Pokemon Battle Revolution is a game that focuses on online battles and does not allow players to capture or train Pokemon. It uses data from your Pokemon Diamond, Pearl, or Platinum game to allow you to battle with your Pokemon online.
To get an Infernape in the main Pokemon games, you need to evolve Chimchar, which is a starter Pokemon in Pokemon Diamond and Pearl.
Here's how you can get Infernape in those games:
1. Choose Chimchar as your starter Pokemon in Pokemon Diamond or Pearl.
2. Level up Chimchar to level 14 to evolve it into Monferno.
3. Continue leveling up Monferno to level 36 to evolve it into Infernape.
