Masuda method: Difference between revisions

added additional reference pointing out that the behavior has always been to treat them as properly foreign in Gen 4, also fixed link to Pokémon Language page.
(→‎Usage: Information about ingame trades not counting as foreign language Pokémon is completely false, and unless behavior differed in older generations, this is myth that's been spread around for over a decade. The language of origin tag is the only value used to determine whether Masuda Method applies, there is no hidden blacklist or data that differentiates a foreign NPC trade Pokémon from one actually obtained from a foreign savefile via trade.)

The Masuda method involves breeding two Pokémon created in games of different languages. An Egg resulting from such a pairing will have a higher likelihood of being Shiny. The most common way to arrange such a pairing is to use one foreign Pokémon and one from the game in which the breeding occurs, although the method will work in any game or combination of languages provided at least one of the Pokémon in the pair is from a language different to the language of the other parent. The language of the game does not have any affect on whether Masuda Method applies, only the languages of the two parents are taken into account.

If both Pokémon are foreign to the language the game is being played in but are both of the same language, then the Masuda method will not take effect. Despite being obtainable in one's native language savefile, foreign language Pokémon obtained via [[in-game trade]]s, such as the {{DL|Foreign Pokédex entries|In Generation IV|Meister}}'s {{p|Magikarp|Foppa}} and [[Lt. Surge]]'s {{p|Pikachu|Volty}}, are treated as being from the language of origin shown by the language tag,<ref>https://twitter.com/Sibuna_Switch/status/1558955387369439232</ref> so if bred with a parent with a different<ref>https://twitter.com/Sibuna_Switch/status/1558956869829492737</ref> language of origin, the Masuda method will take effect.

In Generation IV only, if the Masuda method applies, the [[Everstone]] will fail to increase the chance of passing on a Nature. This is due to Nature and Shininess both being determined by the Pokémon's [[personality value]] in Generation IV, so manipulating one would interfere with the other. From Generation V onward, Nature is not determined by personality value, so this restriction is removed.

From [[Generation III]] onward, Pokémon track their [[language of origin]], identifying the language of the game they were originally obtained in. From Generation IV onward, if the two Pokémon in the Day Care have different languages of origin, when an Egg is generated, the game will generate extra [[personality value]]s in an attempt to find one that results in a Shiny Pokémon for the player. This stacks with the [[Shiny Charm]]'s effect, which works in the same way.

The number of rerolls differs between games. Because the rerolls are in addition to the standard roll, the total number of rolls is one higher than the number of rerolls. The probability of hatching a Shiny Pokémon is approximately equal to the normal Shiny rate multiplied by the total number of rolls (i.e. one more than the number of rerolls). The Shiny Charm also adds rerolls in the same way, so its effect can be combined with the Masuda method.
