A ball that can capture and hold a Pokémon, there are various types that have various special abilities.
A Poké Ball is a device used to capture Pokémon. Poké Balls are usually issued to a Pokémon Trainer after receiving his or her first Pokémon, after running out a trainer must purchase more from a Poké Mart. A Poké Ball cannot catch the Pokémon of another trainer unless hooked up to a snag machine.
Though the technology behind a Poké Ball remains unknown, the basic mechanics are simple enough to understand: in a Pokémon battle, once an opposing wild Pokémon has been weakened, a person, the Pokémon Trainer, can throw a Poké Ball at it. If the Poké Ball hits the Pokémon and is not knocked back by it, the Poké Ball will open, convert the Pokémon to a form of energy, and pull it into its center, closing. A Pokémon in this state is given a chance to struggle to attempt to escape, at which point the ball will either be destroyed (in the games and some manga) or will return to the Trainer (anime), who can attempt once again to capture the Pokémon. A Pokémon who does not escape the ball will be caught.
Some Pokémon, a prime example being Ash's Pikachu, refuse to return to their Poké Ball, be it out of dislike or fear. In other cases, some Pokémon refuse to come out of their Poké Balls.
