Gigan

Gigan (ガイガン, Gaigan?) is a kaiju (Japanese giant monster) from the Godzilla series, introduced in the 1972 film Godzilla vs. Gigan. Gigan is an organic/cybernetic monster sporting a buzzsaw weapon in its frontal abdominal region and large metallic hooks for hands. Gigan is considered Godzilla's most brutal and violent opponent, alongside Destroyah, both of which were easily able to severely injure Godzilla. Gigan was also the first monster in the Toho sci-fi series to cause Godzilla to visibly bleed.
