Pokémon Pikachu is a series of portable Pokémon virtual pets featuring the famous electric mouse Pokémon #25, Pikachu. This product was intended as an exercise toy and mentioned by Guinness World Records as the most popular fitness toy of its time.

There have been at least two releases of Pokémon Pikachu. The first is simply called Pokémon Pikachu, and the second is called Pokémon Pikachu 2 GS and can interact with Pokémon Gold, Silver, and Crystal via the Game Boy Color's Infrared Communication Port and Pokémon Gold, Silver, and Crystal's Mystery Gift option.

Both of the Pokémon Pikachu incarnations differ slightly from more traditional portable virtual pets in that Pikachu does not need to be fed, watered, or cleaned up after. Instead, the Pokémon Pikachu unit can be strapped to a belt and used as a pedometer. With every step it counts, the Pokémon Pikachu's Trainer earns "watts", which are used to buy the Pikachu presents and grow closer to it. Both Pokémon Pikachu incarnations feature the Pikachu doing different activities – more are earned as the Pikachu grows closer to its Trainer. Using the Mystery Gift feature from Pokémon Gold, Silver, and Crystal these watts could be used to generate items.
