GEAR FOURTH AND THE LAST 2 GEARS Theory

one piece manga 784

After chapter 783 and a slew of Gear Fourth theories, I decided to also make one. (LOL)

And I believe Luffy will reveal 2 more “Gears” in the future.

Gear Fifth and the “Reverse”.

I’ll just get straight to the point, here goes:

During the Enies Lobby Arc, Monkey D. Luffy invented 2 gears, namely Gear 2nd and Gear 3rd, to make a somewhat accurate guess on what Gear 4th would be, we need to look back and see how Luffy made the first 2 gears up and what’s the difference between the two.

First Gear (in a way) is Luffy’s natural fighting form, consisting of attacks named after “guns” after bragging to Shanks that his punch is as strong as a pistol.

Gomu Gomu No Pistol, Bazooka, Gatling Gun, Rifle, Rocket, Cannon….you get the point.

He also names his attacks after “weapons” namely, Axe, Whip, Sickle, Spear and other special things like Gomu Gomu No Storm (which he used against Crocodile), Fireworks (which he used against Captain McKinley’s troops) and Windmill (Against Moomoo when he fought Arlong)

Now, of all the attacks he used in his first form, its interesting to note the last 3: Storm, Fireworks and Windmill.

We all know that the basic Luffy have came from his fascination with pirates, and named his attacks with the weapon they used.

But the last 3 attacks are attacks he invented upon seeing or hearing something. Luffy is a battle genius.

He invented the Gomu-Gomu No Storm as either some sort of tribute to the drought in Alabasta or to Crocodile’s “sandstorm” itself.
He invented the Gomu Gomu No Fireworks after seeing the troops of Captain McKinley shooting Milky Cloud trails.
And he invented Gomu Gomu No Windmill (Pinwheel) after seeing Genzo’s pinwheel.

I brought this up because it applies to the logic he used with his “gears”.

Luffy invented the “gears” after being fascinated with the Sea-Trains at Water 7 and seeing the Elbaf Giants, and he acquired the method of those attacks from CP9’s Rokushiki techniques (specifically Soru) and from the Elbaf Giants he met at Little Garden.

Gear 2nd was him pumping blood to his veins in order to make him faster than his usual capabilities.
Gear 3rd was him expanding his rubber bones in order to imitate a limb of a giant.

And the last similarities is that, all his gears have “dangerous consequences” once used. Gear 2nd being him draining his life, and Gear 3rd making him slower than usual and turning into a smaller Luffy for a few minutes.

So if we review his gears, they have several similarities:

1. They are invented after Luffy sees something he takes interest into.
2. Luffy imitates the attack of other people he fought.
3. There’s a serious consequence for using it.
4. It modify his body past his limits. (for 2nd its Blood, for 3rd its his bones)
5. It’s Luffy using the properties of rubber.

And an additional hint: Doflamingo comended Luffy for his quickness but noted that he “lacked power”, and Gear 3rd is too slow to hit Doflamingo.

So we could assume the 4th gear is fast enough to hit Doflamingo, but is strong enough to hurt him.

So what do I think Gear Fourth is?

I believe Gear 4th is “Revenge”.

Yes, and it pertains to the “Recoil” or “Rebound” capabilities of rubber and how it can sustain “stress” and “vibrations”.

Basically, I believe that this gear is a desperation move, that’s why I called it “Revenge”. If you played Street Fighter 4, you might know the “Revenge Meter” right?

Basically, the higher the damage you received, the stronger your “Desperation Move” using the “Revenge Meter” would be.

And when I mean it’s a desperation move, I mean it’s a desperation move: Luffy can only launch this attack ONCE.

And it’s the reason why Luffy uses it as a last resort if the 2 first gears don’t work, and if he is beaten badly.

Luffy stores all the impact and stress in his body, from his other attacks and from his opponent’s attacks, and then launches it with a super-fast attack and him dealing all the damage back to his opponent tenfold.

So how did Luffy come up of this Gear?

King’s Punch.

Let’s not forget that Luffy is watching that fight, and let’s not forget that it was mentioned that King Riku’s punch is able to take down a Yonkou.

And it’s just King Riku, while it’s true that I believe the Fourth Gear is a “One-Time” desperation shot, and he got that idea from King Riku, I believe that Luffy got that idea of using “Vibrations” by being against these guys.

Don Chinjao, Sai and Boo.

And I believe that the Fourth Gear is so powerful that Luffy’s punch will literally explode which he got from fighting another coliseum competitor.

Cannon Ideo.

Summing it up, I believe Luffy’s Fourth Gear is a combination the King’s Punch, Hasshouken and Ideo’s Cannon Punch.

Who or what will pay homage for this move though?

Bellamy.

I believe Luffy will pay homage to Bellamy, he is also the reason why Luffy thought of this Gear in the first place, and the method came from King Riku, the Happou Navy and Ideo.

It’s very very meaningful that Luffy pays homage to Bellamy against Doflamingo.

What are the consequences for this move?

Basically everything, before Luffy use this move, he can’t attack….so he pretty much needs to defend entirely until he finds an opening.

After attacking, his whole body would be worn out and the inside of his body will rupture (good thing his body is rubber) but it still puts him in a really dangerous position since he is using the inside of his body to contain the impact.

Luffy basically is a walking Reject Dial in this gear, It’s basically Luffy’s version of Rokougan.

If he misses, he would be open for a very long time because his reaction time and his recovery from this attack would be very slow.

Why there are last 2 gears and what are they?

I honestly never even believed there would be a Gear Fourth until the recent chapter, but now it’s revealed, I sincerely believe that Luffy will imitate an engine (eventhough trains only got 2 gears. LOL).

Gear Fifth I believe would be Luffy finally having Elemental attacks. Remember when Luffy fought Enel? He insulated Enel’s electricity but who knows if he can produce it now that he took all of it?

He is already using a fire-attack, so I believe it would be more different than that.

As I said, Luffy will imitate an engine, and rubber can stand 2 elements: Fire and Lightning.

I believe that in the Fifth Gear, Luffy can freely produce Fire in one hand and Lightning in another hand, much like Blackbeard though he haven’t ate 2 devil fruits.

Remember Blackbeard’s abilities: Darkness and Vibrations.

Fire fights Darkness (figuratively and literally) and Lightning is another form of Vibration.

So basically in this form, Luffy could fight neck and neck with Blackbeard. I believe that not only Luffy can produce fire and lightning in his punches, he could also send shockwaves of lightning and fire if he punches the ground with it.

The drawback would be Luffy dealing damage to himself as well, not a long term damage like gear 2nd deals, but damage that he would feel while he is fighting in that moment.

Gomu Gomu No Stun Gun? LOL

Like this, basically:

Gear 2nd, Luffy imitated the piston of the engine, producing speed and steam.
Gear 3rd, Luffy imitated the wheels of the car, and inflated his bones.
Gear 4th, Luffy imitated the acceleration and brake properties of the car, producing a sudden burst of speed and power.
Gear 5th, Luffy imitated the heat and electricity of the engine, producing the ability to produce fire and lightning attacks.

Gear Sixth or Reverse
I believe Luffy will fully harness the Conqueror Haki’s full potential and he would basically be just in his normal mode, but his every attack utilizes the devastating power of Conqueror Haki’s wave.

One drawback: Luffy cannot control himself in this gear, and he risks the safety of him and everyone around him, and he can only uses for a short amount of time before it kills him.

Exactly when you reverse your car, minus the guide mirrors.

  1. Amazing!
    This is by far the most logic and justified theory. And i read thousands oft theorys in the last week. Some were bullshit, but this is gold.

    • Some people say that using the electricity was impossible. However, he as already show the ability to harness the use of electricity. This is shown when Luffy uses the red hawk underwater and everyone knows that it is impossible for fire to exist without oxygen. Which means that the only means that this happened was because he used electricity to separate the oxygen from the hydrogen in the water molecule to create fire.

  2. watermelon

    COOL THEORY ^_^

  3. It’s an awesome theory, you have some point that we should believe to this theory. An then if your theory really going happen I think you’re from the future, hahaha……

    I think drawback skill is same like other anime series, every main character have a forbidden ability and he can’t control it. But I think this section can make the story more interesting.

    thank you for share the literature, sorry for bad english and regards…

  4. Elizabello’s punch is the King’s Punch that can take down a yonkou, i think it’s not King Riku’s. well, the latter parts are slightly non-sense (fifth and reverse gears), but have good supporting statements. nice theory.

  5. king riku?? king punch?? u mean elizabello?

  6. Finally something worth reading. Thanks!

  7. Did you made a mistake about the King’s Punch? Was it really King Riku?

  8. If I didn’t know better I would say you’re from the future and has already read the mangas! Cool theory dude

  9. Gear 3 affect bones of luffy
    Gear 4 affect muscles of luffy
    Don’t invent other things.

  10. I think he learned gear 4th while he was training with Rayleigh. it’s not connected to any of the participants in coliseum.

    • NAVEED GUDDU

      Yes luffy said himself i invented gear 4 while training to handle big animals on that island

  11. It´s pretty cool what you said, but the one who uses “King Punch” isn´t King Riku, is King Elizabello II, I really liked your theory but I hope it isn’t just an attack but another “fighting state” but I recognize your theory is pretty good & it wouldn’t be a surprise the things are as you said, greetings from El Salvador, Latin America 😀

  12. LOL he can produce fire and lighting man you should stop watching fairy tail….anyway i don’t believe that you are right about the gears because you aren’t no one can but i agree with you that he will have and one more gear…gear 5 but who knows????only Oda can tell

  13. strawberry

    Just one thing, I think the gear fourth was invented at the time skip, not after he saw all the fighting moves in the Colosseum.

  14. SinOfGreed

    Luffy has already paid homage to Bellamy with Gomu Gomu no Spring Bang, also his Gears have nothing to do with Haki. Some (lately all) Gears are enchanted with Haki but they do not require Haki. If you think most of what you used as proof (you whoever mad this, you who believe this) are kinda BS (sorry but it is). All the Gears have 1 similarity THEY MAKE USE OF RUBBER’S PROPERTIES: Gear 2 used rubber’s streching and recoiling properties to make his blood flow faster, Gear 3 made use fo rubber’s strechign protperties, endurance and it’s weakness against sharp things to pierce his body with his teeth and blow air into his bones making his limbs or other parts of his body bigger. So it is logical that Gear 4 will also make use of rubber’s properties. Note: rubber isn’t immune to fire, it cannot be burned but the heat melts it…Gear 2’s flaming attacks come from Haki (Sanji’s Diamble Jamble is Haki too)so the only Element rubber can use is electricity. But why use electricity in Gear 4 and not one of RUbber’s other properties?

    Well here is the answer: When fighting with Blueno Luffy said that he had already created Gear 2 but never tested it, he also said the same thing about Gear 3 even though he did not use it then. Hmm, if contrary to the popular belief Luffy didn’t receive inspiration to create his gears from CP9, as they were already created before meeting them, then where did he get the ideas from? As we all know Luffy is a small genius when it comes to fighting. Now it is possible that he modeled the Gears after one of his Gear 1 moves: something like a prototype. The proof to back this up is that Gomu Gomu no Fuusen looks in an way similar to a Gear 3 move, it could be Gear 3’s model. Also Gomu Gomu no Bazooka’s movements look like the movement’s Luffy’s muscules make before Gear two, only in a larger scale. Bazooka was his fastest attack in Gear 1 (only the impact cause it took some time to get it ready) and as we know Luffy is a small fighting genius, he could have realised that if he minimized the scale of this talantosis he could make his blood flow at high speeds and become faster.

    Now we come to Gear 4: As you prolly noticed in the manga, during his fight with Don Chinjao they both used a Haki imbued hit that produced lightining…or so they say it is Haki…it could just be Luffy’s rubber body creating static electrism through friction, if that is true then we can assume that Gear 4 will use this (in a more advanced level) combined with some other thing (like A WAY to use it BETTER). If he uses the static electrism to create a small explosion (or boost his attack points) and combines Gear 4 with Gear 2 he will be fast enough AND strong enough to defeat Doffy.

    Also Dragon was once an Admiral named Admiral Shiroryuu

  15. hmm! not bad good creativity. but not good for one piece. you cant just create anything. it has to have some logic in the normal world understood? ie it should obey the natural laws! btw he cant just create lightning he is a rubber man and rubber is an insulator 😛

  16. maxinator92

    nice theory bro. the first part seems kinda logic, but the second part is a little bit far from one piece reality i think^^

  17. my expectation is that,
    since luffy has to fight blackB its inevitable! and we all kno the powers of Teach he has vibrations as well as darkness! luffy can stand the vibration to some extend as he is a rubber man and its effective unless teach uses a haki. i dont think BlackB uses haki. and if u recall the fight 2 years b4 in marineford! even after using the darkness power newgate still attacked him! ie there is a simple solution for countering that attack and i am prettymuch sure that luffy already has an idea about it! so i guess wat ever extra gears comes it will be to prevent or wage a fight/preparation to face blackB. 🙂

  18. moonriver 0712

    eh di wowwwww!!!

  19. The king punch was not king’s Riku punch. Its king Elizabello. But cool theory.

  20. what about luffy shrink his body like the tontatta and this will give him more speed and focused power

  21. Indiangamer007

    After a week everyone will know what 4th Gear is!

  22. car car devil fruit?

  23. Very Logical theory.

  24. Cool theory!! Also it’s Elizabello that uses the kings punch, not King Riku

  25. I hope there is no theory that will match to oda’s way of thinking!
    (sorry for my english!)

  26. Nice theory bro!~~

  27. Please don’t ever tell or mention that luffy gonna fight blackbeard, ’cause this is one piece not other manga, oda sensei always make something unpredictable for the one pice fans

  28. your theory is perhaps the most convincing one but do you actually think luffy would use something like a last resort move now? i mean so far they have been going through the new world with ease. and zoro didnt have much trouble with pica. because of this i think gear fourth is probably most likely another ‘mode’ that he can enter like gear second and third. maybe something to do with storing and returning vibrations but for a short period of time. the side effect could be that he would have to take direct hits to return strong hits and he would suffer from major internal damage.

  29. The first part of the theory is indeed interesting but it fails to hold on to reality, as in the reality strandard of that of the one piece world. Luffy producing electricity is just preposterous I like the vulcanization theory more because it would look cooler on luffy and somewhat makes sense because it is within the continuity of luffy utilizing rubber’s properties on his gears. I kind’a prefer luffy’s brawl fights using brute strength instead of seeing him fight like Natsu albeit using electricity. I would also like to point out that “Red Hawk” produces fire only as an effect of the initialization of the punch. The damage it done is not through the flames but from the speed and the strength of the attack itself. The flame is just a byproduct.

  30. This is a great theory,but you have not mentioned is experience in the war with white beard I think is fourth wil mainly represents that of is experience in the war,dew to the statement he say to dolfalmingo,that you’re the one block my way to advance.remember he fight against almost every big shot in the marine so think he use that experience to come with his gear fourth am not ruling out you’re theory but think this should mention.

  31. Youre theory was good enough but there is something need to think more before you predict the ability of gear 5 and 6 because of its very very long story.

  32. this theory is not going very deep and also there are lack of evidence to support gear 4th (and even 5th). moreover, I don’t feel luffy is heavily impressed by elizabello’s king punch to adopt it into his own technic.

  33. Nice theory but honestly I doubt that Eiichiro Oda would’ve taken such a long hiatus from One Piece to come up with something simple and kinda lame like that for Luffy’s Gear 4th. Luckly Luffy’f gear 4th wasn’t anything like your theory though.

  34. Luffy had said,when he is in amozone lily,luffy can only defeat the monsters at the island using gear 4th far before in dressrosa..
    So i believe he is not replicated his gear 4th from those people who just meet in dressrosa..

  35. i agree to B-Lee’s comment. He stated that he used fourth gear to defeat the monsters. Therefore, the theory of fourth gear is a little bit out. As to the other theories, it’s interesting.

  36. Very bad hypothesis (not theory). Here’s why:

    1) Gear 4th was invented during the time skip, so all the influences you listed make no sense. Also, none of the gears incorporate Haki as their core power, Haki is only a bonus.

    2) For rubber to conduct electricity (yes, everything can conduct electricity), the voltage would have to be so high that Luffy would quite literally melt or decompose in an instance.

    3) Only certain kinds of rubber are flame resistant, and Luffy is certainly not one of them given his brush with Akainu. Moreover, it has to be noted that fire and heat are not all the same thing.

    4) Gear sixth makes no sense based on what we currently know about his Haki and his gears. See point 1) above.

    5) It is much more likely that his next gear(s) would involve what Doflamingo called “Awakening”. This is as big a hint as you can get.

  37. GOOD THEORY!!! GOOD STATEMENT OF THE CAUSE AND CONSEQUENCES USING LUFFY’S GEAR. IT BECOME MORE APPLICABLE IN FUTURE EPESODE.
    BUT I ONLY DOUBT THAT LUFFY CAN USE ELECTRICITY. FIRE ELEMENT ALREADY USED LUFFY (BUT FOR ADDITION TO HIS BRAWL ATTACK) NOT LIKE NATSU. AND CORRECTION(HAKI AND HIS GEAR IS A COMBINATION TECHNIQUE. FROM THE FIRST HE LEARN HIS GEAR HE LEARN TO COMBINE IT TO HAKI. (REMEMBER RAILEY TRAIN AND THOUGHT HIM) CONQUERORS HAKI IS HIS SPECIAL HAKI. NO HAKI ATTACK NO DAMAGE TO THE HAKI USER. ITS A LOGIC. LUFFY’S GEAR CAN DAMAGE HAKI USERS ENEMY.
    I ALSO LOOKING FORWARD ON LUFFY GEAR 5 6 OR IF POSSIBLE 7 8 up to 10 NO REVERSE 🙂 I THINK GEAR 4TH INVENTED DURING HIS TRAIN AFTER 2 YEARS.


    (SORRY FOR WRONG GRAMMAR)

  38. Senin Jiraiya

    I second your theory about Luffy being a battle genius. He does imitate what interests him. However your theory of the gear fourth is not correct. He did not invent it in dressrosa. He had the trick up his sleeve the whole time even before the Fishman island arc. Luffy himself said that he needed gear fourth to fight the giant beasts on the island where he was training during the time skip. So gear fourh was there the whole time.

  39. The last gear theories make more sense when you look at the recent chapters. The Mink race is all capable of using a technique called “Electro,” and what does Luffy do when he explores the island? He gets in a fight with a Mink, who then clashes with Luffy using- you guessed it- Electro. With this theory in mind, I believe he will gather inspriation not only from Enel, but from the Mink race as well. I’d imagine he’d get a bit more exposed to it in the near future before he comes up with a clear idea of what the technique will be.

  40. I have a idea for gear seventh. It is when he uses his gum gum abilities to its full potential. Instead of just streching his limbs, he can also do it on his torso. He can take the bone from any part of his body and streach it so that it will resemble another limb which he can control, nerves, muscle and skin can be shaped to his need. This is like adding more cars to a train.

  41. It’s a great theory but there is only 4 gear (gear 2nd, gear 3rd , gear 4th and gear 5th)

  42. Yeah you did forget about the awakening because flamingo said awakening effects more than the use so some gear will most likely be about awakening

  43. Well to me he learned it with Rayleigh because when he was fighting doflamingo he was remembering his training and how he needed to take his powers to the next step. This is only my opinion
