Lucario (USBIV)

Lucario is a startable playable character in Ultra Smash Bros. IV and makes his third return in the series since Brawl. He was confirmed alongside with Sceptile's trailer and he's also been seen there. In the Pokémon series, Lucario is a Generation 4 Pokémon, as a Fight-Steel type, that pocesses the Aura powers. He's the final evolution of Riolu.
Lucario's voiceclips were reused from Smash 4.
Lucario ranks the 44th place of the 103rd in the tier list, putting him at the high tier (B+), before Ganondorf and after Jigglypuff, as a high tier character. This is a slightly drop for Lucario but maintains his spot as a high tier character as in Smash 4.
Lucario pocesses a strong comboing game and a strong defensive gameplay with his Aura Ball. Double Team stays the strongest counter of the game (even with Corrin, second is Roy paired with Shulk). Extreme Speed goes unexcpetedly faster and has a invisibility/intangible frame.
Force Palm has been nerfed for his grab range and lag. Also his rage, who's the rage in the game (even with Pichu) is 3% reduced based on knockback. Overall in his matchups, he does really good against higher tiers thanks to his powerful aura and rage.
