Event 2: Master the Pokémon Tag Battle is a Co-Op Event Match in Super Smash Bros. Brawl. It involves playing as a Pokémon Trainer with 3 lives (like Event 5: Become the Champion!) and a Pikachu with 1 life (the second player) to defeat a Pikachu and a Pokémon Trainer. It takes place on Pokémon Stadium 2. An interesting note is that when one of the Pokémon Trainer's Pokémon is KO'd, they can not be used again (a possible reference to the anime and RPGs, where when one Pokémon has lost all it's HP and is unable to battle, that Pokémon cannot be used again.)
