Although they may seem convoluted and complex at times, the structures of the various groups ofOne Pieceare fairly important to the world-building of the story. Between the command structure of the Navy, the finer details of the bounty system, and the many different groups that are peppered throughout the series, the structure ofOne Pieceseems to be too intricate for its good at times. Still, these elements are one of the parts that make the series so unique, setting it apart from any other anime released so far.
As many fans have already read,One Piecehas introduced yet another group of characters during the Final Saga of the series. This group, the Holy Knights, for many, feels like one of the biggest “endgame” forces thatOne Piecehas to offer. Although little was known about the World Government forces before,the Elbaf Arc ofOne Piecehas introduced a small detail that may share a lot of information about the inner structure of this group.

Chapter 1137 Of One Piece Reveals A New Kind Of Holy Knight
Shamrock Is The Commander Of The Holy Knights
The Holy Knights, or God’s Knights, inOne Piece, are the incredibly powerful characters that defend the World Government’s Holy Land of Marie Geoise. This group is tasked with protecting any World Noble that requires assistance, though at the same time, they can punish any noble they deem to be conducting themselves improperly. In many ways, this group is the final line of defense forOne Piece’sWorld Government and Nobles, acting as the strongest force at their disposal.

This group, although few details have been shared inOne Piece’sFinal Saga so far, consists of nine individuals at the very least. So far, only three characters have been confirmed to be a part of the group, the Supreme Commander Figerland Garling, Figerland Shamrock, and Gunko. Outside of this, the silhouettes of two more, unconfirmed figures have been shown off. However, by the end of Egghead Island, Figerland Garling has left his post as a Holy Knight andjoined the ranks ofOne Piece’sFive Elders.
Shamrock’s Position As Commander Reveals The Potential Chain Of Command Of The Group
The Holy Knights May Still Be Under Figerland Or A New Individual
In Chapter 1137 ofOne Piece, although the character has been shown off a few times in the preceding chapters, fans are finally formally introduced to Figerland Shamrock, Shanks’s mysterious doppelgänger. In this chapter, he is introduced as the Commander of the Holy Knights, a World Noble, and the son oftheOne PieceElder, Figerland Garling. Although this is the first reveal of the character, his position as Commander of the Holy Knights reveals some information about the inner workings of the group.
Firstly, this title of Commander reveals that either a new leader to replace Figerland Garling hasn’t been chosen yet, or the Elder still commands the forces of the Holy Knights. However, it could also mean that another character, that hasn’t been revealed so far, was made the new Supreme Commander of the Holy Knights. If this is true, then it raises many questions about the inner workings and politics ofOne Piece’sHoly Knightsas a whole.

There May Be Many Commanders Of One Piece’s Holy Knights
The Chain Of Command For This Group Could Be Longer Than Expected
Assuming there is only one Supreme Commander of the group, there is no way to tell how many Commanders the group may have. For example, while Shamrock may be a Commander of the group, another Commander may have been promoted over him. Though, at the same time, the previous Commander may have been promoted to the position of Supreme Commander whileShanks’s mysterious twin, Shamrock, was next in line for the Commander position. However, being the son of the former Supreme Commander, it seems unlikely that Shamrock wouldn’t be promoted over another character.
I’d hoped we could have settled this much more cleanly… - Shamrock
Until more information is revealed, however, fans are only left with these assumptions about the inner workings ofOne Piece’sHoly Knights, which includesthe Arrow-Arrow Fruit user Gunko. So far, a hierarchy of a Supreme Commander and a Commander is known. However, the small detail that Shamrock was only a Commander and not a Supreme Commander reveals the potential for a massive chain of command within this newOne Piecegroup.
