Black Leg Style/Diable Jambe

Diable Jambe is the latest addition to Sanji's original fighting style, where he uses friction to set his leg on fire, adding extreme heat to the impact of his kicks. In this form, Sanji, due to the high temperature, has more speed, more strength, and the ability to burn his opponents. While like this, he can light his opponent on fire. It is also later revealed that Sanji can utilize this with either his left or right leg. This technique has been shown to have adverse effects, if Sanji uses it for too long or too frequently he could cause serious injury to his body.

Techniques

 * Diable Jambe (悪魔風脚（ディアブルジャンブ）): In this technique, Sanji spins rapidly, causing his legs to heat up so much that they turn red. This was first seen being utilized against Jyabura to completely shatter his Tekkai. This is called Diable Jamble in the FUNimation dub, but in the Viz Manga, this technique keeps its original name.


 * Premier Haché (一級挽き肉（プルミエールアッシ）): Sanji does a running jump and kicks with both legs into an opponent's stomach rapidly various times, but Diable Jambe's heat greatly increases the power. This was first seen being used against Jyabura. Unfortunately for Sanji, it missed. This is called Premiere Hachis in the FUNimation dub, and in the Viz Manga, this is called Premier Hachisash.




 * Flambage Shot (画竜点睛（フランバージュ）ショット): In the air (sometimes several feet from the ground), Sanji kicks the side of an opponent's head with his foot (or the middle of their torso) and Diable Jambe's heat greatly increases the power, often with explosive effect. The target is usually kicked downwards, causing them to come crashing into the ground. This was first seen being used to finish off Jyabura, but had to use the other leg to deflect half of Jyabura's Jushigan, in order to "reserve" his flaming leg for the finishing blow. This is called Franpage Shot in the FUNimation dub, and in the Viz Manga and FUNimation subs, this is called Flambé Shot.


 * Extra Haché (最上級挽き肉（エクストラ・アッシ）): Sanji leaps into the air and launches a fierce barrage of flaming kicks, the light from the attack and the speed at which it is delivered makes it look like one big fire blast. This was first used against Moria in an attempt to retrieve Robin's shadow.


 * Frit Assorti (揚げ物盛り合わせ（フリットアソルティ）): A completely revamped version of the original Frit Assorti. Jumping high into the air, Sanji delivers three simultaneous kicks in three directions (left, right, and forward) while in Diable Jambe mode, resulting in flames spiraling towards the target at the point of impact, apparently powerful enough to deflect Oars' Gomu Gomu no Bazooka attack.


 * Mouton Shot (羊肉（ムートン）ショット): Sanji performs a Mouton Shot in Diable Jambe mode. This was first seen being performed for a three-way team combo, the San Tou Ryuu Gomu Gomu no Diable Mouton Jet Roppyaku Pound Cannon (along with Luffy's Gomu Gomu no Jet Cannon and Zoro's 108 Pound Hou.)


 * Venaison Shoot (野獣肉（ヴネゾン）シュート): Sanji, spinning horizontally in the air, kicks the opponent repeatedly in the chest and belly, finishing the attack with a powerful axe kick on the head with the speed, heat and strength of the Diable Jambe mode. This was first seen being used to defeat Scarlet during the events of One Piece Film: Strong World.

Team Combination

 * Santoryu Gomu Gomu no Diable Mouton Jet Roppyaku Pondo Cannon (三刀流ゴムゴムの悪魔風羊肉JET六百煩悩攻城砲): A combo attack performed by all three top fighting members of the Straw Hat Crew: Zoro, Luffy and Sanji. Zoro performs a 108 Pound Hō, while Sanji activates his Diable Jambe technique and delivers a Mouton Shoot, then Luffy uses Gear Second and fires a Gomu Gomu no Jet Cannon. The impact of the three techniques hits a single target simultaneously. This was first seen being used against PX-4. In the FUNimation subs, this is called Santoryu Gum-Gum Diable Mouton Jet 600-Caliber Phoenix.

After Timeskip
This is a list showing the attacks Sanji used after the two years training in Kamabakka Kingdom, before the Straw Hats' reunion. He also seems to be able to use Diable Jamble itself a lot quicker, requiring much less spinning to heat up his foot through friction. The fact that he was able to do it at all under the cold sea water and in mid-air should be noted.




 * Bien Cuit: Grill Shot (熟焼（ビアン・キュイ） グリル・ショット): A new technique learned after two years of training in Kamabakka Kingdom. Running at his target at incredible speeds (if done underwater, after using Blue Walk), Sanji will spin around slightly and deliver a strong back kick to the center of his target. This will burn a significant amount of the target (considering that it was used underwater, several thousand meters down) around the kicked area and leave a crisscrossed grill shaped burn. This attack seems to be an enhanced version of Diable Jambe: Mouton Shot. This was first seen underwater against one of the Kraken's tentacles.


 * Poêle à Frire: Spectre (焼鉄鍋（ポアル・ア・フリール） スペクトル): Another new technique learned after two years of training in Kamabakka Kingdom. After using Sky Walk, Sanji kicks repeatedly downward with his flaming leg, to take out multiple opponents. The way Sanji moves his flaming leg is very similar to the way Ivankov moves his head while using Ganmen Spectrum, which seems to be the reason why Sanji decided to put the "Spectre" word (which is French for Spectrum) in the name of this attack. This technique seems to be an enhanced version of Diable Jambe: Extra Haché, as Sanji kicks only with his flaming leg, not with the other. It was first seen being used against several New Fishman Pirates.




 * Hell Memories (地獄の思い出（ヘル・メモリーズ）): After closing his eyes and remembering his painful time in Kamabakka Kingdom, Sanji immediately becomes enraged, his whole body catching fire (the appearance he gains when in this state is very similar to that of the Thriller Bark arc when he found out that Nami was kidnapped by Absalom). He then leaps into the air and delivers a powerful kick to his opponent, setting their entire body on fire, and causing great damage. This attack generates an enormous amount of fire, even enough to encompass a giant opponent like Wadatsumi. This was first used to defeat Wadatsumi.

Trivia

 * Diable Jambe is a term used for referring to highly spiced dishes.
