Aura Storm

Aura Storm is Lucario's Final Smash move in Super Smash Bros. Brawl. Once the Smash Ball is broken open, Lucario will begin to glow and rise into the air. He will then fire a powerful ray blast of Aura on a portion of the stage. It will continue to devastate any player who happens to even come close to the beam, dealing heavy damage on those caught in it. The ray can be aimed using the control stick, allowing Lucario to catch his opponents easier. The attack lasts for about 5 seconds, before finally ending, sending a minor explosion that launches players into the air.

''Lucario's Final Smash. After flying off the screen, Lucario reappears in its center. He then launches a powerful Aura attack against all foes within a certain distance. The key to this attack is the ability to change its angle--it's a must to sweep slowly left and right to hit selected enemies multiple times. The last blow will send the victim flying away.''
