Super Smash Bros. for Nintendo 3DS/Lucario

The Aura Pokémon makes a comeback in Super Smash Bros. for Nintendo 3DS and Wii U! At first glance, Lucario is an awful character, with moves dealing miniscule damage, sluggish KO moves and average range. Thankfully, Lucario retains its signature Aura mechanic, with some significant buffs, which makes it stronger the more damage it takes. Powered up by Aura, Lucario becomes a threatening beast, with huge Aura Spheres, long range Force Palms and absurd power on its attacks. Lucario is built as a high risk, high reward character, with a heavy emphasis on surviving at high damage. If you can stay alive within an inch of your life as Lucario, you can turn around any losing situation, or make the smallest point lead insurmountable.

Basic Attributes
Lucario is a middle weight, and his stats, none of which are affected by Aura, are pretty standard as well. Lucario has slightly below average movement speed, running about as fast as Ike. His dodges are decently fast and have average range. Lucario's jump is pretty good, and he has moderate lateral air speed and intermediate fall speed. Lucario can both wall jump and wall cling, and he has among the longest wall cling duration among the fighters with this ability. This feature helps Lucario a lot in stages with long walls down the sides, as it aids in Lucario's recovery.

Aura
Lucario has a unique mechanic called Aura. All of Lucario's moves are affected by Aura. When Lucario takes damage, its Aura will be powered up, capping at 190%. The higher Lucario's Aura is, the stronger its attacks will be, in terms of both damage and knockback. The increased knockback also stacks with the Rage mechanic that applies universally to all characters, making Lucario ridiculously powerful at a high percentage. Additionally, Lucario's special moves have altered properties other than damage and knockback based on Aura. Aura Sphere becomes larger, Extreme Speed moves further, and Force Palm gains increased range.

Final Smash - Mega Lucario
With the mystical power of Lucarionite, Lucario undergoes a Mego Evolution to become Mega Lucario! Lucario's attacks will be boosted by full-power Aura no matter what its damage currently is. Lucario also gains super armor for the duration of its transformation, but getting attacked will cause it to change back faster. This transformation Final Smash might feel a bit underwhelming compared to others in the same category, as Lucario's attacks don't seem to have drastic changes at first glance. If so, you might be underestimating the insane power of Lucario's Aura. Since Lucario's Aura caps at 190%, you will rarely have a chance to utilize it to its full potential, so all of your attacks will be surprisingly potent. The Final Smash's super armor helps you go on a full offensive, as your foes have no way to interrupt your absurdly strong moves.
