Pokémon Red, Green, Blue & Yellow Version Differences
Compare release history, version roles, starters, encounters, sprites, and gameplay changes.
This comparison separates Japanese Red/Green, Japanese Blue, international Red/Blue, and Yellow so Green is represented accurately without pretending it was an international English release.
| Category | Red | Green | Blue | Yellow |
|---|---|---|---|---|
| Release role | Original Japanese pair member and international launch version name. | Japan-only original pair member; not released internationally as Pokémon Green. | Japanese enhanced release; international Red/Blue were based largely on this improved version. | Anime-inspired Special Pikachu Edition released after the original versions. |
| Starter structure | Choose Bulbasaur, Charmander, or Squirtle. | Choose Bulbasaur, Charmander, or Squirtle. | Choose Bulbasaur, Charmander, or Squirtle. | Pikachu is the fixed starter; Bulbasaur, Charmander, and Squirtle are gifts. |
| Version availability | Red-side exclusives such as Ekans, Oddish, Mankey, Growlithe, Scyther, and Electabuzz. | Green-side exclusives broadly align with the counterpart role to Japanese Red, including Vulpix, Meowth, Bellsprout, Pinsir, and Magmar lines. | International Blue uses Blue-side counterpart exclusives; Japanese Blue has its own adjusted encounter context. | Several encounters and gift Pokémon differ, and completion still requires trading. |
| Presentation | Original Gen I structure; international Red reflects the improved release base. | Original Japanese sprites and early-release quirks are a key historical distinction. | Japanese Blue improved presentation and content details before the international releases. | Updated sprites, Pikachu following behavior, and anime-inspired character appearances. |
Japanese Blue was a revised Japanese release after Red/Green. International Pokémon Blue shares much of that improved foundation, but it is not simply the same release with English text.
Original Japanese Red/Green, Japanese Blue, and international Red/Blue need separate treatment for historical notes and route-level data.
