Like all Mainstream Pokemon Games, there are a number of Pokemon you can receive as gifts throughout your journey in this game as well. The ninth Gift Pokemon you will have the chance to obtain is none other than Porygon. While attempting to defeat Team Rocket once and for all within the Silph Co Building found in Saffron City, you will come across a man that will mention how he fears Team Rocket might steal the Pokemon he personally developed. After defeating Team Rocket at Silph Co, you can find the man near the Saffron City Pokemon Center. He will then give you said Pokemon as a thank you gift for defeating Team Rocket, which is Porygon.
