Pokémon Stadium 2 (Pokémon Stadium Gold-Silver in Japan) is a video game for the Nintendo 64. It features all 251 Pokémon from the first and second generations. It was released in North America as simply Pokémon Stadium 2, as it was the second Stadium game to be released there. In Japan, Pokémon Stadium GS was the third game of the Pokémon Stadium series. The Japanese edition also featured the capability to use the Pokémon Mobile System from Pokémon Crystal.
This game featured support for all three original Game Boy Pokémon games (Pokémon Red and Blue and Pokémon Yellow) and the two Game Boy Color games (Pokémon Gold and Silver). As in Stadium 2/Stadium, Pikachu from the Yellow game was a hidden character if the game cartridge was used.
