The Chimera Code was only seen in the game Quest for Infinity. Its primary function is to destroy Replikas. Aelita used this code to destroy the Desert and Ice Replikas after the Lyoko Warriors discovered them.
The code must be used in the main tower of the Replika in order to destroy it. In the other towers, it won't work and Aelita would use Code: Lyoko instead. It only destroys the Replika at hand, and not the Supercomputer in question, which means X.A.N.A. still controls it.
- The code is possibly named after the Greek Chimera, a monster with the tail of a snake, body of a goat, head of a lion, and face of a man.
