    DenLiner Crew 

Ryotaro Nogami/Kamen Rider Den-O (portrayed by Takeru Satoh and Takuya Mizoguchi)

The protagonist and eponymous Kamen Rider, Ryotaro is quite possibly the unluckiest being on Earth (and a high school drop-out supporting his only other family member, his older sister Airi); every day is a parade of misfortune for him. In the middle of an unusually bad day, he's possessed by a time-travelling monster called an Imagin, meets a strange girl who tells him he's a Singularity Point, and said girl and Imagin effectively "railroad" him into becoming Den-O. Even though by his own admission he's not exceptionally strong, smart, or brave, when the chips are down his true strength appears in the form of unstoppable determination. In a way, his horrid luck could be seen as a mixed blessing, since he's been through so much that it takes a lot to really faze or hurt him. He's also very good at reading people's emotions and true feelings; Ryotaro's ultimate strength may lie in his unflappable kindness. His strong feelings towards his friends are the reason for the existence of Den-O's first Super Mode Climax Form, while the Taros work together to create the second, Liner Form. As well, Ryotaro's bond with the Taros is the reason they continue to exist after the death of Kai. As the series went on, he started to develop self-confidence, assertion, strength, and bravery, eventually being able to show himself as an independent person and a worthy hero

  • Calling Your Attacks: Hissatsu Waza!...um...Densha Giri! note  The crew's reaction?
    The Crew: Your naming sense is terrible!
  • Catchphrase: "Let's go, Everyone!" note  settled in after he gained Liner Form.
  • Classical Anti-Hero: Incredibly clumsy, weak and unlucky, with his saving grace being strong morals and an absolute refusal to compromise them.
  • Cool Sword: DenGasher Sword Mode (used a couple of times in Plat Form and once in Liner Form in Final Countdown when he lost the DenKamen Sword).
  • Cosmic Plaything: After seeing the scene where he's whacked in the face with progressively larger balls (as in sports equipment), can you really call him anything else?
  • Cowardly Lion: He's very afraid the few times he's forced to fight, but he stays anyway because he knows what would happen if he runs.
  • Determinator: Ryotaro's a pushover, but when he wants something, no matter how much you beat him down, he'll keep getting up to get it.
  • Face–Heel Turn: Forced to do so by Yu-Ki in Final Countdown but is later rescued.
  • Finishing Move: Liner Form's Train Slash (Densha Giri), which has five variations, four of which depends on the DenKamen Sword's setting:
    • Momo-Sword Mode: DenKamen Slash note 
    • Ura-Rod Mode: DenKamen Attack note 
    • Kin-Ax Mode: DenKamen Chop note 
    • Ryu-Gun Mode: DenKamen Shot note 
    • Full Throttle Break: Activated by spinning the turntable one full circle. During the attack, DenLiners Gouka, Isurugi, Rekkou and Ikazuchi flank on different sides of Den-O.
  • Fragile Speedster: Liner Form.
  • Honor Before Reason: In an early episode, Ryotaro becomes angry with Momotaros for (unwittingly) aiding a robber. Later on he refuses to let Momo fight until he apologizes and promises never to let anything like it happen again. He does this in the middle of a battle where the Imagin is beating him senseless.
  • Identity Impersonator: During the final arc, while stranded in the past, Ryotaro impersonates himself in order to find out the secret of his family from his sister.
  • In the Style of...: In addition to singing in all five standard versions of Double-Action, he gains a solo, Rock 'n Roll theme called Real-Action about the same time he gains Liner Form.
  • Joke Character: Plat Formnote .
  • Locked Out of the Loop: The fact that he's a Singularity Point plays a major role in Sakurai and Airi's plans, which Ryotaro himself doesn't learn until the next-to-last episode, and only then by deceiving a past version of Airi.
  • Many Spirits Inside of One: In his Climax and Super Climax Forms.
  • Masculine Girl, Feminine Boy: Feminine Boy to Hana's Masculine Girl.
  • Meaningful Name: "Ryotaro" means "good boy".
  • The Nth Doctor: After Takeru Satoh left the cast following the third movie, Takuya Mizoguchi (who played 11-year-old Ryotaro in the first) took over the role in the fourth with a Hand Wave about how changes to the past do this sort of thing all the time.
  • Parental Abandonment: Ryotaro's parents died when he was young, leaving his sister and grandmother to raise him.
  • The Pollyanna: A rare male version.
  • Powers via Possession: How Ryotaro is able to access most of Den-O's forms.
  • Raised by Grandparents: As mentioned in Ore, Tanjou!
  • Ripple Effect-Proof Memory: One of the defining characteristics of a Singularity Point. However, a Plot Hole opened when it was revealed in the finale that Sakurai and Airi's plan erased his memory of their daughter in the past. It was one of Sakurai's cards that erased his memory, but he regained it, for the most part, upon meeting Yuto.
  • Running Gag: Ryotaros will always...
  • Sensitive Guy and Manly Man: Sensitive Guy to Yuto's Manly Man.
  • Shrinking Violet: Ryotaro during the beginning of the series was a cowardly type and usually shy.
  • Skunk Stripe: Whenever an Imagin possesses him, he gets a different color streak in his hair.
  • Super Mode: Liner Form, where he gains a special BFS that has the powers of ALL the Taros, and can even summon the Den Liner to aid in his own unique Finishing Move.
    • Played with in that stats reveal that it's actually weaker than other forms in some regards, and he's still a novice fighter in the form.
  • Swiss Army Weapon: DenKamen Sword; like the DenGasher, it can emulate whatever Den-O weapon the Liner Form is imitating.
  • This Loser Is You: Has elements of it, but gets better.
  • Time-Shifted Actor: Aside from Takeru Sato and Takuya Mizoguchi's meeting in the first movie, the ending of the third movie shows Kotaro arriving in his timeline, and meeting up with Ryotaro as an old man (who was only seen from the back).
  • Took a Level in Badass: After he achieves Liner Form, he comes over as much more serious and determined than at the start of the series.
  • You Gotta Have Blue Hair: Any possession by an Imagin changes his hairstyle and adds a touch of color. This even applies when possessed by the evil Ghost Imagin in Final Countdown, turning his hair entirely white.

Hana Sakurai/Kohana (portrayed by Yuriko Shiratori/Tamaki Matsumoto)

The mysterious young woman who drags Ryotaro into the battle with the Imagin, providing him with the Den-O Belt and DenLiner. Hana is the only survivor of a future timeline wiped out by the Imagin, saved only by the fact that she's a Singularity Point like Ryotaro. Because of this, she has a strong dedication to protecting the timeline and a fierce hatred for Imagin, a stance which gradually changes as she interacts with the Taros. She helps Ryotaro investigate the Imagin, and works to keep the Taros in line, usually berating (or Dope Punching) Momo for being violent or Ura for chasing skirt. As a new connection to Hana's destroyed time forms, she finds herself de-aged into a ten-year-old whom Ryotaro nicknames Kohana (literally "Little Hana") and tries to pass off as Hana's little sister to Muggles. Late in the series it's revealed that Hana herself is the key to the future timeline as the Junction Point between present and future, as well as Yuto and Airi's daughter and thus Ryotaro's niece.

  • Action Girl: In a case different from the role of most female leads in Kamen Rider, she actually accomplishes things throughout the show, and isn't even afraid of taking on numerous martial artists at once in a fight. It also helps that she has an unusually powerful punch for someone of her frame.

Naomi (portrayed by Rina Akiyama)

The DenLiner's waitress/stewardess, Naomi runs the dining car and serves coffee to the Den-O team. She's energetic and unflappable, sticking to her philosophy of only making coffee. She's great friends with the Imagin, often playing with Ryutaros; it was Naomi who named him in the first place. Despite appearing to be little more than a ditzy waitress, Naomi is a fixture of the DenLiner and has demonstrated resourcefulness and resolve when things look bad.

  • Big Damn Heroes: Rescues Kintaros and Urataros in the past, and brings them alongside Sieg to the present for the final battle.
  • Cordon Bleugh Chef: She puts salt, pepper, flour, and wasabi in her coffee. The only people who like it are the Imagin. However, this status only applies to her coffee; the food she makes is excellent, if sometimes a bit excessive in volume.
    • Oddly, during one episode where Naomi was taking care of Airi's shop, she took a taste of Airi's coffee and had the same reaction people other than the Taros have with her coffee. Kinda calls into question her tastes.
  • Genki Girl: Usually seen with lots of energy and a smile on her face.
  • In the Style of...: Double-Action Coffee Form, along with Airi = Light Pop.
  • Painted-On Pants: With arrows.
  • The Pollyanna: Hardly seen without her smile.
  • Tomboy and Girly Girl: Girly Girl to Hana's Tomboy.


The Owner (portrayed by Kenjiro Ishimaru)

The mysterious man who operates the DenLiner and works with Hana to protect the timeline. He occasionally imparts cryptic information to Ryotaro, but is primarily concerned with the safety of the DenLiner and its passengers, leaving the Imagin to Den-O. Mostly laid-back, he can be harsh towards those who break the train's rules, bother his passengers, or attempt to disrupt time. His "hobby" is eating piled foods (such as rice, flan, or pudding) with a flag on top, attempting to take as many bites as possible before the flag falls. Later in the series the cast meets the Station Master who runs the KingLiner and is the Owner's rival in the food-flag "game".

  • Berserk Button: Mess with the rules of the DenLiner and the normally mellow Owner might slap you with a Denial of Passage ticket.
  • Everyone Calls Him "Barkeep": The Owner and the Station Master have no names other than their job titles.
  • Identical Stranger: The Owner and the Station Master, obviously.
  • Inexplicably Awesome: He displays some strange supernatural abilities, such as destroying an electrically charged cell with a paper flag, having immunity to Ryuutaros' mind control and running so fast he can keep up with the Den-Liner! The character himself receives no backstory whatsoever.
  • Running Gag: Because of the above trope, characters who meet both the Owner and Station Master at the same time actually confuse them for twins.
  • Serious Business: Food Flags toppling over before he finishes his food.


Momotaros/Kamen Rider Den-O Sword Form (voiced by Toshihiko Seki; suit actor Seiji Takaiwa)

The first Imagin to possess Ryotaro, he resembles the red oni from the legend of Momotaro, and his abilities (including those as Den-O Sword Form) are drawn from the same story. Hot-Blooded and hot-headed, Momotaros is always spoiling for a fight whether with enemy Imagin or with whomever happens to tick him off at the moment. Initially annoyed when he realized he possessed a Singularity Point, the then-unnamed Imagin sided with Ryotaro when they were attacked by the Bat Imagin on the basis that if Ryotaro died, so did he. After the battle, Ryotaro gave the red oni-esque Imagin the name "Momotaros" after the legend of Momotaro the Peach Boy. While a brash Boisterous Bruiser might seem at odds with Ryotaro's normal personality, it's his eccentricies like posing, pre-battle speeches and calling his attacks that makes Den-O resemble more traditional Kamen Riders. Despite his rough attitude, Momotaros is fiercely loyal to his teammates, and seeks to improve Ryotaro by toughening him up and improving his "bad taste".

  • Anime Hair: A side effect on people possessed by him.
  • BFS: MomoSword.
  • Big Brother Instinct: Eventually develops one for Ryotaro as well as the other Taros. He even takes it personally when he thought Ura was Evil All Along (he wasn't).
  • Blood Knight: Has elements of it at the start, before developing into a... Boisterous Bruiser.
  • Butt-Monkey: Ryotaro's luck seems to have rubbed off on him. This is exemplified in the fourth movie; literally, even.
  • Brain Bleach: His reaction to learning that Deneb used Urataros' bath water in the broth that Deneb was serving to the crew. Can't really blame Momo. Still, it was just a joke by Naomi.
  • Calling Your Attacks: "Hissatsu! My finishing attack...Part (number/____Version)!"
  • Catch-Phrase:
    • "Ore, sanjou!" English 
    • "From start to finish, I'm always at a climax!" Japanese 
    • "Let's go, go, go!!" Japanese 
  • Character Tics: Tends to do bombastic poses, most famously the "Ore, sanjou!" pose which consist of pointing at himself on the Ore, then standing with his arms spread at sanjou!. Also, Blade on the shoulder when he's Den-O.
  • Cool Sword: DenGasher Sword Mode.
  • Critical Research Failure: In-universe, Played for Laughs.
    Momo: It's Mt. Fuji!
    Hana: What are you saying? That's not Mt. Fuji, that's a pyramid!
  • Deuteragonist: Being the first Imagin and being the exact opposite of the protagonist, he gets the most focus.
  • Fish out of Temporal Water: Twice in the Cho Den-O series:
    • In Onigashima Battleship, while the other Taros were also stranded (in the 30's-40's), they manage to stay together, but Momo, all alone, gets stuck in the distant past, in the very period where the Oni were waging their war against the humans.
    • In Episode Red, he gets thrown overboard when the DenLiner was out of control, getting stranded four months before the events of the movie.
  • Four Is Death: Lampshades it when Ryotaro points out that he skipped over number 4 in his attack-calling; Momo claims that he did it because it's cool to skip four, then proceeds to count to ten, jumping from three to five.
  • Finishing Move:
    • Extreme Slash
    • DenRider Kick: A Hurricane Kick. First used in the fourth movie.
  • Literal Asskicking: He's fond of doing this to his opponents, whether it involves his actual feet or even his sword.
  • The Nicknamer: Even moreso than the rest of the cast. He calls Urataros "Kame" (Turtle), Kintaros "Kuma" (Bear), Ryutaros "Kozo" (Brat) or "Hanatare Kozo" (Snot-Nosed Brat), Hana "Hanakuso Onna" (Nosy Woman), Sieg "Chicken Wings", Deneb "Odebu" (Tubby) and Teddy "Tendon". He also has a habit of tacking "Yaro" (a rude version of "you", usually rendered as "Jerk" or "Bastard") onto the end of most of his nicknames; in fact, he only refers to enemy Imagin by their species and with "Yaro" tacked on the end, as in "Mogura Yaro" (Mole Jerk)
  • Red Eyes, Take Warning: People possessed by Imagin have their eyes change color to match; Momo, obviously, makes them go red.
  • Red Oni, Blue Oni: The red to Urataros' blue.
  • Rule of Cool: What Momo usually tries to go by.
  • Running Gag: Being mistaken for an Oni. It doesn't help that he was designed that way.
  • Scarf of Asskicking: People possessed by Momo, especially in his Decade appearances, gain one in addition to red eyes and a spiky hair with a single red streak.
  • Small Name, Big Ego: Played for laughs in the Imagin Anime spin-offs, going so far as to try to make himself Toei's mascot, then throwing a fit when he spots the HeartCatch Pretty Cure! poster nearby.
  • Spotlight-Stealing Squad: After the Yellow movie, Ryotaro wasn't seen in KR ever again. For every future appearance of Den-O, Momotaros took the lead as the main man.
  • Super Drowning Skills: He can't swim.
  • Trademark Favorite Food: Pudding. He even starts up a pudding shop in Imagin Anime.
  • Translation Convention: Momo's catchphrase "Ore, sanjou!" is a rough way of saying "I have arrived!" (fitting for the Train-themed rider), "Here I am!", or "Here I come!", but most fans just leave it in Japanese because there's no translation that sounds quite right.


Urataros/Kamen Rider Den-O Rod Form (voiced by Koji Yusa; suit actor Eitoku)

The second Imagin to possess Ryotaro, his appearance and abilities (both as himself and Den-O Rod Form) come from Ryotaro's mental image of the mythical Urashima Taro. In stark contrast to the fight-happy Momotaros, Urataros is laid-back, non-confrontational, and clever. A Consummate Liar, Ura can talk anyone into just about anything; since he's an enthusiastic skirt-chaser, he can often be found using his talent to charm the socks off of any cute girls he meets while possessing Ryotaro. He was aware that Ryotaro was a Singularity Point, and willingly possessed him in the hopes of extending his lifespan and meeting women. Because of his non-confrontational nature, Rod Form is the least used of Den-O's forms, but Ura's skills come in handy when they need to gather information about a rogue Imagin - that is, provided Hana can keep his mind on the task at hand...

  • Consummate Liar: In addition to his own skills, he claims his goal is to teach Ryotaro to be a better liar.
  • Double Weapon: UrataRod.
  • Fake Defector: Pulls this off in the final story arc. He pulls it off really well, too, thanks to his nature.
  • Finishing Move: Solid Attack, followed by DenRider Kick.
  • Guile Hero: A liar and a trickster, but still has a good heart.
  • In the Style of...: Double-Action Rod Form and Climax Jump Rod Form = Ska.
  • Japanese Pronouns: "Boku".
  • The Nicknamer: Calls Momotaros "Sempai" (because Momo insisted) and refers to most people either affectionately ("Kin-chan", "Naomi-chan") unless they've earned his respect ("Hana-san", "Airi-san"). He calls Yuto "Boku-chan" (a very childish way of saying "me") as a reference to the young man's selfish nature.
  • Red Oni, Blue Oni: The blue to Momotaros' red.
  • Sexy Man, Instant Harem: He was able to woo all of the nurses while in the hospital, and him walking into the carnival gets all the girls to squeal and rush toward him.
  • Spit Take: Gave a particularly infamous one when Ryotaro decided to have another Imagin join the team. It's particularly of note because his character suit doesn't have an articulate jaw.
  • Stoic Spectacles: People possessed by him gain these in addition to the blue eyes and streak in their hair.

Kintaros/Kamen Rider Den-O Ax Form (voiced by Masaki Terasoma; suit actor Jiro Okamoto)

The third Imagin to possess Ryotaro, inspired by the legend of Kintaro, which also extends to Den-O Ax Form. Initially contracted to a sickly martial artist named Masaru Honjou, whose wish to achieve the "ultimate karate". Much to Ryotaro and Hana's surprise, the Imagin actually stuck to the contract, training Honjou's body while in control and showing no interest in disrupting time. Ryotaro recognizes his nobility after he's mortally wounded protecting Honjou from the Rhino Imagin and offers a contract in order to save his life. The strong, silent Kintaros usually sleeps the day away until someone presses his button by saying the word "Nakeru" (Japanese for "cry")...or anything even remotely sounding like "Nakeru", which causes him to possess Ryotaro instantly, unceremoniously booting out anyone already possessing him. Out of all the Taros, Kin is the nicest and friendliest, showing an uncharacteristic amount of real emotion for an Imagin.

  • Benevolent Genie: Unlike near every other Imagin in the series, Kintaros not only upheld the spirit of Honjou's wish, as opposed to the letter, he only completed the contract early in order to go back in time and protect him from the Rhino Imagin.
  • Berserk Button: DON'T EVER make a girl cry.
  • Boisterous Bruiser: Not violent like Momo, but still loves a good fight.
  • Calling Your Attacks: In an odd variation, he only says the name of his Finishing Move after performing it, which Ryotaro specifically notes the first time he does it.
  • Catch-Phrase: "My strength has made you cry. Wipe your tears with this!" Japanese  Sometimes shortened to just "My strength has made you cry!" or just "You cried!" Japanese 
  • Character Tics: Pops his neck by pushing a hand (or sometimes a finger) against his chin. The Badass Arm-Fold is his default pose.
  • Cherry Blossoms: Parodied, as occasionally the transformation into Ax Form will be accompanied by fluttering...tissues. "Wipe your tears", indeed.
  • The Ditz: You have to wonder about the sort of person who mistakes Sumo for Karate and doesn't realize what he's done until children explain it to him.
  • Does Not Know His Own Strength: He isn't built for normal human behavior. Coupled with Ryotaro's already bad luck, and accidental collateral damage is common.
  • Everyone Has Standards: In his introductory episode, Kintaros is willing to fight anyone who stands in his way, but he will not cause collateral damage or hurt women. Plus, he was willing to catch criminals for the police in the following episode.
  • Finishing Move: Dynamic Chop.
  • Hammer Space: He can pull tissues out of thin air, apparently.
  • Heavy Sleeper: And narcoleptic to boot; since he's a bear, this presumably represents hibernation. The only way to wake him up is by activating his Berserk Button.
  • Honor Before Reason: Demonstrated in his A Day in the Limelight two-parter where he puts aside fighting the Monster of the Week in order to prove to a young girl that she's wrong in thinking her father hates her, and he's willing to be kicked off the DenLiner in order to prove it. Thankfully, he's right about the father, and the changes Kintaros caused mean the Imagin never became a threat, so Owner let him stay.
  • Implausible Deniability: When Owner once said that Kintaros' snoring is a problem, Kintaros wakes up just to deny it.
  • In the Style of...: Double-Action Ax Form and Climax Jump Ax Form = Enka.
  • Japanese Pronouns: "Ore".
  • Kansai Regional Accent: He speaks in the Kansai dialect, given that his actor Masaki Terasoma grew up in Osaka.
  • The Klutz: Seen moreso when he's possessing Honjo and Ryotaro than in his natural form.
  • Manly Tears: His catchphrase is "You'll cry!", and he tends to shed said tears whenever Ryotaro (or anyone else, for that matter) displays any kind of notable strength or determination.
  • The Nicknamer: Calls Momotaros "Momonoji" (Peach), sometimes mispronouncing it as "Momonga" (Flying Squirrel) or "Momohiki" (Long Underwear); calls Urataros "Kamenoji" (Turtle). Note that the -oji suffix actually refers to them as "sir" in the sense of an old man in the same way that Urataros refers to Momotaros as "-sempai".
  • Noble Demon: The only one of the Taros to not start off as a Villain Protagonist.
  • Noodle Incident: Destroying the DenLiner's bathtub, causing Urataros to be swept away. It actually happened in-series (mentioned in passing as a background discussion), but we never see the details on-screen.
  • To Be a Master: His desire to be the strongest warrior presumably comes from his original contractor Honjo.
  • Weapon of Choice: The Den-Gasher's Axe Mode.

Ryutaros/Kamen Rider Den-O Gun Form (voiced by Kenichi Suzumura; suit actor Toshihiro Ogura)

The fourth Imagin to possess Ryotaro and the last member of the "Taros", making up the core team. Appearing last, he was actually the second to possess Ryotaro, as revealed in flashbacks to Urataros' debut episode, and subsequently buried himself deep in Ryotaro's psyche, only being revealed during a hypnosis session instigated by Miura. At first he wants to kill Ryotaro, having been given an unrevokable Liner Pass and told that he can take over the DenLiner if he destroys Den-O. However, he falls in love with Airi and abandons his mission when the others point out that killing her brother would upset her. Childish and willful, Ryuta is the strongest of the Taros, and usually can't be "booted" from Ryotaro's body unless Momo, Ura, and Kin work together. His brash attitude causes a lot of problems normally and in battle as Gun Form, causing lots of collateral damage. He loves animals and dancing, and has the power to make people dance with him by snapping his fingers. His crush on Airi and bad advice from Kintaros caused him to develop a jealous hatred towards Yuto, which causes even more problems.

  • Animal Motifs: Dragon (?)
  • BFG: Ryuvolver.
  • Break the Cutie: Near the end of the series, Ryutaros gets confronted by Kai who nearly made Ryuutaros destroy DenLiner, and at the same time, lose his affection for Airi when Airi saw Ryutaros possesed Ryotaro and knew that he wasn't her brother. Made all the worse because Ryutaros was trying to give Airi a picture he made of her and couldn't. Poor guy.
  • Catch-Phrase: "Mind if I (something)?", most commonly "beat you" or "end it", followed by "Can't hear the answer!" Japanese 
  • Character Tics: Spinning around during his Catch-Phrase, followed by Giving Someone the Pointer Finger.
  • Cheshire Cat Grin: If he possessed Ryotaro and he holds a grin, RUN. If you don't, then there is a chance that he is going to chase you down with his dance posse and will not stop until he catches you!
  • Crowd Song: A rare justified version. Sometimes he uses dances to chase people down.
  • Cuteness Proximity: He loves cute little animals, sometimes possessing Ryotaro just to pick up an animal and cuddle them.
  • Dance Battler: When fighting, he moves around as if dancing.
  • Destructive Savior: He means well, but let's just say his aim is terrible.
  • Dragon Rider: When Ryuta drives the DenLiner, he controls it from on top of the Ikazuchi (Car #7)'s dragon head, rather than the cockpit in Gouka (Car #1) as the other three Taros do.
  • Finishing Move: Wild Shot.
  • Friend to All Living Things: He loves all types of animals, particularly kittens, puppies and birds.
  • Funny Background Event: He's pretty much a walking one. No matter how serious the scene happening in the foreground is, if Ryoutaros is around, more often than not he's dancing around in the background or doing something childish like drawing pictures. Naomi is known to join him on occasion.
  • Gangsta Style: Likes to wield his gun sideways in Gun Form.
  • Glass Cannon: Was originally the Lightning Bruiser before Wing Form was given that role.
  • The Gunslinger: Although if in dire situations, he can resort to Pistol-Whipping.
  • Handguns: DenGasher Gun Mode.
  • Iconic Item: His Bubble Gun. Becomes a Chekhov's Gun when it's one of the items that Kintaros gives to Ryotaro to complete their contract.
  • I'm Taking Her Home with Me!: Ryuta loves animals, and has a habit of bringing them back to the DenLiner. This is actually how the cast is introduced to Sieg.
  • In the Style of...: Double-Action Gun Form and Climax Jump Gun Form = Hip-Hop. Climax Jump Hip-Hop Version. In addition, he also gets to rap in several songs like Climax Jump DenLiner Form.
  • Japanese Pronouns: "Boku".
  • Laser-Guided Tykebomb: Kai told him to kill Ryotaro and gain control of the DenLiner. Ryutaros decided not to do so due to his love for Airi.
  • Love Redeems: Decides not to kill Ryotaro after realizing that his death would make Airi cry.
  • Macross Missile Massacre: Climax Form's Boistous Shot.
  • Murder the Hypotenuse: His response to learning that Airi loves Sakurai is to go after Yuto and try to kill him. It doesn't help that Kintaros advised him how to win Airi's heart.
  • Nice Hat: Whenever he's possessing someone to go along with the wavy bangs and purple streak in the hair.
  • The Nicknamer: Calls Urataros "Kame-chan" and Kintaros "Kuma-chan". Since Momotaros isn't based on an animal, Ryuta just calls him "Momotaros" without Honorifics, which annoys Momo.
  • Pet the Dog:
    • He confronted the Dance Posse and asked them if they were the reason that the animals being fed in the park got frightened.
    • He realizes that the Owl Imagin's rampage in the past will cause the puppy cared for by its contractor to die, and resolves to fight the Imagin full-force.
  • Psychopathic Manchild: Whenever he possesses Ryotaro, he somehow holds some kind of glee in chasing people down for no apparent reason. And for a while, he thought the best way to win Airi's heart was to get rid of Yuto (see Murder the Hypotenuse above) and this was shown most prominently in a picture he drew (which depicts Den-O Gun Form blowing a giant bloody hole through Zeronos' chest). The biggest offender would be in Climax Deka, where he starts whipping out the handcuffs to any person who just looks like he'd be part in an Evil Organization.

Sieg/Kamen Rider Den-O Wing Form (voiced by Shinichiro Miki; suit actor Naoki Nagase)

An arrogant swan Imagin, inspired by the story of Swan Lake and it's male protagoist, Prince Siegfried in specific. He possessed a rich heiress, but because she was pregnant at the time, the contract passed to her unborn son. Sieg first came into being following the child's birth, referring to mother and child as his family. He was brought to the DenLiner crew's attention when Ryutaros brought him onto the train. His arrogant demeanor rubbed everyone the wrong way until Hana punched some sense into him, at which point he began calling her "Princess" and started gradually referring to the others as family rather than servants. He allows Den-O to assume the exceptionally powerful Wing Form, but because his contract was formed with a child, whose memory isn't as strong as an adult's, he begins "fading". Ryotaro discovers a "loophole" in that Sieg's contract with the heiress was still active, allowing him to travel to the past and exist peacefully; despite this development, he shows up in critical moments such as the series finale and the movies.

  • Aloof Ally: Inverted; he's actually willing to lend a hand to the DenLiner crew whenever and however he can, but most of the time the Taros (especially Momo) don't want anything to do with him.
  • Animal Motifs: Swan.
  • An Axe to Grind: DenGasher Handaxe Mode (made from the Axe and Gun parts).
  • Butt-Monkey: Perhaps as a result of audience reaction towards him. In later appearances, Sieg is treated with comedic levels of contempt by the other Taros, probably due to his acerbic personality.
  • Camp Straight: Obsessed with "beauty" but has feelings for Hana.
  • Catch-Phrase: "Advent! To the top!" Japanese 
  • Cultured Badass: He's based on a prince, and his form is the most powerful of Den-O's basic forms.
  • Demonic Possession: Though hardly unique to him, as an Imagin, Sieg's possessions are exceptionally powerful. Whether it's from his being born in the present or by sheer force of will, Sieg is near impossible to remove from Ryotaro once he has possessed him. Even when the other Taros are unable to possess Ryotaro due to amnesia, Sieg was able to do it just fine.
  • Deus Exit Machina: Wing Form is Den-O's most powerful basic form, and writers have made sure that his use was a rarity. The situation is inverted in Ore, Tanjou! where Sieg is the only Imagin available for a good portion of the movie (Ura and Kin were held captive, Ryuta was temporarily convinced by Gaoh to his side, and Momo couldn't synchronize with Ryotaro because the latter has amnesia). Played straight again later, where Sieg is the only Den-O that isn't present in the movie's climax, although no explanation was given for that since Yuuto could have just kidnapped a Sieg-possessed Ryotaro for the battle except perhaps being injured after getting hit by Gaoh's Tyrant Clash as Den-O.
  • Dual Wielding: Uses a weapon each composed of two pieces of the DenGasher.
  • Everything's Better with Princesses: At least, that's what he thinks with Hana, always calling her "Hime-san" (Princess) whenever she appear after she slapped him in the face.
  • Finishing Move: Royal Smash.
  • The Friend Nobody Likes: Most of the time, everyone sans Ryutaros seems reluctant whenever he appears.
  • Incredible Shrinking Man: Has the power to make people shrink to action figure-size by saying "Bow your head!" Japanese  The Imagin Anime gives him "Super Bow Your Head", which shrinks the whole world.
  • In the Style of...: Double-Action Wing Form = Arabic Pop
  • It's All About Me: "The world revolves for my sake."Japanese 
  • Japanese Pronouns: "Watashi".
  • Jerk with a Heart of Gold: Despite his superority complex and belief the world revolves just for him, he's actually a really good person at heart. The problem is just that the other Imagin don't want anything to do with him.
  • Nerf: An in-universe one, his power and memory is weakened considerably due to his contract holder being a child. Taking into account how strong he still is, he would be unbelievably powerful if properly contracted to an adult.
  • Power Gives You Wings: Especially in Super Climax Form.
  • Precision-Guided Boomerang: DenGasher Boomerang Mode (made from the Sword and Rod parts).
  • Put on a Bus: In series, this is justified due to how weak the imagination of the person he is contracted to is - however, he does return for the finale. In-franchise, his last appearance was in Episode Blue of the Chou Den-O trilogy. He hasn't been seen since - not even in Let's Go Kamen Riders.
  • Spell My Name with an "S": Some databooks list his name as Zieg.
  • Stealth Hi/Bye: In Final Countdown, he disappears during the Imagins' attempt to protect the Japanese village from Shiro's mercenaries, but later reappears for the climax much to everyone's surprise.
  • The Thing That Would Not Leave: For the Hikari Studio. Only Eijiro wants him around, and it's for taking pictures anyway.
  • True Companions: Constantly refers to the other Imagin as "family", much to Momo's chagrin.

    Civilians 

Airi Nogami (portrayed by Wakana Matsumoto)

Ryotaro's older sister and the owner of the Milk Dipper library cafe. She was forced to help raise Ryotaro after the death of their parents and thus often seems wise beyond her years. She's also very close to Ryotaro, worrying about his well-being and trying to help out with health drinks and herbal concoctions. The beautiful Airi enjoys good business mostly thanks to the horde of lovestruck men who pack the shop from opening to closing. For her part, Airi remains completely oblivious, her only passions seeming to be stargazing and brewing the perfect cup of coffee. One year prior to the series' start, Airi's fiance Yuto Sakurai vanished a month before the wedding; initially Ryotaro thought she hid her pain behind a smile, but to his great concern she seems to have completely forgotten about Sakurai, not even remembering why she has his beloved telescope in the shop (but still gazing at it fondly) and not realizing that the pocketwatch he gave her rests beneath it. Late in the series, Ryotaro discovers that Airi is in fact perfectly aware of just about everything that's happened up to that point, including Ryotaro being Den-O, and in fact helped orchestrate the whole thing along with Sakurai in order to protect the Junction Point from the Imagin.

  • Beware the Nice Ones: In one episode, Ryotaro offends Airi by calling in a hazmat team to dispose of one of her "healthy" concoctions; her response is to throw things at him, culminating in his own bicycle.
  • Unwanted Harem: Not unwanted so much as completely unnoticed.
  • Yamato Nadeshiko: Pretty, caring, an excellent cook, and completely unflappable. Upon being told that Ryotaro was being held hostage by an armed robber, her immediate reaction was to go back to preparing coffee. The wisdom part is thus:She's been in on her fiancée's plan from the beginning, and allowed her own memories to be altered in order to protect the Junction Point, their future daughter Hana. And she's known from the start that "Ryo-chan" was Den-O, and that his friend Yuuto is the time-displaced teenage version of her fiancée.

Seigi Ozaki (portrayed by Akira Nagata)

One of the Milk Dipper regulars, Ozaki is a journalist for a Kasutori Magazine who's always on the lookout for a new scoop. He's also a major flirt, chasing women since a crush on his first-grade teacher and using his job to try and pick up chicks. However, he's most devoted to chasing Airi, trying to impress her with his connections while sparring with Miura. He's friendly towards Ryotaro, styling himself as the younger boy's future brother-in-law and sometimes sharing stories that, unbeknownst to him, reveal information about Imagin attacks.


Issē Miura (portrayed by Ryo Ueno)

A self-proclaimed "super counselor" and Milk Dipper regular who feuds with Ozaki for Airi's affection, but is more introverted. Ozaki often tries to undermine Miura by making his interest in the occult look like superstitious nonsense, while Miura counters by pointing out Ozaki's wandering eye. He's also nice towards Ryotaro, and shows a good deal of concern for his well-being. After witnessing a battle between Momo and Ura for control of Ryotaro's body, Miura becomes convinced that Ryotaro is possessed and tries to help exorcise him, only to accidentally reveal the existence of Ryutaros.

  • Ignored Expert: In regards to the Imagin, at least until Airi and Ozaki meet them in Climax Deka.

    ZeroLiner Crew 

Yuto Sakurai/Kamen Rider Zeronos

Because of the time-traveling nature of Kamen Rider Den-O, two versions of Yuto Sakurai exist as independent and distinct characters. Here, as in most media, they will be distinguished by their names, "Yuto" referring to the younger version and "Sakurai" to the older.

Yuto (portrayed by Yuichi Nakamura)

The teenaged version of Yuto Sakurai, as well as the warrior Kamen Rider Zeronos and the partner of the Imagin Deneb. Yuto initially appears after Ryotaro gets too close to Sakurai, warning the soft-hearted young man not to interfere, believing that protecting the timestream is different from protecting individuals, unlike Ryotaro. The brash, hot-tempered Yuto stands greatly at odds with Ryotaro's memories of a gentle, kindly, brotherly Yuto Sakurai, but according to Owner, the two are indeed one and the same. He also acts childish at times, preferring his coffee overloaded with sugar, despising shiitake, and enacting comedic violence upon Deneb whenever the Imagin annoys him. Contact with Ryotaro and the DenLiner crew tempers Yuto's harsh personality as well as maturing him. Ryotaro (and the audience) eventually learn that the Zeronos powers operate by "burning" the memories people have for Sakurai, explaining why nobody except Ryotaro remembers him. After using up all the original Zeronos Cards, Sakurai offers him more, along with a new card that turns Altair Form into the Super Mode Zero Form, which is fueled by memories of Yuto rather than Sakurai. The disappearance of Sakurai at the end of the series leaves Yuto with a new future to discover, which he gladly undertakes alongside Deneb.

  • Anger Born of Worry: In the finale, upon seeing Deneb alive again, Yuuto was about to seemingly attack him again, only to fall into tears in Deneb's arms.
  • Boke and Tsukkomi Routine: Tsukkomi to Deneb's Boke.
  • Brought to You by the Letter "S": (A)ltair and (V)ega, which is visible on both their corresponding Zeronos cards, the ZeroLiner's cars, and their Finishing Moves.
  • Catch-Phrase: "Let me say this to start: I'm pr-e-tty strong!" Japanese . On a couple of occasions, Yuto replaces the second part with "I'm pretty ticked off!"
  • Catchphrase Spouting Duo: Oftentimes, with Deneb.
  • Character Tics: Giving Someone the Pointer Finger ("Let me say this to start! I'm pr-e-tty...") followed by the Bicep-Polishing Gesture ("...Strong!").
  • Deadly Upgrade: The Zero Form cards.
  • Deus Exit Machina: Hospitalized, and therefore absent, for a good portion of Final Countdown after Taking the Bullet for Kohana, but reappears just in time for the climax. In Onigashima Battleship, the alteration of the timeline causes him to be erased from reality, again.
  • Did Not Get the Girl: At least not yet anyway. Much of the Episode Red movie dealt with the fact that Airi can't love the current Yuto the same way she did Sakurai (although the existence of Hana in a younger form implies that the two will eventually get together; presumably once Yuto matures into someone more like Sakurai).
  • Does Not Like Spam: Shiitake Mushrooms.
  • Finishing Move:
    • ZeroGasher: While Zeronos is in Altair Form, both of this weapon's mode's finishers take on the form of a green A.
      • Bowgun Mode: Grand Strike
      • Sabre Mode: Splendid End
    • Denebick Buster: Buster Nova
  • Fuel Meter of Power: He has a very limited suppy of henshin cards and has to make his transformations count.
  • Heroic Willpower: While Ryotaro can't manifest any decent Den-O forms by himself (until Liner Form), Yuto's stronger will allows him to assume Zeronos Altair Form without the aid of an Imagin.
  • Holding Back the Phlebotinum: With good reason.
  • In the Style of...: Action-Zero = Rock. 2010 Version = Soft Piano.
  • Jack-of-All-Stats: Altair Form, one of the forms Yuto can assume.
  • Jerkass Façade: Comes with the revelation about the Zeronos Cards, explaining that Yuto acts rude to keep people distant.
  • Lightning Bruiser: Zero Form, one of the forms Yuto can assume.
  • Ma'am Shock: Delivers one to Mach during the events of Super Hero Taisen GP.
    "Don't call me Old Man!"

Sakurai (portrayed by Tomonobu Okano)

Airi's fiance and Ryotaro's future brother-in-law, Sakurai was a gentle, kind-hearted man with a passion for astronomy he shared with Airi. The two were very much in love, and Sakurai treated Ryotaro like the little brother he never had; thus, Ryotaro's surprise when Sakurai disappeared just before the wedding is understandable, as is his confusion at the fact that nobody seems to remember his existence. Several times in the early part of the series, a cloaked man appears watching Den-O's battles in the past and checking a pocketwatch; by accident, Ryotaro bumps into the man and recognizes him as Sakurai. He attempts to track down the man, only to be warned off by Yuto. Eventually Ryotaro learns that Sakurai discovered the ZeroLiner and learned of the Imagin. In order to protect his and Airi's daughter, the Junction Point, Sakurai engineered his own disappearance before handing off the Zeronos Belt, ZeroLiner, and his partner Deneb to his teenaged self, while he used himself as bait for the Imagin in the past. Late in the series, Sakurai appears and becomes Zeronos Altair Form, fighting alongside Ryotaro and Yuto in one battle. As Yuto uses the last of the Zeronos Cards, Sakurai vanishes from the timeline, though Airi remains confident that he'll return some day.

  • Big Damn Heroes: When Den-O and Zeronos were having trouble with The Dragon, Sakurai himself steps up to help them in battle, assuming Altair Form.
  • The Plan: Most of the show's plot is predicated on a plan by Sakurai and Airi to protect their daughter Hana from the Imagin.
  • Star-Crossed Lovers: With Airi, as referenced by Zeronos' theme (see Yuto's theme).
  • What the Hell, Hero?: Deneb tells off Sakurai for making Yuto use the Zeronos cards, even culminating in Deneb throwing Sakurai out of the ZeroLiner.

Deneb/Kamen Rider Zeronos (and New Den-O) Vega Form (voiced by Hochu Otsuka; suit actor Yoshifumi Oshikawa)

Yuto Sakurai's Imagin partner, inspired by the legend of Benkei and allowing Yuto to transform Zeronos into Vega Form. Deneb is kind-hearted but somewhat on the thick side, his polite friendliness contrasting greatly with Yuto's loud, rude attitude. He often tries to better Yuto, encouraging him to be nicer or to work alongside Ryotaro as an ally rather than viewing the DenLiner team as a hindrance. Occasionally Deneb will even possess Yuto and run around being friendly, doing good deeds, and passing out Deneb Candy in order to win friends for the young man, but this invariably results in a beating from Yuto once he regains control. Deneb is later revealed to be contracted to Sakurai, having joined the man after seeing his selfless battle against the Imagin, and their contract retroactively applying to Yuto as well. Since the Zeronos Cards erase peoples' memories of Yuto, Deneb tries to make friends for him in order to remove the burden of isolation. When Kai manages to kill Yuto in the past, this causes a timeline alteration that results in Deneb being contracted to Ryotaro, but this is eventually undone and things return to normal.

  • Apologises a Lot: One of the humblest Imagins in existence.
  • Arm Cannon: Type 1; his hands can fire bullets from the fingers.
  • Badass Cape: Vega Form.
  • Battle Butler: Does many things butlers do (shopping for food, cooking for Yuto, cleaning the ZeroLiner), has a very humble attitude, and assists Yuto in battle.
  • Benevolent Genie: In stark contrast to the other Imagin, Deneb outright defected from the Imagin cause and joined Sakurai under his own free will. Even the Taros required a bit of persuasion before they joined Ryotaro's side. What wish he granted Sakurai was never revealed, although by Onigashima Battleship he was able to possess Kotaro, so we can assume it was completed at some point.
  • Beware the Silly Ones: Despite being Yuto's ditzy comedic foil and the nicest guy in the series, his few fights as Zeronos and New Den-O Vega Form show he's actually much better at fighting than Yuuto (who's not bad himself).
  • BFS: ZeroGasher Sabre Mode.
  • Blade on a Stick: New DenGasher Naginata Mode (New Den-O Vega Form, when he possesses Kotaro in Onigashima Battleship).
  • Boke and Tsukkomi Routine: Boke to Yuto's Tsukkomi.
  • Catch-Phrase: Usually begins with Yuto's "Let me say this to start!" Japanese , only to mess it up with an honest fact that bewilders everyone around him; he uses "The face on my chest is just for show" Japanese  a couple of times. He also says "Take care of Yuto!"Japanese  both in conjunction with the first phrase and on its own.
  • Chunky Updraft: When transforming into Vega Form.
  • Demonic Possession: Although as an Imagin he's capable of it, it's rather notable in that Deneb refrains from possessing others outside of Yuto, even when it's established he can. Even when he possesses Kotaro he apologies beforehand.
  • Empathic Weapon: Transforms into the Denebick Buster whenever Zeronos assumes Zero Form, and can still talk to Yuto.
  • Finishing Move
    • ZeroGasher: While Zeronos is in Vega Form, both of this weapon's mode's finishers take on the form of a yellow V.
      • Bowgun Mode: Grand Strike
      • Sabre Mode: Splendid End
    • New DenGasher Naginata Mode: Brandish Dive
  • The Heart: Has many attempts to appeal, sometimes fail hilariously.

    The Imagin 

Kai (portrayed by Hideo Ishiguro)

  • Big Bad: Not revealed until in the middle of the series.
  • Catch-Phrase: "I have the face for it, don't I?" Japanese 
  • Fate Worse Than Death: When the Death Imagin is destroyed in the final battle, it takes his remaining memories with it. Despite being a Singularity Point, he'd destroyed so many of his past selves that he's completely erased from time due to this.
  • Faux Affably Evil: His manner of speech and actions are normally realitively unvillainous, which serves to make him far more creepy as a result. Note, he keeps this even when letting loose an entire army of Imagin on the city and preparing to open a time rift to erase an entire area and everyone in it from time.
  • Giggling Villain: Frequently seen with a creepy grin on his face and indulge himself in maniacal laughs.
  • The Man Behind the Man: Is the driving force behind the Imagin but doesn't appear in person until close to the end.
  • Psychopathic Manchild: He acts rather childish most of the time. Despite this, he's completely insane and willing to erase entire areas from time without any regard for life.
  • Time Master: Unlike others, he's able to travel through time without a Time Train. He's also able to tear open a hole in time and let loose an energy burst capable of erasing everything and everyone in the blast zone except himself from time.
  • That Makes Me Feel Angry: Does this a lot, and usually follows it up with his Catch-Phrase above, asking other characters if his face shows that emotion. It usually doesn't.
  • Villainous Breakdown: Gets progressively more insane and unstable as the series goes on. But after discovering for that Sakurai isn't the Junction Point as he previously believed, he snaps. He tears apart the black calendar he'd been using to plan his attacks, gives all his remaining Imagin physical form, channels everything he's got left into the Death Imagin for an all-out attack on Tokyo. He then proceeds to try and completely erase the entire area from time despite his army still being present.
  • Well-Intentioned Extremist: He's doing all of this for the sake of the Imagins' existence.
  • You Have Failed Me: Pulls this on Ryutaros after the latter couldn't bring himself to kill Ryotaro. There's a good reason Ryutaros is so scared of him.

Imagin

The series' Monster of the Week creatures, Imagin are time-traveling spirits from a destroyed alternate future, with the goal of changing the past to bring their future back into existence. Initially they manifest as golden balls of light, but upon possessing a human victim (in a burst of energy and sand) they take a form from that person's imagination, drawing upon their mental image of various stories, legends, or folk tales. Once possessing a victim, Imagin offer them a "wish", twisting that person's desires to destructive ends. Once the wish is granted (by whatever loose definition the Imagin is using), a portal opens to the past via a particularly strong memory of victim's. From there the Imagin goes back in time and runs rampant in an attempt to alter the timeline. Upon defeat, particularly poweful Imagin will revive as giant monsters called "Gigandeaths". The Imagin initially seem independent of one another and unorganized, but the appearance of Kai reveals the truth. Urataros later explains to Ryotaro and Hana that all Imagin hear Kai's orders in their heads, but it's up to them whether they obey or not. Though Kai's death also destroys most of the Imagin, the Taros, Sieg, and Deneb hang on thanks to the bonds of friendship formed with Ryotaro and Yuto, while several antagonistic Imagin remain through unknown reasons and menace the crew in the various sequel movies).

  • Animal Motifs: As part of their fables and fairy tales theme designs.
  • Be Careful What You Wish For: Most Imagin operate like this; in an early episode, the Crow Imagin interprets its victim's wish to forget her ex-fiance by destroying anything playing "Spring" from the Four Seasons Concerto, since she still owned a pendant he gave her that played the song.
  • Catch-Phrase: "Say your wish. I will grant any wish." note 
  • Deal with the Devil: One the user is compelled to give, despite a monster suddenly appearing before them. You're hard pressed to find anyone who willingly made a deal with an Imagin.
  • Demonic Possession: They are capable of possessing their hosts beyond the initial time they take to gain a physical form, but they usually don't indulge in it.
  • Dragon-in-Chief: Both the Albinoleo and the Death Imagin.
    • Rather than bring Kai back, they've had the Leo Imagin stand in to represent the Imagin any time the Kamen Rider evil organizations are gathered, like in Let's Go Kamen Riders.
  • Elite Mook: the New Molech Imagin, which always come up in large numbers.
  • If It Swims, It Flies: Some Hades Gigandeath have demonstrated this ability.
  • Jackass Genie: A few, particularly the Jellyfish Imagin, which twisted the victim's wish to find his late girlfriend's time capsule into meaning any old time capsule, and mercilessly beat the poor man when he didn't go along with it. The exceptions that prove the rule are Kintaros and Deneb. Kintaros fulfilled the spirit of his host's wish, and only cut the actual training short in order to protect his host in the past from the rhino Imagin. Deneb outright defected and became Sakurai's partner under his own volition.
  • Legion of Doom: Kai's army in the finale, consisting of almost every Imagin that Yuuto and Ryotaro ever fought.
  • Literal Genie: The Armadillo Imagin interprets its victim's wish to "cut ties" with the Yakuza literally - it walks up to his bosses, cuts their neckties in half, and says "Contract fulfilled!"
  • Meaningful Name: "Imagin" is derived from the words "imagine", "djinn"(the arabic word for genie), "Â�今" ("ima", Japanese for "now"), and "Â�人" ("jin", Japanese for "person").
  • One-Winged Angel: Gigandeaths, in three forms: Heaven, Hades, and Hell.
  • Weaksauce Weakness: Should an Imagin take a Singularity point as their host, they'll have to negotiate a proper contract to be made, and be forced to either possess their host or be stuck as a ghost made of sand. As Ryotaro demonstrated, this can take a very long time to happen, although that could be more about how his partners were wilingly working with him than attempting to leave his service.

Scorpion Imagin (voiced by Nobutoshi Canna)

Spider Imagin (voiced by Chihiro Suzuki)

  • Expendable Clone: It is later revealed that he cloned himself (albeit with green eyes and his memories intact) to continue the contract holder's wish. However, he went for a differently alternative plan: instead of taking his contract holder's younger sister from the hospital and intending to take her atop of an electric tower to let her see the stars, he decided to cut the power, shutting off all of the electricity in the city as a result.

Bloodsucker Imagin (voiced by Nobuo Tobita)

Wasp Imagin (voiced by Shouto Kashii)

Bluebird Imagin (voiced by Mitsuaki Hoshino)

Oct Imagin (voiced by Kenjiro Tsuda)

Armadillo Imagin (voiced by Wataru Takagi)

  • Epic Flail: One of his weapons.
  • Mistaken Identity: Momotaros confused his Animal Motif as a shrimp. This Imagin immediately corrected that, stating the near-invincible villain is an armadillo.
  • Rolling Attack: Similar to how an actual armadillo would curl itself into a ball.

Albinoleo Imagin (voiced by Takaya Kuroda)

Snowman Imagin (voiced by Toru Okawa)

Death Imagin (voiced by Hiroshi Yanaka)

    Characters Introduced in Ore, Tanjou! 

Gaoh/Kamen Rider Gaoh (portrayed by Hiroyuki Watanabe; suit actor Yoshifumi Oshikawa)

The Big Bad of the first movie, Gaoh is a thief-king who, along with a gang of rogue Imagin following him, targets time trains. After getting Ryotaro to chase an Imagin to 2000, he stole the DenLiner in order to go further back in time, as well as to obtain the Master Pass from Owner, which allows its user to go to any time period they wish. Upon arriving in the Sengoku period, he manipulates Yukimura Sanada into helping him uncover the GaohLiner, a time train originally named "God's Train" due to its ability to control time, even being able to erase Singularity Points. In the end, Gaoh is brought down by the combined efforts of all four Den-Os (collected from various points in time by Yuto) and Zeronos.

  • BFS: GaohGasher Sword Mode.
  • Big Bad: Of Ore, Tanjou!.
  • Big Eater: Quite literally; Gaoh spends most of his non-battle scenes munching on large quantities of food, such as whole turkey legs or pineapples.
  • Catch-Phrase: "Everything, I'll devour it all." Japanese 
  • Cool Old Guy: Hiroyuki Watanabe was 51 during filming, making him the oldest actor to portray a Kamen Rider.
  • Death by Genre Savviness: Doesn't wait for Sword Form to finish charging up his Finishing Move, going in for the kill, except that Momo actually anticipated this; at close proximity, Gaoh was left vulnerable to Extreme Slash, Special Version.
  • Finishing Move: Tyrant Crash (similar to Den-O's Extreme Slash).
  • Gang of Hats: his Imagin followers are all reptilian.
  • In the Style of...: Double-Action Gaoh Form = Death Rock. Also the only Double-Action variation sung solo.
  • No Body Left Behind: After Den-O kills him he's 'consumed by time' and reduced to sand.
  • No-Holds-Barred Beatdown: his first henshin in order to fight Zeronos can be described as this.
  • Omnicidal Maniac: He wanted to destroy time itself.
  • Palette Swap: The Gaoh costume is built from a Den-O costume, but it's still pretty distinct...at least until they used it to build Yuuki from the third movie...
  • Single-Stroke Battle: How Den-O finally finishes him.
  • Straw Nihilist: His goal is to destroy all time because he's grown bored of it and considers it pointless.
  • Why Don't Ya Just Shoot Him?: After uncovering the GaohLiner, Gaoh heads to Ryotaro's birthday with the intent of erasing the day from existence, therefore destroying Ryotaro AND Den-O.
  • Villain Song: While he doesn't sing it in the movie itself, Double Action Gaoh Form is added to the director's cut of the movie. His is also the only solo version of the song.

Molech Imagin (voiced Hidenori Tokuyama)

  • Lizard Folk: He seems to be based on an actual spiked reptile, known as the moloch.

Cobra Imagin (voiced by Takashi Hagino)

Salamander Imagin

Gecko Imagin

Newt Imagin

    Characters Introduced in Climax Deka 

Kazuya Suzuki (portrayed by Ryota Murai)

A police detective, Suzuki is assigned to work with the DenLiner Police in order to investigate the rash of Imagin and Fangire-related crimes that have been on the rise lately. Initially he doesn't mesh with the team at all, being freaked out by the Imagin and blindly pursuing the criminal Seiya Kuroki. Eventually they learn that his father Kazuma Suzuki (portrayed by Ryoji Morimoto) was a great policeman and he just wants to live up to his example.

  • Disappeared Dad: His father was a cop who died on the job when Kazuya was still very young.
  • This Is Something He's Got to Do Himself: Though Hana could kick Kuroki's butt five ways from Sunday, she lets Suzuki collar him, even if it does mean a drawn-out fight where he takes his share of lumps.
  • "Well Done, Son!" Guy: His goal is to follow in his father's footsteps. Amusingly, during their trip to 1986 to give Kazuya closure, we hear his father remark that he wants better for his son.
  • What the Hell, Hero?: Momo chews him out for foolishly infiltrating Negataros' HQ without any backup, leading to him getting captured. Granted, it was because the rescue attempt mounted by the DenLiner Police nearly cost them their lives.


Negataros/Kamen Rider Nega Den-O (voiced by Hikaru Midorikawa; suit actor Jiro Okamoto)

The Big Bad of Climax Deka, Negataros is a rogue Imagin who survived Kai's death and struck out on his own, attempting to found an Evil Organization. In his quest, he recruited human criminals as well as Imagin and Fangire, and eventually drew the DenLiner Police's notice when he stole Owner's spare Rider Pass. In the final battle, he used the Pass to transform into Nega Den-O, but was taken down by the combined efforts of the DenLiner crew and Kamen Rider Kiva.

  • Ascended Extra: Negataros gets a great deal of expansion in Den-O's S.I.C. Hero Saga story, a text series published in Hobby Japan Magazine. The story, an alternate version of Climax Deka, has Negataros travel to 1971 and join forces with Shocker, the evil organization of the original Kamen Rider, which leads Ryotaro and Yuto to pursue and eventually team up with the Showa Kamen Riders.
  • Evil Twin: Of Momotaros, as well as Den-O Sword Form.
  • Finishing Move: As Nega Den-O, he can use any of Den-O's primary four finishers, though in Climax Deka we only see the Nega Wild Shot. The arcade game Ganbaride shows the Negastreme Slash, as well as giving Negataros himself a move that combines all four finishers, called Hell's Quartet.
  • Japanese Pronouns: "Ore-sama".
  • The Mafia: What he wants to be, apparently.
  • Orcus on His Throne: Didn't do anything significant, just bragging about his "evil syndicate", at least until the movie's climax.
  • Palette Swap: Almost literally; Negataros is a negative-colored Momotaros, and Nega Den-O is Sword Form painted purple with blue tribal flame-like markings.
  • Weapon of Choice: Nega DenGasher, with all the modes of the orignal.: Cool Sword, Blade on a Stick, An Axe to Grind and Handguns.


Featured Imagins

Pink Rabbit Imagin

Clown Imagin (voiced by Chihiro Suzuki)

    Characters Introduced in Final Countdown 

Kotaro Nogami/Kamen Rider NEW Den-O (portrayed by Dori Sakurada; suit actor Seiji Takaiwa for Final Countdown, Makoto Ito for following films)

Ryotaro's Grandkid From The Future. He grew up listening to stories of Ryotaro's exploits from Owner, and eventually became the new Den-O along with his partner Imagin Teddy. The smug, arrogant Kotaro looks down on Ryotaro and the Taros, thinking them to be weak fools who could barely get the job done, and stepping in to take over as the protector of the timeline. However, after fighting alongside the younger Ryotaro and his allies, Kotaro gained an honest respect for his grandfather and mellowed out a good deal.

  • Amazingly Embarrassing Parents: His grandfather, Ryotaro, though Kotaro later drops the attitude.
  • An Axe to Grind: Kintaono (Kintaros in Episode Blue).
  • Blade on a Stick: DenGasher, Naginata Mode (Vega Form, when Deneb possesses him in Onigashima Battleship).
  • Break the Haughty: Momotaros has a talk with Kotaro that makes him more understanding of his supposedly "weak" grandfather.
  • Catch-Phrase: "My strength is *snaps fingers twice* the real thing.".
  • Character Tics: Snapping his fingers. In Final Countdown, he has Teddy set up a countdown of how long it'll take him to defeat an opponent; as a show of his arrogance it tends to be a low number, always below 30 seconds. The real sign that he's matured is when Teddy asks for a count against Shiro and Kotaro replies "The real battle starts at zero!"
  • Cool Sword:
    • Momotaken (Momotaros in Let's Go Kamen Rider).
    • DenGasher, Sword Mode (Strike Form, when Teddy is fighting alongside him).
  • Distressed Dude: His capture is an important part of Onigashima Battleship.
  • Embarrassing First Name: He dislikes it because apparently in the future it gained the connotation of being a "country" name.
  • Epic Flail: Uratazao (Urataros in Episode Blue).
  • Finishing Move:
    • Strike Form:
      • Counter Slash: A Diagonal Cut with the MacheTeddy.
      • Strike Spurt: New Den-O's Rider Kick.
    • Vega Form: Brandish Dive.
  • Kid from the Future: He's a strange case, seeing as how Ryotaro never had any romantic interests within the series; early press on the Cho Den-O Trilogy implied that his father would appear, but this turned out to be false.
  • Lamarck Was Right: He seems to have inherited Ryotaro's bad luck of all things...
  • Machete Mayhem: MacheTeddy.
  • Morph Weapon: Kotaro has the power to change any Imagin into a weapon for him to usenote .
  • Powers via Possession: Averted with Strike Form, but played straight with Vega Form needing Deneb to possess Kotaro.
  • Real Life Writes the Plot: Sort of. One of the big reasons they switched from Ryotaro to Kotaro is because Ryotaro's actor, Takeru Satoh, made it big and Toei couldn't really afford his agency's set salary (despite Takeru always saying that he loved playing Ryotaro). This is also the reason why Takuya Mizoguchi replaced Satoh as Ryotaro from The Onigashima Battleship onwards.
  • Rearrange the Song: Double-Action Strike Form (rock and roll), finally introduced in the Chou Den-O Trilogy.
  • Swiss Army Weapon: Like his Grandpa, Kotaro has his own DenGasher that can be assembled in any mode.


Teddy/Neotaros (voiced by Daisuke Ono; suit actor Shinichi Kaneda)

Kotaro's partner Imagin, Teddy is quiet, polite, and reserved. Unlike the other heroic Imagin who possess their contractors, he assumes the form of a two-handed sword dubbed the MacheTeddy in order to aid Kotaro in battle. He attempts to subdue Kotaro's brashness, and often ends up apologizing to the DenLiner team after the young man leaves the room. His capture while attempting to spy on Shiro gives the first indication that Kotaro might have a softer side, and the two are friends and partners despite their differing personalities and the master/servant relationship they seem to exhibit.

  • Empathic Weapon: Teddy can transform into New Den-O's weapon, the MacheTeddy.
  • Meaningful Rename:
    • Originally he was Neotaros, but after Kotaro became disillusioned with Ryotaro, he was rechristened Teddy.
    • In Episode Blue, when Teddy is briefly contracted to Owner, his name is changed to Aleksandrovic.
  • Only Sane Man: A down-to-earth kinda guy, especially when compared to the other Imagin.
  • Stealth Pun: In the anime short before Episode Blue, the Imagin are eating chicken tendon, and they wouldn't understand why Teddy is crying his eyes out just watching them.
  • Talking Weapon: His MacheTeddy form.
  • Weapon Tombstone: In Let's Go Kamen Riders, Teddie gets killed in the past trying to protect the Rider Scouts from Shocker. The scouts plant his remains, MacheTeddy, in one of their hideouts, in order for the Riders in the future to find the Time Capsule buried underneath.
  • You ALL Look Familiar: Teddy's appearance came from Kotaro's listening of the Owner's stories about his grandfather, Momotaros and the other Imagin. Thus he resembles all four Taros while maintaining his own image.

Shiro/Kamen Rider Yuuki Hijack Form (portrayed by Yuki Matsumura; suit actor Kazutoshi Yokoyama)

The primary antagonist of Final Countdown, Shiro was a man from the Edo period who lost Sora, the love of his life, and was unable to move on. After dying, he discovered the Ghost Train and plotted to reverse the worlds of the living and the dead, bringing Sora back to life no matter the cost. He kidnapped Ryotaro in order to further his goals, but eventually had to personally enter battle as Yuuki Hijack Form.

  • Affably Evil: While Ryotaro is virtually his prisoner, Shiro initially treats him in a civil manner, at least until Ryotaro starts showing signs of breaking free of Shiro's control.
  • Afterlife Express: The Ghost Train, a spectral steam engine with a skull mounted on the face, somewhat reminiscent of Final Fantasy VI's Doomtrain.
  • Battle Tops: Exploding toy tops.
  • BFS: SavageGasher; it's made up of two complete DenGasher sets.
  • Finishing Move: Terminate Flash
  • Gang of Hats: Fitting in with this ability, Shiro's Imagin minions are associated with darkness (Ghost, Phantom, Shadow).
  • Love Makes You Evil: He's so blinded by his mission, that he fails to realize that Sora never wanted him to do it.
  • Palette Swap: The Yuuki suit is essentially a black Gaoh suit minus the chest "fangs", plus coattails, two unique DenKamen, a color changing rail-scarf, and Hijack Form gains a mechanical gauntlet.


Ghost Imagin (voiced by Hiroshi Kamiya)

Phantom Imagin (voiced by Takuma Takewaka)

Shadow Imagin (voiced by Tomokazu Sugita)

  • Palette Swap: A modified variation of the AntHopper Imagin costume.

    Characters Introduced in Onigashima Battleship 

Yu (portrayed by Ruka Sawaki)

Nicknamed "Tokyo Boy" by fellow classmates, due to him living with his grandmother in the countryside after moving from Tokyo. Prefers the busier city life instead of the dirtier country life.

  • It Was with You All Along: The Kirifuda that the DenLiner crew and the Oni had been looking for. He uses it to bargain with Owner in order to ride DenLiner.
  • Parental Abandonment: His mother died long before the events of the movie and his father is in a foreign country, leaving him in his grandmother's care.
  • Precocious Crush: Instantly smitten with Toki, the girl that leads the fight against the Oni Brothers, at first sight. Though it might be less of this and more that she reminded him of his deceased mother. The Other Wiki mentions that she is Yu's mother's ancestor.
  • The Stinger: Yu is revealed at the end as a younger Yuto Sakurai through a Meaningful Echo of what Yu said earlier.


Toki (portrayed by Akina Minami)

Toki is the protector of the Kirifuda during the Muromachi period, protecting it from the Oni Brothers with her master archery skills. She is the ancestor of Yu's mother.

  • Identical Ancestor: Subverted that though Yu's mother's face was never seen, Yu said to Toki that they look alike.
  • Taking the Bullet: She took a hit meant for Yu, leaving her injured.


Kuchihiko/Goldra (portrayed by Eisuke Sasai)

  • Big Bad: Although his brother is also one of the main villains of the movie, he has the bigger role of the two, and lasts the longest.
  • Even Evil Has Loved Ones: The two oni, despite being time-traveling conquerors, genuinely care for each other, and Goldra goes berserk when he's killed.
  • Failed a Spot Check: For Rule of Funny. He didn't see Teddy standing right in front of him when he was riding the DenLiner.
  • Last Villain Stand: Momo tries to talk him into abandoning the Onigashima battleship when it's on the brink of destruction, but Goldra refuses, resulting in a final skirmish between the two.
  • Villainous Breakdown: Goes completely berserk when his brother's killed.
  • Would Hurt a Child: Like his brother, he tried to hurt Yu but Toki took the hit.


Mimihiko/Silvara (portrayed by Shingo Yanagisawa)

  • Even Evil Has Loved Ones: Genuinely loves his brother, to the point of sacrificing himself to save him from a fatal blow.
  • Lightning Reveal: At the beginning of the movie, his Rider form appears when lightning flashes on the screen.
  • Taking the Bullet: Shields his brother from both New Den-O's Brandish Dive and Super Climax Form's Rider Kick, which proved to be fatal for Silvara.
  • Would Hurt a Child: Even though Yuu only stumbled upon them by accident, Mimihiko decides to kill him for no other reason than he's bored.

    Characters Introduced in Chō Den-O Trilogy 

Reiji Kurosaki/Kamen Rider G Den-O (portrayed by Yuta Furukawa, suit actor Norihito Itō), Eve (voiced by Hiroki Takahashi)

A member of the G-Men, Kurosaki uses the artificial Imagin Eve to protect the timestream as Kamen Rider G Den-O. He initially appears chasing Daiki Kaitou/Kamen Rider DiEnd, who was attempting to cause a Time Paradox by killing his past self, but then he arrests the Taros as well, Eve claiming that their mucking about time with the DenLiner will only cause trouble. While he pursues Kaitou, the DenLiner crew tries to sort out the situation and figure out what Kaitou's overall goal is in the incident.

  • A.I. Is a Crapshoot: His artificial Doberman Pinscher Imagin, Eve, is a Knight Templar.
  • Ax-Crazy: Eve doesn't take Kurosaki's Heel–Face Turn very well...
  • Awesomeness by Analysis: Eve analysizes the opponent and can give G Den-O a command of where to attack next with great effect and does the same with his Perfect Weapon to counter finishers. However, this only works if he's facing one attack at once. When Eve takes over as G Den-O and goes Ax-Crazy, he begins doing this on his own.
  • Bling-Bling-BANG!: Out of his Rider form, his main weapon is an elaborate gold revolver, which Daiki attempted to steal in 2008.
  • Finishing Move: Although not mentioned in the movie, the Gun Mode's finisher is called World Punish, and the Jutte Mode's is called World End.
  • Gender-Blender Name: Eve.
  • Heel–Face Turn: Daiki reveals his entire plan was to not only retrieve the treasure he never did steal the last time, but to save Reiji's own 'treasure', a large number of letters from Reiji's mother, who Reiji believed abandoned him. At this reveal, Reiji breaks down and changes his ways...however, Eve goes Ax-Crazy...
  • Heel Realization: Reiji has one when he's given the letters from his mother that were kept from him and realizes she really did care about him, triggering his Heel–Face Turn.
  • Inspector Javert: Seeks to arrest not just Daiki, but the entire DenLiner crew as well for their "crimes against time". Once they are captured and subsequently escapes, he and Eve decides to just execute them.
  • Kill All Humans: After Reiji pulls a Heel–Face Turn, Eve goes Ax-Crazy and decides this is the best way to police time.
