All the time legendaries are your best bet the ones you can use are: Articuno, Moltres, Zapdos, Raikou, Suicune, Entei, Latios, Latias, Registeel, Regirock, Regice. For the battle factory choose level 100 and look for Pokemon that have moves that will give them the edge over your opponents type wise or move wise its all strategy in the factory you can swap Pokemon with your foes by the way do so if needed to really nail the frontier brain for the other facilities bring the Pokemon i mentioned above you should be fine.
if you where me I would go to the arcade star in hg ss
in rse i never played same for diamond and pearl the arcade star is the one you should do
you have to battle 50 trainers for the first battle, and 170 trainers for the rematch with the frontier brain argenta
if you win streak at 21 and you need a leendary because he only use some legendary pokemons (sometimes)!!!!!!!!!!!!!!remember!only just 50 percent from frontier brain nolland because nolland is strong so good luck.....it helps just do that instruction so you can win like in easy ways
Go to the Battle Frontier and defeat 7 trainers in a row*. When you defeat them you will earn Battle Points (B.P.). The amount of B.P. you earn is based on the facility you enter. If you beat the Frontier Brain (after beating 21 trainers in a row and then 49*) you get a lot more B.P. *On some facilities like the Battle Hall, you need to beat 10 trainers to get B.P. and beat 50 and 170 trainers in a row to face the Frontier Brain.
As you get through the battle frontier you receive Battle Points, these points allow you to get items that are very hard to find in the game, you may exchange your points at the battle shops in the battle frontier area.
It's in the Fight Area. You have to beat the Elite Four first. Then mom will say your rival wanted you to meet him at the fight area. Go to Snowpoint City and take the ferry. When you get off your rival will be standing there and take you to the entrance of the battle frontier. But the entrance is blocked because Flint and Volkner are standing there. They'll battle you to see if you're tough enough for the battle frontier. Beat them and you will be able to go into the battle frontier.
you have to beat the battle frontier brain
you have to battle 50 trainers for the first battle, and 170 trainers for the rematch with the frontier brain argenta
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)
You can't
yes
First you complete both options in the battle places ( e.g. battle dome/pike/arena/pyramid etc) like in the battle dome, there is level 50 and open level. first you do level 50 then open level, and then you should see the frontier brain, if not try any option again, and then hopefully you should be able to see/ battle them.
No, but the Frontier Brain of Sinoh is there as an Elite Four member.
The blue guy i think
You get a Symbol by beating one of the Frontier Brains, the bosses of the different facilities at the Battle Frontier. Once you win enough battles in a certain facility, the Frontier Brain there will challenge you. If you win the battle, you will get a Silver Symbol. Beat that Frontier Brain again and you get a Gold Symbol. You can get two Symbols (silver & gold) for each of the facilities in the Battle Frontier.
Each facility in the battle frontier has a frontier brain to challenge them beat each facility 3 times in a row the next time you get to the 7th trainer it will be the frontier brain.
LOOK! the only way to battle a frontier brain is to beat the challenge and get bp 5 times!
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
