You can only get them if you received the special lv100 Regigas (in the Japan only event, I think)
Or you have to transfer them from R/S/E.
Either way will work.
migrate a s s
you can get them after you beat the elite four a hundred times
just get the three regis, then go to the temple in snowpoint city.
You need relicanth and wailord to catch the regis in sapphire/ruby/emerald. You cannot catch the three regis in platinum unless you have the event Regigigas (this event has now ended). If you have the special regigigas in your party, three new caves will open up in Sinnoh and you will be able to catch the three regis.
i bleve so
Snowpoint Temple, but you must have the other three regis first.
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.
Stupids!!!!!you need to get the three regis by trade or in the pal park,then goto the temple on snowpiont city
get the three regis then go to tower at snow point and talk to the lady and she'll let you in ( make sure the regis are with you)
You can't, you can only get the three regi's in Pokémon Platinum with the lvl 100 event REGIGAS.
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.
Sorry dude, you can't get registeel in platinum without a cheat. But you can catch Regigigas in Platinum, but you'll need all three of the Regis to get him.
