The Desert Replika is one of replikas of Lyoko which were created by X.A.N.A. It was the first Replika to be found through Jeremie's updated Superscan, first shown in A Lack of Goodwill. This Replika contained the Desert Sector and its supercomputer was located in the lower levels of the New Mexico Research Facility.
This Replika was destroyed in Hard Luck when Ulrich stabbed his sabers into the supercomputer's core, before he was devirtualized due to a bug.
In Code Lyoko: Quest for Infinity, the Desert Replika has a similar appearance to the Desert Sector, but the layout is different.
