This is a partial character sheet for Avataro Sentai Donbrothers. Subjective trope and audience reactions should go on the YMMV page.

Emblem of the Nōto

Known as Ideon to the Nōto themselves, it is a hidden metaverse that overlays onto Earth, which hosts the Nōto and the Anōnis, while also being linked to and affected by the Hitotsu-Ki.

Nōto^note 脳人

The antagonistic group that opposes the Donbrothers. They seek to eliminate greed-consumed humans to purge the power of desires that disrupts the Nōto Layer.

General Tropes

• Brutish Bulls: Their emblem heavily resembles a bull's head. They're also the show's primary villains.
• Civil War: Revealed to have caused one. The Nōto violently deposed the royal family of Ideon in response to the latter's attempts to co-exist with humans, nearly wiping them out in the process.
• Color-Coded Characters: Each of the Nouto generals has a specific colors associated with them: Sonoi - blue, Sononi - white, Sonoza - brownish orange, and later on Sonoshi - red, Sonogo - purple, and Sonoroku - silver.
• Contrasting Sequel Antagonist: While the Tozitend Dynasty members were unapologetically cruel in their quest to subjugate all of the parallel worlds, the Nōto are moreso dangerous vigilantes than Card-Carrying Villains; only cutting the Hitotsu-Ki down to stabilize their own world. They still have their own moments of cruelty however, like what happened to the Don Clan. The Overseers, however, are far more like the Tozitend Dynasty.
• Create Your Own Hero: The Nōto massacred the royal family of Ideon in a past war. Said family sent their heirs to Earth, who would grow up into Don Momotaro and Don Doragoku/Don Torabolt, their biggest opponents in the modern day.
• Creative Sterility: They view things like art and emotions to be beneath them as coping mechanisms for humans to cover for their imperfections, since the Nōto believe themselves to be perfect.
  • #13 shows that they are incapable of anything that is imperfect, like art as even when Sonoi prepares a paper, a pencil and a view to draw, he finds himself physically unable to create anything.
  • When Taro visits Ideon as a guest at Sonoi's funeral, he points out that Nōto food is bland and tasteless, even if it's designed to be nutritious.
  • Is eventually Played for Drama during the show's final quarter: the primary Trio's exposure to humanity and fraternization with the Donbrothers shapes them into more emotionally-adjusted people. Ideon's council sees this as treason and abandons them in favor of Sonoshi's group.
• David Versus Goliath: The Nōto are practically flies in the face of the savage Jūto monsters, who they can't even land a hit on.
• Disproportionate Retribution: In response to the Don Clan's intent to co-exist with humanity, the Nōto massacred them to the man; with the Council even prioritizing the murder of any surviving members. Subverted in #27, where it's revealed that the same clan created the Juto.
• Evil Counterpart: The main Noto trio start off as this to the Donbrothers, being vigilantes motivated by Fantastic Racism to exterminate Hitotsu-Ki instead of liberate them like the heroes. They eventually develop redeeming traits and become friends with the heroes on their down-time, leading to the Noto Council bringing in Sonoshi and their associates as crueler substitutes.
• Evil Versus Evil: Compared to villainous groups of Sentai past, the Nōto are in fact opposed to the Monster of the Week like the Donbrothers are, yet also have the ability to create them. They're also fighting the much-stronger, much-viler Juto monsters.
• Fantastic Racism: They are a group of Superior Species who believe they are above humanity, a certain number of which they believe are too tainted by desire and greed and should be disposed of, moreso by their own hands as they disapprove of the Donbrothers allowing the human that became it to survive.
• Headbutting Heroes: At the skin-deep level, this is the Nōto's relationship with the Donbrothers. Both groups protect people and both oppose the Monster of the Week (and the Juto). What puts the two at odds is how far the Noto are willing to go compared to the Donbrothers, stemming from their inability to see humans as anything more than "imperfect". Best exemplified in #25, where both Sonoi and Taro each declare the Hitotsu-Ki game for their respective factions.
  Sonoi: The Hitotsu-Ki are supposed to be defeated by the Noto!
  Taro: No! The Donbrothers are supposed to defeat the Hitotsu-Ki!
• Just Toying with Them: While Don Momotaro enjoys Villain Respect from Sonoi for his battle prowess, The Nōto treat the rest of the Donbrothers as a gang of petty distractions at best. Following the revelation that they're led by a member of the Don Clan though, they're considerably more prone to instigating conflict with them directly. This trails off over time, as the generals single out Donbrothers that intrigue them and start becoming kinder through their influence.
• Mark of the Supernatural: All three generals have uniquely colored eyes that relate to their armored forms. Sonoi has Occult Blue Eyes, Sononi and Sonoroku have Icy Grey Eyes, Sonoza has Supernatural Gold Eyes, Sonoshi has Red Eyes, Take Warning, and Sonogo has purple eyes.
• Meaningful Name:
  • In kanji, it translates to "Brain People".^note Over-Time translates this as "Cerebrans" Their home dimension is literally made from human thoughts.
  • The Behind The Scenes All There in the Manual states that before it was properly named Ideon, "Nōto Layer" is a reference to how "layers" in Photoshop are overlaid onto an image, which can be toggled into or out of view, much like how this metaverse works with the real world.
• Nice Job Breaking It, Hero: Of the Knight Templar variety. The Noto's destruction of the Don Clan ensured that the Juto had almost nothing that could stop them from infiltrating humanity.
• Nominal Hero: The Nōto only save humans to stabilize their realm. They look down on humans at the best of times and have no qualms about murdering their opponents. It's much more blatant after Sonoshi's group replaces Sonoi's, being a trio of thugs with none of their predecessors' redeeming qualities.
• Non-Standard Character Design: Previous Sentai villain groups are usually made with the majority of their commanders in monster forms with only a few commanders even having a sentai-like/Psycho Ranger form. This is the first Sentai where all the commanders are human-looking and transform into sentai-like forms.
• Not So Above It All: The Nōto look down on people for their "imperfect" art and emotions, but spend much of their time mimicking these behaviors themselves. As the series goes on, they also start to get into more wacky situations and are influenced into positive change through the friends they make on the enemy team.
• Numerical Theme Naming: Their generals revealed so far are named after the Japanese terms for "Part One/Sono Ichi", "Part Two/Sono Ni" and "Part Three/Sono San". #37 introduces a new one, Sonoshi, which is "Part Four/Sono Shi", with #45 further introducing Sonogo ("Part Five/Sono Go") and Sonoroku ("Part Six/Sono Roku"). #49 brings in the final villains Sonona ("Part Seven/Sono Nana") and Sonoya ("Part Eight/Sono Ya").
• Punny Name: Certain media tend to spell their name in katakana as Nōto/ノート, which instead translates to "Note(book)" in English. This may be the official English spelling for their group.
• Ruling Family Massacre: The Noto slaughtered the entirety of the ruling Don Clan in a Civil War and took Ideon for themselves. Taro and Jiro survived the massacre and were spirited to the human realm, where Jin and Terasaki found and raised them.
• Shout-Out: Their designs are based off past Toei Tokusatsu productions.
• Thou Shalt Not Kill: Zig-zagged. What separates the Nōto from the Donbrothers is their willingness to murder their Hitotsu-Ki opponents, most of whom are humans forced against their will into hostile monsters. However, #15 reveals they don't kill all of their opponents; most of them are housed in an Extranormal Prison as opposed to dead. This also means they can simply turn into Hitotsu-Ki again, meaning their methods are still unnecessarily cruel compared to the Donbrothers'. Though, #46 reveals that, via the Ring of Forgiveness, the ones they managed to kill, along with the people they've imprisoned, are brought back.
• Transformation Trinket: The generals have one in the form of the Nōto Brace each of them wears, activated by waving their hand over it. The emblem on it then becomes their chest armor.
• Well-Intentioned Extremist: What they're doing to humans is horrible, but the reason they're doing it is because human desire is destabilizing their home dimension.
• What Measure Is a Non-Human?: Invoked. They have the ability to purposely evoke a human's evolution into a Hitotsu-Ki in order to justify having to execute them.

Leadership

The Council

Red Councilman portrayed by: Nobuo Tobita (voice), Yasuhiko Imai (suit)
Blue Councilman portrayed by: Shinpachi Tsuji (voice), Shinsuke Kusano (suit)

The ruling body of Ideon.

---

• Malevolent Masked Men: The leaders of the show's primary enemy faction have masquerade masks over their faces, along with black hooded cloaks.
• Nice Job Fixing It, Villain: The Council's half-hearted attempts to curb its generals Going Native eventually sparks a Hazy-Feel Turn out of the primary trio, who free the captive Hitotsu-Ki hosts in an attempt to curry favor with the Donbrothers..
• Not So Above It All: After calling the Council out for sticking their funeral invitation inside of his sandwich, Taro orders them to eat the lunch since he couldn't. They actually do.
• The Omniscient Council of Vagueness: Not much is known about them as of yet, other than the fact that they give Sonoi, Sononi and Sonoza (and later Sonoshi and their thugs) their marching orders and are behind the extermination of the previous rulers of their world, the Don Clan. They finally appear for the first time in episode 29, during Sonoi's funeral.
• Orcus on His Throne: Subverted. The Council does extract Taro's energy for Sonoi's revival and is the authority overseeing both of the Noto Trios, but they mostly sit around while their proxies talk and act on their behalf.
• The Unfought: Despite being the Greater Scope Villains of the series, only Taro gets to meet them directly, and they never appear again for the rest of the series after #29.
• You Have Failed Me: They dispatch Sonona and Sonoya to execute the Trio and Overseers, for the latter two's repeated failures to kill Don Momotaro.

Sonona and Sonoya

Sonona portrayed by: Yuka Motohashi (live), Nagisa Tabata (suit)
Sonoya portrayed by: Kohei Murakami (live), Shinsuke Kusano (suit)

A couple of assassins in the employ of the Nōto Council.

---

• Badass Normal: They are able to go toe-to-toe with Armored!Sonogo and Sonoroku in their human forms.
• Big Bad Duumvirate: They serve as the series' final main antagonists.
• Co-Dragons: They are executioners that directly answer to the Council, superseding even the Overseers in rank.
• Curb-Stomp Battle: On both the giving and receiving end. The Overseers are absolutely powerless against the Executioners and are brutally wiped out one-by-one before they can even so much as react. The combined force of heroes later on are barely even enough to dent them - If it wasn't for Taro regaining his memories at the last second and jumping in, it would not have been a contest. Once he does show up though, the tables landslide in entirely the opposite direction; a high-powered Finishing Move being enough to decimate the two wholesale.
• The Dreaded: Even more so than the Overseers, who actually react in full-blown terror at the sight of them.
• Dual Wielding: Sonoya wields the Sanzenkon and the Ninjarksword during his fight in #50, after stealing Sonoroku's powers.
• Evil Sounds Deep: Sonona has the appropriately low voice, with Kohei Murakami using a raspy, guttural voice for Sonoya.
• In a Single Bound: Can leap great distances and heights.
• Knight of Cerebus: Subverted. The duo's only defining moment is killing off each of their Overseers in as brutal a fashion as a kid's show lets them get away with; emphasis being placed on what Dreaded No Nonsense Nemeses the duo are. The united coalition of Donbrothers are not enough to take them down, even with Murasame defecting and joining the Donbrothers to help out. Taro is the only force able to stop them and that's after barely holding off his memory loss to do so. But once he is in full form, the power-gap is so laughably wide that his assigned role call hurts them.
• Painting the Medium: Exploited and Parodied. Taro is so far above these two in power that his presence gives the team's season logo a Battle Aura that swats the two enemy generals aside with ease.
• Maniac Tongue: They activate their Noto Braces by licking them.
• Power Parasite: They steal Sonogo and Sonoroku's powers.
• Slasher Smile: Murakami's signature returns in its frightening glory.
• Verbal Tic:
  • Sonona has a habit of finishing her sentences with some variation of "not that I care", showing her deceptively nonchalant attitude.
  • Sonoya has a habit of repeating words.
• We Hardly Knew Ye: They are killed by Don Momotaro a mere episode after their introduction.
• White Hair, Black Heart: Sonoya has hair as white as the driven snow, and callously torments Sonogo by stealing her powers and killing her afterwards.
• You Have Failed Me: Sonona and Sonoya are the living embodiments of the Council deciding this about the Overseers. Before they even fight the heroes, they dispatch their minions first.

The Overseers

In General

• Asshole Victim: They all get unceremoniously executed by Sonona and Sonoya under orders of the Noto Council, and considering the torment they have inflicted upon Sonoi and his party and the needless cruelty to humans, it's safe to say they got a taste of their own medicine.
• Blow Gun: All three of them sport one that can cause a person's desire to go berserk, attracting a potential Hitotsu-Ki power that turns said berserk human into a Hitotsu-Ki. Further darts will then cause the Hitotsu-Ki to prolong their berserk state.
• Create Your Own Hero: Downplayed. Sonoi's trio were already toying with the idea of defecting to the Donbrothers, which is what the conference they attended was for. However, Sonoshi's group forcibly influencing the votes to bunch their enemies together becomes one of the catalysts (the other being Taro's Batman Gambit) to unite the factions into an army the Overseers cannot compete with.
• Embarrassing Nickname: Sonoi comes to collectively calling the group Sonoshigoroku, an amalgamation of all their names. This ends up being heavily used by the Donbrothers, to the Overseers' dismay.
• Evil Counterpart: All of them are this to the original Nōto trio:
  • Sonoshi is one to Sonoi if his appreciation for human art and beauty was not filtered out by his inherit, yet ironic, humanitarian nature to do good.
  • Sonogo is one to Sononi with both of them being the sole female of her trio and quite the Dude Magnet, but while Sononi is curious about love and the romantic dynamics between, Sonogo focuses more on physical beauty. She also wields a melee weapon rather than a ranged one.
  • Sonoroku is one to Sonoza, both serving as The Brutes in their respective trios. Sonoroku's emotions function normally (his jerkassery notwithstanding), he is an exercise nut/more physically-oriented, and has a brawny frame, while Sonoza has a lankier build, is more interested in manga, and is initially emotionally-disjointed. Sonoroku also wields a mace in contrast to Sonoza's spear.
• Evil Is Hammy: Compared to the fairly stoic-turned-comically serious Trio, the Overseers are more than willing to ham it up despite being soft-spoken.
• For the Evulz: Sonoshi's group are perfectly-willing to attack humans unlike their predecessors, reveling in the chaos stemming from it as they do. Sonoroku especially stands out for throwing an infant into the Phantom Zone.
• Irony: The primary Noto trio's character arc centers on them slowly developing "imperfect" emotional centers and dreams of their own via their enemies' influence. Sonoshi's group by contrast is more emotional and expressive from the start, but also nowhere near as moral.
• Laughably Evil: They act so over the top when performing evil acts, it is more funny than threatening.
• Nice Job Fixing It, Villain: Sonoshi and their cohorts convince the Donbrothers to add the former trio to their ranks so they can murder everyone at once. All they did was form a proper coalition easily able to stand up to them.
• Shadow Archetype: These three are essentially the previous Noto trio without restraint, ambition or morality; each of their traits amped up to hostile extremes.
• Sucksessor: Villainous example. Compared to the Noto trio, Sonoshi's group is nowhere near as capable. They aren't particularly united and are more prone to gripping the Villain Ball; resorting to trickery and engaging in hammy antics that lead to frequent losses. When the Executioners reveal themselves, their very first act is to deem the Overseers failures.
• Teeth-Clenched Teamwork: Downplayed. While the trio are able to work in-tandem perfectly fine, they are not bound by honor and respect like their predecessors are. Sonogo and Sonoshi secretly loathe one another and Sonoroku is apathetic to their shenanigans.
• Troll: The trio demonstrate an innate glee in toying with others. The trio take hyper-manic glee in tormenting their predecessors (Sonoshi outright states they want to prolong their suffering) and have all needlessly attacked humans at some point, be it for The Plan or For the Evulz.
• Villain Decay: A self-inflicted one. Their arrival in the final episodes only manages to strengthen the Donbrothers by driving the original trio to join them, and the Overseers find they can't handle nine opponents at once, especially when three of them are Taro, Jiro, and Sonoi, and the actions they take afterwards backfire horribly. Sonona and Sonoya note the Overseers have been colossal failures after seeing the Ohsama-Ki debacle and act accordingly.

Sonoshi

Portrayed by: Tomoki Hirose (live), Kenya Saito (suit)

Cleanliness first and foremost! Sonoshi!

Armored form

Skin: Akahade Mask

The Chief Inspector of the Nōto, assigned by the Council to supervise their fellow generals.

---

• Agent Peacock: They're very flamboyant even by Nōto standards, but nevertheless can fight all five Donbrothers to a standstill by themselves.
• The Caligula: They behave like a tyrannical despot towards their kin and have no qualms abusing their power against those they deem disobeying the Council's orders.
• Chewing the Scenery: They, along with Sonogo and Sonoroku jubilantly celebrate at Sonoi and his companions being excommunicated from the Noto in a more over the top way possible.
• Devious Daggers: Their primary weapon is a stiletto blade called the "Red Shadow", which can be extended into a whip.
• The Dreaded: Being an elite officer within the Noto's higher-ups, Sonoi has a very good reason to fear Sonoshi whenever they appear before the main Noto trio, in that they are rather oppressive to anyone who they deemed guilty of insubordination towards the Council didn't help matters either.
• Enemy Summoner: They can summon Anoni by playing their ocarina.
• Establishing Character Moment: They make their presence known to the Donbrothers and Nōto by rudely shoving them aside, setting up a plastic screen and spraying disinfectant on the table, and disrespecting the oden shop's fare to the owner's face.
• Evil Is Petty: Sonoshi has no problem inflicting unnecessarily cruel acts of violence for no reason whatsoever other than spite against Sonoi and his companions. Even their fellow Overseers will just play along with them.
• Eviler than Thou: Sonoshi stands out as one of, if not entirely, the cruelest and the most heartless enforcers within the Noto's higher ranks and using that position of power to put anyone who defies them their place. It's no wonder why the main trio had to reach out to the heroes to stop them.
• Faux Affably Evil: Sonoshi puts on the airs of being a cultured, honor-bound warrior not unlike Sonoi that defends Noto honor. They quickly reveal themselves to be little more than a thug in fashionable clothing that's perfectly willing to attack humans and bully their own allies to enforce their own standards.
• Hate Sink: They are currently the most deplorable Nōto as of yet: condescending, arrogant, tyrannical and deceptively violent; bullying the main trio with their status as a bludgeon and even using the Anoni as makeshift thugs to swat humans aside. They're such a deplorable person that the Noto and Donbrothers actively set their feud aside to take them down a peg.
• In the Hood: They're first spotted spying on the other Nōto in a golden mask and hooded cloak.
• Jerkass: Their debut shows themselves to be an arrogant, oppressive wretch, abusing their superior position and bullying the three generals with the excuse of discipline, along with having a condescending manner and sadistic glee to both sides.
• Large Ham: They come off as rather animated and prone to make over-the-top gestures when excited.
• Neat Freak: Aside from the aforementioned Establishing Character Moment, they intrude on Donbura, spraying disinfectant everywhere. Even their idea of punishment for the rest of the Nōto is hygienic: infinite floor scrubbing duty.
• Non-Human Non-Binary: According to production notes, they are this.
• The Political Officer: Per their status as a "superior," they're this to the main Noto trio - sent specifically to investigate (and put a stop to) their friendliness toward the Donbrothers.
• Red Eyes, Take Warning: They have red eyes, and appropriately are the most unlikeable Nōto seen in the show.
• Red Is Violent: They takes on a red bird-like form and are also the most violent general so far, even sic'ing Anoni on people to "cleanse" an area they don't like.
• Shadow Archetype: They're essentially Sonoi without conscience, honor or friends; using their authority to oppress those weaker than them.
• Shout-Out: Their armored form is designed after Kamen no Ninja Akakage.
• Solid Gold Poop: Their earwax is apparently made of gold.
• Token Evil Teammate: While the main Noto trio are vigilante-minded enforcers driven by Fantastic Racism and a willingness to Kick the Dog, Sonoshi doesn't even try maintain that crusader illusion: being a domineering tyrant with a massive ego that's willing to hurt innocent humans and bully their allies to get their way. The other generals actively defy them and work with the Donbrothers just for a chance to get some payback.
• Troll: When they're not being an abusive elite officer towards Sonoi and his party, they outright troll them to the point of making their lives into a living hell, even so after Sonoi and his cohorts are excommunicated. Their other subordinates, Sonogo and Sonoroku also revel at their misery adding further salt to the wound.
• Undignified Death: In comparison to Sonogo and Sonoroku who at least to tried fight back their execution, Sonoshi ran for the hills as soon as Sonona and Sonoya came for him, and was unceremoniously slaughtered without putting up a fight.

Sonogo

Portrayed by: Mana Takai (live), Nagisa Tabata (suit)

The best in beauty! Sonogo!

Armored form

Skin: National Fit

A mature woman determined to be the most beautiful in the world, bar none.

---

• The Baroness: She's rather rough around the edges underneath her attractive appearance.
• Depower: She gets her armored form stolen by Sonona before being killed by the latter.
• Establishing Character Moment: She's established as an Evil Counterpart to Sononi when she attracts the gaze of a suitor that had been trying to woo Sononi, then shoves the poor guy's face into her plate of spaghetti.
• Fairest of Them All: She appears to be quite vain, as seen from her spending time in front of her mirror, as well as stopping random couples on the street and demanding to know who the most beautiful woman in the world is.
• Graceful Ladies Like Purple: Defied; her clothing features various shades of purple, her armored form is purple, and she wields a rapier — a weapon with a reputation for elegance — but she is far from dainty and graceful, as the unlucky suitor found out the hard way.
• Royal Rapier: Her primary weapon is a rapier named the Kid Rapier.
• Shout-Out:
  • Her armored form is designed after National Kid.
  • Her Morton's Fork interrogation regarding her beauty in #47 appears to be one to the Japanese urban legend of Kuchisake-onna.
• Super-Breath: Her breath is powerful enough to send full-grown adults flying into the sky.

Sonoroku

Portrayed by: Shin Koyanagi (live), Shinsuke Kusano (suit)

A big fan of kindness! Sonoroku!

Armored form

Skin: Choukou Crystal

A boisterous man with a rather warped notion of kindness and charity.

---

• Bad Samaritan: He loves to "help" people. And by "help", he means throwing their stuff into the Phantom Zone, including a carriage with the baby still inside.
• The Brute: Like Sonoza to Sonoi, Sonoroku serves as this to Sonoshi, though he fits the archetype more so than Sonoza, physically and weapons-wise.
• Carry a Big Stick: Wields a giant six-pointed mace named the Sanzenkon in combat.
• Depower: He gets his armored form stolen by Sonoya before being killed by the latter.
• Dumb Muscle: Compared to Sonoza, who is interested in emotions, Sonoroku relies on his twisted pride of strength and brute force.
• Establishing Character Moment: He's built up as Sonoza's rival by rudely interrupting the latter's manga reading, earning Sonoza's ire as a result.
• Even Evil Has Standards: Implied in #47 when Sonoshi and Sonogo caused some ruckus to draw the Donbrothers, Sonoi & his co, but Sonoroku himself comically stated he wouldn't go that far. Ultimately averted in the immediate next episode.
• Fourth-Wall Observer: #47 has him look into the camera while cracking a joke.
• Jerkass: Deliberately interrupts Sonoza by knocking away his manga and calling it "trash".
• Pelts of the Barbarian: He is clad in a vest made entirely out of gray fur, and — like the archetypical Barbarian — has a brutish personality and fights with a giant club.
• Shout-Out: His armored form is designed after Choukou Senshi Changéríon, which was also written by Toshiki Inoue. He even shares the same character designer (Tamotsu Shinohara) with Changéríon.
• Would Hurt a Child: Any doubts about his villainy are only further quashed when he sends a infant and his stroller into the phantom zone.

The Trio

In General

• 11th-Hour Ranger: They join the Donbrothers in #48 against the Overseers.
• All There in the Manual: The final live tour reveals that their names are actually their second names, and they were named after rulers, their full names are: Claudius Sonoi, Diana Elizabeth Sononi, and Alexander Sonoza.
• Anti-Hero: They aren't above saving humans because their realm actually needs human minds to exist, but once a human becomes too consumed by greed they will not hesitate to eliminate them in order to maintain their "peace".
• Character Development: The trio start off as elite apathetic enforcers hostile to both humanity and its protectors. As the factions fight however, the Noto develop a curiosity towards humanity that the Donbrothers satisfy. The two teams co-mingle and progressivly begin to acknowledge one another, allowing the Trio to develop their own independent personalities and ambitions to the chagrin of their masters. This leads to the Trio being branded as traitors and them joining the Donbrothers as a result.
• The Comically Serious: While the Nōto Trio were initially completely serious until episode 17, they later start to become closer to one of the Donbrothers (Sonoi to Tarou, Sononi to Tsubasa, and Sonoza to Haruka) and thus get into a lot more hilarious situations with their supposed enemies, but they still keep a straight face most of the time.
• Deconstructed Character Archetype: Most elites in evil Super Sentai organizations are Wretched Hives full of seedy backstabbers and toadies with often a singular, honorable exception that (usually) ends up the lead Ranger's rival. The Noto trio however operate under very few of these stereotypes: They're Anti-Villains with varying degrees of honor that also fight the MOTW and protect the populace like the heroes do. The trio all respect each other and never actively betray one another, showing the same kind of teamwork expected out of a Sentai team. The Trio's willingness to communicate and socialize makes them a Friendly Enemy to the team that often get wrapped in their comedic hijinks and share introspective moments with them. Each of the trio becomes The Rival to a ranger (as opposed to a single Rival) and those rivalries spark Character Development. The Trio's primary character-arc during the show's last quarter is centered around whether they should play up to the stereotype of The Dragon or acknowledge their own imperfections and make amends with their enemies. They choose the latter and eventually defect.
• Friendly Enemy: The Nōto initially start off hostile to the Donbrothers due to their clashing methods of neutralizing the Hitotsu-Ki. As the show goes on however, the Nōto's bad blood towards the team vaguely thaws as they pick up on traits and motivations that earn their notice, getting involved in the Donbrothers' hijinks as time passes. Taro and Sonoi grow a pseudo-friendship thanks to their rivalry while Sononi, Sonoza and Don Murasame find themselves enraptured by Tsubasa, Haruka and Jiro's motivations respectively. The factions fraternize almost as much as they fight. However this is shown to have consequences, as new commander Sonoshi is assigned to watch over (and potentially discipline) the primary trio in #37 for their uptick in kindness. The "enemy" part eventually sloughs away in favor of a Hazy-Feel Turn, which gets them marked as enemies by the Council and replaced by Sonoshigoroku.
• Heel–Face Turn: Halfway into the show, the Trio begin warming up to humanity and their supposed enemies; whose influence allows the three to grow out of their "perfection" and into better people. The last straw comes when their Council callously boots them out of Ideon and replaces them with Sonoshi and their darker substitutes, giving the Trio the excuse they need to properly defect to the people they've already grown fond of.
• Humanity Is Infectious: Over the course of their quest to learn about humanity, they come to embody the traits in people that they used to look down on. This culminates in Sonoi finally being able to create a work of art, Sononi understanding what love is after observing Tsubasa trying to rescue Natsumi, and Sonoza understanding human emotions through reading Haruka's manga.
• To Be Lawful or Good: The Trio’s arc throughout the show involves them slowly starting to ask this question. They start off as goons to their Council uninterested in humanity. Then they start fighting the Donbrothers in earnest and by learning about what drives their enemies, discover they have things that drive them too. Episodes 44 and 45 sees the Trio come to a collective Heel Realization that they’re Going Native and, after some wrestling with the idea of Noto pride, choose to be Good - defecting to the Donbrothers instead of letting themselves be executed.
• Villain Takes an Interest: Each of the generals develop a fascination with a member of the enemy team and uses the excuse of "research" to justify talking to them: Sonoi and Taro become friendly rivals, Sononi believes Tsubasa can teach her about love and Sonoza uses Haruka's manga as a tool in his quest for emotions.

Sonoi

Portrayed by: Yuya Tominaga (live), Hirotsugu Mori (suit)

Absolute integrity and perfection incarnate! Sonoi!

Armored form

Kyokatai form

Why would you scatter flowers? Flowers should only scatter in a wind serene. Or fall in quiet, by all unseen.

Skin: Baron Cross

A calm and graceful man who is interested in human art, owning a collection of paintings.

---

• Action Fashionista: Is apparently a fashion leader in his homeworld.
• Affably Evil: Sonoi is more polite and affable towards his foes and is even willing to risk his life and help bystanders. Eventually the Evil part goes away.
• Affectionate Nickname: The owner of the oden cart both factions frequent takes to calling him "Noi-chan."
• Badass Biker: Strolls into fights on a motorcycle.
• Blue Is Heroic: Haruka initially thinks of him as a hero after 'saving' her from Benitsu-ki in his primarily-blue armored form, and in turn, makes her wrongly think she's the 'Taro Momoi' she's supposed to be looking for. He then proceeds to subvert this right in front of her as he brushes her off and kills Shisotsu-Ki (AKA Yoshioka, her own classmate, in cold blood). That being said, he's still more-or-less the Token Good Teammate of the Nōto trio, and has done some genuinely heroic actions like save Haruka from what would otherwise be a fatal blow in order to make up for murdering Taro by exploiting his weakness. However, he then starts to eventually take this role by the end.
• Borrowed Catchphrase: After his revival via absorbing Taro's essence, he begins using the latter's catchphrases such as "Interesting!"
• Came Back Strong: After being revived he's now on par with Taro at the minimum, able to fight him to a standstill and getting the upper hand in their rematch duel.
• Came Back Wrong: Being revived with Taro's energy caused him to obtain Taro's characteristics, including his constant attacking of allies like Taro used to do at the beginning of the show.
• Character Development: Twice. First when he genuinely starts to care about Taro, and then a second time in #44 when he is finally able to create a painting he was satisfied with.
• Cool Sword: In his armored form, he wields the Baron Sword, a powerful broadsword capable of slashing through Hitotsu-Ki like butter.
• The Dog Bites Back: During the Zenkaiger crossover film, Jiro's domineering leadership of the Donbrothers reaches a boiling point and Sonoi rebels, losing and being kicked off the team for daring to question. Later in the film, he re-appears and intercepts Jiro's attempt to attack Taro during the final battle, hospitalizing him off-screen.
• The Dragon: The main enforcer of the Nōto Council and the Arch-Enemy of the red ranger, per Sentai tradition.
• Establishing Character Moment: His second appearance in the first episode. He rides into battle on his bike, and as Oni Sister approaches him to ask if he's Taro Momoi, he kicks her aside right before fighting and finishing off Shishotsu-Ki.
• Expository Pronoun: Sonoi's default personal pronoun is "watashi". After being revived with Don Momotaro's essence in #32, he picks up Taro's habits and switches to "ore". However, after eating oden with wasabi in #34, it's apparently effective enough to make him switch back to "watashi" again.
• Hero Killer: At the end of #13, he strikes down Taro, taking advantage of a moment of weakness.
• Hidden Depths: According to his remark in #18, he is considered a fashionista among the Nōto.
• Klingon Promotion: After defeating Taro in their second duel, he declares that Taro's companions are now his.
• The Leader: Downplayed. While Sononi and Sonoza look up to Sonoi, he rarely gives them any direct orders. After his revival however, he beats Sononi and Sonoza into submission and has them bow down to him. The two start addressing him with the "-sama" suffix from then on. They stop after an oden/wasabi combo returns him to normal.
• Luckily, My Shield Will Protect Me: After reviving, his new chest protector can be used as a shield.
• Likes Clark Kent, Hates Superman: Forms a Commonality Connection with Taro in #8, with both men sharing similar philosophies but initially unaware that they're each other's biggest rival.
• Mirror Character: Invoked after his revival. In his new state, he's a cocky Boisterous Bruiser that sees his colleagues as "companions" - effectively Taro if he were on the side of evil.
• My God, What Have I Done?: Exploiting Taro's inability to lie to strike him down leaves Sonoi appalled at himself. It's such a stain on his personal honor that he protects Oni Sister from a single fatal blow as if it would help to make up for it.
• Not So Stoic: After reverting back to his personality prior to his revival, Sonoi becomes a lot more prone to silly moments, often reacting to the events around him with utter bafflement.
• Occult Blue Eyes: He has deep blue eyes and possesses many abnormal abilities, being able to change humans into Hitotsu-Ki and transform into a blue, eagle-inspired form for starters.
• Perfection Is Impossible: He believes that art is humans' way to show their imperfections, as they are too "primitive" to do better. On the flipside, a perfect being like him can't create anything that is imperfect by default, like art.
• Pragmatic Villainy: To a T. He is not above using any advantage he can get from ambushing his targets to asking Taro about his weakness, knowing he can't lie or dodge the question. However, he's not entirely thrilled with acting like that, even if he'll do it to get a win. After he exploits Taro's weakness to "kill" him he feels like he acted disgracefully in doing so and even feels the need to make up for it, which he does by saving Haruka from a similar fate of getting ambushed by Sononi. But only once, as he feels he paid the debt with that and won't save her a following time. After Taro's return Sonoi decides he isn't willing to fight like that after all because he finds it disgraceful. When he attempts a fair rematch against Taro and Taro drops his transformation and leaves himself open because he refuses to fight him, Sonoi stops his sword and refuses to cut him down when he's vulnerable again.
• Proper Tights with a Skirt: A reconstructed variant. He wears shorts over leggings, but it isn't obvious as they're both made of the same material and color.
• Red Eyes, Take Warning: After being revived he sports red eyes, and Came Back Wrong by acting like a dark version of Taro instead.
• Red Oni, Blue Oni: Amusingly for the series' theme, he's the Blue to Taro's Red.
• Rule of Symbolism: Sonoi starts the show unable to produce anything resembling art. Near the end of the show, he produces an adequate painting, demonstrating that he's outgrown his Creative Sterility.
• Shout-Out: His armored form is designed after Choujin Barom 1.
• The Stoic: He mantains a serious demeanor even when exposed to Sonoza's laugh or facing the train wreck that is the Donbrothers. Hanging out with Taro brings out some surprisingly soft expressions from him, though. His revival in episode 32, however, flips his stoic switch the other way, and he becomes pretty much Don Momotaro in all but name.
• Super Mode: After being restored to his original personality, he can use his Kyokatai form as this, preferring to use his default Transformed form instead for the most part.
• Symbolic Wings: Decorated on his armored form's helmet.
• Token Good Teammate: Sonoi is probably the most approachable of the Nōto. He's more willing to actively jump in and help other people than his colleagues and the respect he has for Taro's civilian persona is genuine. Even with an honor code as a makeshift conscience, he's still dismissive of humans at best and can be just as ruthless as his colleagues.
• Took a Level in Jerkass: His taking on Taro's personality upon his revival, causes him to start being rude and dismissive of Sononi and Sonoza as merely his "Companions" the same way Taro is to Donbrothers, even kicking Sononi and Sonoza about in #33 in the same vein Taro did to the others after the show's early battles. It doesn't take and he eventually stabilizes.
• Trademark Favorite Food: Oden after Taro introduces him to it.
• Tsundere: He's normally quite soft with Taro, even after finding out that Taro's his enemy. However, his revival with Taro's juice makes him rather abrasive to most people, especially Taro. It doesn't last long, though, as eating wasabi with oden in #34 somehow magically returns his original personality and he's back to being "deredere" to Taro again.
• Uncertain Doom: In the crossover film, Sonoi extracts the essence of Taro that the Council planted in him and returns it to the latter after they've seemingly died. He then stops Jiro from attacking Taro during the final act and battles him off-screen. Sonoza finds him unresponsive in his oden stand during the credits, his final fate left open.
• Villain Respect: Sonoi develops an admiration for the naïve purity of Taro's civilian persona and a more begrudging respect for his powerful Donbrother guise, unaware they're one and the same at first.
• Villainous Rescue: In Episode 15 he reveals to the Donbrothers that Taro is sleeping in another dimension and provides them with the means to by "slaying" Tsuyoshi and letting Jiro be transported to said dimension alongside him so that they could bring Taro back.
• Villainous Virtues: Cares about saving people (moreso the "saving") and adheres to some sort of honor code. His murder of Taro in #13 leaves him deeply ashamed.
• We Can Rule Together: He thinks Don Momotaro would make a "good servant." Momotaro responds by saying he'd make a "terrible companion."
  • In 33, he and the generals arrive at Cafe Donbura to "recruit" the Donbrothers as Noto reserves.

Sononi

Portrayed by: Amisa Miyazaki (live), Yuichi Hachisuka (suit)

A beautiful rose has its thorns... Looking to know love, Sononi!

Armored form

Why is it that men and women fall in love? They say love is precious... But I don't understand the meaning of it.

Skin: Coron Dress

A woman who is curious about romance in the human world.

---

• Back from the Dead: She briefly died from major injuries in episode 44, before Tsubasa used his Kibi-Points to revive her.
• Bare Midriffs Are Feminine
• Bifurcated Weapon: Her Condor Arrow can be broken into twin blades and vice-versa.
• Character Development: Sononi had the longest development of the main Noto trio ever since she met Tsubasa, having first experienced true love in #40 and fully understanding it by #44, making her the first Noto to fulfill their character development.
• Dark Action Girl: An unassuming young woman that can easily dispatch anybody that doesn't fulfill her ideal of beauty. Eventually she leaves this role and becomes an Action Girl.
• Devoted to You: Becomes this to Tsubasa after falling in love with him till the point she attacks the police to prevent him from being arrested, which also causes her to be labeled a criminal.
• Establishing Character Moment: She makes an entrance by shielding Kaitou-ki from the Donbrothers' Finishing Move, yet afterward turns around and shoots the poor Hitotsu-ki in the back after considering him no longer beautiful.
• Faux Affably Evil: She makes herself to be a mysterious, somewhat kind figure that seeks out beauty in creatures that she finds interesting. If they don't fulfill her standards of "beautiful", she dispatches them in a heartbeat. Later on, she tends to shift between this and Affably Evil as far as her interactions with Tsubasa is concerned.
• Icy Grey Eyes: Has grey eyes and was arguably the most ruthless of the generals with her Faux Affably Evil disposition before her development.
• Light Is Not Good: Is dressed in white, and is one of the series' major villains. Her armored form is also primarily white. However, Character Development kicks in and she subverts this.
• Outlaw Couple: At the end of the series, she's now dating with Tsubasa and they're both on the run from the police.
• Perpetual Frowner: Her default expression. She is often seen with a dull scowl on her face.
• Pet the Dog: In an almost literal example she's clearly grown fond of Tsubasa after a while and he's the only Donbrother she approaches without hostility. Sononi even starts acting downright nervously shy around him in some cases. When he becomes possessed by Murasame's sword she even comes running to his aid and gets possessed herself trying to save him. She even ends up falling in love with Tsubasa and sacrifices his rapport with her to prevent her lies from getting Miho and Natsumi inadvertently killed by his hands.
• Second Love: For Tsubasa.
• Shout-Out: Her armored form is designed after Seigi No Symbol Condorman.
• The Smurfette Principle: The sole female member of the primary Nōto general trio until her Character Development kicked in.
• Taking the Bullet: Almost three times, two of them within minutes of each other in the same episode.
• The Straight and Arrow Path: Primarily fires energy bolts from her Condor Arrow bow, which can also be split apart into twin swords.
• Swiss-Army Weapon: Her Condor Arrow is a bow that can split into two swords.
• Villain Takes an Interest: She is intrigued by Tsubasa's love for Natsumi. In #40, she ends up falling for Tsubasa instead.
• Villainous Virtues: She is capricious, vain and has no problem with protecting Hitotsu-Ki from Donbrothers just so she could shoot them herself, but genuinely cares about her co-villains.
  • #14 shows that Sonoi's confusion and distress over slaying Don Momotaro worries her even if she doesn't understand why it would.
  • She is shown to keep promises, as she was willing to help Tsubasa with his wish because she lost a bet to him.
    • In addition, after learning of Tsubasa and Natsumi's story she feels genuinely concerned over them.
• What Is This Thing You Call "Love"?: She's intrigued by why and how humans fall in love with each other, desiring to know what love means.
• Yandere: By the end of #40, she shows signs of this towards Tsubasa when she tells the latter that killing the Crane Juto will 'free' Natsumi while deliberately leaving out the part where Natsumi will die if he does that with her eyes glowing sinisterly after that. Unlike most examples, however, she almost immediately recognizes the consequences of her actions, and ends up stopping the outcome from happening halfway through.
• You Are Worth Hell: In the final arc, she willingly attacks the police in defence of Tsubasa, choosing to become a fugitive so to stay by his side.

Sonoza

Portrayed by: Shinnosuke Takahashi (live), Riichi Seike (suit)

When my interest is caught, nothing gets in my way! Sonoza!

Armored form

Why do they laugh? The humans. What even is it?

Skin: Kage Style

A creepy man with disarranged emotions inappropriate for every moment, he is interested in human emotions.

---

• The Brute: He serves as the muscles of the Nōto.
• Character Development: Sonoza's Inhuman Emotion tendencies die out as the show progresses, with him having moments of natural quirkiness here-and-there. He starts #44 off with happy tears flowing down his face and in the Zenkaiger crossover film, delivers an emotional Rousing Speech at Taro's funeral.
• The Comically Serious: His completely straight-laced demeanor as he tries to understand human emotions is a primary source of comedy.
• Hidden Depths: He loves manga, particularly Haruka's, which allows him to have an extensive knowledge on various cliche plots and tropes. As such, he inadvertently becomes Haruka's editor despite being her enemy.
• Inhuman Emotion: He desires to know more about human emotions. As such, he constantly expresses the wrong emotion for the mood of any situation - often in the creepiest way possible. Eventually grows out of it and displays more proper emotions at reasonable levels thanks to Haruka.
  • His reaction to getting hit in the face with a rock in #14 is to let out a deadpan ouch and then start laughing.
• Pragmatic Hero: Sonoza thinks Sonoi's stealth-murder of Taro was a "valid tactic" hardly worthy of shame.
• Prima Donna Director:
  • Or in this case, "Prima Donna Editor". He extensively criticizes Haruka's work in #21 and #22 for being contrived and bland, which doesn't spark anything in his heart. As such, he rejects most of her attempts, which causes Haruka to fume at his behavior. He warms up to her writing style as time goes on and eventually makes it his dream to see the girl's manga career get off the ground.
  • By contrast, he's said to be much worse about this in Naoki Shiina's timeline, his antagonism having made enemies out of his timeline's Haruka and Saruhara.
• Rousing Speech: He's the one to re-motivate the team after their 10-Minute Retirement and Taro's following death at the hands of Kikai-Ki in the crossover film, encouraging them to avenge him.
• Shout-Out: His armored form is designed after The Kagestar.
• Supernatural Gold Eyes: Possesses amber eyes and has the same strange abilities as his fellow generals.
• Villainous Virtues: He is a creepy brute with Blood Knight tendencies, but respects his co-villains and Sononi has recruited him to help her look after Sonoi in past.
• Villain Takes an Interest: Downplayed. Sonoza isn't interested in Haruka but the manga she writes, thinking it can help in his quest to discover emotions.
  • Later when he meets Haruka during Sonoi's attempt to claim the Donbrothers to serve him, Sonoza is quick to notice Haruka has been trying to draw manga and encourages her to keep trying to push past her slump.
• Well-Intentioned Extremist: Sonoza's kidnapping of Haruka in episodes #21 and 22 is solely in the hopes that her manga can fuel his quest for emotion. He's a harsh critic but never directly threatening.
• When He Smiles: His genuine laugh and smile in #44 are very natural in contrast to his previous attempts at smile and laughter.
• The Worf Effect: His fights with Don Momotaro often end with him on the losing side, despite being able to take down the other Donbrothers quite easily. This is probably explained by the experience gap between Don Momotaro and rest of the team because without him, they are hopelessly outmatched.

Soldiers

Anōni

Portrayed by: Various

The footsoldiers of the Nouto. While normally blending in as ordinary humans, the Donbrothers' sunglasses are able to see through their disguises.

---

• Affably Evil: When they kidnap Haruka's aunt as ransom for the Donbrothers' help, they're polite to just about all parties; pampering Yuriko during her stay and even paying their bar-tab at the cafe. Even Taro notes how nice they were being.
• Mook: They're soldiers that work for the Nōto.
• Punch-Clock Villain: While they do fight the Donbrothers, they generally tend to keep to themselves for the most part, and are even willing to ask for their help to deal with the Jūto - though they resort to kidnapping Haruka's aunt to secure their cooperation.
• Punny Name: Their name is a portmanteau of "anon" (as in anonymous, referring to their ability to blend in with the general population), and the Japanese phrase for "That Oni"/Ano Oni.
• They Look Just Like Everyone Else!: Normally they look like ordinary humans. Only the Donbrothers' sunglasses can see through their disguises.
• Wild Card: They primarily serve the Hitotsu-Ki, but once a general enters the field, they loyally bow their heads to the latter instead. #29 has Anoni attendants serving the Nōto too.
• You Can See Me?: One of them has this reaction to Haruka in the first episode when he's revealed by her new glasses.

Hitotsu-Ki

More! I need more!

Monstrous oni forms taken on by humans with extreme desires in their hearts, gaining the power to wreak havoc in both the human realm and the Nōto Layer. They are the targets of both the Donbrothers and Nōto, the former to rescue the human that became them and the latter to execute for their disruption of the Nōto Layer.

General Tropes

• Colourful Theme Naming: Basic Hitotsu-Ki with no specific motif are named based on their color.
• Cruel and Unusual Death: Death at the hands of a Nōto is not pretty; those killed this way have their souls trapped in a cube in dimensional space as it breaks and shatters into a million pieces. All while the victim screams in pain the entire time.
• Demonic Possession: Shown in multiple instances, the "power" to become a Hitotsu-Ki manifests as a "ghost" that gets attracted to a human's strong desire and then possesses them to gain a solid body, hence their Meaningful Name. As such, they can also change their hosts via various methods (natural and forced) as well.
• Face–Monster Turn: All Hitotsu-Ki are humans warped into hostile abominations by their own desires. Most of them are people succumbing to stress rather than bad actors.
• Goal-Oriented Evolution: They are humans evolved through having an extreme desire to achieve their goals.
• Killed Off for Real:
  • Zigzagged with the ones eliminated by the Nōto, as Jiro and Tsuyoshi discover a prison full of people they've eliminated. Those whose cubes are cracked at the time of its destruction, however, are gone for good.
  • Averted with the ones defeated by the Donbrothers. Defeating them after their evolution into Hitotsu-Kings reverts them back to their original human forms.
• Make My Monster Grow: Via evolution. Certain Hitotsu-Ki defeated by the Donbrothers will evolve into a giant, more advanced version of itself known as a Hitotsu-King.
• Madness Mantra: They have a tendency to constantly repeat the major hangup that caused them to transform into the Hitotsu-Ki in the first place.
• Meaningful Name: Literally means "Human-Latching Demon".
• Mix-and-Match Weapon: Most of them wield some form of combined weaponry, usually an iron club with a cleaver blade running along it's length.
• Monster of the Week: They are the monsters the Donbrothers have to face every week.
• Mythology Gag: Their Hitotsu-King forms are themed after previous Sentais' main Combining Mecha, and as such also follow the Theme Naming of "[Insert Theme]-King" much like how the more recent Giant Mecha are commonly named "[Insert Theme]-Oh/King".
• Phantom Zone: Hitotsu-Kings are able to extract the Nōto Layer from their immediate landscape to become one that floats in the skies above; only destruction caused the Hitotsu-King to the area will damage the landmark it represents in real-life.
• Serious Business: Some of the Hitotsu-Ki's host desires are some rather mundane activities which they took very seriously such as sports, games, arts, etc...
• Transhuman: They evolve naturally from certain humans with strong desires, although the Nōto are able to induce a forced evolution from their human forms as well.

Hitotsu-Ki types

Benitsu-Ki

Portrayed by: Unknown

Skin: Crimson Color

A crimson type Hitotsu-Ki evolved from an unnamed taxi driver, to fulfil his desire for destruction.

---

• Colourful Theme Naming: Is named after the Japanese term for crimson, beni-iro.
• Sacrificial Lamb: His death, alongside Shisotsu-Ki's later in the first episode, shows the consequences of what happens if the Monster of the Week for this series dies at the hands of any of the Nōto.
• We Hardly Knew Ye: He didn't last long before getting eliminated by Sonoi.

Shisotsu-Ki

Portrayed by: Yusuke Yatouji

Skin: Perilla Color

A purple type Hitotsu-Ki evolved from Haruka's classmate Yoshioka, to fulfil his desire to become stronger at table tennis.

---

• Colourful Theme Naming: Is named after the Japanese term for "perilla color", shiso-iro, specifically referring to the purple color some variants of the plant are.
• Killed Off for Real: He gets erased by Sonoi right in front of Haruka. Ultimately subverted in episode 46, where he's shown as one of the freed Hitotsu-Ki hosts.
• Sacrificial Lamb: Like Benitsu-Ki before him, his death at the hands of Sonoi shows the consequences of letting any of the Nōto kill a Hitotsu-ki instead of the Donbrothers purifying them on time. Notably, he's also the first named human-turned-Hitotsu-Ki to die for real.

Kishiryu-Ki

Portrayed by: Masanari Kanou

Skin: Knight's Armor (Hitotsu-ki), Three Knights' Armor (Hitotsu-King)

A knight-themed Knightosaur type Hitotsu-Ki evolved from former table tennis gold medallist Makoto Kasuga, to fulfil his desire to prove he is the best.

---

• Early-Installment Weirdness: He's the only one that Sonoi actually transforms into a Hitotsu-Ki, implying that the Nōto have some form of control over them. However, as the story continues, this is further from the truth since the Nōto want to kill any Hitotsuki they come across and all of the Hitotsuki made afterwards occur on their own (with very rare exceptions), leaving Kishiryuki to be an oddity.
• Madness Mantra: As Kishiryu-King.
  "Bronze medal, silver medal, gold medal. Bronze medal, silver medal, gold medal...!"
• Shout-Out: Along with the aforemention Ryusoulger shoutout, his Hitotsuki form resembles the armor of the "Knights of Rafkon" from Power Rangers Dino Fury.

Ressha-Ki

Portrayed by: Sachiko Matsura (main); Sanae Yūki (age 40); Momoka Kuroki (age 20)

Skin: Steam Locomotive (Hitotsu-Ki), Steam Locomotive: 9-length Train (Hitotsu-King)

A steam engine-themed Blaze Train type Hitotsu-Ki evolved from Taro's colleague Sanae Isono, to fulfil her desire to regain her youth.

---

• Madness Mantra: Has two of them.
  "More younger! Younger!"
  "How old do I look... how old do I look...!?"
• One-Winged Angel: Her Ressha-King form resembles a giant monster train based off the Shadow Line trains.

Kaitou-Ki

Portrayed by: Shutaro Kadoshita

Skin: Arsène Cloak

A phantom thief-themed Flash Thief type Hitotsu-Ki evolved from a thief known only as Kurokuma^note "Black Bear", to fulfil his desire to steal all lights and bring darkness to people.

---

• Asshole Victim: Unlike the other Hitotsu-Ki, he's much less sympathetic, but it doesn't make his sudden death at Sononi's hands any less shocking.
• Evil Knockoff: To Taro and his delivery company Shirokuma^note "White/Polar Bear". He disguises himself as a courier with a fake company Kurokuma to break into peoples' homes, while his catchphrase knocks off Taro's own.
  "I don't carry packages. I carry darkness."
• Freudian Excuse: Shinichi theorizes that the various abuses that he faced on the job caused him to spiral and decide to steal lights, hoping to steal people's happiness just like they did.
• Imposter Forgot One Detail: Taro was able to figure out he was the thief, due to noticing that the cargo of his truck hasn't changed at all since last night along with how sloppily the packages are packed.
• Killed Off for Real: He gets erased by Sononi, subverting his potential Make My Monster Grow into Kaitou-King as well. Ultimately subverted in episode 46, where he's shown as one of the freed Hitotsu-Ki hosts.
• Only Known by Their Nickname: His real name was never revealed and is thus only known by his thiefname "Kurokuma".
• Phantom Thief: As per his inspiration, his armored form resembles a monstrous Lupin-like figure, complete with his face looking like the Lupinrangers' emblem.

Chouriki-Ki

Portrayed by: Kizuki

Skin: King's Pyramid

A pyramid/pharaoh-themed Superpower type Hitotsu-Ki evolved from chef Yukio Mizuno, owner of the onigiri store Onigiri Gorogoro, to fulfil his desire to make a perfect 100-point score onigiri that satisfies Taro.

---

• Despair Event Horizon: Gets pushed beyond it when Taro rates him as Always Second Best to himself (with the skills to back up his claim). Despite being adviced by Taro on how to make the best onigiri, his utter disappointment in himself causes him to evolve into Chouriki-Ki and go on a rampage.
• To Be a Master: His obsession stems from wanting to be the best in onigiri-making.

Keisatsu-Ki

Portrayed by: Ryoji Sugimoto

Skin: Hot-Blooded Officer (Hitotsu-Ki), Good Patrol Car (Hitotsu-King)

A bulldog/police officer-themed Police type Hitotsu-Ki evolved from officer-detective Kenji Sayama, to fulfil his desire to gain enough credit to be given a Superintendent's Commendation before his upcoming retirement.

---

• Came Back Wrong: Was one of the forty-one passengers who disappeared when their bus went into a tunnel. He's later shown alive in a ramen bar, only to attack the patrons while sloppily eating some meat and showing off fangs.
• Cowboy Cop: While his desire has some noble intentions, becoming a Hitotsu-Ki drives him to also intend to personally execute his target criminals, even if he doesn't have the proper authority to do so.
• Hand Cannon: Wields a rather large pistol in battle.
• Knight Templar: His desire to pursue justice has distorted enough to the point he became a Hitotsu-ki and was willing to even execute his targets.
• Weaponized Headgear: Keisatsu-King's hat has a gun mounted into it, giving him both the Patkaiser look and allowing him to shoot relentlessly at Don Zenkai-Oh.

Doubutsu-Ki

Portrayed by: Hitomi Uneda

Skin: Animal Collection

A zoo monument-themed Animal type Hitotsu-Ki evolved from a nurse named Kirita, to fulfil her desire to save every patient herself.

---

• Knight Templar: Similar to Keisatsu-Ki, her desire to save patients gets twisted to the point of willingly harming civilians in order to supply herself with "patients" to save.
• Threatening Shark: Her head resembles a Great White as part of one of the original 5 Zyuoh animals.

Chikyuu-Ki

Portrayed by: Daifuku Marui

Skin: Earth Tector (Hitotsu-Ki), Max Volcano (Hitotsu-King)

A globe-themed Earth type Hitotsu-Ki evolved from the principal of Tsunokaku High School, where Haruka studies, to fulfill his desire to make others learn discipline.

---

• Invisibility: He has the ability to become invisible.
• Knight Templar: Wants to instill discipline in people, but gets distorted into trapping rule-breakers within pieces of paper that he can then burn down as punishment.
• Magma Man: Can launch magma from his head as Chikyuu-King, referencing the fact that said form is based on Max Magma (which ironically did not have magma-based powers in its home series).
• Spotting the Thread: Don Momotaro was able to find him even though he was concealed, due to the fact that his hay fever at the time causes him to sneeze from the pollen the former scatters from his fan.

Mashin-Ki

Portrayed by: Junpei Shimada

Skin: Sparkling Mage

A gemstone/mage-themed Magic Vehicle type Hitotsu-Ki evolved from Sakaki, a long-haired vagrant artist, to fulfil his desire to draw his ideal model.

---

• Asshole Victim: Arguably more deranged than Kaitou-Ki and the first Hitotsu-Ki one of the DonBrothers wrote off as a lost cause, but just like the latter, you can't help but feel a little bad for him, especially when Don Momotaro was very close to saving him.
• Beyond Redemption: Kiji Brother considers him this for hurting his wife, and intervenes with Don Momotaro's finisher so Sonoi can kill him off for good.
• Killed Off for Real: Is slain by Sonoi after Kiji Brother stops Don Momotaro's finisher, with Kiji Brother letting him die for daring to hurt his wife. Ultimately subverted in episode 46, where he's shown as one of the freed Hitotsu-Ki hosts.
• Mad Artist: Is driven insane by his desire to find the ideal model, leading him to become a Hitotsu-Ki.
• Traumatic Haircut: A variation - Miho exploits his long hair to give him a haircut, which allows her to escape from him... and for him to finally turn into a Hitotsu-Ki.

Tokumei-Ki

Portrayed by: Ouga Tsukao (child), Bunmei Harada (old)

Skin: Buddy Cheetah

A cheetah-themed Special Ops type Hitotsu-Ki evolved from the spirit of a hospitalized old man named Taichi Izawa, to fulfill his desire to play games with everyone.

---

• All of the Other Reindeer: The core of his desire is due to the fact that he's shown to have a lonely childhood, having been ostracized by other kids whenever he tried playing games with them. His old age at present and the fact that he's been hospitalized implies his childhood desire went berserk as a form of a Last Request.
• Anti-Villain: Has quite possibly the least malicious motivation of any Hitotsu-Ki up until his debut, simply being an old man's childhood desire to have fun playing games with other people. He doesn't even seem aware that his actions are endangering anybody he plays with.
• Intangibility: Due to having evolved from his spirit rather than his physical body, his Hitotsu-Ki form is not physical, making him hard to damage.
• Teleport Spam: The last stage of his game with the Donbrothers has him randomly teleporting around as he counts down, making it almost impossible to tell where he'll be once he stops.

Kaizoku-Ki

Portrayed by: Yuji Kubo

Skin: Pirated Pirate

A pirate/octopus-themed Pirate type Hitotsu-Ki evolved from a failing manga artist named Naruki Oi, to fulfil his desire to become a manga artist.

---

• Cannibalism Superpower: He absorbs other mangaka in order to steal their talents to make up for his lack of it.
• Combat Tentacles: Uses them to abduct his targets or to attack.
• I Just Want to Be Special: He is an avid fanboy of mangakas whose desire to become one despite his lack of talent led him to evolve into a Hitotsu-Ki.
• Shout-Out: His octopus design along with his pirate motif is one to Davy Jones.

Shuriken-Ki

Portrayed by: Takashi Sakakibara

Skin: Ninja that Doesn't Hide

A ninja-themed Shuriken type Hitotsu-Ki evolved from a ninja wannabe named Minoru Ohno, to fulfil his desire to show off his ninja skills.

---

• Caltrops: Can summon some in combat, which Kiji Brother has the ill fortune of stepping on.
• Fuuma Shuriken: Uses two, stored on his head and chest, in combat.
• Let's See YOU Do Better!: His evolution came about as a result of wanting to prove his ninja skills to an unimpressed Taro.
• Me's a Crowd: Can create Shadow Clones of himself in battle.
• Strong And S Killed: Compared to other Hitotsu-Ki, Shuriken-Ki also has the skills to back up his powers and abilities allowing him to give Taro trouble without the other Donbrothers backing him up.

Uchu-Ki

Portrayed by: Wataru Oguri

Skin: Ultimate Planetarium (Hitotsu-Ki), All-star Constellation (Hitotsu-King)

A celestial sphere-themed Space type Hitotsu-ki evolved from a young idol fanboy, to fulfil his desire to monopolize all idols.

---

• Giant Space Flea from Nowhere: Uchuu-Ki had virtually no connection to the overarching plot of the episode it appeared in (aside from a tangential plot involving kidnapping idols), but nonetheless appeared to provide the requisite battle of the episode.
• Mythology Gag: Apart from his theme, he does the hip thrusts found in the first version of Kyuranger's ending Dancing Theme after turning into Uchuu-King.
• Terrain Sculpting: As Uchu-King, he creates an elevated platform in the midst of his battle against Don Onitaijin.
• We Hardly Knew Ye: Hardly anything is known about him aside from his motives, even as Uchu-Ki he hardly displays any unique powers.

Zyuden-Ki

Portrayed by: Fukiko Hara

Skin: Brave In Mask (Hitotsu-Ki), Almighty Dino King (Hitotsu-King)

A tiki mask-themed Beast Power type Hitotsu-ki evolved from the town's claimer Fusako, to fulfil her desire to be cared for.

---

• Attention Whore: Her desire to be noticed and be cared for leads her to commit various attention-seeking acts such as making a scene at Donbura and at a department store.
• Dance Battler: Downplayed; she uses samba rhythms in battle but prefers to shock her foes instead.
• Shock and Awe: Mainly releases blasts of electricity as her weapon.
• Tragic Villain: Her desire stems from the fact that her husband had passed away and her only child left home, leaving her all alone with no one to care for her.

Kousoku-Ki

Portrayed by: Yasumasa Ishida

Skin: Shogi Piece GT (Hitotsu-Ki), Turbo Custom Car (Hitotsu-King)

A shōgi-themed High-Speed type Hitotsu-ki evolved from a high-school student and shōgi player, to fulfil his desire to become stronger at shōgi.

---

• Forced Transformation: Anyone struck by his Eye Beams gets turned into shōgi pieces.
• Freeze-Frame Bonus: If one looks closely and can understand Japanese, you can see he attends Musashino Academy, possibly lending an in-universe explanation for his motif.
• Mythology Gag: One of his special attacks begins with him being flanked by four shōgi pieces in a manner similar to that of the Turborangers' team pose.
• Super-Speed: Can blaze about the battlefield in quick bursts.

Gekisou-Ki

Portrayed by: Hirofumi Suzuki

Skin: Full Accel Salaryman

A car-themed Extreme Rush type Hitotsu-ki evolved from Pheasant Consultant employee and Donbrother Tsuyoshi Kijino, to fulfil his desire for revenge against those who hurt his wife Miho.

---

• And Then John Was a Zombie: Gekisou-Ki is none other than Kiji Brother, maddened by his desire to avenge his wife, and ends up fighting against the other Donbrothers.
• Critical Existence Failure: Can literally delete vehicles and cars from the road.
• Madness Mantra: "Trafficsafetytrafficsafety... TRAFFIC SAFETY!!"
• Mythology Gag: His favored method of attack is to spin rapidly while striking his enemies with a sword, evoking RV Robo's Finishing Move.
• Necktie Headband: As part of his partially salaryman-inspired design.
• Spin Attack: Employs a lot of these defensively.
• Single-Issue Wonk: Miho being nearly hurt by a vehicle has Tsuyoshi concerned with removing vehicles from the road to enforce "traffic safety."

Kyoryu-Ki

Portrayed by: Ryuya Minato

Skin: Fossil That Leapt Through Time (Hitotsu-Ki), Tyrannosaurus (Hitotsu-King)

A fossil-themed Dinosaur type Hitotsu-ki evolved from a young gamer, to fulfil his desire to overwhelmingly clear his video game.

---

• Critical Existence Failure: Can delete people the same way Gekisou-Ki could vehicles.
• Cyberbullying: Kyoryu-Ki's host is mercilessly bullied for being bad at the game he's streaming, which becomes the impetus for his transformation.
• Dem Bones: Appropriately enough, for a fossil-themed Hitotsu-Ki.
• Giant Space Flea from Nowhere: Like Uchu-Ki before him, he has no relation to the plot of the episode he appears in, only serving to be a victim of Jiro's Misplaced Retribution.
• Misplaced Retribution: Jiro attacks and defeats him under the assumption that he's the one who caused him to go Brainwashed and Crazy, when in actuality it's Jiro own Split Personality issue with a Superpowered Evil Side.

Choujin-Ki

Portrayed by: Yuka Kohinata

Skin: Birdonic Wing (Hitotsu-Ki), Agile Garuda (Hitotsu-King)

A bird-themed Birdman type Hitotsu-ki evolved from Kanako, the ex-girlfriend of a young man named Makoto Tanabe, to fulfil her desire to seek her fated love.

---

• Bait-and-Switch: Much of the episode it appears in heavily indicates that Makoto would become it due to carrying its potential and his apparent obsession over Kanako fueling it, however as it turns Kanako herself ended up becoming its actual host, due to her own obsession over Tsubasa fueling it.
• Broken Pedestal: The Despair Event Horizon that pushes her to become a Hitotsu-Ki is the very sight of Tsubasa transforming into Inu Brother, being utterly shocked at the apparent Wrong Assumption that her crush turns into or was a "dog" all along.
• Love at First Sight: She fell for Tsubasa when he came to rescue her from Chikyuu-ki right as her then-boyfriend Makoto ran in fear.
• Love Makes You Crazy: Her infatuation with Tsubasa leads her to plaster her room with his "Wanted" poster, and she turns into a Hitotsu-ki after seeing him transform into Inu Brother.

Engine-Ki

Portrayed by: Ai Chushin

Skin: Engine Soul (Hitotsu-Ki), Tuned-up Engine (Hitotsu-King)

A Hitodama Light-themed Engine-type Hitotsu-ki evolved from a ghost named Minako Sagiyama, to fulfil her desire to meet her pen-pal and crush, Shinzo Tadokoro.

---

• Intangibility: Like Tokumei-Ki, physical attacks simply phase through her, due to her having evolved from a ghost.
• Playing with Fire: Can conjure fireballs that she hurls at the enemy.
• Punny Name: Her Hitotsu-Ki name is a play on "engine" and enjin (炎神, "flame god").
• Super-Speed: Can zip around the battlefield in short bursts, courtesy of the engines in her shoulders.
• Unfinished Business: Refuses to pass on until she's met Shinzo.
• Wrong Context Magic: Being evolved from a ghost, a lot of the normal Hitotsu-Ki conventions don't apply to her.
  • She has intangibility, implied to be a stronger variant than Tokumei-Ki's.
  • She is able to invoke Make My Monster Grow without being defeated first.
  • Even while fighting Don Onitaijin as Engine-King, she's able to project a separate body to finish her last moments on the phone with Shinzo before passing on.

Gosei-Ki

Portrayed by: Shigeki Itō

Skin: Pigtailed Fist Fighter (Hitotsu-Ki), Pigtailed Weapons Fighter (Hitotsu-King)

A Chinese dragon-themed Five Star-type Hitotsu-Ki evolved from a man seeking strength named Ashida, to fulfil his desire to fight strong opponents to get even stronger.

---

• Blood Knight: Ashida's sole desire is to constantly fight strong enemies.
• Giant Space Flea from Nowhere: His appearance has nothing to do with the episode's core plot again, like with Uchu-ki and Kyoryu-ki.
• Tantrum Throwing: Gosei-Ki's defeat at the hands of Don Torabolt ends in its host flailing madly on the ground, complaining about his inability to fight.
• Walking Shirtless Scene: His human guise is first seen wearing only shorts. In the rain.

Samurai-Ki

Portrayed by: Yuta Yamazaki

Skin: Word Warrior

A Musha-themed Samurai-type Hitotsu-Ki evolved from Shirai, a former ramen chef and the previous Saru Brother, to fulfil his desire to know his successor Shinichi's reason for fighting selflessly.

---

• Evil Cannot Comprehend Good: Or in this case, "Greed Cannot Comprehend Asceticism". Shirai's desire and failure to understand why Shinichi wouldn't use his powers for self-gain turns him into a Hitotsu-Ki.
• Serious Business: Ramen, so much so that he was willing to forge a signature of the Matsui Clan leader's favorite actor just to get a pot of their tare.
• Symbol Motif Clothing: His armor is littered with various kanji related to "evil". Some of them seen are 悪/aku/"evil" (on his helmet), 死/shi/"death" (on his face), 罪/tsumi/"sin" (on his collar) and 邪/ja/"wicked" (on his torso).
• With Great Power Comes Great Perks: Shirai used his time as Saru Brother solely for personal gain, using it to win athletic competitions, impress the ladies, and cut in line at events, which was why he never became a full Donbrother.

Denji-Ki

Portrayed by: Tet Wada

Skin: Digital Surfer (Hitotsu-Ki), Galaxy Mecha (Hitotsu-King)

A jellyfish/plasma globe-themed Electromagnetic-type Hitotsu-Ki evolved from a wealthy man named Kentaro Goda, to fulfil his desire to listen to an interesting story that will alleviate his boredom.

---

• Cool Board: He rides on one as a homage to the Megarangers' Cyber Sliders, though this may be part Personality Powers as he is shown to be an accomplished surfer.
• Electric Jellyfish: He's themed on a jellyfish, and his powers revolve around electromagnetism.
• Power Copying: He is able to copy the "powers" or summon appliances, which appear as an image in the dome on his head.
• Rich Boredom: A wealthy man who feels he's gained everything, he turns into a Hitotsu-Ki out of sheer boredom.

Juken-Ki

Portrayed by: Shogo Amo

Skin: Master Kung-Fu (Hitotsu-Ki), Radical Fighter (Hitotsu-King)

A jaguar/kung-fu-themed Beast Fist-type Hitotsu-Ki evolved from a student named Tamaru, to fulfil his desire to silence everyone so he can study for his exams in peace.

---

• Berserk Button: Any kind of noise that breaks his concentration/distracts him was the catalyist needed to turn him into the berserking Juken-Ki.
• Cat Folk: His Hitotsu-ki form is an anthropomorphic jaguar, an homage to the main three Gekirangers' animal motifs.
• Combat Hand Fan: Dual Wields a pair of them as Juken-King.
• Crunchtastic: He sometimes lapses into made-up words such as "shouty-shout", like Jan did.
• Freeze-Frame Bonus: His civilian shoes are branded with SCRTC, the sports company that backs the Gekirangers.
• Madness Mantra:
  "Too loud!"
  "I need more quiet!"
• Mythology Gag: One of the most riddled amongst the Hitotsu-Ki, aside from his SCRTC brand shoes, pun-based motives and crunchtastic Buffy Speak based on Jan's, he even quotes the series' Opening Narration, twisted to describe his motives in studying.
• Pungeon Master: His motives are all puns of central terms in Gekiranger — "exam-taking" is homophonous with Juken/"Beast Fist", while "[the] Constitution" (the topic he is studying) is homophonous with Kenpo/"Fist Arts".

Ninja-Ki

Portrayed by: Yoshinari Oribe

Skin: Hidden Ninja (Hitotsu-Ki), Novice Ninja (Hitotsu-King)

A shinobi-themed Ninja-type Hitotsu-Ki evolved from Koichiro, the runaway son of Tomoko Higashi, to fulfil his desire to find meaning in his life.

---

• Contrived Coincidence: The Hitotsu-Ki just happens to be the estranged son of the woman the Donbrothers have been trying to help by having Taro pose as her son.
• Desperately Looking for a Purpose in Life: His obsession for this is main reason he became a Hitotsu-Ki.
• Madness Mantra: "A reason to live...!!"
• Stock Ninja Weaponry: He's armed with a pair of kunai.

Dai-Ki

Portrayed by: Kotaro Taki

Skin: Rhythmic Gymnastics Ruins (Hitotsu-Ki), Ribbon Competition (Hitotsu-King)

An Atlantis/stone gate-themed Great-type Hitotsu-Ki evolved from Yamada, the director and Tsuyoshi's boss at Pheasant Consultant, to fulfil his desire to find a capable subordinate.

---

• Forced Transformation: Anyone struck by his ribbon is turned into pink orbs.
• Madness Mantra: "Work for me...!!"
• Mythology Gag: His weapons are one to the Goggle Five:
  • His clubs are an homage to Goggle Black's Black Clubs.
  • His hula hoop, an homage to Goggle Blue's Blue Ring.
  • His ball is an homage to Goggle Yellow's Yellow Ball.
  • His ribbon is an homage to Goggle Pink's Pink Ribbon.

Mahou-Ki

Portrayed by: Takashi Sakakibara

Skin: Purple Wizard (Hitotsu-Ki), Majin King (Hitotsu-King)

A wizard-themed Magic-type Hitotsu-Ki, and the second form evolved from ninja wannabe Minoru Ohno, to fulfil his desire to defeat Taro.

---

• The Bus Came Back: Ohno's emergence as Mahou-Ki makes the first time a single host became two Hitotsu-Ki on multiple occasions.
• Calling Your Attacks: He calls out the elemental magic he uses in his fights.
• Discard and Draw: Instead of his initial Shuriken/Ninja-themed power set, he uses a Wizard-themed power set on his second go-around as a Hitotsu-Ki.
• Elemental Powers: He's shown to cast lightning and earth magic.
• Instant Runes: He casts spells via runic circles like the Magirangers conjured in battle.
• Magic Wand: Wields one as Mahou-Ki.
• Mythology Gag: There's a very good reason he gets two monster forms based on Ninninjer and Magiranger - not only is AoNinja a wizard in training, he's trained by MagiYellow.
• The Only One Allowed to Defeat You: His sheer desire to defeat Taro is what transformed him into a Hitotsu-Ki the second time.
• Robe and Wizard Hat: He sports them over his ninja outfit and his Hitotsu-Ki form.

Kagaku-Ki

Portrayed by: Nanaha Itose

Skin: Dream Invention (Hitotsu-Ki), Explosive Grand Slam (Hitotsu-King)

A volcanic rock/chemical explosive-themed Science-type Hitotsu-Ki evolved from a woman named Mizuho Ijuin, to fulfil her desire to acquire "The Secret", a priceless portrait of her painted by her deceased boyfriend, Takeo Aota.

---

• The Bad Guy Wins: Zigzagged. She manages to steal the portrait she was chasing after with Inu Brother's help, though the Donbrothers still defeat her as Kagaku-King.
• Blackmail: She uses this to convince Tsubasa to help her steal "The Secret", by threatening to blab about his fugitive status to anyone who listens.
• Phantom Thief: Defied. Tsubasa stops Mizuho from being one by stating that sending a Calling Card only happens on TV and how using her real name on there is a very bad idea.
• Resist the Beast: As Kagaku-Ki, she can control her desire to the point of being able to cancel her transformation. This does not apply as Kagaku-King.

Bakuryuu-Ki

Portrayed by: Kouji Wakasugi

Skin: Abaremix (Hitotsu-Ki), Tyrannosaurus (Hitotsu-King)

A dinosaur-themed Blast Dragon-type Hitotsu-ki evolved from a company president named Nagai, to fulfil his desire for those around him to be faster.

---

• Bad Boss: From what we see of his host, the man constantly bullies his employees in a bid to get them to move faster.
• Dinosaurs Are Dragons: He is based on a dinosaur Sentai series and is shaped like a dragon.
• Giant Space Flea from Nowhere: He's yet another Hitotsu-ki that is tangential to the plot of the episode it appears in.
• Madness Mantra:
  "Too slow!!"
  "Can't you go faster?!"

Choushinsei-Ki

Portrayed by: Takashi Yano

Skin: Prism Star (Hitotsu-Ki), Prismatic Star (Hitotsu-King)

A prism-themed Supernova-type Hitotsu-ki evolved from Koyama, a young man addicted to spicy food, to fulfil his desire to indulge his cravings.

---

• Madness Mantra: "Not spicy enough...!!"

Tensou-Ki

Portrayed by: Yosuke Nishi (first host), Kenta Yamagishi (second host)

Skin: Angel Headder

An angel-themed Heavenly Armament-type Hitotsu-ki evolved from an unnamed Big Eater, to fulfil his desire to go on a diet. When his desire disappeared however, the power moves on to possess poor-selling street musician Ryuji Inui, who is also the temporary user of Inu Brother, to fulfill his desire for his ex-girlfriend Shoko to come back to him.

---

• Acrofatic: Its first host certainly qualifies, being a rotund Big Eater who's nonetheless agile enough to stymie the Donbrothers' efforts to defeat him.
• Earn Your Happy Ending: Both of its hosts go on to have success in their love lives, with the first meeting a Chubby Chaser who's attracted by his large appetite and Ryuji reconciling with Shoko.
• Foreshadowing: Mixed with Mythology Gag for Ryuji Inui. Despite not being Tensou-Ki initially, his busking billboard describes himself as having a "Skick Voice of Storms", a reference to Gosei Red's roll call^note "The Skick Power of Storms". Sure enough, he eventually becomes the second Tensou-Ki.
• Good Wings, Evil Wings: Has a pair of large white wings, befitting his angel motif.
• Land, Sea, Sky: Just like the Goseigers, it can fly and use earth and water attacks.
• Madness Mantra:
  • "Dieting...!!" (first host)
  • "Shoko--!!" (second host)

GoGo-Ki

Portrayed by: Takashi Sakakibara

Skin: Persistent Adventurer

A compass/explorer-themed Rumbling-type Hitotsu-ki, and the third form evolved from ninja/wizard wannabe Minoru Ohno, to fulfil his desire to defeat Taro.

---

• The Bus Came Back: The third time Ohno managed to become a Hitotsu-ki.
• Discard and Draw: This time, he's sporting an explorer-themed power set instead of a ninja or a wizard-themed power.
• Final Words: "Mom, I'm sorry—!"
• Heel–Face Revolving Door: His third appearance initially implies he has pulled a Heel–Face Turn, having put his ninja wannabe life behind him in favour of a proper career as a horse rancher and making his mother proud. However he begins to see ninja-related hallucinations from his horses, causing him to relapse back into his ninja ways and motive to defeat Taro.
• Mythology Gag: When he transforms into GoGo-Ki he uses their transformation call of "Start-up" before snapping his fingers and yelling "Attack" just like BoukenRed.
• Rule of Three: This is the third time he's become a Hitotsu-Ki.
• Uncertain Doom: Slain by the revived Sonoi this time, it is not shown if he was Killed Off for Real or placed into the Nōto prison as a result.

Taiyou-Ki

Portrayed by: Hirofumi Suzuki

Skin: Sunshine Employee

A sun-themed Solar-type Hitotsu-ki, and the second form evolved from Pheasant Consultant employee and Donbrother Tsuyoshi Kijino, to fulfil his desire to have his beloved wife Miho all to himself.

---

• Discard and Draw: This is Tsuyoshi's second go-around as a Hitotsu-ki, and this time has sun-themed powers rather than vehicle-based powers.
• Mythology Gag:
  • When he gets turned into Taiyou-Ki alongside Shinichi and Haruka, the three of them mimic Sun Vulcan's pose.
  • One of his attacks has him quote Sun Vulcan's opening theme: "Follow the sun, catch the sun".
• The Power of the Sun: He can create a miniature sun to attack with.
• Single-Issue Wonk: More obsessive about his wife (than normal), to the point that "Miho" is basically a Madness Mantra.

Tokusou-Ki

Portrayed by: Hiroo Ohtaka

Skin: Hell's Mascot Dog (Hitotsu-Ki), Big Police Dog (Hitotsu-King)

A police dog/siren-themed Special Investigations-type Hitotsu-ki evolved from an unnamed oden stand owner, to fulfil his desire to stop any and all criticism about his cooking.

---

• Animorphism: He becomes more dog-like upon becoming a Hitotsu-King, going on all fours and even attempting to pee on GolDon Onitaijin's leg.
• Can't Take Criticism: Any comments on his cooking that aren't 100% praise immediately set him off, triggering his transformation.
• Finger Firearms: Has machine guns built into his fingers as Tokusou-King.
• Hellhound: He's modeled on one, as a Mythology Gag to Doggie Kruger/Dekamaster and his moniker "Hell's Guard Dog".
• Maniac Tongue: Has two tongues hanging out of his mouth in both Hitotsu-Ki and -King forms.
• Punny Name: The "deka" in his skin name as a Hitotsu-King is a play on the Japanese slang for "detective", and dekai (デカい, "big").
• Small Name, Big Ego: Despite being the owner of a humble oden stand, he apparently thinks himself a genius chef. And he won't hear anything that implies otherwise.

Choujuu-Ki

Portrayed by: Ku Ijima

Skin: Life Academia (Hitotsu-ki), Life Dimension (Hitotsu-king)

A falcon/dolphin/lion-themed Super Beast-type Hitotsu-ki evolved from an unnamed physics student, to fulfil his desire to understand youth.

---

• Arm Cannon: His Hitotsu-King form has guns built into his palms and elbows.
• Giant Space Flea from Nowhere: Downplayed. Has pretty much no connection to the overarching plot involving the investigation into the Jūto, though he somehow pops up in Taro's delivery truck in an attempt to sate his desires.
• Mix-and-Match Critters: Is a chimeric Hitotsu-Ki based on multiple animals.
• Mythology Gag:
  • Pretty much every line of his dialogue is a reference to the theme songs of Liveman.
  • His host is a young man who spent his entire life studying and eventually has a mental breakdown in an amusement park as a result. The backstory is shared with Goh Omura/Dr. Obular, who also saw his past start to catch up with him in an amusement park.

Kyukyu-Ki

Portrayed by: Koji Kasai

Skin: Century's End Matoi (Hitotsu-ki), Century's End Liner (Hitotsu-king)

A firefighter-themed Rescue-type Hitotsu-ki evolved from a timid man named Kuga, to fulfil his desire to be rescued.

---

• Innocent Bystander: Subverted. While he's certainly thrust into perilous situations, his desire to be rescued from these ironically leads him to become a Hitotsu-Ki.
• One-Winged Angel: Twice. First he turns into Kyukyu-King, which resembles the Go-Liners in train formation, and after Toradora Onitaijin disconnects his train cars he turns into a form that resembles Beetle Mars.
• Playing with Fire: He can spew jets of fire that serve to make the battlefield a Battle Amongst the Flames.
• Weirdness Magnet: His desire stems from the fact that he keeps running into supernatural situations — becoming a hostage of "Tsubasa"'s raid of a restaurant, witnessing "Natsumi"'s superhuman powers, and lastly witnessing Don Momotaro and Sonoza confronting the Jūto leads him to believe he needs to be "saved" from the potential dangers of all these superpowered beings.

Seijuu-Ki

Portrayed by: Tomoki Hirose

Skin: Beast Armor's Light (Hitotsu-ki), Super Armor's Light (Hitotsu-king)

A chimera-themed Star Beast-type Hitotsu-Ki that initially manifested in ninja/wizard/explorer-wannabe Minoru Ohno before being transferred to and evolving from Nōto inspector Sonoshi, to fulfil the latter's desire for revenge on those who set them up to become a Hitotsu-Ki.

---

• Call-Back: Like Tensou-Ki, it's able to jump from one host to another, as Sonoza demonstrates by taking it from Minoru Ohno to Sonoshi.
• Loophole Abuse: Normally, Nōto cannot become Hitotsu-Ki on their own. However, nothing stops a Hitotsu-Ki from possessing a Nōto instead as long as it's near maturity, which makes The Plan work in the first place.
• Unwitting Pawn: The Hitotsu-Ki is made a pawn in the Donbrothers' and Nōto's plan to deal with Sonoshi.

Denshi-Ki

Portrayed by: Mika Tobari

Skin: DZ Mechanism Type-8022

A circuit board-themed Electronics-type Hitotsu-Ki evolved from a gourmet critic named Noriko Iida, to fulfil her desire to sample new and exotic dishes.

---

• Balloon Belly: She notably gains one from changing back to human after she consumes humans whenever she changes into a Hitotsu-Ki, but could not recall what made her stuffed.
• Earn Your Happy Ending: Noriko became a Hitotsu-Ki because she wanted to taste something new. She manages to do so at the end of the episode by tasting the food Tsubasa and Takamura made from the fruits inside her Pocket Dimension during her time as Denshi-Ki.
• Mythology Gag:
  • Denshi-Ki absorbs Tsubasa as one of her victims. Doesn't seem like a callback at first until you recall how the Denziman's mentor, a dog, sacrificed himself to essentially become an intergrated circuit in the Denziman's sole mech.
  • A meta one: the number 8022 which shows up on her face and skin name is a nod to the date the first episode of Denziman aired: February 2, 1980.

Ja-Ki

Portrayed by: Moeka Ukawa

Skin: Trump Cyborg (Hitotsu-ki), Big Bang Cyborg (Hitotsu-king)

A card suit-themed Evil-type Hitotsu-Ki evolved from a woman named Tamaki, to fulfil her desire for more attention.

---

• Mythology Gag:
  • Tamaki wears red boots that resemble those worn by Karen Mizuki/Heart Queen as a civilian.
  • Her desire for more attention nods to how JAKQ was cancelled due to low ratings.
• Odd Name Out: If the standard Hitotsu-Ki naming scheme was used, she'd be called Dengeki-Ki. The problem is that the more traditionally named Dengeki Sentai Changeman would also be named that, so they made a custom name for the more uniquely named J.A.K.Q. Dengekitai.
• Punny Name: Her hitotsu-ki name is derived from taking the "Ja" of JAKQ and giving it an equivalent kanji, in this case "邪/Evil", likely due to the One-Steve Limit of having a Dengeki-Ki later on.
• Unwitting Instigator of Doom: Her transformation into Ja-Ki leads to Don Killer finding where the Donbrothers are.

Mirai-Ki

Portrayed by: Hiroyuki Matsumoto

Skin: Chrono Driver α (Hitotsu-ki), Chrono Driver β (Hitotsu-King)

An owl/clock-themed Future-type Hitotsu-Ki evolved from a driving instructor named Muto, to fulfil his desire to have someone instruct him on how to deal with the Donbrothers' shenanigans.

---

• Catchphrase: "Okay!!", which becomes a Madness Mantra as a Hitotsu-Ki.
• Fish out of Water: Being an instructor for thirty years led him to believe he has Seen It All. However, his encounters with Haruka and the Donbrothers prove to him otherwise, putting him as such a loss his desire for someone to instruct him how to handle the situation turns him into a Hitotsu-Ki.
• Mythology Gag:
  • The school he works for, Oniga Mirai Driving School, has its logo modelled after the Timeranger show title.
  • His Hitotsu-ki form is heavily armored like Time Robo α, while his Hitotsu-King form is lightly armored like Time Robo β.
  • His Hitotsu-ki form is partially modeled on an owl, a reference to Tac.
• Time Master: He can loop back time as a Hitotsu-King, undoing the combinations of Toradragonjin and GolDon Onitaijin. It ends up being all for naught though, as the Donbrothers combine into Toradora Onitaijin Kiwami anyway.

Hikari-Ki

Portrayed by: Yukijiro Hotaru

Skin: Burning Aura

A Buddha-themed Light-type Hitotsu-Ki evolved from Santa Claus himself, to fulfil his desire to get back at the young people of the modern era, whom he sees as spoiled and greedy.

---

• Adaptational Jerkass: This version of Santa grew disillusioned with kids because he found that modern children have become unreceptive to the old traditional toys he gives as presents. And the one time he attempted to learn what modern kids did want landed him in jail (see Mistaken for Pedophile below), which causes him to completely lose faith in humanity in general for being apparent unsatisfiable customers.
• Adaptation Personality Change: This version of Santa is somehow able to run out of presents to give, which resulted in his encounter with Taro as a child when he asks the latter for his toys as donations. When Taro recounts this story to the others, Haruka and Shinichi believe "Santa" is instead a petty thief who robbed Taro's home.
• Bad Santa: The troubles Santa has faced, which also includes getting arrested by the police, would make him a host for Hikari-Ki.
• Irony: A Hitotsu-ki themed on a Hindu/Buddhist figure evolving from the embodiment of a Christian holiday.
• Mistaken for Pedophile: In one of his Christmas mishaps that led to his slump, a boy he was monitoring claimed he wanted a video game as his present. When he was about to present the game on Christmas day however, he overhears the boy telling his parents he wanted an older brother instead. This causes Santa to drop the video game and show up at the boy's front door dressed as a young boy, claiming to be his new older brother. He soon gets arrested by the police afterwards.
• Significant Wardrobe Shift: During his depression and time as Hikari-Ki, Santa does away with his beard and red outfit, appearing more like a homeless man. He returns to his iconic look after regaining his optimism from talking to Taro.

Himitsu-Ki

Portrayed by: Chikato Pride

Skin: Pentateuch Mask (Hitotsu-ki), Crunchy Dribbling (Hitotsu-king)

A darkness/rainbow-themed Secret-type Hitotsu-Ki evolved from a Phony Psychic named Tsutomu Kameda, to fulfil his desire to be saved from the Quirky Household Creepy Family he attempted to rob.

---

• Didn't Think This Through: Tsutomu finds out the hard way that Shinichi, a person that owns nothing worth of value and avoids greed, is a horrible target to swindle or rob from. And that's not accounting the Family of Choice he has with him who makes Tsutomu's decision that much more regretful.
• Me's a Crowd: As Himitsu-King, he can split into five copies in order to use his Rainbow Grenade attack.
• Mugging the Monster: Tsutomu tries to burgle the house of a person who happens to be one of the city's resident superheroes, and whose Family of Choice happens to be his superhero teammates. It ends up badly for him.
• Mythology Gag:
  • Like with Dai-Ki, he wields various weapons of the Gorengers in combat, including the Red Bute whip, Blue Cherry, Earring Bombs, and the Midomerang.
  • As Himitsu-King, he uses the Rainbow Grenade, whose method of use is identical to the Gorenger Hurricane.

Choudenshi-Ki

Portrayed by: Keigo Nakamura

Skin: BM Particle 8424 Type

An electronics/circuit board-themed Super Electron-type Hitotsu-Ki evolved from an office worker named Rikio Ono, to fulfil his desire for praise.

---

• Attention Whore: He becomes a Hitotsu-Ki due to his desire for praise from others.
• Giant Space Flea from Nowhere: He's largely detached from the overarching plot of his episode regarding the reveal of Tsubasa as Inu Brother among other plot lines.
• Gone Horribly Right: His desire for praise and attention from people leads him to cross paths with the Donbrothers, who promptly give him the attention he seeks by curb-stomping him.
• Mythology Gag: He and the company he works for have various Bioman references.
  • His appearance is based off Monster, while his boss and a female colleague have appearances based off Doctor Man and Farrah respectively.
  • His company is implied to delve in Bio-Particle technology, and his own proposal for a project has robot icons in the colors of the Biomen.
  • Like Denshi-Ki before him, his design has the serial number BM8424, referring to the show's debut date (February 4, 1984).
• One-Steve Limit: Downplayed. His last name Ono sounds phonetically like the infamous Minoru Ohno, however his is spelt with the kanji for "small" (小野) instead of Minoru's which uses the kanji for "big" (大野).

Hyakujuu-Ki

Portrayed by: Hirofumi Suzuki

Skin: Roaring Ferocious Beast

A cloud/animal-themed Hundred Beasts-type Hitotsu-Ki, and the third form evolved from Pheasant Consultant employee and Donbrother Tsuyoshi Kijino, to fulfil his desire for the missing Miho to return to his side.

---

• Mythology Gag:
  • His cloud motif is one to the Floating Continent of Animarium.
  • He can use the Animal Heart attack, just like GaoKing.
• Rule of Three: This is Tsuyoshi's third stint as a Hitotsu-Ki.

Dengeki-Ki

Portrayed by: Moeka Ukawa

Skin: Military Dragon (Hitotsu-ki), Ultra Thunderbolt (Hitotsu-king)

A soldier-themed Blitzkrieg-type Hitotsu-Ki, and the second form evolved from scorned paramour Tamaki, to fulfil her desire for more attention.

---

• Mythology Gag: The fact that the same person evolves into both the JAKQ Dengekitai and Dengeki Sentai Changeman Hitotsu-Ki is this. Under the normal Hitotsu-Ki naming scheme, both seasons' Hitotsu-Ki should be named Dengeki-Ki, with Ja-Ki being named as such to avoid that.

Sekai-Ki

Portrayed by: Ryota Togi

Skin: Battle Dancer (Hitotsu-ki), Battle Dancer J (Hitotsu-king)

A Japanese flag-themed World-type Hitotsu-Ki evolved from Tamaki's boyfriend Shinnosuke, to fulfil his desire for her to return to normal.

---

• Mythology Gag:
  • He's the boyfriend of the former Ja-Ki, a nod to how Ja-Ki and Sekai-Ki are the only Hitotsu-Ki to break the normal Hitotsu-Ki naming scheme.
  • His outfit includes two copies of the letter J on the front shoulder regions.
• Odd Name Out: One of two Hitotsu-Ki to break the standard naming scheme, as Battle Fever J is the only season that cannot follow it.

Ohsama-Ki

Portrayed by: Takashi Sakakibara

Skin: King's Crown

A regalia/insect-themed Monarch-type Hitotsu-ki, and the fourth form evolved from ninja/wizard/explorer wannabe Minoru Ohno, based on a forced desire to defeat his rival Taro Momoi.

---

• Early-Bird Cameo: In a sense. His Hitotsu-Ki form is based on the succeeding Sentai rather than one of Donbrothers' many predecessors.
• Me's a Crowd: Can create up to four clones of himself.
• Mythology Gag: An inversion, being an allusion to a succeeding Sentai rather than a preceding one; he, along with his clones, correspond to the main five King-Ohgers' colors.
• Punny Name: The "Oh" in Minoru's surname (written as 大) is homonymous to the Japanese word for king (王).
• Puppet King: Defied. While the Overseers had created him in an attempt to beat the Donbrothers, he chooses to defy their orders and go off to do his own thing, forcing the former to ask for the Donbrothers' help.
• Requisite Royal Regalia: His main motif, complete with his armor being shaped like a crown and him wielding a scepter.
• Turned Against Their Masters: For the most part, Hitotsu-Ki are born on their own from the desires of humanity. Ohsama-Ki is one of the few forced transformations with the Overseers intending on him to destroy the Donbrothers. However, he defies them and goes to do his own thing.

Others

"Mother"

Voiced by: Mamiko Noto

Fight, Murasame!

A mysterious entity who awakens and controls Don Murasame for her own ends.

---

• Ambiguous Situation: She appears to have an unknown degree of synchronization with Don Murasame, as she also expresses pain whenever the latter is injured.
• Evil Matriarch: Don Murasame's "Mother" is no friend to the heroes, sending Murasame to attack them repeatedly. She's also goads Murasame into embracing violent instincts, which tends to result in him rampaging as Onitajin Murasame.
• Evil Versus Evil: Mother's control of Murasame already pits her against against the Nōto by circumstance, which results in brief clashes between Murasame and the generals after his initial awakening. Mother also encourages him to target the Juto, being a Living Weapon designed specifically to kill them.
• Mission Control: Advises Don Murasame as The Voice in his head.
• Morality Chain: Exploited. The Murasame of Naoki Shiina's timeline lacks a "Mother," which gives him pause when he's able to hear her from his double's mind. The original uses the distraction she causes to deliver a final blow.
• Oh, Crap!: She's absolutely aghast when Murasame pledges allegiance to Tsubasa at the end of #40 for saving him from the Sayama Juto, reinforcing that they're supposed to be enemies. She's ignored.
• Reasonable Authority Figure: After Murasame bonds with the twin Jiros' over what it means "to live," Mother realizes she was being too dismissive of Murasame's concerns and agrees to listen to him more going forward.
• Spanner in the Works: Her awakening Murasame defies the Nōto and their Council, who sought to keep their Living Weapon contained.
• Split Personality: Murasame's conversation with Jiro in #29 implies that she is one to him, much like how Dangerous Jiro is one to Jiro.

Ninjarksword/Don Murasame

Portrayed by: Ayumu Murase (voice), Takahiro Yoneoka (suit)

The jaws that have snapped awake! Don Murasame!

Don Murasame! Kiri-Sute Sorry!^note Sorry for the Strikedown!

Yes, Mother.

A mysterious purple warrior who was kept in stasis in the Nōto base until "Mother" awakened him to serve her. His true form is the Ninjarksword, a shark-themed living ninja sword that becomes his weapon in Avatar Warrior form.

---

• 11th-Hour Ranger: He joins the Donbrothers in the final episode after spending a majority of the endgame as Tsubasa's weapon, even getting his own roll-call.
• Character Development: Discussed. Sonoza reveals in #48 that he sealed the Ninjarksword's power using pages from Haruka's ''First Love Hero" in the hopes that the ninja would read and learn from them. This would end up causing him to join the Donbrothers in the final episode.
• Contrasting Sequel Antagonist: Both Stacy/Stacaesar and Murasame are evil counterparts to the main heroes, with their Ranger forms and weapons being purple ripoffs from the hero's form and gear. They also overwhelm the heroes on their debut. However, Stacy was already up and about from the beginning of his show while Don Murasame was in stasis from the first episode of his series. Stacy is a separate being who uses a gun while Don Murasame is a sword who can also wield it in his Ranger form. Stacy is also defined by his rivalries with Kaito and Zocks whereas Murasame has no (known) connections to Taro and his relationship with the twin Jiros is primarily positive despite their affiliations.
• Desperately Looking for a Purpose in Life: He starts to show shades of this in #21 when he questions the purpose of his existence, so much so that even Dangerous Jiro was able to feel sorrow emanating from him. However "Mother" just tells him to ignore these thoughts and do what she wants of him. In #29, the question bugs him so much that he actively disregards Mother's orders and fraternizes with the two Jiros to find an answer to it.
• Demoted to Extra: He gets only one scene in the Donbrothers vs. Zenkaiger movie, where it's revealed that he now works at Café Donbura.
• The Dreaded: Both the Nōto and their Council are fearful of Don Murasame's arrival, given he wasn't meant to be awakened yet.
• Evil Knockoff: He's a purple, evil-looking doppelganger of Don Momotaro. Subverted in the final episode.
• Evil Versus Evil: Don Murasame clashes with the Nōto as well as the Donbrothers. His Mother also shows interest in protecting the Anoni from the Juto too. Until in the final episode where he joins the Donbrothers.
• Evil Weapon: Anyone other than Murasame (and seemingly Taro) that grips the Ninjark sword is reduced to a feral Blood Knight until disarmed.
• Expy: A swordsman fused to his own blade whose "body" can change its mass to phase through walls and floors? Sounds a lot like Kamen Rider Saikou. His blade's ability to possess unauthorized wielders also brings Gaisoulg's evil armor to mind.
• Gratuitous English: The "Kiri-Sute Sorry!" of his transformation is a half-translation of Kiri-Sute Gomen ("sanction to cut down and walk away"), a right afforded to samurai when insulted by those of lower class.
• Heel–Face Turn: He joins the Donbrothers in the final episode and rebels against the council.
• Highly-Visible Ninja: The wielder of the Ninjark Sword is a very bright, grape-flavored hue.
• I Owe You My Life: He pledges himself to Tsubasa at the end of #40 in gratitude for saving him from nearly being taken by the Juto while ignoring Mother's orders.
• Informed Flaw: The opening to #39 mentions Murasame having bouts of madness, yet the only insanity ever shown is from other people that grip the Ninjark Sword. The following episode is the only time Murasame shows any form of battle tendency, and it's depicted as a power-high rather than anything mental.
• Instrumental Weapon: Because of his Reverse Grip way of wielding the Ninjarksword, when he spins its central gear with his other hand to activate his abilities the motion is akin to strumming a guitar.
• Living Weapon: Twofold. His "body" is merely a construct that extends from the Ninjark Sword. He's also an artificial weapon created by the Council that had been kept in stasis until Mother awakened him for unknown purposes.
• Meaningful Name:
  • "Murasame" is the name of a sword with water-related powers from Nansō Satomi Hakkenden. Each of the novel's eight protagonists was born from their mother's magic prayer beads as an embodiment of a different Confucian virtue, with Murasame's wielder Shino embodying "duty to one's parents".
  • Murasame is also a portmanteau of Murasaki ("Purple") and Same ("Shark").
  • "Ninjark" is a portmanteau of "ninja" and "shark".
• Odd Friendship: Is beginning to develop one with the two Jiros, who bond with him in #29 over their shared seeking of purpose.
• Out of Focus: His presence is greatly reduced in the series' later half, even in the episodes where one would think he'd play a major role — namely, the Forest of Slumbers subplot. He eventually comes back in the final episode.
• Palette Swap: The Ninjarksword is basically Don Momotaro's Zanglassword colored purple and with a different blade.
• Purple Is Powerful: In line with Evil Rangers of recent seasons past, Murasame is purple-hued, made its debut making short work of all the Donbrothers, and not one of the good guys until the final episode.
• Put on a Bus: Once he pleges his allegience to Tsubasa, he disappears for the endgame, serving only as a new weapon for them to use.
• The Quiet One: He tends to not speak outside of his responses to Mother, grunts, and announcing attacks.
• Reverse Grip: He wields the Ninjarksword this way.
• Serrated Blade of Pain: As the Ninjarksword, his blade has a jagged edge in contrast to the Zanglassword's smooth edge.
• Shock and Awe: Don Murasame can recharge himself through the city's power lines, causing sporadic blackouts.
• Sympathetic Sentient Weapon: Murasame is a weapon created by the Nōto to counter the Juto. He's also mentally a child and isn't actively malicious; Desperately Looking for a Purpose in Life and only opposing the heroes by circumstance. The generals treat him like they would a tool and Mother isn't the most understanding about his concerns... though she has realized this.
• Threatening Shark: He's themed on a shark, and is an antagonist to the Donbrothers. At least, until the final episode.
• Transforming Mecha: Like Don Doragoku Alter, he's capable of transforming between a humanoid form and a shark-like animal mode in his Alter Mode.
• Turned Against Their Masters: Downplayed. Don Murasame is a Living Weapon created by the Nōto Council. While Mother has seized control of him for her own dubious ends, Murasame generally finds himself working with the Nōto regardless. It's played straight in the final episode, where he turns on Sonoya and joins the heroes.
• Tyke Bomb: A Living Weapon created by the Nōto Council in a bid to defeat the Jūto, who acts like a child.
• Villain-Beating Artifact: Being a Living Weapon, the Ninjark Sword is revealed to be one of the few things that can destroy a Juto.
• Villain Takes an Interest: Much like how the Nōto generals take notice of specific Donbrothers, Murasame finds the twin Jiros' Split Personality arrangement curious and opens a dialog with them against Mother's wishes.
• Vocal Dissonance: His voice is high-pitched and flat, greatly contrasting with his menacing appearance. Justified, since he was activated earlier than the Nōto Council had planned and is for all intents and purposes a child.
• Wrong Context Magic: He is able to change into his Alter Mode, Avatar Change into past warriors, and become Black Onitaijin Murasame, all without the use of Avataro Gears. Specifically for the 2nd ability, he transforms into those under the category of "Rival Warriors"^note The Psycho Rangers and warriors who notably stood against the main team as The Rival for extended periods, such as Abare Killer and Stacaesar., and also has access to Sentai teams whose Avataro Gears have not yet been retrieved by the Donbrothers themselves. And unlike the Donbrothers who, even with better skill, can't harm Juto, Murasame can kill them just fine.

Don Killer and Don Killer Killer

Don Killer portrayed by: Kouhei Higuchi
Don Killer Killer portrayed by: Yuuki Beppu

Don Killer is the ultimate culmination of the Don Clan's technology — an invincible android made as a failsafe to eliminate the Donbrothers should they deviate from their mission and go out of control.

Don Killer Killer, however, is another similarly-constructed android, this time as a failsafe for Don Killer himself should he be deployed by accident or go out of control.

---

• The Dreaded: Don Killer is undeniably the most terrifying threat in the entire series, thanks to it's sheer strength and ruthlessness.
• Eating Machine: Don Killer is shown to be able to consume food like parfaits.
• Establishing Character Moment: Don Killer blocks Taro's sword with his fingers.
• Failsafe Failure: The Don Clan created the Don Killer series of robots to cull a team of rogue Donbrothers, as well as a secondary to cull a rogue Killer. However, no emergency shutdown was ever devised for either of the robots - Both were only activated by Contrived Coincidence. If Jiro hadn't stumbled onto Killer Killer's remote or if the two robots' differing objectives hadn't forced conflict, everyone present would've died.
• Fearful Symmetry: Their attacks are so evenly matched that the two leaving Earth to continue their Forever War is arguably the best outcome for everyone involved.
• Godzilla Threshold: Don Killer is such a threat to the Donbrothers that even Sonoi attempted to lead the Nōto generals in eliminating him, despite the potential trouble with the Council it would cause for them. However, a coincidental mustard contamination causes Don Killer to fail to recognise them as allies from Ideon, resulting in him easily curb-stomping them out of pure self-defence as they instantly declare a retreat.
• Gone Horribly Right: Don Killer was created by the Don Clan as a failsafe in case the Donbrothers deviate from their mission. Unfortunately, Don Killer is activated on accident but tries to carry out its mission regardless. It proves to be too powerful for the team to handle and almost destroys them, only being stopped by being locked into a Forever War with Don Killer Killer. They did seem aware of this being a possibility, so they made Don Killer Killer to act as a failsafe.
• Identical Stranger: Don Killer resembles Taro, while Don Killer Killer resembles Shinichi. While it's understandable that Don Killer would look like Don Momotaro, there's far less of a reason why Don Killer Killer would resemble an otherwise normal human who just so happened to become a Donbrother.
• Implacable Man: Or Implacable Android, in this case. The Donbrothers' attacks do nothing against Don Killer.
• Knight of Cerebus: Don Killer's activation is an event so shocking that Taro tells his team to make peace with their incoming doom.
• Near-Villain Victory: The Don Killer is entirely adaptive, incommunicable and above all invincible. Even Taro is scared of the thing and by the end of its own episode, has the primary team cornered with no out in sight. Jiro randomly stumbling onto the Killer Killer's activation device in Terasaki's house is the only thing that prevents the show from ending right there.
• Non-Indicative Name: Despite Don Killer's name and the fact it has more than enough power to kill the Donbrothers, it oddly enough didn't kill Tsubasa, Shinichi nor Tsuyoshi when it cornered them and instead crippled them through Metronomic Man Mashing.
• Outside-Context Problem: Don Killer's abilities are more along the likes of something you'd see from a Hollywood film than a Tokusatsu show and the Donbrothers are basically helpless against it as a result. It even causes legitimately serious injuries like broken bones as opposed to what a typical Monster of the Week can dish out.
• Sealed Evil in a Can: Don Killer was sealed away, with its activation button guarded by Kaito. When the Donbrothers inadvertently activate it, it results in tragedy for everyone involved.
• Sealed Evil in a Duel: In the end neither the Donbrothers nor the Nōto were capable of shutting Don Killer down with the only thing capable of matching it being Don Killer Killer, who continues to fight against Don Killer in space most likely for eternity.
• Terminator Impersonator: Don Killer is basically a Terminator programmed to kill the Donbrothers if they go rogue. Don Killer Killer is a second one programmed to kill Don Killer if it went rogue.
• Weaksauce Weakness: Subverted. Kaito attempts to neutralize Don Killer by tampering with its parfait with mustard, but all it does is make it attack the Nōto instead, and it ends up being a temporary inconvenience as the mustard is flushed out of Don Killer's system anyway.

The Don Clan

A race of Human Aliens who once co-existed with the Nōto in Ideon, and the originators of the Donbrothers' powers. They were wiped to extinction by the Nōto twenty-one years ago due to performing dangerous experiments in an attempt to seek peaceful co-existence with humans, in particular for the act of creating the Jūto.

---

• The Atoner: Attempted. Terasaki's final moments reveal that the Don Clan were scrambling to appoint guardians to keep the Juto at-bay. The Noto's bloodlust ruined that before it could start.
• Big Good: The Don Clan wanted to peacefully co-exist with humanity instead of keep away from it; even going as far as to create the Juto in an attempt to stop mooching off of Humanity's collective desire. They instead ended up creating ravenous body-duplicating monsters, which is all the excuse the Noto needed to destroy them.
• Civil War: The casualties of one. The Noto massacred the Don Clan due to a mixture of ideological differences and the inherent threat posed by the newly-created Juto creatures.
• Crazy-Prepared: They created the Donbrothers' arsenal to help Taro, which is coded to disarm and find a new user if it's used for selfish reasons. If the whole team somehow goes rogue, the Don Killer could be activated to deal with them. And the Don Killer Killer could be activated to deal with it.
• Create Your Own Villain: The Don Clan attempted to create Artificial Humans to replace their desire-based food source. They made monsters instead.
• Exceptionally Tolerant: What separated the Don Clan from the Noto was their intent to co-exist with humanity. The Juto project was designed to counteract Ideon's reliance on human desire using knockoffs as substitutes. They made unstable monsters instead, inspiring the Noto to act on already-brewing tensions and depose the Clan outright.
• The Ghost: Aside from a dwindling number of sole survivors that are revealed over the course of the story, the original Don Clan were never shown onscreen.
• Nice Job Breaking It, Hero: The Don Clan's attempts to create Artificial Humans to leech desire from horribly backfired; creating a species of hostile appearance-snatching cryptids. They attempted to seal the creatures away in penance, but the Noto weren't satisfied and (seemingly) massacred them to the man...practically ensuring that the Juto would be a threat in the future.
• Reed Richards Is Useless: They were allegedly smart enough to create an infinite energy source, but said technology was solely used on a failsafe Killer Robot against the Donbrothers, and a secondary one for the first; resulting in two immortal paperweights that are infinitely stuck fighting each other.
• Ruling Family Massacre: They were the previous rulers of Ideon until the Noto rebelled and slaughtered them all.

Mecha

Black Onitaijin Murasame

Portrayed by: Takahiro Yoneoka (motion capture)

The personal robot of Don Murasame.

---

• BFS: Don Onitaijin's Kiji Swords are replaced by the serrated Sawshark swords, which Murasame can control telepathically.
• Evil Knockoff: Of Don Onitaijin, complete with silent and non-expressive Robotaro knockoffs as its various parts.
• Red Eyes, Take Warning: Onitaijin Murasame and its knockoff Robotaro components have sharp red visors in contrast to the heroes' black.
