Aura Storm

Aura Storm is 's Final Smash in Super Smash Flash 2.

Overview
When performed, Lucario shouts "Max Aura!" and uses Extreme Speed to fly upwards toward the top of the screen, where it launches a beam of aura energy downwards. The beam can be angled left or right up to a certain amount, and opponents caught in it will rapidly take hits dealing 2% damage each. After a certain period of time, the beam is dispersed, ending the move and dealing 14% damage with strong knockback to opponents hit. The move can deal up to 90% damage in total to opponents hit and is capable of being a one-hit KO move.

Origin
While Aura Storm is not an actual move in the  series, the move seems to be based off of a powerful special Normal-type attack, known as Hyper Beam, which forces the user to waste a turn recharging after a successful use. Hyper Beam is mainly learnt by fully evolved Pokémon, like Lucario. It is also very similar to the Kamehameha, a move that Goku uses in the  franchise.

Trivia

 * Aura Storm is one of Lucario's few moves that does not deal greater damage and knockback based on how much damage Lucario has accumulated.
