A Poké Ball (sometimes spelled as Pokéball) is a round device used in the Pokémon series to catch and contain Pokémon. The Poké Ball also serves as a symbol for the series. There are many types of Poké Ball, such as the Great Ball or Ultra Ball. The invention of Poké Balls occurred in the Johto region, where Apricorns grow; these fruits were cut apart and carved out, then fitted with a special device, and used to catch wild Pokémon. Some Trainers still use Poké Balls made from Apricorns, while Kurt, a resident of Azalea Town, still constructs them. The Master Ball is the best ball in the game. It will capture any Pokemon with a 0% chance of failure, including Legendaries. You get the Master Ball from Professor Magnolia after completing the Pokemon League. You will only get one copy of this Pokeball in the game so use it wisely. According to official sources, though, Poké Balls as we know them were actually invented in 1925 by Professor Westwood. We meet him in the Season 1 episode “The Evolution Solution,” where he teaches our heroes about the unique way Slowpoke merges with Shellder to evolve into Slowbro.
