You can't get a Regigigas in Sapphire, Ruby or Emerald. Regigigas is a Generation IV Pokemon, and Sapphire, Ruby and Emerald are Generation III games.
you need to have atleast beat the Pokemon league once in dimond and you should be able to migrate.You also need either emerald version, Sapphire version, or ruby version catch regice, regirock, registeel then migrate into dimond version
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 can't get regigigas in ruby.
You have to beet the elite four and inside there is regi gigas
In the snowpoint temple you need the 3 regi's from ruby,sapphire and emerald to wake up regigigas.
DotBraille is Regi's language in Ruby, Sapphire and Emerald. By reading them in the walls and de-coding them, you can find Regi's (expect Regigas!).
first before you should even think about going in, you have to get your national dex and beat the elite four. then you go to the temple and the person at the front at first doesn't let you in, but then a girl comes and talks to the lady and then you can go in. in the temple is regi gigas. ( i don't know how to spell it so sorry if i did) you will need regi rock, regi steel, and regi ice to get him.
The only ways to get Regi Rock in pearl version is to: 1. migrate it from Ruby, Sapphire, or Emerald 2. Get a gameshark and use a code
You can only get regi ice in sapphire,ruby,and emerald.
you don't you must trade from Emerald, Sapphire or Ruby.
Kyogre and latias. regi-rock, regi-ice, regi-steel
Regice will appear in the Island Cave on the bottom floor after you solve the Sealed Chamber Mystery.
