As a child, George was given the charge to guard the Clock of Changes by a cosmic being called the Overchron. It gives its possessor the ability to travel forward or backward in time to any era he wishes. At first, the child was pure and steadfast in the keeping of the Clock, but as he got older, the desire to fiddle with time itself became too great. He soon became addicted to traveling through the ages, causing mischief wherever he went. He even learned how to manipulate time into an extremely destructive weapon. In a possible future, Chronos’s descent into villainy prompted the creating of the Clocksmen, a temporal force of time-travelling soldiers tasked with finding and neutralizing Chronos. It was this villain who created a tidal wave in the time stream that wiped out every clocksman except for Countdown, who must now carry on the clocksmen’s mission alone and with revenge as an added motivator. Now, completely warped by his obsession, Chronos aspires to make himself into a virtual god.
During a showdown that spanned several millenia existing simultaneously, Countdown finally confronted and defeated Chronos by destroying the Clock of Changes and leaving George stranded in the year 1,472,908 BC.
George was found nearly dead by a tribe of Neanderthal men and taken into their group. He eventually became one of them and sired a strange, hybrid daughter with one of the Neanderthal women. This little girl would grow to become one of the most catastrophic forces on Earth.
