Migrate from gba with a ds. Either ruby, emerald or sapphire. Or, you can get an event Regigigas and one appears in Iceberg Ruins
You can only get regi ice in sapphire,ruby,and emerald.
Of Course
No, but another Regi exists in this game. Also in the game that is coming out (Pokemon Platinum) Regigas has a new form.
i do not to know
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 ^.^
