>>48856287Its true that they generally localize the names of Legendaries and Pikaclones to match the Japanese names, but that does not imply the Japanese pronunciation of Legendaries and Pikaclones takes precedence over spelling. Otherwise Kyogre would be pronounced Kyoga, Rayquaza as Rekkuza, and Emolga as Emonga.
>>48856300That's because the cries are based on the Japanese pronunciation. Same is true for Regigigas who says "Regigigasu" with the final "u." If you listen to the Pokedex 3D pronunciation of the name or the pronunciation used by the Pyramid King Brandon in the TPCi dub of the Anime (not the 4Kids dub), he clearly says Rej-ice.
