But the P.L.O.O.P. thaught to reverse this process with dark energy to make creatures go berserk but still this was not enough then one of the P.L.O.O.P. member Prince Maurice, the Merciless, he even thaught of a way of cloning them and mass producing them as well so that every member of their army can comtrol these creatures in huge amounts.
