Kikaider REBOOT tie-in

For general tropes, see Kikaider.

    Jiro/Kikaider 

Jiro/Kikaider

Portrayed by: Jingi Irie (live), unknown suit actor

https://static.tvtropes.org/pmwiki/pub/images/jiro_1.png
https://static.tvtropes.org/pmwiki/pub/images/kikaider_28reboot29.png

The protagonist of the 2014 film Kikaider REBOOT.


  • All Animals Are Dogs: He was basically the Kazuraba siblings' dog for the episode.
  • Amnesiac Hero: Thanks to that ridiculously convenient bolt of lightning.
  • Deus ex Machina: That Lightning Bolt of Amnesia was basically this trope setting things up for the crossover plot.
  • Duality Motif: Kikaider's red half represents evil, while it is his blue half that represents good.
  • Henshin Hero: Of course.
  • Lethal Chef: Since he can't taste, all of the food he makes for Kouta and Akira is too salty.
  • Literal-Minded: When Kouta shows his childhood photo with his puppy, he goest out and found the same puppy as he saw in the photo.
  • Noisy Robots: Most of his movements are punctuated by mechanical sounds.
  • Reset Button: Both In-Universe and plot-wise. Rebooting Kikaider made him forget his time with Kouta allowing him to move on to his own plot and to provide an excuse for him not to get entangled into Gaim's plot thus making his episode not really matter in the overall plot.

    Hakaider 

Hakaider

Portrayed by: Tsunenori Aoki (voice), unknown suit actor

Kikaider's nemesis; an android belonging to the organization DARK. His body was given to Ryoma by a colleague of his for final testing.

Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle

    Bujin Riders 

The Bujin Riders are essentially Gods of war who look like past Kamen Riders and exist in a dimension based on the Sengoku Period. Each of them is affiliated with a certain province and serves said province's general.


  • Humanoid Abomination: The Bujin do not have human forms as Kamen Riders usually do.
  • Sacrificial Lamb: Some of them are killed onscreen by Bujin Gaim to show off how strong and evil he is.
  • Swallowed Whole: All of them are completely devoured by Bujin Gaim's Pitcher Plant Monster when he defeated them.
  • War God: The Bujin Riders are perceived as this in their world.

    Kamen Rider Bujin Gaim 

Kamen Rider Bujin Gaim

Portrayed by: Rikiya Koyama (voice), Kenji Tominaga (suit)

https://static.tvtropes.org/pmwiki/pub/images/bujin_gaim_6.png
(Guitar riff) Blood Orange Arms: Ja no Michi on Stage!note 

The villain of Gaim's section in Fateful Sengoku Movie Battle. An Alternate Universe counterpart of Gaim bent on conquest.


  • Badass Baritone: What a baritone.
  • Badass Boast: Instead of going Oh, Crap! like most villains would in response to facing six Kamen Riders (including three experienced ones) by himself, he gives one of these.
    Bujin Gaim: I'll take you all on!
  • Big Bad: Of the Non-Serial Movie.
  • The Conqueror: His general characterization. Notable because in his world, he's the only Bujin to not have a general and to be acting on his own.
  • Diabolus ex Nihilo: Bujin Gaim just appeared one day wanting to take over the world, being eviler, meaner, and more powerful than the other Bujin for no explained reason.
  • The Dreaded: In-Universe within the Sengoku World. Justified, since he basically killed all the other Bujin Riders.
  • Evil Laugh: He's rather fond of these.
  • Evil Sounds Deep: Unlike the other Bujin Riders, who sound like their counterparts, Bujin Gaim has a deep booming voice.
  • Evil Twin: Looks like a darker version of Orange Arms Gaim.
  • Expy: As a movie-exclusive villainous rider who wears a darker recolor of the hero's armor, as well as being the evil twin of the main rider, he's one of Kamen Rider Ryuga. Although given the circumstances he's fought in, he can also be compared to the Fake Agito that Ryuki fought.
  • Finishing Move:
    • Naginata Musou Slicer: Bujin Gaim combines his Blood Daidaimaru and Musou Saber in Naginata modelocks the Blood Orange Lockseed into the slot, charges the Daidaimaru end with energy before he slashes the enemy with it.
  • Generic Doomsday Villain: Let's just say his final plan is not too terribly imaginative
  • Green Thumb: His One-Winged Angel form. His Dragon is also a Plant Person.
  • Hero Killer: Killed all the Bujin Riders in the film.
  • The Juggernaut: Can easily fight six Kamen Riders at once and can keep on going.
  • One-Winged Angel: Lotus Position, in which he fuses with a giant, sacred tree.
  • Outside-Context Problem: From the perspective of the other Bujin, as not only did he act on his own, but leads an army of Kaijin instead of humans, which didn't seem to otherwise exist in that world.
  • Palette Swap: The base suit is mostly the same as "our" Gaim, but his Arms is a red Blood Orange as opposed to Gaim's orange... Orange. He also has parts of his forehead crest colored blood-red, as well as a black patch on his mouthplate (which regular Gaim doesn't get until Jimber Arms).

Kamen Rider Gaim vs. Ressha Sentai ToQger: Spring Gattai Special

Moguraroidnote 

    Moguraroid 
https://static.tvtropes.org/pmwiki/pub/images/mogura_roid.png
  • Beware the Silly Ones: His dopey behavior and speech belied the fact that he had a genuine ace in the hole, an identical sibling.
  • Harbinger of Impending Doom: Played straight with his last words. And considering this special aired after its intended tie-in Kamen Rider Taisen...
  • Rule of Three: Demonstrates his ability to make his own Cracks three times - the first two unknowingly summon the same Lion Inves just to wail on him, but the third successfully summons the second Mole Kaijin he'd intended.

Narutaki

    Narutaki 
  • Blatant Lies: Claiming to be an ally of all Riders. Like his true agenda, it's still up in the air.
    • It's worth noting that there is a grain of truth to his statement, considering that he doesn't state Kamen or Armored - if you interpret him as saying he's an ally of the latter, it works much better, since he is only helpful to Kouta, as opposed to Tsukasa.
  • Unexpected Character: Which applies to both him and his new monkey hand puppet, really.

Heisei Riders vs. Showa Riders: Kamen Rider Taisen feat. Super Sentai

    Ren Aoi/Kamen Rider Fifteen 

Ren Aoi/Kamen Rider Fifteen

Portrayed by: Itsuji Itao (live), Kenji Tominaga (suit)

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

The villain of Kamen Rider Taisen. He serves the Badan Empire (the villains of Kamen Rider ZX) and uses the Heisei Rider Lockseed to copy the powers of Heisei Riders.

Tropes that apply to him in general

Tropes exclusive to him as Kamen Rider Fifteen

https://static.tvtropes.org/pmwiki/pub/images/kr_15.png
  • Brought to You by the Letter "S": Wears a crown in the shape of the kanji for "fifteen".
  • Exactly What It Says on the Tin: Named Fifteen, and can tap into the Heisei Riders's powers with the Heisei Rider Lockseed. There are fifteen Heisei Riders.
    • Even more literally, the "十五" on his helmet actually means "fifteen" in Japanese.
  • Finishing Move: With the Heisei Rider Lockseed, Fifteen can do an attack based on a Legend Rider.
    • Decade Arms:
      • Hibiki Squash: By drawing on the power of Hibiki: Fifteen summons a pair of Ongekibou Rekka and fires multiple purple fire bullets.
      • Decade Squash: Fifteen summons the Ride Booker in sword mode, and unleashes a series of slashes.
    • Fourze Arms:
      • Au Lait: Fifteen charge the Billy the Rod before he unleasing a 360 degree electricity based turn slash on the target.
    • Gaim Arms:
      • Au Lait: Fifteen charge the Daidaimaru with orange slice based-energy before unleashing a series of slashes on the target.
      • Sparking: Fifteen uses the Daidaimaru and his Yomimaru to block an attack. This finisher failed at blocking Gaim’s Ichigo Squash rider kick.
  • Power Copying: He uses the previously established Wizard and Fourze Arms, as well as Decade and even Gaim Arms!
  • Skeletons in the Coat Closet: His primary suit screams this trope.

    Showa Riders 

Takeshi Hongo/Kamen Rider #1

Portrayed by: Hiroshi Fujioka

  • Genius Bruiser: In case you forgot the one of the reasons Shocker turned him into a cyborg was his genius intellect.
  • Jack of All Stats: He is the most balance fighter among the Kamen Riders.
  • The Leader: He leads all the Kamen Riders in the final battle against the Badan.

Keisuke Jin/Kamen Rider X

Ryo Murasame/Kamen Rider ZX

Portrayed by: Sugata Shun

    Heisei Riders 

Tsukasa Kadoya/Kamen Rider Decade

Portrayed by: Masahiro Inoue

Shotaro Hidari/Kamen Rider W

Portrayed by: Renn Kiriyama

  • Bunny-Ears Lawyer: With all his selling of the "hard-boiled" image and all, he's still in business.

Takumi Inui/Kamen Rider Faiz

Portrayed by: Kento Handa

  • Survivor Guilt: It's so strange how Takumi felt guilty of Kusaka's death, given the latter is such an insufferable jerkass where he constantly bullies Takumi in their series.

Masato Kusaka/Kamen Rider Kaixa

Portrayed by: Kohei Murakami

    Badan 

Ambassador Darkness

Portrayed by: Shun Sugata

The Generalissimo of Badan

Voiced by: Tomokazu Seki

The ruler of the Badan Empire, which is actually a land of the dead. He finally appears to confront the Kamen Riders personally.


  • Ascended Extra: His only non-manga appearance was at the end of Kamen Rider ZX...which was released back in 1984!
  • Back for the Dead: He is destroyed, presumably for good, by the combined mecha of the Sentai rangers and Den-O.
  • Big Bad: In Kamen Rider Taisen.
  • Dimension Lord: It seems that he rules the land of the dead itself.
  • Feed the Mole: He's aware that Kamen Rider ZX was disguising himself as Ambassador Darkness, and ensured that when ZX struck he only destroyed a decoy. However, ZX still one-ups him with the Kamen Rider Lockseeds.
  • Skull for a Head: The head of his dinosaur form opens up to reveal a skull with three sockets.

The Great Soccer Match! The Golden Fruit Cup!

    Kohgane/Kamen Rider Mars/Kamen Rider Jam 

Kohgane/Kamen Rider Mars

Portrayed by: Kataoka Ainosuke VI (live), Yasuhiko Imai (suit), Satoshi Fujita (suit as Jam) Honoka Ando (live as Jam), Atsushi Ono (voice as Jam)

https://static.tvtropes.org/pmwiki/pub/images/kougane.png
SPOILER 
A personification of the Forbidden Fruit, created in an experiment by the Overlords and awakened in a different experiment by Ryoma. He ends up surviving the film and returns in the final TV episode, set months after the resolution of the Helheim conflict; possessing a girl as Kamen Rider Jam.

Tropes that apply to him in general

  • A God Am I: He proclaimed himself as the "God of the new generation" when he introduced himself to Kouta and Mai during the movie.
  • Ancient Evil: He predates the destruction of the Overlords' civilization, and was partially responsible for it.
  • Anthropomorphic Personification: Of the Forbidden Fruit (or rather, an artificial copy of the original Forbidden Fruit, created by a Femushinmu scientist) itself.
  • Big Bad: Of the film.
  • Came Back Wrong: Possibly. He apparently bonded with the locusts he'd been using in the movie to come back for the series, but he's not all there anymore.
  • Canon Immigrant: He's back for the epilogue of the series.
  • Classically-Trained Extra: Kohgane's actor is a renowned Kabuki performer - basically the Japanese equivalent of a classically trained Shakespearian Actor. The reason he took the part? He grew up watching Kamen Rider, and he hopes that his role as the movie's villain will cause children to recognize him when they watch Kabuki performances with their families.
  • Dead Person Impersonation: Assumed the identity of Yuya for about half of the movie.
  • Demonic Possession: Possesses the body of a girl in the epilogue. Fortunately, Kouta drives him out.
  • Early-Bird Cameo: Appears in Rider form during episode #37 of the main series before the movie's premiere.
  • Evil Sounds Deep
  • Expy: In terms of the Ryuki Riders, Kohgane as Kamen Rider Mars, is an equivalent to Kamen Rider Odin due to their gold-color schemes in their armor and both of them are the most powerful ridernote  in their respective series. It gets reinforced even further when he comes back as Kamen Rider Jam, since like Odin, he needs a puppet to function.
  • Gone Horribly Wrong: He's an attempt by the Overlords to create an artificial Golden Fruit. He became self-aware and directly contributed to the destruction of their entire civilization.
  • Hostage Situation: He gleefully explains to Micchy that if he shoots him, the girl he's possessing will die.
  • Large Ham: He's pretty much the Alan Rickman of Kamen Rider.

Tropes exclusive to him as Kamen Rider Mars

https://static.tvtropes.org/pmwiki/pub/images/mars_golden_arms.png
Golden Arms! Ōgon no Kajitsu!note  (Baroque choir with harp music)





Tropes exclusive to him as Kamen Rider Jam

https://static.tvtropes.org/pmwiki/pub/images/krj_darms.png
Darkness Arms! Ōgon no Kajitsu!note  (Sinister choir with harp music)
  • Brought to You by the Letter "S": Jam's visor is in the shape of 邪, or "Ja", which means "evil".
  • Casting a Shadow: Jam's Darkness Squash and Au Lait finishers.
  • Finishing Move: Jam can activate a finisher based on the number of times he presses the knife down.
    • Squash: Jam summons up to 15 energy apples, then slashes an energized Dark Daidaimaru Naginata Mode to send them flying so as to bombard the enemy.
    • Au Lait: Jam summons a bigger energy apple, then jabs the Dark Daidaimaru Naginata Mode into it, sending it flying at the enemy.
  • Palette Swap: Darkness Arms is a recolored version of his Mars armor. He also uses a recolored Daidaimaru.
  • Punny Name: "Jam" combines "ja" for "evil" with "jam", a thing you make out of fruit.
  • Red and Black and Evil All Over: Inverted, as the undersuit is white while Darkness Arms is black and neon pink, which carries a similar Obviously Evil effect.

    Lapis/Kamen Rider Kamuro 

Lapis/Kamen Rider Kamuronote 

Portrayed by: Taketo Tanaka (live), Satoshi Fujita (suit)

https://static.tvtropes.org/pmwiki/pub/images/lapis_6.png
A strange boy with an interest in soccer. He's actually a Femushinmu (the Overlords' original species), but a peaceful one who tried to stop his world's conflict. He takes an interest in soccer and even creates an entire alternate universe around it because he's curious as to how humans can engage in competition that doesn't end in bloodshed.

Tropes that apply to him in general

  • Ambiguously Human: Well, we know he's not human, but otherwise we don't know what the deal with him is. Maybe he's an Overlord, maybe he's a ghost.
  • Dead All Along: Still ambiguous, but the final shot in the movie shows his brace buried within the Helheim Forest, as if it was there for a long time.
  • Creepy Child: There's something off about him, and he looks younger than everyone else.
  • Early-Bird Cameo: Appears in person during episode #37 of the main series before the movie's premiere.
  • Foil: To Gaim, like the main series' Overlords are counterparts to Baron, Ryugen, and Zangetsu.

Kamen Rider × Kamen Rider Drive And Gaim Movie War Full Throttle

    Megahex 

Planet Megahex/ZZZ Megahex

Portrayed by: Shin-ichirō Miki (voice)

https://static.tvtropes.org/pmwiki/pub/images/megahex.png
ZZZ Megahex 

A mechanical entity of alien origin. The Megahex collective was one race's answer to the threat posed by the Helheim forest. Like the Helheim forest, the Megahex collective seeks to drive forward the evolution of other species, and Megahex wishes to accomplish this by assimilating all lifeforms into itself.


  • A God Am I: While Megahex itself never claims this, Mecha Ryoma Sengoku is overjoyed to be part of the collective, viewing it as the achievement of his ambition to become a being that surpasses humanity.
  • Alien Invasion: It invades Kouta's planet, then Earth.
  • Aliens Speaking English: Megahex initially speaks its own language when it first appears on Kouta's planet. It learns how to speak Japanese by reading his mind. Megahex briefly slips back into its native language when attempting to process the emotion of anger during its Villainous Breakdown.
  • The Assimilator: Megahex's goal is to assimilate all life into its collective as so to bring about its ideal vision of evolution.
  • Back from the Dead: It revives Ryoma Sengoku and Kaito Kumon as cyborgs to do its bidding.
  • Big Bad: Of the Gaim portion and the Movie War portion of Movie War Full Throttle.
  • Blade Below the Shoulder: Its primary means of attacking.
  • Combat Tentacles: See Green Thumb below.
    • Even before that, Megahex spawned wires during its first fight with Gaim in order to hold Gaim in place and read his memories.
  • Eldritch Abomination: Megahex's true form is a planet and the result of an entire species merging into one mechanical Hive Mind that deploys drones to assimilate entire worlds into its collective.
  • Expy: In the context of Gaim's story, Megahex is basically a robot version of DJ Sagara, being the avatar of a massive alien collective that desires to accelerate evolution in other species.
    • Megahex is very similar to Meta-Cooler. Planet Megahex is essentially the Big Gete Star for the same reasons.
  • Eye Scream: When its dragon form is chasing the Tridoron with Drive and Gaim in it, they use the power of the Shift Fruits Car to make it splash orange juice in Megahex's eyes, blinding it.
  • Fighting a Shadow: The Megahexs are simply avatars controlled remotely from the core of Planet Megahex. Unless the core is destroyed, destroying the individual avatars accomplishes nothing. This is how it beats Kouta: he managed to destroy the avatar only to be ambushed by another.
  • Fusion Dance:
    • It merges with the Roidmude body of Cyberoid ZZZ, becoming ZZZ Megahex.
    • The various ZZZ Megahex avatars can combine together into a giant, mechanical dragon reminiscent of a Giant Roidmude.
  • Genius Loci: The entire collective is controlled remotely from the core of Planet Megahex.
  • Green Thumb: Sort of. Upon assimilating the Kiwami Lockseed, Megahex demonstrates the ability to spawn and manipulate robotic Helheim vines.
  • Golden Super Mode: Two of them.
    • Once it assimilates the Kiwami Lockseed, Megahex's chest plate glows golden.
    • ZZZ Megahex has golden accents in many places where blue used to be on its original form.
  • Healing Factor: ZZZ Megahex is able to regenerate from the damage that Drive and Gaim do to it. They have to use the power of Drive Arms and Type Fruits to damage it faster than it can repair from.
  • Hero Killer: He kills Kouta near the beginning of the movie. Kouta doesn't stay dead thanks to the precautions he took.
  • Hive Mind: The Megahex are one of these formed from an entire species using Brain Uploading to survive Helhiem, with their core consciousness stored in the core of Planet Megahex. The individual drones consistently refer to themselves as 'we', with one only slipping into singular during a Villainous Breakdown while trying to comprehend anger.
  • Humongous Mecha: As it's chasing Drive and Gaim, its various ZZZ Megahex avatars fuse into a massive dragon reminiscent of a Bat-type Giant Roidmude.
  • Keystone Army: Planet Megahex must be destroyed to shut down every Mecha Inves and Mecha Roidmude in its control. Mecha Kaito also deactivates along with them.
  • Me's a Crowd: There are hundreds of avatars for the Megahex collective to operate remotely.
  • Mook Maker: Megahex creates androids based on the Kurokage Troopers called Mecha Kurokage to serve it. It also spawns a group of numberless Mecha Roidmudes to serve as front guard of its stronghold, with Mecha Inves inside. After absorbing Cyberoid ZZZ, it unleashes an army of Mecha Inves and Mecha Roidmudes to fight the Riders.
  • One-Winged Angel: Its above mentioned Golden Super Modes might count, but more in line with this trope would be its dragon form.
  • Outside-Context Problem:
    • Megahex is an out-of-context villain who seemingly appears just to kidnap Mai and wreck Kouta's planet. However, it gets subverted, as Mecha Ryoma later explains how Megahex ties into the lore of Gaim (Megahex was how one planet addressed the invasion of the Helheim Forest, so Megahex is essentially the "Man of the Beginning" for its native species).
    • Megahex is absolutely an Outside-Context Problem from the perspective of Drive. It literally shows up out of nowhere, merges with the burnt-out Roidmude body of Cyberoid ZZZ, says some threatening words, and flies off. It has no other connection to any of the backstory and lore of Drive.
  • Physical God: It was able to match Kouta as the Man of the Beginning, though Kouta won...only to be ambushed by a second avatar from behind.
  • Soul Jar: The core of Planet Megahex needs to be destroyed to finally end the Megahex collective. Additionally, the Roidmude core of Cyberoid ZZZ merges with this after ZZZ Megahex is destroyed by Drive and Gaim, allowing all subsequent avatars to assume the form of ZZZ Megahex.
  • Third-Person Person: Megahex tends to refer to itself in the third person.
  • Villainous Breakdown: Megahex seriously loses it when Takatora and Mitsuzane foil its plans too often and take back the Kiwami Lockseed.
  • Well-Intentioned Extremist: Megahex genuinely believes itself to be the best way for all species to evolve, and fails to understand why the heroes would tolerate humanity's own imperfections and differences.
  • What Happened to the Mouse?: It's never explained how Megahex was able to create Mecha Roidmudes even before it combined with Cyberoid ZZZ.

Kamen Rider Gaim Gaiden

    Touka Akatsuki/Kamen Rider Idunn 

Touka Akatsuki/Kamen Rider Idunn

Portrayed by: Sayuri Iwata (live), Ai Uchida (teen), Satoshi Fujita (suit)

https://static.tvtropes.org/pmwiki/pub/images/touka_akatsuki.png
An orphan who used to work for the Kureshima family as a maid. In her youth, she befriended Takatora and made him an apple pie. She was experimented on when she was younger, giving her the ability to control Cracks and Helheim flora, and this left her with a fierce desire for revenge. She was the one who murdered Takatora and Micchy's father, and intends to kill them too.

Tropes that apply to her in general

  • Action Girl: Even without transforming, she briefly demonstrated considerable martial arts skills when she ambushed Takatora.
  • Childhood Friends: With Takatora Kureshima, who she was also a personal maidservant to, and they were very close, at that. The truth of her origins sours things.
  • Death Seeker: When Takatora defeated her, she seemed to be egging him on to kill her, saying that she would return and try to kill him again if he spares her. He can't bring himself to do it, but Ryoma, on the other hand…
  • Did They or Didn't They?: Taking the Kissing Discretion Shot mentioned below into consideration, Takatora's actor mentioned in an interview for the special that there would be some "very wet" bed scenes. There are no such scenes in the final product, but the fact that Takatora and Touka have a tender moment at her house implied to lead to at least a kiss makes one wonder…
  • The Dog Bites Back: Years of being painfully experimented on by Amagi Kureshima were repaid with death.
  • Evil Cannot Comprehend Good: Doesn't understand that Takatora spared her because of his bond with her. Ryoma on the other hand is more willing to do so. However, it's partially averted in that she recognizes that Takatora was a good person despite everything else.
  • Good Counterpart: To Ryoma. Both come from the same facility, which explains how both are screwed up. But while the experimentation removed anything human in Ryoma, Touka's revenge, however extreme and misguided, is aimed at paying Yggdrasil back for their inhumanity, and she is still genuinely fond of Takatora, cherishing their childhood together.
  • Green Thumb: She can control Helheim flora much like an Overlord.
  • Kissing Discretion Shot: There's a scene where she and Takatora look like they're about to kiss at her house, but the camera pans down to a fence post blocking the view. Said fence post is tangled in Helheim vines.
  • Lethal Chef: A downplayed example. It's commented by Takatora that her apple pies are terribly made, though he still eats them out of affection for her and appreciation for their friendship.
  • Roaring Rampage of Revenge: She wants vengeance against the Yggdrasill Corporation and the Kureshima family.
  • Sadist: The expression on her face when recounting her murder of Amagi Kureshima shows that she thoroughly enjoyed getting her revenge. That she chooses to target everyone connected to him, not just the man himself, calls into question just how much of her motives are rooted in revenge.
  • Ship Tease: With Takatora.
  • Tragic Monster: While she does want to bring Yggdrasill and the Kureshimas down, she does genuinely cherish her time with Takatora and in her dying moments, thinks back to said moments and laments that someone like Takatora had to be of the Kureshima family and Yggdrasill.
  • Unwitting Pawn: In a similar way to Tyrant mentioned below, Touka ended up serving as a test subject for one of Ryoma's experimental prototype lockseeds. In her case, her successful use of the Forbidden Ringo Lockseed's powers helped him prove that the Golden Fruit does indeed exist.

Tropes exclusive to her as Kamen Rider Idunn

https://static.tvtropes.org/pmwiki/pub/images/kamenrideridunn.png
Come On! Ringo Arms! Desire Forbidden Fruits!
  • Combat Tentacles: Subverted. She's shown to be able to manipulate Helheim vines just like the Overlords, but she never uses them in battle.
  • Expy: Her Ringo Arms is basically a copy of Mars' Golden Arms, using the same fruit and armaments.
    • Its design is slightly more reminiscent of Kamuro's Silver Arms, while Kaito's version of Ringo Arms resembles Mars more.
    • In-Universe, the Lockseed was Ryoma’s attempt to recreate the Golden Ringo Lockseed.
  • Finishing Move: Idunn can activate a finisher based on the nine r of times she press the knife down.
    • Squash: Idunn charges and unleashes a powerful slash with the Sword Bringer.
  • Meaningful Name: Iðunn was a Norse goddess who held the fruit that the gods used to stay young.
    • Her Rider name can also be read as Eden, alluding to another forbidden fruit myth.
  • Thinking Up Portals: Her lockseed gives her the power to open and manipulate Cracks to and from Helheim, which she uses to make quick escapes and get the drop on her targets.

    Amagi Kureshima 

Amagi Kureshima

Portrayed by: Minori Terada

https://static.tvtropes.org/pmwiki/pub/images/amagi_kureshima.png
The father of Mitsuzane and Takatora who is the founder of Yggdrasil Corporation. Not much is known about his life, except that he performed experiments on young children, to make them fit to become future Yggdrasill workers.
  • Corrupt Corporate Executive: He was the man behind Yggdrasill until his death. This was also the second time that his actor played a role who was also a CCE five series before Gaim.
  • Expy: Literally of the Museum CEO Ryubee Sonozaki, for added bonus, he is played by the same actor.
  • Missing Mom: In the series, he is implied to be working overseas. In Gaim Gaiden: Zangetsu, Touka murders him.
  • Would Hurt a Child: He used children as his guinea pigs to mold them into workers for Yggdrasill. It bites him in the ass, however.

    Shapool 

Shapool

Portrayed by: Yutaka Kobayashi

https://static.tvtropes.org/pmwiki/pub/images/shapool.png
An heir to a foreign organization, Shapool is physically identical to Kaito. He attempts to imitate Kaito after seeing him in a Beat Riders Hotline video, and even drugs Kaito to steal his clothes, but fails to pull off the imitation due to his different personality and inability to use Kaito's Sengoku Driver. His butler, Alfred, attempts to murder him, leaving it up to Kaito to protect Shapool.
  • Beware the Silly Ones: He pretty much ran up to Kaito and incapacitated him with some sort of pepper spray to the face.
  • Identical Stranger: To Kaito.
  • Imposter Forgot One Detail: More like every detail. He fails at imitating Kaito because his personality is pretty much an exact opposite.
  • Instant Expert: Though he moves like an amateur early on, he learns the dance style and routine of Team Baron with surprising ease (or at least manages to improvise something similar that somewhat resembles the rest of the team's moves and looks fairly competent).
  • Keet: This is part of the reason no-one buys his Prince and Pauper act with Kaito.
  • Manchild: He calls Alfred a meanie for being strict, and his behaviour while pretending to be Kaito just screams "excited toddler".
  • Prince and Pauper: Attempted by force.
  • Rebellious Heir: While his natural behavior is rebellious in terms of being formal, he's also been forced into this situation. See below.
  • Supreme Chef: He baked a delicious cake at Charmant, which Mai and Hideyasu savour. This baking skill is one thing he and Kaito have in common besides appearance.
  • You Have Outlived Your Usefulness: It turns out, he's no longer actually the heir. He was merely adopted to be one, until his father had a natural-born son. And he's aware that he's been considered expendable. He just didn't realize that it's to the point of wanting him killed.
  • Offing the Offspring: Unbeknownst to him, he's been marked for death by his own father, who no longer needs an adopted son now that he has a natural-born heir.

    Alfred/Kamen Rider Tyrant 

Alfred/Kamen Rider Tyrant

Portrayed by: Gamon Kaai (live), Yugo Fuiji (suit)

Shapool's butler, Alfred is a strict and ruthless man who plans to murder his charge and pretend he died in an accident. He receives a Genesis Driver and the Dragonfruit Energy Lockseed from Ryoma, letting him become Kamen Rider Tyrant, but the Lockseed is a flawed prototype which ultimately transforms Alfred into an Overlord Inves. He is finally defeated by Kaito using Ringo Arms.

Tropes that apply to him in general

  • Badass in a Nice Suit: Makes sense given his job.
  • Battle Butler: Albeit more treacherous than the usual kind.
  • Call-Forward: His transformation into an Overlord Inves hints at Kaito's own transformation into Lord Baron.
  • Four Eyes, Zero Soul: He's fully willing to kill Shapool in accordance with his master's wishes.
  • Knight of Cerebus: While Gaim is already a very grim and serious show, Alfred's scenes in the Baron special are the ones that take a sharp turn from what began as a mostly lighthearted, comedic story (albeit, with mentions of grim subjects like parental abuse and suicide) into more serious matters like treason and attempted murder.
  • Let's Get Dangerous!: When Kaito resists being taken by his men after they mistake him for Shapool, Alfred decides that they're not playing nice anymore and stops trying to hide his true nature, starting with having Kaito incapacitated by tasers.
  • Make It Look Like an Accident: This is what he was going to do to Shapool under the orders of Shapool's father.
  • Shout-Out: He's a butler named Alfred.
  • The Starscream: Despite the lack of spoiler tags to his treachery, the plan to murder Shapool actually originally comes from his father. What actually makes him apply for this trope is that after talking to Ryoma and given the Driver and Lockseed, he decides to kill Shapool's father as well and take over the foundation.
  • Unwitting Pawn: It's really apparent that Ryoma gave him the Dragon Fruits Energy Lockseed simply to use him as a guinea pig.

Tropes exclusive to him as Kamen Rider Tyrant

    Kugai Kudo/Kamen Rider Saver 

Kugai Kudo/Kamen Rider Saver

Portrayed by: Jun Toba (live), Yugo Fujii (suit)

https://static.tvtropes.org/pmwiki/pub/images/kugai_kudo.png
The previous head of Yggdrasill's scientific division before Ryoma, and the apparent leader of a cult called the Black Bodhi Tree. He was the subject of the first Lockseed test, which went horribly wrong and transformed him into an incorporeal being, which he insists was actually Ascended to a Higher Plane of Existence. He orchestrates terrorist attacks on Yggdrasil and Ryoma in particular using Brainwashed and Crazy innocents to test Ryoma, believing that with Ryoma's assistance, he can become a god and save the world.

Tropes that apply to him in general

  • Ascended to a Higher Plane of Existence: Because of the botched test of the first Lockseed, he apparently became a higher being.
  • Big Bad: Of both Duke Gaiden and the Tie-In Novel for the series. He's also the Greater-Scope Villain for Knuckle Gaiden.
  • Cult: He leads one called the Black Bodhi Tree. Specifically, he brainwashes them with copies of his Zakuro Lockseed and turns them into suicide bombers.
  • Far-East Asian Terrorists: He uses brainwashed innocent people as suicide bombers for his operations against Yggdrasil.
  • Godhood Seeker: Wants this, but he needs Ryoma's help.
  • The Man Behind the Man: Is likely one to Shura and his Neo Baron gang.
  • Not Quite Dead: Thrice. First after the experiment that went wrong, and then Takatora thinks he's dealt with him some way into the Gaiden. Ryoma knows better and presumably finishes him off for good. Then the novel has him return and become a Final-Exam Boss, only to die again.
  • Power of the Void: After returning in the novel, Kugai gains various void-related powers such as imprisoning targets. Ryoma Sengoku suggests the possibility that this is connected to the A.R. Worlds somehow, with his Saver Arrow being pulled from a world that had already created the Sonic Arrow.
  • Saving the World: He claims he wants to do this, presumably from Helheim.
  • Sequel Hook: The very end of Duke Gaiden has him giving Shura a Banana Lockseed. In a weird twist of the trope, the sequel comes right away.
  • Teleporters and Transporters: He has the ability to teleport.
  • Your Princess Is in Another Castle!: It seems like Takatora's killed him at one point, but there are still ten minutes or so of the Gaiden left.

Tropes exclusive to him as Kamen Rider Saver

https://static.tvtropes.org/pmwiki/pub/images/armored_rider_saver.png
Ha! Blood Zakuro Arms! Kuruizaki Sacrifice!
  • All Your Powers Combined: By the novel's climax, Saver obtains the powers of Bujin Gaim, Mars/Jam, and Maja, receiving not only their Lockseeds but also any extra forms associated with them, notably Bujin Gaim's Lotus Position. Of note is that all four of these Riders were movie or stageshow villains at some point.
  • Alternate Universe: Ryoma Sengoku strongly implies Saver's armaments were stolen from the A.R. Worlds and converted to work as a singular arsenal.
  • Attack of the 50-Foot Whatever: Mutates into the Gaikotsu Kyoryu, a monster form previously used by the Generalissimo of Badan in the novel.
  • Dark Reprise: His standby loop, while never appearing in the film, is a regal-sounding remix of Baron's and Knuckle's.
  • Dual Wielding: He uses both the Saver Arrow and Bujin Gaim's Daidaimaru.
  • Evil Counterpart: To a degree, to Kouta. Both wanted to save the world and became more than human, and both used an Orange Lockseed alongside another Lockseed at some point.
  • Call-Forward: Much like Tyrant's use of the Dragonfruits Energy Lockseed that had previously debuted in a crossover movie with Gaim's immediate successor, Saver's use of the Blood Orange Lockseed chronologically occurs before Bujin Gaim's reign of terror in the crossover movie with Gaim's immediate predecessor.
    • Aside from that, his use of the Genesis Core in place of an indicator faceplate to harness and combine the power of two Lockseeds at once chronologically predates Kouta's first use of the Jimber Arms forms, and uses nearly identical mechanics.
  • Fashionable Asymmetry: His armor is notably uneven due to incorporating parts from two different armors, presumably.
  • Final-Exam Boss: The novel has Saver throw all the powers of every movie and stageshow villain at the surviving Riders, sans those of Tyrant and Duke Dragon Fruits Energy Arms.
  • Foreshadowing:
    • His custom Sonic Arrow is called the Saver Arrow, which hints at the fact that later novels would demonstrate the Sonic Arrow adapting to other users; namely, Ryugen gains a gilded dragon head, while Bravo has the upper half elongated to make it more like the Musou Saber. Ironically, the former case is part of the upgrade that finally kills him for good in the main novel.
  • Karmic Death: After collecting all the movie villain Lockseeds and using them to great effect against the surviving Riders in the novel, Kugai is finally stopped after Ryugen snatches the Dragon Fruits Lockseed from the illusory Duke Saver set on him and uses it against him.
  • Meaningful Name: Saver can also be romanized as Savior, both fit Kugai's vision of saving the world.
  • Nested Mouths: As the Gaikotsu Kyoryu in the novel, Kugai's T-Rex skull can split open to reveal another skull, this one being of a three-eyed human.
  • Obviously Evil: Despite his claims of being a saviour, there's something to be said about the fact that he uses the Blood Orange Lockseed, which has a transformation call roughly translating to, "Path of evilnote , on stage!"
  • Red and Black and Evil All Over: His armor is red and black primarily.

    Shura/Kamen Rider Black Baron 

Shura/Kamen Rider Black Baron

Portrayed by: Ryusuke Nakamura (live), Eitoku (suit)

https://static.tvtropes.org/pmwiki/pub/images/shura_5.png
A former member of what would become Team Baron, Shura was kicked out by Kaito for cowardice after trying to attack him from behind with a pipe. He resurfaces after the end of the series as the leader of Neo Baron, a gang claiming to follow Kaito's ideals, but which practices them through brutal fights. In truth, Neo Baron has connections to the Black Bodhi Tree, meaning Shura and his goons have access to Sengoku Drivers and Lockseeds, and Shura's true plan is to reconstruct the Scalar System in a new form as the Saver System and use it to wipe out the weak, or rather everyone not affiliated with Neo Baron.

Tropes that apply to him in general:

  • Arch-Enemy: Zack immediately sees him as such once he got heads-up of his illegal activities and for tarnishing Kaito's legacy.
  • Cult: Neo Baron is basically one around Shura's twisted interpretation of Kaito's ideals. He also has connections to an actual cult, the Black Bodhi Tree.
  • Dirty Coward: Aforementioned incident with attacking Kaito from behind, and he sets a couple of goons on Zack when he realises he's losing. Zack explicitly points out that this, rather than being weak, is why Shura was kicked out of Team Baron.
  • Evil Counterpart: He's basically Kaito if Kaito was a true Social Darwinist, with none of Kaito's honor and moral compass.
  • From Nobody to Nightmare: From a Dirty Coward in a breakdancing team to a brutal gang leader of a fight club with desires to exterminate potentially hundreds of thousands of people.
  • Hate Sink: Shura has little to no redeeming qualities whatsoever, solely existing for warping Kaito's Darwinistic worldview, and gleefully plays dirty when things go south for him. Shura does not possess the one quality what made Kaito so respected by his peers: his sense of honor. Metaphorically, his transformation into Black Baron serves as a mockery to Kaito's legacy.
  • Hijacked by Ganon: There are a couple of hints that Kugai might be influencing Shura. Aside from explicitly naming the hypothetical recreated Scalar System as the Saver System, the credits of the previous Gaiden show that Shura got his Lockseed from Kugai, and he's seen handing out a Zakuro Lockseed to the winner of a fight as proof of Neo Baron membership. And he's explicitly stated to have connections to the Black Bodhi Tree.
  • Misaimed Fandom: In-Universe, big time. He idolizes Kaito and the idea of strength, and carries out a standard Social Darwinist routine as a result. As Zack points out, Shura doesn't understand Kaito at all, because Kaito despised the fact that the world itself was a Social Darwinist and sought power to change that.
  • Social Darwinist: He believes in strength above all. And he's planning to wipe out the weak.

Tropes exclusive to him as Kamen Rider Black Baron

https://static.tvtropes.org/pmwiki/pub/images/kr_black_baron.png
Come On! Banana Arms! Knight of Spe~ar!
  • Black Knight: As his name suggest, this is essentially Kamen Rider Baron suit only in black color. Making him a stark contrast to the real Kamen Rider Baron.
  • Evil Knockoff: As the name makes clear, it's the Baron suit with black instead of red, fitting symbolism for how Shura is perverting Kaito's ideals.
  • Fashionable Asymmetry: As with Kaito's Baron armor, one shoulder pad is larger than the other.
  • Finishing Move: Black Baron can activate his finishers based the number of times he press the knife down.
    • Au Lait: Black Baron charges the tip of the Bana Spear and charges towards the enemy.
    • Sparking: Black Baron stabs the Bana Spear onto the ground, creating multiple banana-shaped projections which hit an opponent several times from below. Unlike normal ones, Black Baron's variant produces purple energy bananas instead.
  • Meaningful Name: Aside from referencing the Paint It Black treatment, Black Baron is a reference to a fighter ace, like how Kaito's red-colored Baron suit was a reference to the Red Baron.
  • Paint It Black: Shura's version of the suit has a black undersuit instead of red.
  • Stealth Pun: Just like how Kaito's use of the Banana Lockseed could be used to set up puns about him playing "second banana" to Gaim, Shura could be said to be a "rotten banana".
  • Transformation Trinket: His Banana Lockseed, which is notable in that while it functions more or less identically to Kaito's, it has no Lockseed number (i.e. the space that normally says L.S.-08 is completely blank).

    Masako Suzuka/Kamen Rider Sylphi 

Masako Suzuka/Kamen Rider Sylphi

Portrayed by: Tomomi Jiena Sumi (Live), Momoka Takasaki (suit)

Jounochi’s assistant after he becomes an acclaimed patisser, she secretly wants to use his recipes to distribute Helheim Fruits across the world.

  • Ambiguously Human: Has some control over the Helheim fruits and notably doesn’t get the usual Defeat Equals Explosion.
  • Bad Powers, Bad People: Her lockseed is the Helheim Lockseed, making it the first instance of a Helheim fruit not morphing into a new fruit type upon becoming a Lockseed.
  • Bitch in Sheep's Clothing: Initially appears to be an innocent assistant, but is actually a cunning mastermind.
  • Blade on a Stick: Armed with a spear topped with the outer skin of a Helheim Fruit.
  • Curb-Stomp Battle: Kamen Rider Sylphi vs. Kamen Rider Zangetsu, otherwise known as the newbie villain up against the show’s World's Strongest Man who is also using his Super Mode. At no point in the fight does Takatora give the impression of actually trying.
  • Dying Curse: As she passes, she says that Takatora's fighting will never end, a fact he accepts.
  • Finishing Move: Sylphi can activate a finisher on the number of times she press the knife down.
    • Sparking: Sylphi jumps and charges with her weapon, forming a purple energy on the tip to stab the opponent with.
  • Generic Doomsday Villain: No motivation is given for her plot to turn half the world into Inves.
  • Walking Spoiler: Just look at how much of this folder is spoilered.
