Pokémon FireRed Version and LeafGreen Version are enhanced remakes of the original Pokémon Red and Blue video games, which were released in 1996.

Pokémon FireRed and LeafGreen takes place mostly in the fictional region of Kanto. This is one distinct region of many in the Pokémon world, which includes varied geographical habitats for the Pokémon species, human-populated towns and cities, and routes between locations. Some areas are only accessible once the player acquires a special item or one of the player’s Pokémon learns a special ability. Near the end of the plot, the protagonist is able to venture to the Sevii Islands, a new area not present in the original Red and Blue games. The Sevii Islands are an archipelago of seven islands and contain Pokémon normally exclusive to the Johto region, as well as several post-game missions. After the aforementioned missions on the Sevii Islands are completed, the ability to trade with Ruby and Sapphire for Hoenn-exclusive Pokémon becomes available.
