Alain

He is Ash's main rival in the Kalos region, and the eventual Kalos League Champion after defeating Ash in the finals. Alain is a tall, slim teenager with messy, black hair and blue eyes. He typically sports a pair of baggy, grey pants, a black, leather jacket, black boots, a blue shirt with a white undershirt and a pair of fingerless gloves. He also wears a pale, blue scarf that closely resembles the flames that appear from Mega Charizard X's mouth. Alain is a calm, silent-type figure, who shows little emotion and focuses his attention towards battling. Deep down, however, he does not wish to see the ones closest to him to suffer or get them in danger. Alain also obeys Lysandre's orders without much hesitation, since Lysandre was the one that equipped him with the Mega Ring and gave the Mega Stone, Charizardite. In addition, Alain despises losing (at the time of being defeated against Siebold), hence why he did ask Lysandre to battle 10 Mega Evolution trainers to become stronger. Also, he doesn't show much happiness to most victories, but he does anticipate battling Ash. When Team Flare began their assault on Lumiose City, Alain felt betrayed by them and became extremely upset at the fact that he had been used by them. Those feelings led Alain to turn against Team Flare and join Ash's battle for the sake of the world.

After Team Flare's ambitions were finally stopped, Alain felt depressed at what had happened and thought that he still needs to atone for the mistakes he made now that everyone is safe. However, he started to feel better after a brief conversation with Ash and gladly accepted Sycamore's offer to become his assistant again. Alain is a Pokémon trainer, who, before his quest to search for Mega Stones, worked with Professor Sycamore in his lab in Lumiose City. Sycamore knew there were secrets tied to the Mega Evolution and let Alain go pursue the quest of finding the Mega Stones.[1] One day, Alain found an injured Gible, which Sycamore adopted and took care of, even managing both of them to befriend Gible. Alain and Sycamore watched as Gible evolved into a Gabite and later into a Garchomp.[2] Mega Evolution Act II 11Sometime after, Alain went to his quest. Alain came to a ruin to find his first Mega Stone, but it was taken by a man named Lysandre. Lysandre showed Alain the Mega Stone, claiming Alain can become even stronger. Alain did not trust him at first and had Charmeleon attack Lysandre's Pyroar, but Charmeleon was knocked out. Alain saw some wisdom in Lysandre's words and accepted his proposal, taking the Key Stone and Charizardite, which allowed Charmeleon, once it'd evolve into a Charizard, to Mega Evolve.Alain and his partner Pokémon, Charizard, travel Kalos in search of other trainers capable of Mega Evolution to battle with.

During a battle with Astrid and her Mega Absol, Alain is discovered by a young trainer named Mairin, who is intrigued by his ability to Mega Evolve Charizard. Despite his initial protests, Mairin follows Alain as he continues his journey in order to learn more about Mega Evolution. Alain soon grows to care for and respect Mairin, coaching her as she learns about Pokémon and watching out for her physical needs. Mairin saw Alain had a Key Stone, using it in battle against Remo and his Garchomp. Alain instructed Mairin how to catch a Flabébé. Afterwards, he came to a restaurant, where he met Siebold and had a battle with his Mega Blastoise. Despite losing, Alain was told he did well, since Siebold is a very tough opponent.After arriving in the Hoenn region and meeting Steven, Alain has a battle with the Hoenn Champion. However, the battle is interrupted by Lysandre, for he also came to Hoenn to show a part of a slab, which tells about a mysterious stone that Lysandre has been searching for. Together with Steven's part of the stone, Lysandre activated a portal, showing a path to a temple in the sky, which the group, including Alain, went to. They found a mysterious rock called the megalith, which was supposed to be connected to Mega Evolution. Before Lysandre's team could properly study it though, Mega Rayquaza appeared and attacked them. Alain is injured while protecting Mairin from Mega Rayquaza's Draco Meteor, and the megalith vanishes. Lysandre saw the megalith's energy was emitted close to Rustboro City and sent Alain to accompany Steven to find the megalith.
