Pokémon FireRed and Pokémon LeafGreen are two Generation III video games. These are re-releases of the Japanese Pokémon Red and Green games.

The player embodies a young boy or girl determined to become a Pokémon master. Professor Chen offers him his 1st Pokémon of his choice so that he can obtain the 8 badges of the region, complete the Pokédex and defeat Team Rocket. The scenario is basically the same as in the Pokémon Red and Blue games. However, there are a few differences:

• After beating Pierre at Argenta, an assistant of Professor Chen gives the player the sports shoes.
• After defeating Auguste at Cramois'Île, Leo asks the player to come with him to the Sevii Islands to meet Professor Ciléo.
• The level of each member of Council 4 has decreased by 2 the first time the player fights them. Additionally, this Council 4 sees their Pokemon boosted by exactly 12 levels with a new Pokemon for each member (except for Aldo, as his two Onix evolved into Steelix) after the player completes the Sevii Islands quest.
• The events of Roc Nombri and Île Aurore are present.
• Blue only calls the player a loser when he first confronts him in Professor Chen's lab and during his encounter after the Council of 4.
• The music of the Powerhouse is that of the Pokémon Manor.
