Once again you must stop Team Magma or Team Aqua from expanding to keep balance in the world of Hoenn. Rayquaza (sky) will help you to balance out Groudon (ground) and Kyogre (water). You will train to fight seven new Frontier Brain competitors to obtain all of the needed symbols in the Battle Frontier.
