#regitrio

Steven's fight is forgotten in nuzlockes (the most popular way to see old gen pokemon gameplay), and I still didn't challenge it, because the regis are still BABIES (lvl 42 compared to rayquaza's lvl 75).

And the battle frontier is the most fun place there is. You have 7 gamemodes, and each is unique. You have a dungeon crawler as pokemon (This is the official gamefreak design. You can have fun after you beat the elite 4), pokemon but their natures control them (this one sucks), Tournaments, their own version of the elite 4 (the 7 'brains' of battle frontier), and a secret (?) final boss.

After you beat Wallace, Proffesor upgrades your pokedex into the national mode, so you can register pokemon from other games. You also immediately get to choose between latios and latias right after you 'finished' the game.
