Hatchan

“You got an interesting face, Mouse-Umi. Your name sure fits you.” (page 15 — accidentally-insulting his captain’s bribed Marine customer)

• Cheerful big-mouth — accidentally insults Nezumi (“Mouse-Umi”); Arlong has to chastise: “Hold your tongue, Hachi! Captain Nezumi is a valued customer!!!” Arlong-Pirates background mooks confirm: “Sorry, captain!! That one’s got a big mouth!!” (page 16).
• Transports passengers in his octopus-pot — Hatchan-as-cargo-ferry register.
• Mid-tier comic-relief villain — distinct from Arlong’s hard-edged racism.
• Officer-discipline register install (Ch. 75): Hatchan calls for restraint of the over-eager mooks before engaging the Marines (page 11 — ‘WAIT, BROTHERS.’). The big-mouth-cheerful register from Ch. 69 is paired with an officer-discipline register — Hatchan is not just comic-relief; he is a functional first mate who can call for tactical restraint.
• Joins Kuroobi and Choo as the three-officer engagement-team against the Marine ship (Ch. 75 page 12). The chapter is the first on-page three-officer-coordinated-deployment of the Arlong Pirates.

Arc-by-arc updates

Fish-Man Island — the dissenting voice in the District (flashback, Ch. 644)

• Shown in the Fish-Man District telling stories the radicalized crowd finds “sick” (“I don’t like your stories, Hachi!”); described as “a strange one, never shrank back in disgust” — a lone fish-man unpoisoned by the inherited hatred.

Fish-Man Island — the reason he was attacked (Ch. 629)

• Bandaged and present with the Straw Hat group; finally admits (under Sanji’s questioning) that the New Fish-Man Pirates beat him because he sided with the Straw Hats / is friendly with humans (p. 11). Laments “I can’t go see them! As long as the legacy of Arlong lives on here…” — too afraid to visit his fish-man friends.

Fish-Man Island — the Sun Pirates split (flashback, Ch. 624) — shown (flashback)

• Shown leaving with Arlong’s faction when the Sun Pirates fracture — Arlong: “Come on, Hachi!” / Hachi: “We’re going back to the way we used to be, Captain Jimbei.” (p. 16). On-page bridge from his Sun-Pirates origin to the Arlong Pirates.

Fish-Man Island — young Hachi in the Sun-Pirates flashback (Ch. 620)

• Confirmed on-page as a member of Fisher Tiger’s Sun Pirates (named by Jinbei, p. 16) — alongside Jinbei and Arlong. Appears as the younger “Hachi” aboard the Sun Pirates’ ship 15 years ago (p. 17 — “Why all the noise?” / “Shut up, Hachi”), paying off his forehead sun-brand.

Fish-Man Island — wounded at the Sea Forest (Ch. 619)

• Found gravely wounded; lowered to Franky to be caught at the Forest of the Sea (p. 12). His injuries are attributed to Hody Jones (p. 16).
• Came to Fish-Man Island “hoping to find” Luffy; did not realize Ryugu Palace was in danger (p. 16). Reacts to seeing Shirahoshi (“My mermaid princess!”).

Fish-Man Island — referenced (Ch. 618) — not shown

• Off-page but referenced: Hatchan (Hachi) was recently wounded and gave Sanji a blood transfusion; Chopper blames Sanji’s new petrification symptom on it (“So who did that to you anyway, Hatchi?!”, p. 4). A Fish-Man plaza soldier (Sheller) recognizes him as Arlong’s old crewmate (p. 5).

Fish-Man Island — wounded at Coral Hill (Ch. 617)

• Found gravely wounded on Coral Hill’s coast amid the mermaid-kidnapping accusations; Sanji tries to steady him (“Get ahold of yourself, Hachi!”) and Chopper treats him (“Are you hurt?! Who did this to you?!”, pp. 14-15). He keeps telling the crew only to “leave the island.”

Fish-Man Island (Ch. 615) — on-page; marked by Vander Decken; washes up at Coral Hill

• On Fish-Man Island as the events open; a former Arlong Pirates officer whom Hody Jones and Hyouzou once “looked up to,” now scorned as a “coward” for befriending humans (pp. 8-9).
• Tries to stop Hody’s rally, is marked and stabbed by Vander Decken IX, flees through the water as the knives pursue, and washes up gravely wounded at Coral Hill — where he warns the Straw Hats of the coming invasion and to leave (pp. 10-12, 5-6).
• Recalls Luffy “still called me his friend… he saved my life” and longs to see him (p. 9).

Fish-Man Island — referenced (recovering in the Fish-Man District) (Ch. 608) — referenced, not shown

• Referenced: Camie says Hatchin is recovering in the Fish-Man District — he was “really badly injured last year” while protecting the Sunny (i.e., at Sabaody) (p. 13).

Fish-Man Island descent — referenced (Ch. 603) — referenced, not shown

• Referenced: Hachi was to guide the Sunny down to the seafloor but “suffered severe injuries at Sabaody and had to go back to Fish-Man Island to get treatment” — “the same as Duval” (p. 13).

Referenced in Amazon Lily (Ch. 521) — the sun-brand reveal — not shown

• The sun mark on Hachi’s forehead is revealed to be the disguised Celestial Dragon slave brand, overwritten with a sun by the Pirates of the Sun — meaning Hachi was once a slave of the World Nobles and a member of Fisher Tiger’s crew (“he must’ve belonged to the Pirates of the Sun at some point,” pp. 9, 16-17). Luffy mentions him by name to Hancock. See The Sun Mark Erases The Slave Brand As A Symbol Of Liberation.

Sabaody Archipelago (Ch. 514) — referenced

• At Shakky’s bar, reassures Camie that the Straw Hats are strong and will be all right (p. 4).

Sabaody Archipelago — resting at Shakky’s bar (Ch. 507) — referenced

Sabaody Archipelago — wounded, at Shakky’s bar (Ch. 506)

• Badly wounded (from the auction-house Celestial-Dragon incident); carried to Shakky’s Rip-off Bar to rest (pp. 7-8).
• Backstory: saved Rayleigh’s life 20 years ago when Rayleigh was lost at sea; close friends until Hachi joined the Sun Pirates (p. 9). Knew Rayleigh’s true identity but never told the crew.

Sabaody Archipelago — Rayleigh’s scolding (Ch. 504)

• Revealed to personally know Rayleigh, who scolds him: “I’ve always told you not to walk around on this island. You’re not going to die, are you, Hachi?” (p. 13) — deepening the established prior relationship between Hachi and the Dark King.

Sabaody Archipelago — wounded, and the Rayleigh reunion (Ch. 503)

• Gravely wounded protecting Camie; Nami tends his injuries (pp. 6, 13).
• Recognizes the auctioned old man on sight — “R-Rayleigh…” — and is recognized in turn: “Hachi! That’s you, isn’t it?! Long time no see!!” — establishing a pre-existing acquaintance with Rayleigh (pp. 16-17).

Sabaody Archipelago — outed and shot at the auction house (Ch. 502)

• Tries to stop Luffy from freeing Camie, knowing the slave collar will detonate and the World Nobles are present (pp. 12-13).
• Publicly exposed as a fish-man; the crowd reacts with violent racism (pp. 12-13 — “Why is he that color?! Why does he have so many arms?!” / “A fish-man!! How disgusting!!”). See Fish-Men.
• Shot by Saint Charlos’s father, then repeatedly by Charlos himself (pp. 14-17), yet apologizes to Luffy and to Nami: “I was a pirate once!! …I just wanted to help you. I wanted to make it up to Nami, even just a little.” — an on-page redemption beat closing his post-Arlong arc.

Sabaody Archipelago — confronting the slavers (Ch. 501)

• Reaches Grove 1 first with Pappag; openly calls the auction “slavery” and “human trafficking,” and is told a “lawless pirate has no right to preach morals” (pp. 12-13).
• Learns the captors have legal ownership of Camie and that the rescue is blocked by Celestial Dragons inside (pp. 12-14).

Sabaody Archipelago — Octo-Hachi searches for Camie (Ch. 500)

• As “Octo-Hachi,” hides his fish-man identity and scours the human shops for the kidnapped Camie with Luffy and Pappag (pp. 7-9).
• Tearfully blames himself for Camie’s capture; Luffy declares “You three are our friends now!” (pp. 9, 12). See Fish-Men.

Sabaody Archipelago — Sabaody Park & mobilizing for Camie (Ch. 499)

• Brings Camie, Pappag and the park group to Sabaody Park (pp. 4-9). When Camie is kidnapped by Peterman’s Hound Pets, moves to call in the Flying Fish Riders for help — “there are pros for this sort of thing” (p. 19). Pays off his post-Arlong “roving non-villain” cover-story arc.

Sabaody Archipelago — reunion with Shakky (Ch. 498)

• Leads the crew to Grove 13 and reunites with the bar-owner Shakuyaku (“Shakky”) after ~10 years (pp. 5-6). Confirmed to have quit piracy — Shakky: “I see. You quit being a pirate. That’s good” (p. 7); now runs a takoyaki/octopus-fritter shop (Camie works there).
• First sustained main-story (non-cover) appearance since the Arlong arc carries straight into the Shakky reunion.

Sabaody Archipelago — the walking tour & the slave-collar warning (Ch. 497)

• Guides Luffy’s group through Sabaody Archipelago in disguise, repeatedly warning them not to stand out, not to oppose the World Nobles, and to pass as Sabaodian humans — “Camie’s not a mermaid, and I’m not a fish-man” (pp. 4-5).
• Knows the archipelago intimately: explains bubble-bike rentals (cuts off Luffy buying one), the resin climate, hotels, and the human-trafficking danger; a local recognizes him as “from around here” (p. 7). See Ship Coating.
• Refuses to let the crew intervene when the runaway slave Devil Dias is killed — “Don’t get involved!! …a pirate who was caught and sold by human traffickers” (pp. 13-15). See Slave Collars Explode If The Chain Is Broken.

Sabaody Archipelago — fritters, the geography lecture & the World-Nobles warning (Ch. 496)

• Feeds the whole crew his prized octopus fritters aboard the Sunny (“I needed six more arms…”, p. 8); Pappag praises him: “Good work, Hatchin!”
• Reveals the seafloor route to Fish-Man Island and warns of sea monsters / Neptunians that eat ships (p. 11); promises to take the crew to a trusted coating specialist (p. 18-19) — seeds Hachis Trusted Coating Specialist Setup.
• Extracts the crew’s promise never to defy the World Nobles — the chapter’s gravest beat: even if one kills someone in front of you, pretend you saw nothing (p. 19); seeds Hachis Warning Dont Defy The World Nobles. See World Nobles.

Sabaody Archipelago — cues Camie’s rescue (Ch. 495)

• Travelling with the Straw Hats; cues Camie’s rescue by reminding Duval’s crew that mermaids out-swim fish-men — “Hey, cowboy, you forgot about someone” (p. 7).

Sabaody Archipelago — referenced during the Duval fight (Ch. 494) — not shown

• Referenced, not shown. Now travelling under the Straw Hats’ protection (freed @0492-0493), “Hach” remains the rescue/escort objective driving the crew’s fight with the Flying Fish Riders; Camie voices the goal — “I just wanted to rescue Hach and get out of here!” (p. 8).

Sabaody Archipelago — Flying Fish Riders rout (Ch. 493)

• Travelling with the Straw Hats, Hatchan is caged and used “like a punching bag” by the fish-man Macro Gang while tied up; Zoro cuts the cage free and Hatchan thanks “Roronoa” (pp. 8, 10). He routs the Macro Gang with the six-sword “Octopus Fritter Frenzy” (p. 9) and brags about a “new sword technique, goldfish-style” (p. 8). Acts as a Straw Hat ally against the Flying Fish Riders.

Sabaody Archipelago — shown in person; the Arlong-first-mate reveal (Ch. 492)

• First on-page in-person reappearance since the Arlong arc (cover-story-only since the Ch. 0093 Arlong Park defeat). Appears as “Hatchin,” an octopus-fritter shop owner traveling with the mermaid Camie and the starfish Pappag (p. 8 caption: “Octopus Fritter Shop Owner”).
• Held captive in a cage by the Macro Gang / Flying Fish Riders at the Flying Fish Riders’ Hideout; warns Camie to flee rather than be caught herself (pp. 9-12, 15).
• His identity as the Arlong Pirates’ former first mate is exposed on-page when Luffy asks “How’s Arlong doing?”; Nami recognizes his voice and silhouette (“I knew it was you!!”) and Robin confirms it (pp. 12-13: “That octopus was the first mate in the gang”). He alone escaped when the Navy arrested the rest of the gang. See Hatchan Octopus Fish-Man First Mate.
• Luffy/Nami initially refuse to rescue an old enemy but do so anyway after Camie is recaptured. Freed, Hatchan declares himself in Luffy’s debt (p. 18: “Whoa! Straw Hat Luffy! You’re awesome!! I’m in your debt!!”).

Sabaody Archipelago — “Hatchin” identity bridge (Ch. 491) — voice only, not shown

• Revealed (via Camie / Pappag) as “Hatchin,” owner of the octopus-fritters shop where Camie works — “He makes the best-tasting snacks in the world!!” (p. 10). This bridges the cover-serial Hachi into the main Sabaody plot.
• Captured: the Macro Gang (Macro Pirates) beat him by teaming with the Flying Fish Riders and answer his transponder snail to taunt Camie; weak, Hatchin warns her “do not come here” and that he’ll handle it himself (pp. 6-8).
• The Straw Hats begin to recognize “Hatchin” as the Arlong-Pirate octopus fish-man they fought (“Reminds me of that idiot fish-man we met that one time… Octopus? Hachi??”) — Zoro/Sanji note they “won’t save him… not that it could really be him… right?” (pp. 14-15). Continuity callback to Arlong Pirates / Arlong Park.

Cover story — Hachi’s Walk on the Seafloor, Vol. 34 (Ch. 220) — “Octopako is Drawn by the Aroma of the Sauce”

• Hachi’s Walk on the Seafloor, Vol. 34: “Octopako is Drawn by the Aroma of the Sauce” (Ch. 220 p. 1 cover) — Octopako (Octopako) follows a sauce-aroma smell-trail toward Hatchan. Notable because the Ch. 0220 main-story title — “A Walk on the Seafloor” — deliberately mirrors the cover-serial title, with the A-plot literally set on the seafloor (Masira’s salvage dive). Cross-link Hachi Walk On The Seafloor Cover Story Vol 34 Octopako Sauce Aroma.

Hatchan in his iconic striped leg-warmers stands at the GOLDFISH EMPIRE arched undersea kingdom; crowned goldfish-creatures with shocked/awed expressions approach him in awe; one offers a golden trident as a gratitude-gift. All six tentacle-arms raised in surprise. Sea-floor anemones and small bottom-feeders scatter around. First (or at-minimum eighth-installment — Vol. 8 implies prior 7) on-page Hatchan cover-story serial appearance since the Ch. 0083 Arlong-Park-arc defeat. The Goldfish Empire setting pre-loads forward-canon undersea-civilization world-building (the broader Fishman/Merman undersea-kingdom narrative that later anchors Sabaody and Fishman Island arcs). The golden trident gift — given by a grateful kingdom — pre-loads Hatchan’s forward-canon Sabaody-arc redemption-arc (his Saul-defection / takoyaki-stand civilian-reformed identity).

Hachi (six-armed octopus-man, polka-dotted shirt) emerges from the surf walking toward a small palm-tree island where a tiny lone figure (a child fisher) sits. The Receives a Ring in Gratitude subtitle implies a reward-token from a rescue-incident. Hatchan’s post-Arlong-Park redemption-arc is operationally tracked across the Alabasta-arc cover-stories. Pre-loads forward-canon Hatchan-as-Takoyaki-vendor / friend-of-the-Strawhats arc (Sabaody Archipelago). Cross-link Hachi Walk On Seafloor Cover Story Vol 6 Receives Ring (new).

Arlong Park (first sustained Luffy-combat; first named techniques) (Ch. 93)

• First on-page named techniques deployed:
  • Shark Tooth Drill (pages 13-14, BAM!!!) — head-rotation-as-drill-tip attack on the chart-room remnants. Etymology: Hatchan’s head-spin converts his own teeth into a rotating drill-tip; species-trait-as-named-attack register (cf. Arlong’s Finger Net Ch. 92).
  • Battle Axe (pages 14-15, WOOOO → CHONK!!!) — multi-leg overhead stomp. Name-mirror with Luffy’s Ch. 65 Gum-Gum Battle Axe — Battle Axe attack-name spans captain-and-officer registers across crews.
• First sustained combat-on-panel in the Luffy fight (pages 13-15). The Ch. 86 fish-man-officer named-technique convention now extends to the Arlong-Pirates first-mate.
• Final on-page state: in the rubble of the collapsing Park (pages 15-16); fate held for Ch. 94.

Cover Story — Hachi’s Walk on the Seafloor, Vol. 5 — Hachi Encounters a Hungry Man (Ch. 187) — first on-page Hachi-encounters-a-human beat since the Arlong-arc defeat

• Ch. 187 — Vol. 5: Hachi Encounters a Hungry Man — Hachi (multi-arm fish-man with sun-marking on forehead) buried up to neck in beach-sand, smiling at a scruffy bearded muscular hungry man clutching a fish skeleton with longing-eyes. Three small black silhouette-creatures in foreground. First on-page Hachi-encounters-a-human beat since the Arlong-arc defeat. The seafloor-walk cover-story continues installing Hachi’s post-Arlong rehabilitation arc-grammar — the fish-man-formerly-villain is now a roving non-villain who encounters humans on land. Pre-loads forward-canon Hachi-helps-the-Strawhats arc-beats (Sabaody Archipelago Ch. 0489+). Cross-link Hachi Walk On The Seafloor Cover Story Vol 5 (new).

Cover Story — Hachi’s Walk on the Sea Floor, Vol. 4 — Hachi Receives a Thank-You Gift of Meat (Ch. 185) — merged from the former Characters/Hachi stub

Cover Story — Hachi’s Walk on the Sea Floor, Vol. 3 (Ch. 184) — LOAD-BEARING — first on-page post-Arlong Hatchan appearance; sea-floor survival-and-recovery confirmed

Sea-grass, jellyfish, anemones, small reef fish, distant shark in upper-right corner. Confirms Hatchan survived Ch. 93 Arlong Park collapse — the Walk on the Sea Floor serial-title (Vol. 3 means Vol. 1 and Vol. 2 are in chapters 182 and 183) canonizes him as a fish-man-island-adjacent undersea operator. Pre-loads the forward-canon Sabaody-arc Hachi-as-recurring-ally + takoyaki-stand-vendor reveal.

Cover-arc — Hachi’s Walk on the Sea Floor (Ch. 183) — Vol. 2 “Let’s Go Home”

Hachi the octopus fish-man walks the sea floor among small fish (one striped eel-like creature, an angelfish, several small fish, a coral-reef setting). First post-Arlong-arc on-cover Hachi appearance — establishes him alive after his Ch. 93 defeat at Arlong Park and undertaking a long return-journey. The subtitle canonizes his destination-objective: he is heading home to Fish-Man Island. Forward-canon: this cover-arc runs ~ several chapters and tells the Hachi-returns-home story; pre-loads his Sabaody-arc Takoyaki 8 stand-operator cameo.

Arlong Park — used as projectile by own captain (Ch. 91) — Thrown unconscious at Luffy; off-page treatment continues Ch. 88 captain-collateral register

Arlong Park — recovered; six-sword stance + Octopus-Fritter Frenzy first named (Ch. 89)

• Recovers from Ch. 88 captain-water-attack and re-engages Zoro.
• Slingshot-rubber-band fakeout (page 3 — Roing!! / Doom!!) — ‘Since you’re standing in front of me… you must want to die, Roronoa Zolo!!!’
• Six-sword stance revealed — six octopus-arms each wielding a sword. KLANG!! block against Zoro’s two-sword strike (page 4). Six-arm fighting style operationally locked in.
• Un-shatterable nose boast: ‘The reason I’m so proud of this nose is because it can’t be shattered!!! Even if you had real power… you’d be lucky just to scratch it!!!’ (page 4) — built-to-break per Pearl-template.
• Octopus-Fritter Frenzy named technique first launched (pages 5, 8) — six-octopus-arm pummel-flurry. Etymologically takoyaki.
• Comic-stupidity-as-character-tell continues (page 7 — ‘I MEANT OCTOPUS BOY. I WASN’T TALKING ABOUT ME!!’ — Hatchan misreads Sanji’s directive as personal).

Arlong Park (collateral damage of own captain) (Ch. 88) — Dropped by Arlong’s water-attack alongside Zoro; captain-overrides-officer-duel

• Dropped by Arlong’s water-pressure attack alongside Zoro, off-panel between Ch. 87 and Ch. 88 opening (page 6). Villager-witness: ‘It looked like he just splashed them with water… but then they coughed up blood and collapsed!!’ Arlong (own narration, page 8): ‘A handful of water is all it takes.’
• Collateral damage of his own captain’s clearing-the-board attack. The Ch. 84-87 Hatchan-vs-Zoro duel terminates not by either combatant winning but by Arlong intervening to drop both at once. Installs Arlong-doesn’t-spare-his-own-officers-clearing-the-board villain register.
• Forward-resonance: Hatchan’s Ch. 491+ Sun Pirates / Sabaody redemption arc’s Arlong-was-bad-and-I-knew-it reflection traces structurally to this chapter — the moment Arlong’s bad-faith toward his own crew is on-page.
• Status at chapter close: unconscious on pavement next to Zoro.

Arlong Park — Zoro-vs-Hatchan fight resolved off-page; KO’d in courtyard tableau (Ch. 87)

• Face-down KO’d on the destroyed courtyard pavement (page 3 — DOOM!!, HACHI…). The Ch. 84 Hatchan-vs-Zoro Six-Sword-Style-vs-Three-Sword-Style duel is resolved off-page (presumed Ch. 85-86).
• Status: defeated, on-pavement. Forward (Sabaody Ch. 491+): redemption-arc post-recovery.

Arlong Park (off-panel jeer during Genzo’s dive) (Ch. 86)

• Brief on-page (off-panel jeer): page 4 — “INTERESTING!! HE WANTS TO FIGHT ME, A FISH-MAN, UNDERWATER!!?” in dual-laughing-faces panel with Arlong (re: Genzo’s dive). Bystander to the Genzo-dive beat. The Ch. 84 Zoro-vs-Hatchan combat continues off-panel.

Arlong Park — defeated by Zoro (Ch. 85)

• Combat-vocabulary completes with four named attacks: Six-Sword Style doctrine-restate (page 3 — “can only be performed by someone with six arms and a charmingly flexible body”), Octopus-Pot Stance (page 9 — first stance-system name, タコ壺の構え / Takotsubo-no-Kamae), New Year’s Open Body Slam (pages 9-10), Waltz of Six Swords (pages 11-12 — chapter’s signature whirling-blades composition).
• 650-pound-blade boast (page 9 — “My swords weigh 650 pounds each!!! They’re much heavier than yours, puny human!!!”). Numeric weight-tier-canonization.
• Mid-leap self-defeat tonal-tell: “Oh no…” between launching and impact (page 10) — the Ch. 73-83 comic-failure register extends through combat-mode.
• Defeated in splayed-limbs blood-spurting composition (page 16). All six swords flying outward; inner monologue: “How could I lose to only three swords… I couldn’t have…” — loss-as-doctrinal-confusion, not malice. The redeemability pre-load extends through on-page defeat.
• Status at chapter close: defeated, airborne, blood-spurting — not confirmed-killed but combat-incapacitated. The Sun Pirates alumnus / Sabaody / Marineford forward-payoff implies survival.

Arlong Park (duel-pavement Ch. 84) (Ch. 84) — Hatchan-vs-Zoro duel locks; species-coded combat-vocabulary debuts (Ink Jet, Sword Catch, Octopus-Fritter Frenzy); Six-Sword Style named by Zoro; doctrine-line A human swordsman can never beat me!!!

• Faces off with Zoro on the Arlong Park pavement (Ch. 84 page 2 — WOOOO laugh-howl splash). The Ch. 78 six-sword-arm rampage forward-prediction lands at scheduled chapter. Sanji backs Zoro until the rescue-pivot diverts him into the Choo-fight.
• First named species-coded combat moves:
  • Ink Jet (page 4 — FLOOP): black ink spat from mouth/face. Hits Zoro’s hair-tip (page 5 — EEK!! MY HAIR!!!). Octopus-species combat-tell.
  • Sword Catch / Hachi’s Triple (page 7 — WMMBB FWASH): catches Zoro’s three-sword-strike on three head-mounted katanas. The 3
    sword-count geometry visualized at peak.
  • Six-arm whap-attack (page 8 — WHAP WHAP WHAP / UNH! UNH! UNH!): all six arms in rapid succession.
  • Gauntlet-stretch grab (page 12 — FWUMP): six-arm extended-reach grab from behind around Zoro’s head.
  • Octopus-Fritter Frenzy (page 13 — RMMBB / THOOM THOOM / KA-BLOOOSH!!): three-storey jumping-stomp finisher. Three-ton landing-mass on Zoro.
• Doctrine-line: ‘A HUMAN SWORDSMAN CAN NEVER BEAT ME!!!’ (Ch. 84 page 10). The Ch. 71 Lords of All Creation doctrine in species-instance-specialized form.
• Combat-discipline named as Six-Sword Style (Ch. 84 page 16) — Zoro: ‘NOW I’LL SHOW YOU THE THREE-SWORD STYLE’ / ‘SIX-SWORD STYLE SOUNDS SILLY. IS THAT FOR CHOPPING VEGETABLES!?’ First on-page utterance of Six-Sword Style (六刀流, Rokutōryū); contemptuous-rename grammar from Zoro (cf. Ch. 51 Buzzard Eye).
• Status at chapter close: standing on the pavement, dismissed Zoro’s vow-speech with ‘Shut up!! I’m not even trying!!!’ (page 9) and ‘Yeah, you talk a lot!!!’ (page 7); ready to engage Zoro’s now-restored three-sword-style with his own Six-Sword Style.

Arlong Park (first sustained combat sequence — Hachi Ink Jet named, clumsy-self-defeat combat-mode, Luffy bites him on the head) (Ch. 83)

• Flown across the sea on Momoo from the Grand Line (page 2 — MOOOO…!! …FROM THE GRAND LINE FLYING!!). Arlong launched Momoo (with Hatchan astride) across the sea as a delivery-method to drop Hatchan into the Arlong Park courtyard. The chapter opens with Hatchan as a flying-delivered combat-asset — Arlong’s single-fish-man-civic-scale-throwing feat in panoramic view.
• FIRST NAMED ATTACK: HACHI INK JET (page 4 — HACHI INK JET!!! / FLOOOSH!!): species-trait-as-combat-mechanic. TIME FOR… ZERO VISIBIL- ITY. — weaponizes the octopus ink-trait as a zero-visibility battlefield-modifier, not a direct-damage attack. The chapter establishes Hatchan’s combat-grammar as battlefield-control via species-trait. Forward-pattern: the Ch. 85-87 Hatchan-vs-Zoro six-sword-style sequence flows from this species-trait-as-combat-mechanic register (six arms = six swords).
• Self-blinds with his own ink-jet (page 5-6): OH NO! I LET GO OF HIM!! / AGH!! I CAN’T SEE ANYTHING!!! / WHY DIDN’T YOU JUMP OUT OF THE WAY!? — Hatchan’s zero-visibility attack disables him as much as the enemy. Then accidentally clubs Luffy out of the stone-trap (page 6 — INK JET HACHI… …ON THE ROCKS!!!! / WHAM!!! / KRAK!): blind club-swing smashes Luffy out of his stone-prison instead of finishing him off. The chapter installs Hatchan’s clumsy-self-defeat combat-mode — the Ch. 73-74 comic-failure-register extends fully into combat-mode.
• Recognizes Zoro as the courtyard-massacre perpetrator (page 9): ‘I ALMOST FORGOT ABOUT YOU!! RORONOA ZOLO!!’ + ‘AND YOU WIPED OUT MY COMRADES!!!’ (page 10). The Ch. 73-74 Hachi, you idiot!! That was him!! (Arlong re Zoro) reverses register — Hatchan now consciously recognizes Zoro as a tier-equal threat.
• Acknowledges Sanji’s strength as a human (page 8): ‘YOU’RE PRETTY STRONG, FOR A HUMAN… TO TAKE ME ON, HUMAN.’ — first on-page Hatchan-acknowledges-a-human-as-strong line. The Arlong-Pirates anti-human doctrine is, in Hatchan’s voice, further softened. Compounds the Hatchan Cant Recognize Humans Tell and Hatchan Octopus Fish-Man First Mate redeemability-pre-loads.
• Accidentally frees Luffy from the stone by clumsy tentacle-grip (page 11): KLUNK!! / SHOO!! / OH NO! I LET GO OF HIM!! — the enemy-accidentally-rescues-the-captain inversion via clumsy-combat-mode.
• Bitten on the head by Luffy (page 16 — CHOMP!!! / YOU BITER!!! / OW!!!). Hatchan retaliates by slamming Luffy down (BAM!! / HE’S FINISHED.) and dunking him in the pool (SPLASH!).
• Dives into the pool to finish Luffy underwater (page 17 final tier — TIME TO PLAY, EH? / WOOOOOO…). Octopus-arm-club raised; the chapter’s combat-cliffhanger.
• Status at chapter close: in the Arlong Park pool with Luffy, clubbing him underwater.

Arlong Park (combat-pivot — Momoo-summoner + Devil-Fruit-identifier of Luffy) (Ch. 82) — Re-summons Momoo via trumpet; identifies Luffy as DF-user; releases Momoo when summon fails

• Re-summons Momoo via trumpet (page 9, middle tier): ‘Arise, giant warrior!!!’ / ‘Do you boneheads think… you can push Lord Arlong around? I’ll turn you into chum!!!’ (TOOT TOOT-TOOO! TOOT! TOOOO!). The Ch. 73 Momoo-summoner-with-trumpet register is here re-deployed at the chapter-villain-stand pivot.
• Releases Momoo when summon fails (page 12): ‘I won’t stop you. Well, if you want to run away… Go ahead, Momoo.’ — Hatchan in calm-resigned register releases Momoo from the summoner-handler-contract. The chapter installs the summoner’s secondary register: release-when-the-creature-acts-on-its-own.
• Identifies Luffy as a Devil-Fruit user (page 15): ‘He has the power of the Devil Fruit!!!!’ — first on-page Arlong-Pirates identification of Luffy as a Devil-Fruit user. Hatchan’s recognition lands the crew’s awareness of Luffy’s power-class. Forward-payoff: Arlong’s water-as-trap-for-Luffy combat-tactic.
• Smug six-arms-flexed pose (page 9 top): ‘HAHAHAHA!! You’re just four people from an inferior species. What can you do!!?’ — the Ch. 73 cheerful-but-comic register is here paired with a anti-human-species pejorative. Hatchan-as-officer-side-of-Arlong-anti-human-doctrine register installs.

Arlong Park (present-day Arlong Park defense) (Ch. 81)

• At Arlong Park entrance (page 16) alongside Kuroobi and Choo, having bound/captured Yosaku and Johnny. Speaks (or one of the trio speaks): “We’re waiting for a certain crew that’s sure to show up here.” First present-day appearance after the Ch. 79 flashback-era debut.

Arlong Park — central-payload flashback (Ch. 79) — Borrowing-not-harming debut line; takes young Nami from village

• Named on-page by Arlong (“That’s a valuable skill. Bring her along, Hachi!!”, page 8). Grabs young Nami (WSH WSH SFX).
• First on-page line installs the least-cruel-officer register: “I won’t harm her. I’m just borrowing her.” (page 8) — deliberate moral-softening framing of an abduction. The character’s moral-distance-from-Arlong lands at his very first appearance in the Bell-mère flashback.
• Forward-resonance: Hachi’s eventual Sun Pirates alumnus reveal (Ch. 621+) and the post-arc takoyaki-stand redemption arc (Ch. 491+) are pre-loaded by this not-actually-cruel debut register.

Arlong Park — Bell-mère flashback (Ch. 78)

• First extended panel-coverage of six-sword reach (page 7): KANG / WAM / KRAK — Hatchan’s six sword-arms simultaneously demolish Bell-mère’s house interior. Establishing-shot for Hatchan as a combat threat (prior Ch. 69-70 appearances were as cheerful background officer).
• Reads the village register (page 12): identifies Bell-mère’s unmarried, childless paper-status; counts the three table-settings (“The table’s set for three!! There are three people living here!!”). His audit triggers the records-vs-lived-truth gap that becomes Bell-mère’s structural opening.
• Forward-payoff: the Ch. 84-87 Hatchan vs. Zoro duel where the six-vs-three-sword geometry is the duel’s central mechanic.

Arlong Park (comic-failure register installs) (Ch. 74) — I-towed-Zolo-to-Coco-Village confession; first-mate-as-comic-failure pattern installed

• The I-towed-Zolo-to-Coco-Village confession (page 7): Hatchan blithely admits he found a swordsman tied up in a boat in Arlong’s waters and — out of (apparent) helpfulness — towed him to Coco Village, not recognizing he was the Pirate Hunter who had just demolished Arlong Park. Arlong: “HACHI, YOU IDIOT!!! THAT WAS HIM!!!!” — the chapter’s central comic-set-piece.
• The good-natured-stupidity-as-the-villain-crew’s-vulnerability register installs — Hatchan is liked-by-readers-even-as-an-antagonist because his villainy is offset by his comic-failure mode. Pre-loads the long-burn Hatchan-villain-to-friend conversion arc across the series (Sabaody Ch. 491+, Fish-Man Island Ch. 612+, Marineford Ch. 605 death).
• Returns with Arlong from the off-property errand (page 6) — first chapter where Hatchan and Arlong are both on-page together actively engaged in plot. Hatchan in the entourage formation (background, looking goofy).

Arlong Park (front-entrance + Coco-Village ferry) (Ch. 73)

• Reappears at Arlong Park front entrance summoning Momoo with a trumpet (TOOT-TOOOOT). Page 2: “HEY, MOMOO!!! IT’S TIME TO EAT!!!” Hatchan-as-Momoo-handler role established.
• Cannot tell humans from fishmen (page 4): “Are you a fishman too?” / “But you look HUMAN!!” / “Of course!! I’m a cuddly octopus fishman!!” — Sanji has to deadpan-confirm he’s a fishman/guest. The Arlong-Pirates anti-human doctrine is not internalized by the first-mate in the same way as Arlong. Comic-relief framing; structurally important for the redeemability pre-load.
• Self-identifies as a cuddly octopus fishman (page 4, panel 5). Species-subtype self-naming canonizes the octopus-fishman taxon.
• Reveals Arlong’s whereabouts: “But Lord Arlong isn’t here right now. Arlong went to Coco Village to capture him [Usopp]!!” (page 5).
• Ferries Sanji into Coco Village (pages 5, 14) — Arlong’s first-mate as literal taxi for the enemy he can’t recognize. Sanji (sotto, page 14): “What a strange fishman.”
• Returns to find Arlong Park courtyard massacred (pages 15-17). “RAAAAAAAR!!! BROTHERS!!!” The chapter’s cliffhanger pivot.
• Sanji’s saw-nose epithet for Arlong (page 14): “That saw-nose is around here somewhere.” — Sanji’s villain-epithet register installs.

Hatchan recurs across the series — Sabaody arc (Ch. 491+) where he runs a takoyaki stand and is befriended by the Straw Hats, Fish-Man Island arc (Ch. 612+) where he’s a friendly elder, Marineford (Ch. 605) where his death is one of the series’ more affecting villain-to-friend conversions. The Ch. 69 install plants him as a villain whose redeemability is structurally pre-loaded by his cheerful temperament — even as an antagonist, he is liked by readers.
