Gym Heroes is the name given to the sixth main expansion of the Pokémon Trading Card Game. In Japan, it was released as Leaders' Stadium, the fifth 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 August 14, 2000, while the Japanese expansion was released on October 24, 1998. Gym Heroes combines its Japanese equivalent with the Challenge from the Darkness expansion.
Gym Heroes introduced Owner's Pokémon, a Pokémon that has a Trainer's name. A headshot of its Trainer was located on the bottom right corner of the card with their Gym Badge in the background. The Retreat Cost was moved below the Weakness and Resistance and it lacked the Pokédex entry. It also introduced the Stadium card subclass of Trainer cards.
Leaders' Stadium was the first Japanese expansion to feature pre-constructed Theme Decks. This was the first expansion to feature different set symbols for its English and Japanese releases.
Sabrina's Gaze features different illustration in the English release and the Japanese release. It originally has Sabrina drawn holding a Master Ball, however her middle finger seems to be protruding upwards, and it was changed to Sabrina throwing a Poké Ball.
