In another lucid moment, Dr. Eliot locks himself in an hermetically sealed room and smashes the only electronic keypad for the door; and he and the energy force which has possessed him expire. As Kronos draws near Los Angeles, Gaskell realizes that reversing the monster machine's polarity will force it to feed upon itself, until it is destroys itself in a gigantic implosion. Gaskell, Culver and Vera convince the Air Force to bombard Kronos with nuclear ions which will cause the polarity to be reversed; this experiment works, and Kronos is obliterated in the resulting implosion.
