Pocket Monsters Blue (Japanese: ポケットモンスター 青) was the third Pokémon game released in Japan on October 10, 1996, as a minor revision of Red and Green, which were released earlier that year. It was thus the first third version of Pokémon, and was initially sold only to subscribers to CoroCoro.
Various fixes in the game include a graphics and sound upgrade, as well as the removal of several known glitches that had been found in the original pair. Like its paired predecessors, it was never truly released outside of Japan, however, while Red and Green provided the wild Pokémon and version-exclusive lists for the rest of the world’s Red and Blue, Blue provided the graphics, game engine, and script for translation.
Changes from Red and Green
- Kanto is slightly redesigned, with the design of doors, signposts and other elements changed.Cerulean Cave, the game’s final dungeon, receives the most significant overhaul, sporting a different layout. These designs would later be reused for the internationalPokémon Red and Blue.
- Interestingly, theIndigo Plateauwas the only place in Kanto duringGeneration Ithat remained the same in all of the four games.
- In-game tradesare changed to different Pokémon.
- Game Cornerprizes are different.
- The introduction of the game features a battle between aGengarand aJigglypuff, as opposed to a Gengarand aNidorino, as it was inPokémon Red and Green. This change carried on into the localized version of Pokémon Blue, while the original appeared in the localized Pokémon Red.
- Pokémon only available through an in-game trade in Red and Green are now found in the wild.
- Missingno.was given the placeholder Pokédex entry 「コメント さくせいちゅう」 “Comment to be written.” and became the ??? species. This was not translated, resulting in a glitched Pokédex entry in the localizedPokémon Red and Blueand the corruption of Missingno.’s original height and weight (1.0 mand10.0 kgrespectively), showing instead a height of10.0 ftand a weight of3507.2 lb.
Because the script for Pokémon Blue, rather than that of Pokémon Red and Green, was used for the translation of the Japanese trio into Pokémon Red and Blue, an old man who trades the player an Electrode on Cinnabar Island claims that the Raichu he received “went and evolved”. As Raichu does not have an evolved form, this makes no sense whatsoever. In the context of Pokémon Blue, however, it makes sense, as the player trades away a Kadabra, which evolves through trade, for a Graveler in this game.
Pokémon Blue, as well as its older, paired counterparts, are the only Generation I games that don’t provide a waiting message when the saving process is in course.
