Pokémon Battle-e were e-Reader card sets that was made to be used with Pokémon Ruby and Sapphire, and later Pokémon Colosseum, Pokémon FireRed and LeafGreen, and Pokémon Emerald. The later sets were not released in America. When connected with the game, the player could receive extras such as new berries, and new trainers to battle.

Oddly, the Pokémon you battled through the trainer cards would not give your Pokémon any experience points or items after they were completed. When the player scans a berry card, you'll receive a berry from a character.
