Maito Gai

Gai (マイト・ガイ) is a jonin-level shinobi of Konohagakure, and a major supporting character of the series. He is also the leader of Team Guy which consists of Rock Lee,Hyuga Neji & Tenten.

Background
When Guy first took the Chunin Exams, he was placed in a team with Ebisu and Genma. During the second stage of the exams in the Forest of Death, Guy's team came face-to-face with Team Minato. Before Obito who had taken the lead could attack them, Guy unceremoniously kicked Obito in the face, inadvertently saving the boy from choking on a sweet. During the third stage of his first Chunin Exams, Guy faced Obito once again where after trying to give Obito the nice guy pose was met with a thumbs-down. Though Guy defeated Obito, he faced his own loss against Kakashi in the next round. Since then, having befriended him, Guy sees Kakashi as his sworn rival.

In the anime, after the events of Kanabi Bridge, Guy was assigned to a mission with Kakashi and Rin. With the situation looking grim, Guy used himself as a scapegoat to allow his comrades to escape but is soon joined by Kakashi. The two shinobi are eventually able to stave off the Iwa-nin until Rin returned with reinforcements. The events of this mission would cause the two to build great trust in one another. But regardless, Guy still competed regularly with Kakashi, even in the moments preceding the Nine Tails attack on Konoha.

During Nine-Tails' attack on the village, Guy was among the young ninja barred from participating in the defence of the village by Kurenai's father and other older shinobi. In later years, before Guy became a jōnin-sensei, he heard rumours of a Ninja Academy student that was determined to become a ninja despite every indication that he couldn't. When this student, Rock Lee, eventually became his own student, Guy became determined to help Lee become a taijutsu master, as Lee did not have the skill to use ninjutsu or genjutsu.

Personality
Known for his thick eyebrows, green jumpsuit, and shiny bowl haircut, Guy often refers to himself as "Konoha's Sublime Green Beast of Prey" (木ノ葉の気高き碧い猛獣, Konoha no Kedakaki Aoi Mōjū). He has many mannerisms unique to him in the series that are meant to be seen as corny and old-fashioned, a reference to common clichés of "youth" (青春, seishun) in the anime. Guy is also known for going on about the "Power of Youth".

Guy has problems remembering the faces of persons he does not interact with frequently, best seen with his frequent fights with Hoshigaki Kisame, and also his fight with the Three Ryudoin Brothers. Obito has even mentioned this trait in Guy. It was explained that this may be due to the fact that Guy always looks to the future instead of dwelling in the past.

Guy is best known for his "nice guy pose", which consists of giving a thumbs up, winking, and smiling with teeth so white they give the proverbial "ping". This action is often used by both Guy and Lee to indicate commitment to a statement they had just made, their highest form of a promise. Despite these odd mannerisms, Guy has shown to be capable of being as serious, ruthless and decisive as a mission's success demands if needed, as seen during the Invasion of Konoha and his battles with Kisame. He is noted to be quite scary if switching to "serious", but very reliable.

Guy is on good terms with all of his students, but takes particular interest in Rock Lee, who reminds Guy of himself in his youth in retrospect that both are considered losers and have to work hard to achieve their goals. As such, Guy puts much more interest in Lee's training than Neji's or Tenten's, continuing to train Lee long after the others have retired for the day. Because of this, and due to Lee's unyielding desire to master the art of taijutsu, the two have developed a father-son relation that has pushed Guy to teach Lee a number of dangerous and forbidden techniques, giving the stipulation that Lee can only use them under specific circumstances. Although Guy knows of the dangers that teaching the techniques to Lee entails, Guy wishes for Lee to be able to prove himself to be a splendid ninja, and, as such, turns a blind eye to the repercussions. However, overall, Guy is a very attentive and dedicated instructor, who does everything in his power to make sure that all three of his prized students receive proper instruction in their own particular fields.

Guy, and, by extension Lee, lives his life by his own "My Rules" philosophy, which involves setting tougher goals for failure so something good comes of it. For example, he vowed to walk 500 laps around Konoha on his hands if he lost a simple game of rock, paper, scissors with Kakashi, and proceeded to do so upon losing, even though people stopped paying attention eventually. Lee's willingness to train in the same manner as Guy seems to have caused him to surpass his master's stamina, as by the end of Part I, Guy has difficulty keeping up with Lee, lamenting that he is not as youthful as he once was.

Guy's teacher-student relationship with Lee also carries distinct attributes, such as when Guy will punch Lee for a slight infraction of a rule. After Guy assigns Lee an arduous training task as punishment, meant to recapture Lee's focus and discipline, the two may then burst into tears and affectionately embrace, in brief regret for the strong blow Lee was given. Guy often attempts to act in a similar way towards his other two students, although Tenten is usually resigned and more willing to take part in his antics than the more stoic Neji.

Guy is the self-proclaimed rival of Kakashi, though the latter is indifferent to the former's annoyance. Since first losing to Kakashi during the Chunin Exam, Guy randomly challenges Kakashi to contests of skill, and has acquired a record of 50 wins and 49 losses in doing so (50 wins and 51 losses in the anime). Given that the contests that make up this figure are so varied (ranging from Rock, Paper, Scissors to running races), this is not much of an achievement on Guy's part nor an accurate comparison of respective combat power. Nevertheless, Guy is proud of his record. Their competitions seem to, in part, be founded on the fact that the two are polar opposites. Guy has shown to be more easily excited compared to the more laid back Kakashi. He also relies mainly on taijutsu, in contrast to Kakashi's ninjutsu specialisation, and had to work tremendously hard to reach his level of prowess, whereas Kakashi's natural talent and Sharingan made it easier for him to improve. Nevertheless, both men are great friends and also have the utmost faith in each other seen during the Fourth Shinobi War, when they entrusted the protection of their blind spots to each other. This was also expanded on in the anime, where Kakashi told Tsunade that he would need a second-in-command during the war and wanted Guy to serve that purpose. Guy's and Kakashi's level of friendship was such that when faced with five fully transformed tailed beasts preparing to fire their Tail Beast Ball in close proximity, he was more than willing to activate the last of the Eight Gates to protect Kakashi, despite the fatal repercussions.

Guy can't handle sea rides and easily gets seasick when he has to travel by boat or ship. After getting over this and attempting the challenge at the Falls of Truth, Guy's "inner self" rebuked him for being too old yet still maintaining a hyper-active demeanour, adding that it is not healthy for old men like him to push themselves so hard.

Appearance
Guy is a tall and well-built man with high cheek-bones, thick eyebrows and black hair cut in a bowl style. Guy also wears a green jumpsuit, orange striped leg warmers and the standard Konoha flak jacket, though it's normally unzipped and has only been seen zipped up during the Fourth Shinobi War. His forehead protector, is on a red cloth and is worn around his waist, like a belt. When he was a genin, he wore the same style of clothing with bandages wrapped around his hand and a brown scarf tied around his neck. His hair also had the shape of his signature bowl-style though a bit longer. When he became a chūnin, he donned the flak jacket, got his signature haircut and also removed the scarf.

His protégé Rock Lee has modelled himself after Guy and as such both men bear a striking resemblance: both naturally having thick eyebrows and the same hair cut.

Abilities
Guy is one of Konoha's most powerful ninja, and a taijutsu master. Despite considering himself a loser as a child, Guy is a very talented ninja, graduating from the Academy at age 7 and becoming a chunin at age 11. Itachi has, on numerous occasions, warned others against underestimating Guy. A warning from such a powerful ninja is an indicator that Guy is an excellent combatant. A testament to his skill as a ninja was him single-handedly defeating the extremely dangerous Akatsuki member, Kisame. This is later reaffirmed when Kakashi trusts him to take on the Six Tails alone during their battle with the reincarnated jinchūriki.

Taijutsu
Might Guy is an extremely accomplished taijutsu master, with advanced knowledge if not, skill in various styles and taijutsu techniques. As noted by Kisame Hoshigaki, it is very rare for one to reach Guy's level of prowess. With his skill, he is able to fight off countless high-level ninja unarmed as demonstrated during Orochimaru's invasion of Konoha. Through his "My Rule" philosophy, Guy has gained a strong and enduring body with very high chakra reserves and immense stamina by constantly pushing his own limits, allowing him to recover from extreme exhaustion in an alarmingly short period of time and utilise the style known as "Strong Fist" to its full potential. In addition, his intense training has given him such tremendous speed that his movements can seem like he's disappearing to unfocused eyes, and strength capable of easily ploughing a full-grown man through a solid, stone wall with a single hand: accomplishing both feats without the aid of chakra-enhancement. It was even shown in Part I that he was capable of dispelling Gaara's chakra-infused sand with a simple wave of his hand.

Eight Gates
Guy is able to utilise and open the Eight Gates — a feat that is difficult for even some of the most talented ninja — and has shown the ability to open at least seven of the eight gates and has been stated to be able to open the eighth as well. His mastery is enough that he is capable of utilising several kinjutsu after opening the gates, making him truly a formidable force on the battlefield.

When opening the sixth gate, Guy can utilise the Morning Peacock a technique so fast that his hands were set ablaze by sheer speed and friction. When unlocking the seventh gate, he can utilise a one-hit kill technique called Daytime Tiger, which is strong enough to completely overwhelm Uchiha Madara's complete Susanoo. Because of the potential severe bodily damage opening the gates can cause, Guy has, like he has told Lee, decided that he will only open the gates if it is a life-or-death situation, or he is protecting someone dear to him. However Guy's extremely intense training routines has allowed him to handle opening the gates for longer periods of time, able to endure the sixth gate with only noticeable exhaustion, as well as resist the damaging after-effects of the seventh gate long enough to continue fighting for a short period of time.

Bukijutsu
Aside from his taijutsu repertoire, Guy is also highly skilled in a variety of weapons styles, having trained Tenten extensively in their respective usages. His personal weapon of choice is the nunchaku, but only resorts to using them when absolutely necessary, and from what has been shown he uses them with great ferocity and power, matching Kisame's unique swordplay. Aside from his regular set, Guy keeps a second, special pair of nunchaku with him, called the Soshuga, which he used to skilfully battle Obito. These were durable enough to smash a large rock into pieces, and trade blows with Obito's gunbai.

Other Skills
Unlike Lee, who specialises in taijutsu because he cannot use ninjutsu or genjutsu, Guy is fully capable of using the other two forms of ninja abilities, as he is proficient enough to dispel a high-level genjutsu. He makes a conscious effort to rely almost exclusively on taijutsu; going so far as to use regular disguises instead of the Transformation Technique. In the few instances that he has used ninjutsu, it has usually been off-screen, such as when he summoned Ningame prior to his first appearance. The first on-screen use of ninjutsu that he has used was once again summoning Ningame in mid-air as he chased after Kisame. In the anime, he has been shown summoning a much smaller messenger tortoise to deliver an SOS to allies in a dire emergency. Despite his limited use of ninjutsu, Guy is nonetheless knowledgeable of powerful techniques, recognising and commenting upon the reincarnated Hokage's use of the Four Red Yang Formation during the Fourth Shinobi World War.

In his rivalry with Kakashi, Guy has developed an effective counter against Sharingan-users: by focusing on their feet, Guy can both predict the movements of the enemy and negate the Sharingan's necessity of having eye-contact for genjutsu techniques. Currently, Guy is the only ninja who can use this technique, though he has taught the basics of it to Asuma, Kurenai, and also Kakashi. In the anime, it is shown that Might Guy is knowledgeable in herbal remedies, regularly preparing them for Lee to help further his training.

Introduction arc
He is seen with the other Jonin,when they learn that Sauke is the last member of the Uchiha Clan.

Chunin Exam arc
Guy made his début shortly before the start of the Chunin Exams, stopping Lee from using the Front Lotus on  Sasuke. He punished Lee for attempting to use a forbidden technique before having an emotional embrace with him, much to Team 7's disgust. He appeared again during the preliminaries to watch his students' matches. He showed anger at Temari's treatment of Tenten after their match, and disappointment with Neji when he tried to kill  Hinata, having earlier instructed him to not make the match into a vendetta with the Hyuga Clan.

Guy then took the role of Lee's coach prior to his match with Gaara, giving him general advice on what to do. During the actual fight, Lee continually found his fighting level to be inadequate in defeating Gaara, and each time Guy gave his consent for Lee to increase the strength of his attacks. When Lee began to run out of options, Guy allowed Lee to open the first five chakra gates in order to defeat Gaara. Although Lee did so, his efforts were unsuccessful, and he was left heavily injured. When Gaara was about to kill Lee, Guy stepped in to stop the match, not willing to allow anything to happen to Lee. As Lee was taken away to be healed, one of the medics informed Guy that the injuries to Lee's body were so severe that he would never be able to fight as a ninja again. Guy was crushed by this prospect, and regretted ever teaching Lee so many dangerous techniques.

Invasion of Konoha arc
A month later, when Gaara tried to finish off a hospitalised Lee, Guy once again intervened to save his beloved student. When Lee recuperated to the point of being able to watch other matches, Guy accompanied him to the final round matches, only to be surprised that Neji was defeated by Naruto. He later marvelled at Sasuke's ability to have replicated Lee's base speed from their sole encounter, but noted that it was much more crass than Lee's. When Sasuke unveils the Chidori, it confirms Guy's suspicions as the reason why Kakashi had Sasuke replicate Lee's speed, though he is criticised for what his training did to Lee after Guy tried to criticise Kakashi for the same reason of teaching his student a dangerous technique.

When the invasion of Konoha began, Guy wanted at first to aid the Third Hokage, but instead teamed up with Kakashi in repelling the invading forces and protecting the unconscious spectators. Despite the seriousness of the situation, Guy still made clear that he was considering this another challenge against Kakashi over who could take out the most enemy ninja. After Kakashi gives orders to Naruto,Sakura,Shikamaru & Pakkun to go after Sasuke, Guy intercepts an Oto-nin and uses him to create a hole in the wall of the arena, effectively giving the genin an exit. He later attended the Third's funeral.

Search for Tsunade arc
When Kakashi was about to be defeated by Akatsuki members Itachi and Kisame, Guy arrived in time to repel Kisame and save Kakashi. When Guy stated that he had called for back-up, the two left, unwilling to start a war. Guy got Kakashi medical attention, before following the two. When he finally caught up to them, he made an attempt at a sneak attack in order to avoid Itachi's Sharingan. In doing so, he accidentally attacked Jiraiya, Itachi and Kisame having already left. After apologising for his mistake, Guy learned that Jiraiya was looking for the talented medical ninja Tsunade, and asked that Jiraiya be sure to find her, in the hopes that she would be able to heal Lee. Before leaving for Konoha with an unconscious Sasuke, he gave Naruto his spare green jumpsuit, as a reward for his determination. Jiraiya was, naturally, unsettled by this, but Naruto was ecstatic.

Once Tsunade was found, and returned to Konoha, she found that the operation that would heal Lee had a 50% chance of death. Although Lee was reluctant to risk his life, since that would mean he couldn't be a ninja, Guy convinced Lee to go through with the operation, saying that all the work Lee had done meant that he would definitely survive. In the event that Lee did die during the operation, Guy said that he would die too, as he had no point in living if he couldn't help Lee become a great ninja. Lee's operation was a success, and Guy visited him daily until he was ready to start training again.

Pre Shippuuden Filler arc
In the anime, Guy was the only jōnin to receive a considerable amount of screen time. In the Mizuki Strikes back arc, he was seen training with his students,but was very tired from doing it.

When Lee's dōjō went unchallenged in one arc, Guy challenged Lee himself disguised as a stranger. Although the disguise was very bad, Lee never caught on that it was actually Guy.

In the Third Great Beast Arc, Guy began training a visiting ninja named Yagura. Yagura trapped Guy and Lee in a castle together, and forced them to fight each other through artificial, mute proxies - they figured this out by communicating through Morse code, then broke out by opening the first five gates, the stress of their high-speed attacks causing the constructions to break apart.

Later, in the Trap Master Arc, Guy led Konoha's available jōnin to stop a suspected invasion by Takigakure, though in reality the Takigakure forces were just having a training exercise.

Kazekage Rescue arc
Team Guy was assigned by Tsunade as back-up to assist Team 7 in rescuing Gaara. On their way to meet Team 7, Guy again encountered Kisame, who wanted to take revenge on Guy for hitting him during their last encounter. Guy, however, didn't seem to remember Kisame, which greatly agitated the Akatsuki member. Kisame was strong enough to overcome the entire Team Guy, but when he succeeded in imprisoning Guy's students in respective water prisons and nearly drowned Tenten, Guy opened the sixth chakra gate and used his Morning Peacock to defeat Kisame. As the group examined Kisame's corpse, they found that it was not Kisame, but merely a body double; namely a former Sunagakure ninja called Mukade.

Upon reuniting with Team 7 and reaching the Akatsuki hideout, Team Guy was assigned to disable a barrier surrounding the hideout's entrance. Although they completed the task, they were forced to fight clones of themselves, though each member eventually succeeded in defeating their lookalikes. Returning to Team Kakashi, Guy and his students uncover Deidara hiding in the bushes. Confronting the Akatsuki member, who subsequently escapes, the shinobi are forced to run for cover when their opponent seemingly committed suicide. Kakashi, however, was able to warp the blast away using Kamui. After Gaara was rescued, Guy carried Kakashi back to Konoha on his back, because the latter was too exhausted to walk there under his own power due to his overuse of Mangekyō Sharingan. Uzumaki Naruto,Haruno Sakura,Hyuga Neji and Tenten were deeply irritated by the disturbing sight, although Guy didn't seem to notice, and instead had a race with Lee to see who could reach Konoha first.

Sasuke & Sai arc
In the anime, he and his team appear in the very beginning of this arc.

Hidan & Kakuzu arc
In the anime, he was seen standing beside Kakashi, mourning Asuma's death.

Three Tails arc
He is mention by Lee.

Invasion of Pain arc
When Pain's invasion of Konoha began, Team Guy was away on a mission. During a pit-stop on their return home, they noticed a number of birds apparently escaping from the village. They rushed to the village, and found it to be in ruins. They found Hinata badly injured, and got her medical attention. After the team finds Hinata, Katsuyu later informs them that Naruto was fighting with the last Pain and Guy insists that he and his team should provide back-up, but Katsuyu mentions that Naruto does not want anyone else to get involved, which angers Guy. They were then later present with the other villagers celebrating Naruto's defeat of Pain.

Konoha History arc
Tenten and Neji Hyūga arrive at a Konoha Tool Research Lab for more tools due the weakened military power after Orochimaru's invasion. Might Guy has Naruto join Team Guy on a mission with Rock Lee in the hospital. For the mission, Guy assigns Tenten as captain of the team. Team Tenten arrives at the lab and ask the tool maker, Iō for more tools. He shows them some of his latest tools though all of them are completely useless. The impatient Tenten then demands for the tools they need from them. The team checks on Iō's progress but went missing. Neji uses his Byakugan and finds Iō hidden deep under the lab. They get past all of the traps placed with Tenten's help and find a stash of Iō's tools. Iō is impressed with Tenten's skills and decides to test her with his latest invention when suddenly one of the traps outside is triggered.

They all run outside to see two ninja named Gameru and Kusune who demand more tools from Iō who refuses. Naruto and Neji decide to fight them and they summon two prototype tools of Iō's, Dakō and Tsurukame. Iō's apprentice, Shōseki confesses that he sold them the tools. With Naruto and Neji struggling with the two ninja, Iō has Tenten use his latest invention, Jidanda. Tenten uses exploding tags to lift the giant iron ball in the air with the recoils of the explosions and throws Jidanda at Gameru and Kusune. Though the attack was blocked by Tsuru-Kame, the Jidanda reveals exploding tags inside and explodes on Gameru and Kusune. After the fight, Iō takes Jidanda back from Tenten, who was hoping to keep it, to make more adjustments to it. Naruto and Neji cheer her up with complementing on how great she was in the fight. The flashback ends and Tenten hopes that Iō finished the adjustments to Jidanda.

Lee arrives at Tsunade's tent and asks Sakura how she is feeling though Sakura nods her head no. Lee brought a bottle of medicine Guy made for her to get well and has a flashback of when Tsunade told him he could no longer become a ninja. Naruto and Sakura find Ino at the hospital who tells them they have a mission together. They say their hellos to Lee in his room. Lee accidentally drops his youth drink bottle that Guy made for him but catches it and drinks it all, putting Lee is dismay. With the drink, Lee would be able to recover a little faster. Naruto decides to go see Guy and have him make another drink. Guy appoints Naruto to a mission to go to Mount Jofuku to retrieve the Jofuku Flower, a medicinal herb said to cure any illness and the missing ingredient in the medicine he is making. Before setting off, Naruto puts on the green jumpsuit that Guy gave him.

Naruto meets Sakura and Ino at the village gate who were waiting to leave with Naruto to their mission. Naruto tells them of his mission at Mount Jofuku which is also the place of his team's mission. The team takes a break at a small tea soup where the old lady there warns them of Jofuku Forest that has ghosts of dead ninja wandering about. The team head to Jofuku Forest where they find a large sign blocking a path. Naruto decides to go through it with Sakura and Ino following him, having no choice. Naruto finds the Jofuku Flowers but upon pulling them causes some sand appearing that forms into Gaara after the mention of him from Ino. The team are shocked to see "Gaara" and decide to retreat but suddenly the Gaara impostor starts attacking Naruto, having the same abilities as the real Gaara. Ino tries her Mind Body Switch Technique on the impostor but cannot sense a consciousness in it. Naruto destroys the Gaara impostor with the Naruto Uzumaki Combo< and a Rasengan. Suddenly they are approached by an old medical ninja from Konoha named Furofuki who is doing research in the forest.

Sakura asks Furofuki who or what was the Gaara impostor and she tells it was a Jofuku Flower, which assumes the form of the nemesis of whoever pulls it. They give Furofuki the letter that they were assigned to do and are given another mission by her to take loads of Jofuku Flowers back to Konoha. With final ingredient made, Guy is able to finish the medicine and makes a bowl full of medicine balls for Lee. Lee is shocked to hear that Sakura and her team did this and decides to recover as soon as possible. While Lee starts devouring the horribly tasting medicine balls, Guy does 1000 push-ups, not wanting Lee the only one to suffer and the flashback ends.

Chikara Arc
The Nine-Tailed Naruto clone tries to attack Dokku and the orphans, when Gai and Rock Lee arrive to repel it. While they fight the beast, Kabuto tries to control it, but to no avail. The rest of Konoha 11 arrive,Team Asuma's help. Sakura and Kakashi and Team Kurenai help Naruto. Tenten and Neji arrive, but are cornered by the reincarnated puppets. Kakashi chases Kabuto. The beast grabs Naruto to absorb chakra, which the Nine-Tails gladly shares. Hinata tries to defend Naruto, but is sent flying. After the beast absorbs Naruto's chakra, it grows in size and starts to devastate the Hachō Village, even firing a Tailed Beast Ball in far away, missing Yamato, Sai, Deidara and Hidan who are fighting outside the village. Dokku tries to save Naruto, who is still unconscious. Moments before the beast tramples them, Kabuto summons a snake to swallow both of them alive and retreats. While inside the underground hall in the Tonika Village, Naruto, unconscious and strangled by snakes, meets the Nine-Tails again in his subconscious.

The Konoha-nin investigates Kabuto's intention in the meanwhile. Shiseru remembers an earlier conversation between her and Dokku about the pros and cons of them adopting the kids. While the Nine-Tails tries to control Naruto, Dokku calls him, but gets shouted instead. Dokku asks Naruto what burden a powerful person carries and made Naruto choose the reason why he desires to be powerful, seeing flashbacks of his comrades of Konoha and Sasuke, leading to the seal inside Naruto to gain strength again. Dokku gives Naruto his forehead protector, stating that he believes in him. Meanwhile, Leo decides to save their teacher by giving the mysterious iron bars which were mentioned earlier by the Tonika Village Head. While inside the hall, Kabuto, along with two reincarnated puppets, approaches with Disonasu, revealed to have engineered Tonika's destruction. Disonasu pulls out a scroll from which emerges the item that he desired: the Saezuri.

While the Saezuri is revealed, learning that Disonasu employed Kabuto Yakushi to wipe out the residents of Tonika Village, Dokku tried to attack Disonasu, but stopped by a reincarnated puppet and restrained by a resurrected Takigakure shinobi. Disonasu also praised Naruto about defeating Pain, the one who scarred him and left him powerless, before kicking the boy repeatedly. Miina and the orphans came to The Hole to give the iron bars, but Kabuto's clone intercepted them. Meanwhile, the rest of Konoha 11, along with Kakashi, Shiseru, Yamato and Sai moved out to the area. Disonasu prepares the summoning of the "power" by putting the remaining iron bars while Naruto enters Sage Mode. Miina hums to the sound as the Saezuri is activated, causing the area Naruto is on, the Ama no Hoko, to rise above ground. Kakashi arrived on the scene, revealing Disonasu's past as a bloodthirsty murderer and former Akatsuki subordinate whose specialty is the field of Summoning Technique, having researched Impure World Reincarnatio with Orochimaru. Kabuto summons his puppets, the Nine-Tailed Naruto Clone, Hidan, and Deidara. Naruto faces off with the clone, while Deidara uses Explosive Clay to create a diversion and chase Naruto.

Disonasu escapes and Hidan faces Shikamaru. Deidara activates the Explosive Clay on the bodies of the resurrected individuals, as Hidan uses his ritual against Team Asuma, and Sakura got restrained by Hayate and the others. While Naruto relentlessly attacked the clone, he learned there is more than power. As Yamato restrained Disonasu, he activated the Saezuri, opening the area where Naruto faces the clone, draining the lake as an obelisk rises and creates a storm. After Hidan's clone body breaks down due to the shorten life spans of the snakes composing his body, Deidara is controlled by Kabuto to escape Kakashi. A lightning hit the area where the orphans are running, Miina pointing to the obelisk. When the storm expands towards Konoha, Tsunade goes out as the storm engulfs the Land of Fire. Naruto tried to stop Disonasu from ascending the tower, only to face his clone after he absorbed some of the tower's power and transformed a Hydra-tailed fox monster.

Absorbing the power within the Ama no Hoko, the Nine-Tailed Naruto Clone mutated into a hydra-tailed version of the Nine-Tails while sending Disonasu to his death. Overpowered, Naruto almost gave in to the Nine-Tails' offer for power when Minato's voice urges the boy to control the tailed beast as Naruto is engulfed in a six-tailed chakra cloak in the Nine-Tails' image. Over time, as he starts to lose against the clone, the Nine-Tails starts to take control over Naruto's body and assumes a seven-tailed jinchūriki state with Yamato trying to restrain it. At the same time, though followed by Kakashi Hatake, Kabuto Yakushi manages to take his leave in midst of the ensuing chaos. Dokku and Shiseru decide to deactivate the Ama no Hoko and say good-bye to the children. On their way there, they confess their love for each other and decide to get married if they survive before portions of the ground start to sink, with Dokku keeping Shiseru from falling.

By that time, Miina is able to get through Naruto, regaining control as he assumed a new form to save Shiseru after telling Dokku to go forward and stop the Ama no Hoko. As Dokku recalls the tune Miina hummed to change the sounds in the Saezuri to deactivate the tower, Naruto uses his new power to destroy his clone as the Ama no Hoko recedes into the ground. Everyone, including the Konoha 11 and children celebrate with Naruto.

Adventures at Sea arc
A team consisting of Yamato, Aoba, and Gai and three other unknown shinobi, set off with Naruto to the Land of Lightning, to confine him in an isolated location from Akatsuki in preparation for the Fourth Shinobi World War. The team travels to a harbour in the Land of Fire to travel by sea. Tsunade ordered them to take the long way so Akatsuki wouldn't attempt to capture Naruto. The boat the team takes is rather small one, so they won't get noticed. Some fellow Konoha ninja warn them about a sea monster that attacks any ship that goes into open water. Guy decides to sail out with Aoba to the water to fight the monster. Suddenly, the monster attacks Guy and Aoba, and they learn that it is a Giant Marlin summon from the Third Shinobi World War, roaming around the waters of the Land of Fire. As the marlin swims towards Guy, a fisherman named Yūsuke, tries to capture it. The fish destroys Yūsuke's boat and the fisherman is saved by Naruto. Holding Yūsuke prevents Naruto from performing any techniques and is left open. Yamato shields Naruto and Aoba distracts the marlin with the Scattering Thousand Crows Technique while they all escape.

At Yūsuke's hut, the Konoha ninja try to figure out why the marlin did not return home after the war. Yūsuke tells them to not interfere as he wants to capture the fish himself, to avenge his father who died trying to capture it. As the team is about to depart, Naruto wants to help Yūsuke avenge his father to which everyone agrees. The next day, Yūsuke comes out to see a new boat and fishing rod made by Yamato. The team sails out with Yūsuke to search for the marlin. The marlin appears and Guy opens the second of his Eight Gates to keep up with the fish's speed. Yūsuke uses a large fishing lure resembling Naruto to catch the marlin. The fish eventually gets exhausted from pulling on the lure and Yūsuke finally captures the marlin. Afterwards, Naruto notices a fūma shuriken on the marlin's forehead and pulls it out. The marlin returns home shortly after and the Konoha sail on a new boat, waving goodbye to Yūsuke.

While on the way to the Land of Lightning, Naruto and his bodyguards stop off at a nearby island, due to all his bodyguards becoming seasick, Guy in particular. While there, they see Sakura, Ino and Chōji picking up medicinal herbs on the orders of Tsunade and Naruto decides to help them, although he does not fare well, from eating poisonous herbs to being paralysed on a bridge. As Chōji spots one of the medicinal herbs, some ninja from the Benisu Island appear and make the Konoha ninja waste their time, while collecting the exact same herbs. However, they have a change of heart and give Sakura, Ino and Chōji all the herbs they picked up, as Naruto saved them from a monster protecting the Elixir Mud. With Guy feeling better, they head off towards the Land of Lightning and Tsunade's team back to Konoha happily, unaware that the Benisu ninja just gave them the herbs, so they could collect the debt owed after the war.

As they continue their voyage towards the Land of Lightning, Naruto, Aoba, Guy and Yamato sail through a thick fog. Yamato tells Aoba and Naruto about the "Ghost Ship" to pass the time. Suddenly, they met another ship, very much same to Yamato's description of the said ship. They come to the ship to investigate, and meet Hishaku, who is revealed to be a "soul" who cannot rest because of the guilt when the ship was attacked by the Giant Corpse Crab. Naruto and the others help him revenge the said crab, and later was revealed all his co-sailors and the captain cannot also rest. After defeating it, Naruto continued sailing, as well the ship set free.

While sailing to the Land of Lightning, Uzumaki Naruto and the others are attacked by pirates who wanted to sink their ship and loot the wreckage.

Thanks to some fast thinking on Yamato's part and the early warning by one of the sensor-type shinobi however, the ship is saved and they dock in an underground cavern. There they find a burial ground and a journal telling of the plight of the native islanders at the hand of the wicked Gataro and his men. Hearing this, Naruto vows revenge for the deceased and comes up with an ingenious strategy on how to escape the giant geyser that they were trapped in. Using Naruto's strategy the Konoha shinobi and crew were able to escape the island and put Gataro and his men out of commission.

While on their voyage to the Land of Lightning, a giant bird swoops down and kidnaps Guy. The team pursues the bird and are lead to a volcanic island. Upon arrival, Aoba spots a mysterious girl watching them and decides to pursue her while Yamato and Naruto search for Guy. During their search, Naruto and Yamato encounter many giant creatures, including the bird that kidnapped Guy. They eventually locate the bird's nest where they find Guy, who was actually kidnapped to babysit the bird's chicks. Meanwhile, as Aoba pursues the girl, he discoverers the animals on the island are actually bred to be used by shinobi as summons, as well as a research dedicated to developing the ultimate summon. He continues to follow her, and he is lead inside the volcano and finds a huge monster asleep inside an abandoned research lab. Using a mind reading technique, he discovers the monster was too powerful to be contained and had devoured many of the islands summons, as well as the researchers, before going to sleep.

The bird takes Yamato, Guy and Naruto to the volcano where they then encounter Aoba, and the beast suddenly awakens, going on a rampage. The monster is powerful and uses genjutsu as well as Lightning Release. Naruto has to enter Sage Mode while Yamato protects him as Guy and Aoba fight the beast in order to buy some time. Guy manages to knock the beast into the heart of the volcano, but the monster can also fly. The bird which kidnapped Guy comes down and attacks the monster along with the other summons. The girl, actually the spirit of the girl who the researchers used to restrain the beast until it grew too strong, appears and manages to immobilise the beast, with Naruto finishing it off with Wind Release: Rasenshuriken.

Rock Lee dreamed fighting Tobi, after awaking, he then thinks about his training to the upcoming war, and saw a boat, while Guy remembers their past "visualisation training" with him using the menu in a restaurant they celebrated when Lee mastered Reverse Lotus (although they left it in ruins when Lee was drunk). Guy wants to have it kept secret, he said it so they can remember what happened there (although he really knows what happened). First is training the White Crane Fist, but the birds beat them. Then the Snake Fist, but the quicksand almost killed them. Next is the Eagle Claw Fist, they had to climb on a seemingly-like cliff, but the eagle caught them. The last is then Lee getting near to know it, but Guy thinks of an alibi, but when they trained in a waterfall he then realises, and learned the Seasick Fist, which he then defeated Guy. Naruto then commented that he can't use said fist unless he didn't overcome his seasickness. Lee is later shown training it while riding in a boat.

The group stops for supplies and prepare to enter an area devoid of fish of the sea and wind that takes two weeks to be crossed. In the hold, a mushroom purchased by Naruto begins to multiply and to absorb the chakra of Yamato. After resisting for a long time without food, Naruto and Guy taste the mushrooms and it poisons them and push them to act in a violent manner. Without alternatives, Naruto calls Gamatatsu and asks him to bring him Shima's food, composed of insects. All aboard eat and regain strength, even managing to defeat the bandits who sold them the mushroom when they come to look for valuable cargo.

After having braved a storm, four of Naruto's shadow clones rebel against him, taking him hostage, forcing the crew to stop in an island. Naruto's clones were going to kill him, but he wakes up and realises it was all just a dream of one of his clones. So, when the clone was extinguished, his memories was transferred to the real Naruto. Naruto becomes respectful of his clones and releases the technique, giving the clones the rest they craved and deserved.

Shikamaru begins to feel the pressure of shouldering the lives of his friends in the upcoming Fourth Shinobi World War. To help ease his mind, Shikaku sends his son along with Tenten on a mission to Mokuzu Island to replenish supplies. On the island, Shikamaru meets up with Naruto's group. Soon after they set sail, the fog around the area gets thicker and they encounter reef systems, a huge rock and a whirlpools again and again. Shikamaru figures that their ship is sailing through the bay in circles and tells Naruto and the others to sail straight for it and get swallowed up. The criminal, on seeing the ship wrecked, arrives at the spot with his gang to loot the wreckage. Having stored the ship in Tenten's scroll, they proceed to defeat the criminals.

While crossing part of their trajectory by land in the Land of Water's territory, Naruto's group comes across an imposter, claiming to be him. He and his partner are acting as criminal and hero duo, claiming to defeat Naruto, who had apparently become famous due to his victory over Pain, in order to build up a reputation for themselves during the upcoming war. Naruto however quickly defeats him. Mercenary ninja attack the imposter Naruto, thinking him to be a missing-nin, in order to collect a reward. Iggy calls Naruto's group for help, but they need to be on their way to the Land of Lightning. Iggy tries defending Banna on his own. Having stayed behind to see what he'd do, Naruto's group helps defeating the mercenary ninja and continue on their way.

Kokuyō wants Shizuka to be his wife in order to control her village, which she repeatedly spurns his advances. Tokiwa, her attendant saw Naruto and after being told that he was Jiraiya's student told him he had to battle Shizuka for his hand in marriage as Jiraiya had promised Shizuka's mentor. He declined the offer, but however Tokiwa tracked him down, and narrated Shizuka's past to him, as she also was against the village's law that female should marry the man who defeats them in battle, and accept the duel. He fooled Aoba, Guy and Yamato to buy some time. He defeats Shizuka, but Kokuyō attacked Shizuka again, only to be defeated by Naruto's Rasengan. Naruto talks to Shizuka about his unrequited love for Haruno Sakura. He then encourage Shizuka to rethink her destiny.

After Rock Lee falls into a river during their training, Tenten has a flashback of her youth, while waiting for him to surface. When she was a child, she had dreamed to become a strong kunoichi like her heroine: Tsunade, and thanks to Guy's guidance she initially began her path towards becoming a legendary medical-nin. However she failed during her training trying to heal a fish, and her attempts to sign a contract to summon a creature like Tsunade's famed slugs met no success because of her quarrel with Ningame, Guy's summon. After many failures, Guy notes that she had a talent for fūinjutsu and began honing her unique fighting style. After that she realised that she was a weapons specialist and vowed that instead of becoming just like Tsunade, she would still become a legendary kunoichi.

In Konohagakure, Kakashi while meeting with Tsunade about the impending war, receives an emergency messenger tortoise from Guy with an SOS message, so he heads out to find out what has happened. On board the ship, Guy recalls the time when he and Kakashi first became rivals and their numerous battles since then. Later on in the night, the jōnin meet where Yamato tells them about a rumour of a shinobi capable of not only copying someone's appearance, but also their chakra. Kakashi soon arrives at the ship, and calls for Guy. Unaware that he sent an SOS message, Guy comes to the conclusion that the one before him could be one of those imposters that Yamato spoke of. With this notion Guy proceeds to attack Kakashi and later Aoba and Yamato when they side with Kakashi. After giving Guy irrefutable proof that he was who he said he was by telling him something from their youth, Kakashi returns to Konoha upon learning that the SOS tortoise was sent by accident.

While on his way to meet messengers from Iwagakure, Chōjūrō decides to go on ahead by himself, due to the slow progress in travelling. Naruto and his group stop in an island for restocking before going straight to the Land of Lightning. Naruto sets off to eat. Akatsuchi is sent by the Tsuchikage to the same isolated island in the Land of Water to rendezvous with Chōjūrō, and Kurotsuchi tags along. As they await, they're attacked by a group of Kirigakure ninja, led by Ganryū. Battle ensues and Akatsuchi is injured. Naruto and Chōjūrō interfere and stop the battle. Chōjūrō demands Ganryū and his team to withdraw, stating that they are violating the Mizukage's will. The team leaves, and Kurotsuchi argues with Chōjūro to tend Akatsuchi's injuries, who says they need to wait for a medical-nin. Chōjūrō explains those were ninja who oppose the Allied Shinobi Forces, Ganryū being the sole survivor of the Tragedy of Yosuga Pass.

Kurotsuchi heads out to kill Ganryū before he can kill her. Naruto stops Kurotsuchi and Ganryū from killing one another, also telling Ganryū that it will just create a cycle of hatred. Kurotsuchi attempts to slash Ganryū using her sword, but Naruto blocks it with his body. Ganryū agrees to let Naruto fulfil the peace. Chōjūro arrives with other Kiri ninja, telling Ganryū to surrender, which he does. Chōjūro informs him that the Iwa messenger was sent by the Tsuchikage himself, to formally apologise for the Tragedy of Yogusa Pass, and return a personal belonging of one of Ganryū's team-mates who was killed in it. Chōjūro tells the others that Ganryū won't be sentenced for execution. Akatsuchi then tells Kurotsuchi that Kiri will just owe Iwa a favour in the future to come, delighted that the Iwa-Kiri grudge has come to an end. Naruto leaves in a hurry, without introducing himself to the others. Once arriving with Yamato and the others, they await for a new ship to take them to the island in the Land of Lightning.

Confining the Jinchuriki arc
The group eventually made it to their destination in the Land of Lightning. Once Guy recovered from his seasickness, he asked Motoi to help them locate Naruto. Motoi took him and Aoba to the Falls of Truth, explaining that Naruto began his training to conquer the Nine-Tails by sparring with his inner-self. Interested in going through the same training, Guy approached the falls. As his "true-self" began to manifest it mocked his ideology of youthfulness, saying that "Old men shouldn't push themselves so hard". What finally emerges was apparently a blowfish, but in reality Kisame Hoshigaki. Guy immediately attacked him, knocking him into the falls.

Guy once again could not remember meeting Kisame before. He nevertheless recognised that Kisame was a threat and pursued him as he tried to escape the island. He first had Killer B fling him across the island, and then summoned Ningame mid-flight to provide him a stepping stone. He found Kisame trying to send intel he had gathered to Akatsuki by way of shark. To mask the shark's movement, Kisame created a thousand more, which Guy attempted to stop with the Morning Peacock. When he was unable to stop all of the sharks, Guy was forced to open the Seventh Gate: Gate of Wonder in order to match Kisame's Water Release: Great Shark Bullet Technique with his Daytime Tiger. When the two massive techniques clash, Guy's Daytime Tiger went right through the Great Shark Missile and hit Kisame dead on, erupting into a massive shock wave large and powerful enough to have its after effects be felt some distance away.

The Konoha ninja restrained Kisame and tried to gather intel about Akatsuki from him, but he broke free of his bindings and committed suicide to prevent them from interrogating him. Seeing how far Kisame was willing to go for his comrades, Guy gained new respect for his adversary and vowed to always remember him. Hoping that the intel Kisame had would reveal something they examined it, only to be caught in water prisons with sharks. Guy, finally experiencing the side-effects from the seventh gate, was unable to defend himself, but was saved by the others.

Fourth Shinobi War arc
When the Fourth Shinobi World War began, Guy was placed in the Third Division under Kakashi's command. Still suffering from the effects of opening the Seventh Gate, Sakura healed him as a concerned Lee looked on. He recovered by the time the Third Division comes to the aid of the Surprise Attack Division, restraining Gari when they first arrived.

When fighting broke out with Akatsuki's reincarnated ninja, Guy teamed up with Lee to defend members of the division from Haku. Prior to returning to the fight, Guy reminded the troops not to lose their resolve when friends die but to turn their death into the life of another. In the anime, after the Seven Ninja Swordsmen of the Mist were summoned, Guy told Lee to chase after Pakura, while he went after Gari. Guy later regrouped with the rest of his division to recuperate in a forest, as night fell.

In the anime, as the battle resumes the next day, Guy aid Kakashi in battle with Kushimaru Kuriarare and Jinpachi Munashi. Later, he informed Kakashi,after Fuguki Suikazan was sealed, that there were only three reincarnated shinobi left on the battlefield. Upon seeing the new wave of White Zetsu Army forces approaching them, Guy told Kakashi that they should defeat them in one fell swoop while at the same time, Naruto's shadow clone appeared on the battlefield to aid them.

Later, Guy's division was attacked by a famous reincarnated taijutsu master named Chen. Exciting at the idea of facing the legendary hero, Guy formally challenged the reincarnated shinobi to battle. The two taijutsu masters initially fought evenly, but Chen's tireless reincarnated body soon overwhelmed Guy. When Rock arrived to aid Guy, both Lee and Chen were surprised to see each other. After hearing the story of how Chen and Lee met, Guy was outraged to hear Chen tried to make Lee quit being a shinobi. While he admitted that Chen's views weren't wrong, it was still Lee's own personal dream. Feeling he had to prove his point once and for all, Chen attacked the teacher and pupil with his Leaf Dragon God. To Chen's surprise, Lee revealed to have learned the weakness of Chen's technique and defeated it. Amazed at how far Lee came solely with taijutsu and the bond that he had with Guy as a teacher, Chen admitted to his own faults with his student, ashamed to have not had more faith in him. Finally letting go of his past pain, Chen broke the summoning contract and returned to the afterlife.

After sealing the final Swordsman, Guy and Kakashi made their way to Naruto and B's battlefield in time to stop Tobi from warping Naruto away. Guy uses his Violent — Leaf Adamantine-Strength Whirlwind technique to force Tobi to become intangible while Kakashi retrieved Naruto. After being talked down to, Guy told Tobi not to underestimate him as he was Konoha's Sublime Green Beast of Prey. He then told Naruto to calm down as his explanation of the situation was jumbled, before destroying the coral covering Naruto's body. As the tailed beasts attacked again, Guy told Kakashi that he wasn't good with faces, and they all looked the same to him before opening the Sixth Gate as he, and Kakashi begin their counter-attack. As Kakashi wondered why the reincarnated opposition weren't using the regular abilities of the Six Paths of Pain, Guy stated that Tobi would most likely know that they had come up with counter measures against these abilities, so he wouldn't waste his time and chakra, having them use it.

As their battle with the tailed beasts continued, Guy noticed Naruto in the clutches of Son Gokū's mouth. Alerting Kakashi before springing into action, he was impeded by the the Six-Tails' corrosive gas bearing down on them at one end, and the tailed beast barricading them at the other. Turning back-to-back as Kakashi creates a shadow clone in the Manji Formation, the men entrust their backs to each other as they face the enemy in front of them. As Guy rushed towards the gas he uses the Morning Peacock technique to burn off the gaseous attack and prepared for the next wave of attacks. As Naruto succeeded in releasing Son from Tobi's control, both Kakashi and Guy look on, shocked, as the now fully-transformed jinchūriki bore down on them.

As the situation became dire, Guy stated that there was no option but for him to use the Eighth Gate after telling Kakashi that there was no way he would have enough strength to warp away the five Tailed Beast Balls that were aimed at them, but Kakashi also dismissed Guy's suggestion, stating he would die after opening that gate. Both men are rescued, however, by Naruto, entering a new mode and deflecting the attacks. Absorbed into the Nine-Tails' chakra as Naruto transformed, both men watch on as the battle between the beasts ensued. Guy later noted that it looked like a scene from the Destroy All Monsters film.

After Naruto's Tailed Beast Mode is cancelled, and the men stand alongside Naruto, facing the opposition, Guy stated that seeing Naruto come so far made him feel old. Somewhat shocked, Kakashi was the one to tell him that their youth wasn't over yet. Guy then stopped Kakashi mid-sentence, saying that he was making him feel even older. He later mobilised alongside Kakashi, Naruto, and B in his full Eight-Tails form preparing to assault Tobi and the Demonic Statue of the Outer Path. Launching his assault after Kakashi and his shadow clone attacked the statue once again, Guy used his Little Toe Attack to crush the statue's foot sending it toppling over and straight into Naruto and B's uppercut attack all the while cheering Naruto on as he mocked Tobi against Kakashi's advisement.

Guy later noted that the statue had been acting weird ever since it swallowed the two objects in its mouth. After Naruto and Kurama switched in order for the beast to explain what was happening, Guy listened on before asking what the Treasured Tools of the Sage of the Six Paths and the Gold and Silver Brothers had to do with the current situation. After he heard Tobi chide Kakashi, telling him that he spoke too easily which was why he lived a life full of so much regret, Guy asked him who exactly he was but Tobi only responded stating that it wouldn't make any difference because Guy didn't remember faces. When Naruto retorted that dreams were essential, Guy added that even if you never want your youth to end, people had to stop dreaming some time or the other.

As the team prepared to attack Tobi directly, Guy noted that the use of feints would be crucial in this battle because of Tobi's abilities. Deciding that it was better to not attack him directly, Guy reaches into his pouch and retrieved his Sōshūga. Providing Naruto with backup, Guy was able to intercept one of Tobi's attacks which forced him to become intangible. Deflecting all of Tobi's attacks Guy was ultimately able to knock the masked man off his feet and send him hurling towards Naruto's Super Mini-Tailed Beast Ball. Shocked when Tobi disappeared, Guy tried to reach Naruto when the masked man reappeared but noted that the falling debris was becoming cumbersome. Later regrouping with his comrades, Guy asked them if they were okay before they wondered how they could defeat Tobi.

Noticing the small crack in Tobi's mask, Guy alerted Kakashi to the occurrence. Assuming that the crack was as a result of Naruto's last attack, Guy noted this but Kakashi disagreed noting that the crack wasn't concurrent with a punch. Obliging Kakashi's request to test out his hypothesis, Guy climbed aboard Gyūki's hand and is then launched across the battlefield towards Tobi. Confronting the masked man first, Guy uses his Sōshūga them to break the rock in front of him forcing Tobi to phase through them. Using the nunchaku Guy attacks the intangible masked man, provoking Tobi to become intangible and absorb them and as such, susceptible to Naruto's incoming attack. Guy later listened in shock as Kakashi revealed the mechanisms behind Tobi's technique.

Telling Kakashi to explain it as simply as possible and based off this, they would readjust their strategy, Guy and the others listened as Kakashi explained the mechanism behind Tobi's warping ability and intangibility. When B questioned why Kakashi's Sharingan was connected to Tobi's dimension, Guy hesitantly turns to Kakashi who questioned Tobi on where he got the eye. Shocked by the answer, Guy is later visibly angered when Tobi chastised Kakashi and shocked once again when Kurama spoke directly to Tobi before Naruto charged at the masked man in his Tailed Beast Mode. Shocked to see Naruto heading out on his own, Guy alerted Kakashi whom he soon realised was lost in deep thought. As he tried to get his comrade to focus, the two watch on as Naruto and B confronted the mask man. When Kakashi finally came around the two men charge at Tobi, with Guy remaining by Kakashi's side as he put his new strategy into action.

Alongside Kakashi, Guy who was supporting the latter after he had collapsed, was left completely stunned upon seeing that Tobi is Obito Uchiha. As a shocked Guy and Kakashi question the once masked man, their questions are greeted with indirect answers. Later when Obito attacks Guy and Kakashi, Guys calls out to his comrade who was seemingly frozen in shock. They are later further surprised by the arrival of Madara Uchiha to the battlefield. As the battle waged on, Guy aided Naruto in fighting the legendary Uchiha, and though bloodied and seemingly exhausted, he noted to Gyūki and B that it was because Madara was so strong that made it worth fighting him, which prompts the Eight-Tails to tell him that he should not push himself so hard. As the battle waged on, Guy realised that the Wood Dragon was absorbing Naruto's chakra, but before they could lend their aid, he and the Eight-Tails were bound by Madara and rendered immobile. As Madara was about to deal the finishing blow the attack was intercepted by Naruto. Hearing Naruto's speech to protect his comrades then spurred Guy on to use the Daytime Tiger to attack Madara, which sends the Uchiha flying away from them, prompting the Eight-Tails to acknowledge that Guy wasn't just acting tough.

When Kakashi noted that he had resolved to protect Naruto, Guy echoed his sentiments, and when the Wood Release had loosened its hold on Gyūki who was able to break itself and Guy free. As the process is completed and the Ten-Tails is resurrected, Kurama places Guy and Kakashi into his mouth, from which he restores the two shinobi's respective chakra. After Kurama is forced to retreat momentarily to gather more chakra, the remainder of the Allied Shinobi Forces arrive to their comrade's aid in time to deflect a point blank Tailed Beast Ball fired at their comrades. When Shizune arrived, she immediately began healing Guy who later stood with the rest of the Alliance, prepared to face the opposition.

Opening the Fifth Gate, Guy and his student prepare to attack the two Uchiha but are buffeted by the force exerted by the now fully-matured Ten-Tails as it escaped the hole it had seemingly been trapped in. Arriving to where Neji's corpse was, Guy tells a weeping Lee not to cry and that if they remembered Neji and his feelings, then he would live on inside them forever. This is later affirmed by Kakashi and Naruto, despite Obito's attempt to decry that sentiment. After receiving chakra from Naruto, Guy and the other shinobi charged towards the Ten-Tails. Launching Lee towards Madara, their combined effort was enough to sever the Uchiha's connection to the beast and forced them to retreat to the ground.

Later as he saw the Four Red Yang Formation erected around the Ten-Tails, Guy informed Lee that the technique was no easy feat and that only shinobi of Kage-calibre were able to erect such a powerful barrier reputed to be stronger than even the Four Violet Flames Formation. With the situation later turning grim as the Alliance was trapped in a barrier with a Tailed Beast Ball-firing tree, Guy and the other shinobi soon found themselves shrouded in the previous Version 1 mantles again. He and the other subsequently found themselves on the outside of the barrier, escaping the near-fatal attack thanks to Naruto and Minato's action.

Naruto Shippuuden movie llllll
The movie starts with a flashback of the Nine-Tails' Attack on Konoha, which then flashes forward to the present timeline where the eight members of Akatsuki who are meant to be dead, are actually alive and are battling the Konoha shinobi and this in-turn unsettles Sakura. Shikamaru states there is no point in wondering why the dead are back alive and quickly comes up with a counter plan, but Naruto quickly attacks Akatsuki head on, forcing the rest of the Konoha 11 plus Sai, Kakashi and Guy to attack. The battle continues until Naruto is caught by Kakuzu, Sai frees Naruto by cutting part of Kakuzu's arm off, causing the Akatsuki to retreat. Naruto and his friends return home, where most of Naruto's peers are congratulated by their families, all of whom promise to write a recommendation letter for the promotion to becoming a jōnin although Sakura has a little fight with her family who embarrass her in front of the others. As Naruto returns home, he passes many families causing him to reminisce of his father and mother causing him to feel lonely. Later while eating at the Ichiraku Ramen, he meets Iruka. He then asks Iruka for a letter of recommendation of his own, but Iruka refuses as Naruto is only a genin and must become a chūnin and rise through the ranks just as Minato and all other jōnin did. Naruto is saddened by his lonely lifestyle and so storms off saying that no one seems to understand him, and also that he doesn't like the extra menma on his ramen (which adds to his present state of mind and causes him to feel lonely). He meets Sakura, who had an argument with her family and also stormed out, grabbing Naruto's hand and telling him to go on a date with her. While Sakura complains about her family, Tobi appears in front of them and after a small scuffle, he then activates the limited Tsukuyomi. Naruto and Sakura are absorbed in a flash of light, and later find themselves still in the same park they were before with no signs of a fight or Tobi himself.

They run into their friends including Sasuke, which surprises both Sakura and Naruto, but with different personalities, and to add to the confusion, no one knows who Tobi is. They realise they are in another world where Sakura's father was the Fourth Hokage, who saved the village instead of Minato, and in this world Naruto is named Menma instead. As Naruto and Sakura return home Sakura is happy for the new freedom she has, while Naruto hurries home to his apartment hoping to see his parents, only to find he does not live there.

Meanwhile, in the present, Tobi reveals that the dead Akatsuki members in the beginning were only Zetsu clones. In the Genjutsu World, a man in a mask meets Tobi and they agree to work together. Elsewhere, as Sakura is looking through her dresser, she sees the Fourth Hokage coat that Naruto's father once wore in the present causing her to once again realise that in this world, it was her father who was the hokage. She then meets Sasuke who gives her a flower and flirts with her. Naruto and Sakura meet in the morning to try to gather more information of their current world, although Sakura enjoys this world as she has more freedom and is well loved by the village thanks to her father's actions. Naruto, on the other hand, wants to return home as fast as possible.

Naruto and Sakura meet Tsunade and Shizune, who tell them that a masked man attacked Kumogakure, and killed their jinchūriki which Naruto and Sakura believe to have been Tobi. They then meet Naruto's parents, who are alive in this world. Minato says that Jiraiya died finding the Red Moon Scroll that was said to help save the world. Tsunade lets Naruto and Sakura join Minato and Kushina on their mission when Kakashi and Guy return. Sakura is shocked at finding out who Naruto's parents are, while Naruto is angry that Tobi would dare to make copies of his dead parents, and he swears to break the Genjutsu. While Sakura is still enjoying her life, she wonders how Naruto is doing. While Naruto attempts to ignore his parents, he sees an album showing him how his life would have been if his parents had been alive.

In the morning, Sakura notes that this world's Kakashi and Guy have switched personalities, while Naruto isolates himself from his parents at every turn. They soon locate where Jiraiya hid the scroll, but as the group stops to rest, Naruto charges ahead until he is confronted by the appearance of Gamabunta, Gamahiro and Gamaken. They refuse to listen to Naruto and the group who explains their reason for being there and attacks them with an army of frogs. Naruto attempts to enter Sage Mode, but while trying to gather enough energy, Kushina interferes and tries to protect him from Gamabunta but a shot of acid burns her leg. As a result, Naruto gets distracted and is unable to enter sage mode. Minato then saves both of them quickly and is able to get the scroll, dispelling the Summoning Technique.

As Sakura heals Kushina, Naruto still attempts to brush off his parents, causing Minato to say no matter what Naruto does, they will always try to save him as that's what they naturally tend to do as parents. Kushina then awakens and hugs Naruto, causing him to breakdown in tears and finally accept them as his parents. They return to Konoha, where Tsunade locks the scroll in the village's safe until the night when a red moon will appear, when they can use the scroll to fulfil the said prophecy. As Naruto and Sakura walk home together, Naruto quickly runs home saying he has something to do, leaving Sakura alone. Sakura now finds her home too lonely and wonders if Naruto's always felt this way. As she walks down town she sees happy families, only making her more sad. She then realises that this world's Sasuke is just a flirt as she sees him flirting with a group of girls and decides that Naruto was right on his decision to quickly break the genjutsu they're now trapped in and wishes to return to their own world. As she walks to Naruto's home to try to find a way to break the genjutsu, she see how happy Naruto is and wonders if they really should leave. Sakura later meets Naruto, and asks him if he wants to stay. Although he denies it, he later thinks to himself that he truly does not want to leave.

At that moment an explosion occurs at the Hokage's office, where the masked man from earlier asks for the scroll they brought back. He overpowers Minato, Kushina, and Tsunade, and then Naruto and Sakura arrive. They realise that this was the man Tsunade was talking about, and that he knows Tobi. He overpowers Naruto and Sakura, and kidnaps Sakura in exchange for the scroll. He then uses Great Spiralling Ring, destroying a large part of Konoha and leaves. Naruto tries to save Sakura, but Minato prevents him, showing that in the end this world's Minato is different from his father. He takes one of Minato's kunai and the scroll leaving with Sakura's father's Hokage coat. Sakura is tied up and meets Tobi who is a ghost saying they are in an old training ground that Minato and Jiraiya used. Naruto arrives but is attacked by the other masked man asking for the scroll. Naruto is unable to fight properly as his stomach acts up, the Masked Man then takes the time to summon the Nine Masked Beasts, and about to kill Naruto when the Akatsuki arrives and saved him.

This Akatsuki was hired by Tsunade to help Naruto, and they deal with the masked beasts when Naruto attacks the masked man. Itachi saves Sakura and Tobi decides to escape instead. The Akatsuki defeats the masked beasts that turn into nine fox kits, while Naruto chased the masked man into the training grounds. They then fight, Naruto uses Sage Mode and uses the Wind Release: Rasenshuriken to counter the Masked Man's Great Spiralling Ring. It ends in a draw, but the attack destroy the masked man's mask, showing that he is Menma, this world's Naruto. Menma informs Naruto that the pulsating inside his stomach must be Kurama's reaction to the Black Nine-Tails within Menma. Menma then called back the defeated masked beasts, and summoned Kurama's counterpart, the Black Nine-Tails. Naruto was unable to attack, while the Akatsuki retreat, taking Sakura with them. Not wanting to be manipulated by the Sharingan again, Kurama makes a truce with Naruto to work together, allowing him to summon Kurama out of his body. In the battle Naruto is barely able to win, but Tobi reveals that this was his plan, to have Naruto and Menma fight, as doing so would cause the two foxes to fight and weaken Kurama. As he possessed Menma, Kurama warned Naruto if he looked into Menma's Sharingan, it would be all over, for Tobi planned to extract Kurama out of Naruto the same way he extracted it from Kushina sixteen years ago. As Menma overpowers Naruto, the latter tries to use the scroll when he notices the moon had turned red, but Menma cuts the scroll, causing Naruto to look into Menma's eyes. Naruto's memories are erased, but Sakura rescues him before Kurama is extracted from him.

Naruto, in an amnesiac stupor, stares at the destroyed Red Moon Scroll, which brings back memories of his training to learn the Rasengan with Jiraiya, and how his father was the one who invented the technique. Naruto is able to break free of the genjutsu just in time to save Sakura, and then defeats Tobi the same way his father did, breaking the Limited Tsukuyomi. Tobi, using his ghost body, attacks again, until Minato and Kushina arrive. Tobi decides to give up and exits the genjutsu world just as Naruto and Sakura are enveloped in a bright light, preparing to return to their world as well, but beforehand Naruto thanks Minato and Kushina who quickly goes to assist Menma who is returning to his original state as their son. Naruto and Sakura returns to their world, where Naruto's Hokage coat breaks down since it was only part of the genjutsu world and not real. Naruto and Sakura tell Tsunade and Kakashi of what transpired and sets out more guard patrol since Tobi was easily able to enter further in the village than they imagined. Shizune also brings up the topic of the letters of recommendation from the beginning of the movie, to which Tsunade replies that she has no intention of promoting any of Naruto's friends to jōnin. As they both return home, Naruto watches Sakura as she meets her parents, happily hugging them. He approaches her, asking her out on a date, but Sakura tells him they just came back from the longest date ever, much to Naruto's shock. As Naruto goes home, he sees Iruka in his house, waiting to apologise to him. Afterwards, Naruto happily jumps roof top to roof top through the village while quoting that the road of a ninja is one who endures.

Quotes

 * (To Lee) "Yes!! This is what youth is all about!"
 * (To Lee) "It's true that you're different from Neji… You're not a genius in ninjutsu nor genjutsu, not even taijutsu… But you know what Lee? You are a genius that has the strength and potential within himself to surpass Neji… …Because you are… a genius of hard work."
 * (To Lee) "For those who don't believe in themselves… hard work is worthless!! …You are very much like me, Lee. I used to be a loser too. But these days I can even win against the elite genius Kakashi."I want to prove that even without ninjutsu and genjutsu I can become a great ninja" that's your nindo right? That's a great goal, it's worth working hard for!"
 * "No, now the tables will turn. The lotus of Konoha blooms twice!"
 * (To Kakashi) "What would you know about that boy? That kid has a precious thing he would give up his life to prove. So I wanted to turn him into a man that could accomplish it… That is all…"
 * (To Gaara after saving Lee) "He is my beloved comrade."
 * (To Lee) "You worked hard Lee, there's no doubt in my mind the surgery will be a success. You have the power to shape your own destiny. And on the one-in-one thousand, no, one in a million chance something to happen to go wrong, I will die right along with you. Since the day I met you, my nindō has been to train you to become the most splendid ninja possible. That's a promise!"

Trivia

 * In the Shonen Jump magazine, Viz rendered Guy's name as "Mighty Guy" in some of the earlier chapters; this was changed back to "Maito Gai" in most of the graphic novel stories, and later changed to "Might Guy" when the guidebooks were released.
 * The name "Might Guy" is a joke aimed at the "hot-headed hero" archetype that appears in many movies and anime.
 * Guy's appearance and mannerisms seem to be based off those of Bruce Lee. He even wields nunchaku and wears a jumpsuit.
 * As of chapter 595, Guy has had all four of the compass point animals in Feng Shui associated with him: Morning Peacock being the Vermilion Bird, the Afternoon Tiger being the White Tiger, The Turtle as his summon and the Dragon being the basis of the design of his Nunchaku.
 * According to the databook(s):
 * Guy's hobbies are repeated side-steps, and hitting focus mitts.
 * Guy wishes for a rematch with Kakashi.
 * Guy's favourite foods are super-spicy curry rice and curry udon, though he finds it impossible to dislike food.
 * Guy's favourite phrase is "Overflowing youth!!" (とび出せ青春!!, Tobidase seishun!!).
 * Guy has completed 788 official missions in total: 86 D-rank, 270 C-rank, 210 B-rank, 199 A-rank, 23 S-rank.
 * Strangely, even though aoi could mean green or blue, most current Viz subs and dubs refer to Guy as the "Blue Beast" rather than "Green Beast".
 * In Naruto: Ultimate Ninja Heroes, Guy calls himself "Beautiful Savage of the Leaf Village".
