Team Magma & Aqua
Just as in previous games, Pokémon Omega Ruby & Alpha Sapphire puts you up against an antagonizing gang of thugs who want to use Pokémon to meet their goals. Like before, you have to face Team Magma or Team Aqua, depending on the version. They either want to use Groudon to expand the land masses to give more room for land Pokemon, or use Kyogre to expand the oceans to give more room for sea Pokemon. In both cases the opposite team serves a supporting role to you in the story.
Depending on the version, the teams use different Pokemon. In the case of Team Magma, they use more Ground or Fire-types such as Numel. In the case of Team Aqua, they use Water-types like Carvanha. Both teams use certain Pokemon though, like Zubat.
