Hatchan

Hatchan, nicknamed "Hachi" (ハチ Hachi?), is an octopus fish-man who was an officer of the Arlong Pirates before their defeat, and a member of the Sun Pirates before that.

After the rest of the Arlong Pirates were arrested, Hatchan was the sole escapee, and underwent many adventures which ended in him opening a floating takoyaki restaurant and meeting up again with the Straw Hat Pirates.He was one of the major antagonists of the Arlong Park Arc. He also is the central character from Hatchan's Sea-Floor Stroll Cover Page Serial. Later, along with Camie, he is one of the main supporting characters for both the Sabaody Archipelago and Fish-Man Island Arcs as an ally of the Straw Hat Pirates.

Abilities and Powers

Hatchan can shoot streams of ink from his mouth like a true octopus in order to blind the enemy, and to assist his combat style by striking down the enemies while they cannot see. He also covered himself with it in the failed attempt to conceal his identity from the Straw Hat Pirates.

Physical Abilities
Hatchan has massive amount of strength, being one of the top members of the Sun Pirates and an officer of the Arlong Pirates. He easily defeated the Macro Pirates, who were fish-men themselves, single-handedly and sending them flying with a three armed punches. His strength allows him to easily wield six extremely heavy cutlasses, each weighing over 300 kg while maintaining speed. He was the only one of the entire Arlong Pirates to escape the Marines' prison convoy. He is also aware of the existence of Haki, but admits that he knows very little about it.

As a fish-man, Hatchan is an expert swimmer. Even as a child, he managed to save Rayleigh from drowning at sea during a shipwreck. Even after being seriously injured during timeskip, that it required him to use crutches, Hatchan still displayed great swimming prowess, being able to swim a considerably far distance before being struck down by the barrage of arrows that Decken sent at him after he marked Hatchan as his target. Even when brutally pierced by Decken's arrows in a heavily injured state, Hatchan still managed to swim back to Fish-Man Island to warn the Straw Hats of Hody's invasion.

Hatchan seems to have incredible endurance as he was able to survive getting slashed by Zoro's three swords and Sanji's kick. Both are great deeds especially since Hatchan also got up sooner than any of the other fish-man after getting beaten by Zoro. However, during both times, he was at the advantage as Zoro had been badly injured by Mihawk, and Sanji's kick was under water, reducing his power and speed. Even when seriously injured, he was the only fish-man from the Arlong Pirates to escape. Even after being assaulted by Decken, having been pierced by several arrows and losing a lot of blood, he still survived and was able to swim to the surface and later warn Sanji and Chopper of Hody and Decken's plans.

Swordsmanship
Hatchan is a highly skilled swordsman and a master of the Rokutoryu. As an Octopus Fish-Man with six arms, Hatchan can simultaneously wield six swords with great dexterity and versatility. He has stated that he is the number two swordsman in all of Fish-Man Island. Hyouzou stated that if Arlong did not have a "tight-wallet", he would not have settled for Hatchan. If he was still the second strongest swordsman on Fish-Man Island during the Fish-Man Island Arc, then he would become the new strongest swordsman on Fish-Man Island when the Energy Steroids made Hyouzou's body old and weak. Even Zoro had trouble when he fought him and barely won (though he was greatly limited by the wound he sustained from Mihawk). Using Rokutoryu, Hatchan could cut down members of the Flying Fish Riders while they are flying in mid air. For two years, Hatchan could fend off the Marines to protect the Thousand Sunny with Duval, the other members of the Rosy Life Riders, and Bartholomew Kuma.

In the anime, he was able to create a tornado by flailing his swords wildly, similar to Zoro's Tatsumaki.

Weapons
Each of his swords is a cutlass that weighs over 300 kg (661.387 lbs), totaling to over 2 tons worth of metal, which is far more than a normal human's limit.

During his adventures, Hatchan was given a golden trident by the Goldfish Princess for returning her ring. He showed proficiency in its usage by defeating a sea monster that was chasing a Seaboar.

Culinary Expertise
Hatchan is a highly skilled chef, having once roasted an entire pig to feed the Sea Cow Momoo. He is particularly masterful in cooking takoyaki, with his takoyaki being deeply appreciated by the Straw Hat Pirates including Sanji, a master chef. Hatchan cooks takoyaki with great speed and dexterity. With his six arms, he could make large numbers of takoyaki to feed the Straw Hats, particularly Luffy, who has an enormous appetite.
