defeat the pokemon league
We can get other regions starter Pokemon if we defeat the battle tower
You can get it at the Battle Tower
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.
Only the trainers in battle tower (the battle tower trainer's Pokemon will not be recorded in the pokedex)
doesn't exist. only battle tower.
There is no Trainer Tower in Pokemon Pearl. It is only present in Pokemon Leafgreen and Firered and Pokemon Emerald. There is however, a Battle Tower in Pokemon Pearl which is basically the same as the battle towers in Pokemon Ruby, Sapphire, and Emerald.
You Can't Clone On Pokemon Ruby/Sapphire. Only Emerald In The Battle Tower.
beat it again. nothing will happen
=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.=
From what I've heard, you have to transfer it from Pokemon: Battle Revolution for the Wii.
By a glitch at the battle tower in the frontier after you beat the Pokemon league
you train your pokemon i guess. Not much to do after that.
