This is a partial character sheet for Ohsama Sentai King-Ohger. Subjective trope and audience reactions should go on the YMMV page.

Emblem of the Bognaarok Empire

"Pestes rex eris!"

— The Empire's motto, spoken by all of its members.

A vast subterranean empire comprised of humanoid arthropods, who were defeated 2,000 years ago by King-Ohger and its chosen warriors after attempting to conquer Tikyū. They return in the present day with the goal of rewriting the balance between humanity and empire by taking the three Greater Shugods to grant their wish.

After Dethnaarok's death and Jeramie's ascension to the throne, the empire is officially recognized as Tikyu's sixth nation and renamed the "Kingdom of the In-between".

General Tropes

• Alien Blood: Their blood is black in color.
• Always Chaotic Evil: Subverted. Most of the Bognaarok are aggressive to the kingdoms of Tikyu for social reasons rather than some inherent hatred. It was the deliberate manipulation of Kamejim that prevented any chance of peace with Jeremie unknowingly dividing the races further with his prophecy.
• Ancient Evil: They've been around for at least 2,000 years.
• Arc Villain: They are the antagonists from #1 to #26.
• Atrocious Arthropods: They are an evil race of insectoid creatures.
• Beneath the Earth: As their name suggestions, they live underneath the earth in a tunnel network.
• Brought to You by the Letter "S": Exaggerated. The Bognaarok's emblem is the empire's name spelt out in full stylized English, which their leaders have emblazoned on their bodies.
• Canis Latinicus: The empire's motto: "Pestes rex eris!", which roughly translates out to "You will be the king of pests!"
• Contrasting Sequel Antagonist: The Nōto were a group of vigilantes that were moreso "antagonists" than "villains" in the traditional sense (they opposed the Monster of the Week in the same vein the Donbrothers did and were only malicious in the sense of how unfettered they were compared to the heroes, having no greater plan or motive than stabilizing their realm), were led by a reclusive Council over-reliant on its generals as proxies, having only ever acted on its own once, and its generals were Punch Clock Villains with various redeeming traits that fraternized with (and eventually joined) the enemy. Inversely, the Bognaarok are Obviously Evil and do not hide it — being clearly hostile to humanity and seeking the Greater Shugods for an Evil Plan. The Empire's higher-ups are not only the source of the show's monsters but frequently confront the heroes alongside their troops - possessing a veritable army led with a We Have Reserves mentality.
• Designated Villain: Invoked: the Galactinsects deliberately orchestrated the Bognaarok to be seen as villains to cause the forever war between them and humans for their sadistic games.
• Easily Forgiven: Downplayed. While Gira says that the Bognaarok's attacks on humanity are unforgivable, he does understand where they are coming from and sincerely apologizes for not seeing things from their perspective.
• Elaborate Underground Base: It's occasionally this for the monarchs post-Time Skip.
• The Empire: They're an expansionist horde of humanoid arthropods seeking to conquer Tikyū and exterminate the human race.
• Explosive Breeder: Dethnaarok's boast to Gira in #9 implies as much, feeding into their We Have Reserves mentality.
• Fantastic Racism: They are actually the victims of this. It was revealed that there wasn't any official historical document stating that they are the enemies of Tikyū and/or humanity to begin with. The truth is that the Galactinsects forced Tikyū's human rulers to attack the Bognaarok and they were treated as murderous monsters for two millennia, with the Legend of King-Ohger written by Jeramie further painting them as such.
• Grim Up North: Heroic variant: Upon Jeramie taking the throne, he moves Bognaarok's capital to below Gokkan.
• Heel–Race Turn: They end all hostilities with the Five Kingdoms — and by extension, mankind — upon Jeramie taking the throne.
• Meaningful Name: "Bognaarok" is based on a portmanteau of "Bug", "Ragnarök" and "Naraku".
• The Morlocks: A subterranean throng of beastly ^note albeit bug-like rather than ape-like humanoids driven by oppression to wage war on the surface.
• My Nayme Is: Pronounced "Bug-narok", but spelt as "Bognaarok", according to their emblem. The romanization officializes it as "Bug Naraku."
• Not Afraid to Die: Dethnaarok boasts to Gira that his species is flawless because they do not fear death. Thus, they have no qualms about sending thousands of Sanagim to die in battle. Much of Jeramie's rule has been dedicated to trying to convert these attitudes into helping people instead, while also reminding them the value of their lives.
• Out of Focus: Downplayed, post-Time Skip. Bug Naraku is sired as an official sixth nation, until Jeramie is quickly forced to enact a haphazard Zero-Approval Gambit to save the other monarchs from political headaches and the majority of its "citizens" are eventually killed and reanimated by Grodie as Mooks later on; effectively reducing the kingdom's role to "occasional monarch meeting room" during the show's latter half. It's not until #47 that Bug Naraku has a chance to really contribute: serving as a shelter for refugees during the second Fury of the Gods.
• Powered by a Forsaken Child: #22 reveals what the Kaijim use to turn into giants: Shugod Souls. While it was assumed that ingesting Shuggod Souls kills the consumer, it was later revealed to induce Loss of Identity and potentially Death of Personality.
• The Prophecy: #10 reveals the Empire as operating under the machinations of one, in which they're fated to crush all other forms of life. It was a centuries-long grift by Jeramie to ensure they stole the Greater Shugod souls for him.
• Retcon: Early into the show, Hymeno's research established the Bug Naraku as a parallel evolution of humanity caused by the species' consumption of Shugod Souls. #47 reveals that the Bug Naraku were instead former alien victims of the Galactinsects that migrated to Tikyu the exact same way Earthlings did.
• Sigil Spam: Like the five kingdoms, all its members have the empire's insignia on their persons.
• Sixth Ranger: They join the Quintet Alliance after Jeramie takes over and requests their accession to his fellow monarchs, which they accept.
• Standard Evil Empire Hierarchy:
  • The Emperor: Dethnaarok, as the empire's ruler.
  • The Right Hand/The Oddball: Kamejim, as imperial prime minister and chief researcher.
  • The General: Daigorg, as Dethnaarok's chief enforcer.
• Unwitting Pawn: #10 reveals that The Empire's pursuit of the Greater Shugods was on behalf of a prophecy, which they had following to the letter. Said story was a fabrication by Jeramie, who strung them along to this exact point to steal the three souls from under their noses.
• Was Once a Man: #26 shows that Bognaarok DNA is remarkably similar to human DNA (which also explains why Jeramie was able to exist in the first place), but years of being forced underground combined with consumption of Shugod Souls has caused them to take on a monstrous, insectoid appearance.
• We Have Reserves: Their idea of a Rousing Speech involves declaring to their soldiers that they're completely disposable. It doesn't matter how many Sanagim die — as long as they kill a greater number of humans in the process, even if it's just one more, the Bognaarok Empire will call it a victory. Horrifyingly, this works.
• Worth It: The official stance of the Bognaarok is exterminating humanity and winning the war is worth any price. If they launch an attack it doesn't matter how many of their own die, they consider any human death toll being more than their death toll by just one as a win for them.

Royal Family

Abyss King Dethnaarok VIII

Portrayed by: Tomoyuki Shimura (voice), Riichi Seike (suit)

Habitat: Shugoddam (morning, noon)
Favorite: Tikyu
King: Abyss King

The supreme ruler of the Bognaarok Empire. His goal is to rewrite the balance of power between humans and the Empire.

---

• Alas, Poor Villain: He was pushed by Jeramie's prophecies to become a genocidal maniac and was killed just as he was about to give humans a chance.
• Anatomy Arsenal: Can extend worm-shaped tentacles from his person to attack his enemies, which can be further enlarged to titanic size to destroy buildings. He can also create weapons from his body material.
• Back from the Dead: Returns from Hākabāka to provide aid in the final battle with Dagded before dragging Kanejim off to the underworld to personally oversee his punishment.
• Big Bad Ensemble: With King Racules. While they're both on opposing sides, Dethnaarok's main goal is to replace humankind with the Bognaarok as the dominant species.
• Big Damn Heroes: In episode 48.
• Casting Gag: This isn't the first time that Tomoyuki Shimura voiced an non-human character with a Then Let Me Be Evil mentality after he and others like him suffer prejudice by others for being villians in a story, being talked down by the main protagonist with a more dangerous antagonist taking over for the duration of the series.
• Char Clone: Dethnaarok embodies the Char's Counterattack archetype of this trope; a leader of his antagonist faction who embraces the notion of a villain out of misguided and tragic notions that even forced him to wipe out an entire planet in mutually assured destruction. His final moments is spent with acknowledging the horrors of his ways and making peace with the protagonist, the same way as Char acknowledging mankind's potential once the Axis Shock is averted.
• Death Seeker: Implied repeatedly in his ideals if it means his death would take a large amount of humans down with him. But following the reveal of his motives, he believes that wiping out all life on Tikyū is the only way true peace could be achieved.
• Disc-One Final Boss: He's the main antagonist of the first half of the series. He gets killed by Kamejim once his role as an antagonist ends.
• Didn't See That Coming: Had a very clever plan to disable Legend King-Ohger at the right time so the monarchs are unable to prevent him from sealing the three Greater Shugods. The only reason it didn't work was due to Jeramie stealing their Shugod Souls for his own ends. Justified as Jeramie fabricated the legend along with being the last person Dethnaarok would have ever expected to betray him.
• The Dreaded: A name like "Abyss King Deathnarok" has that effect.
• The Emperor: Of the quintessential Evil Overlord, bloodthirsty conqueror variety.
• Et Tu, Brute?: Does NOT take the revelation that Jeramie has been using him and his forces all along for his own goals well AT ALL.
• Evil Sounds Deep: Tomoyuki Shimura uses a subterranean-level, guttural voice for him.
• Even Evil Has Loved Ones: #26 reveals that he has a companion in the form of a mini-Shugod, Tarantula Abyss; notably, it's the only being whom he will never harm, nor let any harm come to.
• Expy: Of Ransik, a ruthless nonhuman dragged into a Cycle of Revenge between his kind and humans with the ability to produce weapons from his body. Both have a Treacherous Advisor who act on their own hidden agenda.
• Face Death with Dignity: Fatally stabbed with a focused beam of light about to vaporize him, Deathnarok accepts his demise as Jeramie tried to free him and get him to safety.
• Freudian Excuse: He actually has a good reason why he despises humans so much because of a legend made by Jeramie 2,000 years ago that causes Bognaarok to be discriminated therefore he sees no reason to coexist with humans and tries any means to wipe them all out.
• Frontline General: One of the few Sentai main villains who is willing to lead troops into battle or fight the rangers himself. Episode 9 has him confront each of the Ohsama Sentai personally and wipe the floor with them as part of his greater plan to unleash his cocoons upon the kingdoms.
• Good Cop/Bad Cop: While his advisor Kamejim is willing to feign negotiation, Dethnaarok doesn't bother and will usually just settle for a show of force.
• Heel–Face Door-Slam: Initially he seems to be on the verge of atoning for his misdeeds, but Kamejim then proceeds to betray him.
• Humiliation Conga: He gets one starting in episode 11 when Jeramie immobilizes him after sabotaging his plans and then shooting him at point-blank range. Then the next episode sees Jeramie poisoning him as Spider Kumonos during their fight, forced to fall back as the poison becomes unbearable while watching Spider Kumonos walk away at his leisure.
• King Bob the Nth: He's the eighth of his name.
• A Lighter Shade of Black: While he is a ruthless ruler willing to exterminate humanity, his motive ultimately stems from the Bognaarok being pitted against humanity and becoming the villains of Jeramie's story in the process, in contrast with Racules willing to gain power at any cost and Dagded seeking amusement by igniting wars all over the universe.
• Madden Into Misanthropy: Jeramie's prophecy caused the humans to depise his kind, eventually resenting them.
• Meaningful Name: His name is a portmanteau of "death", "Ragnarök", and "Naraku".
• My Nayme Is: His name is pronounced "Desnarok", with the highlighted part spelled the same as that of the empire he rules.
• Names to Run Away from Really Fast: Pretty sure that someone with the title of "Abyss^note In the sense of "hell" King" isn't one of the good guys here, much less someone with "death" in their name.
• No-Nonsense Nemesis: Dethnaarok doesn't waste words or time on complicated schemes. He's blunt and straightforward when when making his demands, will tear down entire city blocks as a show of force and will go out of his way to confront his foes as part of his plans. He also shows little patience for Kamejim and his schemes and throttles him when one of them goes awry.
• Ominous Opera Cape: Dons a long, voluminous black cape, complete with High Collar of Doom.
• Omnicidal Maniac: Justified. Due to Jeramie's prophecies depicting the Bognaarok as evil, Dethnaarok became an Absolute Xenophobe seeking to slaughter humankind and conditioned his forces to sacrifice themselves if means killing as many humans as they can. He ultimately follows his own dogma when he infects Tikyū's core to commit an act of mutually assured destruction.
  "Kill all the humans. Kill them, even if it kills you."
• Rank Scales with Asskicking: Is the emperor of the Bognaarok Empire and has demonstrated the capability of wrecking multiple buildings at once. #9 of the series showcases the four ruling rangers try to take him on individually, each battle ending them in beaten to the point of unconsciousness. Gira himself gets quickly disarmed and captured without too much effort on Dethnaarok's part.
• Rasputinian Death: It takes a lot to finally bring him down. His defeat at the hands of God King-Ohger only shrinks him down back to normal size, and even in a weakened state he manages to go toe to toe with the heroes. Then during his duel with Jeramie he gets impaled by Kamejim's staff, which still doesn't kill him, but leaves him open to getting vaporized by a beam of light, presumably fired by an outside force.
• Red and Black and Evil All Over: He's the main villain, and is clad in crimson and black armor.
• Repetitive Name: His name and title in Japanese is Naraku-ō Dezunaraku.
• Royals Who Actually Do Something: Unlike previous Sentai main villains, he's shown to be more willing to confront the heroes personally to get the job done.
• Serrated Blade of Pain: His BFS Naraklaymore has a jagged edge, and he's the main villain of the first arc.
• Take Up My Sword: In an odd anti-villain to hero version, a dying Dethnaarok passes on the Bognaarok's throne to Jeramie while entrusting their people will thrive under his heir's rule.
• Then Let Me Be Evil: #24 reveals that his hatred of humans stems from the discrimination his species faced as a result of Jeramie portraying the Bognaarok as the villains of the legend of King-Ohger. This resulted in him Becoming the Mask and, believing it to be the only way to make things equal, is scheming to outright wipe out the planet.
• Tragic Villain: Ruling the Bognaarok, the racism his kind suffered at the hands of humans forces him to embrace their views and become a monsterous tyrant willing to kill everyone and himself to achieve his ideal peace.
• Villain Ball: Surprisingly subverted. At first, it seemed like it was played straight when he let Gira go in order to have him fall into despair when he sees the fall of humanity first hand, allowing him and the others to summon and form Legend King-Ohger. However, the very next episode reveals that them doing so was exactly what he wanted so that Nagabajim is able to secretly plant bombs to disable that form at the right time to so he can execute the true plan.

Nephila Idmonaarok Ne

Portrayed by: Kikuko Inoue (voice); Yuichi Hachisuka [episode 12], Yuki Miyazawa [episodes 30-31, 49] (suit)

The unsevered thread! Nephila Idmonaarok Ne!

Habitat: Ishabana (daytime), Shugoddam (daytime)
Favorite: Jeramie Brasieri
King: Mother King

Jeramie's mother, who was exiled from the Bognaarok for falling in love with a human.

---

• Action Mom: Jeramie's mother is one of the most powerful Bognaarok in the series, strong enough to not only take on but actually kill Daigorg himself one-on-one.
• Combat Stilettos: Her design incorporates high heels, which she uses to devastating effect.
• Deceased Parents Are the Best: From what little we see from her, Nephila was an incredibly kind, yet strong soul dedicated to protecting Jeramie at all costs, even on her deathbed.
• Fallen Princess: #24 has Jeramie reveal that he's related to Dethnaarok himself through her, making her of Bognaarok royalty.
• Genghis Gambit: Subverted. She attempted to end the Bognaarok civil war by defeating Daigorg in combat, but only ended up having the other Bognaarok gang up on her instead, leading to her demise.
• Gun Fu: Primarily relies on punches and kicks, with her using the Venomix Shooter as a sidearm 2,000 years ago.
• Interspecies Romance: With the sixth hero of the first Ohsama Sentai.
• Lightning Bruiser: Her fighting style relies on her delivering fast, powerful attacks from both close and long range.
• Mama Bear: She's willing to face the Deathblow General himself, if it means protecting her son. When she's revived, all her actions are driven by her need to save Jeramie and be saved by him.
  • Just as a resurrected Grodie tries to attack Jeramie, she steps in and delivers a No-Holds-Barred Beatdown, leaving Jeramie in Stunned Silence.
• Meaningful Name: Her name is derived from the eponymous genus of spiders.
• Ms. Fanservice: Compared to almost every other Bognaarok, she's an absolute looker, looking very feminine despite her notably monstrous features. It helps that her design features Elegant Gothic Lolita elements alongside features that look quite similar to lingerie.
• Posthumous Character: It's initially not elaborated upon what became of her after she sealed Jeramie's powers 2,000 years ago, though Jeramie refers to the Venomix Shooter as a "memento of her", implying that she passed away prior to the series. #31 reveals that she was mortally wounded by the other Bognaarok ganging up on her after her fight with Daigorg.
• Purple Is Powerful: Features purple in her design, and is one of the strongest Bognaarok warriors.
• Spider People: She's themed on an orb-weaver spider.
  • Seductive Spider: Not so much in terms of personality, but definitely in her looks.

Jeramie Idmonaarok Ne Brasieri

Generals

Prime Minister Kamejim (spoilers)

Kamejim Unka

Portrayed by: Shin-ichiro Miki (voice), Masato Tsutamune (suit)

The Flamboyant

Habitat: Shugoddam (dark clouds)
Favorite: Insect fighting
King: Deceiver King

The chief minister of the Bognaarok Empire, and the brains behind the Kaijim. He is later revealed to be an agent of the Galactinsects and the true culprit behind the human-Bognaarok war under orders from his master.

---

• Alien Among Us: As it turns out, he's not actually a Bognaarok, but a Galactinsect agent and one of the Jesters the entire time.
• Big Bad Wannabe: For the ruthless manipulator he is presented as in maintaining the conflict on Tikyu while disposing of loose ends in the first half, Kamejim ends up being a low-level flunky compared to the other Galactinsects once they join the fray. Downplayed in being the only remaining Jester after the others were dispatched.
• Black Widow: While posing as Hymeno, Kamejim plots to select a suitor, preferably one of the King-Ohgers, and kill them after their marriage in stir chaos in Ishabana.
• Butt-Monkey: He quickly becomes the runt of the litter when the rest of the Galactinsects show up, as whatever competency he had in the first arc gave way to being comedically thrown around by the heroes and even his allies.
• Clark Kenting: While his disguises as humans are very accurate and effective, his disguise as a Bognaarok consists of...using the Bognaarok logo instead of the Galactinsect one. It works because no one except Racules actually knew about the Galactinsects, and if he knew, then he was in no position to tell anyone.
• Didn't Think This Through: Kamejim deliberately poisons Hymeno and her people with a substance from space, forcing her to be his captive while he ruled Ishbana by stating that only he has the cure. But he underestimated Hymeno, who simply created her own cure from scratch.
• Disc-One Final Boss: He seems to be set up to become the main antagonist of the second part but is driven off by God King-Ohger and is then revealed to be nothing more than one of the many Galactinsects Jesters, with the much more powerful Dugded serving as the main antagonist from that point forth .
• Double Reverse Quadruple Agent: He killed and replaced Boshimar to act as a double agent for Dethnaarok. However, it turns out he was actually a Galactinsect agent and one of the Jesters from the start.
• Dragged Off to Hell: After being killed by Rcules and Dethnaarok, Dethnaarok personally drags him off to be tortured in the afterlife.
• The Dragon: He serves as Dethnaarok's right-hand man. Or so he pretended, in truth he's one of many Co-Dragons to Dugded Durjarin. However, he winds up going back to this by the end as the only Galactinsect Jester left in the series finale.
• Even Evil Has Standards: Subverted. While he mastered the ages-long conflict between humans and the Bognaarok for his true master's amusement, he is disturbed by Dethnaarok's plan to completely destroy the planet yet is too afraid to directly stop him. In hindsight it was also probably less him objecting to it morally given his lack of them, but out of fear of what Dadged would do to him when he found out one of his planets was destroyed.
• Evil Counterpart:
  • To Rita. Both of them are the smartest of their respective factions, but while Rita is determined to maintain a sense of neutrality when dealing with political affairs, Kamejim has been manipulating the humans and Bognaarok for years.
  • To Hymeno, as both rule over Ishabana. But while Hymeno is a human who encourages people to better themselves and tends her subjects' health, Kamejim is an alien who manipulates others for his amusement and poisoned the Ishbanans.
  • To Jeramie as both have shaped Tikyu's history through the human/Bognaarok conflict. But while Jeramie sought atonement after realizing his prophecies made things worse between his parents' races, Kamejim remorselessly perpetuated the conflict for his amusement.
  • To Racules. Both are manipulators who managed a long-term plan for most of the series: Kamejim's role acting as Dethnaarok's right-hand is to bring upon his downfall to make way for the Galactinsect invasion. While Racules has been molding Gira to be strong enough to bring upon Dagded's downfall.
• Expy:
  • To Brajira, working for multiple villains as their righthand before revealing himself to have manipulated them for his own agenda. Bonus points in disguising himself as Boshimar like Brajira did in his Bredrun aliases.
  • To Deviot, being an insectoid Big Bad's deceptive general who served more than one group. He ultimately gets his boss killed with his former employee's surviving relative taking command of his forces.
• Eye Beams: He can fire blasts of light from his eye, which he uses to kill Karras in #30.
• Fantastic Slurs: He calls those beneath him "Insects".
• Faux Affably Evil: He appears to put up a polite front, but it doesn't change the tone of his own threats. He more or less instigated the main conflict between the humans and Bognaarok.
• Foil: To Jeramie. Both of them turn out to be a Treacherous Advisor to Dethnaarok who has Been There, Shaped History in regards to perpetuating the history of conflict between the humans and Bognaarok. However, Jeramie has had a Heel Realization in regards to the damage his actions have caused despite how unintentional it was, having wanted unity between the two races and worked to fix the situation the best he could, which heavily contrasts Kamejim's own attitude and actions, having deliberately maintained the destructive Cycle of Revenge in the name of the amusement of his true liege. This difference is most highlighted with their final interaction with Dethnaarok: after defeating him in head-to-head combat, Jeramie pleas for him back down and let go of his hatred for humans before he desperately tried to save Dethnaarok's life while Kamejim attacks Dethnaarok In the Back, mocks him as he reveals his manipulations before going on to kill him.
• Foreshadowing:
  • Kamejim looks very visually different from the rest of the Bognaarok, who tend to look much more insectoid while he barely resembles his insect basis. That's because he's not a Bognaarok at all, but a Galactinsect. When the rest of his kind finally shows up, he fits in much better with their designs.
  • In Episode 16, he enlists Wogerajim to kill Siron for unknown reasons before canceling the order upon deeming the human as harmless. It's later revealed he is an ally of the culprit behind the Fury of the Gods, Grodie Leucodium, and wanted to silence anyone who knew of Galactinsects' role in the engineered event since Siron's wife knew enough of the truth.
  • In #20, Kamejim explains to Dethnaarok that he justified his actions as The Mole in Racles' court as deceiving allies to best deceive enemies. Episodes later, he has Dethnaarok killed while outing himself as a member of the Galactinsects who manipulated both sides from the very beginning.
• Good Cop/Bad Cop: Dethnaarok doesn't bother with pleasantries and will threaten others to get what he wants. Kamejim is all about pleasantries, which consist of politely threatening others to get what he wants.
• Karmic Death: He gets killed by Rcles and Dethnaarok, whom he played and manipulated during their respective reigns.
• Kill and Replace: He killed the real Boshimar and assumed his appearance long before the series' events.
• Large Ham: He may look quiet, but there is a reason he is called "The Flamboyant" amongst the Galactinsects.
• Mad Scientist: In addition to his role as prime minister, he also serves as the Empire's head researcher.
• The Man in Front of the Man: He is revealed to have caused the human/Bognaarok conflict for his own amusement and then mortally wounds Dethnaarok when he no longer needs him.
• Master of Disguise: Similarly to Gerojim, he can assume the appearance of others.
• Meaningful Name:
  • His first name is derived from kamemushi (亀虫), the Japanese name for the stinkbug. The last two syllables are switched, and shi is changed to its voiced form, which allows him to match the rest of his comrades.
  • His last name is derived from Kiboshimaruunka (黄星丸浮塵子), the Japanese name for the Ishiharanus iguchi species of plant hopper, which has the ability to impersonate ladybugs.
• The Mole: To both Shugoddam (in his guise as Boshimar) and the Bognaarok, with his true allegiance lying with Dagded.
• Not Quite Dead: #27 reveals that he survived God King-Ohger's attack.
• Out-Gambitted: Disguising himself as Hymeno in #35 and #36, Kamejim expected to assassinate the team and kept her sword on him so he could claim her an imposter if she confronts him while using the cure to an unknown poison to keep her and her inflicted subjects in line. But Kamejim didn't count on Sebastian's interference as Romane or that Hymeno would prove herself as the real princess by curing herself and the Ishbanans with an antidote she made from scratch.
• Red Baron: He's known as "the Flamboyant" among the Galactinsect Jesters.
• Significant Wardrobe Shift: Downplayed. He switches the Bognaarok emblem on his head for the Galactinsect emblem after the other Galactinsects arrive and his true allegiance is revealed.
• Staff of Authority: He's second only to Dethnaarok in the Empire's pecking order, and carries a long staff dubbed the Mushimarupin. It's also the weapon he uses to kill Dethnaarok.
• Treacherous Advisor: He shows his true colors after he betrays Dethnaarok by impaling him with the Mushimarupin, explaining how he instigated the human/Bognaarok conflict, then leaves him to take a blast from a Kill Sat.
• Villainous Breakdown: In #36, not taking well to his plans falling apart while trying to maintain his charade as Hymeno in vain. In the Final Battle, nothing going his way has left him absolutely rabid. This soon fades into absolute terror as Dethnaarok prepares to land the final blow and then literally drags him to Hell.

Deathblow General Daigorg

Portrayed by: Kosuke Takaguchi (voice); Takuma Komori [episodes 17-18], Yohei Fujita [episodes 19-22, 31], Hajime Kanzaki [episode 23], Hirotsugu Mori [episode 41] (suit)

Habitat: Shugoddam (morning, noon, evening, night)
Favorite: Shugod souls
King: Giant King

A Bognaarok warrior who is regarded as the Underground Empire's hero.

---

• Back from the Dead: He presumably died sometime after the Bognaarok civil war, and was brought back to life in the present day using Shugoddam technology as part of the peace treaty between them and the Bognaarok. #31 reveals that his first death was by Nephila's hand.
• Blood Knight: He refuses to let anyone get in the way of a good fight, not even those who are supposed to be his allies.
• Boom, Headshot!: His fight with Nephila ends with her shooting him in the head at point-blank range.
• The Brute: He's the chief powerhouse of the Bognaarok, and serves as Dethnaarok's left hand.
• The Dreaded: Even the normally-unflappable Jeramie reacts with fear at hearing Daigorg's name.
• Half the Man He Used to Be: He meets his (second) end when he is cleft in twain from scalp to groin by King Caucasus Kabuto.
• Meaningful Name: His name is derived from daikokukogane (大黒黄金), the Japanese name for the horned dung beetle.
• One-Man Army: According to Jeramie, he won Dethnaarok the throne by single-handedly crushing all the opposition.
• Powerful Pick: His main weapon is a massive pickaxe dubbed the Daikocrusher. It's strong enough that the shockwaves it generates alone can cause massive damage.
• Red Baron: He's renowned in-universe as the "Deathblow General" (一撃将軍/Ichigeki Shōgun).
• Samurai: His overall design.
• Shout-Out: According to character designer Yuki Yogo, Daigorg's design was greatly inspired by Laomoto Khan from Ninja Slayer.
• Tough Beetles: He's themed on a horned dung beetle — the strongest insect on Earth — and has the strength expected of an enemy general, shrugging off Jeramie and Yanma's finishers with ease.

Gerojim

Portrayed by: Tomokazu Seki (voice), Kenya Saitō (suit)

Habitat: Shugoddam (daytime)
Favorite: Whisper Voice
King: Surprise King

A Kaijim infused with the BNA of a mayfly. While initially serving the Bognaarok cause, he becomes Jeramie's retainer after the king of the in-between saves his life.

---

• Ambiguous Situation: There are many ambiguous aspects about him presented over time, such as a half-Bognaarok nature like Jeramie as well as how he was able to survive all of his defeats, getting poisoned, and even consuming Shugod Souls, which should have killed him. He often hand waves it off as "being everything and nothing all at once" thanks to his Master of Illusion powers. It then gets Subverted when it is revealed that eating Shuggod souls causes memory loss with Gerojim luckily suffering Loss of Identity at worst.

• Ascended Extra: Originally presented as just another one-off Kaijim, he later becomes Jeramie's retainer after being rescued by him.
• Beware the Nice Ones: Gerojim is typically a Shrinking Violet, but when Jeramie's in a Heroic BSoD due to potentially having to cut down his kinsman Dethnaarok, Gerojim pretends to pull a Face–Heel Turn and puts on a very convincing performance: he convinced an entire platoon of Sanagim to help him out off-screen, attacks Jeramie outright and deconstructs his entire mindset in seconds. Thankfully, the whole thing was an attempt to pull Jeramie out of his funk. Not only does it work, but the exchange flags Gerojim as one of God King-Ohger's chosen pilots.
• The Consigliere: To Jeramie, with #25 showing that he's willing to call him out when necessary.
• Cover Identity Anomaly: Many of his disguises have visibly perfect appearances, yet stick out by how out of character they appear. Many others are too distracted or shocked to notice this.
• Energy Weapons: He can fire energy beams from his mouth and claws.
• Finishing Move: Yura Yu Rush: Gerojim unleashes a wave of immense heat at the target.
• Heel–Face Turn: Of sorts; he defects not to the monarchs' side but Jeramie's after the latter rescues him and helps fake his second death.
• Irony: Mayflies are known for having a very short lifespan of a single day after their larval state, yet Gerojim lives longer than the other Kaijim.
• Master of Illusion: His main ability is to use illusions to fool people, including disguising himself as other humans.
• Meaningful Name: His name is derived from the Japanese word for the mayfly, kagero (蜉蝣).
• Minion with an F in Evil: His track record in villainy is... less than stellar, to put it generously.
• Mistreatment-Induced Betrayal: His mistreatment at the hands of Dethnaarok combined with Jeramie sparing him causes him to become the first Bognaarok to defect to Jeramie's side.
• Never Hurt an Innocent: He has never hurt anybody on screen, even when he knocks Shiokara unconscious to replace him during Yanma's prank on Racules, Shiokara is still shown perfectly unharmed after waking up.
• Not Quite Dead: #13 reveals that he actually survived God Hopper's attack. He pulls this off again in the same episode with Jeramie's help.
• Pun-Based Creature: His Master of Disguise ability is based on the Japanese word for mayfly, which contains the phonetics for "shadow", kage (影).
• Put on a Bus: Hasn't been seen in-person during the middle part after Jeramie's Zero-Approval Gambit back in #29, only returning during the final arc.
• Shrinking Violet: He normally acts like this and speaks softly, due to being a Master of Disguise he claims no one would see him for who he is because he is a mere "shadow".
• The Unfought: He isn't given a full battle in his debut episode. Racules poisons him shortly after he makes his appearance to the monarchs and he gets one-shotted by God Hopper in his giant form... or so everyone thought.
• Wolverine Claws: Is armed with claws for melee combat.

Soldiers

Sanagim

Portrayed by: Unknown (voice), Various (suit)

The foot soldiers of the Bognaarok Empire.

---

• Abnormal Ammo: Rather than bullets, their rifles fire miniaturized Sanagim.
• Meaningful Name: Their name is derived from sanagi (蛹), the Japanese word for pupa.
• Mix-and-Match Weapon: Their primary weapon is the Gun Shovel, a polearm shaped like a spade that can be flipped around and used as a rifle.
• Mooks: They serve as the season's enemy grunts.
• Sizeshifter: They're able to grow to giant size, seemingly at will, in order to support their Kaijim counterparts. In addition, they can also be small enough for other Sanagim to use them as bullets for their guns.

Kaijim

The monsters of the Bognaarok Empire, created by Kamejim from his research of the Shugods.

---

• Contrasting Sequel Antagonist: The Hitotsu-ki were formed from ordinary humans corrupted by their own desires — which if strong enough could allow them to assume giant form, while the Kaijim are created by Kamejim, and assume giant form via ingesting an unknown substance.
• Kaiju: Despite starting out as human-sized monsters, as seen with Funjim during his introduction, the Kajim functioned as this due to being enlarged first before fighting the monarchs. This is later subverted in #5.
• Meaningful Name: Their name is a portmanteau of 怪人/ kaijin ("monster") and 虫/ mushi ("bug").
• Monster of the Week: As per Sentai tradition. This is averted in #10 by having every Kaijim fought up until that point revived at once as additionally-enhanced "Deth-Kaijims", and again in #17 and #19 with a Kaijim being brought back as an as-yet-unnamed higher tier.
