All seven armies are beneath the supreme command of the Great General of Darkness. After his defeat and death at the hands of Great Mazinger, the Great Marshall of Hell took over the supreme command. However, it can be noted that there is an unofficial eighth battle beast army; the "Chouhou" or Multicapable/Intelligence (or convenience) Battle Beasts. These are more robotic and mechanical in nature than other Battle Beasts and displayed characteristics that could not be easily classified into one of the seven normal armies. In addition, they share the same name as Minister Argos, implying the robotic factor of the beasts. Another title for them could have also been Indeterminate Battle Beasts.
