History

Amazon Lily campaign

After Boa Hancock defeated Rear Admiral Strawberry while avenging Fisher Tiger, Marine Headquarters issued bounties and arrest warrants for the entire Kuja Pirates crew. Intelligence later identified Amazon Lily as the crew's base after tracking its movements through the Calm Belt. 10

Fleet Admiral Sengoku decided that recruiting Hancock as a Warlord of the Sea was preferable to a prolonged conflict. He dispatched Vice Admiral Aokiji and a Marine fleet toward Amazon Lily, initially granting Strawberry three days to secure Hancock's acceptance. 10

Aokiji later led nine warships into the Calm Belt and froze hundreds of miles of sea to immobilize the Kuja ship and establish a battlefield favorable to the Marines. Norse melted the frozen battlefield and destroyed Marine warships, forcing the operation into failure. 14 16

Escalation against Norse

Marine Headquarters initially issued Norse an inaccurate wanted poster with a bounty of only 100 Berries and an image that did not resemble him, causing other pirates to underestimate him. 29

Following Norse's victory over Aokiji, his bounty rose to 1 billion Berries. Headquarters then sent Zephyr to recruit him directly into the Marines at admiral rank, but Norse refused and severed part of Zephyr's arm in their ensuing fight; the bounty subsequently rose to 1.2 billion Berries. 23 25 44

After Kizaru and Akainu were defeated or severely injured during another attempt to confront Norse, Marine Headquarters and the World Government classified him as an extremely dangerous great pirate and raised his bounty to 1.5 billion Berries. Headquarters suppressed details of these defeats from public reports. 41 44 76

East Blue hostage operation

Marine Headquarters later mobilized approximately one hundred warships, Sea-Prism Stone weapons, war machines, and Kizaru to capture Hancock. Its plan was to use her as leverage and summon Norse to a major battle where the Kuja Pirates could be eliminated. 87 88

The operation ended when Shanks intervened with the World Government's approval and secured Hancock's release in exchange for guaranteeing that Norse would not disrupt Marine order without cause. 89

Alabasta and New World negotiations

When Marine Headquarters learned that Pluton might exist in Alabasta and that Norse was present, Sengoku and Garp personally led a response force to the kingdom. 103

Sengoku later negotiated with Norse over half of the Poneglyph containing Pluton's blueprint. In exchange, Norse sought permission for the Kuja Pirates to enter the New World rather than clash with Marine forces. 109

At Norse and Hancock's wedding, Marine Headquarters sent senior representatives and presented Norse with a Devil Fruit. It later prepared an agreement allowing every member of Norse's crew to freely enter and leave the New World. 147 148

Later operations

After Norse's sea-restaurant gathering, Marine Headquarters resumed enforcement against pirates who had entered the New World without authorization. Kizaru pursued and killed the captain of the Hornet Pirates during one such operation. 150

When Devil Fruit users began becoming corrupted across the world, Marine Headquarters worked with the World Government to capture affected users and seal them with Sea-Prism Stone. The scale of the crisis exceeded its ability to contain every case. 171

Organization and Personnel

Senior officers

• Fleet Admiral Sengoku — Authorized the original bounty campaign against the Kuja Pirates, ordered Hancock's recruitment, and later led the Alabasta deployment and negotiations with Norse. 10 103 109
• Garp — One of Marine Headquarters' most prominent veterans; sought to restore Marine prestige by personally challenging Norse and later assisted with East Blue security during the Devil Fruit corruption crisis. 79 171 172
• Aokiji — Led the Amazon Lily operation and employed large-scale ice techniques to freeze the Calm Belt; later remained among the major officers pursuing physical growth. 10 14 136
• Zephyr — Marine instructor and admiral who attempted to recruit Norse; he lost part of an arm in battle and subsequently intensified his physical training. 23 24 136
• Kizaru — Admiral deployed against Norse on multiple occasions; later enforced New World entry restrictions and admitted to serving as a Revolutionary Army spy. 38 150 152
• Akainu / Red Fist — Admiral known for magma-based combat and extreme resolve; trained his body after fighting Norse and was later awakened through World Government-directed training. 88 106 172
• Rear Admiral Strawberry — Ambushed Fisher Tiger, fought Hancock, and acted as the initial vanguard in the attempt to recruit her. 10 12

Fleet assets and equipment

• Sea-Prism Stone–coated warships — Their hulls can pass through the Calm Belt because Sea Kings mistake the ships for part of the sea. 20
• Conventional naval armament — Marine fleets employ rifles, sabers, cannons, and Sea-Prism Stone nets against pirates and Devil Fruit users. 10 12 75
• Pacifistas — Deployed by Red Fist to destroy meteor fragments during the East Blue fleet battle. 88
• Transponder Snails — Used for emergency communication and reinforcement requests. 13 107
• Sea-Prism Stone seals — Used to confine corrupted Devil Fruit users captured during the worldwide crisis. 171

Policies and Methods

• Marine Headquarters offered Hancock a Warlord position and offered Norse immediate admiral status, demonstrating a willingness to recruit powerful pirates when direct suppression was costly. 10 23
• It concealed or minimized reports of major defeats by Norse, leaving the public to see rapidly rising bounties without the battles that justified them. 44 76
• Its fleets can conduct large-scale mobilizations, including the hundred-warship operation against the Kuja Pirates and the Alabasta deployment of dozens of warships with heavy artillery. 87 104
• It operates under World Government authority and relies on Celestial Dragon funding, a dependency that Sengoku privately regarded as limiting the Marines' ability to act according to their own ideals. 160
• Some Marines, including Garp and Sengoku, increasingly question the World Government's rule and have shown reluctance to place all hope for justice in its hands. 146 148

Relationships

• World Government — Marine Headquarters serves as its military force and follows orders from above, though internal disagreement over the Government's methods is implied. 160 171
• Kuja Pirates — Began as adversaries following Hancock's attack on Strawberry; repeated campaigns against the crew ended in severe Marine losses and later negotiations. 10 44 109
• Norse — A primary high-level threat whose defeats of Aokiji, Zephyr, Kizaru, and Akainu damaged Marine Headquarters' reputation and forced it into diplomacy. 44 109 148
• Boa Hancock — Initially targeted for arrest and later recruitment as a Warlord; Marine Headquarters eventually captured her to compel Norse into open conflict. 10 87 88
• Shichibukai — Marine Headquarters can summon Warlords such as Hawkeye Mihawk for major operations, though their cooperation may be limited. 88
