Poke Balls

A Poké Ball (Japanese: モンスターボール Monster Ball) is a type of item that is critical to a Trainer's quest, used for catching and storing Pokémon. Both a general term used to describe the various kinds as well as a specific term to refer to the most basic among these variations, Poké Balls are ubiquitous in the modern Pokémon world. Up to six Pokémon can be carried with a Trainer in Poké Balls, while any number of other Poké Balls can be held in the Bag for later use. These six Pokémon in the Poké Balls can be attached to the user's belt for carrying them around. Some Pokémon do not like to be carried around in Poké Balls, such as Ash's Pikachu.

The strength of a Poké Ball is determined by how much it raises a wild Pokémon's catch rate, and may in fact vary depending on the conditions of the battle. Poké Balls limit the power of Pokémon contained inside, taming them, though they do not cause the Pokémon inside to always obey the Trainer.

Stylized Poké Balls are used in many places to symbolize Pokémon in general: the logos of all three Battle Frontiers feature a Poké Ball in their design, while several Poké Balls can be seen in every Pokémon Center. The headgear of the protagonists of Kanto, Hoenn, Sinnoh, and Unova-based games feature Poké Ball designs, as do the Bags of the protagonists of Johto-based games. Ethan's headgear is also similar to the top half of an Ultra Ball, and Lucas's Bag prominently features a Poké Ball.
