Characters from Kamen Rider Geats × Kamen Rider Revice: Movie Battle Royale
Koshiro Igarashi
Portrayed by: Kiku
The newest addition to the Igarashi family.
- Family Theme Naming: His name is spelled with the character for "four" (四/shi). He's the fourth child of the family.
- Goo-Goo-Godlike: Like his siblings, he can tap into Giff's power, and he does so instinctually to defend himself while still a baby.
- Practically Different Generations: He's at least 20 years younger than his siblings.
Koshiro's Demon
Portrayed by: Masanori Hasegawa (voice)
Koshiro's inner demon.
- Bratty Half-Pint: Belligerent, rambunctious, and loud.
- No Name Given: He's only known as "Baby Demon".
- Vocal Dissonance: Has the voice of a grown man despite having the appearance of a baby.
Colus (spoilers)
Colus/Game Master (I)
Portrayed by: Tetsuhiro Ikeda
The first Game Master
A former Game Master of the Desire Grand Prix who takes over the organization, renaming it the "Desire Royale".
- Big Bad: He's the one behind the Desire Royale and thus the main villain of Battle Royale.
- Dangerous Deserter: Left the DGP in the past, only to return to take it over for himself.
- Malevolent Masked Man: Sports his own red variants of the Game Master mask and hood.
- Meaningful Name: His name is derived from the Japanese phrase 凝らす (korasu), "to concentrate", which can involve narrowing one's eyes.
- Mirror Character: To Girori.
- Sharp-Dressed Man: Is clad in a dark gray suit beneath his mantle, complete with top hat.
- Transformation Is a Free Action: Averted as it often is in Kamen Rider Geats, but it's notably the first time an antagonist has been thwarted from transforming.
- The Usurper: Seizes control of the Desire Grand Prix to convert it into the Desire Royale.
- War for Fun and Profit: Bored of the typical Jyamoto thwarting of the DGP, he plans to use a Negative Space Wedgie and Kamen Rider Seeker's abilities to open the Earth to alien invasion, ensuring an endless stream of exotic and deadly extraterrestrial threats to keep himself and his audience entertained.
Baridero and Izangi
Baridero portrayed by: Ryō Horikawa (voice)
Izangi portrayed by: Hiroshi Kamiya (voice)
- Bare-Fisted Monk: Izangi relies on his fists.
- Carry a Big Stick: Baridero wields a quarterstaff.
- Co-Dragons: They serve as Colus's right-hand men.
- Disc-One Final Boss: Defeated at the end of the very first act, at which point the rest of the antagonists step forward.
- Playing with Fire: Both of them make liberal use of fire in their attacks.
- Revenge by Proxy: As Giff is dead by the time the movie begins, they settle on taking revenge for their world on Giff's kin, the Igarashi family.
- Sole Survivor: Of an extraterrestrial civilization destroyed by Giff many years ago.
- We Hardly Knew Ye: They don't even make it past the first act before they're destroyed by Revi and Vice.
Kaima Todoroki/Kamen Rider Seeker
Portrayed by: Yusuke Onuki (live), Takuma Komori (suit)
- The only one to become the Desashin will be me!
A retired boxer and an assassin in Colus's employ who is the undefeated champion of the Desire Royale. Using the Powered Builder Buckle and Gigant Container, he transforms into the deer/construction-themed Kamen Rider Seeker.
Tropes applying to him in general
The Undefeated Rider
- Always Someone Better: He's shown to feel this way toward his more-successful older siblings, which drives him to earn his father's approval.
- Animal Motifs: Deer — specifically moose; he's the hired muscle for Colus and given his previous profession quite the powerhouse, though contrary to the usual portrayal of moose in fiction, he's far from unintelligent.
- The Brute: He serves as Colus's personal hitman in the Desire Royale. Appropriately enough, he used to be a professional boxer.
- Contrasting Sequel Antagonist: Both Kamen Rider Odin and Kaima are the gold/bright yellow-colored 13th Riders of their series' Battle Royales, and also the enforcers/proxies of their respective Game Masters. Odin was a mindless puppet under Shiro Kanzaki's thrall, while Kaima works for Colus out of his own free will.
- The Dragon: To both Colus, as the champion of his game, and his father, who uses him as his representative in the Desire Royale.
- Dragon Their Feet: Colus gets taken out by Girori, leaving Kaima as the Riders' final opponent.
- Graceful Loser: Despite losing his chance to wing his father's approval, he's fine with losing to Geats and Revice, and even accepts Ikki's advice of obtaining a desire of his own, separate from what his corrupt father wants for him.
- Mirror Character: Just like how Ace is the undefeated champion of the Desire Grand Prix, Kaima is the reigning champion of the Desire Royale. As Seeker, Kaima relies on brute force and his Terrain Sculpting abilities to reshape the arena in ways advantageous to him, in contrast to Ace as Geats, who uses his wits to leverage the existing environment in his favor.
- Screw the Rules, I Have Connections!: He was once charged for assault, only getting off thanks to his politician father intervening. Then again, he was only accused of committing assault, so it is unclear if it is to be believed or not.
- Spoiled Brat: His being the youngest son of a prominent political family gives him the notion that he can get away with anything, even committing crimes; his wish for the Desire Royale is a world where his father becomes Prime Minister so he can do whatever he wants. Ultimately subverted, as all he wants is to please his father like how his better siblings did, but this doesn't change how he's essentially going to destroy the world just for that approval.
- "Well Done, Son" Guy: What he ultimately is. Because his father views him as inferior to his successful siblings due to his past history and assault charge in boxing, Kaima is desperate to make his father proud of him, even willingly accepting the fact that he is nothing but a tool for his greater ambitions. Once he's finally defeated by Geats, Revi, and Vice, Ace and Ikki help release Kaima from his father's grip and advise him to follow his heart, something he takes to heart before he disappears.
Tropes exclusive to him as Kamen Rider Seeker
Would you like a custom selection?
- Ace Custom: Anyone can use the Powered Builder Buckle and the Gigant weapons, and all of the Armed Weapon Raise Buckles fit into its slot. However, it's suggested what makes Seeker unique is his usage of the Gigant Container in the Desire Driver for his lower half as it is conspicuously absent when Geats takes the Powered Builder Buckle and Gigant Container for himself in the series proper. In addition, when he uses the Powered Builder Buckle, his right shoulder armor is different.
- Disc-One Nuke: The Powered Builder Buckle proves to be an incredibly versatile and powerful upgrade for Ace, carrying him and his fellow Riders through most of the Divergence arc with its ability to create structures and overwhelm enemies with destructive weaponry.
- Final Boss: In-Universe. After Girori takes back the Vision Driver, he changes the final round from thwarting an alien invasion to finding and defeating Seeker in “a deer hunt”.
- Finishing Move:
- Almighty Form:
- Gigant Finisher: As giant construction beams swirl around him, Seeker charges the Gigant Blaster and fires a sphere of purple energy at the target. He then swings the Gigant Sword, launching a crescent wave and following up with another shot from the Gigant Blaster.
- Almighty Form:
- Limit Break: Seeker's holster pushes the Powered Builder system to its limits, as indicated by the Desire Driver saying "WARNING" when inserted and sounding alarms whenever transforming or changing weapons. Quite tellingly, this is absent with the other buckles up to and including Boost.
- Meaningful Name: His Rider name pertains to his job as Colus's hitman, which requires him to seek out his targets. It's also a play on shika, the Japanese word for deer.
- Multi-Armed and Dangerous: The Powered Builder armor has two manipulator arms.
- Red Eyes, Take Warning: His visor with the Powered Builder upper body is crimson red, and he's one of the main antagonists.
- Terrain Sculpting: Seeker can generate and manipulate buildings at will using the Powered Builder Buckle, with most of the final battle against him taking place on top of an ever-growing tower that he constructs on the fly.
- Weapon-Based Characterization: Seeker primarily wields heavy weaponry, befitting Colus's Brute. The three Gigant Buckles grant him three such weapons:
Eiichi Todoroki
Portrayed by: Hajime Yamazaki
Kaima's father.
- Abusive Parents: He views Kaima purely as a pawn to further his own ambitions.
- Corrupt Politician: He used his status to bail out his son for assault.
- I Have No Son!: Disowns Kaima due to his proving lackluster in contrast to his more successful siblings.
- The Man Behind the Man: Sort of. He plays a major role in financing the Desire Royale, but Colus is still the one running things.
Keiwa's Demon
Portrayed by: Ryuga Sato
Keiwa's inner demon.
- Chekhov's Gunman: He is introduced in a brief scene in Geats x Revice, and plays a major role in the latter part of the main series as the implied influence behind Keiwa obtaining the Bujin Sword Buckle.
- Dissonant Serenity: The only thing he tells Kagero is that he is just an ordinary person desiring world peace in a gentle tone, yet his sheer strength terrifies Kagero. Keiwa later takes up his inner demon's eerie calm while wielding the Bujin Sword Buckle and absolutely brutalizing Michinaga in the series' Genesis arc.
- Foreshadowing: While Keiwa's Inner Demon is relatively calm and still sincerely wishes for world peace, Kagero being unnerved by his strength implies that Keiwa is repressing something so deeply that it's made his inner demon that powerful, since inner demons gain their strength from the personal flaws and regrets that their hosts won't own up to. By the time Keiwa's sister Sara dies in Geats proper, it becomes clearer that Keiwa has been stewing in his own powerlessness and desperation for quite a while, even as he's sincerely tried to work toward world peace as a Kamen Rider, and his self-perceived failures as a hero plus his desperate need to be one for his sister's sake is the most likely signifier of what his inner demon represents.
- Horrifying the Horror: Dishes this out to Kagero simply by existing, as the latter notes he appears to be obscenely powerful for someone like Keiwa, to the point that it freaks Kagero out.
- No Name Given: He is only known as Keiwa's Inner Demon.
Shinji Kido/Kamen Rider Ryuki
Portrayed by: Takamasa Suga (live)
A former reporter from ORE Journal who transforms into Kamen Rider Ryuki. His wish is to end the fighting between the Kamen Riders.
Ren Akiyama/Kamen Rider Knight
Portrayed by: Satoshi Matsuda (live)
A lone biker who transforms into Kamen Rider Knight. His wish is for the power to destroy everything.
Takeshi Asakura/Kamen Rider Ouja
Portrayed by: Takashi Hagino (live), Jiro Okamoto (suit)
A wanted criminal who transforms into Kamen Rider Ouja. His wish is to be able to fight until his dying breath.
Dark Shinji/Kamen Rider Ryuga
Portrayed by: Takamasa Suga (live)
The Mirror World self of Shinji Kido who transforms into Kamen Rider Ryuga. His wish is for the destruction of the real world.
Characters from Desire Grand Prix Bonus Stage
Sarami
Portrayed by: Nene Shida
A navigator of the DGP who bears a startling resemblance to Keiwa's sister Sara.
- Meaningful Name: Her name is a portmanteau of "Sara" and mi (見), the Japanese word for "looking".
- Punny Name: It's also a play on Tsumuri's name.
Characters from Kamen Rider Geats Extra Kamen Rider Punk Jack
Hiroki Amamiya/Kamen Rider Butchi
Portrayed by: Kaname Futaba (live), Yasunari Tsukagoshi (suit)
A member of Win Hareruya's band, Weather Hearts, that transforms into the dalmatian-themed Kamen Rider Butchi. His wish is for said band to be reunited and become popular.Tropes applying to him in general
- Screw This, I'm Outta Here: By the time he appears in the DGP, he's already given up his dream and is running away from the games, forcing the security team to step in. After Win saves him from the Jyamato, Kazuki gives him an ultimatum of continuing or retiring. He chooses the latter.
- Starving Artist: Like Win, he also faced money issues after Weather Hearts disbanded, causing him to join the DGP and hope things turn around. Once he received news about his child is due, he decides that his wish is not worth the risk and gives up being a musician.
Tropes exclusive to him as Kamen Rider Butchi
Armed Hammer! Ready, Fight!
- Animal Motifs: Dalmatians.
- Palette Swap: His helm is a recolor of Groovy's, which makes it another retool of Lopo's.
Kazuki Mashima/Guard Rider
Portrayed by: Kento Ono (live), Rintarō Shimizu (suit)
The captain of the DGP's security team.
- Big Bad Wannabe: Girori could have eliminated him right off the bat, and the only reason he doesn't is so he can use them to test Win.
- Doomed by Canon: Since Girori is still present in the beginning of Kamen Rider Geats, it's obvious that his coup will fail.
- Memory-Wiping Crew: One of the duties of his guards is wiping the memories of dropped or eliminated players.
- Mook Lieutenant: Leads the Guard Riders.
- The Starscream: Launches a coup against Girori, in order to force the latter into granting his wish of ruling the world.
Cloud and Yukito
Cloud portrayed by: Masayuki Sado
Yukito portrayed by: Daichi Hida
Two other band members of Weather Hearts.
- Living Prop: Their only role is filling up the rest of the Weather Hearts band. After Win declares themselves to be disbanded, they disappear without much of a trace.
Characters from Geats Extra: Kamen Rider Tycoon Meets Kamen Rider Shinobi
Rentaro Kagura/Kamen Rider Shinobi
Portrayed by: Hideya Tawada (live), Kotaro Kaji (suit)
See his section under Kamen Rider Zi-O's Future Riders' character page for more details.
Isamichi Konjo/Kamen Rider Hattari/Hattari Yami
Portrayed by: Takuma Zaiki (live)
See his section under Rider Time: Shinobi's character page for more details.
Amakusa Shiro Tokisada/Geronimo
Portrayed by: Shōhei Hashimoto (live)
Yaminin's successor as leader of the Niji no Hebi.
Tropes applying to him in general
- Hero Killer: The fake Previously on… segment implies that he killed the other Shinobi Riders.
- Luke, I Am Your Father: He claims to be Rentaro's father in the fake On the Next segment.
- Named After Somebody Famous: He's named after Amakusa Shirō
(born Masuda Shirō Tokisada), a Japanese Christian from the Edo era who spearheaded the Shimabara Rebellion. His monster form's name is taken from the first Christian name the real-life Amakusa adopted. - Necromancer: He has the ability to bring people back from the dead, as shown with Isamichi.
- Older Than He Looks: Assuming that his claim of being Rentaro's father is true, that would make him at least in his forties, yet he looks no older than 30.
- Villain of Another Story: While he's a major villain in the World of Shinobi, he's not connected to the World of Geats in any major capacity. The only reason Keiwa and Sara are dragged in to the Shinobi plot is due to Amakusa wanting the former's ninja Rider powers.
Tropes exclusive to him as Geronimo
- Katanas Are Just Better: Wields a large one in battle.
- Regal Ruff: Amakusa certainly carries himself like a monarch, and appropriately enough, Geronimo sports a large ruff around his neck.
Characters from 4 Aces and The Black Fox
Mela/Kamen Rider XGeats
Portrayed by: Shohei Osada (live), Takahiro Yoneoka (suit)
A criminal hailing from the future and the mastermind behind the "World Doomsday Game", who transforms into the cross fox-themed Kamen Rider XGeats.
Tropes applying to him in general
The God Killer
- All There in the Manual: The movie's tie-in book, Original Story Book "Who is MELO?", has more information regarding his and Melo's backstories.
- Antagonist Title: Is the "black fox" the movie title refers to.
- Contrasting Sequel Antagonist:
- To Azuma/Kamen Rider Daimon. While Azuma was a human from an ancient civilization that made a deal for immortality, Mela is a digitized being from the future. Azuma was a Tragic Villain who lost faith in humanity due to them repeating the same mistakes without learning from them, Mela is very much a Card-Carrying Villain who is trying to destroy the world for his own amusement. Azuma was a very serious and focused man who was dressed in an all black robe, while Mela is a very flamboyant and showy person who dresses himself in an colorful and over the top manner.
- Both the Paradox Roidmude/108 and Mela are the villains of their respective movies who are from the future and transform into a black-and-blue copy of the main Rider. The Paradox Roidmude was an android who sought a second Global Freeze, disguising himself as Eiji Tomari to do so, while Mela is a criminal with divine powers who treats all of reality as a sport.
- Did You Just Punch Out Cthulhu?: Both him and Melo are notorious criminals in the future wanted for killing so many gods. And yes, they treat it as a sport. According to Original Story Book, Mela and Melo managed to kill both Loki and Susanoo, and Mela created XGeats thanks to Loki's power. What's worse is that once they're done dealing with Ace, their next victim would be another god named Kouta Kazuraba.
- Early-Bird Cameo: He first appears in Rider form in #45 of the main series. Original Story Book reveals that it was an illusion, and that Mela didn't actually transform that time.
- Evil Is Hammy: Good LORD is he ever.
- Meaningful Name: His name has the Japanese word for eye, me (目).
- Psychopathic Manchild: This guy has a complete disregard for any kind of life and has the disposition of a young child in constant sugar rush.
Tropes exclusive to him as Kamen Rider XGeats
Darkness Boost! XGeats. Ready, Fight!
- Dark Is Evil: He is the main antagonist of the film, and his suit is predominantly pitch-black in color.
- Dual Wielding: Wields black-and-blue copies of the Raising Sword and Geats Buster QB9 in battle.
- Evil Knockoff: His overall design is one to GeatsIX, down to the Buckle. Aside from the inverted colors, XGeats's chestplate and shoulder armor have the appearance of a scavenged machine held together by exposed wires and restraints, contrasting GeatsIX's more uniform and bolted-together aesthetic. While GeatsIX is a benevolent Deus est Machina protecting the present using the power of what would be the future even to the DGP, XGeats is a weapon to fracture it for the ends of a man from the DGP's own era.
- Finishing Move:
- XGeats Victory: XGeats rises into the air, spreading his cape out before unleashing a wave of energy that obliterates everything in sight.
- Foil: His Rider name is a mirror to GeatsIX's, X being the Roman numeral for 10.
- Make My Monster Grow: Gets grown to kaiju size, courtesy of Melo.
- Punny Name: In several ways. The "X" is pronounced "Cross", which is spelled kurosu when rendered in romanji, which contains the Japanese word for black (kuro). Going from that, XGeats can sound like Kurosugi Tsu; Kurosugi can mean "Black", "Dark", "Sinister", "Foolish", "Bad", and "Cedar". Tsu can mean "Two" or "Pain". All of these together perfectly describe him: a second Geats who is a dark, black, sinister and foolish bad guy who seeks to inflict pain.
Melo
Portrayed by: Haruka Kudo
Mela's partner.
- Actor Allusion: Melo's nails are colored red, blue, yellow, and silver. This is a reference to the colors of the Lupinrangers in which Umika Hayami, her actress' previous tokusatsu role, is a member of.
- Early-Bird Cameo: Along with Mela, she first appears in #45 of the main series.
- Evil Counterpart:
- To Tsumuri. Like her, Melo is a former navigator who broke away from the confines of her position due to the influence of a fox-themed Kamen Rider. Unlike Tsumuri, Mela never gains compassion for the world and its people, seeking to destroy those things for fun as a part of a game.
- To Ziin, another supporter of a fox-themed Rider with a name derived from an Unsound Effect related to love, an emotional obsession with said Fox Rider, and a need to feel joy through watching DGP games. However, where Ziin preferred to sit on the sidelines and watch Ace save the world before forming a deeper bond and fighting beside him, Melo takes an active role in destroying the world before getting bored of Mela and trying to dispose of him.
- From Nobody to Nightmare: Started out as a navigator named Yu who presented a documentary series on gods. Mela then reprogrammed her to be his partner-in-crime at god-killing.
- Meaningful Name: Her name shares an etymology with her partner's, that being containing me (目), the Japanese word for eye. It can also be doubled up as mero-mero (メロメロ), an onomatopoeia for lovesickness that makes one lose self-control, the way she obsesses over Mela and his games.
- Screw This, I'm Out of Here!: Seeing Mela being beaten by Geats, Melo decides she's now bored of him and decides to blow him up along with the tree and Ace. Luckily, Tsumuri knocks her out before she could proceed.
Opabinia Jyamato
Portrayed by: Danki Sakae (suit)
Mizuginote Jyamato
Jyamato dressed in swimsuits.
Houtaro Ichinose/Kamen Rider Gotchard
Portrayed by: Junsei Motojimanote (voice), Eitoku (suit)
- I am Kamen Rider Gotchard! An alchemist who's chasing after big dreams!
An alchemist Kamen Rider who arrives to aid Keilow in his fight against a gang of Jyamato.
The tropes listed below are in relation to his Early-Bird Cameo; for tropes pertaining to his home series, see his folder under Kamen Rider Gotchard.
- Early-Bird Cameo: He first appears in Geats' summer movie before his series. He would later appear in the finale chasing after Hopper1.
- Magic Knight: Makes liberal use of alchemy during his fight with the Jyamato, along with his Rider powers.
- Small Role, Big Impact: He provides Keilow with a blank Ride Chemy card as an apology for mistaking him for an enemy, which becomes the Oneness ver. of the Kamen Rider Geats card for the Oneness Raise Buckle.
- Would Harm a Senior: Implied when he first encounters and manhandles Keilow, who calls him out for the rough treatment on the elderly. He initially justifies it under the Wrong Assumption that he's also a bad guy until Hopper1 clarifies the issue.
- Wrong Assumption: He initially assumes Keilow to be part of the Jyamato, until Hopper1 corrects him on his misconception.
Characters from Kamen Rider Geats: Final Stage
Clover/Kamen Rider Gazer (II)/Jyamato Gazer
Voiced by: Kenta Miyake
A hammy evolved Jyamato who steals a Vision Driver and credentials for Kamen Rider Gazer.
- Large Ham: About as loud and bombastic as you'd expect one of Kenta Miyake's performances to be.
- Palette Swap: Jyamato Gazer is a green-colored version of Gazer.
- Revenge: His ultimate goal is to exact vengeance upon all of humanity for the Riders protecting them from the Jyamato, ever since Ace and gang beat them back. He also notes that a clover (a four-leaf one to be precise) is a symbol of revenge.
Characters from Jyamato Awaking
Future Ace/Kamen Rider Dooms Geats
Portrayed by: Hideyoshi Kan (live), Kotaro Kaji (suit)
A version of Ace Ukiyo hailing from an alternate timeline, sent by Niramu to stop the God Jyamato from awakening. He transforms into Kamen Rider Dooms Geats, a gold Rider who resembles GeatsIX.
Tropes applying to him in general
- Alternate Self: He's an alternate version of Ace.
- Anti-Villain: Essentially, he's sent back from the future to kill the God Jyamato before it can destroy the world. A noble intention; it's just that he thinks anyone who tries to stop him or was involved in the catastrophe should be violently swept aside.
- Bad Future: The future where Future Ace is from is being destroyed by the aforementioned God Jyamato.
- Big Bad Ensemble: If you could even call him a Big Bad, he shares this role with Aoto/the King Jyamato. Dooms Geats is a prevalent thorn in the main cast's sides, trapping Ace in a separate dimension for the majority of the film and clashing blades with Michinaga, who wants to save Haruki rather than outright kill the boy.
- Expy: Of Geiz, being a Kamen Rider from a Bad Future who traveled to the present in order to execute the one responsible before their destructive powers fully manifest.
- Restored My Faith in Humanity: After witnessing Michinaga avert the doomed future he comes from by showing kindness and understanding to Haruki, he returns to his time, once again believing in humans, especially seeing that the future was able to be changed for the better.
- Shadow Archetype: He's a version of Ace who has given up on humanity's ability to change the world for the better.
- Took a Level in Cynic: Outliving his friends made him no longer believe in a future where everyone could be happy.
- Who Wants to Live Forever?: As an immortal god, Future Ace naturally outlived Keiwa, Neon, and Michinaga. Feeling like everything he did as a god was All for Nothing is what ultimately leads him to abandon his ideals and become ruthless.
Tropes exclusive to him as Kamen Rider Dooms Geats
Dooms Buckle voiced by: Yoshitsugu Matsuoka
Judgement Boost! Dooms Geats. Ready, Fight!
- Finishing Move:
- Dooms Geats Strike: Dooms Geats charges his sword with energy and unleashes a crescent wave at the enemy.
- Dooms Geats Victory: Dooms Geats summons an energy construct of Boostriker Geats Mode, which performs a charging attack on the enemy.
- Palette Swap: Dooms Geats is a gold recolor of XGeats. He also uses a golden GeatsIX buckle and Geats Buster QB-9.
- Red Eyes, Take Warning: Has a red visor, and is a major antagonist of the film.
- Rule of Symbolism: The Dooms Geats buckle incorporates the voices of the Vision and Zillion Drivers, symbolizing how this version of Ace is so badly broken to the point of casting aside his morals and idealism to survive.
Hazuki/Queen Jyamato
Portrayed by: Arisa Matsunaga (live), Ayumi Shimonozo (suit)
A mutant breed of Jyamato that fell in love with a human man and gave birth to what would become the God Jyamato.
- Died in Your Arms Tonight: She perishes in the arms of her son after being defeated by the King Jyamato.
- Evil Counterpart: Subverted. Of Mitsume, both possessing the power of Creation which their respective sons inherited.
- Expy: Of Maya, being a member of a race of monsters who can take human form, has "Queen" in her title and thus apparently an elite, and who falls in love with a human, even bearing children with him.
- Interspecies Romance: With Kiyoharu.
- Reincarnation: She's one of Miil in a sense, having been created from the flower left behind from the Rook Jyamato that devoured her.
- Roaring Rampage of Revenge: Does not take kindly to Aoto killing Kiyoharu.
Kiyoharu Usajin
Portrayed by: Masahiro Usui
Hazuki's husband.
- Go Through Me: He puts himself in front of Aoto to protect his family, and gets shot and killed as a result. It's implied that this was intentional on Aoto's part.
- Interspecies Romance: With Hazuki.
- Nice Guy: He's an amiable fellow who doesn't care that Hazuki is part-Jyamato and loves her all the same.
- Sacrificial Lamb: Is shot and killed by Aoto in "self-defense" early on in the story, inciting Hazuki's rampage as the Queen Jyamato and kicking off the main plot.
- Through His Stomach: He managed to get Hazuki to fall in love with him in part through sharing some melon bread with her.
Haruki Usajin (spoilers)
Haruki Usajin/God Jyamato
Portrayed by: Minato Shogaki
Hazuki and Kiyoharu's son.
- Break the Cutie: Is the target of this by Aoto via the latter murdering his parents, hoping that his resulting hatred for humans would trigger his turning into the God Jyamato. Thanks to Michinaga, however, it never comes to pass.
- Combat Tentacles: Possesses these in his God Jyamato Form.
- Deceased Parents Are the Best: Loses his mother and father over the course of the film.
- Expy: He's one to Chihiro, as he's another Half-Human Hybrid who is not only far younger than he looks, but also uses Combat Tentacles after his mother dies and his superpowers awaken. His God Jyamato form takes after the Orphnoch King, being a figure whose existence is revered by lesser members of his kind and manifests from a child.
- Evil Counterpart: Subverted. Of Ace, both being Half-Human Hybrids who inherited the Power of Creation from their respective mothers. But while Ace's mother is a navigator who became the Creation Goddess, Haruki's mother is a Jyamato who inherited the traits of a navigator who had not awakened as a Creation Goddess.
- Happily Adopted: By his grandfather Daichi at the film's end.
- From Nobody to Nightmare: From ordinary (or as ordinary as a half-Jyamato) boy to a future destroyer of mankind.
- Tyke Bomb: This seemingly ordinary boy turns out to be the larval form of the God Jyamato that would doom the future.
- Woobie, Destroyer of Worlds: He's just an innocent, harmless little boy, right? Well, it turns out his mother is a Jyamato who assimilated the traits of a navigator that was created to replicate Mitsume's powers — so technically, he inherited both Jyamato DNA from his mother along with the potential to harness the power of Creation. That alone should be a red flag, but that isn't enough. When his parents got killed by the King Jyamato... oh boy, he hits his breaking point and goes apeshit when he becomes a Jyamato with all the fully manifested abilities of a Creator God, revealing that he's the future God Jyamato that would bring doom to all of humanity.
- Younger Than They Look: He looks to be around ten years old, but is revealed to only be a few months old at most.
Aoto (spoilers)
Aoto/King Jyamato
Portrayed by: Keigo Hagiya (live), Kenya Saitō (suit)
A police officer who was at the scene of the Queen Jyamato's rampage, who may just have more to do with the events than it seems.
Aoto is later revealed to be the human identity of the King Jyamato, who seeks to awaken Haruki's powers as the God Jyamato by murdering both of the boy's parents.
- Bandaged Face: In scenes where he plays the human identity of the King Jyamato, he's shown with a heavily bandaged face, disguising the fact that he is also the officer who shot Kiyoharu dead.
- Big Bad Ensemble: Aoto shares the role of main antagonist with Future!Ace, though while the latter is more of an Anti-Villain, the King Jyamato has no scruples about dooming the humanity and causing the Bad Future that Future!Ace came from by driving Haruki to despair.
- Chekhov's Gunman: He's first shown as a seemingly ordinary police officer who's looking for a runaway child. Of course, it's later revealed that it's because he's looking for the child and his mother, who both have a role in his plans.
- Evil Cannot Comprehend Good: He has no understanding of love, nor does he want to understand it.
- Hate Sink: He's the most despicable of all of Jyamato, to the point of murdering Queen Jyamato and her husband, psychologically breaking their son into destroying all of humankind, and even attempting to break Ace's faith in humanity.
- Humans Are Bastards: He's a firm believer in this to the point where not only does he reject Daichi's directive of learning what love is (unlike Hazuki who chose to try and succeeded), but he also takes steps to ensure his fellow Jyamato share his views.
- You Killed My Father: He's the murderer of Haruki's parents — Kiyoharu as a human, and Hazuki as the King Jyamato.
Characters from Geats Extra Kamen Rider Gazer
Nemeru/Kamen Rider Gazer Zero

Tropes applying to him in general
The renegade former Producer
- Disappears into Light: Dissolves into motes of white data upon his defeat at Niramu and Ziin's hands.
- Evil Counterpart: To Ace, both ending on Suel's bad side and declaring war on the DGP. While Ace's motives are to free his mother from the production staff, Nemeru acts out of spiteful revenge.
- Evil Is Petty: Seeks the complete destruction of the DGP — including the staff and audience — as revenge for his getting fired.
- Foil:
- To his successor Niramu, both being DGP Game Producers and their names being variants of "gaze". Nemeru was willing to resort to any means to make the DGP entertaining, while Niramu drew the line at using Tsumuri as the new Goddess of Creation.
- Also to Beroba as both are manipulative and Faux Affably Evil figures who utilize the Jyamato for their goals to acquire the power of the Goddess of Creation - Beroba going after the goddess directly while Nemeru targets a potential successor and feeds her to the Jyamato.
- Greater-Scope Villain: He was the one responsible for DGP utilizing the Jyamato, making him responsible for every causality the Jyamato case in the series. He is also the reason that Jyamato designed to evolve.
- Hero's Evil Predecessor: For a given definition of "hero"; he was the DGP's game producer before Niramu.
- Kick the Dog: As though causing the death of a DGP Participant via his direct intervention wasn't enough, he deliberately prevents Niramu from saving Miil from being eaten by the Rook Jyamato. He then proceeds to mock Niramu over her death.
- Meaningful Name: His name is derived from 睨める, which is Japanese for "to glower [at]".
- Real Men Wear Pink: His wardrobe features a pink jacket over a pink-and-white shirt, and he's no slouch in a fight. He's also the main villain.
