The protagonist of the Mega Evolution specials. He seeks out Mega Stones and trainers with Mega Evolved Pokémon to defeat them under the guidance of a mysterious voice on his Holo Caster.
- And Now for Someone Completely Different: He was notable for being the first special-focused character since Jimmy (Ethan's counterpart) who didn't have anything to do with Ash. However, unlike Jimmy, he later became a recurring character in the main series, ultimately becoming one of Ash's major rivals.
- Action Hero: Supremely so. His adventures in Hoenn and as an Unwitting Pawn of Team Flare pit him against some powerful opponents, and he finds himself in some dangerous spots, proving himself quite the badass in the process. Unlike the adventures of Ash and Co., the Mega-Evolution specials make no attempt to hide Alain is occasionally putting his life at risk, during his battles against Primal Groudon and Zygarde.
- With his Charizard they defeat a Mega Absol and a Mega Garchomp (despite a type disadvantage) with minimal difficulty, only being defeated by Siebold and his Mega Blastoise and putting up a good fight in the process. They later hold their own against Steven and his Mega Metagross in Act II of the Mega Evolution series.
- This trend continues in the third Mega Evolution Special, where they hold their own against a Primal Groudon and Primal Kyogre, although Mega Charizard ends up nearly dying trying to prevent Groudon from grabbing the Megalith.
- And now in Mega Evolution Special 4 he is the first trainer in the anime who isn't a champion or another member of the Pokémon League to defeat an Elite 4 member on-screen after he fought and defeated 9 other trainers with Mega Evolutions.
- He and his Charizard become the first opponents to defeat Ash-Greninja, which up until then dished out Curb-Stomp Battles like candy. It was a rather handy win, too.
- His Charizard does some serious damage against a 50% Zygarde before Mega Evolving using a well-placed Flamethrower and Dragon Claw. After Mega Evolving, Charizard proves itself to be able to give Zygarde its attention, matching it blow-for-blow without any signs of slowing down until Team Flare interrupts the fight. Granted, Zygarde may have been weakened beforehand a bit, but that's still a feat. And James gave Z2 a chance to recover using sunlight, so Alain may actually have gone toe-to-toe with Zygarde's full power.
- Always Someone Better:
- Played With and ultimately subverted. Alain has been victorious against Ash in three of the four battles they have had; two times in a one-on-one match and a third time during the Kalos League finals (with the remaining battle ending prematurely due to Ash collapsing from the strain of Bond Phenomenon). However, he is easily driven by guilt and his attempts to remedy the situation only make things worse thanks to Lysandre's teachings and orders. Alain doesn't find happiness until he meets Ash, whose battle prowess gives him a Worthy Opponent that Alain hasn't faced for a long time. It is Ash who snaps Alain out of his Heroic BSoD during the Team Flare climax, while also taking the power of Ash-Greninja to a whole new level. By the aftermath of Flare crisis, Alain begins to take notes from Ash's method of starting over again and privately sees him as the one trainer that he could not best.
- However, his Charizard can be safely said to fulfill this role towards Ash-Greninja.
- Audience Surrogate: For Pokémon's Periphery Demographic, specifically teenagers. Unlike Origins version of Giovanni, Alain's characterization doesn't focus on Pokémon nostalgia, but he's quite a bit older and more serious than the main episodes' child protagonists, and his partner Pokémon is Charizard, a fan-favorite with the Periphery Demographic. His mentor-student relationship with Mairin can be seen as an analogue to teenage and young adult Pokémon fans introducing their younger siblings to the franchise and teaching them how to play the games.
- Badass and Child Duo: He's the Badass while Mairin is the child.
- Badass Crew: Alain has an impressive line-up of Pokémon, which are Mega Charizard X, Metagross, Tyranitar, Weavile, Bisharp... and Unfezant.
- Big Brother Mentor: Reluctantly takes this role towards Mairin, but he ends up rejecting her out of fear she would get hurt following him. This backfires horribly.
- Big Damn Heroes: He saves Ash's Pikachu from Team Rocket, which is how he and Ash meet.
- Blood Knight: Alain challenges every Trainer who has a Mega Evolving Pokémon whenever possible. Or other tough trainers like Ash. It is shown that both Alain and his Charizard enjoy battling hard opponents.
- Butt-Monkey: In Mairin's Illustrated Mega Evolution Journal, Mega Charizard X gets its ass handed to basically every Mega Evolved Pokémon it battles. While we don't see the result of the battles, as it could easily have made a comeback, it is heavily implied that it has actually lost to a Mega Slowbro. It was also put asleep by a Mega Audino. The canonicity of these shorts, however, is unconfirmed.
- Brainy Brunette: Was formerly an assistant for Professor Sycamore studying Mega Evolution.
- Break His Heart to Save Him: Tells Mairin to leave him be and travel on her own, in rather harsh words, because he fears that she will get hurt travelling with him. This bites him in the ass as it sends Mairin in a depression, which gets worse when Chespie falls into a coma. Alain ends up promising himself to do anything to get Mairin to smile again.
- And he does the same thing with Prof. Sycamore. As Lysandre told him to keep things a secret in order not to sully the professor's name, Alain had been avoiding any confrontation with the professor. In the league, the two met, but Alain merely acknowledged Sycamore before leaving, not wanting to shake hands and leaving the sad professor.
- Break the Haughty: He almost suffers it when he sees Ash-Greninja's Giant Shuriken about to be launched during the League finals but is spared defeat when he manages to knock Ash-Greninja out first. But then it is Double Subverted when Team Flare attacks just as Alain is awarded the trophy of being the League victor, and he gets to see what his real reward is for becoming the strongest and helping Team Flare.
- Broken Ace: Alain is by far one of the strongest trainers in the Kalos region, able to consecutively win a gauntlet run of 10 Mega Evolution battles with Mega Charizard X and make up to the finals of the Kalos League with relative ease. But thanks to Lysandre's influence, Alain essentially cuts off contact with his friends in a misguided attempt to protect them, rarely feels any kind of happiness until Ash came along, and his goal to become the strongest is manipulated to help Team Flare's evil agenda.
- Broken Pedestal: Alain has a Heroic BSoD when Team Flare, and Lysandre especially, finally shows its true colors.
- Brought Down to Normal: After the Team Flare climax, Alain is no longer wearing the Mega Ring and Charizard no longer has the Charizardite X. In the last episode of XYZ, Alain reveals that he had turned them in to the police as they were properties of Team Flare and he wishes to no longer be associated with them. He plans to start from scratch and find his own Keystone and Mega Stone.
- Byronic Hero: He's always emotionally distant, has a pessimistic personality, pretty good looking for his age, is extremely passionate, is very good at what he does, and has numerous flaws that tend to drive the people he's closest to away from him while also making him very easy for villains to manipulate.
- Canon Immigrant: In Omega Ruby and Alpha Sapphire if the player has Steven's promotional event shiny Metagross in their party during a certain scene of the Delta Episode, Steven makes a nod to Alain and Act II, saying that a long time ago he fought against Rayquaza alongside a young trainer who used a black Charizard.
- Casting a Shadow: Half of Alain's team are part Dark-Type: Tyranitar, Weavile and Bisharp. Coincidently, they all have a secondary type that also makes them double weak to Fighting-Type moves, but that issue only comes to Weavile.
- Character Development: Alain was cold to anyone around him, minus Sycamore, and would distance himself from making friends as he believed they hold him him back from becoming stronger. However, after meeting and befriending Mairin, Alain began to question his beliefs as his friendship with her got to see a different perspective and mellowed his cold attitude a little. Once he meets Ash as both a friend and rival, Alain realized that being with Mairin did change him for the better as he made more friends that isn't her or Sycamore.
- Curb-Stomp Battle:
- His battle with Astrid and Mega Absol was one-sided in his favor.
- He gets handily beaten by Siebold and his Mega Blastoise, though Charizard does enough to impress Siebold making it more of a Curb Stomp Cushion.
- Heavily implied about all his Gym battles to enter the league in the span of 7 episodes.
- His first battle with Ash and Greninja is another Curb Stomp Cushion, with him on the giving end.
- His battle with Trevor in the Kalos League is also a curb-stomp in his favor. He only used Charizard to defeat all three of Trevor's Pokémon
- He basically pulls a Tobias in his battle against Remo in the Semi-Finals, defeating the latters' whole team with just Metagross and Charizard.
- Dark Is Not Evil: Three of his Pokémon are partial-Dark types, but Alain himself ultimately proves to be a good guy.
- Darth Vader Clone: Tetsuo Yajima has stated Alain was modeled after prequel-era Anakin Skywalker, being someone who turns to The Dark Side to protect those he loves.
- Deadpan Snarker: He snarks at Mairin's wording when she asks about Mega Evolution."Pokémon Mega Evolve, not people."
- Deconstructed Character Archetype: Alain's entire storyline essentially takes apart the goal of To Be a Master piece by piece. His total focus on becoming the strongest causes him to neglect the people important in his life and be an Unwitting Pawn for Team Flare. He believes that beating every strong trainer would make him stronger yet finds himself helpless when actual danger arrives. He stops enjoying his wins and never considers what to do after he became the strongest, his reasons behind it constantly changing to justify his path. And despite always winning battles, Alain finds himself feeling inferior to Ash Ketchum, who encompasses the happiness and wisdom that he never got under Lysandre's guidance.
- Defrosting Ice King: Even with his Sugar-and-Ice Personality in the Mega Evolution Specials, Alain was cold and stoic for most of the time. After he finally met Ash in the main series, Alain's personality has become friendlier and now he smiles much more often than before. That being said, he is still ice cold to people who aren't Ash and his friends, Mairin or Sycamore.
- Deuteragonist: Alain is arguably the closest the Kalos series has to one, being the focus of the Mega Evolution Specials and the primary rival of Ash in XYZ.
- Did You Just Punch Out Cthulhu?: During Act IV of the Mega Evolution Specials, Alain and his Charizard ran a gauntlet of facing 10 Trainers that wielded Mega Evolution and his final opponent is Malva of the Kalos Elite Four, where after a tough battle he won, being the first and only person outside of a Regional Pokémon League to beat a member of the Elite Four, when usually members of the Elite Four are whooping ass left and right like it's their day job.
- Dishing Out Dirt: Alain has a Tyranitar, which is primary a Rock-Type Pokémon, and it has the Sand Stream ability, which summons automatically a Sandstorm (and it's the first Tyranitar to display this ability in the anime). However, the Sandstorm vanishes when Pikachu splashes a lot of water. Aside from that, Tyranitar knows Stone Edge, and Metagross knows Rock Slide; the former is used defensively (and it backfires), while the latter is used offensively.
- Double Knock Out: His Unfezant ties with Talonflame when they collide into each other with Sky Attack and Brave Bird.
- Dramatic Irony: He keeps Professor Sycamore out of the loop because Lysandre tells him if the research on Mega Evolution is published then evil people will use it and ruin the professor's reputation. Knowing Lysandre's role in the games, he is one of those of people.
- Even more ironic is how his constant pushing of people is what leads them straight intro trouble and further fueling his goal to become stronger to protect them anyway, forever locking him in an endless loop. Failure Is the Only Option in his many cases.
- Easily Forgiven: Despite helping, albeit unwittingly, Team Flare capture Z2 and collecting the Mega Evolution energy that was needed to kickstart the Flare crisis, Alain is largely forgiven by Mairin, Sycamore, and Ash's group once he turns against Lysandre and saves Chespie from the Megalith Zygarde. Alain himself, however, views his contributions to be nearly unforgivable despite not knowing the full extent.
- Expy: In addition to the Darth Vader Clone entry above, he also has resemblances to N's original Pokémon Black and White videogame incarnation, moreso than the anime version of N, in terms of role. Like N, he's a pawn of a villain team who believes his talents are being used for benefit of many, and later encounters a trainer that intrigues him and challenges his views.
- Extra-ore-dinary: His Charizard knows Steel Wing, but seems to have forgotten it in favor of Thunder Punch. He is later on shown to own a Metang, a Steel-type that resembles a floating metallic robot, which later evolves into Metagross, a Spider Tank. He also has a Bisharp, and his Unfezant also knows Steel Wing.
- Find the Cure!: His motivation at the end of the Mega Evolution specials to cure Chespie from his Zygarde-induced coma, leading to his appearance in the main anime.
- Final Boss: He's Ash's final opponent in the Kalos League, with the battle ultimately ending in a win for Alain.
- Finishing Move: His Charizard ends most battles with Blast Burn.
- Foil: He and Ash contrast each other on many things.
- Ash is a Keet, while Alain is The Stoic. Also, Alain isn't keen on making friends but will give good, logical advice. Ash is a people person and gives more abstract life lessons.
- Both have a Charizard, but use them in different ways. Alain specializes in his and puts it in the front of his team. Ash puts his behind in the reserve spot so that he can train the other, lesser-experienced Pokémon.
- In the league, Ash uses primarily Kalos-origin Pokémon barring Pikachu, his ace. Alain uses Pokémon from all generations, one of each (except for Unova which has two)* . His ace, Charizard, has a Super Mode that originated from Generation VI.
- His team focuses on raw power in comparison to Ash who prefers speedy Pokemon. Even his tactics are feats of strength compared to Ash who prefers misdirection and indirect tactics.
- Foreshadowing: Ash telling him about the strong Pokémon Trainers in the Kalos League hinted that Alain would enter it as well, due to his Blood Knight nature. And he does eventually get eight badges seven episodes later.
- Friendless Background: Alain didn't have any other friends that weren't Professor Sycamore as his loaner attitude distanced himself from making them. However, after meeting Mairin and Ash, Alain not only found his first real friends from them but also discovers the true meaning of it.
- Friendly Rivalry: He and Ash have a friendly relationship with each other from the beginning, which makes him different from the previous main rivals (Gary, Paul, Trip) who were very antagonistic towards him. Since Alain has met Ash, he has become a Defrosting Ice King.
- Gentle Giant: Outside of battles, his Charizard is rather friendly and a bit cheerful. And it isn't particularly aggressive.
- Ground Punch: His Charizard does this to perform Blast Burn.
- Guilt Complex: His Fatal Flaw. Alain tends to shoulder the responsibility upon himself whenever those close to him are in danger or at the risk of being in danger. This makes it easy for Lysandre to manipulate him into helping Team Flare's agenda, such as collecting Mega Evolution energy in order to "save" Mairin's Chespie and not telling Prof. Sycamore about their operation to "protect" the professor's reputation. It also makes Alain very susceptible to suffer Heroic BSoD whenever a large crisis breaks out such as Team Flare's attack on Lumiose City. Alain has a nearly unbeatable Mega Charizard X, is the only one who could fight Lysandre (with Ash and his Pokémon incapacitated by Flare cuffs), and now sees Lysandre's true intentions. But instead of fighting his former boss, he completely breaks down in despair due to the guilt of unwittingly endangering everyone. He remains in this state until Ash breaks free of his bonds and tells him to not dwell on past mistakes.
- Heel Realization: He had absolutely no idea what Lysandre was actually planning and completely broke when he found out (though he recovered long enough to help Ash and the others fight back).
- Heroic BSoD: He doesn't take the revelation of Flare's true purposes very well. Also, Alain thought his actions caused his friendship with Mairin and Ash, due to pushing her away and being force to let Team Flare take him along with his Pokémon captivate. However, Alain snaps out of this when Ash not only talk some sense into him but also assure them that they're still friends despite everything he did, which got him to realize the true meaning of friendship.
- I Am Not Left-Handed:
- In a sense, his Charizard. He Mega Evolves his Charizard most of the time, but it is more than capable of kicking ass without doing so. Ash's Greninja and Zygarde learn this the hard way in different battles. During the Kalos League Semi-Final, it inflicts a Curb-Stomp Battle on a Rhyperior.
- He also isn't purely dependent on his Charizard to defeat strong trainers, as his Metang is strong enough to defeat Ash's Noivern, which had previously taken on a Legendary Pokémon and nearly won. It later evolves into Metagross.
- During the final match, Alain sends out Charizard to fight Pikachu, even though he still has Bisharp left, which surprises Ash's friends in the audience who don't expect Alain to send his ace out so soon. It shows that he is playing safe and doesn't want to lose yet another Pokémon to Pikachu, so he prefers choosing the one member that he can always rely on, rather than the other remaining member that is already damaged.
- Icy Blue Eyes: Representing his cool, collected personality. Also to match his black and blue Mega Charizard X motif.
- In the Name of the Moon: "Key Stone, respond/listen to my heart. Beyond evolution — Mega Evolve!" The word order slightly changed in the 2nd special.
- Invincible Hero: He is currently the only major rival whom Ash faced multiple times and never defeated.
- Irony: In search of and defeating various Mega Evolutions, Alain sees the greatest challenge that he and Charizard are looking for is in a Pokémon that doesn't have a Mega Evolution (although it is still a Super Mode all the same).
- It's All My Fault: Blames himself heavily for Chespie's comatose state. In fact, Alain's tendency to blame himself for everything that has happened is his Fatal Flaw as it prevents him from taking action against Lysandre despite becoming the "strongest" in the League. It only took Ash giving an inspirational speech and freeing himself to snap him out of his depression state then fight Team Flare.
- Jerk with a Heart of Gold: Genuinely means well for the most part. He mainly assists Lysandre because he believes Lysandre will use the Mega Evolution energy for peaceful purposes.
- Large Ham: Not him, his Charizard. Much like Ash's Charizard it'll let out a mighty roar when entering a battle, in fact the roar is mightier depending on the opponent. When Mega Evolution it'll let out an even louder roar that gets deeper as it mega evolves.
- Lightning Bruiser:
- Charizard is quite fast, is pretty tough and is very strong.
- Metagross hits hard, can take a lot before it goes down and it moves really fast with Agility. Although, it is not as tough as Charizard.
- Made of Iron: Charizard has become extremely tough, to the point that taking Pikachu's and Greninja's super effective moves and Ash-Greninja's giant, orange Water Shuriken are not enough to take it down.
- Mighty Glacier: Tyranitar usually hits hard, but is too slow to actually land a proper hit.
- Motif Merger: His team is comprised of Pokémon from Generation I to Generation V, and one could argue Mega Charizard X represents Generation VI.
- Motive Decay: His original goal, as Sycamore's assistant, was to find a Mega Stone and study its properties to better understand Mega Evolution. But soon, he encounters Lysandre, who twists the goal into a standard To Be a Master scenario where becoming the strongest would somehow make his dreams come true. Alain buys it and seeks to become the strongest Mega Evolution trainer, but then has trouble figuring out why does he want to become the strongest. It notably fluxes between understanding Mega Evolution to being able to protect his loved ones to finally simply seeking the thrills of battles.
- Must Make Amends: Alain thought by helping Lysandre would make amends with Mairin for pushing and being harsh with her. After being forced to let Team Flare take Ash prisoner and realizing that they took advantage of pushing Mairin away, Alain felt that he made things worse and believed that can't fix his actions. However, through some words of encouragement, Alain realized that it isn't too late to fix his mistakes as he truly did make amends by recusing Ash and Mairin's Pokémon.
- My God, What Have I Done?:
- In Pokémon: Mega Evolution Special IV: Alain became gilt-ridden when he discovered Mairin's Chespin fell into a coma as he kicked himself for pushing his best friend away.
- In A Towering Takeover!: Alain had this reaction when he was forced to let Team Flare take Ash and his Pokémon captivate. He was also suitably horrified and ashamed when he discovers Lysandre's real intentions.
- My Greatest Failure: For unwittingly helping Team Flare devastate Lumoise City and bring the greatest crisis upon the Kalos region. Even after turning against Lysandre and saving Chespie from the Megalith Zygarde, Alain never forgives himself for his contribution to the whole mess. He gives up the Mega Ring and Mega Stone provided by Lysandre in order to start his life over with Mairin and Sycamore again.
- Nice Guy: This guy is quite a selfless person who treats his Pokemon well, ditches his aloof behavior later on to open up to more people like Ash as he becomes completely polite to Ash without being rude to him a single time with strong respects and willing to help everyone like Professor Sycamore with research into the Mega Evolution.
- Nice Job Breaking It, Hero!: Alain helping out Team Flare throughout the saga proves to be disastrous when Lysandre decides to launch his attack on Lumiose City after the League. And he couldn't have done it without Alain collecting the Mega Evolution energy for him as well as securing the capture of Z2.
- Not So Different: Alain and Ash were quite similar in the beginning about making friends as they wanted to travel alone with just their Pokémon. However, after meeting their best friends and traveling companions, Alain and Ash realized how wrong they were about making friends as they had their opinions changed.
- One-Hit Kill: His Bisharp knows the OHKO move Guillotine. It knocks out both Hawlucha and Goodra with it.
- Our Dragons Are Different: Mega Charizard X's secondary type. He mocks his opponent Remo, a Dragon specialist, for not knowing that Mega Charizard X's typing is Fire/Dragon. Due to this, Charizard loses its Water-Type weakness, making him more resistant to said moves.
- Paper Tiger: His two pseudo-Legendary Pokémon, Tyranitar and Metagross, don't get a single win against any of Ash's Pokémon and both of them are knocked out by Pikachu. Tyranitar even gets it worse than Metagross, since the latter at least has an on-screen victory as a Metang and it got plenty of off-screen victories in the league. Tyranitar barely gets a hit on Pikachu, while Metagross does some major damage at least and it takes a lot to go down. Tyranitar is defeated in a faster fashion.
- Playing with Fire: Alain has his Charizard since it was a Charmander. During his journey, when he met Lysandre, his Charmander had since evolved into a Charmeleon.
- Pyrrhic Victory: Alain finds both his quest to prove his Charizard is the strongest Mega Evolution and his later victory over Ash at the Kalos League to fall into this when Team Flare stages their attack on Kalos. By end of the arc, after everything has wrapped up, Alain considers Ash to be the stronger trainer despite Alain having previously beaten him.
- The Rival: He becomes one to Ash. After Ash tells him that there are a lot of other powerful trainers and Pokémon in the Kalos League, Alain quickly gathers eight badges, enters it, and wins it as well, mostly to fight Ash in the league again. He quickly becomes Ash's strongest Kalos rival.
- Savvy Guy, Energetic Girl: The savvy guy to Mairin's energetic girl.
- Scissors Cuts Rock: Charizard is not only relatively resistant to moves that are super effective against it, it has defeated several Pokémon, which are normally resistant to Fire-Type moves, with its Fire-Type moves.
- Shock and Awe: His Charizard knows Thunderpunch to counter Water-Type Pokémon, and his Bisharp knows Thunder Wave to slow down the opponent.
- Signature Move: Charizard's Dragon Claw is used more often than any of its other moves, even Flamethrower. On this note; most of his moves are physically oriented, as he tends to mega evolve his Charizard to the more offensive Charizard X; the abilities are logical.
- The Stoic: He's very serious and mature, and rarely smiles.
- Sugar-and-Ice Personality: Discussed by Mairin who points out that he's intimidating but really cares about Pokémon and is supportive of her.
- Super Mode: His Charizard can Mega Evolve into Mega Charizard X. He also seeks out other trainers with Mega Evolutions to beat them.
- Surveillance as the Plot Demands: Seems to be unaware that Lysandre is observing the power of his Charizard when they Mega Evolve and battle. In Act II, it's revealed that Lysandre is the one who provided Alain with the Mega Ring and Mega Stone, in return for Alain's aid to gather data for his research.
- Took a Level in Cheerfulness: Alain finally smiles and becomes more open after he goes through heartbreaking times when his aloof behavior made it worse for Mairin when her Chespin accidentally ends up in the coma making himself self-doubted when he meets Ash and his friends. He treats Ash with strong respects for each other without being rude to him a single time calling him a great opponent to battle. After Ash consoles him that it wasn't his fault, he decided to help Professor Sycamore to research mega evolutions and resolves to find the keystone for himself and the mega stone for his Charizard to call upon the mega evolution himself.
- To Be a Master: Sort of, he never calls his goal such but he does seek to beat every Mega Evolved Pokémon out there.
- Training from Hell: After returning from their adventures in the Hoenn Region, Alain and Charizard spend all their time training at Lysandre Labs, and eventually the results show as they are capable of defeating 10 Mega Evolution trainers back-to-back, the final one being an Elite Four member.
- Transformation Trinket: A Mega Ring for him and an armored collar for his Charizard to hold its Charizardite X.
- Uncatty Resemblance: His outfit resembles Mega Charizard X in color scheme and his scarf resembles the wisps of flame coming from Mega Charizard X's mouth.
- Unwitting Pawn: Worked with Lysandre not knowing his true intentions.
- Victory Is Boring: Despite his sudden interest in participating in the Kalos League, it becomes apparent that Ash is the only person Alain is actually interested in facing. Alain treats all his other opponents like they are a distraction.
- Was It Really Worth It?: Alain seems to have finally achieved his goal of becoming the strongest Mega Evolution trainer by defeating Ash and Ash-Greninja (his toughest opponent yet) at the Kalos League finals and making Mairin smile. Shortly after winning however, his boss Lysandre launches an attack on Lumoise City with Zygarde, putting everyone in danger, Mairin included. Later, Lysandre reveals to Alain that the whole point of becoming the strongest was to simply collect Mega Evolution energy to bring Zygarde under their control and be worthy of living in his post-genocide world. He rhetorically asks Alain if he had ever thought of what exactly he was going to protect with the strength he had gained. This breaks Alain completely.
- What the Hell, Hero?: Gets a disapproving grunt from his own Charizard in response to driving away Mairin.
- Worthy Opponent: His rematch with Ash and Greninja fills him with an excitement he hasn't felt in many matches. After Greninja gets a few good hits in, he even calls Greninja worthy to face Charizard's Mega Evolution. He ended up enjoying the battle so much that he decided to quickly gather 8 badges so that he could have an opportunity to face off with and defeat Ash again in the Kalos League.

A Dragon-Type specialist introduced in Mega Evolution Special I. He was ordered by somebody to look for the Mega Stone that was found by Alain and they battled over it, with Remo on the receiving end. He uses a Mega Garchomp.
- Boisterous Bruiser: A loud trainer boasting about his powerful Dragon-Type Pokémon and he likes doing poses.
- Curb-Stomp Battle: Come the Kalos League Semi-Finals, Alain defeats his whole team using just his Metagross and Charizard, and Charizard didn't even have to Mega Evolve until its battle with Garchoo.

Steven Stone (Daigo Tsuwabuki)
The Hoenn League Champion, whom Alain and Mairin meet during a trip to Hoenn. Aside from being a powerful trainer, he is also an expert when it comes to the various types of stones in the Pokémon world.
He originally used to be a One-Shot Character in Advanced Generation, but we got to see more of his character in XY.
- The Ace: Being the current Champion of the Hoenn Region and the son of the Devon Company's president, he automatically qualifies as this.
- Always Someone Better: Other than Siebold and his Blastoise, Steven is the only shown Mega Pokémon owner who breaks Alain's victory streak. His Metagross endures all of Charizard's attacks, even the super-effective Blast Burn, without any visible damage and lays down some serious hurt on him. If not for Pyroar interrupting the battle, it's safe to assume he would have won.
- Ascended Extra: He was first mentioned in passing in the Advanced Generation series, and when he finally showed up, he was ultimately just as a One-Shot Character with little fanfare. For the XY series, he's acknowledged as the Hoenn Champion, becomes an important character in the Mega Evolution Specials, has a part in Sawyer's backstory, and eventually returns for the conclusion of the Team Flare saga.
- Back-to-Back Badasses: With fellow Champion Diantha when buying more time for Ash and Alain to defeat Megalith Zygarde.
- Badass Baritone: In his original appearance when he was voiced by Rintaro Nishi, he had a very deep voice that underlined his "experienced adventurer" trait. With the change of his seiyuu, this trope is no longer the case and his voice sounds much higher and younger and fits his gentleman and Bishounen character.
- Beware the Nice Ones: During his original appearance, Steven got really angry when Team Rocket harmed a herd of Aron, sending his Aggron to blast them off really hard.
- Big Brother Mentor: He had shades of this in his original appearance with his little interactions with Max, it's played much straighter with his relationship with Sawyer. Steven gave Sawyer the items he needs to Mega Evolve his Sceptile and Steven has recruited Sawyer for his expeditions where the latter can learn from the experience.
- Big Damn Heroes: Shows up to save the heroes during their raid on Lysandre Labs.
- Bishounen: He was always good looking, but it's his reappearance in the XY Saga where his handsome look is acknowledge in-universe.
- Brick Joke: Jessie was instantly smitten with Steven merely from seeing a photo of him in Sawyer's notebook. An infatuation that suddenly resurfaced out of nowhere when Team Rocket and the twerps run into the real deal much later.
- The Bus Came Back:
- Chrome Champion: Steven's Metagross is a shiny variant, the silver (body) and gold (its "cross") color better alluding to its metallic structure.
- Mythology Gag: Steven gave Sawyer a Key Stone and a Sceptilite. In the ORAS games, Steven gives the player character the Mega Evolution items as well.
- One-Shot Character: In his debut in the Advanced Generation series.
- One-Man Army: His Metagross tears through Lysandre Labs effortlessly, despite being heavily outnumbered.
- Super Mode: His Metagross can Mega Evolve into Mega Metagross.
- Took a Level in Badass: Sometime in between the Wallace Cup arc of the Diamond and Pearl series and the XY series, Steven became the Champion of the Hoenn region.
- Since the XY version of Steven is based off of his appearance in ORAS, it's possible that he was already Champion at some point, but passed off the title to Wallace like he does at the end of that game so he could focus on archeology. He then just took back the title later.
- You Gotta Have Blue Hair: He has light blue hair in both series he has appeared in.
