Note that I don't take credit for creating this set (it's existed for awhile now). I'm not entirely sure who did, though.

[SET COMMENTS]
<p>Of all the sets Lucario can run, this is perhaps the one with the most destructive potential. The power this set wields is frightening - after a single boost, many walls that don't resist Fighting can be defeated in one blow with a little help from Stealth Rock or a layer of Spikes. For example: </p>
<h2>Damage Calculations</h2>
<pre>Close Combat vs Max HP/Def Skarmory 85.03% - 100.30%
Close Combat vs Max HP/Def Bronzong: 96.15% - 113.02%
Close Combat vs Max HP/Def Hippowdon: 76.43% - 90.00%
Close Combat vs Max HP/Def Forretress: 80.23% - 94.63%
Close Combat vs Max HP/Def Donphan: 82.81% - 97.40%</pre>
<p>Extremespeed decimates powerful-but-frail sweepers like Azelf, Infernape, and Dugtrio, finishing them in one hit before they can touch you. Crunch destroys Dusknoir and heavily damages Cresselia (possibly delivering a OHKO depending on how defensive she is). Bullet Punch might seem redundant when combined with another priority move, but it allows you to hit several threats like Gengar, Mismagius, and Aerodactyl, dealing near-KO damage to the two ghosts (which will always be fatal when combined with Stealth Rock unless they're running more than 4 HP) and easily beating the prehistoric bird. Stone Edge gives you a weapon against fliers and scores a crucial OHKO on Bulky Gyarados.</p>
[Other Options]
<p>Surprisingly, there aren't many other useful options. Lucario can Calm Mind for one, but the Choice Specs set hits harder faster. Choice Scarf Lucario with Me First is a nice idea, attacking the enemy Pokémon with the same move with its base power multiplied by 1.5. You can use Life Orb Lucario for a mixed set or if you utterly despise predicting, but focusing on one stat usually lets you hit harder. You can use Hi Jump Kick instead of Close Combat if you hate Close Combat's 8 PP and its lowering of your defenses. For Specs Lucario, you can use Psychic to hit Heracross, who otherwise resists all of Lucario's moves except for Shadow Ball. Flash Cannon is a decent option to hits things neutrally, but Steel as a rule has poor type coverage. Hidden Power Ice is an option on the physical sets to get rid of Gliscor.</p>
[EVs]
<p>In general, maxing speed and whichever attacking stat you're using is the best option. A slightly bulkier set for the All-out sweeper is 252 HP / 96 Def / 136 SpD / 24 Spe with Adamant nature and Leftovers, which makes better use of Lucario's numerous resistances and gives you some extra durability when setting up.</p>
<p>Most of the sets can run Jolly or Timid to get 306 Speed, outspeeding threats like Salamence and Electivire who outspeed you otherwise. However, Modest is required on the Specs set to 2HKO Blissey.</p>
Good? Does it need anything?
