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 (where Lucario will appear to "bend" through the air), 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, making ledge-grabbing easier. This enables Lucario to have one of the best recoveries in the game. Lucario's recovery is greater if there is a wall to cling to.
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.
ExtremeSpeed can be also be used to quickly grab the edge to edge-guard a player attempting to grab it. If the player uses the move, but holds down as the direction, Lucario zooms across the floor to the right. By going over the lip of the ledge, still holding down, Lucario will almost instantly grab the ledge. If the player wants to go left, it's a little harder, since he/she must press diagonally left-and-down. This is called ExtremeHogging.
In Slow Brawl, it is possible to double bend to avoid aerial enemies by bending left, then up, then right, or vice versa.
Origin
In the Pokémon games, ExtremeSpeed was introduced in Generation II as a more powerful version of Quick Attack. It is a Normal-type move with 80 base power and a +1 priority, meaning it will usually go first, regardless of the user's Speed. Template:Lucario Special Moves
