Pocket Monsters: Blue (Japanese: ポケットモンスター 青) is the third main series Pokémon game for Game Boy, released in Japan on October 10, 1996 as a minor revision of Pocket Monsters: Red & Green (Japanese: ポケットモンスター 赤・緑), which were released earlier that year. It was thus the first third version in the main series Pokémon games, and was initially sold exclusively to subscribers of CoroCoro Comic.
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 Pokémon lists for the rest of the world's Pokémon Red and Blue, Blue provided the graphics, game engine, and script for translation.
Much as would become standard for third versions, players followed the plot of the previous two games. Like in Red and Green, they started in Pallet Town in the Kanto region, receiving a starter Pokémon from Professor Oak. As before, the choices are Bulbasaur, Charmander, and Squirtle, and the rival chooses the starter that is super-effective against the player's starter.
Again, the evil Team Rocket is causing chaos across the region, and it is up to the player to defeat them.
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 international Pokémon Red and Blue.
- In-game trades are changed to different Pokémon.
- Game Corner prizes are different.
- The introduction of the game features a battle between a Gengar and a Jigglypuff, as opposed to a Gengar and a Nidorino, as it was in Pokémon 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 localized Pokémon Red and Blue and the corruption of Missingno.'s original height and weight (1.0 m and 10.0 kg respectively), showing instead a height of 10.0 ft and a weight of 3507.2 lb.
Much as in Red and Green, there are eight Pokémon Gyms in Kanto, each with their own type affiliation. The Gym Leaders are Brock (Rock), Misty (Water), Lt. Surge (Electric), Erika (Grass), Koga (Poison), Sabrina (Psychic), Blaine (Fire), and Giovanni (Ground).
The Elite Four at Indigo Plateau also remains unchanged, with Lorelei (Ice), Bruno (Fighting), Agatha (Ghost), and Lance (Dragon). The Champion is Blue, who has no type specialization.
Blue did not introduce any new Pokémon, and so the 151 present in Red and Green are the only ones obtainable. Like Red and Green, some Pokémon are missing from Blue and must be traded from another game to complete the Pokédex or evolved from less powerful forms.
The following Pokémon are not obtainable in Pokémon Blue. In order to obtain any of the below Pokémon, they must be traded from one of the paired versions of Generation I, or Generation II, which has that Pokémon available, which will be indicated.

The soundtrack contains all of the background music and sound effects used in Pokémon Red and Green (the basis for the soundtrack of the Japanese Pokémon Blue), all of which were composed solely by Junichi Masuda. This includes Pokémon cries and Pokédex entries read by "Dexter", Ash's Pokédex.

The game, like its predecessors (Pokémon Red and Green), had many beta elements prior to its release, although Pokémon Red and Blue would later have several altered aspects of their own during the two-and-a-half years between the release of Red and Green, their bug-fixing release, Blue Version (Japanese), and the release of the merger between the Japanese games into Red and Blue for overseas markets.
- 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.
- The same issue arises with the old man that trades the player a Jynx in Cerulean City who claims that the Poliwhirl he received "went and evolved". While Poliwhirl does evolve, it does not evolve by a trade but rather through the use of a Water Stone. This issue is likely because in Pokémon Blue, the old man trades away a Haunter for a Machoke which does evolves through trade and the original script was not edited.
- 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.
- Unlike Red and Green, however, it doesn't inform the player that the saving process will overwrite the previous save file, a situation that carried over into the English versions.
- The Pokémon depicted during Professor Oak's introductory lecture is a Nidorino. However, the cry that plays belongs to Nidorina. This is actually a mistake that was carried over from Red and Green. The issue also remained in the localizations.
