In Generation IV, you battle Palmer the first time on your 21rst win streak (which means you win twenty one battles in a row without losing. Battles occur in seven battle segments.) If you continue your streak all the way to 49, you'll get challenged by Palmer again.
You get 20 BP for beating a Brain.
This goes for all the other places- Battle Castle, Battle Hall, Battle Factory, Battle Arcade.
As for Gen III, I've no idea, you're on your own, buddy.
The blue guy i think
to get a symbol go to a place like the battle tower (or any other place) and keep winning and winning and winning until you get to battle a frontier brain and do this with all of the battle frontier buildings
you have to beat the battle frontier brain
It is very simple. Challenge each battle frontier building and win three times in a row and on the 7th battle on your third challenge someone will tell you that the frontier brain of that facility will want to challenge you. ( You have no choice but to battle them)
The Battle Tower is in the Battle Frontier, which is north of Route 40.
U Find Him At The Battle Tower Located In The Battle Frontier
