Background / History

Origin and Service to Dimon

Before gaining intelligence, the Vampire Fruit possessed a faint consciousness extending back thousands of years. Mammon vaguely remembered a former user becoming a Marine Admiral roughly three centuries earlier. Vice Admiral Pierce Field later identified that user in classified records as Admiral Black Bat 2 16.

Dimon recovered the fruit from the basement of Sleepy Town’s church and animated it after midnight. It grew into a humanoid more than two meters tall and immediately addressed him as “Master.” Dimon named him Mammon because the desire for eternal life represented greed 1 2.

Ordered to obtain blood from pirates, Mammon trapped the Warrior Pirates’ entire ship in darkness. He initially carried two prisoners back to Dimon, then killed the remaining crew and converted their blood into Longevity Wine. At Dimon’s request, he preserved the heads of three wanted pirates for their bounties 2 3.

Search for the Flame-Flame Fruit

Mammon accompanied Dimon to Farn Island, where he stopped Pierce Ed’s sword barehanded after the Marine mistook their captured vessel for a pirate threat. He subsequently gathered wanted posters and information about Portgas D. Ace, though his initial investigation found no trace of him 4 6.

During the journey to the East Blue, Mammon defended the ship against a Sea King. He later intimidated Krieg’s fleet into searching for Ace, remaining aboard Krieg’s ship while its crews investigated 8 9 10.

Using Krieg’s information, Mammon carried Dimon through a storm and helped locate Sixis Island. After Ain found the bird containing the Flame-Flame Fruit, Mammon killed it, recovered the fruit from its stomach, and shielded Dimon when its animation produced a surge of fire 11.

Marine Infiltration

Following the defeat of the Isaac Pirates, Dimon formally established the Seven Deadly Sins and assigned Mammon the title of Greed. Mammon’s mission was to join the Marines, obtain Punk Hazard’s coordinates or a contact number, and investigate whether a sentient Devil Fruit could learn Haki. He was also ordered to monitor Ed and kill him if he threatened to betray them 15.

At Marine Headquarters, Mammon posed as a bounty hunter and human Vampire Fruit user. Ed omitted Dimon from his account and presented Mammon as his rescuer. Impressed by the rarity and history of the fruit, Vice Admiral Field agreed to arrange a suitable identity. Mammon subsequently became a Headquarters captain 16 24.

While escorting Marine funds to a Sabaody auction, Mammon informed Dimon that the money was intended for a Devil Fruit purchase. He helped Dimon steal the Storyboard Fruit, using Darkness Realm to conceal their cooperation and knocking Ed unconscious. To preserve his cover, he then acted as though Dimon had defeated and imprisoned him 24 27 28.

Garp freed Mammon and Ed from the storyboard prison and accepted Mammon’s account without apparent suspicion. Garp later introduced him to Zephyr, believing that he could become a future Admiral. Mammon recognized the apprenticeship as both a chance to learn Haki and a legitimate route into Punk Hazard 32 36.

Punk Hazard Operation

Mammon awakened Haki under Zephyr and accompanied him to Punk Hazard as his disciple. Vegapunk requested a blood sample for artificial Mythical Zoan research, but Zephyr intervened before the request proceeded 37 39.

During the Seven Deadly Sins’ attack, Mammon protected Zephyr’s other students, Ain and Binz, from the fighting. He then intercepted Sigma’s Bolo Breath and fought the dragon in his awakened bat form, maintaining the appearance of a Marine defending the institute 40 42.

Inside Darkness Realm, Mammon privately instructed Sigma to injure him. Sigma’s lightning-charged wind blades severed one of his wings and sent him crashing near Zephyr and Vegapunk. Mammon continued the performance by preparing to fight despite his injuries, challenging the departing attackers, and finally collapsing 44.

Recovery and Marine Investigation

Mammon recuperated at GS General Hospital, where a doctor found that his wounds had nearly healed. While reviewing his actions for possible mistakes, he anticipated a formal investigation into the leak behind the Punk Hazard attack. He considered his original infiltration objective complete and believed he could fight his way out if exposed, though remaining undercover would allow him to continue learning Haki from Zephyr 55.

During his recovery, Mammon noticed that the battle with Sigma had strengthened his Haki and caused it to differ subtly from Zephyr’s. He did not understand the change and intended to test it after recovering. Ain then secretly delivered Dimon’s order to obtain a Devil Fruit Encyclopedia, and Mammon agreed to seek either a complete or incomplete copy after discharge 55.

After two more days of recuperation, Mammon left the hospital and returned to Marine Headquarters with Ain and Binz. Marine Criminal Investigation Bureau officers escorted them for routine questioning, explaining that Zephyr had already spoken on their behalf 65.

Vice Admiral Black Horse personally received Mammon, told him that an ancestor had eaten the Vampire Fruit, and proposed that he marry into the family through Black Horse’s niece. He supplied the young woman’s photograph and dismissed the investigation without questioning Mammon. Mammon subsequently overheard Zephyr pressing Sengoku to promote him 66.

Heavenly Tribute Assignment and Encyclopedia Retrieval

Sengoku assigned Mammon to escort the Heavenly Tribute and promised to promote him to major upon his return, allowing the advancement to follow normal procedure. Before meeting Sengoku, Mammon assured Zephyr that he had completely recovered, and Zephyr reminded him to continue his Haki training 66.

Before departing Marine Headquarters, Mammon openly requested a Devil Fruit Encyclopedia from his superiors. He obtained an incomplete copy recording more than three hundred fruits and read it aboard the escort warship while Ain transmitted its contents to Dimon 70.

Strong-Source Longevity Wine

While Mammon was in Alabasta, Dimon summoned him to test whether blood from a powerful individual would produce superior Longevity Wine. Mammon refined 1,000 cc of Hanafuda’s blood into a few dozen milliliters of concentrated essence. Dimon’s resulting Haki surge surprised them both, revealing that the source of the blood could greatly alter the wine’s potency 87.

Mammon explained that he had not known of this property because most of his previous victims had been ordinary people whose blood he consumed to stave off hunger. Dimon identified Impel Down’s powerful prisoners as potential sources of stronger blood and ordered Mammon to return to his Marine infiltration 87.

Later, aboard the second ship of a four-warship fleet heading toward Mary Geoise, Bethany approached Mammon in the mess hall. Although they already knew of one another, this was their first meeting. She assured him that the surrounding Marines could not detect her 93.

Bethany brought blood for Mammon to process, including a sample from Bullet. Mammon converted the final sample into Longevity Wine and impatiently ordered her to deliver it rather than delay Dimon with idle conversation 94.

Marine Counter-Surveillance Planning

The Marines later considered using Mammon’s Darkness Realm to counter Ain’s intangible surveillance. Dimon, who overheard their planning through Ain, acknowledged that Mammon’s ability could indeed block her observation. The proposal demonstrated that the Marines still regarded Mammon as a trusted asset, unaware that their intended countermeasure was another member of the Seven Deadly Sins 109.

Appearance

Mammon normally uses a youthful humanoid form more than two meters tall, with a formal appearance suited to his bodyguard role 1 6 36.

• Clothing: Wears a crisp black suit during his stay on Farn Island 6.
• Partial transformation: Can sprout black bat wings from his back and sharpen his fingernails into claws 4 8.
• Beast form: An enormous black bat capable of carrying people in flight 2 11.
• Awakened form: Surrounded by black mist resembling burning flames, arranged in a ring of dark flame clouds 42.

Personality

Mammon is reserved, dutiful, and intensely loyal to Dimon. His master’s orders take priority over everything else, a loyalty described as part of his underlying code. He usually responds with brief acknowledgments rather than displays of emotion 11 15.

He treats threats to the mission pragmatically. He kills the Warrior Pirates without concern for their identities and later recommends eliminating Ed to prevent exposure. When Dimon rejects that proposal, Mammon does not argue 2 3 27.

Despite his restrained manner, Mammon takes pride in being a Mythical Zoan. Samael’s dismissal of him as “just a bat” provokes his anger, while fighting Sigma gives him an opportunity to test his full strength against another animated fruit 12 42.

As an infiltrator, he habitually considers the worst-case outcome and rehearses explanations in advance. He is privately incredulous that Garp regards him as the Marines’ future, but readily exploits the opportunity to advance Dimon’s mission 28 36.

His caution extends to allied communications. He repeatedly warns Ain that speaking to him inside Marine facilities could expose their secret, recognizing that distant Observation Haki users might overhear a conversation even when no one is visibly nearby 55 66.

Mammon is initially unfamiliar with the importance of family connections and patronage in human organizations. Zephyr’s support during the investigation and Black Horse’s marriage proposal deepen his understanding of these relationships. He also develops genuine fondness for Zephyr, while accepting that their opposing allegiances limit their bond 65 66.

He has little patience for unnecessary socializing during missions. When Bethany attempts to prolong their conversation after he finishes processing blood, he tells her to leave rather than keep Dimon waiting 94.

Abilities & Skills

Vampire Physiology and Transformation

Mammon is the Vampire Fruit itself rather than a human who has eaten it. Animation gives him complete proficiency in its abilities from birth 2.

• Transforms between humanoid and giant black bat forms, or manifests wings and claws while remaining humanoid 2 4 8.
• Uses his wings for flight, cutting attacks, and shielding others 8 11 27.
• Stops Ed’s sword with one clawed hand without using Haki 4.
• Returns apparently uninjured after Sigma’s tail strike sends him crashing into a forest 42.
• Can grow stronger by drinking blood; he states that ordinary training does not improve his inherent strength 5.
• Possesses rapid recovery consistent with his Mythical Zoan nature. His Punk Hazard injuries nearly heal during hospitalization, and he later confirms that he has recovered completely without hidden injuries 55 66.
• Can safely eat ordinary human food, although he dislikes it and does so aboard Marine ships to avoid attracting attention 93.

Blood Draining and Longevity Wine

Mammon drains blood and life force from victims, then produces a substance he calls Blood of Immortality, which Dimon names Longevity Wine 3.

• Can reduce human victims to desiccated corpses within seconds 3.
• Replenishes his own energy through blood rather than ordinary human food 10.
• Produces wine that extends lifespan, preserves youth, and restores youthful vitality. Continued access can effectively sustain immortality, rather than making a single drink permanently sufficient 2 3.
• The wine greatly improves Dimon’s vitality and supports rapid physical strengthening through exercise; Dimon also observes apparent healing effects 3.
• Requires sufficient human blood to extend another person’s lifespan 2.
• Can refine blood collected separately in a container, without needing to drain its donor directly. In the Hanafuda experiment, he holds his hand over a bottle and condenses 1,000 cc of blood into a few dozen milliliters of wine 87.
• Wine made from a powerful individual’s blood can be markedly more potent than ordinary batches. Hanafuda’s blood produces a concentrated essence that causes Dimon’s Haki to erupt for seven or eight seconds 87.
• Processes blood delivered by Bethany, including a sample from Bullet, to support Dimon’s experiments with powerful donors 94.
• The wine has, at most, a very weak effect on animated devils such as Mammon and Bethany, whose humanlike appearances do not make them biologically human 94.

Darkness Realm

Darkness Realm produces an area of absolute darkness that Mammon can deploy and withdraw at will 2 27 44.

• Envelops an entire pirate ship or an area several hundred meters across 2 27.
• Deprives those inside of sight, causing confusion and preventing coordinated resistance 2.
• Remains active while Mammon leaves the enclosed ship to transport prisoners 2.
• Conceals cooperation with Dimon and Sigma from outside observers 27 44.
• Can block Ain’s surveillance. The Marines consider employing Mammon for this purpose, and Dimon confirms that the ability is a genuine counter to her observation 109.

Ultrasound and Sonic Attacks

Mammon uses ultrasonic waves both to survey his surroundings and to attack 2 9.

• Counts all 117 people aboard the Warrior Pirates’ ship 2.
• Locates Krieg inside his cabin through returning ultrasonic signals 9.
• Maps terrain and searches surrounding waters during the journey to Sixis Island 11.
• Projects a cone-shaped sonic attack that churns the sea, rocks Krieg’s ship, and causes weaker pirates to collapse coughing blood 9.
• Detects several immensely powerful auras with an ultrasonic scan upon first arriving at Marine Headquarters, before awakening Haki 16.

Haki

Mammon proves that an animated Devil Fruit can awaken Haki when Zephyr’s Armament Haki attack forces his own spirit and vitality to respond 37.

• Envelops his fist in Haki immediately after awakening it 37.
• Continues studying under Zephyr while maintaining his Marine identity 37 42.
• Releases Haki at full strength during his staged last stand at Punk Hazard 44.
• Experiences sudden Haki growth after fighting Sigma. During recovery, he produces a faint black coating on his fist and notices an unexplained difference between his Haki and an ordinary human’s 55.
• Uses Observation Haki to scan his surroundings at Marine Headquarters 66.

Undercover Operations

Mammon maintains a false identity as a human Mythical Zoan user, reporting intelligence to Dimon while serving as a Marine captain 16 24.

• Supplies information about Marine Devil Fruit purchases and Punk Hazard 24 39.
• Stages resistance, imprisonment, and battlefield defeat to disguise cooperation with the Seven Deadly Sins 27 28 44.
• Conceals most of his strength during Sengoku’s assessment, using only one-fifth of his power 42.
• Reviews his actions for inconsistencies while anticipating a Marine mole investigation 55.
• Passes the post-Punk Hazard investigation without being questioned by Black Horse, benefiting from his Marine reputation and Zephyr’s support 65 66.
• Obtains a Devil Fruit Encyclopedia through an ordinary request to his superiors rather than a theft, allowing Ain to transmit the contents to Dimon 70.
• Imitates Marine dining habits despite disliking human food 93.

Limits and Vulnerabilities

• Seawater and Seastone: Retains the standard vulnerabilities of a Devil Fruit user 2.
• Destructible body: Does not die in the human sense, but destruction of his humanoid body would require him to find another fruit to inhabit 2.
• Not invulnerable: Zephyr’s Haki injures his internal organs, and Sigma’s attack severs a wing 37 44.
• Relative strength: Sigma exceeds him in brute force, while Mammon holds the advantage in agility. Their fight does not establish a definitive overall ranking 44.
• Admiral potential: Garp and Zephyr regard him as a future Admiral candidate; he is not shown defeating an Admiral 36.
• Incomplete understanding: Complete proficiency in his fruit powers does not make him aware of every interaction they permit. He initially does not know that blood from powerful individuals produces more potent Longevity Wine, and he cannot explain the post-Sigma change in his Haki 55 87.
• Communication security: Secret conversations with Ain may be exposed if a powerful Observation Haki user deliberately monitors the area 55.

Relationships

• Dimon — Creator and master. Mammon serves as his bodyguard, blood supplier, and Marine infiltrator, placing his orders above all else 2 3 15. He later obtains a Devil Fruit Encyclopedia for him and refines powerful individuals’ blood for his Longevity Wine experiments 70 87 94.
• Pierce Ed — Entry point into the Marines and a potential security risk. Mammon protects him publicly while privately remaining prepared to kill him if necessary 15 16 27.
• Pierce Field — Marine sponsor who arranges Mammon’s identity and views his potential as an opportunity for the Pierce family 16.
• Garp — Unwitting benefactor who rescues Mammon, endorses his Admiral potential, and secures Zephyr’s instruction 32 36.
• Zephyr — Haki teacher and Marine mentor. His apprenticeship enables Mammon to enter Punk Hazard openly 36 37 39. Zephyr supports him during the subsequent investigation and pushes Sengoku to promote him. Mammon grows genuinely fond of his teacher but recognizes that their opposing loyalties prevent a closer bond 65 66.
• Samael — Fellow Seven Deadly Sins member and frequent source of irritation. Samael mocks Mammon’s humanoid form and Mythical Zoan status 12 44.
• Sigma — Fellow animated Mythical Zoan and combat opponent. Their genuine clash becomes a coordinated staged defeat to protect Mammon’s cover 42 44. The battle also triggers growth and an unexplained alteration in Mammon’s Haki 55.
• Ain, the animated Den Den Mushi Fruit — Fellow creation who supports communication between Mammon and Dimon 15 17 24. Mammon repeatedly cautions Ain against casual communication inside Marine facilities because of the risk of detection 55 66.
• Ain and Binz, Zephyr’s students — Marine companions whom Mammon protects during the Punk Hazard attack 39 40 42. They accompany him back to headquarters for the subsequent investigation 65.
• Vice Admiral Black Horse — Investigator who regards Mammon as a future Admiral and attempts to secure a family connection by proposing marriage to his niece. He gives Mammon her photograph and dismisses the investigation without questioning him 66.
• Sengoku — Fleet Admiral who assesses Mammon’s strength and later assigns him to escort the Heavenly Tribute, promising promotion to major after the mission 42 66. The Marines subsequently consider using Mammon’s Darkness Realm against Ain’s surveillance, unaware of his true allegiance 109.
• Bethany — Fellow Seven Deadly Sins member who first meets him aboard a Marine warship and delivers blood for conversion into Longevity Wine. She addresses him respectfully as Lord Greed, while he impatiently prioritizes completing Dimon’s task over conversation 93 94.
