Shanks is one of the Four Sea Emperors and the captain of the Red Hair Pirates. Prior to the fall of Kaido and Big Mom, Shanks was the youngest of the Four Emperors, which is a testament to his power. Of all the Power Pirates, Shanks is the only one who doesn’t appear to have Devil Fruit, so he relies on his mastery of Haki to beat his opponents.
Near the end of the Wano Country Arc, Shanks was seen scaring one of the Navy Admirals with his Conqueror’s Haki shard. Although an Emperor is expected to be strong, this is a huge feat considering Shanks was nowhere near Greenbull’s location. Currently, Shanks is arguably the strongest character in A playmeaning there are only a handful of characters that can challenge him.
Akainu is the Fleet Admiral of the Marines. Endowed with the power of Magu Magu no Mi, he is the strongest Marine. His Devil Fruit allows him to create and control magma at will. Many consider his Devil Fruit to have the highest offensive power in the logia class.
Akainu is known for his tenacity and ruthlessness. During the Summit War, he was chasing pirates even after he managed to kill Portgas D. Ace. The only person who could overwhelm him was Whitebeard. Shanks and Akainu faced each other once, but that was a long time ago. Since then, Akainu has gained promotion and arguably become much stronger. A rematch between the two would certainly be interesting.
Monkey D. Luffy is the main protagonist of the series. Since beginning his journey to become the Pirate King, Luffy has undergone several trials that have made him stronger. The greatest test of Luffy’s strength came in the Land of Wa arc, where Luffy faced off against Kaido, who held the title of “World’s Strongest Creature”.
The fight against Kaido helped Luffy awaken his Devil Fruit and use it to the fullest. Besides that, Luffy also learned to coat his body with Conqueror’s Haki. This combination of his Devil Fruit and Haki allowed Luffy to damage Kaido’s indestructible body. Shanks knows that Luffy has come a long way since they last met, and if they were to fight, it would definitely be one of the best, if not the best fight in the series.
5/7 Black beard
Marshall D. Teach, also known as Blackbeard, is one of the Four Emperors of the Sea. Blackbeard rose to prominence after the Summit War. In a short time, he managed to become emperor and gain a ridiculously strong crew. Due to his special body, Blackbeard was able to consume a second Devil Fruit, which was the Gura Gura no Mi.
This Devil Fruit allows him to create earthquakes that can potentially destroy an entire island. To make matters worse, Blackbeard’s Yami Yami no Mi allows him to swallow anything into a pit of darkness, and he can even negate his opponents’ Devil Fruit powers. Blackbeard has also been shown using two types of Haki, but his proficiency remains to be seen. It’s clear that Shanks and Blackbeard have a history, so if they fight again, one of them will die.
Monkey D. Dragon is the leader of the Revolutionary Army. The goal of his organization is to overthrow the evil world government and free the world. Dragon has only appeared a handful of times in the series and he has yet to show his power. However, judging by the fact that he has complete authority over other powerful characters such as Sabo, Koala, Karasu, Morley and Belo BettyDragon must at least be more powerful than them.
For context, Sabo was easily able to fend off Admiral Fujitora in Dressrosa, implying that Dragon must be at least on par with an Emperor. The fight between Dragon and Shanks is very unlikely to happen, but if it does, fans can definitely expect a show.
Imu is the true leader of world government. They debuted in the Levely Arc, where the five elders could be seen bowing to them. Currently, there is very little information available about them, but that will change in the final saga.
As the head of the world government, Imu seems to have access to one of the ancient weapons that can decimate an entire island in seconds. Suffice it to say, Imu probably also has a Devil Fruit, and fans can expect it to be very powerful. The confrontation between Shanks and Imu may never happen, but the latter is one of the few characters who can challenge the Emperor.
2/7 Dracule Mihawk
Dracule Mihawk holds the title of “the strongest swordsman in the world”. He is currently a member of the Cross Guild, an organization that actively hunts down Marines. Before Mihawk was offered a spot within the Shichibukaihe was known as the “Navy Hunter”.
Mihawk was also a rival of Shanks and according to Whitebeard, the battles between the two were nothing short of legendary. After Shanks lost his arm, Mihawk stopped fighting him. If they decide to fight again in the future, it would put an end to the age-old debate over who is stronger between the two.
1/7 Trafalgar Law
Trafalgar Law is a member of the worst generation and the captain of the Heart Pirate. Law possesses the Ope Ope no Mi, a Paramecium-type demon, which is considered by many to be the “Ultimate Devil Fruit”. After eating his Devil Fruit at a very young age, Law was able to master all of the Devil Fruit’s abilities.
While battling Big Mom, Law demonstrated the power of his Devil Fruit awakening, and he used it to defeat her, though he needed Eustass Kid’s help. In the recent A play chapters, Law has been seen fighting Blackbeard on equal footing, which is a huge feat considering the caliber of his opponent.
