evolve all of your pokemon,recruit all the legendary pokemon.
Do the usual of carrying out missions for a few days. Manaphy will come back.
After you do a couple of missions Manaphy comes back and says Walrein tryed to kill me! And you go to Deep Sea and find the Golden Sword (15th floor) and chop off Walreins head at the end of the Dungeon.
first manaphy has to tell you about the marine resort. second you must have a secret slab or a mystery part in you bag you do not have to use or hold them then go to dark crater b6f and keep fighting him until you recruit him
You need to go special event
In the Platinum pokedex, number 151-or the Pokemon after Palkia-is none other than Manaphy. Manaphy can be obtained after you beat the manaphy egg mission in Pokemon rangers. You then can transfer it to platinum via mystery gift. what you do you go to the Pokemon mation and go to the oner and behind him theres a book talk to the book and it will show you a picture of manaphy
Manaphy isn't in this game he's in mystery dungeon explorers of Time & darkness or Sky
craggy coast
you have to save the phione and beat garados
After Manaphy leaves and you beat the whole game, sleep for a few days, and Manaphy will come back and join your team.
beat darkria and manaphy will jion your team and after 3 days manaphy will tell you whare mirene resort is.
evolve,and recycle until you get a new place
Surrounded Sea
I can't remember at what point he joins your team, but if you keep playing the story line, he will eventually join, I think.
Whatever you want. It won't make a difference. The one thing that happens is that you can visit marine resort (as a dungeon.)
you go to surrounded sea and complete the dungeon and find an egg.at home it hatches and becomes manaphy.
I don't think there is a Manaphy on Blue Rescue Team.
not much happens, go on a few missions, and manaphy will return to you
