Migrate from Pokemon ruby emerald Sapphire
The three regis, regirock regice and registeel.
For Pokemon ruby you can catch the three regis, rayquaza, groudon, and latios/latias. In sapphire you can catch the three regis, rayquaza, kyogre, and latios/latias. However, in emerald you can catch kyogre, groudon, rayquaza, the three regis, and latios/latias.
No you cannot get the regis nor any hoenn Pokemon all must be traded to you from ruby, sapphire and emerald.
Trade someone with Ruby,Sapphire,and Emerald.
You must Migrate from Sapphire, Ruby or Emrald.
All 3 must be traded from either ruby, sapphire or emerald.
You can find the three Regis in chamber-like places.Regirock is in Desert Ruins,Regice is in Island Cave,Registeel is in Acient Tomb.Shadowfritsch4
either you get Pokemon emerald or Sapphire, and if you want them on diamond or pearl you have to beat the elite four and then migrate.
Actually you're wrong you can NOT get the regis in Pokemon diamond, to get the regis you need Pokemon ruby/Sapphire/emerald you can get all three regis there(regi ice, regi steel, regi rock) althought if you migrate all of the regis onto Pokemon diamond you can get regi gigas(king regi) you will find him in the snowpoint temple after beating the elite four. Thanks hope i helped ^.^
You need to transfer all 3 of the regis from you ruby,sapphire, or Emeralds game packs
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.
