The setting and story of
Omega Ruby and
Alpha Sapphire are largely the same as the original
Ruby and
Sapphire games. It begins with the player character riding in the back of a moving truck, who is relocating to the Hoenn Region from the Johto Region with their mother, as their father Norman has been hired as the Petalburg City Gym Leader. The player arrives with their parents at the family's new home in the village of Littleroot Town, on the southern edge of the main island. The player character begins their Pokémon Trainer journey by saving Professor Birch, the leading professor in the Hoenn Region, from a wild
Poochyena, choosing either
Treecko,
Torchic, or
Mudkip to defend him. Following the defeat of the wild Pokémon, the player receives the chosen Pokémon as their Starter Pokémon. The player then travels around Hoenn to complete the Pokédex and battle the region's eight Gym Leaders. Along the way, the player character encounters the antagonist group Team Magma in
Omega Ruby or Team Aqua in
Alpha Sapphire who wish to use the power of the Legendary Pokémon, Primal Groudon in Omega Ruby, and Primal Kyogre in Alpha Sapphire, to change the world to suit their desires. Team Magma wants to use
Groudon to dry up the oceans and expand the landmass, thereby allowing humanity to progress further. Meanwhile, Team Aqua wishes to summon
Kyogre to flood the lands and revert the world to a prehistoric state, which will allow Pokémon to live more freely. However, unlike in the original games, depending on the game version, Archie and Maxie will actually use the correct orb, leading to their Primal Reversions. With the help of Hoenn League Champion Steven Stone, and the Gym Leader Wallace, the player defeats their respective team and then either captures or defeats the Legendary Pokémon to prevent a global drought / heavy rainfall and thus ensuring the teams' mutual reformation. The player then advances on to the Hoenn League, challenging the
Elite Four and then the Hoenn League Champion, Steven, to become the new Hoenn League Champion. The player also has the option of participating in the various Pokémon Contests throughout Hoenn, using their Pokémon to put on a performance for an audience and judges. Aside from the gameplay, 20 new Mega Evolutions were added since
Pokémon X and Y, as well as "primal reversions" for Groudon and Kyogre, which function similarly. A new side quest is featured in
Omega Ruby and
Alpha Sapphire, called the "Delta Episode". The player must work with the new character, Zinnia, as well as Steven and Professor Cozmo, to find a way to stop a meteor from crashing into the planet. This also requires capturing the Legendary Pokémon
Rayquaza in order to stop the meteor that holds the Mythical Pokémon
Deoxys. == Release ==
