Shiki He is one of the representative figures of the Gol D. Roger generation who is still active at sea. Shiki, known as the Golden Lion, was once a member of the Rocks Pirates and sailed with Rocks D. Xebec. He is known to be incredibly powerful, to the point where he was one of the leading pirates of the Rox era and beyond. Shiki assembled the largest fleet and even challenged Roger on several occasions. It was clear that he had a fairly high level of power.
Shiki's overall strength was at a level where he could challenge both Sengoku and Garp at the same time. In the battle, he destroyed half of Marineford despite the presence of these two powers. He was eventually trapped in Impel Down, but was able to escape from there by cutting off his own leg with the power of Fuwafuwanomi. Shiki was nearly impossible to stop in battle.

rocky
rocky One of the most powerful characters that exists in this world. one piece. As soon as he was born, it became incredibly clear that Loki was an absolute monster. However, his powers went to the next level 14 years ago when he consumed Ryu Ryu no Mi (Model: Nidhogg). In addition, Loki also wielded Ragnir, the legendary hammer wielded by Elbaf, the god of war. All of these powers combined put Loki beyond the level of most characters living in the world of One Piece. In fact, even modern-day emperors would have a hard time dealing with him, except perhaps Shanks.
Loki went to sea 14 years ago, and was there for 8 years before Shanks eventually brought him back to Elbaf. During these eight years, Loki could easily have earned the title of Emperor, especially since Shanks was not part of the Yonko at the time.

Dracula Mihawk
Dracula Mihawk One of the most powerful characters in . one piece world. Known as the world's strongest swordsman, he is also the former rival of the red-haired Shanks. Shanks and Mihawk have dueled several times over the years, each duel said to have echoed across the Grand Line. Their duels remain unstable to this day, meaning all of their battles have ultimately ended in draws. Considering that Mihawk is similar to Shanks in terms of strength, it is not surprising that he too was a Yonko level individual and continues to operate at this level today.
Mihawk could easily become emperor if he wanted to. But he doesn't like the extra attention that comes with it. Mihawk doesn't want to be chased by the Marines, nor does he want to be targeted by the younger generation of pirates. Therefore, he prefers a somewhat calm life, which can only be lived by staying away from noble titles such as emperor. No doubt Mihawk is very powerful and could easily become a Yonko if he was serious about becoming one.

trafalgar law
trafalgar law One of the most powerful individuals in the world. one piece From the next generation. He is a member of Luffy's generation and his powers are growing at an incredible rate. Recently in Wano, we saw how Law utilized his abilities in his battle with Big Mom. Big Mom's defeat was possible thanks to his efforts, and he achieved all of this without encountering any limitations as a pirate.

One Piece: All Yonko's Strongest Attacks, Rankings
Yonko are the most powerful pirates in the One Piece world and here are their most powerful attacks.
Law can still become stronger and utilize powers like the Conqueror's Haki, among others. Although he was recently defeated by Blackbeard, the fact that he has a bounty of 3 billion Berries, similar to Luffy's, means that Law also operates with a similar level of power. Law, now stronger after Wano, will not only be able to compete with the Emperors, but also retain his title. The only thing that stands in his way is his weak pirate crew. If the Heart Pirates level up their power by a large margin, Law would certainly become a worthy competitor to the Yonko living in the world of One Piece.

Eustace Kidd
Eustace Kidd An incredibly strong pirate from the New World. Like Luffy and Law, he has a 3 billion berry bounty that makes him extremely infamous. Kid fought Big Mom and Kaido in Wano. In her battle with Big Mom, she played a pivotal role in defeating and defeating her on Onigashima. Without Kid, it would definitely have been impossible to defeat the Emperor in the Wano Country Arc.
Kid definitely felt robbed when he found out that Luffy had become a Yonko instead of him. This is especially true since the bounties are similar and Kid completely believes that Luffy is equal, if not stronger. In the final story, Kid was completely dismembered by the red-haired Shanks with one swing of his blade, showing the difference between them. It's also important to remember that Shanks is the strongest of the Yonko at this point. Kidd still has to contend for the throne of Emperor. This is especially true as your pirate crew becomes stronger.

For decades he ruled the island until he was eventually ousted by none other than Blackbeard following the Rocky Port incident.
During those decades, Wang Zhi could easily have become emperor. In fact, it is quite possible that Wang Ji, who ruled Pirate Island, one of the most dangerous and key places in the pirate world before Shanks, served as the fourth Emperor of the Sea. His current whereabouts are unknown to fans, but if he wasn't a Yonko, he would definitely have been stripped of the title due to his immense influence.
