Poketto monsutâ - Season 17 Episode 33

On their way to Must Mountain for Corni's special training, our heroes enter a winding cave where they encounter a swarm of agitated Onbat–stirred up by the Rocket-Dan trio in one of their schemes. In the confusion, the friends get separated: Satoshi, Serena, Eureka, and Lucario end up at one entrance to the cave, while Citron, Corni, and Pikachu are at the other. The villains take advantage of the opportunity to strike against Citron's group, and thanks to the "Mecha Evolution" devices attached to the Rocket-Dan Pokémon, they quickly get the upper hand. Meanwhile, Lucario has sensed Corni's presence, and thanks to their bond and the scouting skills of Satoshi's Yayakoma, the two groups are reunited–but even Lucario can't overcome the Rocket-Dan's technology. As a last resort, it Mega Evolves again–and promptly loses control as the power of its aura drowns out Corni's voice. But Corni is persistent, and Mega Lucario comes to its senses just long enough to send the Rocket-Dan blasting off again before it collapses, exhausted. Their journey is just beginning.
