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.
While Aura Storm is not an actual move in the Pokémon 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 Dragon Ball franchise.
