An African general named John M'Butu, a fast-rising tribal leader gifted with a powerful psychic suggestion ability and calling himself the Voice, is leading a genocidal campaign in the Salawe region of Uganda. The US government identifies him as a superhuman after he survives an assassination attempt. The team is sent to the region to assassinate him, but early in the fight, Hyperion, Doctor Spectrum and Amphibian are affected by M'Butu's power to control anyone who hears his voice. M'Butu commands the trio to hunt down their comrades. Zarda immediately notices that there is another voice in Hyperion's head and not the One True Voice. Zarda manages to free Doctor Spectrum by calling to the voice within the Power Prism, which takes control of Spectrum, and frees Hyperion.
