sorry but you can't find it in Pokemon diamond/pearl without migrating regirock from Pokemon ruby, sapphire, or emerald. But I think there is a cheat on the action replay for it, but I don't know the cheat.
free the three legendry Pokemon ,regirock,regice,registeel.or use action replay
you don't need regigigas for registeel. you need reegisteel, regirock and regice for regigigas on Pokemon pearl or diamond
Regirock is a Rock type pokemon.
Regirock does not evove
Platinum has the following Pokemon in it that aren't in Pearl: Regirock Registeel Regice Articuno Zapdos Moltres Tangela Tangrowth and of course all the new forms.
there is no regirock in Pokemon pearl,migrate please to get regirock
There is no way to send regice regirock and registeel from ranger to pearl. the only Pokemon that can be transferred from ranger to pearl is the manaphy egg.
You have to have regiice, registeel and regirock to be able to fight him
you cant unless you have a regigigas
you need regice, regirock, and registeel from Saphire/Ruby/Emeraled
its probably in another game you can do that
there is not regice in pearl. but if you have ruby, emerald, or sapphire you could trade regice,regirock, and registeel to get rigigious.
just bring regirock registeel and regice to regigias! regigias will be at lv70
you can only get it by Action Replay otherwise u cant
free the three legendry Pokemon ,regirock,regice,registeel.or use action replay
Regigigas is in the Snowpoint Temple but you need Regice,Regirock and Registeel in your team to awaken him
No, you'll have to trade it from Platnium. Which in Platnium you find it in the Rock Peak Ruins.
