No, to get Regigigas you must have Regirock, Registeel, and Regice in your party and go to the temple in Snowpoint City.
You have to have a special Regigigas from an event.
get regirock regice and registeal go to regigigas and click a on him
you need to have a special regigigas in your party for them to appear. you can only get the right regigigas through an event (maybe you can also get a good regigigas with the action replay). you can only get the 3 normal regis in platinum and not in pearl or diamond.
the arceus event
You have to get it in Pal Park from R/S/E.
One for every event Pokemon like Shaymin, Darkrai and the special Regigigas.
You could only get the movie Regigigas through special Nintendo events or through hacking the event Pokémon or by trading with someone else in order to get it.
Yes i think it does, the game has the event programmed into the game even if you dont trigger it with a regigigas. You could even trade a regigigas from D/P to trigger the event.
NO.
There is currently no info on any future events for a Regigigas.
Yeah. You can catch it in snowpoint temple. But remember you need regice,regirock & registeel hope i helped!
Unfortunately it seems Japan will only get that special event to find the Regi's and will get Regigas, but a way of getting him is by migrating the 3 regi's over via pal park and then taking all 3 to the snowpoint temple where you'll find Regigas at5 the bottom, he will be lvl 1, hope this helps Ive heard rumors of the special regigigas in lv. 100 in Europe in Pokeplus. The site pokecharms already told which citys of England he will be distributed. And there is a site disseminating the event: http://ms.Nintendo-Europe.com/regigigas/
