Here be spoilers. Any thing that has not been aired on the free versionnote of Crunchyroll should be spoiler-tagged.
Pre-Leaf Village Senju Clan
The brother of Hashirama, Tobirama, and Kawarama Senju.
- Child Soldiers: He was a young boy fighting in an eternal war.
- Cynicism Catalyst: His death caused Tobirama to become jaded and cynical.
- Doomed by Canon: Despite many chapters devoted to backstory, a third Senju bro was never mentioned. Predictably, he dies in the chapter he first appears in.
- Mauve Shirt: Has a bit of characterization before biting the dust. But not much.
- Multicolored Hair: One side white, the other side black.
- No Kill Like Over Kill: How he died, cornered and slaughtered by five adults.
- Posthumous Character: Been dead since long before the story began.
- Small Role, Big Impact: You know all the other guys who supposedly triggered the plot of Naruto? Well, as long as the flashbacks go further back in time, we keep getting earlier and earlier causes for the plot. At one point before Black Zetsu was revealed as The Chessmaster it was Itama who triggered the plot. His death caused Tobirama to become jaded, which caused him to kill Izuna, which caused Madara to go crazy, which caused him to do a bunch of evil stuff and make Obito into his evil successor.
- We Hardly Knew Ye: Died in a flashback without getting any real characterization.
The brother of Tobirama, Hashirama, and Itama Senju. Died a pointless death in the war. His arm was sent back to his family.
- An Arm and a Leg: Subverted. After he died, his family didn't receive his body, they received his arm.
- Child Soldiers: He was a young boy forced to fight in a seemingly never-ending war. A more extreme case than usual for this manga in that he was seven when he died.
- Cynicism Catalyst: Surprisingly averted. Unlike how Itama's death was for Tobirama and how Izuna's death was for Madara, Kawarama's death makes Hashirama acknowledge that the world they live in is a terrible one and wishes to change the world for the better.
- Doomed by Canon: See the above example.
- Killed Offscreen: His death is never seen. That's probably for the best.
- No Kill Like Overkill: Let's reiterate - He was a seven-year-old fighting in a war and all that was left of him was his arm.
- Scars Are Forever: He had an x-shaped scar.
- We Hardly Knew Ye: We didn't even meet him, in fact...
The father of Hashirama, Tobirama, Kawarama, and Itama Senju. Leader of the Senju Clan in the past.
- Abusive Parents: He hit his son for suggesting that another son had died a pointless death.
- Arch-Enemy: There was no one he hated more than Tajima Uchiha.
- Blade Across The Shoulder: Theres a strap on his left armor shoulder that carries a tanto.
- Blue-and-Orange Morality: Believes that turning his sons into emotionless killing machines, to be sent off and die in war is the greatest form of love a parent can show.
- Family Honor: A firm believer in this.
- Jerk with a Heart of Gold: Whilst abusive, he does love his children, and would falter in battle if he saw one of them die.
- The Leader: He led the Senju Clan in the past.
- Meaningful Name: The first character used in writing his given name is also used to write that of Buddha.
- Not So Different: Hashirama accuses him of not being so different from the Uchiha in his willingness to go to war regardless of the consequences to his family. Worse yet, he and Tajima Uchiha both aim for each other's children in order to cause the other to hesitate.
- Outliving One's Offspring: The only exceptions being Hashirama and Tobirama.
- Sunk Cost Fallacy: Believed in this.
- Would Hurt a Child: Not just hurt, but kill.
Land of Waves Arc
Voiced by: Naoki Bando (JP), Fred Tatasciore (EN), Humberto Sorlózano (LA Spanish)
The founder of Gato Shipping and Transport. A multi-billionaire who is said to be the richest man in the world. However, he makes most of his money with his shady business deals. Gato is the first major villain to appear in the series.
- Anime Hair: He has an utterly crazy hairstyle.
- Arc Villain: Gato is the central antagonist of the Land of Waves arc, but he is of no importance to the overarching story and is just there to be the first villain.
- Asshole Victim: Though he's not seen too much, he does make himself to be a Jerkass. So when he finally gets killed by Zabuza for all the things he's done to the latter, along with the the things he did to the village, it's likely no one sheds any tears for him.
- Bullying a Dragon: He subjects the ninja he hires to much abuse because he thinks the money he offers them will keep them in check.
- Corrupt Corporate Executive: He's an evil businessman.
- Chronic Backstabbing Disorder: Frequently hires top dollar assassins to take people out for him, then uses mobs of grunts to take those assassins out so he doesn't have to pay them.
- The Dog Bites Back: Suffers from this when his constant mistreatment of Zabuza comes back to bite him big time. After he tells the latter You Have Outlived Your Usefulness, he then kicks Haku's face as payback for breaking his arm earlier, and then seems a little upset that Haku was dead by that point.
- Evil Old Folks: He's fairly old, and also a monster who kills people to make money.
- Greed: He is willing to assassinate people and force whole countries into poverty just to make more money.
- Idiot Ball: Though he is pretty ruthless, for some reason he never has his henchmen harass the workers building the bridge, nor does he attempt to have it blown up to destroy it. Instead he's solely focused on taking out Tazuna. It's not likely that anyone would have had the power to stop him prior to Naruto and company arriving, considering how downbeat they were after Kaiza's death.
- Ink-Suit Actor: Unintentional, but he does look like his voice actor in the English dub, Fred Tatasciore.
- Karmic Death: In the backstory of the Land of Waves arc, he chopped off both of Kaiza's arms and then killed him. At the end of the arc, he is killed by Zabuza, who is unable to use his arms.
- Kick the Dog: His execution of Kaiza is there just to show that he's a bad guy. He later kicks Haku's corpse just to further hammer in how much of a complete scumbag he is.
- Non-Action Big Bad: He's the villain of the Land of Waves arc, but his power comes from his money, not his physical strength. When he does enter the final battle, Zabuza kills him with one blow.
- Off with His Head!: Zabuza kills him by chopping off his head in the manga, slitting his throat in the anime.
- Smug Snake: Acts completely full of himself.
- Starter Villain: He's the first major antagonist that Team 7 faces in the story.
- Stupid Evil: Some fanfics point out his stupidity for bleeding Wave dry. It's an island country with easy access to almost half the continent. He's a shipping magnate. With a little Pragmatic Villainy, imagination and money, he could have made the country incredibly prosperous, made himself richer, and gained a boatload of good will.
- White Hair, Black Heart: His hair is white, but make no mistake, he's an evil bastard.
- You Have Failed Me: Subverted. He is constantly angered when his assassins fail to kill Tazuna, but while he does show up to kill Zabuza, he was going to do that anyway.

A famed bridge builder. He's working on a bridge that will connect the Land of Waves to the mainland. However, he is threatened by Gato, a businessman who wants to stop him so that he can make money by holding a monopoly over the shipping and transport industry in the Land of Waves. Tazuna decides to hire a group of ninjas to defend him.
- Assassin Outclassin': It is only thanks to his bodyguards, particularly Kakashi and Naruto, that Tazuna narrowly avoids getting killed by Zabuza Momochi.
- The Bus Came Back: He and Inari briefly reappear after the Pain arc to help Konoha.
- Cool Old Guy: Though he's not a fighter in the sense of the ninjas, he still defiantly builds the bridge despite the threats against him by Gato. Considering Gato killed his son-in-law Taizo as an example of what happens to people who defy him, it took a lot of courage for him to continue working on it.
- I Have a Family: After he is revealed to be targeted by Gato, he brings up his grandson and daughter to goad the ninja into continuing their protection.
- Jerk with a Heart of Gold: He may pick on Naruto and lie about missions, but he's a genuinely good guy just trying to help his country.
- Manipulative Bastard: After his deception is revealed, he has no qualms using the thought of his family mourning his death to emotionally manipulate Team 7 into protecting him.
- Poor Communication Kills: Justified and lampshaded. Kakashi says that by lying about the nature of the mission he gave them, he risked the lives of the whole team. Tazuna responds by pointing out that he had to say it was a "C" rank mission, because the Land of Waves was so poverty-stricken that he couldn't afford to pay the "A" rank fee.
Voiced by: Misa Watanabe (JP), Cindy Robinson (EN), Diana Pérez (LA Spanish)
Tazuna's daughter, who lives with him.
- Berserk Button: She gets mad when Tazuna mentions Kaiza in front of Inari, because she knows how much it upsets her son.
- Stepford Smiler: She's pretty broken, what with losing her husband, then losing Kaiza. However, she tries to remain cheerful.
- Stop, or I Shoot Myself!: She treats to kill herself by biting off her tongue if her hostage-takers hurt Inari.
- The Ugly Guy's Hot Daughter: Tazuna isn't seen as attractive, but she is.
Voiced by: Shizuka Ishikawa (JP), Mona Marshall (EN), Elsa Covián (LA Spanish)
Tsunami's jaded and cynical son. Inari's biological father died shortly after he was born, so he always considered Kaiza to be his father. However, after Kaiza's public execution he was overcome with grief and believed that all attempts to stop Gato would fail. Naruto helps him become a hero.
- The Bus Came Back: He and Tazuna briefly return after the Pain arc.
- The Cavalry: Shows up with all of the villagers from the Land of Waves to stop Gato's group of renegades.
- Character Development: When first introduced, he is cynical and cries a lot. Naruto helps him grow out of it and become a hero.
- The Cynic: When first introduced, he bitterly says that Naruto will be killed by Gato and claims that heroes don't exist. However, he grows out of it thanks to Naruto.
- Cynicism Catalyst: When Kaiza was executed by Gato.
- Hope Bringer: Eventually helps to inspire hope among the citizens of the Land of Waves.
- In the Blood: He becomes a bridge builder like his grandfather.
Voiced by: Akimitsu Takase (JP), Wally Wingert (EN), Salvador Delgado (LA Spanish)
A man who saved Inari from some bullies and quickly became part of his family. Inari always considered him his father. Was executed by Gato before the events of the Land of Waves arc.
- An Arm and a Leg: Gato had both his arms chopped off before killing him. Averted in the anime, where he only has them badly broken.
- Bully Hunter: Absolutely despises those who pick on the weak.
- Determinator: No matter what it costs him, he will protect what is precious to him.
- Good Scars, Evil Scars: He has an x-shaped scar on his chin.
- Parental Substitute: Inari always thought of him as his father, because his biological father died shortly after he was born.
- Posthumous Character: Was killed before the Land of Waves arc, but still had a character as clearly defined as the other characters from said arc.
- Second Love: Implied to be this for Tsunami, who lost her first love shortly after their son was born.
Voiced by: Yuko Sato (JP), Julianne Buescher (EN)
A kid who tried to steal Inari's dog Poochie when he was young, and nearly killed both Poochie and Inari.
- The Bully: He picks on Inari for no reason.
- If I Can't Have You...: If he can't have a dog, it must drown.
- Kids Are Cruel: Steals Inari's dog, then tries to drown it when Inari chases after him. He then throws Inari into the river, and leaves Inari there even though it's apparent that Inari can't swim. When one of his fellow bullies voices an objection, he threatens to drown the kid.

A man working on Tazuna's bridge. He quits for his own safety, but Inari later inspires him to come back and help fight Gato.
Land of Rain
Voiced by: Ikuya Sawaki (JP), Richard Epcar (EN)
The long-lived and legendary leader of Amegakure ("The Hidden Rain Village"). The reason Team Hiruzen is recognized as the Sannin is the fact that they were able to fight this guy to a draw. Pain later kills him and takes over Amegakure for his own goals, not that it prevents Kabuto from bringing him back to life with Edo Tensei.
- Asshole Victim: Pain destroyed him and everything ever connected to him. He personally had it coming, though maybe not everyone else connected to him.
- Authority Equals Asskicking: He was the leader of Ame and a ninja of legendary power, so much so that he was the one that named the Sannin such.
- Badass Transplant: His poisonous venom sac in his stomach.
- Black Eyes of Evil: Manga only. His sclerae seem to have been dyed that color from implanting a poison gland in his body and the toxins circulating through his bloodstream (eyes have blood vessels, too).
- Cool Mask: He wears one in order to prevent himself from dying of his poison.
- Crazy Survivalist: Paranoid and frequently takes extreme measures to neutralize anything he sees as a threat. Antagonizes a group of very powerful but non-violent ninja out of paranoia they might try to usurp him. This eventually comes back to bite him when he and everyone he's ever known gets killed in revenge for his Moral Event Horizon.
- The Dreaded: Again, the reason the Sannin are revered throughout the world is because they were able to survive - that is, not win, but survive - a battle with him. This was the case even years before he encountered the Sannin, where Hanzo had gained enough recognition to scare off a platoon of Samurai, with only Mifune staying behind to fight him.
- Fallen Hero: Hanzo used to believe in peace, and wanted to unite the Five Great Ninja Villages, but then he got cynical around the Second Shinobi World War, and became only interested in protecting his nation, and specifically himself, and maintaining his power. Even Nagato used to respect him, but after the Akatsuki hostage situation which killed Yahiko, he returned (in Yahiko's body, no less) dismissing him as a coward, and killed him.
- Monster Threat Expiration: Mifune even notes that his attack isn't as sharp as it used to be.
- Playing with Fire: His one jutsu shown (which uses exploding tags), other than his salamander summon, is stated to be a fire release.
- Poisonous Person: Implanted the venom sac of a rare and dead black salamander into his body, giving him resistance to poison and making his entire body toxic.
- Poisoned Weapons: The kama of his kusari-gama is coated with salamander poison.
- Posthumous Character: At least he was one until Kabuto revived him, anyways.
- Properly Paranoid: Justified, in the Naruto world, village leaders have very good reason to think people are out to get them or take advantage of their villages in some way or another. Danzo pulled this exact trick on Hanzo by pitting him and Amegakure against the Ame-orphans.
- Redemption Equals Death: Having been revived by Kabuto and then lost to Mifune, who lectured him about his lost faith, he regains his faith in peace and decides to cut open the salamander venom sac implanted in his body so he can be sealed, preventing Kabuto from taking control of him.
- Scars Are Forever: Has one across his right cheek.
- Seppuku: He cuts open his own stomach after his second fight with Mifune. However, the actual reason isn't suicide, but to cut open the salamander venom sac implanted in his body, thus allowing him to be sealed.
- Sinister Scythe/Epic Flail: His weapon of choice is a kusari-gama.
- Sparing the Aces: He used to spare the lives of enemies strong-willed enough to give him a good fight; he did this with both the Sannin (a Red Baron he coined) and Mifune.
- Super Speed: His speed was said to be unsurpassed over water.
- Trap Master: Prior to dealing with the Ame orphans, he had set up a bomb-trap in the event he got attacked.
- Well-Intentioned Extremist: While he was interested in uniting the Great Ninja Villages, Nagato mentioned that Hanzo's war efforts are part of the reason the Land Of Rain became such a hellhole in the first place. Once Hanzo gave up on peace, his people continued to suffer because of him until Nagato took him down. Hanzo is a case of this trope not being played sympathetically, as we've seen that the good intentions Hanzo had starting out did not make him any less of a bastard later in life.
- The Worf Effect: While he managed to fight the Sannin to a draw and once fought and won against Mifune, he is killed off-panel by Pain, to show how dangerous he is. Then when he is resurrected by Edo Tensei, he is beaten by Mifune to give the series' samurai some credit. However, it's justified when you consider that Pain is a Six Man Army who pretty much worfs everyone, including the entire Hidden Leaf Village. Mifune also implies that Hanzo's been somewhat out of practice since his prime.
- Worthy Opponent: To Mifune.
There were two main groups of genin from the Hidden Rain: Team Oboro and Team Shigure.
Team Oboro (consisting of Oboro, Mubi, and Kagari) fights Naruto's squad in the Forest of Death; as with many other Amegakure ninja, they all have rebreathers. Oboro is the one with two eyes visible; Mubi has one and Kagari has none.
Instead of having rebreathers, Team Shigure (consisting of Shigure, Midare, and Baiu) sports oxygen tanks and umbrellas. They confront Gaara and are very quickly killed.
- Automatic Crossbows: Mubi's crossbow, which can fire four shots at a time.
- Catch Phrase: For Oboro: "Lucky..."
- Coordinated Clothes: Strangely enough Team Oboro sports this.
- Dishing Out Dirt: Oboro's team seem to know Earth Release, since they can camoflage in the ground.
- Flechette Storm: Shigure can do this with his umbrella senbon.
- Informed Ability: Shigure is apparently a pretty competent ninja, but he never really gets to show it.
- The Leader: Oboro for his team, considering neither talks, its not surprising.
- Making a Splash: In the anime, Oboro and his team use water clones to fight.
- Master of Illusion: Oboros team employ illusions as their main battle tactic, both for tiring their targets and then during the actual fight.
- Meaningful Name: "Oboro" means "hazy"
- Parasol of Pain: Shigure specializes in senbon-shooting umbrellas.
- Put on a Bus: Team Oboro disappears after the Chunin Exams...
- Red Shirt: Shigure and his team are primarily used as a hint of Gaara's bloodthirsty nature and his potent power.
- Self-Duplication: Team Oboro can create Haze Clones.
- Squishy Wizard: Team Oboro; each one uses genjutsu to confuse and tire out their opponents, and then they go in for the kill. However, they are pretty hopeless when it comes to face-to-face fighting (though Oboro does demonstrate some skill in it during his fight with Sasuke and Sakura).
- The Worf Effect: When Kiba initially smells Team Shigure, he notes that while Shigure's chakra is very powerful, it's nothing compared to Gaara's.
- Worf Barrage: Shigure's enormous barrage of Senbon is quickly and easily blocked by Gaara.
Land of Iron
Voiced by: Katsumi Chou (JP), Kirk Thornton (ENG)
The general in charge of the Land of Iron, which is a neutral country with its own culture. It is unique among the countries, in that it is protected by samurai instead of hired ninja. He is a veteran soldier and a master swordsman, with a skillset that focuses on the use of Iai; the art of quickly drawing a sword for a slash before sheathing the sword again. He is so skilled with this technique that he is capable of interrupting ninja hand seals before they can be completed. As befitting a samurai, he is a poetic and philosophical man, and is not shy about sharing his ideals during fights with a Worthy Opponent.
He acts as host and mediator during the Kage Summit that the Raikage calls forth in response to the threat of Akatsuki. During this summit, he puts forth the idea of forming an alliance between the Great Ninja Villages in response to the Akatsuki threat. He suggests Danzo be appointed leader of the alliance, as his village has the last remaining tailed-beast host, but when Ao accuses Danzo of using a Mind Control technique (which he admits to) he is outraged. When Sasuke invades the meeting room, he's the first to try to attack Sasuke, though Sasuke blocks it and runs after Danzo. After hearing of Madara's plan, he agrees to have his nation join the alliance against him. In the war against Madara, he is the commander of Division 5 AKA the Special OPS Division.
- Acquired Poison Immunity: From surviving Hanzo's lethal salamander poison through a given antidote. It's put to great use when Hanzo is later Back from the Dead.
- Counterspell: His Iaijutsu is impeccable and most importantly, fast enough to interrupt any ninja trying make hand seals for Ninjutsu.
- Curb-Stomp Battle: Hanzo may have taken on all three Sannin by himself, but he can't even touch Mifune in their battle. Granted, Hanzo was much, much stronger and the Sannin much weaker back then, but it still shows how good Mifune is.
- There's also the very important factor of Hanzo having lost the drive he had in life.
- Helmets Are Hardly Heroic: Mifune goes helmetless for the Fourth Shinobi World War while still wearing armor.
- Four-Star Badass: General of the samurai and a more than capable fighter himself.
- Iaijutsu Practitioner: A master of the technique and fast enough with it to intercept a ninja about to perform hand-seals.
- Katanas Are Just Better: A samurai in a series about ninja where swords of any kind are pretty rare.
- Laser Blade: Not completely straight, but the chakra surrounding their blades have essentially the same qualities as one.
- Mage Killer: Sort of, in that he doesn't have ninjutsu or genjutsu, but just plain uses his mastery of Iai to stop enemy ninja from performing jutsu.
- Master Swordsman: Specifically known as a master of Iai, he's shown to be one of the best swordsmen in the series.
- Named After Somebody Famous: His name comes from the actor Toshiro Mifune, who is famous for his numerous roles as samurai and ronin. As well as that, his sword Meitou Kurosawa is named after the director Toshiro Mifune frequently worked with, Akira Kurosawa.
- Named Weapons: His katana is named Meitou Kurosawa.
- Old Master: He's old but still strong enough to go mano e mano with Hazo.
- Reasonable Authority Figure: Mifune is a calm and wise leader with a neutral viewpoint upon the conflicts of the ninja villages. During the Kage Summit, in which he is host, he suggests the Kages form an alliance against Akatsuki. He also decides to join this alliance with his samurai after hearing of Tobi's plans.
- Single-Stroke Battle: Mifune and Hanzo engage each other in one twice. Once in the distant past, where Hanzo won, and now in the current time, where Mifune wins.
- Spellblade: He and the other samurai are capable of channeling chakra through their swords into various shapes.
- Super Mode: Gains a chakra cloak thanks to Naruto giving him chakra which greatly increases his power.
- Sword Beam: He can use chakra against foes for a devastating ranged attack.
- Talking Is a Free Action: Engages in a little philosophical debate in his first fight, which does not appear to impede him much.
- Warrior Poet: Quite appropriate seeing as he is a samurai, also has shades of The Philosopher; when we finally see him in battle, Mifune explains his philosophy on the nature of violence, peace, and heroism as he fights. The time spent making these points didn't seem to give his opponent much of an edge.
- Worthy Opponent: To Hanzo after defeating him.

The chief toad of Mount Myoboku. He is the personal summon of Jiraiya.

One of Kakashi Hatake's ninken (ninja dogs) and by far the smallest one. His stature prevents him from being used physically; his specialty instead lies on tracking.
- Canine Companion: While not as overt as Akamaru, he is summoned often by Kakashi to do missions.
- The Nose Knows: His main use.
- Talking Animal: One that is as surprising to the characters as the audience. He only starts speaking during the Konoha Crush arc.

Akamaru is Kiba Inuzuka's dog. As with dogs of other members of the Inuzuka Clan, Akamaru is much more than a simple pet, being Kiba's close partner. He accompanies Kiba wherever he goes and assists him in performing techniques.
- Babies Ever After: The epilogue shows that he has a litter of pups.
- Beast of Battle: Kiba fights alongside him.
- Big Friendly Dog: His appearance is similar to multiple large livestock guardian dogs (the Great Pyrenees chief among them, along with the Maremma, the Cuvac, and the Kuvasz) and he undergoes explosive timeskip growth, matching the transition from puppyhood to adulthood.
- Canine Companion: To Kiba.
- Canis Major: Akamaru gets a lot bigger in Part II.
- Combination Attack: Part of the reason he always tags along with Kiba is so they can do this.
- Food Pills: Before Part II, Kiba and Akamaru had to rely on the use of chakra-boosting Food Pills to efficiently use their ninjutsu.
- Fusion Dance: He can fuse with Kiba into a giant two headed dog.
- Head Pet: In Part I, he is small enough to ride on Kiba's head.
- Heroic Dog: Known for protecting cats and kids all around Konoha from mean dogs, often as Kiba translates: 'Pick on someone your own size!'
- Horse of a Different Color: Kiba rides on Akamaru in Part II.
- Intelligible Unintelligible: Kiba apparently can understand what he says.
- Long-Lived: By dog standards, Akamaru is incredibly long lived, as he is still alive in the epilogue, where he is around 23 years old. Though by that time, he looks pretty old and is likely retired.
- Nearly Normal Animal: Unlike Kakashi's ninken, Akamaru does not speak human language and acts mostly like a normal dog, albeit with a heightened intelligence.
- Old Dog: In the epilogue.
- The Patriarch: By the epilogue, he is father to a litter of pups and also watches over Tamaki's cats and kittens.
- Satellite Character: He doesn't get much of a character, except for being Kiba's partner and best friend.

- Intelligible Unintelligible: Tsunade and Shizune seem to understand what she says.
- The Nose Knows: She is able to sense debt collectors coming for Tsunade from miles away.
- Pint-Sized Powerhouse: Downplayed. During the Fourth Ninja World War, she serves as a courier for the logistical and medical devision and is seen carrying crates larger than she is.
- Running Gag: Being mistaken for food. Shizune's preface for her subordinates in the Ninja Alliance's Logistical and Medical Division is to tell them not to mistake Tonton for food.

A giant snake from Ryuchi Cave and Orochimaru's personal summon.
- Arch-Enemy: With Gamabunta.
- Attack of the 50-Foot Whatever: He is bigger than both Gamabunta and Katsuyu.
- I Am A Humanitarian: Demands a hundred human sacrifices in return for helping Orochimaru during the Three-Way Summoning Battle.
- Killed Off for Real: Sasuke summons him to shield himself from Deidara's C0. He actually survives for a short time to curse Sasuke for his death.
- Shout Out: His namesake is the snake-like kaiju from Godzilla.
- Snakes Are Sinister: And very big. He is also actively malicious to not only his enemies, but his master as well.
- The Starscream: Unlike Gamabunta and Katsuyu, Manda appears strictly on contract basis and has no real bond with Orochimaru. He only obeys Orochimaru because he was defeated by him and demands a sacrifice in return for his service.
- Tongue Trauma: Tsunade stabs his mouth from the top using Gamabunta's tanto, rendering him unable to chew anything for a month.

A giant slug from Shikkotsu Forest and Tsunade's personal summon.
- Acid Attack: Its main offensive attack is this. The acid is strong enough to melt rock.
- Ambiguous Gender: Though the anime gives it female voice actors, Katsuyu is never referred to by gendered pronouns. This is a reference to real-life slugs, which are hermaphrodites.
- Attack of the 50-Foot Whatever: In its ordinary form.
- Healing Hands: Tsunade often uses it as an effective way to channel her healing jutsu and distribute it to a large number of people. Particularly evident during Pain's invasion, where Katsuyu reaches out to Konoha's entire surviving population.
- Hive Mind: All the little slugs that it splits into share the same mind. This makes it handy for it to relay information across great distances.
- Implacable Man: Katsuyu's main trick when about to be attacked is by dividing itself into smaller slugs and back again, and it can do it as many times as it wishes. Combined with the fact that the slugs are themselves extremely resistant to damage, it's unknown if Katsuyu is able to be wounded at all. It can get weaker, but only if the summoner is also out of chakra.
- Keigo: In keeping with its status as a loyal summon, it speaks formally with everyone. It calls Tsunade "Tsunade-sama" and others with "-san".
- Meaningful Name: "Katsuyu" is the Sino-Japanese reading of 蛞蝓, normally read in Japanese as "namekuji", which means slug.
- One to Million to One: Dear god. Unlike the frogs and snakes, who have multiple different members, every single slug seen in the series is a Katsuyu. Also, Tsunade and Sakura can summon two different same-sized Katsuyus at the same time, even though that size is as tall as a Tailed Beast. Apparently, the size Katsuyu appears as and its power depend on its summoner's chakra. It's possible that Shikkotsu Forest has only "one" inhabitant, that is, a hive of slugs named Katsuyu.
Gamahiro and Gamaken
Voiced by: Takeharu Onishi (JP, Gamahiro), Atsushi Ono (JP, Gamaken), Dave Wittenberg (ENG, Gamahiro), Kyle Hebert (ENG, Gamaken)
Two large toads at Mount Myoboku who are Gamabunta's equals.
- Attack of the 50-Foot Whatever: As big as Gamabunta.
- Blade on a Stick: Gamaken carries a sasumata, a polearm with a fork at its end.
- Frog Ninja: Two of many that are summoned throughout the series.
- Katanas Are Just Better: Gamahiro wields a pair of katana.
- Shout Out: Like Gamabunta, their names are homages to yakuza films. Gamahiro references Hiroshima, the city stereotyped for its yakuza activities and whose dialect is spoken by Gamabunta. Gamaken, meanwhile, references the late Ken Takakura, who was something of a rival to Bunta Sugawara.
Fukasaku and Shima
Voiced by: Ikuo Nishikawa (JP, Fukasaku), Hikari Yono (JP, Shima), Kirk Thornton (ENG, Fukasaku), Mary Elizabeth McGlynn (ENG, Shima)
Two elderly toads of Mount Myoboku. They are respected as the Two Great Sage Toads.
- Alien Lunch: Since they're frogs, Shima's always cooking insect-themed foods such as "larvae ramen". Naruto (and Minato in a filler scene) finds most of it disgusting, although at one point he admits that the bento she made for his Sage training was actually good. The other toads in Mount Myoboku universally think that she's a Supreme Chef.
- Back from the Dead: Pain kills Fukasaku during the invasion of Konoha, but later brings him and the other dead Konoha nin back.
- Battle Couple: They work in tandem.
- Combination Attack: With Jiraiya, they can perform Sage Art: Goemon.
- Expy: Fukasaku is one for Yoda: both are small centuries old, green creatures, who taught both The Obi-Wan and The Hero of their respective franchises.
- Frog Ninja: Frog Sages.
- Happily Married: They have been a couple since the time Jiraiya first visited Mount Myoboku.
- Killer Rabbit: They are the same size as Gamakichi and Gamatatsu in Part I, but are some of the most powerful animals on the planet.
- Master of Illusion: They're capable of using Genjutsu through their frog song, that's powerful enough to entrap the Paths of Pain.
- Mentor Occupational Hazard: Fukasaku briefly experiences this, though he gets better.
- Old Master: The two are among the most senior toads at Mount Myoboku.
- Multi Purpose Tongue: Shima can use a jutsu that transforms her tongue into a snake like creature capable of sniffing out hiding enemies, long enough to tie-up Pain's Chameleon summon, and has pimples filled with acid on it's surface.
- Pintsized Powerhouse: Fukasaku is roughly the size of a cat, but can lift and hurl Gamabunta.

The famed Great Toad Sage of Mount Myoboku.
- Attack of the 50-Foot Whatever: He is as big as Gamabunta.
- Been There, Shaped History: According to the anime, he's the one who revealed Kaguya Otsutsuki's true nature to his sons, and he's the one who taught Sage mode to Hagoromo.
- Cool Hat: Wears a professor hat.
- Elderly Immortal: He is alive since before the sealing of Kaguya Otsutsuki and the creation of the Tailed Beasts. He is the oldest known being on Earth.
- Hermit Guru: The oldest denizen of Mount Myoboku.
- Old Master: He is older than Fukasaku and Shima, who are themselves extremely old.
- Only Known by Their Nickname: Gamamaru is only called the "Great Toad Sage" (Oogama Sennin) in the series. His name is revealed in a databook.
- The Prophecy: His prophecy to Jiraiya is a focal point of the series.
- Scatterbrained Senior: Has gotten rather senile in the present.
- Seers: His talent is Dreaming of Things to Come.
White Snake Sage
Voiced by: Hiroko Suzuki (JP)
The famed snake sage of Ryuchi Cave, a counterpart of the Great Toad Sage of Mount Myoboku.
- Ascended Extra: In the original series, she only appears in flashbacks. We get to see her in Boruto.
- Attack of the 50-Foot Whatever: By far the largest snake in the series, her body coils around the room she is in multiple times and basically merges with the ground.
- Graceful Loser: She concedes to Boruto after he manages to do her Impossible Task and tells him Mitsuki's location.
- I'm a Humanitarian: The punishment for turning into a snake during senjutsu training is being eaten by the Snake Sage.
- Impossible Task: She tasks Boruto and his friends to bring her Garaga's scale, thinking that there is no way they can defeat the feared rebel of the cave. She is surprised when Garaga actually becomes Boruto's summon.
- Nice Hat: Wears a hat with a reddish brown wig.
- Only Known by Their Nickname: Her true name is never revealed.
- Reasonable Authority Figure: Anyone who passes the tests of the three snake princesses has a right to study under her.
- Samus Is a Girl: The Sage's gender is not known in the manga. Boruto reveals that she is female.
- Snakes Are Sinister: It's explained that, unlike the Toad Sage, the Sage Snake is a dangerous individual to deal with. Orochimaru never becomes a Sage because he never meets her expectation. She does kill students who fail her test, though if they pass she will not hesitate to congratulate them.
- Stern Teacher: Studying senjutsu is a difficult affair and the punishment she gives to individuals who fail the training and become snakes — eating them whole — is not that different to the petrification of students in Mount Myoboku who turn into toads.
- Voluntary Shapeshifting: Like the snake sisters, she can transform into a human, in her case an old lady.

A snake of Ryuchi Cave and Sasuke's personal summon.
- Ascended Extra: Aoda has more to do in Boruto.
- Babies Ever After: It's mentioned in Naruto Shiden, set during the events of Boruto, that Aoda is a great-grandfather.
- Contrasting Replacement Character: Although clearly intended as a replacement for Manda, he could not be more different in personality. Aoda is polite, subservient, and does not demand a sacrifice.
- Papa Wolf: In Boruto, he extends the protectiveness he gives to Sasuke to his entire family. When Sarada and her friends are attacked by Garaga, Aoda quickly appears to save them, despite the fact that Garaga is feared by other snakes of the Ryuchi Cave.
