Foreign Pokédex entries are a feature introduced in Pokémon Diamond and Pearl, the first Pokémon games to officially support trading between languages. Originally limited to a select group of Pokémon, multilingual Pokédex entries are now accessible for every Pokémon in nine different languages.
The Meister (Japanese: マイスターMeister) is a character in Pokémon Diamond, Pearl, and Platinum who upgrades the player's Pokédex with the ability to store entries in foreign languages. He lives in a small house on an island on Route 226. His sprite is the same as the Hiker Trainer class.
After he upgrades a player's Pokédex, he offers to trade the player a German Magikarp in exchange for a Finneon. This adds Magikarp's German entry to the player's Pokédex.
In the German-language versions of the games, the Meister will trade an English Magikarp. His name in these games is English in origin: The Master.
Diamond and Pearl
In Diamond and Pearl, fourteen Pokémon can have foreign Pokédex entries registered. The entries come from either the FireRed or LeafGreen version of the language in question when said Pokémon is received from a foreign game.
The more healthy the Roselia, the more pleasant its flowers' aroma. Its scent deeply relaxes people.
はなの かおりを かぐと きもちが リラックスする。
かおりの つよい ロゼリアは げんきな しょうこ。
Its flowers give off a relaxing fragrance. The stronger its aroma, the healthier the Roselia is.
Ses fleurs dégagent un parfum relaxant. Plus fort est cet arôme, et plus Roselia est en bonne santé.
Seine Blüte verströmt einen entspannenden Duft. Je stärker dieser Duft ist, desto gesünder ist Roselia.
Las flores que tiene desprenden un aroma relajante. Cuando más intenso, mejor es el estado de salud de Roselia.
I bellissimi fiori sulle sue braccia possiedono spine velenose. Non cercare di raccoglierli!
In Pokémon Platinum, the Meister's upgrade instead allows the player to record foreign Pokédex entries for all 493 Pokémon. These entries are the ones used in that language's version of Diamond.
HeartGold and SoulSilver
In Pokémon HeartGold and SoulSilver, the foreign Pokédex entries are the same as in Platinum. Unlike the previous games, the ability to collect foreign Pokédex entries is available from the start.
In Black, White, Black 2, and White 2, the foreign Pokédex entries are also the same as in Platinum, just like native entries. However, only non-Unova Pokémon receive foreign Pokédex entries. For Black and White this is likely because foreign entries and names of Unova Pokémon had not been finalized yet at the time of the Japanese release of Black and White. However it is unknown why they were not included for Black 2 and White 2 as foreign Pokédex entries for Unova Pokémon would have been available from international releases of Black and White. The player is now able to collect Korean entries.
Generation VI onward
Every Pokémon now has collectible foreign entries in all seven of the game's languages, due to the simultaneous international release.
Generation VII onward
The player can now collect entries in nine languages, as the games were also released in Traditional Chinese and Simplified Chinese.
In Pokémon Brilliant Diamond and Shining Pearl, the Meister will attempt to upgrade the player's Pokédex, only to note that it has already been upgraded with the foreign Pokédex entry feature. He then proceeds to offer his in-game trade as usual.
A GTS event in 2007 involved foreign Pokémon, allowing players to trade an American Ponyta for a Japanese Psyduck and a Japanese Roselia for an American Heracross.
