Lucario did not accept the fact that Maylene gave up after her loss to Paul, as seen in Lost Leader Strategy!, when it fired multiple Aura Spheres and Bone Rushes at her during their training, thought this maybe the result of some where deep down believing that she had what it took to still be a great gym leader. While stern, it cares deeply for her and will not tolerate people talking negatively about Maylene, especially shown when it sends Team Rocket flying for saying how pathetic she was.
Lucario appeared in the Rising Rivals expansion. Its card featured the Platinum version of the Veilstone City Gym, and its Level matched the level it had in Pokémon Platinum, as well.
