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.
You can only get regi ice in sapphire,ruby,and emerald.
There are four Regi pokemon. They are Regirock, Regice, Registeel, and Regigigas.
by getting all three regi`s from Pokemon emerald, then you can go in and find the fourth regi. (Regigigas)

You can't get regigigas in ruby.
You have to beet the elite four and inside there is regi gigas
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 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

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.
