Misty was in Kalos to watch Ash Greninja which was a legendary transformation of Greninja and she wanted to see the finals with Ash vs Alain. Misty has always wanted to go to Kalos region and travel in Kalos and she recently got a vacation.
Misty was near the airport and then waited in the taxi stand near the airport. Misty soon saw a taxi come and then Misty entered the taxi and then said "I would like to go to Lumiose Stadium!" and then entered the taxi. The taxi soon started and then Misty saw the scenery of Kalos which had a tall Prism Tower.
Misty looked at the highway as the car travelled rapidly in the highway. The car then turned and then reached the roads. Misty saw the car travel through the roads and saw many concrete buildings which had less height. The car soon reached Lumiose Stadium and then Misty paid money and then left the car.
Misty then waited to see whether Ash was visible as Misty wanted to meet Ash. Misty waited for quite sometime and then realized Ash already reached the stadium and then walked and then climbed the stairs and then reached the hall where the tickets were sold.
"I would like one ticket." Misty said and paid money and the lady on the other side of the counter gave a ticket.
Misty then went and then reached the stairs and then Misty climbed the stairs and then reached a seat which was near the field. Misty then saw Ash who was next to his Kalos companions and Alain who was strategizing. The announcer then said "The match is going to start! Ash and Alain, come to the field for the finals!" Ash and Alain then went to the stairs and then climbed down the stairs and then reached opposite positions in the field.
The first battlefield for the final is a water and rock field. The referee announces the rules of the battle, and asks the Trainers to bring out their Pokémon. Ash chooses his Pikachu, while Alain sends out his Tyranitar, activating its Sand Stream Ability. Clemont sees this as a tactic by Alain to disrupt the vision of Pikachu and prevent it from attacking and moving around, but Serena is not worried, and Bonnie cheers for Ash and Pikachu.
Alain begins the battle by commanding a Dark Pulse from his Tyranitar; Pikachu avoids the attack. Ash sees a strategy and has Pikachu use Iron Tail on the stream of water. The splash from the water clears away the sandstorm while soaking the Armor Pokémon, causing Thunderbolt to deal more damage. Pikachu follows up with Electro Ball, which is countered by a Stone Edge from Tyranitar, and Alain has his Pokémon smash the stones with its tail, sending a barrage of stone pieces at the Mouse Pokémon, only to be reflected back with Iron Tail. Tyranitar follows up with Crunch, but Pikachu uses Iron Tail; Tyranitar, however, grabs his tail in its mouth and swings it back. Pikachu retaliates with Electro Ball, and thus, causes the Armor Pokémon to faint. Ash's friends are excited at an early lead, and Diantha commends Ash on his fighting skills since the semi-finals, something with Professor Sycamore seems to agree with. He then remembers his conversation with Alain and wonders what feelings the latter is holding inside him. Meanwhile, Team Rocket is still intent on their plan to steal the finalists' Pokémon after the battle, while Malva calls them out for the next shot.
Ash recalls Pikachu and sends out his Noivern on the battlefield, while Alain sends out his Weavile. Noivern uses Supersonic but Weavile Protects itself and follows up with Night Slash. Noivern uses Supersonic again, connecting this time around. Alain has Weavile use Ice Beam, but Noivern counters with Boomburst, and follows up with Dragon Claw. Feeling cornered, Weavile uses Double Team to evade the Sound Wave Pokémon, but the latter uses Supersonic to successfully find the real one and proceeds to attack it with Dragon Claw. Weavile avoids the attack and counters with Ice Beam. After some swift dodging, Noivern eventually gets hits by the move, and falls in the stream of water; he is then attacked by Night Slash and is knocked out.
Ash sends out his Hawlucha to battle next, who uses Karate Chop to attack the Sharp Claw Pokémon, but Hawlucha misses every strike. Weavile successfully leads him in the water and uses Ice Beam at his feet, but the Wrestling Pokémon avoids the attack. However, the Ice Beam manages to freeze the stream of water, so that Hawlucha has difficulty walking over it. Weavile uses another Ice Beam, and Hawlucha takes the super-effective hit head-on. Weavile follows up with another Night Slash, but Hawlucha blocks it; Clemont notes that Hawlucha is using the ice to reduce the damage from attacks. Weavile uses Night Slash again, knocking Hawlucha backward, but Ash is unconcerned and claims that Hawlucha gets stronger by taking his opponent's attacks. Alain asks Weavile to use Night Slash again, but Hawlucha responds this time by flying towards the Sharp Claw Pokémon, and throwing it onto the battlefield. Hawlucha then uses Flying Press to successfully knock Weavile out, while inadvertently breaking off the ice as well. Serena, Clemont, and Sawyer talk about the trust between Ash and his Pokémon, and Lysandre takes note of the strength of Ash's Pokémon. Mairin shouts a cheer for Alain, as he sends out his Bisharp to battle, which uses Thunder Wave to paralyze the Wrestling Pokémon. Alain has Bisharp use Guillotine; Hawlucha retaliates with X-Scissor, and the two Pokémon collide head-on. Hawlucha tries to use High Jump Kick but misses, resulting in crash damage, and Bisharp uses Guillotine to knock out Hawlucha. Tierno and Trevor note Alain's strength as Ash and Alain recall their Pokémon; an excited Alain remarks to himself how battling with Ash involves a lot of fun for him and makes him forget about time completely.
Alain sends out his Unfezant next, while Ash calls out his Talonflame. The Proud Pokémon and the Scorching Pokémon have a little exhibition of their flying prowess, before their Trainers command them to use Steel Wing. The two collide, then begin flying against each other again. Ash commands a Flame Charge in order to allow Talonflame to build up speed and move ahead of Unfezant, and Alain responds by having Unfeazant power up with a Sky Attack. The two moves counter each other, after which Alain has Unfezant use Air Slash next. Unfezant allows Talonflame to move ahead of it in order to set it up for an easy attack, and while Talonflame swiftly dodges most of the projectiles it still takes a hit. Talonflame retaliates with another Flame Charge next, successfully hitting the Proud Pokémon. Unfezant uses Sky Attack while Ash has his Talonflame use Brave Bird, and the head-on collision of moves knocks both Pokémon out.
With only three Pokémon left per side, the battlefield goes down for changing. Clemont expresses his concern about the fate of the battle, and Trevor remarks that one little mistake can change the course of the battle. Clemont reveals to Tierno, Trevor, and Shauna that Ash has never managed to defeat Alain, leading Shauna to wonder about the latter's strength, but Serena asserts her own belief, stating that Ash's strength has increased a lot since the last time Ash and Alain battled. On the battlefield, Pikachu cheers on Ash, and the latter encourages Alain to have fun to the end. Alain smiles and remarks to himself about Ash's sportsmanship. Mairin notices Alain smiling, revealing that she had never seen him smile before. Lysandre comments that the finals are about to reach the climax and that every eye will be upon Lumiose City.
The new battlefield is revealed to be a grass-field. Ash sends out his Pikachu to face off against Alain's Metagross. Pikachu begins the battle by using Thunderbolt, but Metagross uses Agility to evade the attack and constantly cut off Pikachu when he tries to get some distance. Metagross strikes Pikachu with Metal Claw, and follows up another hit with Rock Slide. A damaged Pikachu moves the rocks away and is hit by a Meteor Mash. Still hanging on, the Mouse Pokémon counters another Meteor Mash with an Electro Ball and then jumps atop the Iron Leg Pokémon. Metagross tries to shake Pikachu off, but Pikachu's hold is tight, who uses Thunderbolt to deal serious damage. After some effort, and encouragement from its Trainer, Metagross manages to shake Pikachu off itself, but the latter uses Iron Tail on the heavily damaged Metagross, and successfully knocks it out. Mairin seems displeased at the loss, while the group on the sidelines is happy that Ash has taken the lead once again. Diantha and Professor Sycamore praise Ash for his cleverness; James is happy as well that Pikachu has won, something which does not seem to please his teammates.
For his next Pokémon, Alain sends out his Charizard, worrying Ash's friends. Ash has his Pikachu use Quick Attack to hit the Flame Pokémon, followed by a super effective Thunderbolt, bringing Charizard to its knees. Serena wishes luck to Ash and Pikachu, and everyone watches with utter curiosity as the Kalos League finals are reaching their absolute climax.
With the remaining Pokémon being three-to-two in Ash's favor, Pikachu is now facing Alain's ace: Charizard. Pikachu attacks Charizard with a Thunderbolt, but the Flame Pokémon shrugs off the super effective hit as if it was nothing. Ash commands a Quick Attack, but Pikachu's previous battle against Alain's Metagross is starting to show its effect, causing the Electric Mouse to fall on his knee. A Flamethrower from Charizard lands a clean hit on Pikachu, who barely has any strength left to continue. Charizard takes flight and launches another Flamethrower, but Ash, using a tactic learned from Clemont's Bunnelby, has Pikachu use Iron Tail on the ground, creating a cloud of dirt to block the incoming Fire-type attack. Alain compliments Ash's strategy before ordering a Dragon Claw, which Pikachu counters with an Iron Tail. The two moves clash, but the impact is too much for the weakened Pikachu, who finally faints, leaving both sides with two Pokémon remaining.
Back at the stands, Malva is commentating on the events taking place at the stadium, but her cameramen, Team Rocket, are hardly paying any attention to her, instead complaining about Pikachu losing. James, whom Jessie and Meowth had glared at for rooting for their enemy earlier, is glad to see his fellow team members cheering for Ash too, as none of them is wanting to see their longtime enemy lose to a guy like Alain. In the crowd, Ash's friends are discussing the battle situation. Sawyer points out that both of Alain's remaining Pokémon have already battled, while Clemont points that Ash's remaining two Pokémon are still at full health, giving him an advantage. Serena agrees to this, seeing the confident smile on Ash's face. At the VIP box, Mairin is encouraging Alain to do his best.
Ash sends out Goodra as his fifth Pokémon, while Alain chooses to recall Charizard and send out his Bisharp again. In order to create an environment suitable for Goodra, Ash has the Dragon Pokémon use Rain Dance, creating a rainstorm on the battlefield. Goodra begins the offensive with Ice Beam, which Bisharp dodges while charging in for an Iron Head. Goodra blocks the attack by grabbing Bisharp with its horns and then throwing it into the air. Goodra's assault continues with a Dragon Pulse, which is blocked by a Focus Blast from Bisharp. As Bisharp charges in for another Iron Head, Ash has Goodra use Bide, forcing it to take the attack. As Bide is charging, Alain continues his own offensive by having Bisharp attack with another Focus Blast and Iron Head, severely damaging Goodra. Ash launches a counterattack in the form of a full-charged Bide, which hits Bisharp dead on, causing it to fall on its knee. Back at the wetlands, Keanan and the wetland Pokémon are following the battle on TV, while Meyer and Clembot listen to the broadcast from a radio while doing a repair job on a roof in Lumiose City.
Back at the stadium, Bisharp hits Goodra straight into the face with an Iron Head, causing the severely weakened Dragon Pokémon to fall on its knees. Alain orders Bisharp to go for the finish with a Guillotine, which Goodra desperately attempts to counter with a Dragon Pulse, but the Sword Blade Pokémon slices through the counterattack and delivers a devastating Guillotine, causing Goodra's endurance to finally run out and the resilient Dragon-type to faint. In the audience, Ash's friends show concern for him, as he has one Pokémon left and this may as well be his last chance to win the Lumiose Conference. Finally, Ash sends out his last Pokémon of the match: Greninja. As Ash's Water-type is sent out, Malva comments how losing Greninja would result in Ash's defeat. Behind her, Team Rocket grumpily comments on how she's acting as if Greninja's defeat is only a matter of time, as they of all people know how tough Ash can be due to their battles against him all the time.
On the battlefield, both Trainers encourage their Pokémon to do their best. Alain commands an Iron Head from Bisharp, which Greninja counters with a Double Team. As Bisharp is trying to find the real one among the clones, Ash calls a Water Shuriken from Greninja. Bisharp tries to stop Greninja from using Water Shuriken by hitting it while they are both mid-air, but Greninja leaps over Bisharp and makes a direct hit, finally taking Bisharp out of the fight. Sawyer realizes that Ash used the rain created by Goodra's Rain Dance to his advantage, as it powered up Greninja's Water-type moves. For his final Pokémon, Alain calls out his Charizard once again. Both Ash and Alain are determined to do their best with their final battlers. Both Pokémon charge in at each other, and Charizard fires a Flamethrower, but Greninja dodges it and strikes Charizard straight in the chest with Cut, causing the Flame Pokémon to be pushed back just as the rain clouds above the battlefield start clearing up. Even though the rain has ended, Clemont assures everyone that Greninja still has the advantage in type. Serena also has full confidence in Ash.
Looking at Alain, Ash swears he's not going to lose to him, and that he'll fight him with all of his power, activating the Bond Phenomenon and transforming Greninja into Ash-Greninja. Alain, getting excited of seeing Ash bringing out his full power, responds by Mega Evolving his Charizard into Mega Charizard X. With both sides having brought out their best, the entire stadium is ready to witness the final round of the Lumiose Conference to unfold before their eyes.
Ash-Greninja charges at Mega Charizard X and uses Double Team, but Alain has his partner use Flamethrower to get rid of the clones. As all the Double Team clones are wiped out, Greninja emerges from the smoke left behind by the attack and hurls a Water Shuriken at Charizard, which is countered by a Dragon Claw. Ash orders Greninja to use Aerial Ace, and Alain responds with a command for another Dragon Claw. The attacks clash a couple of times until Charizard finds an opening and manages to land a direct hit on Greninja, causing Ash to cringe in pain as well due to the synchronization between him and Ash-Greninja. Charizard fires yet another Flamethrower across the battlefield, but Greninja blocks it just in time by using Cut to slice through the blue-hot flames. Alain has Charizard use its most powerful attack, Blast Burn, but Greninja quickly counters the attack by slamming its Water Shuriken into the ground like a pickax, causing a wave of water to burst out of the ground and block the incoming Fire-type move. Using the resulting steam cloud as a cover, Greninja dashes close to Charizard and strikes it on the head with an Aerial Ace, causing it to get slammed down to the ground.
As Charizard struggles to get back up, Alain congratulates Ash on giving him a thoroughly enjoyable battle. But, as Mairin's image flashes in his mind, he then loudly declares that he's going to be the strongest, and will not lose to anyone anymore. A Dragon Claw from Charizard follows, slamming Greninja across the battlefield and causing Ash to cringe again. As Greninja gets back to its feet, Ash admits he's also been enjoying battling a strong opponent like Alain, but also vows that the battle is going to end now. After promising that there'll be no hard feelings no matter who wins, Ash commands a Cut from Greninja, getting a response from Alain in the form of a Dragon Claw. Both powered-up Pokémon clash furiously in the middle of the field for a few times, after which simultaneous attack commands are given by both Trainers: Water Shuriken from Greninja, and Thunder Punch from Charizard. Again, fierce attacks clash in the middle of the field for a few moments, until the Water Shuriken finally overpowers the Thunder Punch, and Greninja slams the shuriken straight into Charizard's chest, causing the Fire-type to slide back. Preparing for his ultimate move, Ash has Greninja use Water Shuriken, but this time, Ash-Greninja's watery aura wraps itself around the Water Shuriken, causing its size to increase dramatically and turning its color from watery blue to blazing orange. Alain, momentarily taken aback by the sight, orders Charizard to use Blast Burn. Both moves are fired at the same time, and both Greninja and Charizard can only watch as their opponent's ultimate attack strikes them, creating a massive explosion on both sides of the field.
The entire crowd is looking at the field in anticipation, no one making a sound. As the smoke and steam clouds clear up, both Pokémon are still standing. For a few moments, both Greninja and Charizard look at each other, not moving at all. Greninja was about to faint and Misty wanted to see Greninja win as that was Ash's chance to win a League and she did not want the legendary transformation to lose.
"Greninja! You can do it! Just one more Water Shuriken!" Misty shouted and the whole stadium looked at Misty and Ash noticed Misty who shouted the command and Ash said "Water Shuriken!". Greninja made a final Water Shuriken and then threw the Shuriken at Charizard who then fainted.
"It is good that Ash won but for another trainer to command Greninja would be cheating?" Bonnie asked.
"I do not know." Serena said.
"It is probably considered a cheer." Clemont said.
"I won. But that was Misty who showed me the idea. My victory is due to Misty who helped me." Ash said quietly.
"Lysandre would be angry at me for losing! I am now going to confront Misty!" Alain said and then ran from the field. Alain then climbed the stairs and then went to Misty and shouted "Because of you, I lost the match! The match was betwwen me and Ash and you were not supposed to advice Ash!"
"Yes, but I do not want to see the legendary transformation to lose." Misty shouted.
Ash then ran and left the field and climbed the stairs and then went to Alain and then said "I was the one who commanded Greninja after that. What has happened has already happened." and Alain then left Ash and Misty who looked at Alain who ran from the area.
Ash and Misty then went to the stairs and then climbed down the stairs. Ash then went to the podium and then took the trophy and Misty smiled at Ash as he won his first major League trophy. Ash then said "I dedicate this victory to Misty."
"You are so sweet! But you also are responsible." Misty smiled and said.
Serena, Clemont, and Bonnie then climbed down the stairs and then saw Ash and Misty. Serena was curious as to why was Ash close with another girl and then Ash said "This is Misty with whom I used to travel with." and Serena said "Hi." and Clemont said "Hi, Misty! Nice to meet you." and Bonnie said "Hi, It was nice meetng you!"
"It is nice to meet you all!" Misty smiled and said.
