The Elbaf arc of One Piece introduces us to new characters and surprising plot twists. Chapter 1137 presents Shamrock Figarland, the heir of the Figarland family and son of Garling. He first appeared in Chapter 907, where he met the cunning Nefertari Cobra to discuss the name of a mysterious island.
However, it remains unknown whether Shamrock will become the twin brother of Shanks. Along with this, countless theories have emerged, particularly because the character does not bear the same scar on his face as Shanks does. He also sports a distinctive hairstyle, similar to his appearance in Chapter 1134 when he appears in Elbaf.

Shamrock also conceals his face with a distinctive hairstyle, similar to his appearance in Chapter 907. The only difference is that he can be seen, and his demeanor is entirely different from Shanks.
One Piece Chapter 1137 reveals Shamrock’s true intentions resembling those of Shanks.
Interestingly, unlike Shanks, who seeks to protect Elbaf, Shamrock’s objective is to infiltrate the central government’s control. He begins by targeting Loki, the prince of Elbaf, who is under threat from the Navy. As Loki refuses to negotiate, Shamrock reveals that there is a different plan at play. Chapter 1138 recently hinted at hidden secrets behind the complicated relationship between the two brothers, Shanks.
One Piece Chapter 1138 reveals Shamrock’s connection to Shanks.
During a conversation with Loki, Shamrock reveals that Shanks is actually his twin brother. He was separated from the Figarland family during the God Valley Incident. However, he once reached Mary Geoise only to find himself lost in the chaos of the island. Shamrock expresses his deep resentment towards the world government and feels a sense of loss because his brother is not part of his life. Shanks had previously discovered this connection in Chapter 1095, where he shed tears after Roger spoke to him about their family ties.

Roger serves as a father figure to Shanks. During the final voyage to Laugh Tale, Roger distanced himself from Buggy and Shanks, knowing that the journey ahead would be perilous for the young ones. At the age of ten, Shanks had only begun to realize that the Pirate King was planning to entrust him with a significant secret. However, Roger had previously shared another secret with Shanks before their parting: he had discovered a treasure hidden in the God Valley incident.
Roger took Shanks with him, but soon he realized the depth of the tragedy that would unfold at some point. Additionally, since Shanks is a renowned Pirate King, the Figarland family could not ignore him. The Celestial Dragons are the most privileged group of people, yet they too are drawn into the cycle of misery and villainy.
Despite the disdain of the public towards these privileged figures, the Navy’s power could pose a threat to anyone. Shanks had become accustomed to living freely among ordinary people, so a life of a Celestial Dragon was never something that interested him. Shanks might have approached his own family, but he resolutely decided that he would not allow himself to be dragged into the servitude of his own lineage.
