In each region there is a Pokemon Professor. They usually appear at the very beginning of the game, giving the player an introduction to the Pokemon world. When the game begins, they will usually give a starter Pokemon to you after you have completed a specific task with one of the three starters. They also give the player a Pokedex with the hope that they will record data on every Pokemon of that region. The professors usually live in the same town as the player character, with the exception of Prof. Rowan, who lives in a nearby town.
