He possesses insane skills as a swordsman that can only be matched by few. When it comes to fighting, Zoro relies more on his brute strength more than anything. However, both in terms of power and speed, Zoro is far inferior to his captain, Straw Hat Luffy.
Sanji is arguably the fastest Straw Hat with or without the raid suit. Luffy comes extremely close.
Over long distances, Sanji may have better mobility and running pace. However, concerning combat speed, Zoro's fast reflexes and swift bursts of quickness are superior.
Zoro's Speed = . 1575/. 0000000131333333 = 11992385.8172m/s or . 04x Speed of Light (Sub-Relativistic) - So he's faster than Base Luffy from over 2 arcs ago, which seems about right.
In zoro vs luffy, luffy has greater will, greater haki and pretty much everything. Zoro loses easily.
Anti-Manner Kick Course. Anti-Manner Kick Course ( 反行儀 アンチマナー キックコース, Anchimanā Kikku Kōsu?): One of Sanji's strongest single kick attacks. He delivers a massive kick in which he lifts one of his legs a full 180 degrees in the air.
Sanji has extraordinary superhuman strength, resiliency, speed, and agility due to years of arduous training under Zeff since childhood, even before his latent genetic enhancements awoke, enabling him to use an array of handstands for a kick-based martial art that makes him immensely versatile in combat.
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. There, he learned Internal Destruction Ryuo and took Kaido on during the Onigashima Raid.
If we calculate this distance over time, Saitama speed comes up at 150 9236 miles per second, which is quite close to the speed of light. It's safe to assume that he merely jumped. with no charging up, which means he can be faster. In short, Saitama can travel at the speed of light.
Until Sanji becomes an ACoC Haki user, he unfortunately, has almost no chance of defeating Kaido. Luffy wasn't even able to meaningfully damage Kaido until unlocking his ACoC Haki, emphasis on meaningfully.
The narrative has shown that even when he faced Kaido, Kid did not waver and lose his will although he was tortured. However, Eustass Kid and Black Leg Sanji are more like equals in terms of power and skill. In a serious fight against each other, it is more likely that Sanji will emerge victorious.
Despite Sanji's incredible skills, he would lose a fight against Itachi.
Nami was one of the first characters to join the Straw Hat Pirates, and remains an extremely important character to the story. When it comes to strength, she's the weakest member of the crew, which is why she often relies on clever tricks and strategies in battle.
Monkey D. Luffy is the strongest Straw Hat Pirate member. From taking down Doflamingo to going toe-to-toe with Kaido, his exploits and achievements in the New World have been incredibly exciting.
2 Roanoa Zoro
This is because of his independent fighting style. He rarely relies on his crew mates for help, and while in a battle, he prefers to lay his trust in his own skills. Because he continues to train harder every day, Zoro is the second strongest in the Straw Hats.
Against Shanks, even if Luffy possesses weaker Haki, the Devil Fruit abilities of the Hito Hito no Mi, Model: Nika can make up for the deficit and see him emerge victorious. Currently, however, Shanks is likely stronger than Luffy, simply due to the fact that the plot demands that of him.
Quite easily one of the toughest battles that Zoro has been in is the one that he fought against Dracule Mihawk, the man who currently holds the title of the World's Strongest Swordsman.
As such, Luffy awakened the true abilities of the Nika fruit. With its powers, Luffy was able to topple even Kaido and if he could defeat the man who was the Strongest Creature Alive, he can certainly defeat Shanks as well.
