In episode XY032, Korinna uses her Mega Lucario to battle Ash, but due to lack of control over its transformation, it soon runs out of control until Gurkinn's Lucario stops it. In XY034, Lucario finally gains full control of its Mega Evolution and successfully defeats Team Rocket, who were attacking Ash and his friends. It later participated in a gym battle against Ash in XY44, using it's newfound Mega Evolution to defeat Ash's Fletchinder and Hawlucha, though eventually losing to his Pikachu. This Lucario appeared again in the 25th episode of Pokemon Journeys, facing Ash's Gengar and Dragonite, defeating the former but losing to the latter.
