porygon
you make a porygon hold it and then when you trade it it evolves into porygon2
Get a porygon 2 make it hold the upgrade and then trade. -Hope I Helped!
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!!!!!!
you can make porygon hold it then you trade it and it turns into a porygon-2
well first you gotta get a porygon. then let it hold the upgrade. then trade it and you'll get porygon 2. trade again with dubious disc to get porygon z. Only Porygon needs Upgrade and you need that upgrade to trade for it to evolve. You need to trade it together with the upgrade for it to evolve.
im pretty sure that an onix evolves when holding a dragon scale. only problem is, is that you have to trade while it's holding it. :/
Give Porygon an upgrade to hold and then trade it. Also, if you want a Porygon-Z give Porygon2 a Dubious disc to hold and then trade it.
No, you don't have to. Its only there to give you an upgrade i think it is when you reach the top. the upgrades for a porygon (found at the slots) and when you make it hold it then trade it it evolves if you didnt know. if you did well meh i told you anyways.
Have it hold upgrade trade it to a friend then take it back to receive porygon2.
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.
To evolve Porygon to Porygon2, you will need to have it hold an Upgrade and trade it. You can get Porygon-Z by having Porygon hold a Dubious Disk and trade it.
Have Electabuzz hold a Electirizer and trade it with someone to evolve it into an Electivire.
