The Rise of Team Flare- The Kalos Champion
Shortly after the player arrives in Kalos, he/she finds three people waiting. They introduce themselves as Trevor, Tierno, and Calem (If the player is female)/Serena (If the player is male), Pokemon Trainers from Kalos. They encourage the player to meet Professor Sycamore again, but this time in the Pokemon Lab in Lumoise City. The player also meets his/her brother again, who gives the player a free Charmander/Squirtle/Bulbasaur he breeded.
In the lab, the Professor congratulates the player and gives him/her a Poke Radar along with the National Pokedex. The Professor also tells the player that the Kalos region also has a Pokemon League and challenges the player to defeat the Champion. However, the Professor recieves strange radio signals somewhere in the west side of the region, asking the player and Calem/Serena to investigate. When they get there, the two discover that the signals are coming from Geohenge Town and head over to see what's going on.
At Geohenge Town, the two are shocked to discover the giant hole in the middle of the town opened. Calem/Serena tells the player about the ultimate weapon Team Flare activated three years ago before the two carefully head down into a secret facility, or the Ruined Team Flare HQ.
In the HQ, the player and Calem/Serena spilt up to find out what's going on. The player finds a strange room that is still somewhat covered in rubble. Xerosic then arrives and explains that a man named Lysandre tried to use the weapon but is still trapped. The two fight once more before Calem/Serena runs into the room. Xerosic then activates a machine that clears the rubble. A man then climbs out of a hole, revealing himself to be Lysandre. Lysandre challenges the player to a fight, and Lysandre loses. The two villains manage to escape before AZ enters the room, saying that he was the one responsible for the ultimate weapon and apologizes before the three exit the HQ.
After the player has won all eight Kalos Gym Badges, Lysandre makes a public announcement on the Holo Caster saying that he will use Xerneas' and Yveltal's power to eliminate "the filith of this world". The Professor traces Lysandre's location to the Legendary Peaks, a place where Xerneas and Yveltal were said to be born according to Kalos myths. After arriving to the top of the peak, Lysandre and Xerosic are seen summoning Xerneas and Yveltal. Xerosic notices the player and holds them off, but is ultimatly defeated. However, it is too late, as the two Legendary Pokemon are by Lysandre's side. Luckily for the player, Trevor, Tierno, Calem, Serena, and AZ arrive to help. Unfornatly, Lysandre creates a mystical barrier behind the player, eliminating any help.
After one final battle between Lysandre and the player, Calem (if the player is male)/Serena (if the player is female) is the first to notice the barrier is broken and approces Lysandre. The villian, in a desperate effort, attempts to use Xerneas and Yveltal, but their power backfires, warping Lysandre into an alternate dimension. Xerneas and Yveltal flee, leaving the six alone in the peaks. Xerosic then turns himself in, saying that there's nothing left for him to do.
After the player has defeated the Elite Four, Calem (if male)/Serena (if female) reveals him/herself to be the Kalos Champion. After one last fight, the player becomes the Kalos Champion as well as the Ampardo Champion. The Professor invites the player to a parade, just like Calem/Serena. With that, the game's story finally ends.
