Extreme Speed



ExtremeSpeed is Lucario's Up Special Move. When used, Lucario stops for a brief moment, and then dashes in the direction chosen. It is possible to change directions during the dash, as well as being able to Wall Cling if it comes in contact with a wall, making it a very useful recovery move. However, ExtremeSpeed deals no damage, and as such, should only be used for either escaping attacks, or recovery. Lucario has low knockback while using this move, and it has a large sweet spot.

If tap jump is disabled and the player performs ExtremeSpeed ending on the ground, Lucario will be unable to perform it again until it jumps.

The Subspace Emissary boss Rayquaza also uses ExtremeSpeed as an attack, in which it dashes back and forth across the screen, dealing damage and high knockback, unlike Lucario's recovery only version.

Origin
In the Pokémon games, ExtremeSpeed is a more powerful version of Quick Attack, but in Brawl the move does no damage and does not travel as far as Quick Attack.
