In the games

Since FireRed and LeafGreen Versions pairs of seemingly unrelated Trainers have been found at various points throughout the games and, if both see the player at the same time, will challenge them together. Other such battles happen at specific points in the game.

• In Emerald Version, Steven Stone battles two members of Team Magma alongside the player in the Mossdeep Space Center.
• Tag battles are also conducted in Hoenn's Battle Tower. Players have the option of teaming up with either computer-controlled partners or a friend via link cable.
• At various points throughout Diamond, Pearl, and Platinum Versions, five Trainers partner up with the player for a short time. As long as they are with the player, all wild battles will be conducted as double battles. Trainers in these areas are also set up to favor two-on-two tag battles. The same Trainers can later be selected to act as the player's partner in Sinnoh's Battle Tower.
• Professor Rowan's assistant and the player's rival will also team up with the player twice duing confrontations with Team Galactic.
• Battles at the Seven Stars Restaurant are all two-on-one tag battles
• In Platinum, the player and his/her rival are challenged to a tag battle by Flint and Volkner upon entering the Battle Zone for the first time.
