Gym Challenge is the name given to the seventh main expansion of the Pokémon Trading Card Game. In Japan, it was released as Challenge from the Darkness, the sixth expansion in the Pokémon Card Game. It is based on Pokémon Red, Blue, and Green, featuring Generation I Pokémon and the Kanto region's Gym Leaders. The English expansion was released on October 16, 2000, while the Japanese expansion was released on June 25, 1999. Gym Challenge combines its Japanese equivalent with the Leaders' Stadium expansion.
Two cards feature different illustration in the English release and the Japanese release as they were deemed "inappropriate". Koga's Ninja Trick originally has a swastika that resembled the swastika used by the Nazis, and it was changed to a different symbol. Misty's Tears originally has Misty drawn nude, and it was changed to a Squirtle trying to stop Misty's tears from falling down.
The Challenge from the Darkness set is released in Japanese, all with rarity symbols. Some cards without rarity symbols are available in Japanese gym theme decks. The Gym Challenge set is only released in English, in both 1st and unlimited edition.
