once you have beaten the elite 4, go to the weather station on route 119. I suggest flying to Fortree, then biking down. go upstairs, and the scientist will say "There have been severe droughts/huge stroms on route __. Could that mean... somewhere on route __..." in the blank, he'll say a route. Go to that route, and search for a cave if it's a drought, or if it's a storm, a small place to dive to. Both the cave and the diving place will not have been there before. If it's a drought, it's Kyogre. If it's a storm, it's Groudon.
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.
you can only get groudon on Pokemon ruby.
first go to the cave of origin in sootopolis, and go to the end, you will see groudon there
go to the cave of origin in sootopolis city
Legindaries are Groudon,Rayquaza,regice,registeel,regirock.If you want more go get a Pokemon ruby guide book
What you have to do is go to route 221 and theres this house somwhere there go in save turn off and put your ruby in your ds and have groudon in your party then turn diamond on and go to the man and he will let you in to this place and look for groudon then catch it ta dar but there will be no groudon in ruby and you cant give it back
Go to Sootopolis City.
You have to go to the cave of origin in Sootopolis city which you have to use dive to go there.
Unfortunately, you can not get groudon in FireRed without trading.you have to go to oaks lab when you have 110 on your pokedex and then he will say Gary is gay and you get groudonYou have to trade from Pokemon Sapphire Ruby or Emerald to get Groudon
You don't get Kyogre in Ruby; instead, you get Groudon. If you want Kyogre, you have to trade one from a Sapphire or Emerald game.
you go to the sky pillar and awaken rayquaza
after beeting him in the battle? if that is your question,you battle the gym leader in that soot place
