Our heroes and Shalour Gym Leader Korrina have arrived in Geosenge Town to look for a Lucarionite, the Mega Stone needed for Lucario’s Mega Evolution. A photographer points them to a mountain cave but warns them it might be dangerous. Sure enough, when they get to the cave, the Team Rocket trio come flying out, propelled by some unseen force! But Korrina is determined to keep going.
Inside the cave, they find the Lucarionite—but it’s guarded by a powerful Blaziken, who challenges Korrina and Lucario to a battle! It’s a bad matchup for Lucario, and Blaziken’s speed is intimidating. Korrina refuses to give up, and Lucario has almost won when someone calls the battle to a halt! It’s Korrina’s grandfather, the Mega Evolution guru known as Gurkinn. Now that Korrina has proven herself worthy, Gurkinn invites her to claim the Mega Stone she’s been looking for. Lucario’s Mega Evolution is close at hand!
