the arceus event
i think a while after platuinum comes out
it came out in December
The Pokémon Arceus will come out in the 12th Pokémon movie. It came out in July 18th, 2009 in Japan so most likely it will come out a year after that in 2010.
make sure you have only arceus in your party. there is a PC in the hiker's house. it also has to be the event arceus from toys r us.
You use it to trigger Arceus to come out at the beginning dimension on Spear Pillar. Arceus is lv 80
I think in the spring but im sure in 2010.
you need to order Pokemon heartgold and soulsilver when they come out
To get ARCEUS in platinum. Get the Azure Flute (the event hasn't come out yet). Go to the Spear Pillar and it will ask to play it. Stairs will then appear and at the top is the hall of origin. ARCEUS will be there at Level 80
