Ever since Marty had his first contact with the Black Armors and was subsequently rescued, he has been found to possess mysterious prophetic abilities as he is able to see the future in fragmented visions portraying an avalanche, a tsunami, a storm and other catastrophes. These disasters will always come true after Marty experiences the prophetic visions, but he is unable to predict accurately when and where they will occur. When the government learns about this, a unit is sent to protect Marty, and World Peacekeepers, abbreviated as WPK, is established to fight against the Black Armors. In order to defeat the Black Armors, the government grants permission for World Peacekeepers to use Ammobots – mechanical armors which have been developed over many years.
