you have to talk to mr backlot in the Pokemon mansion south of hearthome city after receiving the national dex and beating the elite four if he says a porygon came up to him you can look for porygon until you find one in the trophy garden out back
PS. you only have a 2% chance of finding it in the trophy garden at any time
The Up-Grade evolves Porygon into Porygon2 =).
It is used to evolve Proygon2 into Porygon-z.
In Pokemon Platinum (I don't know about Diamond and Pearl), Porygon is located in a house directly behind the Pokemon Center. If you want to evolve into Porygon 2, trade it holding a Up-Grade, and if you want to evolve Porygon 2 into Porygon Z, trade it holding a Dubious Disk. I do not know where htese items are found. If you want to get Porygon the harder way, use Pokecheck.
give porygon (or possibly porygon 2) dubious disc ( i think you nick it from galactic hq) and trade him.
Porygon-Z is a Normal type pokemon.
you cant find a porygon ,you can find it in Pokemon pearl or on platinum
Porygon is found rarely in the Trophy Garden.
the upgrade is used to evolve porygon into porygon-z
That Would be Either Porygon or Porygon-2

At the Pokemon mansion. You can talk to the owner and on rare occasions, he will say that a Porygon is in his backyard, so go there
You mean Porygon. You have to trade.
it evolves porygon into prygon z and the up grade evolves it into porygon 2
You will have to evolve a Porygon. By evolving it you have to trade it while it is holding an Up-Grade.
You can find porygon in the trophy garden. talk to mr balchalot and heel say he saw a pokemon and that when you go to the garden
it is one of the daily Pokemon in trophy garden
You need to double slot and get it from an advance game.
