Pokémon Gold Version, Silver Version, and Crystal Version - Tag Battles
In Stadium 2 (called "Pokémon Stadium Gold and Silver" in Japan and "Pokémon Stadium 2" elsewhere), two players can team up on a single side. Each player on a side enters six Pokémon, then chooses three of them before a battle begins. There are two variations of this so-called "tag battle":
- For the Anything Goes rules, each player on a side with two players can choose only a Pokémon he or she controls when it’s switched out or replaced with Baton Pass. Nevertheless, Whirlwind and Roar can replace the Pokémon on a side with another one controlled by either player on that side. If all Pokémon on a single side faint, that side loses.
- For other rules, each player on a side with two players can choose only a Pokémon controlled by the other player on that side when it’s switched out or replaced with Baton Pass. Nevertheless, Whirlwind and Roar can replace the Pokémon on either side with another one controlled by either player on that side. If all Pokémon controlled by even one of the players on a side faint, that side loses. (Because of this, the rules for Destiny Bond, Explosion, Perish Song, and Selfdestruct are applicable if one player on a side has only one Pokémon remaining.)
Things such as same-species and same-item restrictions are enforced only for each player’s team individually, not for the combined team when a battle begins.
