In One Piece, fans surely remember the iconic moment when Pirate King Gol D. Roger swung Ace’s sword to deliver the legendary Kamusari slash. As one of the 12 Supreme Grade Swords (Saijo O Wazamono), Ace is more than just a weapon, it symbolizes the peak power that once clashed with Whitebeard, Garp, and Rocks.
After Roger’s execution at Loguetown, the whereabouts of this sword remain a mystery. If Ace were to reappear one day, who would be worthy enough to carry on the legacy of this legendary blade?
Let’s take a look at the top 4 candidates in One Piece!
1. Portgas D. Ace

Symbolically, the clearest candidate is Roger’s son, Portgas D. Ace. His very name is inspired by the sword. However, the reality is quite ironic. Ace grew up resenting his father and chose a completely different path: relying on the Mera Mera no Mi Devil Fruit powers and his fists instead of swordsmanship.
Had Roger raised his son, we might have seen a truly cool “Ace wielding Ace” moment, but fate didn’t allow it.
2. Silvers Rayleigh

As Roger’s trusted right-hand man, the Dark King Rayleigh understands the true “soul” of Ace’s sword better than anyone. Both are master swordsmen, so Rayleigh certainly has the qualifications to inherit the captain’s weapon.
However, Rayleigh’s style differs. While Roger favored powerful, explosive slashes, Rayleigh fights with a more technical and swift approach. He might be better suited as the guardian of the legacy rather than a full successor to Roger’s style.
3. Yonko Shanks

When it comes to the perfect heir to Roger’s fighting style, Red-Haired Shanks stands out. From his stance to the Kamusari technique, Shanks is like a flawless replica of Roger at his peak. Even his sword Gryphon resembles Ace’s blade.
Yet the key point is that Shanks is already incredibly powerful and wields his own “destined sword.” He likely doesn’t need Ace’s sword to prove his status anymore.
4. Figarland Shamrock

This is a dark fan theory spreading among the community. As Shanks’ brother and Garling’s son, Shamrock holds a key position in the God’s Knights. What if the World Government secretly keeps Ace’s sword and plans to hand it to Shamrock?
Imagine Shamrock using Ace’s sword to replace Cerberus, or wielding both weapons simultaneously. This would shock Shanks and create an intense, dramatic showdown if the Figarland brothers were forced to face off with the Pirate King’s weapon.
