A trainer class in the Pokémon media.
Gym Leaders are the heads of the Pokémon Gyms, facilities where Pokémon, typically of a specific type, are trained to battle with participants of the Pokémon League challenge. As part of the Pokémon League, each Gym has an official Badge, most often obtained by winning a battle against the Gym Leader. A Gym may have more than one Leader, and the Leaders' roles in their community often extend beyond their Gym.
