI Level | Digital Sea | Devirtualization |
|---|---|---|
| 1 | 5:00 | 10:00 |
| 2 | 4:30 | 9:00 |
| 3 | 3:45 | 7:30 |
| 4 | 3:00 | 6:00 |
In addition to a lower cooldown, xanawarriors coming back to the Void through the digital sea will be able to keep the energy they collected for their next virtualization. Just like temporarily xanafied players, they can steal the energy of their enemy by devirtualizing them.
Players in the Void can open XANA's terminal to execute certain actions or obtain information by pressing the same keys as for the virtual menu (Shift + L by default):
There can be a maximum of 5 xanawarriors on the server at once. If a 6th one joins the server or the faction, one of the 5 others will automatically be freed. If a xanawarrior is already active outside of the Void, the others can not manually decide to leave it but XANA will still be able to send them out. Permanent xanafication will be automatically lost when joining the server after 48 hours.
There are two ways to liberate a xanawarrior.
If a xanawarrior is materialized on Earth through a scanner, they will have 5 minutes to go back to the Void or their connection to XANA will be cut. Knocking them out will instantly lower the timer by 30 seconds.
While a xanawarrior is translated through a Translated Xanawarrior attack, their data will be vulnerable within the activated tower through the Translation process. If they virtualize while translated, it will instead be replaced by a temporary Translation Data Remnant process, also containing the data.
Up to three players can interact with both of these processes to obtain the Knowledge to launch the liberation process from the Remote Tower Control Program in the lab. The liberation process costs 100 energy to execute but does not need to be launched in an activated Tower. Doing so will consume the liberation knowledge no matter if it ends in a success or not, and as such will have to be obtained again.
Once the liberation process is launched, the players will have 5 minutes to devirtualize the xanawarrior. During this period, the xanawarrior will be unable to go back to the Void at all. If the xanawarrior is successfully devirtualized or falls into the digital sea, they will appear back in a scanner, no longer under XANA's control.
