In pokemon platinum, where can you find porygon 2? I know you have to trade with someone but where can you find a trainer that wants to battle that has a porygon2? HELP!

you dont trade anything, a man in valestone city just gives u it.He is near the pokemon center,and there no person that has it to battle u.well he gives u a porygon,and u have to evolve it

what he said is true but HARD find a freind that has one and battle it.

If you have FR/LG or HG/SS, you can buy one at the Celadon Game Corner. Then trade (HG/SS) or Pal park(FR/LG) it into platinum. Those tricks are what got me a complete National-Dex. Also, if you have an Action Replay, you can use the Modifier.
