Using Gear 4 has a number of drawbacks for Luffy. There is a limit to how long he can keep Gear 4 active, as noted by both Luffy himself and
As powerful as Gear Fourth is, Luffy can't use it all the time. The technique drains him of both his stamina and his Haki. As such, he can only pull it out when he's certain he can win with it.
Luffy can use Gear 4th for a minimum of 20 minutes, as indicated when he used it against Doflamingo in chapter 785.
6 Gear Fourth's Debilitating Weaknesses
Due to revolving around the compression of his limbs, Gear Fourth requires Luffy to get up close and personal to his targets, making it not a great option for ranged attacks.
There may be no such thing as Gear 4th without haki. Haki strengthen his rubber so he can stretch for Gear 4th. Maybe without haki it isn't even possible.
3 Gear 4: Snakeman
All of Luffy's attacks in Snakeman are ranged and hit the target in an unpredictable fashion. The weak point of this form is that it sacrifices the extra defense that Gear 4 offers for additional speed.
The red shade of haki is formed because he is using his devil fruit to make the haki have rubber properties.
Luffy's greatest power-up to date is, undoubtedly, Conqueror's Haki coating. During his fight against Kaido, Luffy observed Kaido coating his weapon in Conqueror's Haki. After this realization hit him, he was able to use a crude version of this technique himself and could coat his fists in Conqueror's Haki.
In the fight against Kaido, Luffy finally tapped into what is his strongest transformation of all time and supposedly him at his peak – Gear 5.
1) Gum-Gum Bajrang Gun
The Gum-Gum Bajrang Gun is essentially the Gear Fifth version of the Over Kong Gun, using both Advanced Armament and Advanced Conqueror's Haki in its setup. One main difference is the sheer increase in the attack's size, which sees Luffy's fist grow to nearly the size of the island Onigashima.
With his devil-fruit powers, Luffy is able to manipulate his rubbery body into various forms, which he calls “Gears.” Currently, Luffy has managed to unlock up to five gear forms, and his fifth gear is known to be his peak form. He was able to unlock Gear 5 after awakening his devil fruit.
In addition, Luffy still has his standard weakness to cutting attacks.
Yes! Of course, Luffy's Gear 5 is the peak of his colossal powers. He can literally do ANYTHING with his devil fruit powers right now, as he transforms into the Sun God Nika when using Gear 5, making his devil fruit the strongest in existence so far.
According to Silvers Rayleigh, this is a very clever way to deal with enemies and it also enables Luffy to fly, which is yet another advantage that Gear 4 offers.
Luffy's Gear 5 is his strongest asset in One Piece, which is powerful enough to overpower the King of Beasts, Kaido. Although Luffy calls it Gear 5, it is actually the awakened state of his devil fruit.
The more he laughed, the better he seemed to fight. Throughout the clash against Kaido, fans could see him laughing even though he was fighting a high-intensity battle, which just goes to show how important it is to his character.
Kaido is one of the best fights that fans have seen in One Piece over the years, if not the best. The fight is, undoubtedly, the most difficult one that Luffy has fought so far. Kaido managed to defeat Luffy three times. For the first time, Luffy faced defeat against him Kuri and was thrown in prison.
The concept of power up Gears has been a core part of the One Piece franchise and allowed Luffy to take on the most difficult of foes. Fans speculate Gear 6 is inevitable – and with the series winding up to its conclusion, it could play a pivotal part in the final conflict.
While using Gear 5th, Luffy is able to extend his elasticity to inanimate objects. Luffy's devil fruit awakening allowed him to beat Kaido, who was considered the "Strongest Creature in the World." In his Gear 5th form, there are not many One Piece characters who can defeat him.
1) Nico Robin
Nico Robin, however, is undoubtedly the smartest amongst the Straw Hat pirates. She's the only survivor of the island of Ohara, a people renowned for their general intelligence and academic capabilities.
When he was a child, he was afraid when Garp would find out about his dreams of sailing as a pirate. He is wary of Nami's temper, as he thought whoever wanted to marry her is brave.
Having used his vast knowledge to create lasers, giant robots, and the Thousand Sunny's puzzle like architecutre, Franky has to have the most intelligent mind of all the Straw Hats.
In the anime, the user of Haoshoku Haki has a dark purple aura around him.
This is to relate to his Devil Fruit ability, the Mera Mera no Mi, or the Flare Flare Fruit. As such, the orange color of Ace's burning flames is also a big indication that his color is, in fact, orange. Furthermore, even his Devil Fruit is orange in color.

4 Armament Haki Subtype 5: Tribal Haki
Although much about this Armament Haki subtype (colloquially named Tribal Haki by fans) remains unknown, it is speculated that it allows users to combine their Haki with their Devil Fruit powers.
