Aura
Lucario's attacks have the aura effect. By itself, aura has no effect other than producing blue flames; when used by Lucario, however, the damage of the attack is altered based on Lucario's current damage and placing in the match.
In Brawl
In Brawl, only Lucario's dash attack, back throw, down throw, and floor attacks are unaffected by aura. The formula of the value used to strength or weaken aura attacks is as follows:
...where r is the ratio of the damage dealt (for example, if r is 80, the attack is at 80% strength) and d is Lucario's current damage.
It is a common misconception that aura attacks reach maximum power at 182%, not the actual 170%. This is due to Event 25: The Aura Is With Me placing Lucario at 182% to start the match, implying that 182% is the maximum.
In SSB4
In SSB4, the effect of aura has been increased overall - the limits are more extreme, as are the multipliers at those extremes. In addition, all of Lucario's attacks are now affected.
Notes
- A less common misconception is that each of Lucario's attacks has an individual aura cap. This is due to the game not displaying or otherwise acknowledging the presence of decimal figures, so an attack dealing a maximum of 9.8 damage can be believed to be the same as one with a maximum of 9.0 at a lower percentage.
- When copying Lucario, Kirby does not copy the aura mechanic; his Aura Sphere will remain at base power regardless of his damage.
