Pokémon Blue Version is a game in the Pokémon series that was released alongside Pokémon Red in 1996 for the Game Boy, specifically in certain regions like Japan. This game is well-known as a version that features similar gameplay to Pokémon Red but includes some different Pokémon and details. Like Pokémon Red, players take on the role of a Trainer who must explore the Kanto region, catch Pokémon, and battle other Trainers to become a Pokémon Master. Pokémon Blue features certain Pokémon that cannot be caught in Red, such as Ekans and Arbok, while some Pokémon exclusive to Red are not available in Blue. The game utilizes a turn-based battle system similar to Red, allowing players to choose Pokémon and attacks to defeat opponents.
