Ash then calls upon Pikachu, who hasn’t fully recovered from its earlier battles. Pikachu’s power and tenacity are amazing as always, the result of the strong bond between Trainer and Pokémon, and it battles Lucario almost to a standstill. But Lucario manages one final Aura Sphere to seal Pikachu’s defeat. Ash is out of the Unova League, and Cameron moves on to the semi-finals...
...where he’s up against Virgil and Team Eevee, and Flareon’s type advantage finally overcomes the powerful Lucario! Virgil’s Eevee proves to be a fierce competitor as well, knocking out his final opponent’s Druddigon to win the Unova League!
After our heroes bid a fond farewell to their friends and rivals, we leave Ash contemplating all the wonderful adventures yet to come—and feeling more determined than ever to make his dream of becoming a Pokémon Master come true!
Ash and Cameron's Full Battle resumes, with Ash left with his Snivy and Pikachu. Although Cameron only has his newly-evolved Lucario, things are just getting started. Ash has Snivy score a quick hit with a Leaf Blade. Recovering quickly, Lucario counters with a Force Palm that throws Snivy across the field. Bianca remarks that Lucario's Force Palm is much stronger than it was when it was just a Riolu, to which Stephan states it is because Lucario had just evolved. Ash then has Snivy use Vine Whip, but Lucario blocks the attack. Not willing to give up, Ash has Snivy keep attacking Lucario with a barrage of Vine Whips, but Lucario keeps blocking them. Seeing an opening, Cameron has Lucario grab onto Snivy's vines and use Circle Throw, slamming Snivy into the ground. As the dust clears, Snivy appears to have been knocked out. With some encouragement from Ash, she manages to get up and continue the battle. Wanting to end the battle quickly, Cameron has Lucario demonstrate his new move Aura Sphere. Snivy attempts to dodge, but the attack follows her and lands a direct hit. The attack generates an explosion that throws Snivy to the ground causing her to faint. Eliminated from the battle, Ash is left with just Pikachu.
Cilan comments that although both Trainers are left with one Pokémon each, Pikachu hasn't yet recovered from his earlier battles with Cameron's Swanna and Samurott. Starting the battle, Pikachu strikes first with Quick Attack. Wanting to wrap the battle up as fast as possible, Ash has Pikachu use two additional Quick Attacks. Lucario looks like it is almost beaten so Ash orders Pikachu to go in close with Iron Tail, but Lucario manages to slide away. Jumping up, Lucario comes in from above with Force Palm, throwing Pikachu across the field. Cameron has Lucario follow up with Aura Sphere. At the same time, Pikachu lets off an Electro Ball. The attacks collide in midair and explode, throwing both Trainer's Pokémon away. Both Pokémon are able to get up, but Pikachu looks like he is struggling more.
Pausing the battle, Cameron talks with Ash, saying he feels great competing in the Vertress Conference. Ash says he feels likewise and they continue the battle. Both Pokémon run toward each other. Lucario attempts to land a Force Palm, but Pikachu jumps over Lucario and dodges the attack. Not wanting to give up, Lucario follows and grabs Pikachu, tossing him high into the air with Circle Throw. Almost cat-like, Pikachu somersaults in the air and lands lightly on his feet. Following up, Pikachu hits Lucario with a powerful Thunderbolt and goes in close to hit with a Quick Attack. Pikachu is visibly exhausted but comes back around with an Iron Tail. Cameron and Lucario are determined not to give in though and Lucario uses Copycat which turns into Iron Tail as well. The two attacks collide which causes an explosion. Falling from the cloud, the two Pokémon hit the ground hard. Both Trainers encourage their Pokémon to be the first to get up, and they soon do so. Ash tells Pikachu to use Electro Ball with everything he has while Cameron orders Lucario to charge up an Aura Sphere. The two attacks collide, but Lucario's Aura Sphere manages to push away Pikachu's Electro Ball and it hits Pikachu, ending the battle. The referee makes the call, awarding Cameron the victory as he moves on to the Top 4. Both Trainers congratulate each other and their Pokémon.
The next day, Cameron and Virgil are battling in the semi-finals. Cameron is left once again with only Lucario while Virgil still has three Pokémon left. Recalling his Espeon, Virgil calls out his Flareon. Cameron, not worried about typing, has Lucario go in with a Force Palm, but Flareon uses Double Team to evade the attack before using a super-effective Flamethrower, but Lucario is still able to battle. Hoping to get an idea, Cameron tries snapping his headband, but nothing comes to mind, so he just has Lucario attack with Aura Sphere. Flareon counters with Fire Blast, punching through Aura Sphere and striking Lucario out for the count. With his last Pokémon down, Cameron loses the semi-final.
Later, Virgil and Team Eevee take on Dino in the Vertress Conference finals. Both sides are down to their last Pokémon, Virgil’s Eevee versus Dino’s Druddigon. Druddigon uses Dragon Rage, but Eevee evades the attack with Dig. Coming out of the ground, Eevee hits Druddigon with Iron Tail, throwing Druddigon to the ground. Finally, Eevee knocks out Druddigon with Trump Card, making Virgil the winner of the Vertress Conference. Meeting up by a fountain, Ash, his friends and many Unova rivals congratulate each other on their efforts. Virgil’s older brother Davy soon arrives to pick Virgil up, the group says farewell to him as he flies away. Just then, Bianca runs up trying to catch Virgil, but is late and knocks Ash into the fountain. She instead gives everyone the Casteliacones to enjoy. Cameron and Lucario devour theirs and run off to train. Bianca decides to head back home and leaves immediately.
Ash and Stephan return to the sauna to discuss their plans for the future. While Ash has no plans of returning to Pallet Town, both Trainers vow to get stronger for a rematch. At the hotel, Cilan and Iris are packing but Ash has slipped away to go back to the stadium to reflect on his performance and what it took him to get here. After the flashback ends, Ash declares that his journey is not over yet. Soon Cilan and Iris find him staring at the sunset, and call him over so they can get going.
