Setting 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 players acquire a special item or one of their 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, based on the
Izu 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.
Story The
silent protagonist of
FireRed and
LeafGreen is a child who lives in a small town named Pallet Town in the Kanto Region. After players start a journey and venture alone into tall grass, a voice warns them to stop.
Professor Samuel Oak, a famous Pokémon researcher, explains to the player that such grass is often the habitat of wild Pokémon, and encountering them alone can be very dangerous. He takes the player to his laboratory, where they meet Oak's grandson, another aspiring
Pokémon Trainer. The player and their rival are both instructed to select a
Starter Pokémon for their travels. The rival then challenges them to a Pokémon battle with their newly obtained Pokémon and continues to battle the player at certain points throughout the games. After reaching the next city, the player is asked to deliver a parcel to Professor Oak. Upon returning to the laboratory, they are presented with a
Pokédex, a high-tech encyclopedia that records the entries of any Pokémon that are captured. Oak then asks the player to fulfill his dream of compiling a comprehensive list of every Pokémon in the game. While visiting the region's cities, the player encounters special establishments called
Pokémon Gyms. Inside these buildings are Gym Leaders, each of whom the player must defeat in a Gym battle to obtain a Gym Badge. Once a total of eight badges are acquired, the player is given permission to enter the Pokémon League in the Indigo Plateau, which consists of the best Pokémon Trainers in the Kanto Region. There the player battles the
Elite Four as well as the Pokémon League Champion: their rival. Also throughout the game, the player has to fight against the forces of
Team Rocket, a criminal organization that abuses Pokémon. They devise numerous plans to steal rare Pokémon, all of which the player must foil, meeting and defeating the criminal organization boss Giovanni. After the first time players defeat the Elite Four, one of the members, Lorelei, disappears. After gaining access to the Sevii Islands, an entirely new region, the player discovers Lorelei in her house and convinces her to come back with them. Once more, the protagonist must thwart Team Rocket's plans on several occasions, recover two artifacts, the Ruby and the Sapphire, and put them in the main computer at One Island. After that, the player can trade with
Ruby, Sapphire,
Emerald,
Colosseum, and
XD. ==Development==
