To awaken Regigigas you need to migrate from Ruby/Sapphire/Emerald the three Regis.
Regigigas is a Sinnoh pokemon. Not a Hoenn.
Regigigas is a pure Normal-type Pokemon.
From what I have heard, Regigigas is a Hoenn pokemon. You will have to trade it from Platnium. Sorry!
Simple answer: you can't, because Regigigas appears only in Generation IV (Diamond/Pearl/Platinum). However, in DPPt, if you get all three Regi's from Ruby and take them to Regigigas, it will awaken. To get Regice/Regirock/Registeel, there is an underwater ruins on Route 131 (west of Pacifidlog City) that has specific requirements to enter. Once the requirements are met there, the three tombs will open and you can battle them.
Regigigas does not appear in Ruby. Regigigas is a fourth Generation Pokemon, and Ruby is a Third Generation Game.
