The battle between Cameron and Ash officially begins. Cameron calls out his secret weapon: a Hydreigon! The sight of the legendary pokemon 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 thier 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, causing it to recoil in pain. 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 pokemon.
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.
