After you beat the elite 4.Talk to the guy in the weather institute if hwe says there is a down pour on route __ go to that route and kyogre will be there, if he says there is a drought on route __ go there and groudon will be there. Put it to sleep or paralize it. get it to red hp then use ultra balls!
No. -.- You can capture it without defeating them.
Probably trade with Ruby.

There is no such thing as a "super form" for Groudon, Kyogre, and Rayquaza, and there is no way to obtain these Pokemon in Pokemon Pearl without the use of an external cheating device. However, you can capture these three Pokemon in Pokemon Ruby, Sapphire, or Emerald and import them to your Pearl game through Pal Park on Route 221.
you can`t catch kyogre or groudon or both of them without linking them from sapphire, ruby or emerald version.
Legendary pokemon you can find in emerald are (without cheats & events) Rayquaza, Groudon, Kyogre, Regirock, Regice, and Registeel.You can get latios OR latias in pokemon emerald too.rayquaza,kyogre,grouden,jirachi,deoxys and i think mew
You would have to get a groudon from someone else if you wanted one before you beat the game.
Get Pokemon emerald and then you can get all three without cheats or trading
Not without cheating. Ruby can get Groudon and Rayquaza, Saphire can get kygore and rayquaza, but only Emerald can get them all.
Regirock, Regiice, Registeel, Rayquaza, Kyogre, Groudon, Latios or Latias
When you capture all 200 Pokemon and talk to the director in lilycove city.
You can't catch Groudon in Sapphire. Groudon is avaible only in Ruby and Emerald.
