Here is how to find Porygon, Porygon2 and Porygon-Z, or simply evolve Porygon into its two other forms.

 

Space-time distortions

To find Porygon, Porygon2 and Porygon-Z, you need to go to the Crimson Mirelands area, as that is the only place where you can find them. Stay in the area and wait for the notification “A space-time distortion seems to be about to open! “, because they only appear in the distortions of the Crimson Mirelands. 

If you just want to complete your Pokédex, find a Porygon and evolve it using the Upgrade and Dubious Disc items to get its two other forms.
