Cameron had his Riolu evolve into Lucario and easily pulverized Ash's Snivy and Pikachu winning Cameron the match, despite bringing only five Pokémon into battle (His Riolu turned Lucario being the last member of his team, after Hydreigon, Samurott, Ferrothorn, and Swanna). Cameron did use his Lucario against Virgil only for it to lose to Virgil's Flareon, because of Lucario's weakness to Fire-types and Cameron's poor strategy. In the XY series, Ash meets Korrina, the Fighting-type Gym Leader, who owns a Lucario capable of Mega-Evolution.

As a result, Korrina and Lucario have to train under Mabel and her Mega-Mawile in order to learn to be in sync with each other through floral designs. Korrina was later successful in calming Lucario's rage; she used it in battle against Ash for the third Kalos Gym badge but lost. In the Journeys series, Korrina used her Mega-Lucario against Ash in the Battle Festival only to again lose to him and his newly obtained Dragonite. In Sun and Moon series, Professor Kukui/Masked Royal was revealed to own a Lucario to help drive back the three Guzzlord that were attacking Alola, shortly after Ash was crowned Champion of Alola.

In Pokémon Journeys, Ash was able to obtain a Lucario himself when his Riolu evolved to fight against and defeat Chairman Rose's Ferrothorn and Copperajah. Ash later gets his Keystone from Korrina and heads to Mega Island to obtain a Lucarionite. He was able to succeed in Mega-evolving his Lucario and used it to knock out Bea's Gigantamax Machamp.
