General Tropes

    Helheim Forest 

Helheim Forest

  • Alien Kudzu: Played for Horror — more than usual, anyway. Most uses of this trope have it as a symptom of an alien threat; Helheim is the threat. It's an unfeeling force of nature, and Nature Is Not Nice.
  • Arc Villain: Averted. Although the Helheim arc is named after it, the New Generation Riders continued to play the role of antagonist in it.
  • Assimilation Plot: Adds entire worlds to itself, converting all animal life in them into its Inves hordes.
  • Big Bad Ensemble: It shares the spot of the villain faction with Yggdrasill. It threatens to spread across the world, while Yggdrasill wants to contain it/exploit its power. Worse, it's revealed that Earth isn't its first victim and that it's actually sentient.
  • Blue-and-Orange Morality: According to its avatar Sagara, it only wants to bring about the next stage of evolution.
  • Don't Go in the Woods: Any normal human that enters Helheim runs the risk of getting killed by Inves or eating a Helheim fruit and turning into an Inves.
  • Eldritch Location: An unearthly forest filled with monsters and covered in alien plants that turn anything that eats them into more monsters. After The Reveal, it comes across as more like Eldritch Abomination. It spreads from planet to planet, dimension to dimension, overgrowing entire worlds and converting all animal life inside them into Inves.
  • Genius Loci: As revealed in episode #42 it's not only intelligent, it has an avatar in the form of DJ Sagara
  • Greater-Scope Villain: Though its presence is a looming threat that helps fuel the actual Big Bads, Helheim is never actually confronted by any of the Riders. Since it's a sentient forest rather than a single individual, it can't be directly fought.
  • Holding Back the Phlebotinum: In a sense. Helheim is a dangerous planetary threat but it lost all physical menace around #20 as its Inves had degraded to mere mooks in power leaving Yggdrasill as the main physical threat. Then the Overlords are revealed and it becomes obvious that Helheim has not been displaying its full might.
  • Humanity on Trial: According to Sagara, Helheim's invasion is a way to judge humanity's worth in some way.
  • Planetary Parasite: Overgrows entire worlds.
  • The Prophecy: It is said repeatedly that Helheim will someday "choose" a particular individual. What this means is unknown at the moment, except that The Chosen One could be any of the Riders.
    • DJ Sagara says that Helheim has a "forbidden fruit", and whoever gets it will gain great power. He says that Helheim grants evolution "to the ones worthy of ruling the world to come".
  • Walking Spoiler: Its true nature is this.

    Inves 

Inves

The Monsters of the Week summoned to fight in the Inves Game that dwell in the Helheim Forest. While the Inves Game is in action, they'll obey the one holding their Lock Seed and fight until ordered to retreat. However, should their wielder drop their Lock Seed, the Inves will go on a rampage and attack anything in sight. Some also emerge from dimensional tears that are opening to their dimension.

  • Airborne Mook: Eating unripe Lock Seeds cause the Mook Inves to sprout wings in #3.
  • Animal Motifs:
  • Black Blood: They seem to possess this. Strangely, the only times you see it are in a fight scene with Marika in #22, and when Baron pierces Demushu with an arrow in #26.
  • Blade Below the Shoulder: The Byakko Inves had them. The Komori Inves just has one.
  • Breath Weapon: The Seiryu Inves breaths blue fire.
  • Dark Is Evil: The Komori Inves.
  • Degraded Boss: Inves that act as Monsters of the Week often reappear as Mooks in later episodes. The basic Inves as a whole are demoted to Elite Mooks by the Forbidden Fruit Saga.
  • Energy Weapon: The Komori Inves can fire a BIG black laser beam when cornered.
  • Evolutionary Levels: Keeping with the Mons theme, the Inves evolve as they eat more Lock Seeds, starting out as Elementary Inves, then evolving into Berserker-State Inves, and finally into an Evolved Inves. If an Elementary Inves eats a whole lot of Lock Seeds it skips directly to an Evolved Inves. And now there are Overlord Inves, which makes every other character look wimpy in comparison.
  • Flight: The Komori Inves.
  • The Four Gods: The Byakko Inves from #1; The Seiryu Inves from #8. It's worth noting that these Inves are different from the other Inves, as they have armor that makes them look more like jade statues.
  • Home Field Advantage: Kouta notes that the Inves are stronger in the Helheim Forest and it shows with Gaim, Ryugen, and Baron having trouble defeating simple mook Inves.
  • The Horde: What the Inves can become when they get enough momentum going
  • Implacable Man: The Seiryu Inves in it's first appearance, afterwards the cast figure out how to kill it fairly easily.
  • Improbable Weapon User: The Long-Horned Beetle Inves uses its antenna as a whip in battle.
  • Law of Chromatic Superiority: The red Lion Inves is the strongest Inves encountered yet, needing Jimber Lemon Arms to be taken down.
  • Lightning Bruiser: The Evolved Shika Inves, the Seiryu Inves and the Lion Inves.
  • Make Me Wanna Shout: The Komori Inves.
  • Meaningful Name: #20 implies that Inves is short for the English phrase invasive species.
  • Mons: A Deconstruction of the trope, as while they're loyal so long as you hold the Lock Seed that summoned them, drop it and they'll go berserk. Uncontrolled Invase can also appear on their own, and they're disease carriers.
  • Monster of the Week: The Advanced Inves, although it's zig-zagged since they appear sparingly throughout the first arc and afterwards become more akin to Elite Mooks than the singular threat of an episode.
  • More Teeth than the Osmond Family: Those bulbous bodies on the Mook Inves? Those are all jaws.
  • Nerf: It is established in #9 that Inves summoned by Lock Seeds are much weaker than Inves that come into our world directly. Best shown with the mutated Komori Inves that could fight both Gaim and Ryugen at once and it explains why the Byakko and Seiryu Inves were so much trouble.
  • Nice Job Fixing It, Villain: The Lion Inves tearing off the Sengoku Driver's faceplate is what finally reveals the space for the Genesis Core.
  • No-Sell: The Seiryu Inves... until our heroes switch to blunt force weapons.
  • Not-So-Harmless Villain: In its first appearances, the Komori Inves got stomped by Ryugen and Gaim on two separate occasions - the mutated one in #9 can fight both of them at once.
  • One-Winged Angel: If one of the Mooks eats a mature Lock Seed, it becomes a full fledged Monster of the Week called a Berserker Inves. If one of those eats one, they turn into a giant monster called an Evolved Inves.
    • If one of the Mooks eats a whole lot of Lock Seeds at once, they will evolve straight into their Evolved State!
    • As #13 revealed, some Inves are this for humans like Ryoji. To clarify, humans can become Inves and gain more power, but seem to lose all sense of humanity, based off of how Inves-Ryoji was acting during #14.
  • Playing with Fire: The Shika Inves can do this, as well as the Seiryu Inves, followed by the Komori Inves.
  • Power Gives You Wings: The Lion Inves gains them after its Lock Seed malfunctions.
  • Primal Stance: The Evolved Shika Inves resembled a primate more than a deer.
  • Power Levels: Lock Seed classes play a vital role in how far the Inves evolves. Combining Lock Seeds also has that effect.
  • Red Right Hand: The three Inves that are confirmed to have been human once all had their right hands formed differently than their left. The Byakko and Bixie had large claws, and one Komori had a blade-like talon.
  • Technicolor Fire: The Seiryu Inves breathes blue fire as a sign of its power.
  • Villain Pedigree: The non-Mook Inves slowly become Mooks themselves. This culminates in #33, where an Overlord acts as a Monster of the Week in their place.
  • The Virus: Indirectly. Those injured by them seem to sprout or turn into Lock Seed plants, which in turn produce immature Lock Seeds capable of transforming people into more Inves.
  • Was Once a Man: Some of them anyway, with two cases confirmed (Yuya and Hase), one suspected (a worker in #9), and who-knows-how-many-more possible.


Overlord Inves

The Overlords are all that remain of the alien civilization known as the Femushinmu. They are an elite category of Inves that managed to retain their intelligence and receive great power from their transformation, capable of controlling lesser Inves and the Helheim Forest itself.

    General Tropes 
  • Aliens Speaking English: Subverted, they speak an alien language (though a cipher of Japanese). They have to learn Japanese, and even then they aren't Instant Experts except for Rosyuo.
  • Brilliant, but Lazy: They have godlike power, but don't really do much with it. Beyond just power, Redyue is able to grasp the basics of Japanese in just a few hours and Demushu follows shortly. Rosyuo masters Japanese fluently in the same amount of time.
  • Colorful Theme Naming: When translated from their Cypher Language.
  • Cypher Language: After their first major episode, fans were able to translate their language back into Japanese.
  • Disc-One Final Boss: They act as the main antagonists for the mid point of the show, but are defeated before the final act leaving the Kamen Riders themselves as the final villains.
  • Dying Race: By the time we meet them, only a handful are still alive, the rest having killed each other off a long time ago. By the end of the series, they're extinct.
  • Foil: Redyue notes that all Overlords are this to the Armored Riders. The Overlords survived Helheim by using its powers to permanently mutate into Inves, while the Armored Riders safely channel Helheim's power while retaining their humanity to conquer Helheim. Basically, the Overlords gave into Helheim while humanity conquered the forest.
  • Genocide from the Inside: The reason why there's so few Femushinmu in the present day is because the Overlords massacred the weaker members of their kind.
  • Go Mad from the Isolation: According to Redyue, living in the forest for so long has made them really, really bored. To the point where they attack Kouta and Kaito just to get some entertainment.
  • Godzilla Threshold: As a faction they are this. They are so powerful that them mobilizing causes every active Rider to team up to defeat them (except Micchy, who joins them). And their defeat causes to Riders to turn on each other again.
  • Green Thumb: They control the plants of Helheim the same way they control other Inves.
  • Hope Crusher: The Overlords are very good at inspiring fear, causing Heroic BSODs, and driving people past the Despair Event Horizon. The funny thing is that half the time this is happening on accident.
  • Human Aliens: Implied to be their original forms as Femushinmu, if the Overlord Queen and Lapis were anything to go by.
  • Ironic Nickname: Ryoma dubbed them the Overlords but in the end, they were just Helheim's pawns.
  • It Can Think: Unlike regular Inves, they were able to contain Helheim's power while keeping their mind. They can also still speak.
  • Monster Knight: They wear armor and carry weapons, setting them apart from their brethren.
  • Monster Lord: As their name implies, they can command lower Inves forms and are basically the rulers of Helheim.
  • Orcus on His Throne: It would probably take a lot less than ten years for Helheim to overtake Earth if the Overlords were leading its invasion, yet they seem content to just sit around doing nothing, letting the forest do all the work. On the flip side, they also don't care to restrain Helheim either. This is all justified, as Rosyuo doesn't want to take over Earth, but doesn't particularly care for humanity either.
  • Similar Squad: To three of the four main Riders, and Lapis from the summer movie is considered to be the fourth. Their colors and regional armor designs are an almost exact match, and their personalities aren't too far off either. While they could easily come off as a set of Psycho Rangers, the more complex morality at this point in the series means not all of them are evil while not all their Rider counterparts are good.
  • The Sociopath: Nearly all of them, save for Rosyuo.
  • Telepathy: They are able to communicate with each other through telepathy. Rosyuo in particular is also able to Mind Rape the others through this.
  • Time Abyss: How long they've been around is unknown, but, seeing as they survived the fall of their civilization, however long their civilization took to destroy itself, and for a long enough span of time that it's nigh impossible to tell Helheim was a civilized world at one time, they're most likely this trope.
  • Walking Spoiler: The fact that Helheim has "rulers" is a pretty big twist in the show.
  • Was Once a Man: Like all Inves, but Overlords somehow gained great power from Helheim instead of becoming mindless beasts.


    Demushu 

Demushu

Portrayed by: Tomokazu Sugita (voice), Daisuke Satō (suit)

https://static.tvtropes.org/pmwiki/pub/images/deemushu_inves.png
Demushu Evolved Form 

The first Overlord-class Inves introduced. Demushu is bellicose and armed with a formidable array of powers.


  • Annoying Arrows: Shrugs off Baron's Lemon Energy arrow, though it leaves a scar.
  • Arc Villain: Can be seen as this for the Overlord Saga, as his arrival kicks it off and his demise ends it.
  • Authority Equals Ass Kicking: Demushu is the Overlord that shows us why they are on the top of Helheim.
  • Ax-Crazy: He's short tempered, violent, and when he loses his cool bad things happen.
  • Badass Cape: A rather regal one to contrast his thuggish demeanor.
  • BFS: Fights with one.
  • Blood Knight: Seems to be all he lives for.
  • The Brute: War and death are all he thinks about. Ironically, he is the weakest of the main three Overlords, being effortlessly defeated by Kouta's Kiwami Arms. Putting this in perspective: Redyue can fight against it to a standstill, while Rosyuo is perfectly able to curbstomp it.
  • Colorful Theme Naming: "Demushu" translates to "Shinku", or "Crimson".
  • Curb-Stomp Battle: Kaito didn't even get one clean hit in #23. Neither does Kouta in #24.
    • Finally ends up on the receiving end once Kouta accesses Kiwami Arms in #32.
  • Evil Counterpart: To Baron. Both are red, have a European armor themed design, and are characterized by their drive for power. Demushu embodies the kind of powerful individuals, who gleefully and freely trample the weak underfoot, that Kaito seeks to rid the world of.
  • Evil Laugh: Usually does this when he's hurting someone.
  • Evil Sounds Deep: The first Overlord to be shown and starts the tradition of them having deep, powerful voices.
  • For the Evulz: On top of his envy, Demushu freely admits he enjoys hurting people for the sake of hurting them.
  • Green-Eyed Monster: When asked why he begins destroying the city with no provocation, he replies that he hates humanity for still having what his species has lost.
  • Hair-Trigger Temper: He's the most violent and badmouthed of all Overlord Inves.
  • Hate Sink: He is a vicious warmongering Blood Knight Overlord Inves who desires to imperil others he deems weaker than him and can easily be vexed at what he considers anything to be an insult to him.
  • The Heavy: His love of war and vendetta against Kaito make the Overlords take more interest in Earth, kicking off their invasion.
  • Hot-Blooded: To psychopathic levels.
  • Implacable Man: In all of his fights he's fought multiple Riders in succession and keeps going, even when his opponents tag out or have had a chance to recuperate while he hasn't.
  • Jerkass: Demushu is a rude, vicious, violent thug, and that's all there is to him.
  • Kick Them While They Are Down: Does this with sadistic glee in #31.
  • Killed Off for Real: With the debut of Kiwami Arms in #32.
  • Knight of Cerebus: Demushu has always been bad news but when he escapes to Earth he effortlessly destroys The Masquerade and begins the shows Darkest Hour.
  • Large Ham: He's like a Japanese Lord Zedd.
  • Magic Knight: A hulking knight monster that has a plethora of mystic powers to compliment his martial strength.
  • The McCoy: He's a raging low-functional sociopath to contrast Redyue's spockish psychopathy and Rosyuo's sanity.
  • Nice Job Fixing It, Villain: His Roaring Rampage of Revenge against Kaito caused Takatora to become aware of another way to save humanity, causing him to support Kouta.
  • Omnicidal Maniac: His social Darwinism reaches this level. He just wants people to hurt, subjugate, and kill each other until there's only one last man standing.
  • One-Man Army: Levels city blocks easily and can fight six Kamen Riders at once.
  • One-Winged Angel: His Evolved Form.
  • Playing with Fire: His main magic offensive.
  • Pride: His ego seems to trump even Kaito's.
  • Roaring Rampage of Revenge: Goes ballistic when Kaito wounds him, killing everything he can get his hands on while trying to find him.
  • Proud Warrior Race Guy: Deconstructed. His pride in his combat prowess just shows that he's nothing more than a monstrous sadist.
  • Sadist: It becomes obvious that Demushu likes the "hurting people" part of combat much, much more than the "fighting people" part.
  • Shoulders of Doom: Gains these after getting his One-Winged Angel form.
  • Super Smoke: Seems to be able to turn into this to quickly move around and attack.
  • Super-Toughness: While it harmed him, taking a direct hit from Kaito's Lemon Energy finisher did a lot less damage to him than one would expect.
  • Scars are Forever: Retains a large scar that Kaito gave him during their second battle.
  • Shadow Archetype: Is this to Kaito, who's visibly disturbed at one point by one of Demushu's rants about power. Notably, when Kaito becomes Lord Baron, he heavily resembles Demushu.
  • Sir Swears-a-Lot: He sure likes the word "bastard".
  • Son of an Ape: Refers to humans as 'apes' whenever he talks to them.
  • Social Darwinist: To omnicidal extremes.
  • Sorcerous Overlord: Pun aside, Demushu wields a tremendous amount of magical(?) power in addition to its physical skill with a sword.
  • Teleport Spam: Uses this tactic whenever he's calm.
  • This Cannot Be!: His reaction to losing to Kouta.
    Demushu: This can't...this can't be! I can't lose...to you pathetic apes!
  • Villainous Breakdown: Does not take being wounded by Kaito well.
  • Wake-Up Call Boss: He is the weakest of the main three Overlords, but defeating him still required The Hero to accept nearly godlike powers. This shows the series is really upping the ante in terms of power levels.
  • War Is Glorious: Holds this mindset; it helps to show how horrible a person he is.
  • We Come in Peace — Shoot to Kill: The package containing a Japanese dictionary and a pioneer plaque (with an Inves added in the diagram) shows that Kaito is willing to try communicating with the Overlord before anything else. Unfortunately, Demushu isn't having any of it, and the gesture simply enrages him.

    Redyue 

Redyue

Portrayed by: Kenjiro Tsuda (voice), unknown suit actor

https://static.tvtropes.org/pmwiki/pub/images/krga_redyue_0.png

The second Overlord-class Inves. Eerily similar to Ryugen in color and design. Redyue is calmer and much more intelligent than Demushu, but is no less malevolent, wanting a 'toy' to alleviate the boredom of existing in Helheim for so long.


  • All Your Base Are Belong to Us: In #32, Redyue has Helheim infect Yggdrasill tower, turning it into the Overlords' main base of operations on Earth.
  • Admiring the Abomination: Inverted: the childish, sadistic Redyue reacts with glee when she sees how ruthless humans are when the world governments try to nuke Zawame City just to have a chance to kill her.
    • Also inverted with Micchy. She finds his madness to be the most interesting thing it the world.
  • Arc Villain: For the Forbidden Fruit arc. While Rosyuo is the leader of the Overlords, Redyue is the leader of their invasion of Earth and was an evil monster long before Rosyuo ruined their world.
  • Ax-Crazy: She hides it better than Demushu, but this bitch is fucked up in the head.
  • The Baroness: A textbook Rosa Klebb: cunning, sadistic, and aggressively desexualised.
  • Bastard Understudy: She serves Rosyuo, but is just biding her time to get the Forbidden Fruit from him. The reason she helps him with the scheme to revive the Overlord Queen is so he'll pass on the Fruit to her.
  • Batman Gambit: All of #34 was a magnificent one of hers. By declaring war on humanity, she got them to try and use some ICBM's to kill her, which in turn forces Rosyuo to get off his throne and act as a deterrent to future incursions, while at the same time bringing a good portion of humanity past the Despair Event Horizon once they see how powerful the Overlords are.
  • Big Bad Duumvirate: After taking Micchy under her wing, she forms a partnership with him and together they serve as the main villains of the "Forbidden Fruit" arc, although Redyue is by far the more dominant one.
  • Big Bad Ensemble: Shares this position with Ryoma, particularly during the Forbidden Fruit Saga where she acts as the Inves invasion's military leader and becomes the de facto Big Bad for a time, after which Kaito takes over in the final arc.
  • Break Them by Talking: Tries to break everyone she talks too, but #41 was pretty much her being this trope with a heavy dose of Mind Screw.
  • The Chessmaster: "Everything is moving as I desired."
  • Chronic Backstabbing Disorder: And proud of it.
  • Colorful Theme Naming: "Redyue" translates to "Hisui", meaning "Emerald" or "Jade".
  • The Corrupter: To Rosyuo. After she begins scheming he becomes much more villainous. She's also this to Mitsuzane, finishing where Sid left off, wanting to complete his transformation into a complete and total villain so they're exactly alike.
    • She tries to be this to Kouta in #40. It doesn't work, but she got closer than anyone else.
  • Creepy Monotone: Her contralto is always clipped and emotionless.
  • Combat Pragmatist: Makes up for her physical weaknesses by using Helheim fauna traps and by using the terrain for cover.
  • Curb-Stomp Battle: Considering all the crap she's put everyone through, it's actually almost disappointing how quickly Kouta took her down. Almost.
  • Dark Action Girl: Capable of fighting Kiwami Arms and is quite possibly the most dangerous Overlord in terms of her threat to humanity.
  • Despotism Justifies the Means: Redyue wants to take the Forbidden Fruit just to be king and wants to conquer Earth because she thinks it will be a nice new toy.
  • Distaff Counterpart:
    • She's Mitchy if he let go of all his morals.
    • Also one to Ryoma as well, both being the manipulative Evil Geniuses of their factions who plot against their leaders.
  • The Dragon: The one Rosyuo entrusts to command Earth's invasion for him.
  • Dragon-in-Chief: While Rosyuo is the leader of the Overlords and technically much more powerful than her, he can hardly be arsed to do much, while Redyue is the one that's actually motivated to conquer Earth, and the one who commands the invasion and comes up with evil schemes, making her the de facto Big Bad.
  • Evil Cannot Comprehend Good: The idea Kouta might be selfless enough to care about the people of the world more than himself or ruling the world never occurs to her. As a result, her attempt to tell him We Can Rule Together blows up in her face by convincing Kouta to be willing to give up his humanity to fight the Overlords and save the world, ultimately resulting in her demise.
  • Evil Chancellor: Acts as Rosyuo's advisor in what's left of his Decadent Court. She plots to usurp him too.
  • Evil Counterpart:
    • To Ryugen, which is quite a feat at this point. Both are primarily green, have a Chinese armor themed design, and are insanely (as in literally insanely) manipulative.
    • She is also one to DJ Sagara. He appeals to Rosyuo's morality and wants him to give humanity a chance, while Redyue tries to tempt him into complete villainy.
  • Evil Feels Good: Gives an entire speech about how ruining peoples lives is the most satisfying thing to do.
  • Evil Genius: Fills this role for the Overlords. She's highly intelligent and shows herself to be a capable inventor, with her quickly mastering Earth's sciences and figuring out how to fuse it with the Overlords' own technology to create a machine capable of reviving the dead. She's also adept at learning new languages, as she picks up Japanese in less than a day. And she's incredibly cunning and manipulative on top of that.
  • Evil Laugh: Whenever she finds a really interesting new toy.
    • Really rips an epic one when she finally betrayed Rosyuo.
  • Evil Mentor: To Micchy. She wants to transform him into someone who's on "her level" as she puts it.
  • Evil Sounds Deep: A Rare Female Example. That's what happens when you get a male voice actor to voice a female despot.
  • Faux Affably Evil: She always speaks in a soft spoken and controlled manner even when committing genocide.
  • The Final Temptation: Gives this to Kouta in #40 by telling him the humans will no longer accept him now that he's an Overlord and that he should join her in ruling the planet.
  • For the Evulz: Redyue lives by this trope. She flat out admits that the reason why she does anything is because she loves breaking people.
  • From Nobody to Nightmare: She was once a village girl. Now she a monstrous sadist that is one of the greatest threats Earth has ever seen.
  • Glass Cannon: Redyue is very fast, competent enough in close combat, and has enough destructive power to rival Kiwami arms, but compared to the rest of the Overlords she doesn't tank damage very well.
  • Hate Sink: She is malevolent Overlord, wanting to wanting a 'toy' to alleviate the boredom of existing in Helheim for so long and is plain manipulative in general.
  • The Heavy: Takes the role from Demushu after Rosyuo gives the official order to attack Earth, becoming the main face and power of Helheim's first actual military assault, giving the invasion a proper leader.
  • Human Resources: Begins kidnapping humans to power a device that will revive Rosyuo's Queen at the cost of God knows how many human lives.
  • I Gave My Word: Promises Micchy that she won't hurt any human chosen for his version of Project Ark. She breaks her word, but Micchy, being Micchy, doesn't care, thinking that they deserved it.
  • I Let You Win: Threw her fight against Sid and Micchy in #31 so she could lead them to Rosyuo and have him kill the two.
  • Intrigued by Humanity: Seems so. The girl not only learned Japanese in what amounted to a day or a few days, but also seems to be the most fascinated by humans in general, especially when compared to her counterpart.
  • In the Back: How she starts her murder of Rosyuo.
  • It Amused Me: Seems to be more this than Demushu. While she does enjoy suffering, she seems to see no difference between learning Japanese and seeing a human beaten up so long as it alleviates her boredom.
  • Last of His Kind: She becomes the sole remaining Overlord after killing Rosyuo. For about one and a half minutes, anyway.
  • Mad Scientist: And it took her less than a day to get a doctorate in morally bankrupt science.
  • Magitek: All of her mad science is created by combing Yggdrasill tech with her species mysticism.
  • Manipulative Bitch: She's the master manipulator Micchy thinks he is. Every scene she's in she's manipulating someone: Rosyuo, Kouta, Micchy himself, the governments of the world.
  • Meaningful Name: Redyue is Overlord speak for Jade. Not only does she look like a jade statue, but all of the Green Inves seen have a jade statue feel to them, with Hekija having a brass coloring.
  • Meet the New Boss: Takes the reigns from Demushu as the main antagonist and proves to be infinitely more monstrous than he ever was.
  • More Deadly Than the Male: The only confirmed female of the Overlords and is also the most sadistic and monstrous of the species, taking over from Demushu after his death, and proving to be far worse than he ever was.
  • Necromancer: Creates a machine that can revive the dead.
  • Nerves of Steel: She keeps her cool, even when she's overpowered.
  • Nice Job Fixing It, Villain: In #40, Redyue tried to get Kouta to give up his humanity and join the Inves side. It backfired on her spectacularly when not only does he not join her, him giving up his humanity granted him Overlord power - power that Kouta used to kill her. To make matters worse, Kouta prior to that point had huge doubts about himself after what happened with Yuya. Redyue pretty much just gave Kouta the means to finally move on from Yuya's death and allowed him to gain an unwavering resolve.
  • No-Holds-Barred Beatdown: She kills Rosyuo by beating him to death.
  • Obfuscating Stupidity: Pretends to be a G1 Starscream in competence when she is actually a Cybertron level one.
  • Out-Gambitted: By Rosyuo.
  • Practically Joker: She is an anarchist who loves to see the world burn and people suffer in despair. She is not above Mind Rape and is a Psychopath who laughs and is colored green she is basically Kamen Rider's answer to The Joker as well as Green Goblin.
  • Psychopathic Womanchild: Type C. An intelligent sophisticated being that treats humans like they're her newest toys. Also has traits of Type E, as she seems to see little difference between learning Japanese and seeing a human hurt.
  • Red Eyes, Take Warning: This trope even sounds like her name.
  • Reminiscing About Your Victims: She enjoyed telling the story about how she killed her entire family way too much.
  • Secondary Color Nemesis: Her palette is a mix of shades of green, mostly jade, and she's the worst of the Overlords.
  • Self-Made Orphan: She killed her entire family for fun stating that it was one of the most satisfying things she ever did.
  • Serial Killer: Started out with killing her family and given how many "toys" she has played with, it's obvious that she didn't stop there.
  • The Smurfette Principle: The only female Overlord revealed thus far.
  • Soft-Spoken Sadist: Speaks quietly and calmly, finds great pleasure in watching Kouta get beaten to a pulp and admits that her greatest joy in life is when one of her toys die from despair.
  • Super-Intelligence: Mastered most of Earth's languages in a couple of weeks and managed to adapt near-future Earth technology (which was way beyond her civilization's tech-level) into a machine capable of raising the dead in a matter of days.
  • The Spock: Of the soulless sociopath variant.
  • The Starscream: Micchy suspected the reason she led him and Sid to the Forbidden Fruit was to kill Rosyuo. She could then finished off the duo and have the Forbidden Fruit for herself. This fails, considering it's Rosyuo.
    • Later played straighter when she literally stabs Rosyuo In the Back to steal the Golden Fruit for herself. Unfortunately, since Rosyuo had already bequeathed the majority of its power to Mai, this turns out to be all for naught when all Redyue gets is a rotten husk. She takes this rather badly.
  • I Surrender, Suckers: An odd example. Redyue surrenders, but doesn't strike back. Instead leading her opponents to Rosyuo so that he can kill them. She gets interested when one of them refuses to go and cites it being a trap.
  • This Cannot Be!: Her last words before Kouta finishes her off for good.
  • Take Over the World: Wants to conquer Earth for herself solely because she's begun to find Helheim boring and wants to see what its like to rule a concrete jungle.
  • Uriah Gambit: Tricks Sid into fighting Rosyuo to see what would happen.
  • Victory Is Boring: Because there are no more lives to ruin.
  • Villain Takes an Interest: Yet another villain that finds Micchy interesting; this will not end well.
  • Villainous Breakdown: After backstabbing Rosyuo and finding out the "Golden Fruit" she took from him was a withered husk. She goes utterly berserk, in direct contrast to her normal calculating demeanor.
  • Vocal Dissonance: Redyue is officially female, but she doesn't sound like one.
  • We Can Rule Together: Offers Micchy a chance to become her right hand man so he can control humanity while she toys with it. He accepts.
    • Also attempted to do this to Kouta, stating that no mater what he does, humanity will reject him in the end. He tells her where to stick it.
  • Women Are Wiser: Both the only female Overlord and the smartest by far, capable of feats of outright Super-Intelligence.

    Rosyuo 

Rosyuo

Portrayed by: Joji Nakata (voice), Yasuhiko Imai (suit)

https://static.tvtropes.org/pmwiki/pub/images/krga_rosyuo_7.png

A white-colored Overlord. He is Demushu and Redyue's superior and the "King" of the Overlords, and by extension of Helheim and the Inves.


  • Affably Evil: To the point where he isn't even really evil.
  • Anti-Villain: Isn't really evil anymore, having long abandoned his Social Darwinist philosophy. He doesn't want to destroy mankind, he merely thinks giving them what could save them would be a wasted effort, as he believes they're no different from his kind and would only destroy themselves with it. Even then, he's willing to give them a chance to prove him wrong.
  • Armor-Piercing Question: Gives one to Takatora.
    Rosyuo: Is that tool there for defending the weak? Or will it tempt the strong to sin?
  • Asskicking Leads to Leadership: He fought his way to the top of Helheim. He's in charge for a reason.
  • Authority Grants Asskicking: Annihilates Sigurd without needing to lay a hand on him.
  • Bad Boss: Justified. His subjects are all violent psychopaths, so he makes an effort to keep them on a very short leash. Takatora could learn from his management style.
  • Bad Guys Do the Dirty Work: He kills Sid, doing pretty much everyone a favor. Sid really shouldn't have tried to pick a fight with a demigod.
  • The Bad Guy Wins: He was his world's answer to Kaito, and conquered the planet with Helheim's power. He wishes he hadn't.
  • Being Evil Sucks: Is perfectly aware that being an all-powerful Evil Overlord is a worthless endeavor that has left him with nothing but death and destruction.
  • Beware the Nice Ones: Isn't a bad guy really, and while brutal on his minions, it's more because he needs to be than because he wants to be. He even saves Takatora's life and lets him stay with him. However, while he does offer Sid a chance to save himself, when he doesn't take it, he dishes out one of the most brutal Rider deaths ever.
  • BFS: Occasionally carries a huge sword.
  • Boomerang Bigot: He hates his own species. Not hard to see why.
  • The Chosen One: He was the one chosen by Helheim back in his cycle and now acts as the guardian of the Forbidden Fruit
  • Colorful Theme Naming: "Rosyuo" translates to "hakua", meaning "chalk".
  • The Cynic: Believes that Humans Are Bastards and will turn out just as bad as his species did.
  • Deconstructed Character Archetype: Of the common depiction of The Social Darwinist. As revealed in Rosyuo's backstory, he used to believe that only the strong were worthy of living in the world he would create while the weak were only fit to be used in whatever way they deemed fit, and due to winning the Golden Fruit, he was about to turn his personal philosophy into actual law for his subjects to follow. The end result was his race hunting each other down until about five were, turning their world into the desolate ruins seen in the modern day. Rosyuo has had many years to realize the inherent foolishness of those beliefs and now has to live with the fact that he caused the end of his race, not Helheim, until the end of his days.
  • Dimension Lord: As Man of the Beginning, he rules over the Helheim Forest dimension.
  • Don't Make Me Destroy You: Tells Sid to just turn around and leave so he won't have to kill him. Sid doesn't take it, and Rosyuo keeps his word.
  • Do Not Taunt Cthulhu: Despite his redeeming qualities and generally being more of a guardian than a villain, he is not someone you want to piss off. Just ask what's left of Sid. He even offered him a chance to just run, which he didn't take.
  • The Dreaded: He makes sure his vassals have a healthy fear of him.
  • Empty Shell: Redyue describes him as one, and she's not exaggerating by much - he's well past the Despair Event Horizon, with no motivation other than to resurrect his dead wife.
  • Evil Overlord: Deconstructed and justified. Rosyuo beat his way to the top of Helheim's food chain and now rules with an iron fist. In doing so, he now rules over an empty shell of a world, and has lost everything but the most cutthroat of his followers. Rosyuo really isn't evil anymore, but all of his remaining subjects are murderous psychopaths so he acts as a ruthless despot to keep them in line.
  • Evil Sounds Deep: It's Joji Nakata voicing a toku villain.
  • Face Death with Dignity: Even when Redyue's stabbing him and beating the stuffing out of him, Rosyuo barely reacts, just telling his love he will be with her soon.
  • Family-Unfriendly Death: Rosyuo had a hole blasted through his chest, was then beaten to death by Redyue, who then stabbed his corpse over and over again after learning that he didn't have the Forbidden Fruit. How did Urobuchi get away with that?note 
  • Fallen Hero: Rosyuo originally wanted to save his world from Helheim.
  • Fertile Feet: Helheim plants grow where he walks, fitting for Helheim's Chosen One.
  • Foil: To Zangetsu. Both are white, resemble samurai, are on another level than the Riders/Overlords shown before them, and while they aim for their goals, they get undermined by their subordinates' own plans. The main difference is in their level of cynicism - Takatora was cynical enough to use questionable methods to save humanity, but Rosyuo is a nihilist who thinks we'd be better off receiving a collective Mercy Kill before we wipe ourselves out.
  • Good Angel, Bad Angel: DJ Sagara is his good angel, while Redyue is the bad angel.
  • Good Is Not Soft: He's easily the least malevolent Overlord in the series and was nice enough to save Takatora's life and let him stay with him. He also generally tries to keep his minions in line, and even offered Sid a chance to just leave with his life. However, when Sid didn't take it, Rosyuo killed him. Brutally.
  • Good Running Evil: Zig-zagged. He's long since stopped being evil and regrets his past actions, but considering his remaining subjects are all violent barbarians, he has to show force every once in a while to keep them in line, and the death of his wife and downfall of his entire civilization have left him without much motive to do anything.
  • Hidden Depths: Takatora is found and patched up by Rosyuo, who tells him about the former inhabitants of Helheim. Furthermore, Rosyuo appears to have genuinely loved his queen and wants to bring her Back from the Dead.
  • Hidden Heart of Gold: Rosyuo goes out of his way to nurse Takatora back to health, defends him from Sid, and genuinely loved his wife. He bears no malice towards humanity, but is so burned out and nihilistic he is initially unwilling to save them either.
  • Humans Are Bastards: Is of this opinion, believing they're just as power hungry and monstrous as his species was. He believes the Forbidden Fruit would be wasted on them and even if they got it, they'd only destroy themselves with its power. However, he's still willing to give Sagara a piece of the Forbidden Fruit to test Kouta to see if he's worthy. So while he believes this trope is true, he's still willing to give them a chance. And he does.
  • Impaled with Extreme Prejudice: Redyue kills him by stabbing him from behind.
  • It Is Beyond Saving:
    • In #35, after seeing that humanity is perfectly willing to nuke a city filled with innocent people just to kill two Overlords, he writes humanity off as a lost cause and unleashes the full might of Helheim onto Earth.
    • He's also of this opinion about his own race, and part of his belief humans will just kill themselves off if they get the Forbidden Fruit is that that's exactly what his kind did. While he can't resurrect the dead, he's more than capable of creating new life however he chooses, but would rather just let his species reap what they've sowed and die out.
  • The Juggernaut: Before we even see him fight, we're shown the ridiculous levels of power he has access to, with complete control of both the inves and the cracks on a global scale, as well as being able to freeze a huge barrage of missiles in mid air before teleporting them to the other side of the planet where they proceeded to take a chunk out of America. When he finally goes up against Gaim and Baron after he gave away the forbidden fruit to Mai, it's almost laughably one-sided. He hits harder than both of them put together, his telekinesis means he can throw them around like ragdolls and the one solid hit that does land doesn't seem to hurt him and heals almost instantly. Then he goes one on one with Kiwami and just annihilates him. The only thing that saved Gaim was Rosyuo and Redyue's backstabbing.
  • The Kirk: The only Overlord that is rational or sane.
  • Laser-Guided Karma: Though saddened by their deaths, he admits that the Overlords that died deserved what they got which is why he doesn't hate humanity for it.
  • Last-Second Chance: After a talk with DJ Sagara he decides to give humanity a chance to prove that they're not as horrible as his species was.
  • The Lost Lenore: His dead queen, who he's shown to still pine for and keep her coffin in sight of his wrecked throne room. He also desires to bring her back to life.
  • MacGuffin Guardian: Is the guardian of the Forbidden Fruit.
  • Meaningless Villain Victory: He succeeded in becoming Helheim's ruler and establishing the Darwinistic society he envisioned, but the steps it took to there, the loss of his civilization, and the death of his beloved wife have left him a broken man.
  • Mind over Matter: Has extremely powerful telekinesis, enough to literally split mountains.
  • Mind Rape: Does this to Demushu while talking to him telepathically in #27.
  • Mirror Character: To Takatora. Both are associated with the color white and both are well-meaning figures in charge of villainous factions.
  • Misanthrope Supreme: Hates both his own species and humanity, thinking that when faced with adversity the weak ones will become cowardly backstabbers while the strong become violent despots.
  • Necromantic: Rosyuo's main goal is the revival of his Queen, who died at some point prior to the series.
  • No Body Left Behind: Averted. An oddity for a Kamen Rider monster, Rosyuo doesn't explode when he dies and leaves behind a corpse. Also Justified as he did not die to a Rider finisher charged with energy.
  • Nothing Personal: He bears humanity no ill will and doesn't hate them for any Overlords deaths.
  • Only the Chosen May Wield: Firmly believes this about the Forbidden Fruit and refuses to give it over to anyone else. He eventually chooses Mai.
  • Only Sane Man: For the Overlords. He's the only one who realizes that how horrible the species has really become.
  • Orcus on His Throne: Justified once more. Rosyuo doesn't want to destroy the Earth but his vassals do, so he uses all of his power to keep them off the game board.
  • Pet the Dog: He agrees to Micchy's request to guard Mai from Redyue.
  • Physical God: Presumably, considering he obtained the Forbidden Fruit. What we've seen of him only supports the possibility. However, his power does have limits, as he laments that even with all he power he can do nothing about death.
  • Power Floats: When he wants to make people fear his power.
  • Red Baron: King of the Overlords.
  • Reasonable Authority Figure: As long as you aren't Demushu, Redyue, or Micchy, he'll listen to you and hear you out.
  • Sacred Hospitality: He doesn't take kindly to people attacking people he's nursing as Sid discovers.
  • Secret Test of Character: His entire fight with Kaito and Kouta was a test to see their moral character.
  • Shadow Archetype: He is what Kouta would have been had he failed in the final battle, a bitter, miserable shell of himself surrounded by monsters and having lost the love of his life. He's also one to Kaito—if Kaito had won, he'd have become a second Rosyuo.
  • The Social Darwinist: What he once was; the new world that he created was based on these rules and only the strong survived, but these remaining inhabitants ended up destroying each other, with Rosyuo and his Overlord vassals being the only remaining members of their species.
  • Super Power Lottery: Fitting for the World's Strongest Man Rosyuo can fly, has mountain shattering telekinesis, can teleport, is a Master Swordsman, can manipulate electricity and blue fire, has a powerful Healing Factor, has complete control over Helheim, and can create life.
  • Sympathy for the Devil: He mourns the deaths of all of the deceased Overlords, even though he knows how horrible they all are.
  • Sympathy for the Hero: When meeting with Takatora and Kouta he is nothing but sympathetic to the suffering they endured.
  • Take Up My Sword: After he dies, Kouta literally takes up Rosyuo's BFS and uses it to give Redyue an extremely satisfying beatdown.
  • Token Good Teammate: He's the only Overlord who's halfway decent.
  • Villain Takes an Interest:
    • He takes an interest in Takatora and nurses him back to health after finding him injured. He seems to respect Takatora as a fellow leader for his people and takes time to impart some advice onto him before letting him go once he's recovered.
  • Villainous Rescue: Saves the day in #34, when the world governments try to nuke Zawame City he puts an end to that plan in the most awesome way possible.
  • Was It Really Worth It?: No. No it wasn't, and Rosyuo is completely aware of it.
  • What You Are in the Dark: He stole humanities' Forbidden Fruit and had a chance to revive his Queen with it, but after a talk with Sagara he decides to give humanity a second chance.
  • Who Wants to Live Forever?: Has outlived his mate and his entire civilization, having had a long time to think about what he's done and has come to regret it.
  • Worf Had the Flu: He was fighting the heroes with just a husk of the Forbidden Fruit, having given the rest to Mai. Yes, the utter curbstomping he gives Gaim and Baron was him weakened. This is also probably why Redyue was able to kill him period.
  • World's Strongest Man: And that's before the Forbidden Fruit comes into the equation.
  • Zen Survivor: He's the only two character that can be considered wise in the show and became that way through countless years of suffering.

Portrayed by: Hiromi Iwasaki

https://static.tvtropes.org/pmwiki/pub/images/overlord_queen.png

The deceased wife of Rosyuo, who originally granted the Golden Fruit to him. Rosyuo is desperately trying to resurrect her.


  • Human Aliens: She's the queen of an alien species but looks rather human.
  • Posthumous Character: She's dead but is a major part of Rosyuo's character arc.
  • Red Eyes, Take Warning: Has red eyes that signifies her status as her cycle's Women of the Beginning.
  • Together in Death: She promises this to Rosyuo as she kneels over his corpse before disappearing herself.

    Minor Overlords 

Dyudyuonshu

Portrayed by: Yoji Ueda (voice)

https://static.tvtropes.org/pmwiki/pub/images/krga_dyudyuonshu.png
  • Affably Evil: Compared to the rest of the minor Overlords.
  • Avenging the Villain: States part of the reason he wants to see Kouta dead is to avenge Demushu.
  • Breath Weapon: He has fire breath, to be exact.
  • Combat Pragmatist: He set up a trap to lure Kouta into ahead of time.
  • Cool Sword He can even deflect lasers with it, Jedi style.
  • Feathered Fiend: He is based on a phoenix.
  • The Handler: Micchy notes that he's this to him. Which is why he gets killed.
  • Human Shield: Inves Shield. Zangetsu Shin uses him as this in #33 to escape Gaim's finisher, resulting in the Overlord's death.
  • Meaningful Name: His name translates to Suzaku.
  • Monster of the Week: Justified for three reasons. First, he's a minion of Redyue. Second, Kouta's Kiwami Arms make him as powerful as an Overlord. Third, Micchy wanted him to die because he was his handler.
  • True Companions: A rather twisted version of the trope, and not just because he's a villain. He wants to avenge Demushu by killing Kouta and states that the death of a human is nothing compared to the death of an Inves, though the real cake comes in #40 where, in the dreamworld that Redyue makes, he and a Seiryu Inves hold off Zack and Minato so that Kouta can run off and rendezvous with Redyue and Shinmugurun, explicitly telling Kouta that his fellows await.
  • We Hardly Knew Ye: Only got two episodes and in one of them he was already dead.

Grinsha

Portrayed by: Yuki Anai (voice)

https://static.tvtropes.org/pmwiki/pub/images/krga_grinsha.png

Shinmugurun

https://static.tvtropes.org/pmwiki/pub/images/over_lord_shinmugurun.png

  • The Brute: He acts as Micchy's attack dog.
  • Combat Tentacles: He can summon snakes from his body to bind his opponents.
  • Dumb Muscle: A big hulking brute who's less tactically minded than Demushu.
  • Jerkass: What little characterization he gets is that of an over-confident jerk.
