Sorry but you have to catch Regice, Registeel and Regirock in order to catch Regigigas.
No. You can only catch the 3 regis, (regice, regirock, and registeel) and then in Diamond, Pearl, and Platinum if you migrate the 3 regis to your account you can get regigigas at the bottom of the snowpoint temple.
First get all other 266 Pokemon in the Browser then you will get a mission to go to hippodon temple. Catch the 3 Regis then go down a hole in the temple put the three regis on these things then you vs Regigigas
unfortunately you can't without regis
no it is not possible
you have to migrate the three regi legendaries from your ruby/sapphire/emerald version. when you have all three, go to Snowpoint City. from there you go into that building right above the gym. a girl will stop you but then the gym leader will tell you to go through ONLY if you have all three regis
I am guessing you have to get all three so you can get regigigias.
Regigigas requires all 3 of the other Regis to be present in order to be captured.
you can't
No, you have to transferr them.Shadowfritsch4
You Can't
i think you mean regigass and its in the northern city temple but you have to have all three regis ice stone steel without them he wont activate
Stupids!!!!!you need to get the three regis by trade or in the pal park,then goto the temple on snowpiont city
