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
To catch it, do this. First, you get porygon in the house behind the Pokemon center in veilstone city. Then, trade it while it's holding an Upgrade, which can be found in the team galactic building in eterna city.
You can see it on route 216. One of the trainers has an ambipom and a porygon2.
Trade it from Fire Red/Leaf Green, with Up-Grade attached to it.
you evolve a porygon with upgrade witch prof oak gives you once you complete your pokedex he is located in the emty house in eterna city.
there is a trainer in route 216
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
