The bipedal Fighting- and Steel-type Pokémon that evolves from Riolu. Lucario uses his Aura abilities for short- and long-ranged attacks, as well as for reading his opponent’s movements and judging their character.
Lucario returns to Smash Bros. even stronger than before, with his signature Aura mechanic of becoming more powerful the more damage he receives has been powered up, affecting more moves and delivering more damage. It all maxes out when he uses his Final Smash to Mega Evolve into Mega Lucario, in which his maximal Aura levels increase his attack power and speed to their utmost limit.
