During the past year or so I've been constructing what I consider to be the complete Godzilla cannon. These are films that exist in the same universe as Godzilla whether directly or indirectly. Feel free to ask questions for this is still a work in progress. My goal is to buy every single one of these films and I'm down to only having like 20 left. To be in the cannon, a film must share characters, kaiju, robots, or anything of the like. As well as a film that is mentioned or implied (like Half Human). Only movie connections though, so games, comics, tv shows, or anything else is not going to count as cannon. Only movie connections. Showa: Gojira (Godzilla: King of the Monsters) Godzilla Raids Again (Gigantis the Fire Monster) Half Human (Monster Snowman) Rodan The Mysterians Varan the Unbelievable The Three Treasures (Birth of Japan) Battle in Outer Space (Great Space War) Mothra King Kong vs. Godzilla Gorath Atragon Matango (Attack of the Mushroom People) Mothra vs. Godzilla (Godzilla vs. The Thing) Dogora Ghidorah, the Three-Headed Monster (The Giant Monsters: Greatest Battle on Earth) Invasion of the Astro-Monster (Godzilla vs. Monster Zero) Frankenstein vs. Baragon (Frankenstein Conquers the World) Ebirah, Horror of the Deep (Godzilla vs. the Sea Monster) The War of the Gargantuas (Frankenstein’s Monsters: Sanda vs. Gaira) Son of Godzilla King Kong Escapes Destroy All Monsters Latitude Zero All Monsters Attack (Godzilla’s Revenge) Space Amoeba (Yog, Monster from Space) Godzilla vs. Hedorah (Godzilla vs. the Smog Monster) Godzilla vs. Gigan (Godzilla on Monster Island) Go!
