Battle tower medals? 2, but there are the other pikes to think of, too. That'd total up to 14 medals.
you have to go to the battle fronteir after you beat the game
=No, But there is a Battle Tower there. The battle frontier was added only to Emerald Version, and therefore is Completely unaccessible to ruby/Sapphire Version. Sorry.=
No there isn't. The cave is in Pokémon Emerald
The battle tower is where it has always been--the fight area. But now in platinum the area is called the battle frontier. The original idea for the battle frontier started in Pokemon emerald version.
OK, in emerald, Battle Tower is a part of the Battle Frontier. You can access it by beating the elite four. Scott takes you there.
Guess what you get a prize im not sure what but you also get to do something, if you mix records with an emerald version compete in the single battle portion of the battle tower and when you get to match number 7 look its you from ruby! Your name and your Pokemon are battling your emerald isn't that cool plus you will get to see what kind of trainer you are Example: Say you entered the latis and regirock and beat the whole battle tower in ruby when you mix records with emerald play emerald and you will battle those Pokemon you will be assigned a trainer so it will say ruin maniac ruby wants to battle or something like that.
Pokemon Ruby and Pokemon Sapphire do not have the Battle Frontier, instead they only have the Battle Tower. It was not until Emerald version that the Battle Frontier was added to the game.
The battle frontier after the Pokemon League.
battle tower
mirage tower or desert underpass
Battle Tower, if that's what you mean.
Rayquaza is at the top of Sky Tower, which is only in Emerald Version. You can only battle it on the 2nd visit to Sky Tower (as on the first visit, it goes to calm Kyogre and Groudon), and on the 2nd visit it's harder to go throgh the tower.
