Gyaoon was one of the first Pokemon ever designed. It was dropped around the end of the development of Pokemon Red and Green, probably because its too obvious resemblance with Godzilla. It is highly likely that it have been redesigned by Sugimori years later, giving us the Tyranitar we all know nowadays.
Gyaoon is basically the sound of Godzilla's cry.
Note: That hatching location was chosen because it both matches the "abandoned nature" of Gyaoon and the damaged places by Kaijus.
