Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack
Again disregarding the continuity of previous films of the millennium series, the Godzilla in Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack is confirmed to be the original monster (because of the American’s mistake of misconfirming Zilla as the true Godzilla), now driven by the souls of those who died in the Pacific in World War II.
This film returns Godzilla to his roots of being a genuinely malevolent being who deliberately seeks to punish Japan for the sins of WWII. Godzilla would do battle with the Yamato beasts Baragon, Mothra, and King Ghidorah but would be nearly destroyed by the actions of General Tachibana, who piloted a submersible down Godzilla’s throat and out through a wound in his neck.
The next two times Godzilla attempted to use his atomic breath it shot out of his wound, and eventually tore him apart from the inside. At the bottom of TokyoBay the monster’s heart lived on, continuing to beat.
