Name: Suigetsu Hōzuki
Rank: S-Class Rogue
Personality: Suigetsu appears to be indifferent, caring only for a few things around him. He spends a considerable amount of time mocking and/or being beaten by Karin, the only female member of Taka. Despite showing initial dislike towards his teammates, Suigetsu has grown fond of them, and was willing to risk his own life to protect them against the Eight-Tailed Beast.
Kisame claims that Suigetsu is a prodigy at the art of murder, as he has a habit of chopping off his victim's limbs before beheading them. Suigetsu, despite addressing him with the honorific term "senpai", wants to defeat him and take his sword, noting to Sasuke that he will one day serve him as "shark fin soup" (a reference to Kisame's shark-like appearance) after Sasuke suggested that he was not yet strong enough to defeat Kisame.
Suigetsu has a passion for collecting exotic swords: he made it his goal to collect all the swords from the Seven Ninja Swordsmen of the Mist. He took the Decapitating Carving Knife from Zabuza Momochi's grave, and joined Hebi only to take Kisame Hoshigaki's Samehada. However, his passion doesn't seem to be limited to the seven blades, as he also expressed interest in Darui's sword.
It appears that Suigetsu has a certain love for killing, but he refrains from satiating this desire due to his tacit fear of Sasuke. However, there are several occasions where he has killed people when he believed Sasuke wouldn't notice. Suigetsu has been shown to have thoughts such as "just this one" and "he'll forgive me". This shows the darker side to Suigetsu's personality, and a sign of things to come.
Suigetsu apparently likes to tease animals, as he was seen taunting the talking ninja cats from the abandoned Uchiha warehouse at one point, but lectured Sasuke on treating animals better after Sasuke used Manda to escape Deidara's ultimate self-explosion jutsu, resulting in Manda's death.
Appearance: Suigetsu has white hair with a light-blue tint to it, purple eyes, and wears a matching purple sleeveless shirt with gray pants. He wears a belt around his waist with water bottles attached to it, and another belt around his waist that holds his Decapitating Carving Knife.
Normally, Suigetsu looks lean and normal, but with his Hydration Technique, he can modify his body's shape and size, such as a muscular arm or merging with a larger body of water to become a tidal wave. If unconscious, Suigetsu is reduced to a jelly-like state. After the attack on the Eight-tailed beast, Suigetsu recovered in a large tank of water and resembles a fish-like being. Like all Seven Ninja Swordsmen of the Mist besides Raiga, Suigetsu has shark-like teeth.
Bio: Suigetsu was born in Kirigakure. Reputed to be the "Reincarnation of the Kijin", Suigetsu, together with his brother, Mangetsu, dreamt to inherit the title of Seven Ninja Swordsmen of the Mist. This acted as their motivation to finish cruel missions day by day. However, this dream was later shattered with the premature death of his brother, and Suigetsu changed his ambition to "collecting all of the swords". With the humiliation of being captured by Orochimaru, his ambition was put on hold.
Hunt for Itachi Arc
Immediately after Sasuke defeated Orochimaru, he went into one of Orochimaru's many experimentation labs and freed Suigetsu, who was sealed inside a holding tube in the form of water. After pointing out that he owed nothing to Sasuke for dealing with Orochimaru, Suigetsu agreed to join him. Once they left, Suigetsu had Sasuke take him to the Land of Waves to retrieve Zabuza's Decapitating Carving Knife from his grave. In the anime, the story of Suigetsu obtaining Zabuza's sword was expanded and lengthened out slightly for this episode in order to facilitate an earlier display of his abilities. The sword in question was taken from Zabuza's grave by a politician and crime boss named Tenzen Daikoku, who wanted to take the sword as a trophy, and for "revenge" after losing many men during Zabuza's attempted coup years before.
They then went to the base where Karin resided, where Suigetsu was instructed to free all the prisoners. Before releasing them, however, Suigetsu told them to spread the word that Sasuke killed Orochimaru, and would bring peace to the world. As Sasuke hadn't ordered him to say these things, his motives appear to be unclear.
Once Karin was persuaded to join, they headed to meet with Jūgo. They had to fight their way through an army of people branded with the Cursed Seals to reach him, and, under Sasuke's orders, were told not to kill any of them whilst subduing them. When they found Jūgo, who promptly attacked them, Suigetsu attempted to kill him. However, Sasuke intervened, and threatened to kill both of them if they didn't stop fighting. Jūgo eventually calmed down, and, with some persuasion on Sasuke's part, was recruited. Afterwards, Sasuke told them their mission and their new team's name; they would be known as "Hebi", and their mission was to find Itachi Uchiha.
Soon afterwards the team split up, searching for information about Itachi's whereabouts. This led Suigetsu to a bank where Akatsuki member Kakuzu's banker Genji was. Recognizing him as such, Suigetsu threatened him to talk. Seeing Deidara's large suicide bomb's explosion, Suigetsu was drawn to the site of Sasuke's battle with Deidara, where he had used a special seal to summon Manda and had used the snake to escape the explosion. It had, however, been a little too late, and Manda died, making Suigetsu tell Sasuke that he should treat animals a little better.
After they had rested and continued on their way, Sasuke found Itachi in an Akatsuki hideout. The clone of Itachi then guided Sasuke to an Uchiha hideout. On their way there, the group encountered Kisame Hoshigaki, who told them Sasuke must go alone. Leaving Hebi behind, Suigetsu challenged Kisame to a battle, who gladly accepted, while Sasuke finally made Itachi's death a reality. It was later revealed that Zetsu interfered in the fight, leaving both Suigetsu and Kisame alive.
Hunt for the Eight-Tails arc
Hebi, now renamed "Taka", began working with Akatsuki. They went to Kumogakure, and confronted Killer Bee, the host of the Eight-Tailed Giant Ox. Suigetsu attacked him first, but was quickly disarmed. He quickly engaged him again, but Killer Bee's electric attacks left Suigetsu outmatched. To be as useful to his team as he could, Suigetsu immobilized Killer Bee, allowing Sasuke a chance to attack them both. When Killer Bee turns into his beast and tried to use an Eight-Tailed Ox Menacing Ball on the team, Suigetsu used himself as a shield to block the attack. After that, he became a huge water form, with his sword at the core, resembling a cell, and fought single-handed against the unleashed beast. Although he lost and was left unconscious, he managed to gain the time that Karin needed to heal Sasuke, and letting him (Sasuke) use Amaterasu on the Eight-Tails. After the battle was over, Jūgo carried Suigetsu away.
While Taka recuperated, Suigetsu recovered in a tank of water. He yelled at Karin for leaving his sword behind, but was later seen to have recovered it.
Five Kage Summit arc
Once healed, Taka set out for Konoha. Along the way they are intercepted by Madara, who tells them of Konoha's destruction and their failure to capture the Eight-Tails. He convinces Sasuke to go to the Kage summit to kill Danzō, so Zetsu leads them to the land of Iron. Upon their arrival Suigetsu scouts the area, but finds there are too many samurai patrolling the area. Jūgo finds them an alternate route, where they are attacked by the samurai, having been exposed by Zetsu.
As Sasuke kills their attackers, Suigetsu points out that he is doing the very thing he forbids Suigetsu to do. The Fourth Raikage soon arrives to fight Sasuke and Suigetsu tries to help, but the Raikage breaks his Decapitating Carving Knife in half. He uses what remains of his blade to fight Darui. Darui infuses his own blade with electricity, allowing him to overpower Suigetsu and pin him to a wall.
When Sasuke destroys the room they are in, Suigetsu is freed. He retrieves his sword and regroups with Jūgo. They contemplate following Sasuke and the Raikage, but decide that would be too dangerous. Instead, Suigetsu suggests they dress up as samurai to gather information while avoiding drawing attention to themselves. They are quickly detected, and Jūgo stated that it wasn't the best plan.
