The battle between Cameron and Ash officially begins. Cameron calls out his secret weapon: a Hydreigon! The sight of the legendary Pokémon surprises Ash and delights the audience, especially Iris. Ash calls out Boldore, which Cilan says is a good choice. Cameron starts the battle with Tri Attack. Boldore attempts to dodge, but is still hit. Hydriegon fires a Dragon Pulse which also scores a direct hit, doing a lot of damage. Stephan looks in amazement at Hydriegon's power. Boldore struggles to his feet and attacks with Rock Blast, which Hydriegon dodges. Boldore follows up with Rock Smash which manages to score a direct hit. Hydriegon counterattacks with Dragon Rush, which hits Boldore hard. Hydriegon then makes another hit with Tri-Attack. Ash calls for Flash Cannon, which Cameron counters with Dragon Pulse. The dragon-type move overpowers Flash Cannon and hits Boldore, knocking it out.
Ash recalls Boldore and thanks it for its work. He tells Cameron he's impressed with his Hydriegon before calling out Oshawott, to Bianca's confusion. Stephan thinks Ash wants to use Oshawott to take away some of Hydriegon's stamina but Cilan and Iris know Ash will do his utmost best to defeat Hydriegon. Ash proves their point by calling an Aqua Jet, which scores a direct hit. Oshawott follows up with Razor Shell, which Hydriegon dodges. Hydriegon then hits with Dragon Pulse, but Oshawott recovers quickly. Oshawott uses Razor Shell again which after a few misses, scores a hit. Cameron compliments Oshawotts power as Riolu looks in surprise. Oshawott attacks with Hydro Pump and scores another direct hit. Hydriegon attacks with Tri Attack and hits Oshawott. Oshawott gets up and, angered, blasts forward with Tackle, which slams into Hydriegon and does a considerable amount of damage. Oshawott attempts to follow up with Razor Shell, but Hydriegon counters with Double Hit which hits Oshawott before he can attack. Hydriegon follows up with Dragon Rush which hits hard and knocks Oshawott out leaving Ash down two Pokémon.
Virgil and Eevee nervously consider the fact that they could be facing Hydriegon if Ash loses. Ash recalls Oshawott and calls out Pignite. Pignite starts with Brick Break which scores a direct hit. Hydriegon thens hits Pignite with Dragon Pulse, but Pignite recovers quickly and uses Flamethrower, which grazes Hydriegon. Hydriegon attacks with Tri Attack which Pignite unsuccessfully dodges. Pignite then takes a hard hit from Dragon Rush. Pignite manages to get up and uses Brick Break, scoring a hit. Ash calls a Flame Charge, which scores another hit, doing a lot of damage to Hydriegon. Hydriegon attempts to hit with Double Hit but Pignite dodges and, with Hydriegon on the ground, uses Fire Pledge. Hydriegon flies above the Fire Pledge and dodges it, but the distraction allows Pignite to score a powerful hit with Flamethrower. Ash tells Pignite to finish it with Brick Break, which Cameron tries to counter with Double Hit. However, Pignite dodges the Double Hit and lands his move on Hydriegon, finally knocking it out.
Cameron recalls Hydriegon and briefly thinks about which Pokémon he wants next. He then calls out Ferrothorn. Ferrothorn uses Metal Claw, which Pignite easily dodges. Ferrothorn then uses Pin Missile, which manages to hit. Pignite then lands a super-effective hit with Flamethrower. Ferrothorn uses Mirror Shot, but Pignite dodges and uses Flame Charge, which hits and knocks out Ferrothorn.
Cameron then calls out Samurott, getting the type advantage over Pignite. Pignite uses Flamethrower, which is easily overpowered by Hydro Cannon. Pignite then tries Brick Break, which Samurott dodges. Samurott thens uses Aqua Jet and hits Pignite, knocking it out.
Ash recalls Pignite and orders Pikachu to the field. Cameron is excited to battle Pikachu. Pikachu uses Thunderbolt, but Samurott surprises everyone by blocking it with Razor Shell. Pikachu then uses Quick Attack, which, again, Samurott blocks with Razor Shell. Samurott then hits with a powerful Hydro Cannon. Samurott then charges forward with Megahorn, which Pikachu manages to dodge. Pikachu uses Quick Attack again. Samurott attempts to block with Razor Shell, but this time Pikachu dodges and hits Samurott right in the face. Pikachu then follows up with an Iron Tail, which also hits and does serious damage to Samurott. Pikachu uses Electro Ball, which Samurott manages to block with Razor Shell. The distraction, however, allows Pikachu to land another Iron Tail, which knocks out Samurott.
Cameron recalls Samurott and calls out a Swanna, surprising Iris, as it has a major disadvantage as it is a Flying/Water type. Cilan points out that it has an aerial advantage over Pikachu. Swanna flies up high and attacks with Pluck, which Pikachu easily dodges. Pikachu uses Quick Attack, which Swanna dodges. Swanna uses Wing Attack and successfully hits Pikachu doing some damage. Swanna uses Bubblebeam, which Pikachu dodges. Swanna then uses Wing Attack again, which Pikachu dodges. Pikachu then hits Swanna with an Electro Ball and knocks it out.
Cameron recalls Swanna and calls Riolu to the field telling him hes his last chance. A confused Ash asks him if he has another Pokémon beside Riolu left, to which a horrified Cameron responds that he thought a Full Battle was 5 on 5, not 6 on 6. This means Riolu is Cameron's last Pokémon, while Ash still has three.
Ash recalls tells Pikachu to take a break and replaces him with Unfezant. Unfezant uses Gust and Quick Attack, both of which Riolu easily dodges. Riolu lands on Unfezant's back and hits with a powerful Force Palm. Unfezant shakes off Riolu and uses Air Cutter, which Riolu dodges. Riolu then uses Copycat and hit Unfezant with Air Cutter. Riolu then connects with a Vacuum Wave. Unfezant tries to hit with Aerial Ace, but Riolu ducks and uses Circle Throw, sending Unfezant into the wall and knocking her out.
Ash recalls Unfezant and calls out Snivy. Riolu attacks with Vacuum Wave, which Snivy easily dodges. Snivy counterattacks with Leaf Blade and hits Riolu right on the head. Riolu uses Copycat and hits Snivy with Leaf Blade as well. Riolu uses Vacuum Wave again, which Snivy dodges again. Riolu then grabs an airborne Snivy and uses Force Palm on her. Riolu then uses Circle Throw and sends Snivy into the wall. Snivy gets to her feet and is furious. Snivy attacks with Leaf Storm, which Riolu dodges. However, the distraction allows Snivy to grab Riolu with Vine Whip and begins slamming it into the field, doing a notable amount of damage. Riolu uses Vacuum Wave to both escape and hit Snivy. Riolu uses another Vacuum Wave, which this time Snivy dodges with Vine Whip. Snivy then launches a devastating Leaf Storm, sending Riolu flying and doing major damage.
Riolu appears to be finished, but then begins to glow. A surprised audience realizes what's happening. Riolu has started to evolve! Riolu becomes Lucario and lets out a battle cry, while Snivy and Ash stare in utter shock at the sight.
