Eurytheus told Ash to capture a Hydreigon near Opelucid City. Ash gotten the Pokemon he's gonna use, and give the water pokemon to his battle judge, Inigo. He took a plane over to the Unova Region and walked to Opalucid City. There at the Pokemon Center, Ash ran into someone he hadn't seen in years. "Iris is that you?" he asked. The girl Ash once knew at Nurse Joy's desk turned around and was surprised. "Why, it's Ash!" she said. "I knew it long time, no see." When Ash last saw Iris, she has become the Opelucid gym leader. "So how's the Gym leader life." He asked. "Busy." Iris answered. "But ever since that Hydreigon came to town, things have been rough." "You know Iris," Ash said, "I came here to catch that Hydreigon. Iris was surprised. "Why?" she asked. "I'm trying to complete these tasks, so I can save my family and pokemon." He said. "What happened?" she asked. He told Iris the whole story.
"Wow," Iris said. "That's horrible." "It is." Said Ash. "That's why I have to Catch Hydreigon." "Well you won't be going alone." Iris said standing up. Iris told Ash that she wants to come with Ash. Because as a Dragon Master, it's her job to make sure all Dragon-Types are fine. Ash and Iris went out of the Pokemon Center to find the Hydreigon. But Iris reminded Ash that they need to know where the Hydreigon was. "What a little kid." She said. "Iris," Ash said. "I'm thirty years old; you think you can stop with this kid nonsense?" "Afraid not." Iris said.
That night, they were in a field. The night was cold, the field was dark, the wind was howling, then out of the clouds, came a three-headed, draconic Pokémon with six thin, black wings. "Dreigon!" It was the Hydreigon Ash has come for. Ash and Iris unleashed Charizard and Dragonite, an old team from the Decolore Islands. "Let's do this Iris!" Ash said. "Pikachu." "Just like old times!" Iris said. "Charizard, use Slash!" Charizard's claws glow white and grow longer. It slashes the Hydreigon with them. Hydreigon was about to unleash a powerful Dragon Breath, when… "Dragonite, use Thunder Punch!" Dragonite then punches the Hydreigon with a fist of yellow sparks. Hydreigon grabbed the Thunder Punch with its hands and throw him to the ground. Hydreigon unleashed a powerful Tri Attack. "Charizard, use Wing Attack to protect Dragonite!" Charizard flew in front of Dragonite to protect him.
All night they battled the Brutal Pokemon, but no matter what they can't land a single move on it. "Charizard, use Dragon Tail!" When Charizard tries to land its glowing tail on its opponent, Ash knows what was going wrong. "Iris, let's attack together." Ash said to Iris. "Why?" she asked. "We've been battling Hydreigon indivisibly," he said. "but if we attack Hydreigon at the same time at different points we can bet it." Iris agreed. They both commanded their dragon pokemon to use Slash and Thunder Punch. Hydreigon tried to dodge one of their attacks, but the two pokemon hit Hydreigon. Hydreigon has gotten injured in the last attack. Now they used Dragon Tail and Dragon Rush, and once again Hydreigon was hit. With two dragon type moves hitting a dark and dragon type, Hydreigon took some major damage. Now Ash and Iris commanded Dragonite and Charizard to use one more attack. "Use Flamethrower!" They both released streams of fire at the blue and black dragon pokemon, making it unable to battle. As it fell to the ground, Ash threw his pokeball at it. The ball shook and shook, has Ash caught the Hydreigon, or is this challenge a failure. Then when the pokeball shook the seventh time, Hydreigon was officially caught. "All right, I caught a Hydreigon!" he said. "Pi pikachu!"
Just then a blue bird like pokemon shows up with a message. "Altaria." Iris took the message and looks at it. "What's it say Iris?" Ash asked. "Pikachu?" "I have important business at the gym." Iris answered Ash. "Good luck Ash, I hope you save your family." "Thanks Iris." Ash said in return. "Good luck with the gym leader business." "Pika!" Ash returned to the Pokemon Center and called Mycenae Incorporation. Eurytheus was not happy when he heard the news.
