The narrator usually speaks at the beginning and ending of each episode. In the beginning of an episode he usually informs the audience of what Satoshi and his friends are doing or where they're heading. Sometimes he'll even explain what they did in the previous episode. He would usually conclude the episode with what Satoshi and company had learned during the episode or say what they were planning to do next. In movies, he usually is only heard at the beginning giving an overview of the Pokémon world.
