Invasion of Astro-Monster  (known in Japan as The Great Monster War (怪獣大戦争 Kaijū Daisensō?) re-released in a shortened edition as The Great Monster War: King Ghidorah vs. Godzilla for the Champion Festival in 1971. In English speaking regions it is known as Godzilla vs. Monster Zero, Monster Zero, Invasion of Astro-Monster, Invasion of the Astro-Monsters, and Invasion of the Astros and experienced superficial changes for its localization.

Set in the ambiguous year of "196X", it is the fifth film in the Godzilla series. Released internationally under a wide assortment of titles, it was the last film special effects director Eiji Tsuburaya would helm entirely on his own. Director Ishiro Honda would be also appointed to Toho's secondary special effects films for the next two years before returning to Godzilla for Destroy All Monsters (1968).
