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

The protagonist and eponymous Kamen Rider, Ryotaro is quite possibly [[CosmicPlaything the unluckiest being on Earth]] (and a high school drop-out supporting his only other family member, his older sister Airi); every day is [[TheChewToy 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 [[RippleEffectProofMemory Singularity Point]], and said girl and Imagin effectively "railroad" him into becoming Den-O. Even though by his own admission [[TheEveryman he's not exceptionally strong, smart, or brave]], when the chips are down his true strength appears in the form of [[{{Determinator}} unstoppable determination]]. In a way, his horrid luck could be seen as a [[CursedWithAwesome mixed blessing]], since he's been through so much that it takes a lot to really faze or hurt him. He's also [[TheHeart very good at reading people's emotions and true feelings]]; Ryotaro's ultimate strength may lie in his [[AllLovingHero unflappable kindness]]. [[spoiler:His strong feelings towards his friends are the reason for the existence of Den-O's first SuperMode 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

* {{Adorkable}}: Is he ever.
* AllLovingHero: He is willing to help other people whenever possible.
* BewareTheNiceOnes: As noted above, it takes a lot to rile him [[spoiler:such as the death of Yuto]], but when it happens, [[TranquilFury you should run]].
* {{Bishonen}}
* CallingYourAttacks: [[FinishingMove Hissatsu Waza!]]...um...''Densha Giri''! [[note]]Train Slash![[/note]]
* TheCastShowoff: Takeru Satoh portrays 1 character who's gained a total of 7 different possessed personalities (some of them by force), sings in every version of Double-Action (except Gaoh Form, Coffee Form, Climax Form, and Strike Form), his own solo song, Real-Action, and, thanks to Ryutaros, has an excuse to demonstrate his breakdancing skills.
* {{Catchphrase}}: "Let's go, Everyone!" [[labelnote:Japanese]]''"Minna, ikuyo!"''[[/labelnote]] settled in after he gained Liner Form.
* ClassicalAntiHero
* CosmicPlaything: 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?
* {{Determinator}}
* TheEveryman
* FaceHeelTurn: Forced to do so by Yu-Ki in ''Final Countdown'' but is later rescued.
* FinishingMove: 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]]A horizontal slash with [=DenLiner=] Gouka's [=AuraLiner=] covering Den-O.[[/note]]
** Ura-Rod Mode: ''[=DenKamen=] Attack'' [[note]]A forward lunging stab with [=DenLiner=] Isurugi's [=AuraLiner=] covering Den-O.[[/note]]
** Kin-Ax Mode: ''[=DenKamen=] Chop'' [[note]]Never shown, but is said to be a forward bashing with [=DenLiner=] Rekkou's [=AuraLiner=] covering Den-O.[[/note]]
** Ryu-Gun Mode: ''[=DenKamen=] Shot'' [[note]]A projectile thrust with [=DenLiner=] Ikazuchi's [=AuraLiner=] covering Den-O. A variation involves the [=DenKamen=] Sword being used as a gun, which fires purple beam projectiles.[[/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.
* TheHeart
* TheHero
* HonorBeforeReason: 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 [[CurbStompBattle beating him senseless]].
* IdentityImpersonator: During the final arc, while stranded in the past, [[spoiler:Ryotaro impersonates ''himself'' in order to find out the secret of his family from his sister.]]
* InTheStyleOf: 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.
* LockedOutOfTheLoop: [[spoiler: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.]]
* MasculineGirlFeminineBoy: Feminine Boy to Hana's Masculine Girl.
* MeaningfulName: "Ryotaro" means "good boy".
* MultiformBalance: The forms Ryotaro can assume on his own.
** JokeCharacter: Plat Form
** FragileSpeedster: Liner Form
* TheNthDoctor: 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 HandWave about how changes to the past do this sort of thing all the time.
* ParentalAbandonment: Ryotaro's parents died when he was young, leaving his sister and grandmother to raise him.
* ThePollyanna: A rare male version.
* PowersViaPossession: How Ryotaro is able to access most of Den-O's forms.
** ManySpiritsInsideOfOne: In his Climax and Super Climax Forms.
* RaisedByGrandparents: As mentioned in ''Ore, Tanjou!''
* RippleEffectProofMemory: One of the defining characteristics of a Singularity Point. However, a PlotHole opened when it was revealed in the finale that [[spoiler:Sakurai and Airi's plan erased his memory of their daughter]] in the past. [[spoiler:It was one of Sakurai's cards that erased his memory, but he regained it, for the most part, upon meeting Yuto.]]
* SensitiveGuyAndManlyMan: Sensitive Guy to Yuto's Manly Man.
* ShrinkingViolet: Ryotaro during the beginning of the series was a cowardly type and usually shy.
* SkunkStripe: Whenever an Imagin possesses him, he gets a different color streak in his hair.
* ThisLoserIsYou: Has elements of it, but gets better.
* TimeShiftedActor: Aside from Takeru Sato and Takuya Mizoguchi's [[MyFutureSelfAndMe 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).
* TookALevelInBadass: After he achieves Liner Form, he comes over as much more serious and determined than at the start of the series.
* WeaponOfChoice: HeroesPreferSwords
** [[SwissArmyWeapon Swiss Army]] {{BFS}}: [=DenKamen=] Sword; like the [=DenGasher=], it can emulate whatever Den-O weapon the Liner Form is imitating.
** CoolSword: [=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)
* [[YouGottaHaveBlueHair You Gotta Have Some Color In Your 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 [[spoiler: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 [[LastOfHisKind 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 [[DopeSlap 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}}. [[spoiler: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.]]

* ActionGirl: 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.
* BadassAdorable: As Kohana.
* BadassNormal: Powerful enough to knock the Taros out.
* [[spoiler:BarrierMaiden: As the Junction Point.]]
* CoolBigSis: Treats Ryotaro this way before being de-aged.
* DopeSlap: A master of this trope. Her punches are what help mellow Sieg's arrogant JerkAss-ness.
* [[spoiler:MacGuffinGirl]]
* [[spoiler:KidFromTheFuture]]
* MasculineGirlFeminineBoy: Masculine Girl to Ryotaro's Feminine Boy.
* MegatonPunch: Gets even more impressive when she becomes Kohana and suffers no drop in power.
* TheNthDoctor: Tamaki Matsumoto for Yuriko Shiratori, a case of...
** RealLifeWritesThePlot: Shiratori left the series due to the stresses of filming.
* PerpetualFrowner: When played by Yuriko Shiratori. Not so much when Tamaki Matsumoto took over.
* SmallGirlBigGun: Wields a [[{{BFG}} bazooka]] as her WeaponOfChoice in ''Climax Deka''.
* SuperStrength: Played mainly for laughs whenever she abuses the Imagin, to the point where they're all afraid of her.
* TeamMom
* TokenMiniMoe: As Kohana.
* TomboyAndGirlyGirl: Tomboy to Naomi's Girly Girl.
* {{Tsundere}}: For the Imagin; she even cried when [[spoiler:Ura, Kin, and Ryu seemingly vanished]].
* UnlimitedWardrobe: Every time she steps off the [=DenLiner=], she wears a different outfit.
* WaifFu: Exhibited more as Kohana.
-----
!!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.

* [[spoiler:BigDamnHeroes: Rescues Kintaros and Urataros in the past, and brings them alongside Sieg to the present for the final battle.]]
* CordonBleughChef: She puts salt, pepper, ''flour'', and '''''wasabi''''' in her coffee. The only people who like it are the Imagin.
* GenkiGirl: Usually seen with lots of energy and a smile on her face.
* InTheStyleOf: Double-Action Coffee Form, along with Airi = Light Pop.
* PaintedOnPants: With arrows.
* ThePollyanna: Hardly seen without her smile.
* TomboyAndGirlyGirl: 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".

* ActingForTwo: Ishimaru plays both the Owner and the Station Master; whenever the resemblance is commented upon in-series, the Owner says it's just the observer's imagination and insists that they're quite different.
* BerserkButton: Mess with the rules of the [=DenLiner=] and the normally mellow Owner might slap you with a Denial of Passage ticket.
* BigGood: Technically.
* CampGay: The Station Master.
* CloudCuckoolander
* EccentricMentor
* EveryoneCallsHimBarkeep: The Owner and the Station Master have no names other than their job titles.
* IdenticalStranger: The Owner and the Station Master, obviously.
* InexplicablyAwesome: 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.
* RunningGag: Because of the above trope, characters who meet both the Owner and Station Master at the same time actually confuse them for twins.
* SeriousBusiness: Food Flags toppling over ''before'' he finishes his food.

!!Momotaros[=/=]Kamen Rider Den-O Sword Form (voiced by Creator/ToshihikoSeki; 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. {{Hotblooded}} and hot-headed, Momotaros is [[BloodKnight 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 BoisterousBruiser might seem at odds with Ryotaro's normal personality, it's his eccentricies like [[AssKickingPose posing]], [[InTheNameOfTheMoon pre-battle speeches]] and [[CallingYourAttacks 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".

* AnimeHair: A side effect on people possessed by him.
* BigBrotherInstinct: Eventually develops one for Ryotaro as well as the other Taros. [[spoiler:He even takes it personal when he thought Ura was EvilAllAlong ([[FakeDefector he wasn't]]).]]
* BloodKnight: Has elements of it at the start, before [[CharacterDevelopment developing]] into a...
* BoisterousBruiser
* ButtMonkey: Ryotaro's luck seems to have rubbed off on him. This is exemplified in the fourth movie; ''[[AssShove literally]]'', even.
* BrainBleach: His reaction to learning that [[spoiler: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.
* CallingYourAttacks: "Hissatsu! My finishing attack...Part (number/____Version)!"
* CatchPhrase
** "Ore, sanjou!" [[labelnote:English]]''"Here I am!"''[[/labelnote]]
** "From start to finish, I'm always at a climax!" [[labelnote:Japanese]]''"Ore wa, saisho kara saigo made, Climax daze!"''[[/labelnote]]
** "Let's go, go, go!!" [[labelnote:Japanese]]''"Ikuze, ikuze, ikuze!!"''[[/labelnote]]
* CharacterTics: 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.
* CriticalResearchFailure: In-universe, PlayedForLaughs.
-->'''Momo''': ''It's Mt. Fuji!''
-->'''Hana''': ''What are you saying? That's not Mt. Fuji, that's a '''pyramid'''!''
* {{Deuteragonist}}
* FishOutOfTemporalWater: 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.
* FourIsDeath: [[LampshadeHanging Lampshades]] it when Ryotaro points out that he skipped over number 4 in his [[CallingYourAttacks 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.
* FinishingMove
** ''Extreme Slash''
** ''[=DenRider=] Kick'': A HurricaneKick. First used in the fourth movie.
* {{Hotblooded}}
* IdiotHair: The strand of red hair when possessing Ryotaro literally stands out.
* IdiotHero: [[LampshadeHanging Lampshaded]] through a GilliganCut by ''Series/KamenRiderDecade''.
* IKnowYoureInThereSomewhereFight: in ''Final Countdown'', to Ryotaro/Yu-ki Skull Form.
* InTheNameOfTheMoon: Either of Momo's catchphrases suffices.
* InTheStyleOf: The original Double-Action ([[FanNickname nicknamed]] Sword Form to avoid confusion) = Eurobeat. Climax Jump Sword Form = Hard Rock.
* JackOfAllStats
* JapanesePronouns: "Ore"
* JerkWithAHeartOfGold
* TheLancer
* LargeHam
** IncomingHam: [[ExactlyWhatItSaysOnTheTin Exactly what his]] {{Catchphrase}} [[ExactlyWhatItSaysOnTheTin says.]]
* LiteralAsskicking: He's fond of doing this to his opponents, whether it involves his actual feet or even his sword.
* TheNicknamer: 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)
* ReallyGetsAround: Thanks to [[CrossOver crossovers]] and other hijinks, Momo has the distinction of having possessed no less than four different Kamen Riders: Den-O, [[Series/KamenRiderDecade Decade]], [[Series/KamenRiderKiva Kiva]], and [[Series/KamenRiderKuuga Kuuga]], though in the case of the latter two he only possessed them as civilians and never used their unique Rider powers.
** In ''Let's Go Kamen Rider'', he possesses [[Series/KamenRiderOOO Ankh]] while ''he's'' already possessing the dead body of Shingo Izumi. He also possessed Eiji in a recent stage show.
* RedEyesTakeWarning: People possessed by Imagin have their eyes change color to match; Momo, obviously, makes them go red.
* RedOniBlueOni: The red to Urataros' blue.
* RuleOfCool: What Momo usually tries to go by.
* RunningGag: Being mistaken for an Oni. It doesn't help that he was designed that way.
* ScarfOfAsskicking: 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.
* SuperDrowningSkills: He can't swim.
* TrademarkFavoriteFood: Pudding. He even starts up a pudding shop in ''Imagin Anime''.
* TranslationConvention: 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.
* UsefulNotesOnJapaneseCulture: Based off the legend of [[http://en.wikipedia.org/wiki/Momotaro Momotaro]].
* WeaponOfChoice: HeroesPreferSwords
** {{BFS}}: [=MomoSword=]
** CoolSword: [=DenGasher=] Sword Mode
* WeWantOurJerkBack: The whole "Gold Gentleman Coffee" incident; Ura was so weirded out that he prefers the old Momo over the gentlemanly one.
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Dogs?]]
* WolverinePublicity

!!Urataros[=/=]Kamen Rider Den-O Rod Form (voiced by KojiYusa; 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 ConsummateLiar, 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...

* AnimalMotifs: [[TurtlePower Turtle]]
** He even thinks it's personal when another turtle-based Imagin appears to steal his limelight.
* CatchPhrase: "Mind if I reel you in?" [[labelnote:Japanese]]''"Boku ni Tsuraretemiru?"''[[/labelnote]]
* CharacterTics: Holds his left hand near his face, as if he's holding something.
* ChivalrousPervert
* ConsummateLiar: In addition to his own skills, he claims his goal is to teach Ryotaro to be a better liar.
* [[spoiler:FakeDefector: Pulls this off in the final story arc.]] He pulls it off really well, too, thanks to his [[ConsummateLiar nature]].
* FinishingMove: ''Solid Attack'', followed by ''[=DenRider=] Kick''.
* GuileHero: A liar and a trickster, but still has a good heart.
* InTheStyleOf: Double-Action Rod Form and Climax Jump Rod Form = Ska.
* JapanesePronouns: "Boku"
* TheNicknamer: Calls Momotaros "[[SempaiKohai 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.
* ReallyGetsAround: In addition to flirting with anything with two X chromosomes, Ura is also the Imagin who possesses the most characters in the whole of ''Den-O'' and its related materials (Ryotaro, Yuto, Kotaro, [[Series/KamenRiderKiva Jiro/Garulu]], [[Series/KamenRiderDecade Tsukasa Kadoya, Natsumi Hikari]], a [[Series/KamenRiderDecade DiEnd]]-summoned [[Series/KamenRiderAgito G-3]], and finally [=DiEnd=] himself).
* RedOniBlueOni: The blue to Momotaros' red.
* SexyManInstantHarem: 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.
* TheSmartGuy
* SpitTake: 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.
* StoicSpectacles: People possessed by him gain these in addition to the blue eyes and streak in their hair.
* StoneWall
* SuperNotDrowningSkills: As opposed to Momotaros. Justified that he's based on a turtle, who are good swimmers.
* UsefulNotesOnJapaneseCulture: Based off the legend of [[http://en.wikipedia.org/wiki/Urashima_Taro Urashima Taro]].
* WeaponOfChoice
** ArmedLegs: Climax Form's Kick Mode
** BladeOnAStick: [=DenGasher=] Rod Mode
*** EpicFlail: It also doubles as a fishing rod.
** DoubleWeapon: [=UrataRod=]
-----
!!Kintaros[=/=]Kamen Rider Den-O Ax Form (voiced by MasakiTerasoma; 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 [[HeavySleeper sleeps the day away]] until someone [[BerserkButton 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.

* AnimalMotifs: Bear
* TheBigGuy
* BerserkButton: DON'T EVER make a girl cry.
* BoisterousBruiser: Not violent like Momo, but still loves a good fight.
* BruiserWithASoftCenter
* CallingYourAttacks: In an odd variation, he only says the name of his FinishingMove ''after'' performing it, which Ryotaro [[LampshadeHanging specifically notes]] the first time he does it.
* CatchPhrase: "My strength has made you cry. Wipe your tears with this!" [[labelnote:Japanese]]''"Ore no tsuyosa ni omae ga naita! Namida wa kore de fuitoke!"''[[/labelnote]] Sometimes shortened to just "My strength has made you cry!" or just "You cried!" [[labelnote:Japanese]]''"Nakerude!"''[[/labelnote]]
* CharacterTics: Pops his neck by pushing a hand (or sometimes a finger) against his chin. The BadassArmFold is his default pose.
* CherryBlossoms: Parodied, as occasionally the transformation into Ax Form will be accompanied by fluttering...''tissues''. "Wipe your tears", indeed.
* TheDitz: 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.
* DoesNotKnowHisOwnStrength
* EvenEvilHasStandards: 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.
* FinishingMove: ''Dynamic Chop''
* GentleGiant
* HammerSpace: He can pull tissues out of thin air, apparently.
* HeavySleeper: And narcoleptic to boot; since he's a bear, this presumably represents hibernation. The only way to wake him up is by activating his BerserkButton.
* HonorBeforeReason: Demonstrated in his ADayInTheLimelight two-parter where he puts aside fighting the MonsterOfTheWeek 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. [[spoiler:Thankfully, he's right about the father, and the changes Kintaros caused mean the Imagin never became a threat, so Owner let him stay.]]
* ImplausibleDeniability: When Owner once said that Kintaros' snoring is a problem, Kintaros wakes up just to deny it.
* InTheStyleOf: Double-Action Ax Form and Climax Jump Ax Form = Enka.
* JapanesePronouns: "Ore"
* KansaiRegionalAccent
* TheKlutz: Seen moreso when he's possessing Honjo and Ryotaro than in his natural form.
* ManlyTears: 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.
* MightyGlacier
* TheNicknamer: 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".
* NobleDemon: The only one of the Taros to not start off as a VillainProtagonist.
* NoodleIncident: 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.
* ToBeAMaster: His desire to be the strongest warrior presumably comes from his original contractor Honjo.
* UsefulNotesOnJapaneseCulture: Based off the legend of [[http://en.wikipedia.org/wiki/Kintaro Kintaro]].
* WeaponOfChoice
** AnAxeToGrind: Kintaros Ax and [=DenGasher=] Ax Mode.
** {{Power Fist}}ed BladeBelowTheShoulder: Climax Form's Punch Mode

!!Ryutaros[=/=]Kamen Rider Den-O Gun Form (voiced by Creator/KenichiSuzumura; 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 [[CrowdSong 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.

* AnimalMotifs: [[OurDragonsAreDifferent Dragon]] (?)
* BreakTheCutie: Near the end of the series, Ryutaros gets confronted by Kai who [[spoiler: 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 more worse because Ryutaros was trying to give Airi a picture he made of her and couldn't. Poor guy.]]
* CatchPhrase: "Mind if I (something)?", most commonly "beat you" or "end it", followed by "Can't hear the answer!" [[labelnote:Japanese]]''"Kotae wa kiitenai!"''[[/labelnote]]
* CharacterTics: Spinning around during his CatchPhrase, followed by GivingSomeoneThePointerFinger.
* CheshireCatGrin: 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!
* [[CrowdSong Crowd Dance]]: A rare [[JustifiedTrope justified]] version. Sometimes he uses them to chase people down.
* CutenessProximity: He ''loves'' cute little animals, sometimes possessing Ryotaro just to pick up an animal and cuddle them.
* DanceBattler: When fighting, he moves around as if dancing.
* DestructiveSavior: He means well, but let's just say he's a ''terrible'' shooter.
* DragonRider: 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.
* FinishingMove: ''Wild Shot''
* FriendToAllLivingThings: He loves all types of animals, particularly kittens, puppies and birds.
* FunnyBackgroundEvent: 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. [[CloudCuckoolander Naomi]] is known to join him on occasion.
* GangstaStyle: Likes to wield his gun sideways in Gun Form.
* GlassCannon: Was originally the LightningBruiser before Wing Form was given that role.
* IconicItem: His BubbleGun. [[spoiler:Becomes a ChekhovsGun when it's one of the items that Kintaros gives to Ryotaro to complete their contract.]]

* InTheStyleOf: 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.
* JapanesePronouns: "Boku"
* KidAppealCharacter
* LaserGuidedTykebomb: Kai told him to kill Ryotaro and gain control of the [=DenLiner=]. Ryutaros decided not to do so due to his love for Airi.
* LoveRedeems: Decides not to kill Ryotaro after realizing that his death would make Airi cry.
* MurderTheHypotenuse: 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.
* NiceHat: Whenever he's possessing someone to go along with the wavy bangs and purple streak in the hair.
* TheNicknamer: 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.
* PetTheDog: The first indication that Ryuta has good qualities is when 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.
** Before that, he confronted the Dance Posse and asked them if they were the reason that the animals being fed in the park got frightened.
* [[PsychopathicManchild Psychopathic Imagin Child]]: Whenever he possesses Ryotaro, he somehow holds some kind of glee in chasing people down for no apparent reason. 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.
* PurpleEyes
* PurpleIsPowerful: Initially treated as the strongest of the four core Imagin, to the point that the other three had to work together to push him out of Ryotaro's body.
* ShouldersOfDoom: Gun Form.
* SummonBackupDancers: Being in a deserted location is no obstacle to his CrowdSong abilities.
* UsefulNotesOnJapaneseCulture: Conflicting information suggests that Ryuta is modeled on Tatsu no Ko Taro (Taro the Dragon Boy), or simply on Ryotaro's mental image of dragons in general. References in ''Imagin Anime'' and official books like ''IMAGINE: Detail of Heroes'' lend credence to the former.

!!Sieg[=/=]Kamen Rider Den-O Wing Form (voiced by Creator/ShinichiroMiki; suit actor Naoki Nagase)

An arrogant swan Imagin, inspired by the story "Swan Lake" and the character of 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.

* AgentPeacock
* AloofAlly: 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.
* AnimalMotifs: [[SwansASwimming Swan]]
* ArrogantKungFuGuy
* ButtMonkey: 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.
* CampStraight: Obsessed with "beauty" but has feelings for Hana.
* CatchPhrase: "Advent! To the top!" [[labelnote: Japanese]]''"Korin! Man wo Jishite!"''[[/labelnote]]
* CulturedBadass: He's based on a prince, and his form is the most powerful of Den-O's basic forms.
* DeusExitMachina: 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 [[spoiler:(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 [[spoiler: 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.
* EleventhHourRanger
* EverythingsBetterWithPrincesses: 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.
* FinishingMove: ''Royal Smash''
* TheFriendNobodyLikes: Most of the time, everyone sans Ryutaros seems reluctant whenever he appears.
* [[ManInWhite Imagin In White]]
* IncredibleShrinkingMan: Has the power to make people shrink to action figure-size by saying "Bow your head!"[[labelnote: Japanese]]''"Zu ga Takai!"'', lit. "Your head is high!"[[/labelnote]] The Imagin Anime gives him "Super Bow Your Head", which shrinks ''the whole world''.
* InTheStyleOf: Double-Action Wing Form = Arabic Pop
* ItsAllAboutMe: "The world revolves for my sake."[[labelnote:Japanese]]''"Sekai ga watashi no tame mawaru."''[[/labelnote]]
* JapanesePronouns: "Watashi"
* JerkWithAHeartOfGold: Despite his superority complex and belief [[ItsAllAboutMe 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.
* LightningBruiser
* LoveAtFirstPunch: Towards Hana.
* {{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.
* PerpetualMolt
* PowerGivesYouWings: Especially in Super Climax Form.
* SpellMyNameWithAnS: Some databooks list his name as '''Z'''ieg.
* StealthHiBye: 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.
* TheThingThatWouldNotLeave: For the [[Series/KamenRiderDecade Hikari Studio]]. Only [[CloudCuckooLander Eijiro]] wants him around, and it's for taking pictures anyway.
* TrueCompanions: Constantly refers to the other Imagin as "family", much to Momo's chagrin.
* WeaponOfChoice: When he's not [[BareFistedMonk fighting with his bare hands]], Sieg likes to be...
** DualWielding: Uses a weapon each composed of two pieces of the [=DenGasher=].

!!Airi Nogami (portrayed by Wakana Matsumoto)

Ryotaro's older sister and the owner of the Milk Dipper library cafe. She was forced to raise help 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 [[UnwantedHarem horde of lovestruck men]] who pack the shop from opening to closing. For her part, Airi remains [[ObliviousToLove 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. [[spoiler: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.]]

* BewareTheNiceOnes: 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'''.
* CoolBigSis: More like Sweet Big Sis, actually.
* CordonBleughChef: Her energy drinks and herbal cures are...well, read the "BewareTheNiceOnes" entry above.
* DistressedDamsel: ''Episode Red'' invokes this, since this is the condition of the contract between the Piggies Imagin and the [[VictimOfTheWeek Victim of the Movie]]: to put Airi in a dangerous situation so that he would be the one to rescue her, also invoking RescueRomance.
* InTheStyleOf: Double-Action Coffee Form, along with Naomi = Light Pop. [[http://www.youtube.com/watch?v=DHtLUnjCFfU No, seriously]].
* LaserGuidedAmnesia: [[spoiler:Inflicted willingly in order to protect the identity and location of the Junction Point.]]
* ObliviousToLove
* ThePollyanna
* [[spoiler:RedHerring: as the identity of the Junction Point.]]
* StarCrossedLovers: With Sakurai, as referenced in Zeronos' theme.
* UnwantedHarem: Not unwanted so much as [[ObliviousToLove completely unnoticed]].
* YamatoNadeshiko: 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:[[spoiler: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.

* HandsomeLech
* HotScoop
* RegularCaller: If Momo's the go-to guy for Imagin attacks, Seigi is the one the gang turns to for information on the VictimOfTheWeek.
* ThoseTwoGuys: With Miura
-----
!!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.

* IgnoredExpert: In regards to the Imagin, at least until Airi and Ozaki meet them in ''Climax Deka''.

!!Yuto Sakurai[=/=]Kamen Rider Zeronos

Because of the time-traveling nature of ''Series/KamenRiderDenO'', 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. [[spoiler: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 SuperMode 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.]]

* AngerBornOfWorry: In the finale, [[spoiler:upon seeing Deneb alive again, Yuuto was about to seemingly attack him again, only to fall into tears in Deneb's arms.]]
* BadassNormal
* BokeAndTsukkomiRoutine: Tsukkomi to Deneb's Boke.
* BroughtToYouByTheLetterS: (A)ltair and (V)ega, which is visible on both their corresponding Zeronos cards, the [=ZeroLiner's=] cars, and their {{Finishing Move}}s.
* CatchPhrase: "Let me say this to start: I'm pr-e-tty strong!" [[labelnote:Japanese]]''"Saisho ni itte oku! Ore wa ka~na~ri tsuyoi!"''[[/labelnote]]. On a couple of occasions, Yuto replaces the second part with "I'm pretty ticked off!"
** CatchphraseSpoutingDuo: Oftentimes, with Deneb.
* CharacterTics: GivingSomeoneThePointerFinger ("Let me say this to start! I'm pr-e-tty...") followed by the BicepPolishingGesture ("...Strong!").
* DeadlyUpgrade: [[spoiler:The Zero Form cards.]]
* DeusExitMachina: Hospitalized, and therefore absent, for a good portion of ''Final Countdown'' after TakingTheBullet 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.
* DidNotGetTheGirl: 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).
* [[DoesNotLikeSpam Does Not Like Shiitake Mushrooms]]
* FinishingMove
** [=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''
* HeroicWillpower: 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.
* HoldingBackThePhlebotinum: With good reason.
** And, apparently, Sakurai himself has a good reason for giving power with such a drawback in the first place. [[spoiler:Erasing [[HeroicSacrifice his (Sakurai's) own existence]] allows Yuto to [[ScrewDestiny write his *own* history]] (in another timeline, anyway).]]
* InTheStyleOf: Action-Zero = Rock. 2010 Version = Soft Piano.
* JerkassFacade: [[spoiler:Comes with the revelation about the Zeronos Cards, explaining that Yuto acts rude to keep people distant.]]
* JerkWithAHeartOfGold
* MultiformBalance: The forms Yuto can assume on his own.
** JackOfAllStats: Altair Form
** LightningBruiser: Zero Form
* MyHeroZero
* PowersViaPossession: Unlike Den-O, only one of Zeronos' forms requires Deneb to possess him to access it.
* [[spoiler:RaisedByGrandparents: As confirmed in ''Onigashima Battleship''.]]
* [[SixthRanger Second Rider]]
* SensitiveGuyAndManlyMan: Manly Man to Ryotaro's Sensitive Guy.
* SignificantReferenceDate: When Yuto first makes his debut in the series, he's holding a ticket for May 27th, 2007. Go on, guess the airdate of that episode.
* SweetTooth: Yuto really likes his coffee sweet, to the point where he puts '''way''' too much sugar in.
* UsefulNotesOnJapaneseCulture: Zeronos has a running theme of {{Tanabata}}, with Altair Form representing Hikoboshi the cowherd (hence the cow-head [=DenKamen=]) and Vega Form representing Orihime the weaver (hence the spindle [=DenKamen=]). This form also carries over to Yuto and Airi.
* WeaponOfChoice
** SwissArmyWeapon: [=ZeroGasher=]

*** TheStraightAndArrowPath: Bowgun Mode
** [[TalkingWeapon Talking]] [[MoreDakka Dakka]]: Denebick Buster

!!!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. [[spoiler: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.]]

* BadassLongcoat
* BigBrotherMentor
* BigDamnHeroes: When Den-O and Zeronos were having trouble with TheDragon, Sakurai himself steps up to help them in battle, assuming Altair Form.
* ChekhovsGunman
* GuileHero
* ThePlan: [[spoiler:Most of the show's plot is predicated on a plan by Sakurai and Airi to protect their daughter Hana from the Imagin.]]
* StarCrossedLovers: With Airi, as referenced by Zeronos' theme (see Yuto's UsefulNotesOnJapaneseCulture).
* WhatTheHellHero: [[spoiler: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 ([[spoiler:and New Den-O]]) Vega Form (voiced by HochuOtsuka; 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. [[spoiler: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.]]

* ApologisesALot: One of the humblest Imagins in existence.
* ArmCannon: Type 1; his hands can fire bullets from the fingers.
* BadassCape + ShouldersOfDoom: Vega Form.
* BattleButler: Does many things butlers do (shopping for food, cooking for Yuto, cleaning the [=ZeroLiner=]), has a very humble attitude, and assists Yuto in battle.
* BewareTheSillyOnes: 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).
* BokeAndTsukkomiRoutine: Boke to Yuto's Tsukkomi.
* CatchPhrase: Usually begins with Yuto's "Let me say this to start!" [[labelnote:Japanese]]''"Saisho ni itte oku!"''[[/labelnote]], 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" [[labelnote:Japanese]]''"Mune no kao ga kazari da!"''[[/labelnote]] a couple of times. He also says "Take care of Yuto!"[[labelnote:Japanese]]''"Yuto o yoroshiku!"''[[/labelnote]] both in conjunction with the first phrase and on its own.
** CatchphraseSpoutingDuo: Sometimes gives the tail-ends of Yuto's phrases.
* ChunkyUpdraft: When transforming into Vega Form.
* EmpathicWeapon: Transforms into the Denebick Buster whenever Zeronos assumes Zero Form, and can still talk to Yuto.
* FinishingMove
** [=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''
* TheHeart
* InTheStyleOf: Action-Zero = Rock. 2010 Version = Soft Piano.
* JapanesePronouns: "Ore"
* MaliciousMisnaming: Momotaros (and sometimes the other Imagins as well) likes to call him Odebu (a deformation on his name, which literally means "tubby").
* MightyGlacier: As Vega Form.
* NiceJobBreakingItHero: Because he didn't tell Yuuto of his plans of going through a Haunted House event, Yuuto thought that Deneb was in danger when the latter was scared out of his wits; thus, Yuuto had to use up a Zeronos card even before finding out what really happened. [[WhatTheHellHero Yuuto didn't like Deneb's actions one bit.]]
* NobleDemon
* ShipperOnDeck: Yuto/Airi.
* SixthRanger: With Yuto.
* SpotlightStealingSquad: In ''Onigashima Battleship''. [[LampshadeHanging Lampshaded]] in the ''Series/KamenRiderDecade'' net spinoff episode which advertised the movie.
* TrademarkFavoriteFood: Likes to put shiitake mushrooms in the food he makes.
* UsefulNotesOnJapaneseCulture: Inspired by the legend of [[http://en.wikipedia.org/wiki/Saitō_Musashibō_Benkei Benkei]], as well as [[http://en.wikipedia.org/wiki/Tengu Tengu]]. This second reference also ties into {{Tanabata}}, where a bridge of birds (represented by the star Deneb) allows the two lovers to be together.
* WeaponOfChoice
** [=ZeroGasher=] Bowgun Mode uses arches.
** [[{{BFS}} Big]] CoolSword: [=ZeroGasher=] Sabre Mode
** BladeOnAStick: New [=DenGasher=] Naginata Mode (New Den-O Vega Form, when he possesses Kotaro in ''Onigashima Battleship'')

* WhyDidItHaveToBe: He's very afraid of ghosts, as revealed in Episode 29.
* [[YouGottaHaveBlueHair You Gotta Have Green Hair]] and PowerMakesYourHairGrow: When possessing Yuto, present or past. [[spoiler:The latter referring to "Yu-kun".]]
* YouNeedToGetLaid: He once asked Urataros for dating advice to give to Yuto.

* [[spoiler:BigBad]]
* CatchPhrase: "I have the face for it, don't I?" [[labelnote:Japanese]]Ore, sōiu kao shiteru daro?[[/labelnote]]
* [[spoiler:FateWorseThanDeath: 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.]]
* [[spoiler:FauxAffablyEvil: 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''.]]
* GigglingVillain: Frequently seen with a creepy grin on his face and indulge himself in maniacal laughs.
* [[spoiler:TheManBehindTheMan: Is the driving force behind the Imagin but doesn't appear in person until close to the end.]]
* PsychicPowers
* [[spoiler: PsychopathicManchild: 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.]]
* TimeMaster: Unlike others, he's able to travel through time without a Time Train. [[spoiler: 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.]]
* ThatMakesMeFeelAngry: Does this a lot, and usually follows it up with his CatchPhrase above, asking other characters if his face shows that emotion. [[SlasherSmile It usually doesn't.]]
* [[spoiler:VillainousBreakdown: 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.]]
* WellIntentionedExtremist: [[spoiler:Arguably, since he's doing all of this for the sake of the Imagins' existence.]]
* YouHaveFailedMe: [[spoiler: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' MonsterOfTheWeek 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 [[OneWingedAngel revive as giant monsters]] called "Gigandeaths". [[spoiler: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).]]

* AnimalMotifs: as part of their fables and fairy tales theme designs.
* BeCarefulWhatYouWishFor: 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.

** Rather than bring Kai back, they've had the Leo Imagin stand in to represent the Imagin any time the Franchise/KamenRider evil organizations are gathered, like in ''Let's Go Kamen Riders''.
* EliteMook: the New Molech Imagin, which always come up in large numbers.
* JackassGenie: 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.
* LegionOfDoom: Kai's army in the finale, consisting of almost every Imagin that Yuuto and Ryotaro ever fought.
* LiteralGenie: The Armadillo Imagin interprets its victim's wish to "cut ties" with the {{Yakuza}} literally - it walks up to his bosses, cuts their '''neck'''ties in half, and says "Contract fulfilled!"
* MeaningfulName: "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").

[[folder:Characters Introduced in ''Ore, Tanjou!'']]

!!Gaoh[=/=]Kamen Rider Gaoh (portrayed by Hiroyuki Watanabe; suit actor Yoshifumi Oshikawa)

The BigBad 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.

* AffablyEvil
* BigBad: Of ''Ore, Tanjou!''
* BigEater: Quite literally; Gaoh spends most of his non-battle scenes munching on large quantities of food, such as whole turkey legs or pineapples.
* CardCarryingVillain
* CatchPhrase: "Everything, I'll devour it all." [[labelnote:Japanese]]''"Zennin, ore ga kutte yaru."''[[/Labelnote]]
* CoolOldGuy: Hiroyuki Watanabe was 51 during filming, making him the oldest actor to portray a Kamen Rider.
* [[CoolSword Cool]] [[{{BFS}} Big Sword]]: [=GaohGasher=] Sword Mode
* DeathByGenreSavviness: doesn't wait for Sword Form to finish charging up his FinishingMove, going in for the kill, [[spoiler:[[OutGambitted except]] that Momo actually anticipated this; at close proximity, Gaoh was left vulnerable to Extreme Slash, Special Version.]]
* FinishingMove: ''Tyrant Crash'' (similar to Den-O's Extreme Slash).
* GangOfHats: his Imagin followers are all reptilian.
* InTheStyleOf: Double-Action Gaoh Form = Death Rock. Also the only Double-Action variation sung solo.
* NoBodyLeftBehind: [[spoiler: After Den-O kills him he's 'consumed by time' and reduced to sand.]]
* NoHoldsBarredBeatdown: his first henshin in order to fight Zeronos can be described as this.
* OmnicidalManiac: He wanted to destroy time itself.
* PaletteSwap: 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...
* SingleStrokeBattle: How Den-O finally finishes him.
* StrawNihilist: His goal is to destroy all time because he's [[ForTheEvulz grown bored of it]] and considers it pointless.
* WhyDontYaJustShootHim: 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.
* VillainSong: While he doesn't sing it in the movie itself, ''[[http://www.youtube.com/watch?v=co_VVSB1My8 Double Action Gaoh Form]]'' is added to the director's cut of the movie. His is also the only solo version of the song.

[[folder: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 [[Series/KamenRiderKiva 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.

* ButtMonkey
* DisappearedDad: His father was a cop who died on the job when Kazuya was still very young.
* InspectorLestrade
* ThisIsSomethingHesGotToDoHimself: 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.
* ThisLoserIsYou
* WellDoneSonGuy: His goal is to follow in his father's footsteps. [[spoiler:Amusingly, during their trip to 1986 to give Kazuya closure, we hear his father remark that he wants better for his son.]]
* WhatTheHellHero: Momo chews him out for foolishly [[StormingTheCastle 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 Creator/HikaruMidorikawa; suit actor Jiro Okamoto)

The BigBad 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 [[Series/KamenRiderKiva 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 Series/KamenRiderKiva.

* AscendedExtra: 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 ''Series/KamenRider'', which leads Ryotaro and Yuto to pursue and eventually team up with the Showa Kamen Riders.
* CardCarryingVillain
* EvilTwin: Of Momotaros, as well as Den-O Sword Form.
* FinishingMove: 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''.
* JapanesePronouns: "Ore-sama"
* TheMafia: What he wants to be, apparently.
* OrcusOnHisThrone: Didn't do anything significant, just bragging about his "evil syndicate", at least until the movie's climax.
* PaletteSwap: Almost literally; Negataros is a negative-colored Momotaros, and Nega Den-O is Sword Form painted purple with blue tribal flame-like markings.
* WeaponOfChoice: Nega [=DenGasher=], with all the modes of the orignal.

[[folder: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 [[KidFromTheFuture 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.

* [[AmazinglyEmbarrassingParents Amazingly Embarassing Grandfather]]: Ryotaro, though Kotaro later drops the attitude.
* BreakTheHaughty: Momotaros has a talk with Kotaro that makes him more understanding of his supposedly "weak" grandfather.
* CatchPhrase: "My strength is *snaps fingers twice* the real thing.".
* CharacterTics: 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!"
* DistressedDude: His capture is an important part of ''Onigashima Battleship''.
** HostageForMcGuffin
* EmbarrassingFirstName: He dislikes it because apparently in the future it gained the connotation of being a "country" name.
* FinishingMove
** Strike Form
*** ''Counter Slash'': A DiagonalCut with the [=MacheTeddy=].
*** ''Strike Spurt'': New Den-O's Rider Kick.
** Vega Form: ''Brandish Dive''
* [[KidFromTheFuture Grandkid 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.
* LamarckWasRight: He seems to have inherited Ryotaro's ''bad luck'' of all things...
* PowersViaPossession: Averted with Strike Form, but played straight with Vega Form needing Deneb to possess Kotaro.
* RealLifeWritesThePlot: 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.
* RearrangeTheSong: Double-Action Strike Form (rock and roll), finally introduced in the ''Chou Den-O Trilogy''.
* WeaponOfChoice:
** MorphWeapon: Kotaro has the power to change any Imagin into a weapon for him to use.
*** [[{{BFS}} Big]] [[MacheteMayhem Machete]]: [=MacheTeddy=]
*** AnAxeToGrind: Kintaono (Kintaros in ''Episode Blue'')
*** EpicFlail: Uratazao (Urataros in ''Episode Blue'')
*** CoolSword: Momotaken (Momotaros in ''Let's Go Kamen Rider'')
** SwissArmyWeapon: Like his Grandpa, Kotaro has his own [=DenGasher=] that can be assembled in any mode.
*** BladeOnAStick: Naginata Mode (Vega Form, when Deneb possesses him in ''Onigashima Battleship'')
*** CoolSword: Sword Mode (Strike Form, when Teddy is fighting alongside him)

----

!!Teddy/Neotaros (voiced by Creator/DaisukeOno; 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.

* BattleButler
* EmpathicWeapon: Teddy can transform into New Den-O's weapon, the [=MacheTeddy=].
* MeaningfulRename: 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.
* [[OnlySaneMan Only Sane Imagin]]: A down-to-earth kinda guy, especially when compared to the other Imagin.
* StealthPun: 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.
* TalkingWeapon: His [=MacheTeddy=] form.
* WeaponTombstone: [[spoiler: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 TimeCapsule buried underneath.]]

----

!!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.

* AffablyEvil: 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.
* AfterlifeExpress: The Ghost Train, a spectral steam engine with a skull mounted on the face, somewhat reminiscent of ''VideoGame/FinalFantasyVI'''s Doomtrain.
* FinishingMove: ''Terminate Flash''
* LoveMakesYouEvil: He's so blinded by his mission, that he fails to realize that Sora never wanted him to do it.
* {{Necromancer}}
** GangOfHats: Fitting in with this ability, Shiro's Imagin minions are associated with darkness (Ghost, Phantom, Shadow).
* PaletteSwap: 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 [[RedRightHand mechanical gauntlet]].
* WeaponOfChoice
** BattleTops: ''Exploding'' toy tops.
** {{BFS}}: [=SavageGasher=]; It's made up of [[http://kamenrider.wikia.com/wiki/File:Den-O-Yuuki-hijack.jpg two complete DenGasher sets]].
** WhipItGood
* WoobieDestroyerOfWorlds: Has a tragic backstory.

* CityMouse

* PrecociousCrush: 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 that she reminded him of his deceased mother. TheOtherWiki mentions that she is Yu's mother's ancestor.
* TheStinger: [[spoiler: Yu is revealed at the end as a younger Yuto Sakurai through a MeaningfulEcho 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.

* TakingTheBullet: She took a hit meant for Yu, leaving her injured.

----

!! Kuchihiko[=/=]Goldra (portrayed by Eisuke Sasai)
* BerserkButton: Did ''not'' take his brother's death well.
* BlingBlingBang
* EvenEvilHasLovedOnes: The two oni, despite being time-traveling conquerors, genuinely care for each other, and Goldra goes ''berserk'' when he's killed.
* FailedASpotCheck: For RuleOfFunny. He didn't see Teddy standing ''right in front of him'' when he was riding the [=DenLiner=].
* LastVillainStand: 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.
* VillainousBreakdown: Goes ''completely'' berserk when his brother's killed.

* WouldHurtAChild: Even though Yuu only stumbled upon them by accident, Mimihiko decides to kill him for no other reason than [[ForTheEvulz he's bored]].

!!Reiji Kurosaki[=/=]Kamen Rider G Den-O (portrayed by Yuta Furukawa, suit actor Norihito Itō)

A member of the [[TimePolice G-Men]], Kurosaki uses the artificial Imagin Eve to protect the timestream as Kamen Rider G Den-O. He initially appears chasing [[Series/KamenRiderDecade Daiki Kaitou/Kamen Rider [=DiEnd=]]], who was attempting to cause a TimeParadox 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.

* [[spoiler:AIIsACrapshoot: His artificial Doberman Pinscher Imagin, Eve, is a KnightTemplar.]]
* [[spoiler:AxCrazy: Eve doesn't take Kurosaki's HeelFaceTurn very well...]]
* AwesomenessByAnalysis: 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. [[spoiler: When Eve takes over as G Den-O and goes AxCrazy, he begins doing this on his own.]]
* BlingBlingBang: Out of his Rider form, his main weapon is an elaborate gold revolver, which Daiki attempted to steal in 2008.
* FinishingMove: Although not mentioned in the movie, the Gun Mode's finisher is called World Punish, and the [[CarryABigStick Jutte Mode]]'s is called World End.
* GenderBlenderName: Eve.
* [[spoiler:HeelFaceTurn: 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 AxCrazy...]]
* [[spoiler:HeelRealization: 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 HeelFaceTurn.]]
* InspectorJavert: 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.
* [[spoiler:KillAllHumans: After Reiji pulls a HeelFaceTurn, Eve goes AxCrazy and decides this is the best way to police time.]]
* KnightTemplar
* MeaningfulEcho: When arresting Daiki, he repeats a line that Daiki said to him two years ago, which is what lets Urataros figure out what's going on.
* MissingMom: [[spoiler:And the letters in the box with the golden gun are from her, which is part of the reason Daiki went back to "redo" the theft.]]
* [[spoiler:RasputinianDeath: After Eve goes AxCrazy and becomes G Den-O itself, Reiji gives [=DiEnd=] a K-Touch to become [[SuperMode DiEnd Complete Form]].
