Silph Co.

Silph Co. is a fictional company located in Saffron City dedicated to creating tools related to Pokémon, especially for Pokémon trainers. Objects created by Silph include the Pokémon Porygon, the Up-Grade (to evolve Porygon to Porygon2), Master Balls, and TMs and HMs. In order to access most of the city, the player must liberate Silph Co. from the control of Team Rocket. Silph Co. is a very elaborate location that utilizes teleport pads to warp the player from location to location. Team Rocket grunts and scientists are scattered around the place, making it more difficult to move around. At the top floor, Giovanni is waiting. After the player defeats him, he disappears along with all the other members of Team Rocket.

In Gold, Silver, and Crystal, Silph Co. has improved security and the player can no longer see the top floors. Saffron also houses the Magnet Train, which runs between Saffron and Goldenrod City in the Johto region. Also, the player can no longer battle in the Fighting Dojo, as Master Kiyo has left for Johto.

In Super Smash Bros., Saffron City is a playable stage, housing Silph Co. and other two buildings.
