Extreme Speed

Extreme Speed (, Godspeed), formatted as ExtremeSpeed in Brawl, is Lucario's up special move.

Overview
This attack consists of Lucario rushing at high speed 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. Lucario has a quick air speed while using this move, and it has a large, making ledge-grabbing easier.

From Super Smash Bros. 4 onwards, the distance traveled by Extreme Speed increases as Lucario's damage rises, with high aura granting exceptional distance. At 0%, the distance gained is comparable to Brawl's, but at 190% the distance gained becomes incredible, to the point where Lucario can easily overshoot the stage if it isn't careful.

As Lucario keeps Extreme Speed's velocity a second after the move ends, the move will grant even more distance if Extreme Speed ends in the air - a ground-hugging full aura Extreme Speed travels 3/4 of Final Destination, while an aerial Extreme Speed can cover more than its full length if the move ends in the air. This sheer speed can make the move especially difficult to aim while at high aura, and makes Extreme Speed a double-edged sword at max aura: Lucario can easily recover from anywhere offstage, but can as easily underestimate the distance it travels and shoot off the other side of the stage.

As of Smash 4, Extreme Speed deals damage to opponents only when the move ends, unlike in Brawl, where it dealt no damage. This gives the move some offensive capabilities, as it can actually KO if Lucario and its opponent are at 120% or more. However, the move now has two seconds of landing lag if Lucario ends the move in the air, making it incredibly unsafe if the opponent is nearby; this can be remedied by ending the move parallel to the ground or making Lucario hit the stage face-first, which cuts ending lag to half a second.

In Ultimate, unlike other special moves, Extreme Speed can grab the ledge after Lucario has grabbed the edge six times, which would normally not let the player grab the edge any more before landing or taking hitstun. However, this will not restore normal edge grabbing outside of Extreme Speed.

ExtremeHogging
ExtremeHogging is the use of Extreme Speed 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 left. By going over the lip of the ledge, still holding down, Lucario will almost instantly grab the ledge. If the player wants to go right, it's a little harder, since right-and-down must pressed diagonally.

Customization
Special Move customization was added in Super Smash Bros. 4. These are the variations:


 * 1) Extreme Speed: Default.
 * 2) Ride the Wind: Similar to the Brawl version. Increases Lucario's control and distance, but is slightly slower and deals no damage.
 * 3) Extreme Speed Attack: Removes the sweetspot and large knockback of the move, and is instead a multi-hit attack that is easier to connect with. Slightly less distance gained.

Use by other Pokémon

 * Rayquaza - Rayquaza may randomly use this move during the boss fight against it. Rayquaza will rush off of the screen, then breeze forward in one direction, dealing damage and knockback, also generating wind. On lower levels of HP, Rayquaza will perform this move 3 times in a row. Some characters must jump over this, while some can crouch under its hitbox. Rayquaza uses this in similar fashion to how it would in Pokémon Pinball: Ruby & Sapphire.

Origin
In the Pokémon games, Extreme Speed was introduced in Generation II as a more powerful version of Quick Attack; in that generation, it was the signature move of. It is a physical Normal-type attack with 80 base power, 100% accuracy, and a +1 priority in Generation II-IV and a +2 priority in Generation V and onwards, meaning it will usually go first if there is no other higher priority attack being used as well, regardless of the user's. In return for being exceptionally fast and powerful, this attack only has 5 base PP (can be upgraded to 8 max) so Extreme Speed can only be used 5 times unless PP restoring items are used.

Lucario can learn Extreme Speed by leveling up, and is one of the very few non-legendary Pokémon able to learn the move by any means.

Rayquaza can also learn the attack naturally by leveling up, and is instead one of the Dragon-type Legendary Pokémon along with Zygarde as of Generation VI to learn it like so.

In Generations II-V, the move's name was formatted "ExtremeSpeed" due to a 12 character limit, and this spelling is also used for Brawl. Since the Generation VI Pokémon games reformatted the move's English name as "Extreme Speed" due to increasing the character limit, the move's name was similarly changed for SSB4. Despite this, the official Miiverse posts pre-release continued to refer to "ExtremeSpeed" without a space.

The Japanese name of the move is derived by the term "Shinsoku" (神速), a Japanese term meaning "godspeed".

Trivia

 * In Brawl, if tap jump is disabled and the player performs Extreme Speed's ending on the ground, Lucario will be unable to perform it again until it jumps.
 * If the game is modified to run at a slower pace, such as via the Training mode or Slow Brawl, players can have considerably greater flexibility over Lucario's path; with proper manipulation, it is possible to allow Lucario to form double bends in its path.
 * Extreme Speed is one of two up specials that initially didn't do damage, but became able to in the next Smash game it appeared in. The other is Quick Attack.
 * Coincidentally, both are offensive Normal-type moves with boosted priority used by Pokémon.
 * As of Ultimate, this is the only up special move that's still affected by the grab release glitch.
 * It is also one of the two helpless-transitioning special moves to be affected by the glitch, with the other move being Wolf Flash.
