History: The Hyper Gyaos were an evolved form of the Gyaos monsters that were Gamera's archenemies. He fought against three of them in Tokyo, and prevailed thanks to his fireballs, which burned the monsters to death. However, the battle was hugely destructive, as Gamera's hatred of the Gyaos caused him to be oblivious to the humans he had once protected.
