 These Pokémon are usually placed at the end of their respective games' Pokédex and can only be obtained through distribution events set up by Nintendo.The first of these Mythical Pokémon was Mew, who was programmed into the "Red" and "Green" games as a secret character by Shigeki Morimoto without any knowledge of the other members of the development team, and was not announced until several months after the games' release in a special promotion.Since then, the games have continued to feature Pokémon that cannot be obtained through standard gameplay, but the programming that allow the player to catch them within the games can be activated by special items (or other Pokémon) distributed by Nintendo.
