When the tower that Alexander Luthor used to recreate the original Multiverse during the events of "Infinite Crisis" was destroyed, a "seed programming" was activated that created a Monitor for each of the 52 Earths of the new Multiverse born in that moment. Since this new Multiverse consisted of 52 identical Earths at the time of its forming, all 52 Monitors would have been identical. However, following the events of "52", the Monitors began to evolve and acquire increasingly divergent identities in physicality and disposition. As the Monitors evolved, their story became more complex, a "self-assembling hyper story".
