This is gonna be a pet project of mine where I make a detailed analysis of what technique(s) in the One Piece world is perfect for one individual character at a time. Looking at things such as fixing weaknesses in a character’s fighting style, theorizing on potential abilities the user is not tapping into with their DF etc. All in an effort to try and get as close to the max potential for a character and things we may see being used by these characters when they reappear.
The Strawhats have been done to death, and I will do one of them every once and awhile (Probably not the DF users too much) but just in honour of the Year of Sanji that is on the horizon, I would like to start with the badass martial artist of the crew. Don’t expect many strawhats after the first few that I want to talk about, because like I said, they have been done to death. Alright that’s enough intro let’s get to it.
BLACK LEG SANJI
Sanji, the awesome kick fighter of the crew. Master of the Black Leg Style, and creator of the Diable Jamble technique, Sanji imo has always been a cool character who hasn’t reached his full potential yet. With the Year of Sanji on the way, that may start to change so he can finally reach levels where he can take on Kizaru at the end of the series, because that would be awesome.
Pearl in particular foreshadowed a LOT of Sanji’s current techniques and he’s easy to forget because of how long ago he was. He even had a technique that cloaked himself in fire. He may be foreshadowing my matchup with a Diamond fruit using Burgess at the end of the series. Yet another precious stone that can be used. So now that we have that out of the way, let’s get into the skills that Sanji will pick up
that are perfectly crafted to assist him.
1. RANKYAKU (TEMPEST KICK)
This is the martial arts version of the air slash that swordsmen use. And it is unique way of Oda giving martial artists, ranged techniques. This technique in particular is pretty essential for Sanji’s fighting style. It gives him range, and he specifically can draw even greater potential out of this move than we have seen so far because his entire fighting style is focused on his legs. He may already have the capability to use this technique.
What makes this technique particularly deadly in the hands of Sanji is Diable Jamble. Could he create a flaming kick slash? That is the question. On the surface the answer is no. To ignite the air requires a ridiculously hot heat source and one that is constantly producing heat.
We all want Sanji to get hotter, but spinning more, or spinning faster will never get you there. Friction is a very labour intensive way to generate heat. The more friction, the more heat that is lost to the surroundings. In fact, it is a very inefficient way. So even if Sanji were to spin a lot faster, initially he may gain some heat, but he’ll lose it just as fast. Not just to the friction, but also to the temperature gradient he would be creating between his leg (the source) and the atmosphere around him.
The hotter something is, the faster it loses heat to its environment.
Therefore, Sanji’s current method of generating Diable Jamble will eventually be antiquated, incapable of developing any further beyond its max point. And I’d say, not efficient enough heat wise to creating a flaming Rankyaku.
However, as for basic Rankyaku, I’d expect Sanji to be able to pull that off in his sleep.
So we have out first likely technique.
2. TAKING DIABLE JAMBLE TO THE NEXT LEVEL
Diable Jamble is an amazing technique. And its usefulness is largley overshadowed by the fire aspect. But where Diable really shines is transfer of thermal energy. Heat, is basically measured by how much motion is ongoing in a body of matter.
That’s why thermal durability is in many ways more impressive than physical durability. To be resistant to heat, one’s own molecules have to resist absorbing thermal energy from any heat source. Naturally, bodies made of flesh don’t have such impressive qualities. It’s why Diable Jabmle ate through Tekkai like butter, as that technique is the physical reinforcement of the body through extreme tensing. But Diable Jamble transfers thermal energy to its target, giving the atoms more energy that they have to move around more, forcibly undoing the tension Tekkai created. This is probably one of my favourite powerups any Strawhat has ever had it’s awesome.
However, in light of the activation limitations I outlined above, if Sanji is gonna reach a higher level of Diable Jamble, he will probably need to create a new way to activate the technique that doesn’t involve friction against the environment in any capacity (air or water). The best way would be somehow to generate the heat internally and let it radiate outwards. (Well the best way is to get some kind of DF, but I’m not going there. I don’t think anyone thinks Sanji is gonna get a DF). So how does Sanji create more intense heat for his Diable Jamble? The answer was just revealed in the recent Dressrosa Arc.
The practitioners of Hasshoken have a remarkable technique. Technically, it’s not even remotely possible physically without destroying yourself. What they have done, is learned to oscillate their molecules around a fixed position without losing form to such a high degree that they can can produce vibrational waves, that radiate outwards and cause the molecules of rigid objects like metal, to fracture and fall apart.
Anything that doesn’t oscillate well internally is likely to fall apart under the strain of these waves. In many ways it’s brilliant and might be the coolest martial arts in the series, behind Rokushiki. At least imo.
But what does this have to do with Diable Jamble? Vibrations. Vibrations don’t only produce force, high enough vibration produce HEAT.
If you think about it, heat is just the sensation produced by the motion of atoms of matter. Furthermore, heat is really impossible without two things; Matter and Motion. By vibrating, Sanji could completely change his Diable Jamble activation. He won’t have to spin at all. He’d just have to vibrate his leg and it will heat up, much more evenly and less wasteful as well. And he could keep the vibrations going at will, so he won’t be constantly losing heat with Diable Jamble after he activates it. After all, once the friction is done, the technique only last a short while after.
With this skill, and using it in his own way, Sanji will actually be able to achieve higher levels of heat, as he’d be able to produce a steady ignition source at all times so long as he could keep the vibrations going. While at the same time, when not needed, just adding vibrations to his regular Diable Jamble adds another layer of penetration that makes his attacks deadly.
This also gives Sanji a unique way of breaking down even the toughest of defenses. Through constant pressuring with attacks imbued with both heat and molecular vibration, every time his kick hits an object it becomes progressively weaker and will be almost guaranteed to fall apart. A full course of Sanji cooking.
This martial art is thus perfect for giving Sanji the skill to ascend to even greater heights both in his fighting techniques as well as haki. I’m 100% sure he will gain this skill.
3. HEAT AS HOT AS HELL’S FLAMES
How hot can Sanji then go with technique? How hot does he need to go? It’s an interesting question. But it depends the opponents he will face. If he has to beat Diamond, he would need to go past 3550 degrees celsius. In perspective the surface of the sun is around 5500 degrees celsius, so he’s not far off at that stage.
It would be amazing to see Sanji reach the temperature of the sun and melt the ground and shit as he walks. The sky is the limit. What we have to balance however is how does he avoid hurting himself with these techniques? Well, the only option is Armament haki, but special clothes may also end up being necessary depending how hot he goes to. We know that Marigold used her haki to protect her while she set herself on fire, so we can only guess haki would be involved in protection from the heat for Sanji.
Just a note on Sanji’s haki. Oda has taken the fun out of speculating on this area by basically confirming Sanji will specialize in CoO, which is great because that was my prediction all the way back during the break after chapter 597. To fight Kizaru however, Sanji’s speed needs to be absurd. Observation can only take you so far.
4. SANJI’S SPEED TECHNIQUE
It’s simple, Sanji has to find a way to use his immense leg strength to push the boundaries of some speed technique to a new level to take on Kizaru. Soru being the number one candidate with it’s acceleration technique of kicking the ground over 10 times in an instant. But what if you pushed that number even further. 20+, 50+ 100+ times at the starting moment could produced speeds well beyond what Soru does.
On the other end of the spectrum it could be something new entirely, that doesn’t use kicks. Maybe some kind of muscular manipulation technique that produces one big burst instead of multiple rapid ones. Like Urouge’s bulk up or Lao G’s cellular energy store thingamajig. Maybe this technique will be bolstered by Fighting Cuisine and strengthen the body to store that kind of energy. Either way, Sanji will likely be the fastest non DF user in the world by the end of the series. Which is mighty fine and I can’t wait to see it.
So we have CP9 techniques, with Hasshoken, and haki and new heat techniques all wrapped up into one. I’m sure you can tell I didn’t bother going in depth into things like Haki because it felt obvious to me at least where these skills were heading. It’s also too universal, you could lap it on anyone. Alternatively, I focused on the likekly more unique skills Sanji would end up acquiring.
Now we have all of compiled, what are you ideas on what skills Sanji will develop?
