Forum:Straw hat haki

Zoro will have the conqueror's haki because that form of haki is supposed to be rare. If he's supposed to be the world's greatest swordsman, it's only logical that he should have it.

Some of the strawhat crew members will get haki, but not all. Seeing as it will be pointless and somewhat impossible for some of them to have being in their respective locations they are stranded on. Luffy is directly learning haki from Rayleigh and we've eall known he will be definetly be using haki of armaments in combination with his existing fighting style. Zoro has already been somewhat using haki but does not realize it and has very little controll over it, an example would be him fighting Mr.1 and he said "I didn't dodge the rocks, I just knew where they wouldnt land" seems like a perfect example of haki(color of observation) and cutting through a steal person and than later on cutting some stuff made of material as hard as steel later in the series just indicates hes imbueing haki with his swords but just doesnt knobw what it is yet. In some speculatoins I've heard people say Zoro will also get conquerors haki too because of people backing off from fighting him earlier in the series, but I am pretty sure that was entirely due to his reputation of being an "Demon Swordsman" which is only going to be exhagerated a bit with his new "tripple zoro" technique he does. Same goes for Sanji hes able to kick and destroy stuff that a human leg would normally would be injured trying to hit. He is most likely subconciously using a very weak form of "haki of armaments", and seeing as he is currently amongst one of the most powerfull forces in one piece it is safe to assume that they know how to use haki if they've managed to maintain their status as a formidable power, and sanji will improve on his fighting in addition to the food recipees he is going to learn to continue being competitive with zoro. With Usopp it is a bit difficult to say whether he will learn haki or not, he is currently on an island with a mysterious warrior whom we do not know if he knows how to use haki or not but does seem to have a very limited vocabulary. To escape from his current predicament Usopp will definetly have increased physical strength and speed and possibly a combination of color of observation and haki of armaments to improve his shooting abilities and attacking from range.

As for how and why members of the strahat crew wont learn haki. Take Nami for example almost everyone says she will have color of observation to help her better predict the weather, but the problem is how much better can she get? she already appears to have frightningly accurate ability to predict weather before most people even know something is going to change in the weather. She is going to be studying weather on the sky island which only leads me to believe she will have a broader understanding of how the weather works especially in the new world. As for her combat abilities I cant really see her using haki(wouldnt suit her style and would be a bit overkill), I can see her improving her currently staff to be more weaponized with nature based abilties. I am certain she will be using the "wind knot" that she combined with her staff to stop a storm in the animated series(I am not sure if it was in the manga aswel), adding in wind based powers in addition to creating clouds(I would assume she can make them faster combined with wind). Franky has never used anything that even remotely hints towards haki and he is on the island with research created by the scientist who designed the pacifista(who use advanced laser weapons but no haki either. I would assume franky will have a more weaponized and advance body at the end of two years(akainu's lazer powers like how the pacifista use it), would be a great addition to frankies already existing machine gun, launching a fist on a chain, fire breathing and a powerfull air blast. Mechanical tools built into his bodily that come out and repair him in tight spots wouldnt be too bad but may be overkill if he gets them.

Last three crewmembers being chopper, brooke and robin, in their case makes it a bit difficult to speculate. Brooks currently musical ability to put his enemies to sleep currently is just how he plays music and even with that his main attack is the sword which he makes it look like hes playing the violin with and strikes down his opponents with the sword than resumes playing the violin. I would imagine either he will figure out how to cut solid objects with his sword like zoro has already shown he can do or train under zoro to become stronger, he was worried about being less usefull than the rest of the crew when he first joined and I can only imagine that thought has gotten stronger in the back of his head with the crew being completely beaten by kuma, akainu and his sidekick. Chopper does not seem like the one whos interested in inflicting physical damage on other people or fighting in frontline but seems to fight when the crews in tough spots and is pretty good at it but uses his transformation abilities mainly. He was last seen hitting the books and quoting "I will become a moster if I have to in order to help luffy", I assume he will be improving his medical techniques and perfecting his rumble balls so he can transform into giant antler monster at will and actually controll himself instead of becoming a mindless monster. Now that ability would be overpowered if used constantly but during cp9 saga other crew members pointed out that if chopper remained in his giant form destroying stuff that may take a too much of a toll on his tiny body to handle which may remain as a weakness for that form to keep his power in check. As for Robin, its hard to say if she will get haki or not. Her current powers let her create duplicates of her body parts on surfaces or other peoples body, I cant really imagine haki mixed in with that. She is currently going to meet dragon but I havently seen any indication shes going to train with him seeing as the revolutionary army was looking for her(most likely because they NEED her for her ability to read ponoglyphs). If she were to learn haki I can actually see all three types mixed in with her powers, conquerors haki to just knock out a mass of enemies in addition to or using a substitute for her currently ability to attack a group of people. Color of observation, detect enemies and controll her blooming power out of sight so she can fight them before they ever get to her. Haki of armaments would be a perfect way to upgrade her current powers to allow her to continue using them in the new world even against haki/devil fruit users. Realistically I think shes just going to learn to bloom her entire body to create "Robin Clones"...

__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

I believe that each Strawhat member is going to get some form of haki after the 2 year skip. Raleigh said that haki could be used in different unique ways. I think because they will not get direct training, the other Strawhats will learn about the Haki later on or during the course of a hard battle.

Luffy: Since he is getting direct training I believe he will have a basic concept on all of them but the one that he will probably gravitate towards will be the armor one to hit logia type users.

Zoro: Zoro will probably learn how to put haki on his swords. The air slicing techniques will probably become extra strong and hurt logia types.

Sanji: Haki imbued kicks. Sort of obvious

Nami: I think her ability to basically sense the weather is a form of haki in and of itself. The haki where you can sense your surroundings and the next persons move. This makes her able to dodge opponents better too.

Ussop: He will be able to put haki on his projectiles like the amazons. I also think that Ussop will only be able to use his haki atttacks will he is Sogeking.I think Van Augar uses haki to attack from farther away because of him hitting that seagull and knowing that it didn't die. Ussop could get that too maybe

Chopper: Maybe he can use a form of haki to tell what is wrong with someone without examining them. This will make him a far better doctor and he can find a person's weakness easy.

Robin: Use the haki to sense people far away and use her attack on them from a far greater distance.

Franky: I don't know about him, he will probably just have a whole new array of weapons to use.

Brook: Seeing Scratchman Apoo attack Kizaru made me think that maybe Brook can infuse haki on his music and cause blades. This will also explain how he gets out of that cage. It will be cool to see Brook being able to cause illusions with the music he plays. He already can make people sleep, maybe with haki music he can affect what you see or make you dizzy by attacking the inner ear.

This is pretty good.

I agree. Though I don't really think I would like for all of them to learn haki, I think this way is pretty cool, rather than having them know one of the colors of haki, have them focus on one of them and infuse it with their specialty. I could absolutely see Usopp learning how to infuse haki into bullets or weapons, Robins color of observation to find people and attack from a great distance and Chopper's color of observation to figure out what's wrong with somebody is genius. Galcion 17:33, September 11, 2010 (UTC)

Yeah i agree with you too.

I dunno, I feel like each member will get good at what they need to be good at (i.e. their role in the crew) first, and Haki and other abilities will come secondary. Of course Luffy is gonna get a great deal of training of his already-awakened Haki, Rayleigh pretty much said it out loud. However, if you look at the others, they're already in positions in which they're already suited for improvement of their specific field.

Zoro is stuck on an island and training with Mihawk, the greatest swordsman in the One Piece universe. Nami is at Weatheria, the weather capital of the world. Usopp is learning to become a mighty warrior as he fights alongside Heracles (who was named after a mighty warrior himself). Sanji is in the Kamabakka Kingdom, where the residents not only know diesel kickboxing techniques, but can cook up a darn good dinner as well. Chopper is on an island that has one of the most massive libraries we've seen, as well as exotic rainforest-esque plants that could be potential medicines. Robin is doing God-knows-what, but it involves the Revolutionaries so it's gotta be important. Franky is at the most technologically advanced location in the One Piece universe reading up on a mysterious professor's blueprints. And Brook is a traveling performer. (Yeah, that one's kinda lame, but he's still refining his skills as a musician.)

Anyway, I don't think each of them will develop Haki, because if every single Strawhat has it, it'll lose its coolness. If anyone else, I'd have to say Usopp is the most likely candidate, as his training is closest to what Luffy is going through right now (sans the rapidly changing climate). 2xN 23:55, September 11, 2010 (UTC)

Just because you get a color of the haki doesnt mean that its going to be the same for everyone. Haki is their ambition, and I think that the Strawhats are the most ambitious to reach their goals. Brook refining his skills as a musician is all well and good, but Oda isn't gonna give them this time period to just improve on what they are one of the best at. Naturally they will get stronger, the main focus is to keep the manga going by making them efficient in their fights. As their role on the ship, that just makes it more realistic as to how they travel the New World. Their personal goals are now second to Luffy's goal, and in order to make his happen they must become stronger fighters too. Also Sanji is not just learning how to cook a good dinner, but its food prepared in a way that gives the user energy and muscle building supplements, maybe the Okamas are able to infuse haki into their meals.
 * Truth be told, I don't really wanna see the use of Haki for everything, cause then it gets way overplayed and again, loses its coolness. 2xN 20:07, September 12, 2010 (UTC)
 * Yes.I dont want haki to overplayed too.I mean maybe the "monster trio"would know some sort of haki.Even usopp and nami.But come to think of it even not the strongest people have haki.,Hitori uses haki Colby have Haki,almost or all Kuja tribe have haki.So not agreeing with every strawhat have haki here is what i think which strawhat won't have haki.Chopper learns how to control his monster form.robin can't think of any both robin and dragon seems so mysterious.franky learn or try to build some body parts with seastone insert that way his punches can hurt any devil fruit power,and Brook to me he is already quite strong but he always space out and talk about his skull joke he probably learn how to hypnotize with his music.with learning how to stand in certain angle probably he will now concentrate more on battle and not skull joke.this is my opinion.U guys can hate it but this is my thought.waddupwes.Awesome!Awesome!
 * Just my opinion, but I wouldn't wanna see Brook's "skull jokes" be compromised for improved fighting ability. 2xN 21:08, September 13, 2010 (UTC)
 * When the show first started there were hardly any devil fruit users, but as the show progressed, more and more users started appearing. Whenever a new enemy appeared them having a devil fruit power didn't mean that it was "overplayed" but they were different. Their powers were incorporated with their fighting style becoming something different entirely.
 * What I am trying to say is that devil fruit powers were a major thing in the Grand Line but in the New World that is not going to cut it anymore. Haki will be the main thing there and in order for Luffy to become Pirate King, him and his crew must be able to overcome haki users with their own haki.
 * I do admit that it will be boring if everyone uses haki in the same way but if they use it with their own fighting styles in uniques ways it will be interesting to see. I don't want them to learn it after the 2 years but by the end of the New world or close to the end I want them all to have something to combat haki and logia users.Kujokilla 23:35, September 13, 2010 (UTC)Kujokilla
 * At the risk of sounding like I'm riding Oda's dick, I think the core reason there were so many Devil Fruits in the Grand Line is because that's about the same time Oda started focusing most of his time and energy on One Piece, and his creativity and imagination went overboard. Who else but Oda would create so many super-powers that could only be used by one character each (not to mention a whole crap-load of characters)? The thing with Haki is it can only be divided into so many categories. If (what I assume to be) the entire second half of the series consists of every character using only that one super-power used in three, maybe twelve different ways, the creator's mind is going to explode. Of course this is all theory. Bon-boy and Croco-boy 05:15, September 16, 2010 (UTC)

 * Luffy- Yes, Duh, & OH MY GOD of course he gets Haki.
 * Zoro- I'm surprised at this, but I think his opinion of using Haki could go either way. ("Heh... now I can get stronger/ it interupts with TRUE swordsmanship.")
 * Sanji- Same reasons with Zoro. ("Tsk... now I know I'm stronger than that marimo/ I don't need it to become stronger")
 * Nami- I like the idea of Nami using Haki to learn better how to know her surroundings, and I aprove the possable development of it, but I don't see her learning it in her current situation.
 * Usopp- Definately. He is in the perfect situation to learn something like Haki, and he could utilize it well with his weapons and tools. But will he get Haki as well as the other training and
 * pop greens from Heracles?
 * Chopper- I disaprove of Chopper using Haki. I don't think it's a good match. But I do like Chopper using the herbs and plants on his island to make a more effective and controlable
 * rumble ball. Possibly a longer time of use!
 * Robin- Seriously? Who the hell knows what could be going on with her and Dragon?
 * Franky- No Haki please. Just becoming wicked stronger with way cooler weaponry.
 * Brook- Like Zoro and Sanji, I don't think that brook should be using Haki incorporations into his musical based attacks. He should definately use variations on those though. I could also
 * see him getting training of sorts from the long arm tribe due to sparring for entertainment.
 * My thoughts on who should or could get Haki in the strawhat crew. Feel free to disaprove or agree.--Jety Lefr
 * Like I said before, Usopp is the one I see most likely developing Haki. And I do agree with Nami as well, and you raise a good point with Robin and her workings with Dragon. There's one theory I'd like to bring up with Zoro and why he wouldn't particularly need Haki (if this theory were to be true.) He has developed the ability to "hear the breath" of his targets, being able to cut through things like steel, and I wonder if it's possible that this ability could be applied to fluid elements (i.e. Logia users.) Imagine if Zoro were to slice through a Logia user, and when said user reforms himself, he has a cut/gash where Zoro sliced him. This would not classify as Haki, which solidifies a fruit-user before/during the attack is performed. I know there's more to Haki than just "hitting Logias", but if Zoro were to have this ability, he wouldn't need another brand of Haki in addition to it. Bon-boy and Croco-boy 16:05, September 19, 2010 (UTC)
 * Luffy - Known to have learned Haki by now. I don't actually think he mastered it yet personally (he could have just learned the basics of how to use it and that was all Rayleigh could really show him, with true mastery having to come about through practice in battle), but it's possible he's a full Haki master already. We'll know soon. If he just winks the fake SH's into unconsciousness it's a safe bet he's a Haki master now.
 * Zoro - If Mihawk is a haki users (Which he might well be.) Zoro may have picked up Haki. If so he'd favour Observation Haki. (but could use both.)
 * Sanji - Probably wouldn't have picked up Haki (yet?), but he'd make a good user and so might end up learning it. If/Once he learns it he'd probably favour Armaments Haki. (but could use both.)
 * Robin - Might very well have learned Haki with the revolutionairies. Because as powerful as she is, what other way could she be upgraded? Snap someone's back or neck even faster then a few seconds?
 * Franky - Doesn't need Haki, and wouldn't have any way to learn it. I think his Vegapunk tech will make up for lack of Haki. (And may very well even contain anti-Logia weaponry! I wouldn't be surprised either way I guess.)
 * Usopp - Probably not, although his arsenal may one day include things to make up for lack thereof. Actually it possibly already does. (Kizaru vs Flashdial could turn out quite entertaining.)
 * Chopper - Seems a poor match for it.
 * Brook - Will have music-related abilities instead.
 * Nami - Won't have learned Haki, but weathercontrol is massively powerful as an ability anyway. (That could be Logia level of destruction, but much more versatile with all the type of weather and natural disasters out there.)
 * An Luffy seems to have fully mastered Haki, judging by the latest issue. (or at least he DID wink the fake SH's into unconsciousness.) I do hope it won't make him overpowered though. Whilst the fake SH's will (and should) be an easy opponent for the real thing, The New World should be a challenge for him. I don't think Conqueror Haki or Armaments Haki would be a risk for making Luffy overpowered per se. (Conqueror only seems to really work on low-level mooks anyway, and Armaments will just give him a necessary offensive upgrade.) But Observation Haki... well... if he can't be hit by non-Haki users, because he can see all the hits coming, then the New World had better be full of Haki users or Luffy's fights wouldn't be to interesting. But eh, I'm not to worried. I'm sure the New World has plenty of powerful opponents, and I'm sure some of the old opponents have gotten stronger too.
 * I think that we might see luffy mature a bit so he doesn't fight all the uneccesary fights and let the weaker members fight. I also think that ussop being able to enfuse haki into his projectiles is a great idea and would really affect the crew, at the moment he is using pop greens, but surely these would run out eventually and since he can't get them anywhere else he will become a lot weaker. however if he can enfuse haki with the projectiles he wouldn't have to waste the popgreens on weaker enemies.#
 * I think that the reason why ussop will not run out of popgreens is because as they are a plant and a seed he is growing them on the ship and resupplying all the time since as we know they grow really quickly.
 * Obviously Luffy is a Haki user and by training with Rayleigh, he now knows about it and knows how to use it along with his fighting style. It's only a matter of time that he masters every kind of Haki. Zoro might already have Haki since he trained under Mihawk, a Haki user himself. If not, sooner or later he has to develop Haki since he's the crew's 'champion'. If he's gonna continue being the Straw Hat's top fighter (of course only Second to Luffy, the captain), he has to have Haki.
 * Sanji and Robin are the next two that MIGHT learn Haki. Sanji may learn Armament Haki for an offensive upgrade since he doesn't need any kind of Haki for his cooking (since he already knows the recipes for the Attack Cuisine). Robin might learn Observation Haki (She might have already learned Haki from the revolutionaries but has yet to be revealed) since it coincides with her "goal" and her attitude.
 * I don't think Nami, Franky, Chopper, Brook and Usopp would learn Haki mainly because I cannot see them needing it. It would be a big help, sure, but having all of Luffy's crew learning Haki will just make them uncool/too strong. They might as well take on Marine Headquarters again. Instead, they will get stronger/better in their respective fields. Nami, a better navigator, better weather prediction and better Cartographic skills; Chopper, more rumble ball transformations and better understanding of medicines; Franky, more weapons in his body and customization of the ship; Usopp, a better sniper than his dad, better inventing skills; and Brook, well I'm really not sure about his abilities but he might develop a skill/power infused in his music.
 * I am psyched up for that 10th member though.
 * -StrawhatBirdy
 * You say that you can't see Nami, Franky, Brook and Ussop needing haki yet surely the power of armament for ussop would be a great help as his projectiles' power would be greatly increased.
 * Well, yes that could be also true but the power of Usopp lies in his new bullets, quick wit, and with the training he got during the time skip (not counting the battle experience he got during their adventures). It is possible that he (they) may learn haki but I think now (nor the near future) is not the right time for them learning all of those. Maybe when the Strawhats face a bigger challenge? The impending battle between them and the Blackbeard pirates? Who nows? Time will tell. It's just fun speculating. :)
 * -StrawhatBirdy
 * At the moment only Luffy has Haki, that much is clear. And it's likely he'll be the only one with Colour of Conquering. (If anyone else has DOES have that it'd probably be Zoro or Robin, but I think it's just Luffy. Zoro however MIGHT have it, if he's meant to one day exceed Rayleigh (who does have that ability and had a similar position to Roger as Zoro has to Luffy) Robin is less likely still, but if anyone else'd have it I say her, because she's shown a very strong will, and I think a plot point was made out of that.)
 * However either way, I could see Zoro use Colour of Observation one day (Which I think Mihawk may very well use as well (given how he can bounce bullets abd buggy bombs off his swords so easily.) And Sanji and Usopp maybe Colour of Armaments. (Especially for Usopp I think it'd fit, although if he gets a haki upgrade I'd expect it to be late in the series.) For Sanji I don't think it's particularly necessary, it might just be a natural result of him forever trailing behind Zoro. (I definitly don't think they're equals myself, Sanji I see more as the well known role of the more hot-blooded somewhat weaker rival (to Zoro.) (I also incidentally think this is why Franky seems to have been nerfed slightly since his initial introduction, when he was easily kicking the crap out of Blueno (Who kicked the crap out of Sanji earlier, but then later Franky's having some trouble (Although admittedly mostly due to being low on cola and being knocked into the ocean, and not because Fukurou was particularly strong.) with a guy weaker then Blueno and Sanji's somehow (Well by setting his leg on fire I guess) beating someone much stronger then Blueno. Why? To keep Sanji a believable rival for Zoro I assume! Wouldn't really work well if Franky was suddenly inbetween them strength wise (Although I do think Franky's much closer to Sanji then most people seem to think, powerwise. (just with different strengths and weaknesses.)
 * Anyhoo, I still like Sanji mind you. (just think the CP9 arc had some asspulling in his favour. (Although hey, at least he looks cool with his leg on fire... so, not a big deal.) And I could see him get haki because Zoro might well get it. I don't see it really for any of the other Straw Hats, but who knows. For all we really know it turns out they all in the end have Colour of Conquering, because they where a special crew of DESTINY!!! It's really all up in the air. All we know for now is that Luffy is the only one who can use Haki. And for all we know it could also be that it stays like that and none of the other crew ever gain Haki. It's all speculation. But if I had to pick crewmembers I think are likely to get it I'd say Zoro, Sanji, Robin and Usopp. (In no particular order.)

 * Anyhoo, I still like Sanji mind you. (just think the CP9 arc had some asspulling in his favour. (Although hey, at least he looks cool with his leg on fire... so, not a big deal.) And I could see him get haki because Zoro might well get it. I don't see it really for any of the other Straw Hats, but who knows. For all we really know it turns out they all in the end have Colour of Conquering, because they where a special crew of DESTINY!!! It's really all up in the air. All we know for now is that Luffy is the only one who can use Haki. And for all we know it could also be that it stays like that and none of the other crew ever gain Haki. It's all speculation. But if I had to pick crewmembers I think are likely to get it I'd say Zoro, Sanji, Robin and Usopp. (In no particular order.)
 * Well, yes that could be also true but the power of Usopp lies in his new bullets, quick wit, and with the training he got during the time skip (not counting the battle experience he got during their adventures). It is possible that he (they) may learn haki but I think now (nor the near future) is not the right time for them learning all of those. Maybe when the Strawhats face a bigger challenge? The impending battle between them and the Blackbeard pirates? Who nows? Time will tell. It's just fun speculating. :)

 * At the moment only Luffy has Haki, that much is clear. And it's likely he'll be the only one with Colour of Conquering. (If anyone else has DOES have that it'd probably be Zoro or Robin, but I think it's just Luffy. Zoro however MIGHT have it, if he's meant to one day exceed Rayleigh (who does have that ability and had a similar position to Roger as Zoro has to Luffy) Robin is less likely still, but if anyone else'd have it I say her, because she's shown a very strong will, and I think a plot point was made out of that.)
 * However either way, I could see Zoro use Colour of Observation one day (Which I think Mihawk may very well use as well (given how he can bounce bullets abd buggy bombs off his swords so easily.) And Sanji and Usopp maybe Colour of Armaments. (Especially for Usopp I think it'd fit, although if he gets a haki upgrade I'd expect it to be late in the series.) For Sanji I don't think it's particularly necessary, it might just be a natural result of him forever trailing behind Zoro. (I definitly don't think they're equals myself, Sanji I see more as the well known role of the more hot-blooded somewhat weaker rival (to Zoro.) (I also incidentally think this is why Franky seems to have been nerfed slightly since his initial introduction, when he was easily kicking the crap out of Blueno (Who kicked the crap out of Sanji earlier, but then later Franky's having some trouble (Although admittedly mostly due to being low on cola and being knocked into the ocean, and not because Fukurou was particularly strong.) with a guy weaker then Blueno and Sanji's somehow (Well by setting his leg on fire I guess) beating someone much stronger then Blueno. Why? To keep Sanji a believable rival for Zoro I assume!

I know this discussion is fairly long but I have thought about and in my opinion i think all the Straw Hats may learn Haki, some may know more than one.

First of I think Zoro maybe the other Straw Hat who'll know all 3 types because with his strength and willpower combined and his determination and dexterity as well, he seems like a fairly well rounded fighter who much of represents Reyleigh's role on the Jolly Roger crew with the exception of crewmember title.

The next I think Sanji with know the color of armaments just because his attacks are purely physical so he doesn't require much brains when he's in a battle so all he needs to focus on is making his kicks more powerful which making sure he can attack a DF user.

Usopp I believe with learn both the Color of Armaments and Color of Observation. As a sniper, Usopp can use both well to find other Snipers and to make his shots much more powerful. I think he and Van Auger are going to get into an epic sniping battle later on and it'll be pure Haki that decide the battle instead of the skill of sniping(since both prove to be very well at).

Robin i believe will know both colors as Usopp as she knows surprise attacking so use both to predict enemy attacks and to attack them down without touching them maybe key.

Nami with learn Color of Observation as she is a Navigator and weather girl. She can use the foresight of impending weather danger to her advantage as well as knowing what her enemies might do.

Chopper with know the color of Observation since his Rumble balls do much of the work for him, that type of Haki would compliment his forms especially his brain point.

Franky I think is a Color of Armaments since he can fire bullets and the such, he can use the form of haki to improve his attacks.

Brook finally I believe with know the color of Obervation only because he is a speed type swordsman, so when he's moving fairly fast with his fencing technique, he can foresee any attacks that could threaten him and quickly counter.

Just my thoughts, I think all the Straw Hats will know haki at some point- Langland

Sorry for a double post. But seeing just recently in chapter 334 how Robin, Zoro, and Sanji knew what haki is. I have a feeling that perhaps it may be confirmed that one of them may have haki. Also seeing that Sanji is a bit jeasous of the Kings Disposition Haki that Luffy has might also hint that Sanji may know how use Haki. Even with the way things have turned out, I still believe the other Straw Hats will learn Haki down the road too. - Langland
