You have to explain more what game are you talking about Pearl/Diamond/Platinum?
My Brother!!!
Giratina can only be obtained in two ways: the Arceus event or trading one from a friend. Giratina cannot be found in the game through normal game play.
you can only get another by trading or hacking. Sorry.
In a way, yes. Your opponent will only see it as an Altered Forme Giratina, no matter what game there playing. As for trading, no. The Griseous orb will return to you automatically.
You can only get it by Trading from Platinum, Diamond or Pearl. But you can only get the Griseous Orb via the Event.
yes but you can only get it by trading the special event arceus to soulsilver then getting the lv. 1 giratina
No, Giratina's Origin Forme is unavailable in Diamond, Pearl and Battle Revolution. Trading it to Diamond and Pearl and/or copying it to Battle Revolution, it'll revert back to its Altered Forme.
Without trading, cheating, or Nintendo events, you can get Dialga, Uxie, Azelf, Mesprit, Heatran, Giratina, and Cresselia.
