The Volcano Replika is X.A.N.A.'s main Replika in the Digital Sea. Unlike all other Replikas, it is not based on an already-existing sector of Lyoko. It was introduced in the second Code Lyoko game; Code Lyoko: Quest for Infinity. It has never existed in the show and is made purely for the video game.
It is a volcanic "continent" consisting of volcanoes and lava pits. There are many obstacles and lava flows throughout this area. It has a large crater filled with Towers, which is said to be the core of X.A.N.A. The Volcano Replika is one of the hardest areas to move around in.
In the game, it is home of the data that could be used to save William from X.A.N.A.'s clutches. It is the final level in the game and is destroyed when Odd and Aelita destroy the supercomputer killing X.A.N.A. and freeing William at the same time.
It also appears in the Code Lyoko comics where it is used by X.A.N.A. as dumping ground for failed monsters.
