Lucario

"Watch the power of Aura!"

- Lucario

Lucario is a Fighting/Steel-type Pokémon from the Pokémon series. While most Pokémon in the Super Smash Bros. series are indeterminately gendered, this one is confirmed to be male, as shown via Solid Snake's codec, and from the description of one Event Match (The Aura Is With Me). Lucario originates from the fourth Generation Pokémon games: Pokémon Diamond, Pokémon Pearl, and Pokémon Platinum Versions, is the evolved form of Riolu, and as of Generation VI can Mega Evolve into Mega Lucario.

Super Smash Bros. Brawl
Lucario appears as an unlockable playable character in Super Smash Bros. Brawl. He can be unlocked by playing 100 Brawl matches, completing every level of Target Smash with one character, or by having him join the party in The Subspace Emissary by clearing The Glacial Peak. His voice clips in this game are provided by Bill Rogers in the English release, who voices Lucario for the television series, and Daisuke Namikawa in Japanese, who provided the voice of the Lucario in the movie Pokémon: Lucario and the Mystery of Mew and the Pokémon Diamond and Pearl seasons of the animated series.

Lucario's attacks and abilities mostly revolve around aura, which increases in power the more damage Lucario takes (though this only applies to attacks that use its aura). His neutral special move is Aura Sphere, in which Lucario charges and throws a ball of aura energy. His side special move is Force Palm, in which Lucario thrusts its hand forward to attack with a burst of energy. His down special move is Double Team, in which Lucario counterattacks an opponent that attacks it. His up special move is ExtremeSpeed, in which Lucario flies in the direction the player inputs. His Final Smash is Aura Storm, in which Lucario leaps into the air and fires a beam down onto the stage.

The Subspace Emissary
Lucario is first encountered in The Subspace Emissary at the top of The Glacial Peak, where it is balanced on the peak when Meta Knight and the Ice Climbers arrive. Lucario and Meta Knight battle (the player able to control either character), and the loser is turned into a trophy. The winner revives the loser, and the two shake hands, now allies. However, in its battle with the Great Fox, the Halberd smashes the Great Fox into the mountain, allowing Lucario and Meta Knight to climb aboard the Halberd.

As the two are traveling through the Halberd, Lucario senses Solid Snake's aura from inside his Cardboard Box and exposes him. His cover blown, Snake and Meta Knight are about to fight, but Lucario stops them, sensing the aura of some nearby Primids which they fight instead. As the three travel on they find a room where the Trohpies of Peach and Zelda are being held in cages. Shadow Bugs then appear and take the form of the princesses, which Lucario, Meta Knight and Snake battle. After the clones are defeated the actual Peach and Zelda are freed and left in the room while the group travels on. They arrive at the bridge, where they find multiple Mr. Game & Watches controlling the ship. Snake knocks them all onto the main deck, where they dissolve into Shadow Bugs and reform into Duon. Snake and Lucario leap down onto the deck, teaming up with Sheik, Peach, Fox, and Falco to fight. After it is defeated, Duon dissolves to reveal the actual Mr. Game & Watch's trophy, which Peach restores.

The Halberd lands in the desert, where most of the cast units. They all then fight against the Subspace Gunship and make it to Subspace. Inside, the team stand against Tabuu, but are all instantly turned into Trophies. However, they are all eventually restored and head to face Tabuu. After he is defeated, everyone returns to the real world, the Subspace portals all closed.

Snake's codec

 * Mei Ling: You're fighting Lucario, aren't you, Snake?
 * Snake: Mei Ling, what's that purple fire coming out of his hands?
 * Mei Ling: That's his "Aura."
 * Snake: Aura?
 * Mei Ling: I guess you could call it his life force. Lucario can use his own Aura and turn it into power. Every time Lucario's damage increases, his Aura gains strength, making his attacks more powerful. So don't think you've got him beat just because his health is down.
 * Snake: The cornered rat will bite the cat... Sounds like trouble.
 * Mei Ling: Hey! When did you become so good with proverbs?!
 * Snake: You must have rubbed off on me.
 * Mei Ling: Well, come back in one piece, and I'll teach you all the Chinese proverbs you can handle.

Trophies
Blue indicates the Trophy or description is exclusive to the Wii U version.

Palutena's Guidance

 * Viridi: What the heck is that?!
 * Pit: Oh, that's Lucario. What about it?
 * Viridi: I've never seen a creature with a life force like that! It's like a current of water. Or a whirlpool!
 * Palutena: Oh, you mean Lucario's Aura.
 * Viridi: Aura?
 * Palutena: Lucario can sense the life force—or Aura—emanating from all living things. As Lucario takes more damage, its own Aura grows stronger.
 * Viridi: Ingenious! Lucario sounds like a perfect fit for the Forces of Nature.
 * Pit: We need to focus on the fight at hand.
 * Viridi: You focus on the fight at hand. I gotta catch my new recruit.
 * Pit: No! Stop!
 * Palutena: Pit, a wounded Lucario is stronger than it looks. Be extra careful when it's taken lots of damage.

amiibo

Lucario is the only known Fighting- and Steel-type Pokémon and evolves from Riolu during the day when its happiness is high enough.
