Pokémon Blue Version (Japanese: ポケットモンスター 青 Pocket Monsters: Blue) is the third core series Pokémon game for Game Boy, released in Japan on October 15, 1996 exclusively to subscribers of Comic CoroCoro Comic[1][2] and on October 10, 1999 to general retail[1][2] as a minor revision of Pokémon Red and Green Versions, which were released earlier that year. It was thus the first solitary version in the core series Pokémon games.

On November 12, 2015, a Nintendo Direct announced that Blue will be released in Japan on February 27, 2016, the Pokémon 20th Anniversary, for the Nintendo 3DS Virtual Console.

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.

Outside of Japan, its graphics, game engine, and script formed the basis of Pokémon Red and Blue, while the wild Pokémon and game-exclusive Pokémon lists were changed to match Red and Green.


201 SPOILER WARNING - this article may contain major plot or ending details.
Proceed at your own risk!

Much as would become standard for solitary versions, players follow the plot of the previous two games. Like in Red and Green, the player starts 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.

Once more, the eight Gym Leaders of Kanto are Brock, Misty, Lt. Surge, Erika, Koga, Sabrina, Blaine, and Giovanni, while the Elite Four are Lorelei, Bruno, Agatha, and Lance, with the rival still in the Champion's place.

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 aesthetically redesigned, with the design of doors, signposts and other tilesets redesigned. Cerulean Cave, the game's final dungeon, receives the most significant overhaul, sporting a completely different layout. These designs would later be reused for the international Pokémon Red and Blue. Indigo Plateau remains unaltered.
  • All Pokémon have new front sprites but retain the same back sprites from Red and Green. Trainers and the literal Ghost have the same sprites from Red and Green. The sprites from Blue would later be used in the international Pokémon Red and Blue.
  • Pokémon have new Pokédex entries.
  • In-game trades are changed to different Pokémon.
  • Game Corner prizes and slot machine icons 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.
  • The places where some Pokémon are obtainable was changed:
  • A small number of glitches were fixed:
    • A glitch that allows the player to surf from the top of a cliff was removed.
    • A glitch where the game mistakenly believes the player has beaten Sabrina (when they actually lost to her) was removed.
  • 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 (3.3 ft) and 10.0 kg (22.1 lb), respectively), showing instead a height of 10.0 ft (3.1 m) and a weight of 3507.2 lb (1590.8 kg).[3]

Similar to 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).

Elite Four

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.

Missing Pokémon

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 from Generation II. The table below indicates which paired Generation I game has that Pokémon available.

Note that G marks the Pokémon obtainable in Pokémon Green, which has the same available Pokémon as Western Blue.

023 023 Ekans Poison R
024 024 Arbok Poison R
037 037 Vulpix Fire GY
038 038 Ninetales Fire GY
056 056 Mankey Fighting RY
057 057 Primeape Fighting RY
069 069 Bellsprout Grass Poison GY

Players may trade Pokémon between two cartridges or battle with another cartridge using a Game Boy Game Link Cable. To take full advantage of this feature, several Pokémon are exclusive to other Generation I games and others require trading to evolve, making trading necessary to complete the Pokédex. The game can trade and battle with Japanese versions of Pokémon Red, Green, Blue and Pokémon Yellow. It can also trade with Japanese versions of Template:Game2 via the Time Capsule. Pokémon Blue is completely incompatible with games from Generation III onward.

Trades between Pokémon games in different languages are possible; however, a Japanese game cannot connect with a non-Japanese game without causing corruption. This is due to the fact that the games cannot automatically translate the Pokémon data from Japanese to a different language or vice versa, since neither game fully encodes both kana and the alphabet Latin alphabet (only encoding one fully and the other partially). If a battle between a Japanese game and a non-Japanese game is attempted, the battle simply does not work, with the save files left unharmed.

Pokémon Blue is compatible with Pokémon Stadium, Pokémon Stadium 2 (released as Pokémon Stadium in English), and Pokémon Stadium Gold and Silver (released as Pokémon Stadium 2 in English). While link battles are not possible directly between Pokémon Blue and the Generation II games, a player may challenge a Generation II game using Pokémon Stadium Gold and Silver.

Virtual Console

The Nintendo 3DS Virtual Console release uses 3DS wireless communication as a substitute for the Game Link Cable. Japanese and non-Japanese Generation I core series games do not recognize each other when attempting to link them via 3DS wireless communication.

Using Poké Transporter, the entirety of Box 1 can be sent from the Generation I core series games to Pokémon Bank (regardless of language), from where they can be withdrawn in the Generation VII core series games.

Differences in the Virtual Console release

The Nintendo 3DS Virtual Console release can link with other Virtual Console Generation I and II core series games via Nintendo 3DS wireless communication, simulating the Game Link Cable. When initiating a link, the Virtual Console menu on the touch screen replaces the Cable Club attendant's dialogue.

Using Poké Transporter, Pokémon can be sent from the Generation I core series games to Pokémon Bank, from which they can be withdrawn in the Generation VII core series games.

The moves Blizzard, BubbleBeam, Confusion, Dream Eater, Explosion, Guillotine, Hyper Beam, Mega Kick, Mega Punch, Psychic, Reflect, Rock Slide, Selfdestruct, Spore, and Thunderbolt had their animations changed slightly to tone down the flashing.

An error made during development causes the Pokémon depicted during Professor Oak's introductory lecture to be a Nidorino but with the cry of a Nidorina. This was already the case in the Japanese Red and Green and it was not fixed in Red and Blue.

  • Because Pokémon Red and Blue use a translation of the script of Pokémon Blue but use the in-game trades from Pokémon Red and Green, two translation errors related to these trades occur.
    • The 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 is not possible. However, in the context of Japanese Pokémon Blue, it makes sense as the player trades away a Kadabra, which evolves through trade, for a Graveler.
    • The old man who trades the player a Jynx in Cerulean City claims that the Poliwhirl he received "went and evolved". As Poliwhirl cannot evolve via trade in Generation I, this is not possible. However, in the context of Japanese Pokémon Blue, the old man trades away a Haunter for a Machoke, which does evolve through trade.
