You cannot catch Manaphy in Pokémon Platinum, you can only acquire it in Pokémon Platinum via a cheating device, trading with someone or with transferring a Manaphy Egg from 1 of the 3 Pokémon Ranger games however the first Pokémon Ranger requires it to be bought new which is unlikely and the other 2 Pokémon Ranger games "Pokémon Ranger: Shadows of Almia" and "Pokémon Ranger: Guardian Signs" require the use of a Wi-Fi downloadable mission in order to receive the mission that allows you to get the Manaphy Egg however those 2 downloadable missions are no longer available.
no
You cant, but you can look at the book in the Pokemon mansion to see manaphy.
You need a Pokemon Ranger game.
Egg a manaphy with a ditto
you cant realy catch it on platinum so sorry. but you can get Pokemon diamond or perel and get manaphy on those games. hop dis helped :)
You can't, you catch it on another game and trade it over to platinum
Ya need to transfer an egg from Pokemon ranger
you need to put dito and manaphy in the daycare and they will have an egg
manaphy can only be received from a Pokemon ranger game to my knowledge
you can't catch manaphy on any game you must have the manaphy egg from the secret mission on Pokemon ranger. (you can see manaphy in trophy garden room where the fat guy and the butler is)
You can't catch it anywhere in the game. You need to breed a Manaphy with a Ditto in order to get it.
Unfortunately, you cannot catch manaphy in Pokemon platinum without cheating, which, I usually vote against, because it can easily corrupt your file and damage your game. You can always trade with someone who has it.
