you need to get them from ruby sapphire or emerald in which they are all catchable or from firered or leafgreen if you have traded them over by inserting that cartridge into the gba slot in the ds and going to pal park
try catching regierock,regiestael,and regieice.
you have to get him in Pokemon emerald, Sapphire or ruby. then send him through the pal park
The bosses are: Koffing/Zubat, Drowzee, Uxie (Note: You are only battling an illusion Groudon conjured from Uxie), Manetric and his Electrike, Mespirit, Grovyle, Spiritomb, Kabutops and the Omastar Bros, Dusknior and his Sablye, Primal Dialga, The whole Guild, Carnivine, Grimer/Muk, Frostlass, Regierock/Regieice/Regiesteel, Regiegigias and some Hitmonlee/Brongzong, Gyrados, Palkia, Darkrai, The special episode bosses,And the legendaries/ Rare ones ( Exp. Manaphy and Phione).
To get in the temple you have to beat the elite four once you've done that you have to migrate all the regies(regieice, regiesteel, and regierock)to your game then catch them in the pal park, but first finish your national pokedex(I recomend cheating)get all regies in your party after go to the temple and go all the way tho the bottom and theres regigigas! Then all you have to do is find your way through sliding on the ice. hope that helps!!!!:D BYYYYYYYYYY!!!!!!

R/S/E: Ancient Tomb Pt: Iron Island All others: Trade
no legendary Pokemon or genderless Pokemon can make eggs/breed. hope i help :)
You go somewhere deep in iron island. Then you'll see silver dots that look like Registeel's eyes.
You can't anymore unless you received regigigas in the Pokemon event. If you have, go to the end of Iron Island and he'll be in there.
