Kongou (金剛) is a fighting game character from the fantasy-themed arcade game Red Earth, where he is one of the eight unplayable boss characters.
Kongou was once a mere human named Tanuma (タヌマ) from Zipang. He was a portly merchant with no fighting ability, but then he met Scion, who bestowed upon him the ability to transform into a great ogre. Now known as Kongou, he is terrorizing his own homeland, wielding a massive spiked club and reducing those who stand in his way to nothing.
- Kongou, along with Gi Gi, made a cameo appearance in Jedah's ending in Capcom Fighting Evolution.
- Kongou, along with Ravange, also made a cameo appearance in Hsien-Ko's ending in Ultimate Marvel vs. Capcom 3.
- His name means 'Diamond' or 'Indestructible' in the Japanese language, most likely referring to his strength and might.
