Set Details
Gear up for battle with the Gym Heroes™ expansion!
Every Pokémon trainer has a unique philosophy on how to best prepare Pokémon for battle. In the Gym Heroes expansion, some of the world’s best Pokémon gym leaders have specially trained their Pokémon to create an all-new trading card game adventure. Team up with Misty, Brock, Lt. Surge, and Erika, and become a gym hero!
The Gym Heroes Pokémon Set stormed into the TCG scene as the sixth main expansion in English (released August 14, 2000) and the fifth in Japan (released October 24, 1998, as Leaders’ Stadium). Drawing inspiration from Pokémon Red, Blue, and Green, the 132‑card English set spotlights the Kanto Gym Leaders—Brock, Misty, Lt. Surge, and Erika—letting players battle with Pokémon that proudly bear their Trainers’ names. Thanks to its vibrant trainer portraits and badge icons, the Gym Heroes Pokémon Set instantly stood out on store shelves and provided a fresh, character-driven twist to the game.
What truly made the Gym Heroes Pokémon Set revolutionary was its debut of Owner’s Pokémon—cards like Brock’s Onix or Lt. Surge’s Pikachu, displaying a head-shot of the Gym Leader in the bottom-right corner. This mechanic subtly altered the card layout: the Retreat Cost shifted beneath Weakness/Resistance, and the familiar Pokédex entry disappeared to make room for the Trainer portrait. The expansion also introduced the very first Stadium cards, a new subclass of Trainers that changed the battlefield for both players until another Stadium replaced it. In Japan, Leaders’ Stadium launched alongside pre-constructed theme decks, kick-starting the tradition of ready-to-play Gym Leader decks well before they hit international markets.
A few fascinating tidbits keep collectors buzzing about the Gym Heroes Pokémon Set. Early English 1st Edition packs occasionally show slightly darker ink saturation, creating a subtle printing variant prized by grading purists. The set symbol itself differs between languages—another first for the Pokémon TCG. And then there’s Sabrina’s Gaze: the original Japanese artwork showed Sabrina casually holding a Master Ball, but the English release redrew the scene after censors felt her raised finger looked a little too suggestive. Adding to its rich backstory, the Gym Heroes Pokémon Set also merged cards from Japan’s Challenge from the Darkness (Gym 2) to flesh out its roster, creating an expansion loaded with quirky history and collectible nuances that continue to captivate TCG enthusiasts.
