In Down to Earth, the early version of the program was used to temporarily immobilize the Kolossus in ice lake in the Ice Replika. The main function of the program, however, was to destroy X.A.N.A., although it is revealed in Down to Earth that the early version of the program could wipe out minor manifestations of X.A.N.A. (namely his monsters except for the Kolossus, with Jeremie specifying that he could destroy up to three Megatanks).
To fully destroy X.A.N.A., the program required setting up in Sector Five's interface and ended up having high energy requirements, far more than what the Supercomputer could normally provide. When Aelita first activated the program in Fight to the Finish, it failed due to a lack of energy. Franz Hopper then sacrificed himself and his energy allowed the program to become operational and X.A.N.A. was finally destroyed. The program was an example of both an Artificial Intelligence and a Multi-Agent System.
