Shortly before approaching the town of the first Gym Leader, the protagonist first encounters the Team Magma/Aqua in the Petalburg Woods, where he or she rescues a worker from Devon (a company that manufactures Pok?balls) and recovers Devon merchandise.[21] Upon arriving in Fallarbor Town (after defeating the third Gym Leader), the protagonist discovers that Professor Cozmo, an astronomer, has been kidnapped by Magma/Aqua. The protagonist traces them to a cave, Meteor Falls, but is too late to stop them from escaping to Mt. Chimney with a meteorite. The protagonist follows Magma/Aqua to Mt. Chimney where they are preparing to use the meteorite to alter the climate of the region. The protagonist defeats the Team's leader, however, and returns the meteorite to Professor Cozmo.[22] Shortly after the protagonist defeats the fifth Gym Leader (the protagonist's father, the first time such a character appears), Magma/Aqua again attempts to change the region's climate by stealing a Castform, a Pok?mon with the ability to change the weather, from the Weather Institute.[23] After the protagonist defeats the sixth Gym Leader, Magma/Aqua steals an orb with the ability to control a legendary Pok?mon (Groudon in Ruby, Kyogre in Sapphire). Magma/Aqua then steals a submarine from Captain Stern in Slateport City; the protagonist, however, infiltrates the team's hideout, but fails to prevent the submarine from being used. Magma/Aqua, then travel with the orb to the Seafloor Cavern, where Groudon or Kyogre resides; the team then uses the orb to awaken the legendary Pok?mon, but they have chosen the wrong one and have instead enraged the Pok?mon instead of putting it under their thrall. Once awakened, the Pok?mon travels to the Cave of Origin and causes a region-wide drought (Ruby) or severe rainstorms (Sapphire). When the protagonist defeats (or captures) the Pok?mon, the region's weather returns to normal.[24]
But I'd be interested to see if they include any non-gen3 legendaries, they added a lot in HGSS
