Transfer the Arceus from Platinum that was released in a special event.
you could get a giritina from a trade or action replay
no
you need to beat or catch giritina.
After you catch giritina youll come to spring field and it will be there in the grass!
go to turn back cave
giritina, palkia and dialga
Im sorry but no
you have have to catch giritina at the spear pillar on mt coronet
trade for it, but kinda unlikely, or catch it if you are a gold member.
You can't. Use Poke'transfer to get one from sinnoh.
No, only pass the part with Giratina. You don't have to catch it. U can still catch giratina in disortation cave.
yah! check on youtube to find out
