Pokémon Yellow: Special Pikachu Edition, simply referred to as Pokémon Yellow, is the third installment in the international core series of Pokémon games and the fourth in the Japan releases. It was released for the Game Boy as the accompanying title for Pokémon Red Version and Pokémon Blue Version (or Pocket Monsters Red and Pocket Monsters Green and Pocket Monsters Blue in Japan).
Pokémon Yellow is very similar to its predecessors, using the same locations and sequences of them, however, Pokémon Yellow expands on the basis of the original pair to become more similar to Pokémon the Series. Pokémon Yellow is notable as it is the first of the series to allow Pokémon to walk alongside the player character, as well as having an Electric-type Pokémon being the starter Pokémon, as opposed to a Grass-type, Fire-type and Water-type.
Much like Ash Ketchum's adventures in the Kanto region, the player character begins the game with a Pikachu. After leaving home and walking to the grass where Oak would normally intercept you, you will instead be attacked by a wild Pikachu. Oak catches the Pikachu, and you get taken to the lab. Instead of getting the Eevee, your rival pushes you out of the way and gets Eevee, so Oak gives you Pikachu instead. Pikachu grows more fond of the character over time and refuses to return to its Poké Ball, and has frequent run-ins with Jessie, James and Meowth. Additionally, the starter Pokémon of the original pair, Bulbasaur, Charmander and Squirtle, can all be found in-game. Charmander is received from a poor trainer in the areas north of Nugget Bridge in Cerulean City; Bulbasaur is received from nurses in Cerulean City and Squirtle is received from Officer Jenny after defeating Lt. Surge in the Vermilion City Gym.

Trivia
- Pokémon Yellow is the first game in the series to have only one starter Pokémon, a feature that would not be reused until Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee!, which themselves are remakes of Yellow.
- Pokémon Yellow and one of its remakes Pokémon: Let's Go, Pikachu! are the only Pokémon version games to have a pure Electric-type Pokémon as the version mascot.
- Pokémon Yellow is the only game to have a starter Pokémon that needs an Evolutionary Stone to evolve, although Pikachu cannot do it in Pokémon Yellow.
- It is impossible to fully complete the Pokédex without using the Mew Glitch.
- The gym leaders' Pokémon's levels in Pokémon Yellow are generally higher than those in Pokémon Red Version and Pokémon Blue Version.
- Pokémon Yellow is the first game to feature the player's starter following the player character.
- Pokémon Yellow is the only game where Pikachu won't evolve, the only way to make it evolve is to trade it, evolve it, then send it back to Yellow.
- During the game, the player is able to obtain Bulbasaur, Charmander, and Squirtle in different locations as Pikachu takes their place as a Starter Pokémon.
- It is the first game to have color in it, despite the software being released for the original Game Boy and not Game Boy Color.
