Luffy will be the Pirate King, but he isn’t the only one with such potential in One Piece.
The Pirate King is the most prestigious title that any pirate can hold in One Piece. As the name implies, the Pirate King is the person who conquers all the seas and goes on to find the One Piece. The Pirate King is also the strongest in the world, though it is not necessary for the strongest to be called the Pirate King, given that one would have to circumnavigate the entire globe and find the One Piece to claim the title.
So far, only the captain of the Roger Pirates, Gol D. Roger, has held this incredible title. However, there are many individuals in One Piece who are deserving of being called the Pirate King as well. In the future of One Piece, fans will likely see someone emerge and take this title.
Eustass Kid
Pirate Crew: Kid Pirates
Devil Fruit: Jiki Jiki no Mi
Haki: All Three
Eustass Kid is an individual with the makings of a king. This isn’t much of a surprise to the fans, given that he has access to the power of Conqueror’s Haki. Kid is a very determined individual, and he has gone head-to-head against multiple Yonko during his career as a pirate.
Kid even played a massive role in defeating Big Mom, and that just goes to show his strength. However, he was recently crushed by Shanks, which means Kid still has some more training to do before he ascends to the next level. Despite being destroyed, one cannot count Kid out completely and he will likely continue his quest for the One Piece soon enough.
Trafalgar Law
Pirate Crew: Heart Pirates
Devil Fruit: Ope Ope no Mi
Haki: Armament, Observation
Trafalgar Law is another member of the Worst Generation, and certainly one of the strongest in the new era. After the events of Wano, he was given a 3 billion Berry bounty, and fans know for a fact that he is one of the strongest of the new era.
Law aims to get to the Final Island and claim the One Piece as well, even though he isn’t all that interested in the treasure, and his main concern is surrounding the Checkered Fate of the D.
