Latin name: Golema germanicus pedrus
According to Celtic archaeological studies, Regirock was the result of the assembly or rocks and boulders gathered from all over Norway and Sweden and deliberate infestation of Gastly and Haunter to create a golem that would invariably respond to the whim of the Norse king.
The British Library estimates that the creation of Regirock began in the 600s B.C. and ended in 401 B.C., after several times giving up on the project. Regirock was the first artificial golem to be created and served the longest in Germanic war fronts; Regice was to follow in 287 B.C., and Registeel was created by the Romans in 41 A.D. under the direction of Emperor Augustus Cæsar and given to the Germanics as a peace offering. Regice was gathered from ice from the islands of Norway near what is now Tromsø, and Registeel was created from metals imported from the Babylonians, although it was once believed that Registeel was made of extraterrestrial metals.
Although Regirock originally had a tail, this was destroyed in 434 A.D., when the Visigoths stole Regirock and used it to destroy Roman outposts in Spain. It is said that this tail is a component of the high elevations of the Spanish Extremadura. In 509 A.D., Regirock was returned to the Celtics, but by then it had become so accustomed to the Visigoths that it rebelled, compelling the Celtics to restrain it and bury it under a huge boulder in Sweden. About one hundred years later Regice and Registeel went the same way.
The three golems were entombed in those monoliths in Sweden until 1716, when it was first reported that the monoliths had gone missing. The monoliths were found again in 1859 in Hoenn, which had just been conquered by the British. In 1874 a blind geologist went to study the ruins, ostensibly to figure out how the monoliths were moved, and died mysteriously, but not before engraving Braille inscriptions for his references. It wasn't until 1985 that the tombs were found again, and the scientist's body was discovered under a boulder near Regice's abode. In 1991 Regirock was unearthed and found to be alive, and now it is protected under the Seakoum Act of 1997, which prohibits capture of the golems. Its definition for the Cryptozoology Advisory Board was drafted and finalised in November 2001 after a six-month research project.
