One Piece: Duel Monkey D Luffy vs Charlotte Katakuri

The One Piece manga fans get happy news after a leak from the One Piece chapter 894 summary is revealed. However, the battle of Monkey D Luffy and Katakuri turned out to be unfavorable for Luffy. Luffy seems overwhelmed to face a Katakuri that is not less powerful. However, Sanji's presence on the Thousand Sunny ships slightly lightened the weight of the Straw Hat crew.
As quoted from ComicBook, leaks the story says, Luffy continues to fight against Katakuri without any significant resistance. He did manage to attack the Sweet Commander, but Luffy was then trapped in a rope.
Katakuri then asks if Luffy is ready to surrender? But, fans certainly know that the Straw Hats boss is not going to give up so easily. If this summary is true, One Piece will provide a new technique for Gear Fourth for Luffy. The hero stood up again and activated the Fourth Gear: Snakeman, a movement no one had ever seen before.

So far, One Piece has shown Luffy able to open two variations of Gear Fourth shape. The first one was introduced when Luffy fought Doflamingo and the change of form made him immensely bouncy. Tankman is the second form that appears when Luffy fights against Charlotte Cracker and it fortifies the captain's body with Busoshoku Haki. Now, it is not known what Snakeman looks like. But, fans start guessing and some calling this form will involve Luffy getting Haki's fork tongue.

Of course, the discussion of duel Luffy vs. Katakuri this could be a spoiler for those who have not followed the latest developments in the manga. Especially for the faithful follow the anime. The battle in the anime version will be guaranteed to be more stunning, equipped with sound effects, colors, and visual effects. But you still have to wait a few more months to see it.
Some fans consider Luffy's duel against the first Sweet Commander he met, Cracker, less than satisfactory. The reason is the nature of Cracker who really likes to play safe in the fight. Instead of clashing directly, Cracker prefers to hide behind the biscuit armor. Then after the armor was destroyed, he took refuge behind a lot of biscuit soldiers.
Uniquely like this: Katakuri was once seen carrying a stick and shot people with jellybean bullets. But when serving Luffy, he seemed to deliberately imitate Luffy's technique.
According to the author, it looks like Katakuri uses Kenbunshoku Haki to read first what techniques Luffy will use. If so, then more and more proven Katakuri is a genius. Just by seeing what Luffy would do, he then imitated the captain's perfect straw technique. Not only that, Katakuri can use Luffy's skill more efficiently than Luffy himself.
How can it be? Actually, this is not a difficult thing for Katakuri. He tells Luffy that he is superior to the Straw Hat captain in everything, from speed and strength. For most criminals anyway it just boasted. But given Luffy ending chapter 879 with a severe injury, it's not just a big bullshit. Katakuri only convey the facts.

Luffy was badly wounded in the duel chapter 879. But he has not shown his ace, which is Gear 4. For the size of the manga shonen, you can imagine Luffy getting stronger by all the Gear 5 or Awakening Paramecia Gomu Gomu no Mi.

Luffy might be a fool for science. But his brain is sharp for what he likes, like a fight. Remember how he understood Soru from CP9, then developed Gear 2 to keep up? Before issuing a Hawk Gatling clone, Katakuri commented, "Here's more efficient." He then struck Luffy with Bushoshoku Haki's boxing barrage.
It is easy for Katakuri to exert Luffy's technique more efficiently than Luffy himself. The reason, he excelled from the Captain of the Straw Hat not only of strength but height and - of course - arm reach. He did not have to go forward like Luffy to hit the Straw Hat captain. Area punch was more focused.
But what if Katakuri, Luffy understands that the technique can be used more efficiently? His prime example was Hawk Gatling, which had just been used to crush him. Did he finally imitate the Katakuri way, so that all his punches were more focused and not wasted? Hawk Gatling is in the spotlight here because it's the technique that Katakuri returns as Luffy uses it. When they compete with Elephant Gun, Katakuri can create Elephant Gun that is even much larger than Luffy's. That is pure of its own strength.
Sure, Eiichiro Oda can make Luffy beat the Katakuri just by getting stronger thanks to Awakening or Gear 5. But it would be interesting if Luffy becomes strong just because he learns to be more efficient. It will show that Luffy is also strong from the start, but because his fist can knock out tough enemies in the Grand Line he has never sharpened his technique. Then he learned how to use his technique better than the Katakuri, so he could muster it without wasting too much energy and the direction of his attacks more precisely.
It would be interesting if this would happen later. Because that means Katakuri seemed to be Luffy's teacher, even though the Sweet Commander is clearly against Luffy just to kill him. What do you think about the Katakuri technique? Can he replicate Luffy's technique just because he's a genius, or is there another possibility? Should Luffy have to deploy Gear 5 or Awakening to win here?
