It evolves Porygon into Porygonz.
give it a dubious disk and trade it
Attatch it to Porygon2 and trade it- it evolves into PorygonZ
You cannot do that unless you have Pokemon rangers 2. So if you want another riolu you have to get Pokemon rangers 2.
give porygon (or possibly porygon 2) dubious disc ( i think you nick it from galactic hq) and trade him.
It evolves Porygon to Porygon2 through trade.Dubious disc will then change Porygon2 to PorygonZ
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.
trade porygon2 with the item dubious disk to evolve the the Pokemon porygon two then get it back
You need Regice, Regirock, and Registeel.
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
Number 77 is Electrode found in the Altru tower.
You can't! You have to have any of the three "Pokemon Rangers", "Pokemon Rangers Shadow Of Almia", or "Pokemon Rangers Guardian Signs" and have a mystery egg mission which is a special event and after the mission, you have to have 2 DS's and transfer your Mystery Egg to your game and there you go!P.S. I've never tried this.
