The Ice Replika is a Replika found in Season 4 and is a copy of the Ice Sector that X.A.N.A. made. It is both seen in the show and the game. It was also the place where the Lyoko Warriors managed to free William from X.A.N.A.'s clutches. Furthermore, this was where the Kolossus made its first appearance. In order to destroy this Replika, the group had to destroy the main supercomputer, located in the Siberian Research Facility, the function of which was to create an army of robots.

This Replika has the only known supercomputer that was never destroyed physically, because during the first trip, Odd and Yumi had to be translated back to the Replika at the last second so the Kolossus wouldn't destroy the Skid. It was also because the second trip to the Replika was more focused on saving William from X.A.N.A..

It could be assumed that it shut down after X.A.N.A. was destroyed in Fight to the Finish. The Ice Replika appeared in Cold Sweat and Down to Earth.

In Quest for Infinity, the facility holding the Ice Replika is where the Ice Spider appeared. In the game, the Ice Replika had the same appearance of the Ice Sector, but had a different layout, as opposed to the show, where the layout was the same as well. This is where Odd unlocks his Catclimb ability.

The Ice Replika also appears in Code Lyoko: Fall of X.A.N.A.. In the Replika, there are several bugs in the map, which allow things such as monster encounter through force fields, walking through solid walls, and getting trapped.


  • This was the last of Season 4's Replikas shown.
  • This was where the Skidbladnir was destroyed.
  • The Kolossus first appeared in this Replika, and also only in the original Ice Sector.
  • In Cold Sweat, X.A.N.A. activated a tower on this Replika to send William to the Siberian Base. Aelita was able to access the tower located here, which contained the programs for controlling him. This later allowed them to reverse engineer the program to free William.
