You would have to get a groudon from someone else if you wanted one before you beat the game.
No. -.- You can capture it without defeating them.
You don't awaken him until you beat the elite 4. Then go to the weather institute and they will tell you where to go for each Pokemon KYOGRE/GROUDON.
first you beat the elite 4 then go to meteor falls on route 114, go to steven and battle him, groudon will apear if you beat him
Go Beat the elite four. And catch the legendaries like Kyogre and groudon. =]. -egyoshi
you beat Archie on emerald
You should use mostly grass and flying types they would be most effective
first you have to beat team magma completely and then you must stop groudon and kyogre from fighting you can do that by calling rayquaza
Groudon is obtainable in Pokemon Emerald only after you beat the Elite Four. After you do so, go to the Weather Institute West of Fortree City, and go to the Second Floor. Speak to the scientist on the far left and he will tell you where Groudon is. You can do the same tactic for Kyogre.
