I just got Giratina into my copy of Pokémon Y, and I'm wondering how I can get Giratina into its Origin Forme. Any way how?
>While it is not known to evolve to or from any other Pokémon, it has a second forme activated by giving Giratina a Griseous Orb to hold. Its original forme, Altered Forme, will then become Origin Forme. -Bulbapedia
Just give it a Griseous Orb :)
The Griseous Orb is located in Terminus cave in the room where Zygarde is located with the Adamant orb and Lusterous orb
