you have to unlock the 8th gym.and to do that you have to surf down from mossdeep city until you find deep water,then dive and find a cave then go in it and dive up and you will find a seafloorcavern.when you get to the surf part make sure you go through the top left door. and then your are going to find kyogre and archie.after you have to go to the cave of origin in sootopolis.when you get to a searten part,you have to catch or beat kyogre,then when you get out the 8th gym will be unlocked.
Sootopolis, and Kyogre is located there too :-).
In the elite 4 hes the champion
I don't know!Wallace appears in Ruby Sapphire and Emerald.Most likely from Emerald but there may be some elements from Ruby and Sapphire.
Wallace he was the former 8th gym leader in ruby and sapphire
I'm sorry to say it, but "that guy" is not a Pokemon. He is, however, the leader of the Sootopolis Gym. In Ruby and Sapphire, he was Wallace. But in Pokemon Emerald, he became Juan. Wallace then became the Elite Four Champion.
If you mean "Is Juan the leader in Pokemon ruby?", then no. It's Wallace who's the leader. Juan is leader only in Pokemon emerald. The champion is Wallace in Emerald, but Steven is the champion is Ruby and Sapphire.
you have to go to sootipoolis city which is next to mossdeep city
the same Pokemon as sapphire sealeo luvdisc whiscash seaking milotic
When you win Elite 4 and the Champion Wallace/Steven.
Defeat Wallace in sootopolis city, you can only come there by using dive.
It's because on Pokemon Ruby and Sapphire, Steven is the league champion and on Pokemon Emerald Wallace is the champion instead of the final Gym Leader. Juan doesn't exist on Ruby or Sapphire.
No, you only battle Steven because in Pokemon emerald Wallace is the champion.
