you need to have the national pokedex
Migrate one from leafgreen.
In Pokemon platnom the door opens magically when you catch the newest Pokemon CROWLEY caught at an event and when you go tho the door it should be open.
no \ i caught over a hundred already!
You need to trade them from a Gamboy advance game where you can catch them.
Unfortunately, you must migrate the regies from ruby or sapphire. You cannot catch them in pearl/diamond.
Okay: 1:It's PLATINUM not PLATNOM. 2:It's a Pokemon game that's an upgraded version of Pokemon pearl and diamond.
There is no giratina in almia. The only legendaries are the gem gaurdians, events, and the regies.
migrate it from firered, or leafgreen
online? no
you don't
march 22
you need to go to snowpoint city and go to snowpoint temple BUT to get in YOU NEED TO GET THE THREE REGIES HOPES THIS HELPS:)
