- Awesome Music: While the music was indeed lifted from other sources, one cannot deny that the editors were very wise with the selections that they chose, since this would be the last film until Godzilla vs. Mechagodzilla II to feature Godzilla's theme as it was heard in Mothra vs. Godzilla. The music from Mitsubishi Pavilion is also very wonderful and when it's used during Anguirus's friendship moment. It strikes a chord. What's not recycled, is Kunio Miyauchi's catchy Godzilla March as sung by Susumi Ishikawa.
- Complete Monster: The titular monster, Ghidorah's Dragon Gigan, was nearly as vicious as his compatriot, burning most of Tokyo to the ground, laughing all the while. What truly made Gigan stand out, however, was his sadistic love of hurting others. During his and Ghidorah's battle with Godzilla and Anguirus, Gigan repeatedly opted to go for torture rather than finishing an opponent off, dragging the other monsters in close and using his buzzsaw to carve pieces off of them, and showing a distinct preference for targeting those who could not fight back, attacking a severely wounded Godzilla while he lay bleeding on the ground, and later, in Godzilla vs. Megalon, teaming with Megalon to deliver a No-Holds-Barred Beatdown to Jet Jaguar. Prone to abandoning his allies as soon as the going gets tough, and hating a fair fight, Gigan was Toho's reigning king of Kick Them While They Are Down.
- Ensemble Dark Horse: Gigan's only other movie appearance in the Showa-Era would be the next film, Godzilla vs. Megalon, which is just as bad, but was so popular he came back as one of the major villains in Godzilla: Final Wars.
- Memetic Mutation: Shosaku "Corn Guy" Takasugi is popular amongst G-Fans for being so fascinatingly inexplicable◊.
- From the dub; "I think it stinks!"
- Narm Charm: Like many Showa-era Godzilla movies, this one is most definitely not a cinematic masterpiece but it has its moments. Fans really seemed to like Gigan himself, and the climatic battle (when its not using Stock Footage) has some memorable moments such as Gigan being the first villain to make Godzilla bleed and Angurius's Friendship Moment.
- Special Effect Failure:
- During King Ghidorah and Gigan's entrance, they are clearly completely stiff toys.
- When Gigan steps on a car, it is clearly a toy car.
- The Godzilla suit, SoshingekiGoji (which had been made in 1968 for Destroy All Monsters and used in subsequent films up to this one), was in such bad shape that it was visibly falling apart.
- King Ghidorah's suit, being the only one made during the Showa era and having already been in three previous films, was in pretty bad shape as well. In all of its non-stock footage scenes it's very still most of the time with only some slow head movement to prevent it from falling apart during filming.
YMMV / Godzilla vs. Gigan
