OMG! the fronteir brains are people you battle in emerald

[Lugialord]

The Frontier Brains are the people you verse when you battle a lot in a Battle Facility. There is one for all the 7 facilities. The Battle Pyramid's Brain is the hardest as he has the Regirock, Regice and Registeel although you have them, he does to.
