The Battle Trainer was an electronic toy made by Hasbro, released in 2005. It was a successor to the THINKChip Interactive System and utilized the THINKChip+ within Pokémon figures made for the game system.
The Battle Trainer system was initially packaged with a Pikachu figure. Other figures were sold individually. For the Pokémon 10th Anniversary, a bundle of the system and Pikachu and Groudon figures were sold exclusively at Target stores.
