This is a partial character sheet for Kamen Rider Zi-O. Visit here for the main character index. Subjective trope and audience reactions should go on the YMMV page.
Kamen Riders from a future that normally shouldn't exist, whom Sougo and Geiz encounter. They exist in the same Alternate Timeline that White Woz hails from, one where Geiz defeated Zi-O on the Day of Oma. As such, their existence depends on the original timeline not coming to pass.

Overall
- Fighter, Mage, Thief: The three future riders can be considered this.
- Shinobi is the Thief of the trio, because of his speed, agility and skills as a ninja.
- Quiz is the Mage of the trio, because of his powers to use quizes to shock enemies and lack of power or speed compared to the other two.
- Kikai is the Fighter of the trio, because of his monstrously huge strength and lack of speed.
- Hero of Another Story: As future Riders, they have their own conflicts to fight in. Shinobi's adventures, at least, were chronicled in his own miniseries on the Toei Tokusatsu Fan club website, while it's unknown what Quiz fights against and Kikai's adventures were shown in the series during his "tribute" arc. The only exception is Ginga, who is a Villain of Another Story; a Dark Rider whose goal is galactic conquest.
- Living Dream: These riders seemingly don't exist in the Oma Zi-O timeline but rather than being heroes who arose because Geiz defeats Zi-O, they're Sougo's dreams which he is unwittingly bringing into existence. Each has an element of this, most telling of their belts being retooled black Ziku Drivers, but it's most apparent with Kikai, who was born after Sougo was reminded of the toy robot he had as a child and him dreaming about a future where a heroic machine defends the humans of his era.
- My Rules Are Not Your Rules: In contrast to the Ridewatches, which erase the existence of the Riders they steal the powers of, the Miridewatches affirm the creation of the future Riders, and in so doing bring their potential future closer to becoming the one true reality.
- Production Foreshadowing: The next series after Zi-O, Kamen Rider Zero-One, combines elements from all three future riders. Since they originated as Sougo's dreams, while Zero One takes place in the new timeline which Sougo created at the end of the series, they can be considered Zero One prototypes even in-universe.
-
Prop Recycling: The future Riders reuse parts from past Rider seasons:- Kamen Rider Shinobi reuses the head and shoulder pads from the Ride-Players, and the body, legs and arms of the Dark Necrom and Parka Ghost bodies.
- Kamen Rider Quiz reuses the head from Kamen Rider Ghost and the bodysuit from the Ride-Players.
- Kamen Rider Kikai reuses one of the Guardian suits from Kamen Rider Build.
- Kamen Rider Ginga reuses the bodysuit of Fourze Meteor States, with the lower legs coming from Meteor, and the helmet from the Mage suits.
- Kamen Rider Hattari reuses the Dark Drive suit.
- Spanner in the Works: They, by all rights, should not exist, since Oma Zi-O's rise would mean there aren't any other Riders to succeed him.
- Temporal Paradox: The three future riders seemingly come from the timeline where Geiz defeated Oma Zi-O as Geiz Revive. However to do so Geiz needed their 3 Ridewatches, the existence of which mean that all three riders had their histories altered and never gained their powers in the first place. They are either a subversion of the Grandfather Paradox or may well come from a third timeline separate from White Woz's. The show seems to have settled on a subversion: that their watches exist actually affirms their existence, meaning they will become Riders eventually...allowing their powers to be pulled back in time in the first place, creating a inverse of the normal loop usually created by the birth of a Ridewatch. That said, only White Woz can perform this loop since he's from the timeline in question, and thus can draw from it. Further complicated when it's revealed that the future riders only exist because Sougo's time manipulation powers are creating potential futures without his meaning to. The ultimate revelation of how Sougo has unwittingly been relating the various Kamen Rider Worlds smooths this out somewhat, moving the future Riders into the realms of parallel rather than alternative timelines.
- Transformation Trinket: All of the future Riders use the Mirai Drivers, which resemble matte black Ziku Drivers. Additionally, each of them has an accessory that can be strapped to the Mirai Driver to transform them. Also, while "Mirai Driver" is the catch-all term for these belts they actually do all have unique names matching their respective rider.
- Unwitting Instigator of Doom: Of sorts. The more that Zi-O and Geiz interact with these future Riders and bring about the creation of their Miridewatches, the more real their timeline becomes, and the more inevitable that Zi-O's death at Geiz's hand becomes. The way White Woz tells it, this sounds like a great thing, but the other characters aren't so convinced that his future is as perfect as he makes it out to be. And they were right; turns out White Woz’s future was a future that benefits only him, as Geiz Revive, created by the first three Miride Watches, would have killed Geiz in the process.
- The potential for the Geiz Revive Timeline to come to pass is no longer possible after Sougo and Geiz patch things up, removing White Woz from existence.
Rentaro Kagura/Kamen Rider Shinobi
Rentaro Kagura/Kamen Rider Shinobi
Portrayed by: Hideya Tawada (live), Yuji Nakata (suit)
- "Writing the way of Shinobi with the blade of my heart! Kamen Rider Shinobi!"
A nervous young man who nevertheless possesses a great sense of justice in the present time, who is destined to become a noble, mysterious, and flashy ninja in the year 2022. He transforms into the ninja-themed Kamen Rider Shinobi.
Tropes that apply to him in general
- The Ace: The opening for Rider Time: Shinobi says he's the legendary shinobi and the First Volume has him easily beat Kamen Rider Hattari.
- Actor Allusion: Kamen Rider Shinobi/Kagura Rentaro was previously StarNinger, and if that's not enough, his Rider belt has a spinning shuriken and this soundbyte:DARE JA?! ORE JA!! NIN-JAAAA!!
- Animal Motifs: Frogs. It's to the point that the theme is a main part of his Transformation Sequence.
- Ascended Extra: He's the protagonist of his own spin-off called Rider Time: Shinobi.
- Being Good Sucks: The reason he took up the request to become Another Shinobi in 2019; for all his sense of justice, he was too weak to actually save anyone. He later grows out of it thanks to Sougo.
- Beneath the Mask: That image of a completely inept, amateurish ninja we've seen for the first half of First Volume? A complete and total charade there to mask the One-Man Army underneath everyone's noses.
- Beware the Silly Ones: This seemingly bumbling older brother is more than capable of delivering a world of hurt to anyone foolish enough to provoke him into doing so.
- Big Brother Instinct: Is hellbent on protecting his little sister from the Dark Ninja Army. Especially since she's the current Rainbow Serpent Clan princess. And the sibling relationship between him and his sister is quite genuine.
- Breakout Character: His first appearance was well-received and given positive feedback by fans and viewers, so as a result, Rentaro is the only Future Rider having his own spin-off minseries, Rider Time: Shinobi. He returned once more during Kamen Rider Geats for a TTFC special with Tycoon and the other past Ninja Kamen Riders.
- Brought Down to Badass: Even with losing his ability to transform and use ninjutsu, Rentaro is still a very capable fighter.
- Catchphrase: He says (as seen above), "Writing the way of Shinobi with the blade of my heart! Kamen Rider Shinobi!" after his transformation. Just before performing his Finishing Move, Shinobi proclaims "Going Forth!"
- Childhood Friends: He and his sister Iroha were friends with Isamichi when they were young.
- Experienced Protagonist: Is already a ninja few can hope to ever compare to by the time we meet him again in his series.
- Heroic BSoD: The combination of losing his ninja powers, failing to prevent Irona from getting kidnapped, and Isamichi dying to save his life renders Rentaro completely depressed for a good chunk of the Kamen Rider Tycoon Meets Kamen Rider Shinobi special.
- He's Back!: In the Kamen Rider Tycoon Meets Kamen Rider Shinobi special, he's able to transform again after witnessing Keiwa's resolve.
- My Sister Is Off-Limits: Downplayed; he's noticeably uncomfortable when Isamichi talks about his crush on Iroha, but he never tries to stop Isamichi from dating her either.
- Nice Guy: A kind and strong-willed young man who desires justice. Unfortunately for 2019 Rentaro, he's too weak to be effective, but he gets better in 2022.
- Obfuscating Stupidity: And how; he managed to fool everyone up to and including his childhood friend and own sister into believing he's incompetent when it comes to anything regarding ninjutsu.
- Paper-Thin Disguise: Whether dressing up as a ninja referee or a business man, Kagura is clearly seen in disguise, but manages to trick everyone anyways. Kagura even had to use Isamichi's brightly colored ninja scarf to hide his face from sight. And Isamichi actually falls for it!
- Perpetual Poverty: Iroha complains about his low salary, which regularly gets their power cut. Though this is due to Rentaro cutting work to protect her and getting his pay docked as a result.
- Playing with Fire: His Strong Ninpo, which can fire a stream of purple flame from his hand. Shinobi can also coat his body in his flames to shield him from attacks.
- Purple Is Powerful: While more prominent in his Rider form, his civilian clothes has traces of purple. His energy aura is also in purple too.
- Ret-Gone: 2022 Rentaro was temporarily overwritten when his 2019 self became Another Shinobi, but 2019 Rentaro's resolve to fight with his own strength led to his timeline being restored.
- Temporal Paradox: His becoming Kamen Rider Shinobi. Becoming Another Shinobi in 2019 allowed him to meet Sougo, whose moral support gave him the courage to fight as Kamen Rider Shinobi in the future. Yet Another Shinobi's powers came from his future Kamen Rider self to begin with, completing the loop.
- The Unchosen One: He's only a Shadow Warrior for Shinobi, a substitute till Iroha, the real inheirtor, turns 18 to take over.
- Willfully Weak: Has the skills that would make him the ultimate ninja, yet consistently puts up the image of being the opposite. Best demonstrated in the first episode when during a match with Iroha, he seemingly fibs on using a fire technique. Later in that same episode, he effectively uses this very same move to cancel out Kamen Rider Hattari's own ice ninpou, allowing Shinobi to overpower and defeat him.
Tropes exclusive to him as Kamen Rider Shinobi
Dare ja?! Ore ja! Ninja! Shinobi kenzan!note
- Blow You Away: The Megaton Ninpo is able to create a cyclone.
- Cool Sword: His unnamed Ninjato.
- Doppelgänger Attack: Rentaro creates multiple clones alongside him to attack together. They are also able to perform Ninjutsu techniques.
- Fragile Speedster: Overlapping with Squishy Wizard. Among of the Future Riders, he is the fastest in terms of speed and agility. Combined with his wide array of ninja skills, he is a force to be reckoned with.
- Frog Ninja: A giant frog called "Oogama" appears in his Henshin sequence, and he's a ninja.
- Finishing Move: Finish Ninpo: Shinobi attacks his opponents in high speed movements while shrouded in purple aura. And there are variations of his move:
- In his first appearance in Zi-O, Shinobi does a combination of punches before doing a spinning kick.
- In his battle against Hattari, Shinobi makes a combination of slashes with his Ninjato before doing a spinning final slash.
- In the battle against Yaminin, Shinobi uses Seibai Ninpo, a combination of Strong Ninpo and Megaton Ninpo that sends his Yaminin flying, before summoning multiple clones of himself to attack Yaminin all at once, using two clones to launch Yaminin even higher, and finally finishing Yaminin with a bicycle kick shrouded in aura, sending Yaminin crashing down to earth.
- Highly-Visible Ninja: He has bright purple armor, which makes him stand out quite a lot. Of course this is in a brightly lit environment, if the area is dark and/or at night he'd be considered less visible.
- Humongous Mecha: His transformation is provided courtesy of a giant robot frog called the Kuragane Oogama note Which supplies weapons, armor and other equipment.
- Instant Awesome, Just Add Ninja: The basis of his Rider design is the appeal of ninja.
- Making a Splash: Can fire powerful jets of water.
- Reverse Grip: He wields his Ninjato this way.
- Ninja Log: Rentaro quickly substitutes himself with another object such as a scarecrow or a ragdoll, allowing Rentaro to flee and/or hide.
- Scarf of Asskicking: Possesses a shiny purple scarf in his Rider form due to his ninja motif.
- Spin Attack: Shinobi can unleash a spinning slash that creates an aura image of a giant shuriken spinning.
- Stock Ninja Weaponry: As expected of a ninja character, Shinobi uses his Ninjato as his weapons and is shown to use shurikens as well.
- Technicolor Fire: The flames he produced are purple in color.
Mondo Douan/Kamen Rider Quiz
Mondo Douan/Kamen Rider Quiz
Portrayed by: Katsuhiro Suzuki (live), Yuji Nakata (suit)
- "Saving the world,note and obtaining the right answer!note Kamen Rider Quiz!"
A smug genius with a love for quiz games from the year 2040, who followed White Woz back to 2019 to uncover the truth behind his father's Parental Abandonment, unaware of White Woz's plan to have Geiz defeat him for his powers. He transforms into the Quiz game-themed Kamen Rider Quiz.
Tropes that apply to him in general
- The Dandy: Fashion is even mentioned in his transformation jingle!
- Insufferable Genius: He is a genius in and out of combat and will let people know it every time.
- Jerk with a Heart of Gold: Mondo is very cocky, referring to both Geiz and Sougo as "twerps" after beating them. But he came to the past to find out if his father truly loved his mom and help his sick mother move on.
- Manly Tears: He starts crying when he learned that his father truly did love his mother.
- Maybe Ever After: Familial, rather than romantic. While Mondo had no intention of trying to change the past, his broken wristwatch begins working again when all's said and done, suggesting that perhaps his father had a change of heart and the future waiting for him back in 2040 is brighter than the one he left.
- Meaningful Name: His name is a pun on the Japanese words for "Question" (問答/Mondō) and "Answer" (答案/Tōan).
- Momma's Boy: A positive example as he seems to deeply care for his mom. Even traveling to 2019 because of White Woz to help her.
- Set Right What Once Went Wrong: Averted. Quiz states he has no intention to change the past.
- Tragic Keepsake: He wears a broken wristwatch that used to belong to his father. As a result of Mondo going to the past, it's working again.
Tropes exclusive to him as Kamen Rider Quiz
Fashion! Passion! Question! Quiz!
- Armor-Piercing Question: A more literal example than most, and weaponized. One of Quiz's abilities is the power to ask a True/False Question to his enemies. Should they answer wrong, they'll be damaged by electric shock. Unfortunately for his enemies, Quiz decides what the answers are.
- Confusion Fu: His fighting style in a nutshell. And he is very good at it.
- Cutting the Knot: While Quiz does have a vast memory of trivia, he instead asks questions with answers he can manipulate ("Will your attack miss?" True if he dodges).
- Deadly Game: His to play a quiz game with his opponents, with the punishment for a wrong answer being a powerful and painful electric shock.
- Difficult, but Awesome: His primary power is this. While extremely effective and making him insanely hard to beat in a straight fight, as shown with Kamen Rider Woz later on, they require a good bit of skill and intelligence to use, something Mondo has in abundance.
- Finishing Move: Final Quiz Flash: Quiz jumps in the air only to be hidden by a giant sign with two panels marked "O" and "X" respectively. He then breaks through the correct panel with his foot, resulting in the two symbols combining, and kicks the enemy.
- Primary-Color Champion: His color scheme is Red and Blue with hints of white.
- Sigil Spam: His Rider form is covered with question marks.
- Squishy Wizard: His official stats reveal he is actually a bit weaker than Geiz and Zi-O, but physical combat is rarely an issue when simply asking questions is all he needs to hurt them.
- Story-Breaker Power: His powers let him hurt opponents by asking them questions they can't answer, which combined with his extensive knowledge, means he'd be essentially impossible to beat in a straight fight. It's a bit fitting that White Woz can only take away his power and encourages attempts to do so when he's untransformed.
Rento Makina/Kamen Rider Kikai
Rento Makina/Kamen Rider Kikai
Portrayed by: Jingi Irie (live), Yuji Nakata (suit)
- "A body of steel, and fire in my heart! Kamen Rider Kikai!"
A Humanoise with a change of heart from the year 2121, who fights the Humanoise, human-like androids that have taken over the world in his era. He transforms into the machinery-themed Kamen Rider Kikai.
Tropes that apply to him in general
- Actor Allusion:
- Rento's actor, Jingi Irie, previously played the rebooted version of Kikaider.
- Kikai having ice manipulation abilities is an obvious reference to his actor's other previous role as Zamigo Delma.
- Deceptively Human Robots: If not for his monotone speech and occasional jerky movement, it wouldn't be clear he was a machine.
- Friend to All Children: Kids love him, and as seen with him showing off his powers in front of them, he has a soft spot for them as well.
- Gone Horribly Wrong: His attempt to recharge himself at the end of his debut episode goes south when the signal is hacked, causing him to be infected with Humanoise programming, go berserk and attack Sougo.
- Heel–Face Turn: #24 reveals that Rento was initially part of the Humanoise invasion party. Befriending a group of children was enough to get him to switch sides.
- Imaginary Friend: He's the physical manifestation of Sougo's only childhood friend, the toy robot he used to play with as a boy, unknowingly created by Sougo with his latent time manipulation powers.
- In Spite of a Nail: If his timeline came true, the world in 2068 would have been saved from Oma Zi-O's rule, yet another fifty-three years down the road the world was still taken over anyways, this time by the Machine Lifeform Humanoise. It's at least somewhat of an improvement, as unlike Oma Zi-O, Kikai is capable of standing against them.
- Meaningful Name: His last name, Makina, is a pun on the word "machina".
- Phlebotinum Rebel: Rento was originally one of the Humanoise who hunts down humanity to near extinction until he switched sides and became a Kamen Rider to defend a group of children from his former brethren.
- Pick Your Human Half: Makina looks completely Human on the outside, but has a monotone voice and moves somewhat clumsily. It makes sense, since he's a machine.
- Shout-Out: His rider name, clothes, motif, and actor are an homage to Kikaider.
- One of the words the Kikai Driver cries out during transformation is "Hakai!", which alludes to Kikaider's arch enemy Hakaider. This lore also representing one of his finishing moves, Kikai Will Destroy (Kikai de Hakai da), is a pun on both Kikaider and Hakaider.
- Token Non-Human: He is the only future rider that isn't human, but is a Humanoise instead.
Tropes exclusive to him as Kamen Rider Kikai
Dekai! Hakai! Goukai!note Kamen Rider Kikai!
- Bling of War: Much like Kamen Rider Grease, who his mugshot resembles, Kikai is a gold-colored Rider.
- Finishing Move: By touching both sides of the Kikai Driver, Kamen Rider Kikai can initiate one of three attacks:
- Kikai De Hakai Danote : Kikai generates electrified ice energy from his belt and channels it through his right foot as he executes a spin kick.
- Ultimetal Finish: Kikai channels his electrified ice energy through his right arm and executes a punch powerful enough to destroy the object.
- Fullmetal The End: Kikai generates a large amount of electrified ice energy throughout his upper body and jumps high, and the energy transfers to his right foot and solidifies into a large icicle that penetrates the target.
- Mighty Glacier: Being a robot, Kikai is stronger and tougher than even Zi-O and Geiz combined, but he’s also the second heaviest rider in the franchise and the heaviest of the Heisei Era. * and thus far slower than them.
Kamen Rider Ginga
Portrayed by: Tomokazu Sugita (voice), Yuji Nakata (suit)
- "Decay is the fate of all things."
Gin-gin-gira-gira-Galaxy! Uchū no kanata no Fantasy! Kamen Rider Ginga!
An extraterrestrial Kamen Rider from a fracture in the space-time continuum. He arrived on Earth through a meteor and intends on conquering the planet along with the entire universe.
While technically not part of the same "Future Riders" group as the other three (as he's not from the future and not heroic), he's listed here because he does have some aspects in common (he's a Canon Foreigner that Woz gets a Miridewatch from).
- Asskicking Leads to Leadership: He believes that his power gives him the right to rule everything. Considering how powerful he is, it is hard to challenge him.
- Badass Cape: He wears a purple cape.
- Badass Boast:Kamen Rider Ginga: "I am of the cosmos. The laws of your world do not apply to me. There is but one everlasting law that applies to all throughout the universe..."
- Came from the Sky: Arrived to Earth from a meteor sometime in the future.
- Casting Gag: Two cases: His voice actor is the voice of the Kivat family in Kamen Rider Kiva, as the Kiva arc is Ginga's debut episode. Additionally, his voice actor is also the titular hero of Ultraman Ginga, as well as the fact that both characters are from the future.
- Celestial Body: Ginga's body has stars, planets, and the Sun itself.
- Diabolus ex Nihilo: Other than being voiced by Kivat's voice actor, he has no relevance to the Kiva Arc and basically just comes out of nowhere to announce his presence and interrupt the fight with Another Kiva. He fell from the sky out of nowhere just to be invincible for a minute or two and then defeated so Woz can get a Super Mode. Not even a head-fake towards making him a real character or part of the story (of the season or even the episodes he's in.) Though he is used to show that time is being warped, which is a major focus in the Kabuto arc right after.
- The Dreaded: Even Swartz showed signs of fear of his presence.
- Enemy Mine: Ginga is so powerful, that it takes the combination of the heroes, along with the Time Jackers and Another Kiva with her followers fighting together just to barely defeat him.
- Evil Sounds Deep: He possesses a very deep voice, which just reinforces how threatening he is.
- Finishing Move: 3 of his own: Gigantic Ginga, Dynamite Sunshine and Strike the Planet 9.
- Flying Saucer: Ginga's motif involves UFOs.
- Foil:
- To Oma Zi-O, as both are beings who aim to dominate all they see with their immense power. While Oma Zi-O is a golden-armored king with power over time that the Time Jackers seek to create, Ginga is a purple-armored invader with power over space that even the Time Jackers fear.
- And to Yuko Kitajima/Another Kiva as he appeared in her arc. They both think that their power allow them to take control of the world. But while Ginga is transparent on his intentions, Yuko lies to everyone around her including herself that she was wronged when she's just a murderer who only cares about getting her way.
- Galactic Conqueror: His ultimate goal is to conquer the universe itself...
- Generic Doomsday Villain: He is an evil Kamen Rider who wants to conquer the universe and that's all we know of him. He doesn't even have a civilian identity to speak of.
- Gravity Master: Supplementary materials reveal him to be able to manipulate gravity for flight and offense, demonstrated in combat by forcing Woz’s scythe to be stuck in the ground.
- Knight of Cerebus: The only future Rider to be an outright villain, almost as powerful as Oma Zi-O, and at the same time poses a serious threat to both the Riders and Time Jackers. Even Swartz can only shudder in fear the instant he felt Ginga's presence on Earth. Ginga would go as far to singlehandedly manhandle Zi-O Trinity with barely little to no effort at all.
- Master of All: Ginga is more agile than Shinobi, his energy manipulation makes Quiz's powers look like child's play, he is also stronger than Kikai and to top it off his stats even surpass Zi-O Trinity to the point where his Miridewatch can bypass the restrictions on destroying Anotherwatches.
- Mythology Gag: He and the arc he's in are essentially one to criticisms of the plot of Kiva as a whole, and in particular to its infamous ending, in which alien vampires from the future appear without explanation just to give the show a Bolivian Army Ending.
- Outside-Context Problem: He just suddenly appeared out of nowhere and has no ties with the Time Jackers, Another Riders, Sougo's powers nor is he even a part of Geiz Revive's powers like the other future riders. In fact the only reason he can be considered a Future Rider is because he uses a Mirai Driver like them.
- Person of Mass Destruction: His energy manipulation power gives him the ability to create ridiculously powerful beam attacks which can cause massive explosions.
- Power of the Sun: He gets his energy from the sun. When storm clouds came in and covered the sun after taking a major hit, he turned into a crystallized statue and turned back when the sun came back out.
- Purple Is Powerful: He is powerful enough to overpower Trinity Form without even having to touch him.
- Screw This, I'm Out of Here!: After getting defeated by Zi-O, Geiz, and Woz, he explodes, and is last seen fleeing the Earth as a pillar of light as some of his essence is used for the GingaFinaly Miridewatch.
- The Social Darwinist: See his Badass Boast above. He believes that only one's own strength gives them the right to rule over everything else.
- Super Power Lottery: Almost as much as Oma Zi-O. He is capable of flight, traveling through space, can manipulate gravity, and manipulate energy which he can use to create powerful energy blasts and force-fields. In his case, it is a bit justified since Ginga is an alien and thus has power far surpassing that of a human being. The riders only defeat him by attacking him after he has been weakened by darkness and even then, he seems to survive and just chooses to leave.
- Well-Intentioned Extremist: It is implied through his dialogue before being temporally crystallized under a shade that his intention is to stop Another Kiva. Or maybe the real Kiva. It's not particularly clear.
- The Worf Effect: To show the extent of his threat, he shoots down Another Kiva without so much of a glance and beats up Zi-O Trinity with little effort.
