you cant get all the regis only regigigas.
u cant.. only in platinum
u have to get all three regis and then go to the temple in snowpoint city
you can't get the three regis but, if you have pokemon sapir\rubi\emerald version on the gameboy advance, you can tke the three regis through the pal park in route 221 (in south). *there are three caves that may be the caves of the three regis but i don't know what to do there.
Regigigas is Pokemon #486 on Pokemon Platinum. To get it, go to the Snowpoint Temple with Regirock, Registeel, and Regice.
you only can find him in snowpoint temple in snowpoint city but you must have all three regis. bring all three regis go up to him and press A and the three regis will awekening him. hes a level 1 so have a goodb time catching him.
get all of the regis in your party and bring the to that place where he is a statue to revive it
First, you have to get all three regis, then you go in snowpoint temple, go to where the "statue" is and it will be a regigias. Finally just talk to it.
buy the Pokemon platinum book
I think you have to transfer the three regis from platinum version to pearl version but you have to have platinum version I think that's all I know
you find them in the cave
well, you actually have to get all the other regis from the gameboy games, then transfer them into platinum. if you want regigigas then you have to take one from sappire, ruby, and emerald, then go to the cave in snowpint city. there, all done!
You can get regigigas by either trading it from the event before the release of platinum, or migrate the regis from ruby/sapphire/emerald, then go to the cave in snowpoint city, and catch it while you have all 3 of the regis in your party.
