When a trainer (the player) encounters a wild Pokémon, he can capture it by throwing a spherical, mass-produced tool, called the Pokeball. All three goals are present in every version of the game and even in the expanded universe. The Trainers have three goals: collect the creatures known as Pokemon in a specific region, expand the national collection by adding the species collected from specific areas, and train a powerful team to conquer the region's best trainers (commonly known as the Elite Four). In the original Pokemon game, players are referred to as Trainers. He enjoyed collecting insects as a child and based the game from there.

Back in 1989, after the release of the Gameboy Console, Executive Director Satoshi Tajiri started building the game as we know it.
