Gym Leaders have been part of the Pokemon TCG's identity since almost the very beginning, with two entire expansions built around them.
Gym Heroes and Gym Challenge
Released in 2000, Gym Heroes and Gym Challenge split Kanto's eight Gym Leaders across two sets, pairing each one's signature Pokemon with cards bearing their name and likeness - an early example of the game leaning into its own cast of characters rather than just Pokemon.
A template for character-driven cards
The Trainers Pokemon format used in the Gym sets, where a Pokemon card is explicitly tied to a named character, set a pattern that later Supporter and character cards would follow in spirit, even as the exact mechanics evolved.
Gym Leaders beyond Kanto
As the games expanded into new regions, later sets picked up the same idea for their own Gym Leaders, giving collectors themed cards for regional favourites well beyond the original eight.
