Poké Ball

Poké Ball refers to the device that can be used by trainers to catch and carry Pokémon with them. Although the concept of Poké Ball is rather complicated and hard to explain, they are very common in Pokémon world. Because Poké Balls never guarantee a capture, there are different kinds of them, such as Ultra Ball that is harder for wild Pokémon to resist. Trainers push on a button on the Poké Ball to change its size from smaller to bigger or vice versa. When a Poké Ball is thrown or particularly opened, the beams transfer Pokémon's data and bring them on the real world.
