You can't you need to miagrate it from leaf green ... i thnk
you have to go to where the trophy garden is.
You cannot catch Porygon2 in the wild, you will have to trade a Porygon holding an Up-grade to evolve it into Porygon2.
you can catch a porygon in Pokemon diamond by going to the old man in the mansion and out to the trophy garden. You also need the national dex to catch a porygon . walk around the grass and in a little while it will appear.
I believe the only method to obtaining Porygon 2 is by evolution. You do this by giving a Porygon an 'Up-Grade' item and trading it.
yes up-grade is used to evolve a porygon
you cant find a porygon ,you can find it in Pokemon pearl or on platinum
Im pretty sure you cant find porygon2 on diamond or pearl. But you can find porygon in backlot's mansion (the garden).
Porygon-Z does not evolve any further.
In Casino award room
you can only do it on pearl/diamond and platinum
you have to go to where the trophy garden is.
The national pokedex.
You can obtain porygon at the pokemon mansion go to mr.backlots room answer yes to both questions and he will tell you a pokemon ran up to him and gave him a smooch on the cheek that pokemon might be porygon check every day good luck!
Go to the Trophy Garden which is in the Pokemon Mansion. porygon is rare in Pokemon Diamond, so using the Poke Radar would be easier.
you can find porygon in mr.backlot's garden after talking to him
in a science lab from a scientist i think
doubius it stands for dou disk mean disk number 2 it is the second upgrade for porygon trade a porygon 2 with it and you will get porygon z
