Known as a Monster Ball in Japan; a spherical capsule used to capture and store Pokémon (Pocket Monsters). The most common and recognized Poké Ball is the titular basic variant, which has two colored halves: red on top and white on bottom. It is one of the central symbols of the franchise.
Normally, captured Pokémon are shrunken down and stored inside the ball, though some refuse to go inside the Poké Balls. Ash's Pikachu is a notable example.
