Pokémon Green is a role-playing video games developed by Game Freak and published by Nintendo for the handheld Game Boy. It was first released in Japan on February 27, 1996 and is the first video game in the Pokémon series of games, together with Pokémon Red. In the west, Pokémon Green was updated to Pokémon Blue.
Developed over the course of several years, Red and Green established several standards for later Pokémon games and sequels. They take place in the Kanto region, with the player having to collect eight Gym Badges to become the Pokémon Champion while also completing the Pokédex by collecting all 151 Pokémon. The game was a commercial success in Japan, which prompted the localization of Red and Green for an international release; the games were then released as Pokémon Red and Pokémon Blue.
In 1999, the sequels to these games, Pokémon Gold and Silver, were released for the Game Boy Color. In 2004, Red and Green were remade for the Game Boy Advance as Pokémon FireRed and LeafGreen.
