Rayquaza is the English name for a Pokémon originally named "Rekkuzza" in Japan. The English name was assigned by Nintendo of America.
In Hoenn, an island region in the Pokémon world, legend states that this creature, the "Master of the Skies," once descended from the clouds to end a cataclysmic battle between the Earth Titan "Groudon" and the Sea Titan "Kyogre." Occording to legend, the battle almost destroyed the earth. Had Rayquaza not ended the fight, all would be lost.
Thousands of years later, Rayquaza laid to rest atop a tall tower built long ago known as "Sky Pillar." It slept for years until a young child came and awoke it once more, as the evil organizations Team Magma and Team Aqua had called forth the Titans of Earth and Sea once more, not knowing if the consequences.
Upon being awakened, Rayquaza immediately flew to Sootopolis Mountain, modernly hollowed into a city and named Sootopolis City. This was where the Titans were clashing, much to the awe and fear of the local residents. Rayquaza repeated history and sent them back into their hidden caves, where they were to sleep peacefully forever more.
Rayquaza has since been captured and exact statistics on this respectable beast have been recorded in the Pocket Monsters Index, or the PokéDex.
Rayquaza measures in at a hight of 23 feet exactly, but only when sitting in a snake-like curl. Its long body from nose to tail has not yet been recorded, but is estimated to be about 60 feet or more. It weighs in at 455.2 lbs. It has the ability to pressurize the atmosphere around it, and nullifies all weather effects such as rain or intense sunrays. How it does this is yet to be explored. It is classified as Pokémon number 384 in the National PokéDex. It goes by the number of 200 amongst the Hoenn Region PokéDex. It has been dubbed the "Sky High Pokémon," for its ability to live in altitudes as high as the ozone layer.
A truely magnificent and rare beast indeed. There is only one in existance, but scientists in the Cinnibar Genetic Research Association are trying to clone it, so we may see more of this magnificent creature before the only one in existance dies.
