In emerald, when you get to Sootopolis (however you spell it) city, where you get your 8th badge, but it's after you find the underground cavern and defeat maxie or archie, i dont remember which, Steven will show up and tell you to meet him in Sootopolis. Then, when you get there, you'll see Kyogre and Groudon in the center of the city fighting. This only happens on Emerald.
Kyogre because Kyogre is Water and Groudon is ground, which is weak to water.
you beat Archie on emerald
You have to come to the place where you caught Groudon/Kyogre, but you have to take both Groudon as Kyogre with you.
the fight is kinda corny kyogre and groudon can be seen fighting at sotopolis city the fight wil end til you wake rayquaza then rayquaza does a cry and both Pokemon disapear.
you either catch kyogre or groudon , then you go and find the one you didn't catch( you can trade with yourself with the help of a friend) and battle!
No, because groudon and kyogre are opponents.
They fight in Sootopolis City (Japanese: ルネシティRune City) (Emerald only)
blue orb for groudon and red orb for kyogre
kyogre
groudon is better
yes for groudon not kyogre
a sky dragon basically a third legendary that split the fight against kyogre and groudon.
