Virtualization is the process of an entity being transferred onto Lyoko.

The process was first chronologically used on humans with Waldo Schaeffer and his daughter, Aelita, for them to escape to Lyoko from the men in black. It may have been invented by Waldo.

The process is usually run by Jeremie, Aelita, or by the Self Virtualization Program.


The only possible way (shown in the series) to do this is to use the scanners. The process is not fully detailed but it appears to be broken into stages.

  1. Transfer: The first stage is avatar recognition. Jeremie selects an avatar and the computer realizes the stored genetic structure of the Lyoko Warrior.
  2. Scanner: The second stage is scanning. The person's molecular structure is identified and stored if the person is being virtualized for the first time; if the Supercomputer already recorded their virtualization beforehand it will simply be recognized.
  3. Virtualization: The third stage is the final virtualization; this consists of the character's "digitization" (conversion from physical matter into digital matter) and finally, their appearance on Lyoko.

This process can have mistakes, both due to operator error and machine error. Instances of this include:

It's revealed in Code Lyoko Evolution that after a person is devirtualized, they cannot be revirtualized until 12 hours pass. This serves as a retcon because several instances exist in the original series where a character is revirtualized after less than 12 hours. In Common Interest for example, Odd was virtualized with Ulrich to do a sweep of the Ice Sector to locate an activated tower. Jeremie brought both of them back to pick up Aelita who was recovering in the hospital. Odd was then virtualized again with Aelita and Yumi not much later in the same day to help Aelita deactivate the tower.

According to an interview with Sophie Decroisette, there wasn't a set timeframe in the original series and the characters were said to wait some time between virtualizations due to being too exhausted, whether from fighting on Lyoko or from the process itself.[1]
