Poké Ball

Poké Balls are important items originating from the Pokémon series; their purpose is to store and mobilize Pokémon within the ball when they're not in battle. They have appeared in all four installments of the Super Smash Bros. series as items. When thrown, the Poké Ball will release a random Pokémon out of the ball, say its cry, and attack. In Super Smash Bros. Brawl, the Pokémon Trainer uses a Poké Ball to change between his three different Pokémon: Charizard, Squirtle and Ivysaur.

The Poké Ball serves as the Pokémon series emblem. A trophy of a Poké Ball can be obtained in Super Smash Bros. Melee and Super Smash Bros. Brawl. Super Smash Bros. for Nintendo 3DS / Wii U introduced a new item, the Master Ball, which specifically releases only Legendary Pokémon, while the regular Poké Ball releases any non-Legendary Pokémon.

For a complete listing of Pokémon coming out of Poké Balls, see the Pokémon article.
