Suigetsu Hōzuki

is from Kirigakure's Hōzuki Clan. Heralded as the, Suigetsu dreams of gathering all the swords of the Seven Ninja Swordsmen of the Mist. This dream was cut short when he was captured by Orochimaru, but by joining forces with Sasuke Uchiha he finds an opportunity to resume its pursuit.

Background
Suigetsu was born in Kirigakure and was reputed alongside his brother, Mangetsu, to be the incarnation of the demon Zabuza Momochi. He and Mangetsu aspired to inherit the title of Seven Ninja Swordsmen of the Mist. This acted as their motivation to finish cruel missions day by day. While Mangetsu eventually became one of the seven, Suigetsu's motivation was shattered with the premature death of his brother, and he changed his ambition to "collecting all of the swords", in order to retrieve all seven original blades that have been passed down by the swordsmen, so that he could rebuild the group and become its leader.

With the humiliation of being captured and experimented on by Orochimaru and Kabuto Yakushi, his ambition was put on hold. Through these experiments, Kabuto at least, was able to replicate Suigetsu's unique secret ability to liquefy himself at will. At some point in the past, he had to fight with Jūgo.

In the anime, about two years after Sasuke joined Orochimaru, the young Uchiha delivered a vial for research on Suigetsu. Upon seeing the young Uchiha, Suigetsu asked Sasuke to free him, who simply said he had to prove his strength. As the medical-nin came in to begin their tests, Suigutesu noticed one of them was in a daze (unaware he was being controlled by Sasuke's Sharingan). The medical-nin then opened Suigetsu's chamber, allowing him to break free from the base. Soon afterwards, he was pursued by Sasuke and Karin. Using his various water abilities, he was able to fend off the duo. Taking Sasuke's sword and delighting in its design, he attacked Karin, only to be caught off guard and subdued by her chakra chain, allowing Karin to take him back to the base.

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 up by Karin. Despite showing initial dislike towards his team-mates, Suigetsu has grown fond of them, and was willing to risk his own life to protect them against the Eight-Tails, showing care for his team-mates.

Kisame Hoshigaki claims that Suigetsu is a prodigy in 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 honourific 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, showing it to be a sign of sarcasm rather than respect for Kisame.

As a prodigy at the art of murder, Suigetsu has a certain love for killing, but he refrains from doing so at Sasuke's request. 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 once" and "he'll forgive me". However, he was noticeably upset that Sasuke killed several samurai during the attack on the Kage Summit, pointing out how many times Sasuke had told him not to kill anyone, his anger may have had more to do with Sasuke being a hypocrite than the samurai's deaths. He was described to have a belligerent personality, witnessed through his hostile and aggressive attitude most times.

Suigetsu, despite being hasty in anger, has shown moments of keenness and a calm attitude, such as discerning Killer B's ability as a swordsman, as Suigetsu is one himself. Other moments were when he realised Sasuke used a space-time ninjutsu with Manda to escape Deidara's blast. He was also able to predict Killer B's attack on Sasuke, which would have been fatal if Suigetsu had not stepped in to block the blow.

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 Zabuza Momochi's Kubikiribōchō and joined Hebi only to take Kisame Hoshigaki's Samehada. He even went into great detail to explain about the seven swords to Jūgo, with a passionate tone to his storytelling. He also cares a great deal for his swords, shown when he went back to retrieve his Kubikiribōchō after losing it in the fight against Killer B. However, his passion doesn't seem to be entirely limited to the seven blades, as he also expressed interest in Darui's sword. His ultimate goal however, is to collect the seven blades, so he can reform the Seven Ninja Swordsmen of the Mist and become their leader. Along with this passion for collecting swords, Suigetsu is very mischievous and as such, takes great joy in foiling Karin's plans to be alone with Sasuke and has stated that it is his second favourite thing to do. By his own admission, Suigetsu has an impulse to cut things up, be it a person or relationships, as he does with Sasuke and Karin.

Suigetsu apparently also likes animals somewhat seen from his attempt to play with the talking ninja cats from the abandoned Uchiha warehouse at one point. He also lectured Sasuke on treating animals better after Sasuke used Manda to shield himself from Deidara's suicide technique, which resulted in Manda's death. Suigetsu also has what seems to be a chronic fear of Orochimaru, which is to be expected due to the latter imprisoning and experimenting on him. This fear was witnessed when Sasuke declared that he would revive Orochimaru and Suigetsu's ensuing attempt to dissuade him from doing so. When Orochimaru was revived, Suigetsu even refused to stay on the same side of the cave with him, retreating to opposite ends depending on where Orochimaru went. On the other hand while always being wary of Orochimaru and his intentions, Suigetsu willingly offered to help his former jailer attack Konoha and then later even referred to Orochimaru using honourific while obeying his orders.

While showing courage against such fearsome opponents like Killer B, even taking a tailed beast ball for his comrades, Suigetsu also has a cowardly side at times. Despite his confidence (if not arrogance), he would show a rather cowardly side when someone of a clearly higher calibre directs their killing intent at him, as he hid behind Orochimaru in fear during an exchange between Tobirama and Hashirama Senju. He also seems to retain a sarcastic sense of humour even in serious situations, this trait being exemplified when, as Kabuto was healing Sasuke, he asked Kabuto if he was trying to absorb Sasuke, and if he wanted to be 'Kabuke' or 'Sasuto'.

Appearance
Suigetsu is a lean-built young man of average height, straight white hair with a light-blue tint to it in the anime, almond shaped purple eyes, and like most of the members of the Seven Ninja Swordsmen of the Mist, he has pointed teeth — one of which sticks out even when his mouth is closed. He wears a purple, sleeveless shirt with blue pants, sandals and a belt around his waist with water bottles attached to it.

He also wears another belt strapped to his chest which he uses to carry the Kubikiribōchō. Due to his special body, Suigetsu is able to alter his form at will, usually to aid in his techniques and when rendered unconscious, he is reduced to a jelly-like state. Whenever he is seen recovering from these unconscious states he is placed in a large tank of water and resembles a fish-like being.

Years later, Suigetsu opted to wear a dark, high-collared button down attire which had light-coloured, upturned sleeves. He wore two belts around his waist, a simple one and another larger one with two pouches — one at each side.

Abilities
Suigetsu is a capable fighter, or at least very confident in his abilities, since he has threatened Sasuke on more than one occasion and was capable of stopping Jūgo's rampage with little difficulty. Kisame has noted him to be a child prodigy in the art of murder, and that he is practically the reincarnation of Zabuza. Suigetsu was even shown able to briefly go up against Killer B, a perfect jinchūriki, while in his Tailed Beast Mode. In the anime, Suigetsu also demonstrated capable taijutsu skill, being able to fight off hundreds of foes unarmed.

Hōzuki Clan Techniques and Nature Transformation
As a member of the Hōzuki clan, Suigetsu is well versed in the clan's secret Water Release technique to transform his body into a liquid form, and to return to his solid bodily form at will. This ability also allows him to change his body shape, giving him the ability to increase the size of his limbs, thus proportionally increasing his strength if necessary. It also makes striking him somewhat difficult; since he is made of liquid, any regular strike will go right through his watery form. When struck, part of the water he turns into can also split from his body, and be manipulated, for example, making a water blob around one's head to drown them.

As his body is water, he is also capable of merging with already existing water to increase his attack range, as seen when he fought against Killer B, and utilise it for large scale Water Release techniques. When he passes out he enters a jelly-like state, as seen in the battle against Killer B. Also he can fire compressed, highly pressurised water bullets from the tips of his index fingers, that can cause great damage, able to fire it from both hands. A supplementary usage of his techniques is the ability to gather information via water such as rain, seen when he learned about the Fourth Shinobi World War after his imprisonment. In the anime, Suigetsu is also shown capable of creating clones made of water.

Suigetsu is seen carrying water bottles with him, as he frequently needs to consume water in order to stay hydrated. Due to his water-like body, he exhibits weakness against lightning-based techniques, as exhibited in his defence of Sasuke against Killer B's chakra-charged strike. Suigetsu is also capable of using Wind Release.

Kenjutsu
From his training days with the Seven Ninja Swordsmen of the Mist, Suigetsu is quite adept at wielding Zabuza Momochi's Kubikiribōchō. However, he lacks the high degree of physical strength Zabuza had, as carrying the sword around for long distances seems to tire him out. However, he partially makes up for this with his Hydrification Technique, which allows him to expand the muscles in his arms to help him wield such a heavy weapon with more ease. In addition to his own abilities, Suigetsu also has a good perception for swordsmanship skills, as he saw Killer B was a skilled swordsman almost instantly after the fight began. Suigetsu also seems to be very fast witnessed when he got away from the Fourth Raikage's assault against Jūgo and almost got C from behind unexpectedly until Darui stopped Suigetsu from landing his assault and he was fast enough to intercept Killer B's attack on Sasuke. He is also skilled as he was able to clash toe-to-toe with a powerful opponent like Darui even with the Kubikiribōchō broken in half.

Itachi Pursuit Mission
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. After threatening Sasuke, gesturing his hand to perform his clan's Water Gun Technique, he pointed out that he owed nothing to Sasuke for dealing with Orochimaru as there were many who wanted to do it and it was just a case where Sasuke was able to, because he was always in close proximity to Orochimaru. Suigetsu nevertheless agreed to join him in the hopes of meeting Kisame and taking Samehada for himself. Once they left, Suigetsu had Sasuke take him to the Land of Waves to retrieve Zabuza's Kubikiribōchō from his grave. In the anime, 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.

After Kubikiribōchō was retrieved, Suigetsu and Sasuke 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 Ginji was. Recognising 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.

Fated Battle Between Brothers
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, 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.

Pain's Assault
Hebi, now renamed "Taka", began working with Akatsuki. They went to Kumogakure and confronted Killer B, the jinchūriki of the Eight-Tails. Suigetsu attacked him first, but was quickly disarmed. Both Jūgo and Sasuke's individual attempts at subduing Killer B failed as well, and Sasuke would have suffered fatal injuries had Suigetsu not intervened to spare him a finishing blow from the jinchūriki. However, Killer B's electric attack overwhelmed Suigetsu, cleaving a substantial tear in his sword, and it would have severed in half had Sasuke not nullified the attack in time.

After Karin healed Sasuke, Suigetsu, together with Jūgo and Sasuke, engaged Killer B once more to no avail. At one point, Suigetsu succeeded in immobilising Killer B providing an opportunity for Sasuke to use a lightning attack. Unfortunately, to keep Killer B held, Suigetsu voluntarily received Sasuke's lightning technique as well, sustaining considerable damage.

After severely wounding Sasuke, Killer B invokes his tailed beast form in order to deal with the rest of the group. Suigetsu, thrown into the water earlier, emerged, using the body of water, to save his team-mates from what would been a devastating blow. Keeping the Eight-Tails at bay momentarily, Suigetsu valiantly told his weakened team members to escape, though somewhat amused that he was risking his life for them. When Killer B tried to use a Tailed Beast Ball on the team, Suigetsu used himself as a shield, keeping his team-mates safe.

Although Suigetsu was left unconscious, he managed to gain the time Jūgo needed to revive Sasuke. By unleashing Amaterasu on the Eight-Tails, Sasuke was able to turn the tide, at last successfully capturing the Eight-Tails jinchūriki. 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
Once healed, Taka set out for Konoha. Along the way they were intercepted by Tobi, who informed them of Konoha's destruction and their failure to capture the Eight-Tails. He convinced Sasuke to go to the Kage summit to kill Danzō, so Zetsu led them to the Land of Iron. Upon their arrival Suigetsu scouted the area, in order to find a way to the summit, but he found that there were too many samurai patrolling the area. Jūgo found them an alternate route, where they were attacked by the samurai, having been exposed by Zetsu. As Sasuke killed their attackers, Suigetsu pointed out that he (Sasuke) was doing the very thing he forbid him to do. The Fourth Raikage soon arrived to fight Sasuke and Suigetsu tried to help, but the Raikage breaks his Kubikiribōchō in half. He used what remained of his blade to fight Darui, and was able to hold his own, until Darui infused his own blade with electricity, allowing him to overpower Suigetsu and pin him to a wall. When Sasuke destroyed the room they were in, Suigetsu was freed. He retrieved his sword and regrouped with Jūgo. They contemplated following Sasuke and the Raikage, but decided that it would be too dangerous. Instead, they dressed up as samurai to gather information while avoiding drawing attention to themselves, at Suigetsu's suggestion. They were quickly detected, and Jūgo stated that it wasn't the best plan.

Fourth Shinobi World War: Confrontation
As the war was being waged, Suigetsu and Jūgo escape their cell in the Land of Iron, having taken care of the guards, and stating that security had gotten looser. Suigetsu said he wanted to go looking for his Kubikiribōchō, to which Jūgo agrees to help. He then states that Jūgo is nicer than Karin, and then they decide to look for her as well. During their search for the sword, Jūgo asks why Suigetsu, being a person who gets bored easily, is so particularly obsessed with those swords. Suigetsu then reveals his dream of reforming the Seven Ninja Swordsmen of the Mist and becoming their leader.

Fourth Shinobi World War: Climax
Suigetsu and Jūgo escape from the samurai compound. They walk through a forest and discuss their plans. Suigetsu tells Jūgo that even if they reunited with Sasuke and Karin, it wouldn't be a grand reunion of sorts as Karin wanted Sasuke to herself in order to seduce him. As they continue onwards, Suigetsu tells Jūgo that they'd continue to get in Karin's way which was his second favourite thing to do after collecting swords. They proceed to head towards one of Orochimaru's hideouts. On the way there, they learn about the war. After arriving, Jūgo and Suigetsu have a brief conversation before Jūgo loses control and attacks Suigetsu, who is unharmed. Breaking into a wall, Orochimaru's secret room is discovered and within it, Suigetsu finds a scroll — the contents of which greatly shocked him. He took the scroll and stated that it could be beneficial to Sasuke, and to possibly allow them to gain control of the war.

Later, when Sasuke was left to contemplate his future actions after Itachi's soul had been released, Jūgo and Suigetsu broke through the roof of the cave, and declared that they had finally found him. Suigetsu examined Kabuto's body and expressed his disgust at Kabuto's navel-snake while Jūgo found Anko Mitarashi unconscious on the cave's floor. When Sasuke asked them their purpose of coming there, Suigetsu handed him the scroll — the one with which he exclaimed that their group could use that to rule the shinobi world with — and making him cognisant of reincarnated Madara's presence even though Itachi forced Kabuto to release the Impure World Reincarnation, which left Sasuke dumbfounded.

After Sasuke declared that he would revive Orochimaru, Suigetsu vehemently opposed this and tried dissuading Sasuke from his actions to no avail. When Orochimaru emerged from Anko's Cursed Seal of Heaven, Suigetsu retreated behind Kabuto's immobile body and sheepishly greeted his former captor. Shocked when he heard that Orochimaru was not interested in the war that was going on, Suigetsu then quickly relocated to the other side of the cave when Orochimaru moved towards Kabuto. Declaring that Orochimaru was going to kill Kabuto, he is corrected by Jūgo who noted that Orochimaru was only draining his own chakra from within Kabuto. He later listened on, confused as Orochimaru told Sasuke that they were going somewhere he knew well.

Arriving in Konohagakure, Suigetsu and the others sensed Naruto Uzumaki's chakra from a great distance away. Unperturbed, Sasuke told them to press on to their destination. Arriving at a dilapidated temple, the group enters the shrine and retrieved a mask. Glad to have left the temple which spooked him somewhat, Suigetsu conversed with Orochimaru about his own desire to crush the village, as they re-entered Konoha and headed towards the Naka Shrine. Heading into the secret hall beneath the ruin, Suigetsu watched on as Orochimaru began the ritual, and assisted by subduing one of the White Zetsu clones which Jūgo activated using natural energy. Prying open the clone's mouth, Suigetsu prepared to clone for Orochimaru's abdication from his own wounded body and into the clone's. Suigetsu later watched on as the four previous Hokage are reincarnated. Marvelling that Hashirama Senju stood before him, Suigetsu was later underwhelmed by how contrary the legend's personality was. He would later cower in fear, however, as Tobirama and Hashirama faced-off when the former wanted to attack them because of Sasuke's declaration to exact revenge on the village. Stuck in a half-liquid form, Suigetsu cowered behind Orochimaru as the Naka Shrine is almost destroyed around them from the encounter.

Listening on as the dialogue between the Hokage and Sasuke, Suigetsu is shocked to hear that Sasuke was joining to battle to stop Madara and protect his brother's sacrifice. Questioning Jūgo as to what he would do, Suigetsu was further dismayed to hear that he would remain by Sasuke's side. Not wanting to be caught in a war with what he considered the four most powerful reincarnations and three monsters, the young man schemed to escape as soon as he got an opportunity. His escape, however, was cut off by Karin's appearance where they were as she began to pulverise the confused Suigetsu. The young man would later note that now an idiot had joined the fray. Afterwards, he accompanied Orochimaru and Karin to the location of the five Kage, watching as the former commented on Tsunade's bad condition.

Commenting on the size of the slugs before them, Suigetsu wondered just how much salt would be needed to kill them which struck up an argument between him and Karin. After being threatened by Orochimaru, the two made their way towards Tsunade to heal her. Suigetsu pieced the Hokage back together while Karin healed her. Afterwards, the trio took their leave from the Hokage, making their way to the main battlefield.

Birth of the Ten-Tails' Jinchūriki
Upon arriving on the battlefield, Suigetsu greeted Jūgo and Sasuke before commenting on the size of the Ten-Tails' tree form and just how long it would take to cut it down. Interrupting Karin's daydream about Sasuke, Suigetsu reminded her that her role on the battlefield would be to to help in the recovery of the shinobi. After the Allied Forces managed to separate Obito from the Ten-Tails, a Tobi appears and ravaged the forces. Suigetsu and his team then engaged the Zetsu. Though first surprised as Karin led the charge manifesting Adamantine Attacking Chains, he follows up her attack with his Water Gun: Two Guns technique, which destroyed part of Tobi's head revealing someone inside the clone. The team is able to elude their assaulter and with that, hastily made their way to where Sasuke was, to which Karin grimly said a sinister chakra was near him.

Upon arriving, they discovered the new chakra signature was from Kabuto, having escaped the loop of Itachi's Izanami. While Suigetsu assumed Kabuto was trying to assimilate, having merged his being with Sasuke, Kabuto plainly stated that he no longer desired Sasuke, rather was attempting to heal him. Orochimaru asks his former assistant why he was doing this, Kabuto explained that his experience under Izanami's power restored his clarity on who he really was, now merely wishing to return to Konohagakure orphange he grew up in. Suigetsu didn't believe Kabuto as he helped instigate the war in the first place. Kabuto solemnly admitted his mistake, selfishly involving the world in his own personal problem and sought to correct it. Eventually, Kabuto succeeded in healing Sasuke, who quickly returned to his feet and was ready to resume the battle. Suigetsu and the others were later caught in the Infinite Tsukuyomi cast by Madara.

Kaguya Ōtsutsuki Strikes
Ultimately, he and the rest of the world were freed from the genjutsu by Naruto and Sasuke after they ended the war.

Blank Period
After the Fourth Shinobi World War ended, Suigetsu, Karin and Jūgo returned to Orochimaru as his subordinates, Karin being reassigned to a different hideout.

Sasuke Shinden: Book of Sunrise
Suigetsu meets with Sasuke again since the war ended a few years ago. Sasuke arrives at the hideout to collect information on the Dark Thunder Group from Orochimaru; however, he doesn't stay long to speak with his former team-mates. Suigetsu tells Jūgo and Karin that he is curious why Sasuke continues traveling and refuses to officially settle down in Konoha; Karin explains that Sasuke's Sharingan and Rinnegan earn him enemies and he is avoiding the village to protect it.

Naruto Gaiden: The Road Illuminated by the Full Moon
Years later, he assisted Orochimaru in the experiment that resulted in Mitsuki. After five failed attempts to bring out Mitsuki's independence, Suigetsu feigned an attack on him, testing to make sure that the boy's ninja skills remained intact after having his memories erased so many times. After satisfied that Mitsuki was fine, he brought the boy to Orochimaru for a final test disguised as a mission.

Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
When Sasuke, Naruto Uzumaki, Sarada Uchiha and Chōchō Akimichi came to learn about Shin Uchiha, they were greeted by Suigetsu and Jūgo. The group then followed Orochimaru into the depths of the hideout to discuss the situation. Sarada, however, asked Suigetsu about Karin's whereabouts where he replied that Karin was in a different hideout. Suigetsu, much to his shock, was found it hard to believe when Sarada discussed with him in the possibility that Karin was her biological mother; this made Suigetsu recall Karin's previous intimate approaches she made with Sasuke in the past. Sarada requested for his assistance in checking whether Karin is her birth mother or not. Suigetsu found a strand of Karin's DNA in her desk (not knowing that it was Sarada's umbilical cord), and used it to run a test with that of Sarada's, which revealed a perfect match; Suigetsu also commented in the similar facial features between Sarada and Karin. Feeling awkward, Suigetsu left, but not before Naruto, who is listening on their conversation, scolded him for bringing this situation up for the young Uchiha, where he then claimed that it wasn't his fault but Sasuke's.

Later, Suigetsu joined Orochimaru in aiding Sasuke to find Shin. Sasuke then activated his Rinnegan and prepared to go in his Susanoo.

Some time after Shin's defeat, Karin scolded Suigetsu for touching her belongings, explaining to him that he had used Sakura and Sarada's umbilical cord in the DNA test. Further elaborating the circumstances of Sarada's birth, she ultimately confirmed that Sakura was Sarada's mother. Karin then demanded for Suigetsu to apologise to Sarada for his mistake and ordered him to send Sarada a new pair of glasses.
