You can not. The only games to get Giratina are:
you continue on to the next gym
Poke transfer
You can't games you find Giratina in are Pokemon Pearl, Diamond and Platinum if you want to get Giratina badly get Pokemon platinum because in that game he is the main Pokemon!
theres´s no giratina in the game so use action replay
You can catch the same Pokemon you can catch in diamond only now you can catch shaymin in 2 different forms,catch giratina in 2 forms and rotom in 5 forms.
no you cannot catch a giratina in black and white only trade
There is no possible way to find GIRATINA in Black. You'll have to migrate it from HeartGold, SoulSilver, Platinum, Pearl or Diamond. Hope this helped

Yes, you do have to save them in order to catch Giratina.
its been confirmed you can catch it in Pokemon platinum pearl and diamond
You walk into the portal Giratina leaves behind after capture.
You can't catch giratina in soul silver, you can only catch him in diamond, pearl, or platinum.
You need to catch Giratina or beat Giratina after that go to Lake Verity. You need HM Surf...
