Fan:Crystalloid Army of Darkness

The Crystalloid Army of Darkness, or CAD, is an army and organization of mostly machine and evil Digimon that are bent upon conquering the Digital World and rebuilding it from scratch. They often make deals with Digimon that are respected in the Digital World, most often conning their clients and if necessary use brute force to keep their clients from avoiding their demands. They are not a trusted organization among good Digimon, but somehow less good Digi-cored Digimon always get tricked into signing a deal with the devil.
