La nuova follia di Verybad

Among the machines invented by Hellingen there is one that Adolfo Verybad managed to make work and make available to the United States government. Too bad that the diabolical invention ends up in the wrong hands and Professor Verybad is captured by an unscrupulous businessman, Mister Blake, who forces him to use it for his criminal purposes. In fact, the device allows the mind of one man to be transferred into the body of another and, when Zagor is also subjected to the incredible machine, no one seems able to stop Blake's plans!
