You have to transfer them over from Pokemon Ruby, Saphire, or Emerald.
you want all other regis(regice, regirock) and mightuena.
you could find it in the snow point city in side the temple. but it sometimes says something and you could also find reggigigas inside along with reggice.
If you mean "a body of rock, a body of ice, and a body of steel, when gathers the three Pokemon the king shall appear," you need a reggice, registeel, and a regirock. Migrate them from Pokemon sapphire, ruby, or emerald. But that's not wat ur talking about is it? u can get an icy rock at the Underground!!!!!
you must get the three Pokemon reggirock reggisteel and reggice to get them you must have sapphire, ruby or emerald i don t know how you get them on there sorry but i have looked it up before
reggisteel is in route 220 reggirock arrives in your secrent base when your base is in a rock and reggice is in seafloor island this was teatsed and it works 100% im really sherr because i have all the reggis (hint when reggi rock appears in your base hes black level 80!! its true man!!)
you get reggigas when you get reggirock, reggisteal, and reggice and go back to snow point temple to the reggigas statue and battle him

Moltres,Zapdos,Articuno,Entie,Suicune,Raikou...hmmm...Cressilia...Ho-oh...Lugia...Latios...Latias...Thats like all i can think of oh wait! Reggigas,Reggirock,Reggice,Reggisteel, And i think i spelled those wrong to but yea :)
you are not allowed to unless you use GameShark.
you get the level 100 regigigas in the event (pokemon.com) then you go to mt cornet and you find a ice cave somewhere in there inside the cave there will be button looking things you step on them and go to the statue P.S.the regigigas from the event must be with u all the time
you need wailord (route 139) in the front of your party and relicanth( underwater somewhere) at the end of your party

When you take all the reggis to the chaber in Diamond/pearl you get a chans to capture the legendary Pokemon "Regigigas". He is a much bigger reggi than the other, and he is Normal type.

Regice can be found by going to petalburg city and going over toward the woods and surfing down after going as far left as possible when you run into an opening you go left and up till you reach a cave there is where it can be found but before the cave will open you must have already opened the doors by going to the under water cave in the fast currents with a relicanth and wailord.
First, go to dewford town (after you have defeated the poke league) and go to the top of the town (make sure you have a Pokemon that knows the move surf). Next go left then straight and keep going until you cant go anymore. then go straight up until you find a small island with trees, go to the left edge of the island and then go straight up and then keep surfing from their (when you see a spot where you can start surfing again). P.s the discribing isn't that good
