First, you must trade it while holding an Upgrade to get Porygon 2. Then you must trade it again, but while holding a Dubious Disk, and voila! You have a Porygon Z!
I'm assuming you mean Porygon. Porygon evoles into Porygon2 then into PorygonZ. It evoles into both of them by being traded with an item. Porygon=porygon2 traded w/ upgrade, Porygon2=PorygonZ trade w/ dubious disk
Porygon. If Porygon is holding the Up-Grade, trade it to a friend and it will evolve into Porygon2. Give Porygon2 dubious disc, and it will evolve into PorygonZ. Porygon can be found in the Sinnoh region in the trophy garden, after gaining the National Dex, and in the Kanto Region, they can be found in the game corner prize exchange for the maximum amount of coins.
He doesn't evolve at a certain level. Somebody has to trade you a Porygon holding an Up-Grade. Or, you trade a porygon with an upgrade.and then trade back.right that instant it evolves into porygon2. then trade porygon2 holding a dubious disc and trade back. it will evolve into porygon-z. I didn't make any mistakes on this. believe me!!!!!!
Catch pokemon, battle, almost all the same stuff as the other games.
Attach the Upgrade to a Porygon and trade it to another game. It will evolve into Porygon2 when it arrives in the other game.
Porygon-Z is the final form of Porygon (and Porygon2). To evolve Porygon to Porygon2, trade it while it holds an Up-Grade item. To evolve Porygon2 to Porygon-Z, trade it while it holds a Dubious Disc item.
Porygon does not evolve at a given level: you have to trade it while it is holding the Up-Grade to evolve into Porygon2. Then trade that while holding the Dubious Disk to get a PorygonZ.
porygon evolves by trading it with a upgrade then trade with dubios disk. enjoy your porygonZ!
trade porygon2 with the item dubious disk to evolve the the Pokemon porygon two then get it back
You can give the Upgrade to Porygon and then trade it to a friend to make Porygon evolve into Porygon2, in order to evolve Porygon2 then give a Dubious Disc to Porygon2 and then trade it to someone and it'll evolve into a Porygon-Z.
You cannot. Trade with UpGrade to get Porygon2. Trade Porygon2 with Dubious Disk to get PorygonZ, but you have to trade either way.
You have to trade the Porygon 2 holding an item called "Dubious Disk" to a friend. It should evolve like any other trade-evolving Pokemon.
you have to trade it while its holding an up grade item
It evolves Porygon into Porygonz.
I'm assuming you mean Porygon. Porygon evoles into Porygon2 then into PorygonZ. It evoles into both of them by being traded with an item. Porygon=porygon2 traded w/ upgrade, Porygon2=PorygonZ trade w/ dubious disk
Give it to a Porygon and trade it. It will evolve into Porygon2.
give porygon (or possibly porygon 2) dubious disc ( i think you nick it from galactic hq) and trade him.
