The only way to catch Arceus in Pokemon Platinum is by using the Azure Flute or cheating. The Azure Flute is an event item that sadly was never distributed. This means the only way to catch Arceus is by cheating.
There is no event where you can catch Arceus, you just interact him in the Hall of Origin, but you need to blow on the Azure Flute
if you have the azure flute but dont have him you could go to spear pillar and catch arceus
You need to get the azure flute by wi fi event
the flute
as long as you haven't beat it yet and you have the azure flute, you can.
You can catch Arceus in Pokemon Platinum Version, but only by obtaining it through a Nintendo event, unless a Gameshark or Action Replay is involved. Legitimately, the event gives you an Azure Flute when you talk to the green person next to a Pokemart in any town, and when the flute is used at Spear Pillar you can fight and catch Arceus.
The strongest Pokemon in Platinum is probably Arceus, to get Arceus, you need a mystery event, but that event is finished now. :( The second strongest Pokemon would probably have to be Giratina, or probably dialga or palkia.
go threw the place and find him at the last part same with arceus but need arzura flute
there is no azure flute but you can get arceus November 7-15.
You can catch Arceus in Platinum with the Azure Flute which is obtainable through Official Nintendo Events but otherwise, you will not usually be able to get an Arceus from someone.
