throw great balls, ultra balls or master balls at them
The biggest factor: Luck.
The best way to improve your luck: Reduce the reggie's Hp to red (or using a move called False Swipe, to 1) and put them to sleep. Then use ultra balls, and it could still take quite a few tries. Just be patient.
And save before the battle. You'll probably have to try more than once.
No.
Trade with Pal Park.
You can't. You have to catch them in the hoenn region and then transfer them via pal park. Then, with them in your party, you can go to snowpoint temple and catch regigigas. by using action replay for ds but it will take time to do it though
The 3 reggies are not in platinum they are only in the hoenn region unless you use cheats.
nope cause all the other reggies will awake reggigas from his sleep.
Yes, but only with a certain Regigigas that was given away in an event; this event has passed long ago. Otherwise, you have to trade or import from a previous game.
yes
kyogre, groudon, raquaza, jarachi (I think), deoxys (I think), latios, latias, the three reggies (regigigas couldn't be caught) and some more. I think.
yes if u got the nat. pokedex 1in mt corenet,1 in a island , 1 behind the leugue,and 1 in snowpointtemple.put 1st three in party and go to the temple.then redgigigas will be awakened!
you can't you have to import them from Pokemon emerald
Reggie wedgie,
After you get all three Reggies (Regice, Registeel and Regirock) there is not much else to do with them seeing as you most likely caught them on the pokemon sapphire/ruby/emerald game. For either Pokemon diamond, pearl or platinum you can trade the three reggies onto it and go to the sacred chamber place which is the town below the snowpoint city gym and with all three reggies in your inventory you can unlock an entrance which leads to Regigas (sorry if spelt wrong been a while since played) it is very powerful and is level 70.
