Pokémon Red Version and Pokémon Blue Version are 1996 role-playing video games (RPGs) developed by Game Freak and published by Nintendo for the Game Boy. They are the first installments of the Pokémon video game series, and were first released in Japan as Pocket Monsters Red and Pocket Monsters Green, followed by the special edition Pocket Monsters Blue later that year. The games were released internationally in 1998 and 1999 as Pokémon Red and Pokémon Blue, while an enhanced version named Pokémon Yellow Version: Special Pikachu Edition, was released in Japan in 1998 and in other regions in 1999 and 2000.

The player controls the protagonist from an overhead perspective and navigates the fictional region of Kanto in a quest to master Pokémon battling. The goal is to become the champion of the Indigo League by defeating the eight Gym Leaders and the top Pokémon trainers in the land, the Elite Four. Another objective is to complete the Pokédex, an in-game encyclopedia, by obtaining all 151 Pokémon. Red and Blue use the Game Link Cable, which connects two Game Boy systems and allows Pokémon to be traded or battled between games. Both versions feature the same plot,[1] and while they can be played separately, players must trade between both games to obtain all of the original 151 Pokémon.
