You'll encounter two organizations in Hoenn that are in a struggle for control: Team Magma and Team Aqua. Each of them has a boss who leads the group. Serving the boss are two Admins, male and female, and below the Admins are the many Grunts who carry out the day-to-day labors of the team on the ground.
In Pokémon Omega Ruby, Team Magma will seize more power to achieve its goals. Team Aqua plays the more prominent role in Pokémon Alpha Sapphire. In both versions, you will find yourself drawn into the conflict!
