you have to see all 210 Pokemon in the game before unlocking that area.
AnswerIn the battle zone there are 3 areas. The Fight Area,The Survival area and the resort area. When you go to the battle tower in the fight area, that and the survival area are for training. The Resort Area is (I think) Where your Pokemon get massaged. Wrong that's all wrong the battle zone is the zone to battle duh!
After you beat the Pokemon league and get the National Dex, you will be able to get to the Battle Zone. The battle zone is comprised of 3 areas: the fight area included. The fight area is basically a place to test your skills as a trainer as you strive for the top of the battle tower.
The Fight Area can be accessed by defeating the Elite Four, and then traveling to Snowpoint City. From there you can talk to a Sailor and he will take you to the Battle Zone.
He returns to the battle zone in the fight area
The battle factory is at the Fight Zone.
In diamond and pearl he will battle you in the fight zone on certain days of the week, in platinum, he will be found in the survival area on certain days
He is on the survival area, battle him in saturdays and sundays.
I think you are mixing up the battle area with the battle frontier at fight area. That's my answer
Finish your pokedex.then go to prof. rowan and talk to him.Then prof oak will walk in and give you a national pokedex.Go back to the battle zone and they will be gone.BEWARE:people who want to battle you past the battle zone will have lv.50-52 pokemon.
if you have beaten the league then on diamond/pearl he is every saterday and Sunday at the battle zone and on platinum he is at the survival area just next to the town center that too is each Saturday and Sunday
