A Veteran in Victory Road has a porygon z. to get a porygon z, trade a porygon holding an up-grade (from the eterna galactic building go behind Jupiter to get an up-grade) then you get porygon 2. trade porygon 2 holding a dubious disk to get porygon z. now you have 3 new Pokemon to your pokedex!
P.S. i don't know how i got my dubious disk but you get it somewhere along the lines. Also, if you don't know where to get porygon a man in the home northern of the Pokemon center has one. bring space in your party. the porygon is at level 20.
I think you get dubious disk when you go into the cave in Solaceon Town where the unknown are
Link trade Porygone while it holds the Up-Grade
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.
You must evolve Porygon (From Celadon) using the UpGrade to Porygon 2.
Porygon-Z
Fly to Veilstone city. And there is two houses behind the Pokemon center go into the right one and talk to a guy who will give you a porygon then you can evolve it in trade making it hold the Up-grade. Good luck!
i think you see it on a route near snowpoint city its covered with snow
An Up-Grade is an item that evolves the Pokemon Porygon when Porygon is traded while holding it. Porygon evolves into Porygon 2.
find porgon 1 and catch it then in the closest bit of grass you will see porgon 2
you must trad a porygon holding an up-grade
you give porygon the upgrade then trade it to get a porygon 2 then you give your porygon 2 another upgrade and trade yet again to get a porygon-z
trade while holding up grade and it will evolve into porygon 2
In Pokemon Platinum, Porygon-2 can evolve into Porygon-Z using the Up-Grade. I do not believe it serves any other purposes.
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.
one of the scientist in the galactic warehouse.
Have a Porygon hold it and trade it.When the other person gets it, it will evolve into a Porygon-2.
Link trade Porygone while it holds the Up-Grade
evolve porygon from veilstone city
