Hatchan

Hatchan (はっちゃん, Hacchan, called "Hachi" by most characters) is an octopus fish-man. Hatchan is not very bright but a skilled swordsman, using rokutōryū ("six sword style"). He fights with Zoro during the Arlong arc. Despite Zoro suffering a fever and severe blood loss from his unhealed wounds (which he got earlier fighting Mihawk), Hatchan is still defeated by him. Later in the manga (in a title page arc that was never animated), Hatchan goes on many adventures, which end up in him opening a floating takoyaki restaurant.

Hatchan's name is quite strange. In the Japanese language, chan is a diminutive suffix, added to the end of someone's name, giving it the meaning of "cute" or "little". However, Hatchan insists that his name is Hatchan and that Hachi is just a nickname. When questioned on this, Oda replied that the chan is the same as the last name of "Chan" common in Chinese, rather than the suffix -chan.

Early Life
8 years ago, Hatchan was a member of the Arlong Pirates. After Arlong killed Bellemere, Hatchan went in her house and found a map. Nami charged at him, telling him that it's her map which she drew it herself and demanded it back. Arlong, whom read the map, was amazed at her talent and ordered Hatchan to bring her with them. Hatchan grabbed Nami by the neck and went to where Arlong Park would now stand. Compared to his present appearance, the only difference in his past appearance was that Hatchan wore a diamond-checkered outfit as opposed to the striped outfit he wears today.

Service under Arlong
Hatchan first appeared escorting Captain Nezumi in an Octopus Pot. He was Arlong's First Mate. Before he escorted Nezumi back to his ship, he made a comment on how Nezumi's mouse face made him laugh, which Arlong scolded him for. Hatchan then went on to escort Nezumi out of Arlong Park.

Later, he was seen again after Arlong went to Cocoyashi, he was alone cooking a giant boar for Mohmoo. He called out for him with his mouth as a horn, however Mohmoo did not come. However, Zoro, who was in Arlong Park, noted the call, and found Hatchan. However, unknown to Hatchan, Zoro had recently slashed up his buddies. Hatchan, thinking Zoro was a guest, escorted him to Cocoyashi to find Arlong.

Hatchan went back to Arlong Park and was met by an angry Arlong, whom had returned, and was angrily asked where he had been. Hatchan saw many of his buddies slashed up, prompting him to angrily swear revenge. However, when Kuroobi asked him if he had seen someone like Zoro, Hatchan started to describe the guest's appearance, finally realizing the guest's true identity, much to his comrades chagrin. He then started to explain himself that he believed Zoro to be one of Arlongs guests (like Nezumi).

Later, an Marine Banch 77 under Commodore Purin Purin came to rescue the Goza citizens, but wrongfully decided to attack Arlong Park. Chew, Kuroobi and Hatchan formed a teamwork to handle them. Hatchan's job was to move a cliff under the Marine ship, which passed over it with tremendous speed (thanks to Kuroobi), causing a maelstorm, sinking the ship.

Decisive Battle in Arlong Park
After Nami's money had been taken by Nezumi, Monkey D. Luffy broke down the gates of Arlong Park, together with Usopp, Sanji and Roronoa Zoro (whom Hatchan immediatly recognized). Once again, he called forth Mohmoo, only to find it with a giant bump on it's head, and a severe fear of Luffy and Sanji (whom had previously beaten it). After it had been defeated (along with the rest of the crew, save for Arlong, Hatchan, Chew and Kuroobi), the fishmen prepared to fight the Straw-Hats.

Hatchan started off the fight by firing a jet spray of ink at Luffy (whom had stuck himself in order to defeat the lesser fishmen), before slamming a piece of debris at him, only for Sanji to destroy it with a single kick. As he attempted another debris throw, Zoro taunts him into a fight, leaving Luffy, Zoro and Usopp to the others.

After Luffy was thrown into the ocean by Arlong, Zoro charged at Hatchan, cutting his hair after the fishman ducked from the incoming blow. After an unsuccessful attempt at catching Zoro's sword, Hatchan clung himself to the roof of Arlong Park, intending to stall Zoro, making it difficult to rescue Luffy. However, Zoro soon collapses due to the wound he recieved earlier from Mihawk, prompting Hatchan to rapidly punch the pillar he stuck himself to, in an attempt to crush Zoro beneath it. However, Zoro responds by throwing Hatchan beneath the crumbling structure, before collapsing once again.

Enraged, Hatchan exploded from the rubble, now wielding six swords in his Six-Sword Style, in order to vanquish Zoro for humiliating him. However, Zoro was undaunted and asked Johnny and Yosaku to lend him their swords, in order to use his Santoryu.

The weight of One's Swords
Johnny and Yosaku soon throw their swords towards Zoro but because of his increasing fever, he is unable to move to catch them. At this moment, Hatchan attempts to cut Zoro into pieces with his Six-Sword Style, but Zoro reverses it with his Tou Rou Nagashi, repelling all of Hatchan's swords, whilst cutting the fishman's abdomen.

Enraged, Hatchan tries to break it down to Zoro simply: His six swords automatically outrank Zoro's three swords. However, Zoro responds by saying that his swords are heavier than Hatchan's. Not understanding what Zoro meant with what he said, Hatchan performs a pot-stance attack on Zoro, who blocks it, until Hatchan releases the swords from their stance, allowing him to land a devastating headbutt to Zoro's chest, re-opening the wound from Mihawk.

While Zoro is in the air, Hatchan starts spinning his blades, in an attempt to grind Zoro into pieces once he comes in contact with them. However, Zoro manages to masterfully evade every single blade, whilst cutting the fishman's hands. Enraged, the fishman attempts the pot-stance again, but its repelled by Zoro's Oni Giri, which destroys all of his swords. Smiling, Zoro asks Hatchan if he knew what he meant when he said that his swords were heavier than Hatchan's.

In one last attempt to defeat Zoro, Hatchan tries to punch Zoro into submission, but this was stopped by Zoro's Tatsumaki, which sent the fishman flying. Defeated, Hatchan wonders how three swords could beat six swords, before slamming into the ground.

Final Efforts
However, after Kuroobi's and Chew's defeats at Sanji's and Usopp's hands respectively, as Luffy was receiving recovery, Hatchan arose from his place of defeat. However, Hatchan's intentions was not to defeat Zoro, but instead killing Luffy and those who were on the ocean bed.

At the bottom of the sea, Hatchan encountered Sanji and Nojiko. In a last-ditch effort to stop them, Hatchan tried to punch Sanji with his multiple arms, but Nojiko swam in the way of the punches. Luckily, before he could harm any of them, his wounds re-opened, just like Zoro predicted, allowing Sanji to release Luffy.

Hatchan's Sea-Floor Stroll
Shortly after the defeat of Arlong, Hatchan was brougth on a Marine prison ship. He escaped and decided to go home. He initially does some simple good deeds, including removing a hook from a panda shark, giving food (which was given in gratitude by the pandashark he rescued earlier) to a stranded islander and finding a ring for a goldfish bride. Gaining a trident from the goldfish kingdom, he used it to stab a monster attempting to eat a sea boar. After saving the boar, it unexpectedly spits out a small mermaid named Camie and a starfish named Pappug, whom Hatchan befriends with little problem. But he betrays Camie when the Macro Fishman Pirates give him a map to help him find the artifacts needed to create his most prized talent: takoyaki. Unfortunately, the map merely directs Hatchan to the octo-creature Mash, whom he defeats but helps him in no way towards making his takoyaki.

Feeling betrayed by the Macro Pirates and soon encountering a saddened Pappug still wanting Camie back, Hatchan attacks their ship and reunites starfish and mermaid. But when he returns to the creature, he discovered that the creature helped him after all: under his shell (which opens like a lid in a similar fashion to Brook's skull-head) was a massive jar of the best takoyaki-cooking sauce.

Taking the creature, the sauce and a ton of treasure stolen from the Macro Pirates, Hatchan continued his journey until he arrived at a town of catfish, ruined and desolate and particularly hungry. Hoping to help them out, Hatchan sells off all his treasure for cooking equipment and a cart, using it to create enough takoyaki not just to help the catfish but to propose to his girlfriend, Octopako. His girlfriend turned him down, but the catfish were grateful and in love with the takoyaki created by the octopus man. While originally dejected by his initial failure, encouragement from Camie, his original dreams (where it was shown that he, along with Chew and Kuroobi planned to open a Takoyaki-selling business) and a new ship built in gratitude by the catfish let Hatchan decide to stay true to himself. In the end, he decides to go through and open up a new floating takoyaki stand Takoyaki 8, with the mermaid and starfish occasionally helping on support.

Shabondy
Hatchan is currently held as a hostage by the Macro gang and Flying Fish Riders. The Straw Hat crew is currently trying to rescue him, without realizing who it is they're trying to rescue, though Zoro, Sanji and Nami have made references on how he seems to be familiar. Upon reaching him, Hatchan attempted to conceal his identity by coating himself with his ink. Unfortunately, his voice was recognized by Zoro along with his silhoutte and even Nami found him suspicious. Sanji tricked the Fish-man into admitting his identity by asking him about Arlong. When the Straw Hats found out that he's the Hatchi that served Arlong, they changed their mind about rescuing him, but Nami decides to rescue Hatchi because he's harmless and they already made a promise with Camie.

Trivia

 * In Hatchan's Sea-Floor Stroll, it's revealed that Hatchan, along with Kuroobi, planned to open a takoyaki store when they were younger, proving that they have been friends before meeting Jimbei and joining his crew.


 * His dumbness could be a ironic reference on the high intelligence of the octopus: As seen when Hatchan is stunned in a flinching manner thinking the Usopp Rubberband attack was coming straight for him when Usopp was far away.


 * Another irony is the fact that he sells takoyaki, a food made of octopus. However, to prevent it from being cannibalism, Hatchan creates his takoyaki from other tentacled creatures, such as the sea monster Mash.


 * Macro noted that Hatchan's species, an octopus fishman is a rare species that can sell for a good price.
