Poké Ball

 are items in the Super Smash Bros. series from the Pokémon series that when thrown, will release a random Pokémon out of the ball, say its cry, and attack. Very, very rarely, the player will encounter a Pokémon such as Mew, Jirachi or Celebi. These Pokémon don't do any damage to anybody, they just fly off screen and drop items. However, after the battle, the player will get a huge score for seeing that Pokémon. The Pokéball returns in Super Smash Bros. Brawl. The Pokémon Trainer uses a Pokéball to change between his 3 different Pokémon.

The Poké Ball is also the Pokemon series emblem.

A trophy of a Pokéball can also be obtained in Super Smash Bros. Melee and Super Smash Bros. Brawl

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