you have to do the mission in Pokemon rangers(manaphy egg mission)and trade it to your platinum you can get phione by breeding manaphy with ditto at the day care.(its not fair to have 2 games for just a Pokemon in platinum)
Leave it in the Daycare with Ditto.
The only way to get a Manaphy is to beat Pokemon Ranger, do the bonus mission where you save a Manaphy egg, then transfer the egg over to Diamond, Pearl, or Platinum, then trade from Diamond, Pearl, or Platinum.
you need to clear Pokemon ranger and trade the manaphy egg to diamond/pearl and then you can trade it to platinum but i don't think there is any other way to get manaphy except action replay but if you do that get a magmar or macargo to hatch the manaphy egg faster
There is no trainer in Pokemon Platinum with a Manaphy. However, you can trade with someone who has a Manaphy, or complete the special Ranger mission in Pokemon Ranger and transfer the Manaphy egg over to Pokemon Diamond, Pearl, or Platinum.
Egg a manaphy with a ditto
You don't need action replay but, just catch all the legendary pokemon. (that you can possibly catch. Without action replay) So go to where the professor is go into his lab. Do the mission he asks you which is the Manaphy egg, get it then go back. If you have 2 D.S. you can bring the Manaphy egg to Diamond Pearl or platinum!! Sorry If I didn't really ansewer your question. :)
Pokemon ranger, ranger net find manaphy egg mission compleat it put manaphy egg on dimond pearl or platinum hach it then breed with ditto
That is the only way to get a manaphy without cheating. once you get the egg in Pokemon Ranger then trade it to diamond/pearl/platinum and when it hatches then you have got a manaphy.
Yes, it does work.
You have to transfer it from Pokémon Ranger. Or cheat
Yes you can but you must have Pokemon ranger shadows of Almia And then go to the poke-mart after doing the manaphy egg mission!
