This is an report of an alternate reality in which Emperor Digimon was victorious!
Beel-Zmon is a 3rd generation experimental project, and just as mechanization was intended to improve the mons, so was this experiment, but in a different way. An impmon was discovered who never found his destiny, his human partners, because the war reached the earth and devastated it, Emperor then took this impmon in with ulterior motives and treated him as badly as he could, feeding his anger to the point of mental exhaustion, and it was at this point that he put into practice the Z Experiment ☠️, which was a total failure for humanity but another victory for the sadistic Emperor!
