You cannot find Regigigas in pokemon black and white. You can obtain it by trading with someone who have Pokemon Diamond/Pearl/Platinum.
regigigas don't have a new form in Pokemon platinum REGIGIGAS IS LEVEL ONE!!!!!!!!!!!!
regigigas is only avaible in Pokemon diamond, pearl or platinum
regigigas is not a Pokemon you can obtain in ruby because regigigas was made in diamond and pearl and platinum so you can't get it in ruby ever.
Regigigas was not made during the Emerald era, you can only get the 3 Regis. Regigigas is only obtainable in Diamond, Pearl, Platinum +
you cant get all the regis only regigigas.
get a GBA to get it
You cannot get Regigigas for Pokemon Ruby since it is a newer generation of Pokemon. It is for Pokemon Diamond, Pearl and Platinum
Regigigas is a Pokemon from Diamond/Pearl and Platinum so it is a newer generation of Pokemon. Therefore, you cannot get it
I am sorry it's impossible to get Regigigas in Pokemon Emerald. You can only get it in Pokemon Diamond, Pearl or Platinum.
You had to get it in a Nintendo event for D&P, then trade it over.
Regigigas is Pokemon #486 on Pokemon Platinum. To get it, go to the Snowpoint Temple with Regirock, Registeel, and Regice.
