Bellossom • Bewear • Blastoise • Bonsly • Celebi • Chansey • Charizard • Chespin • Chikorita • Clefairy Riley has a Lucario, which is his only known Pokémon. He trained it while he was on Iron Island in Serious Training on Iron Island!!. A most gallant-looking creature. It emits energy waves and controls them with precision, using them to sense even faraway beings. I have given the name “aura” to this power. Lucario is the only Generation IV Pokémon to be playable in the Super Smash Bros. series, though many others appear from Poké Balls.In Z-Move Showdown!, Professor Kukui used a Lucario to battle a Shiny Guzzlord that interrupted the closing ceremony of the Manalo Conference, only for it to be defeated and recalled to its Poké Ball. In A Full Battle Bounty! and Fiery Surprises!, Lucario was Kukui's fifth Pokémon during his Full Battle against Ash. It went up against Ash's Naganadel and lost. Lucario may be derived from the reverse of the Japanese transcription of orichalcum (a mythical metal) or oracle (referring to its supernatural abilities involving aura).
