The man known to be the strongest creature, Kaido is widely known to be the most powerful pirate right now, and the mightiest of all Yonko currently. He was an apprentice on Rocks D.
Shanks is the weakest Yonko.
1/10 Kaido
Known to be the strongest creature on land, air, and sea, Kaido is one of the Four Emperors, just like Big Mom, and has a bounty of 4,611,100,000 Berries on his head. He is known to be extremely difficult to hurt and throughout his life, only Kozuki Oden and his nine retainers have managed to hurt him.
King the Wildfire is the strongest of the three right-hand men of Yonko Kaido and he has a bounty of 1.390 billion berries. He belongs to the Lunarian race and has the power to combust into flames which is a power special to his race.
10) Jozu. Jozu is the former Commander of the Third Division of the Whitebeard Pirates. Most fans consider him the third strongest member of the crew, below Newgate and Marco, and possibly above Ace and Vista.
1) Edward Newgate - Whitebeard
He also developed a reputation as the world's strongest man. Even in poor health, the World Government was completely afraid of him. During the Paramount War, they spent all their resources against him.
Mihawk holds the title of "World's Greatest Swordsman" and, as such, it is beyond any doubt that his swordsmanship skills are superior to those of Shanks. This was, once again, brought up in One Piece 1058 where he was specifically compared to Shanks.
To counter Katakuri's Future Sight, comparable Observation Haki or much greater raw speed is needed. King possesses the required speed. However, to reach such quickness, he has to lower his otherwise unparalleled durability. King beats katakuri with high diff and it's not even a debate.
They absolutely possess the weapons to take them on and combat, however, defeating them is a different question altogether. The Admirals and the Yonko are certainly not equal in power and the former will always reign supreme as the strongest in the One Piece world, which Oda once again showed in the previous chapter.
Shanks has clashed against Kaido when the latter tried to reach Marineford. It is very likely that Shanks would be able to injure Kaido in this battle. Also, Shanks is one of the few people that Kaido believes is capable of fighting him.
Sengoku possesses a Mythical Zoan Devil Fruit that allows him to turn into a Buddha and attack using shockwaves. To date, he is the only Marine with the power to use all the three Haki types. Undoubtedly, with these abilities, he is capable of rivaling the Yonko.
Two years after the war, following the events of the Whole Cake Island Arc, the World Economy News Paper referred to Monkey D. Luffy as standing adjacent to the Four Emperors as the "Fifth Emperor" of the sea.
Following this, he was declared the 5th Emperor of the Sea, however, Luffy was never truly recognized by his peers. As such, his defeating Kaido and finally rising to the position of a Yonko is quite significant. This time, Luffy is globally recognized as one of the Yonko.
In terms of strength, Luffy is already at the level of the Yonko. While he may not have awakened his Devil Fruit, he's taken his Haki to the level of the Yonko, being able to use the advanced form of all three Haki types, which is something that no other Yonko can do at the moment.
Due to his age, Luffy is currently the youngest member among the Yonko. His current bounty is 3,000,000,000 berries.
6/10 Silvers Rayleigh — Fought & Injured Kizaru
He can use all three types of Haki, which puts him among the ranks of some of the biggest names in the series. Katakuri can put up a decent fight against the Dark King, but there's no way that he can win. Still, his strength in battle is formidable.
Katakuri awakened his powers, which means he can use the battlefield against Jack. He can set up several traps while delivering a strong flurry of punches. Katakuri has more than enough stamina to match Jack.
Katakuri can use all three types of Haki and he can actually use the Advanced versions of both Armament and Observational Haki. Biggest Feat: Charlotte Katakuri proved to be a strong opponent for Luffy, and it took Luffy using a new form of Gear Fourth to defeat him.
2/10 CAN BEAT: SHANKS
Shanks has no devil fruit and he specializes in Haki. Shanks has managed to clash against Kaido and then he stopped Akainu at Marineford. Garp holds a grudge against Shanks for turning Luffy into a pirate. Frankly, there is no Marine who can rival the strength of a Yonko and Garp is no exception.
Chapter 1058 has confirmed that Mihawk is not an Emperor because he simply has no interest in being one. Another problem that Shanks being stronger than Mihawk will lead to is Zoro and his goal.
They fought often and, by the looks of it, drew all of their battles which just goes to show that they were equally matched then. However, after Shanks lost his dominant arm in the East Blue, Mihawk stopped fighting him, likely thinking it wouldn't be fair to win in that manner. Consequently, their rivalry ended.
Having killed Whitebeard, stolen his Devil Fruit, and then acquired all his territories and his allies, he solidified himself as one of the strongest people on the seas and gained a bounty of 2.246 billion berries. The newest additions to the ranks of the Yonko are Monkey D. Luffy and Buggy.
Mihawk has fought many friendly duels with Shanks(one of the Yonko) and they both use swords as their weapon . Mihawk is a better swordsman than Shanks ,but Shanks has powerful haki and many other attacks . Though my point is that Mihawk has the potential to beat a Yonko.
The Yonko, at large, are still characters Zoro likely won't be able to defeat for quite some time. It's safe to say that Zoro is not yet at the level needed to reach his goal of defeating Mihawk and becoming the World's Greatest Swordsman.
