To say that Luffy's current strength is definitely second only to the legendary pirate of the imperial character, even in the latest plot, it is also "five and five open" with Kaido. The reason why Luffy can have such a strong strength is naturally inseparable from the blessing of his own domineering. As we all know, Luffy's domineering teacher is "Pluto" Reilly, but many Hemi don't think so. Recently, there was a picture circulating in the Haimi circle, and when I saw this picture, I learned that Mr. Reilly was a "wrong person", and the really good teacher was still these three.
Although Luffy followed Reilly to learn about the three-color domineering and can use it in actual combat, he is slightly inferior when he encounters a real domineering master. In fact, the real domineering and qualitative leap of Luffy depends on Ka'er, Leopard Goro and Kaido, and two of these three are Luffy's opponents, it seems that only by fighting with powerful enemies can they really improve their own strength.
Katakuri - See the domineering teacher
The most buggy ability in Katakuri's body is "seeing and hearing domineering", his attainment of seeing and hearing domineering is very high, and even can achieve the degree of "predicting the future" for a short time, such an opponent is completely unseen by Luffy before. At that time, although Luffy mastered a certain degree of omniscience, he did not have the same insight and smell domineering spirit as Ka Er (foresaw the future), and was completely suppressed by Ka Er when he first fought with Him, but Luffy successfully awakened the same seeing and smelling domineering spirit as Ka Er in actual combat by relying on his excellent combat talent.
Many Haimi think that the battle of "Ka Er VS Luffy" is the key to really making Luffy's seeing and smelling domineering "advanced", if the opponent is not Ka Ii, I am afraid that Luffy's seeing and smelling domineering will not improve rapidly, from another point of view, Ka Ii is the real teacher of Luffy's "seeing and smelling domineering", of course, Luffy's talent is also an indispensable key element.
Goro The Leopard - Armed Color Domineering Teacher
And Luffy's "armed color domineering" is also inseparable from another teacher, that is, the leopard Goro of the Kingdom of Peace. Leopard Goro and Luffy met in Rabbit Prison, and although Leopard Goro is old and weak, he still has a super strong armed color domineering, which is called "Ryu Sakura" in the land of Peace. The armed color domineering spirit released by Leopard Goro is a high-level armed color domineering, which can have the effect of internal damage to the enemy, similar to "fighting cattle across the mountain".
And Luffy is qualified to clamor with Kaido, precisely because he followed The Leopard Goro to learn this high-level armed color domineering, for an opponent like Kaido who is "rough and thick-skinned", only from the inside of the destruction can have a substantial effect. If you don't count card two, Leopard Goro is Luffy's second legitimate domineering teacher.
Four Emperor Kaido - Overlord Color Domineering Teacher
Luffy's last "domineering teacher" is the four emperors kaido that we are familiar with. In the Battle of Ghost Island, Luffy and Kai fought most of the times, and Luffy slowly mastered the "other use of overlord color domineering" in one defeat after another, that is, "overlord color entanglement". In the collision between the strong, "hegemony" is an indispensable key ability, only a few people at sea can master the "hegemonic entanglement", and Luffy is relying on the actual combat experience with Kaido to successfully explore the "hegemonic entanglement".
Not only in a short period of time to master the "hegemonic entanglement", and even use the "hegemonic" and Kaido to fight into the "five-five open", which is why Haimi will ridicule Kaido as Luffy's "domineering teacher", if there is no Kaido, then Luffy will not master the "hegemonic entanglement" so quickly, it seems that Teacher Kai is well-intentioned, cultivating a new One Piece for us.
Of course, the above is just a joke, Luffy's domineering teachers are only Reilly and Leopard Goro, and the ability to master in actual combat is based on Luffy's outstanding combat talent.
