You can catch Regigigas via special download
You need to trade them from a Gamboy advance game where you can catch them.
You will need the three Regies (Regirock, Registeel, Regice) from diamond pearl, actionreplay... however, to catch you will need 3 other Regies or a Regigigas from the other games in order to catch the three Regies on pokémon platinum. After you caugth those Regies, you can catch Regigigas at snowpoint city temple. Another way is to get a lagre steek of won battles at the battletower to battle the tower tycoon, he has a Regigigas in he's party. After you saw Regigigas you can trade him via the global trade system (GBS).
email me at rohan@one.com.au and ill trade regies for free or u just have get from sphire
you need to go to snowpoint city and go to snowpoint temple BUT to get in YOU NEED TO GET THE THREE REGIES HOPES THIS HELPS:)
The trick will NOT work. You NEED Wailord in the last slot of your party pokemon.
u cant u can only get them from sapphire; emerald or ruby.
Go to GameStop or Walmart and buy an action replay DS, it is in the game accesories section okay. It has cheats on it for Pokemon and u can add cheats by searching action replay codes on the internet. It is that simple.
Migrate them from hoenn
Well you cannot CATCH Regigigas without the other 3 Regi's. Your only other options are trade with someone that does have one, use cheats on an r4 or buy an Action Replay Hope this helped :)
their are no regies in pearl or diamond besides regigigs but u need the three regies to get him in the snowpoint temple.
no
well,i cant think you could but you can catch the regies answer no
you must trade them
regigigas
there the home of the regies
You can if you want to.
IN D/P and platinum after you get the regies you need to have the three regis in your party and off you go to snowpoint temple to catch regigigas
