 The concept of this movie is a mix of elements from the movie  _Destroy All Monsters (1968)_ (qv), and the games “Godzilla: Monster  Of Monsters” and “Godzilla: Destroy All Monsters Melee”. It uses the  idea of alien invaders coming to earth with an army of monsters at  their disposal, having Godzilla being able to avoid control and  fight the army of monsters in various cities and areas across the  world comes from “Godzilla: Destroy All Monsters Melee”, and Mothra  being his only real ally was used in “Godzilla: Monster Of  Monsters”.
