William functions as the crew's planner and field commander, repeatedly organizing divisions of labor, rescue operations, infiltrations, and retreats around Luffy's impulsive decisions. 21 137 409 548

Castle Army

William's Mythical Zoan ability contains a castle-like internal space, allowing the crew to conceal personnel, transport allies, shelter civilians, and deploy a force unexpectedly. Its strength is affected by the number of people stationed within it. 33 49

Known members or associated personnel of this force include:

• Nojiko — William's direct subordinate and an observant intelligence aide. 49 411
• Alvida — Former captain of the Alvida Pirates; Slip-Slip Fruit user. 49
• Mary — “White Rabbit” bounty hunter; marksman and direct combatant. 44 49
• Anne — “Black Cat” bounty hunter; one-sword-style combatant. 44 49
• Koala — Revolutionary Army Fish-Man Karate instructor. 49
• Baozi — Formerly Francis Bo, the “Demon King of the Seas”; William's companion. 156
• Ouji Lin — Swordsmith heir and wielder of the Seastone-equipped Forging Hammer. 156
• Fox Demon Tanji — Nine-Tailed Fox Mythical Zoan user with advanced Haki. 156 506
• Bartholomew Kuma — Assigned by Vegapunk to join the Castle Army after completing his protection of the Thousand Sunny. 316
• Perona, Monet, and Sugar — Devil Fruit users placed under William's protection or command following the Dressrosa conflict. 459

The Castle Army numbered approximately 1,500 soldiers during the Cake Island operation. 479

Public image and concealed strength

Most outside observers identify only a small public-facing group of Straw Hat pirates. Chopper was long misidentified as a pet, Brook's membership was initially unknown, and William deliberately concealed the Castle Army from the world. 318

This concealment led hostile forces to underestimate the crew's actual manpower and combat strength, even after the group became a major New World power. 333 479 499

History

Luffy began his voyage alone in the East Blue, soon encountering William, Nami, Zoro, and Usopp. Zoro became the first formally recruited combatant after Luffy returned his swords and affirmed his dream. 13 14 The crew became a true pirate organization after Usopp joined, Merry gifted them the Golden Merry, and Usopp created their straw-hat skull flag. 22

The crew expanded through the East Blue and Grand Line by gathering people whose goals, circumstances, or loyalties aligned with Luffy's. Their early victories over pirate crews and Baroque Works established them as an unusually capable rookie crew. By the time they reached Sabaody, four of their members qualified as Supernovas—an unprecedented number for one pirate crew. 15 72 193

Their assault on Enies Lobby to rescue Nico Robin transformed their reputation. The World Government classified them as an enemy force after they invaded one of its three major institutions and shot down its flag. 139 140 The incident placed every known member on wanted posters and made the crew internationally notorious. 157

Following the Summit War and a two-year separation, the crew returned with several hundred personnel, a protected Thousand Sunny, and far greater military capability. 333 Their victories and alliances later expanded them into the Straw Hat Alliance and Straw Hat Grand Fleet, enabling operations against the Big Mom Pirates and Beasts Pirates. 486 542 543
