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 Super Armor Frames while using this move, and it has one of the largest sweetspots of all the recovery moves. These two facts mean that Lucario has arguably one of the best recoveries in Brawl.
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.
In the Pokémon games, ExtremeSpeed is a physical normal-type move that always goes first, similar to Quick Attack, but twice as powerful.
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.
