yes
Yes, but you have to get it from a Nintendo event (If they have any new events for Arceus) or trade with someone who got it from an older event.
u could trade it from someone else or get it from an event
you need to trade with someone who got him through a Nintendo event
trade with someone who has it
Trade.
the only way you can obtain arceus without an action replay is to participate in a Pokemon event. arceus was given out on a movie event. you can also trade with others online on the global terminal or trading friend codes with someone who does have arceus.
yes.
I'm assuming you mean Arceus. Arceus was an event only Pokemon so unless you can find someone who can trade you one, it is unobtainable.
You'd have to trade with someone who has Pearl to get Palkia in Diamond. Arceus' event was never run, there's no legitimate way to obtain him, though you can use a cheat device to trigger the event.
get an arceus of platinum and trade to soulsilver then go to the ruins.
No, but you will be able to catch Palkia, Dialga or Giratina.
Arceus is in the hall of origins directly above spear pillar you will need the azelf flute(event item) to make the stair case appear that leads to arceus(not easy to get)You had to get Arceus in an event. The event already ended so maybe you can get some codes.(I don't know any codes) Or you can trade with someone else who has Arceus. Then you can get to The Ruins of Alph and get Palkia, Dialga, or Girantina with Adament orb. Then you can trade back(unless you're keeping it)
