Sardath attempts to control Adam's Zeta-Beam visits to Rann, but a side-effect gives Adam a super-evolved brain which also creates a brain-wave menace for the planet. When Alanna shuts down Sardath's machine, all returns to normal but some of the brain-wave energy becomes frozen into a rock which Adam takes back to Earth.
