!!Tsukasa Kadoya/Kamen Rider [[color:magenta:Decade]]

A mediocre photographer with no memory of his past.

* TheAce: He's good at everything - except ''taking pictures''.
* AllThereInTheManual: A couple of books have shown cards that were made but never used, including Form Rides for Den-O Rod, Gun, and Wing, and another Attack Ride for Den-O Ax. [[note]]''Utchari'', a Sumo lifting strike[[/note]]
* AttackReflector: The [[spoiler:''Goseiger: Reflecloud'' Gosei Card-slash-]]Attack Ride card in ''Super Hero Taisen''.
* AtTheCrossroads: Tsukasa spends the series [[WalkingTheEarth Walking The Worlds]], and Decade has multiple 'crossing lines' motifs - the two lines on his chest, the fact that the kanji for 'ten' is 十, and the Roman numeral for ten is X. He is constantly at the crossroads, in between worlds, always traveling.
* BunnyEarsLawyer
* CameraFiend
* {{Catchphrase}}: "[[IWasJustPassingThrough I'm just a passing Kamen Rider]]. Remember that!" [[note]]''Tōrisugari no Kamen Raidā da, oboeteoke!''[[/note]]
* DeadpanSnarker: Note his reaction to Natsumi being framed for murder. While Yuusuke is horrified, he just goes "She's finally done it."
* DemotedToExtra: Despite having the specific role of PlanarChampion, his appearance in ''[[Film/OOODenOAllRidersLetsGoKamenRiders Let's Go Kamen Riders]]'' have him as FakeShemp. Averted with ''[[Film/KamenRiderXSuperSentaiSuperHeroTaisen Kamen Rider Super Sentai: Super Hero Taisen]]'', where he's one of the two main characters (his counterpart being [[Series/KaizokuSentaiGokaiger Captain Marvelous/Gokai Red]]).
** Played straight again in ''[[Film/KamenRiderXSuperSentaiXSpaceSheriffSuperHeroTaisenZ Kamen Rider Super Sentai Space Sheriff: Super Hero Taisen Z]]'', where Decade makes a cameo as part of a gathering of Riders and Sentai (his FakeShemp is [[Series/TokumeiSentaiGobusters Red Buster]] [[Main/ActingForTwo this time]]). Inverted in the [[Main/PostScriptSeason post script two-parter]] of ''[[Series/KamenRiderWizard Kamen Rider Wizard]]'', where Tsukasa is the only one of the previous 13 Heisei Riders to appear in the flesh alongside Haruto and one of only two to be portrayed by his original actor.
* DoppelgangerAttack: The ''Decade: Illusion'' Attack Ride card.
* [[spoiler: EvilCostumeSwitch: Decade [[SpellMyNameWithAnS Violent Emotion/Fury Form]] is a bit more subtle about it, with the main suit being a slightly darker magenta and the helmet having a purple O-Signal (instead of yellow) and vaguely flame-shaped eyes.]]
* [[spoiler: FaceHeelTurn: Three times! In ''All Riders vs. Daishocker'', he becomes Daishocker's Great Leader, in the final episode and ''Movie Wars'' he finally accepts his role as the Destroyer, and in ''Superhero Wars'' he becomes the Great Leader once more and, along with Captain Marvelous, instigates the war between Riders and Rangers.]]
** [[spoiler: That last one would actually be a case of GoodAllAlong, since he and Marvelous were setting everything up in a BatmanGambit so they could take out all of Dai-Shocker and Dai-Zangyack at once with the combined powers of every single Franchise/KamenRider and SuperSentai in existence.]]
** [[spoiler: Another GoodAllAlong in the final episode of ''Wizard''. He is summoned by Amadum to take the [[Series/KamenRiderFourze]] Rider Ring to complete Amadum's collection, seemingly betraying Haruto when he forces him to give him the Ring. Amadum summons the Riders to kill Haruto when he intrudes in his lair, wrongly believing they would obey him because he possesses the Rings, only to learn that Kamen Riders not only fight for justice but human freedom.]]
* FinishingMove: Because Decade can transform into past Riders, he can also use their finishing attacks.
** When using his own Final Attack Ride card, his finishers all involve generating large golden Final Attack Rider cards that Decade goes through to destroy the enemy.
*** ''Dimension Kick''
*** ''Dimension Slash''
*** ''Dimension Blast''
** Decade Complete Form: ''Enhanced Dimension Kick'' [[note]]The ''Climax Heroes'' fighting game shows an alternate version where the opponent is transported to a projection of the Rider Multiverse and instead of cards, Decade leaps through the emblems of the nine previous Riders (with Decade's emblem appearing behind the enemy to hold them in place).[[/note]]
** Final Form Ride finishers
*** Kuuga Gouram: ''Decade Assault'' [[note]]Kuuga Gouram grabs the enemy and flies them towards Decade, who executes his own version of the Mighty Kick.[[/note]]
*** Kiva Arrow: ''Decade Fang'' [[note]]The Kiva Arrow's tip opens a'la Kiva's Hell's Gate and Decade fires a red energy arrow with the power of the Darkness Moon Break.[[/note]]
*** Ryuki Dragredder: ''Decade Dragoon'' [[note]]Decade, with Ryuki Dragredder's assistance, performs Ryuki's Dragon Rider Kick.[[/note]]
*** Blade Blade: ''Decade Edge'' [[note]]The Blade Blade charges with lightning and Decade releases a SwordBeam like Blade King Form's Royal Straight Flush.[[/note]]
*** Faiz Blaster: ''Decade Photon'' [[note]]Decade traps the enemy with an energy drill like Faiz's Crimson Smash, then fires a giant beam from the Faiz Blaster.[[/note]]
*** Agito Tornador: ''Decade Tornado'' [[note]]Agito Tornador grows an energy ram resembling Agito's Cross Horn emblem and charges through the enemy.[[/note]]
*** Momotaros: ''Decade Liner'' [[note]]Momotaros performs a version of the Extreme Slash; the one time it's used, the [=DenGasher=]'s blade sticks into Kuuga Gouram's "butt" and Momo uses it as a giant bludgeon.[[/note]] [[note]]The arcade game ''Ganbaride'' gives Decade his own version of this, in which four-color doppelgangers of Decade ride energy rails and attack the enemy in a fashion reminiscent of Den-O Liner Form's four different Train Slash attacks before the real Decade finishes them off with his version of the Fullthrottle Break.[[/note]]
*** Zecter Kabuto: ''Decade Meteor'' [[note]]Zecter Kabuto rams the enemy high into the sky, the lands and transforms back into Kabuto; he and Decade then perform their respective Rider Kicks while in Clock Up.[[/note]]
*** Hibiki Ongekiko: ''Decade Wave'' [[note]]Hibiki Akanetaka rams the enemy before turning into a giant Taiko; Decade then uses it to perform a version of Hibiki's finishers.[[/note]]
*** Double [[color:green:[=CycloneCyclone=]]] and [[color:purple:Joker]][[color:purple:Joker]]: ''Triple Extreme'' [[note]]The three Riders perform their own version of Double's Joker Extreme.[[/note]]
* GuileHero: Oh yes, he knows how to thinkg with more than the cards in his hand. [[spoiler: He's manipulated the entire multiverse to against him to save it in the final episodes of his series, and in the later moves such as Wizard's finale and Superhero Wars, he joined the bad guys for the sake of them revealing their hands and gathering all the Riders together in order to beat them.]]
* [[spoiler: HeelFaceTurn: Former head of Dai-Shocker, turned amnesiac hero... turned head of Dai-Shocker again... turned hero for real. In ''Superhero Wars'' he's GoodAllAlong and just waiting for the bad guys to reveal their secret weapon. GoodAllAlong again in the last episode of ''Wizard'', completing Amadum's 13 Rider Ring collection so he can summon them all just so they can reveal that they don't serve him.]]
* [[spoiler: HeelFaceRevolvingDoor: The last few episodes see this happen to Tsukasa. Though ultimately good, he has to become whatever the Kamen Riders need to be in order to finish their stories and save the multiverse. Everything from [[BigGood the hero who helps the Riders unleash their true powers]] to the [[BigBad the villain who unites said heroes against him]], he's accepted his fate. He's gone from bad to good in several movies as well, though he was GoodAllAlong those times.]]
* TheHero
* IncrediblyLamePun: Decade's movie-exclusive form in the first ''Movie Wars'' is called [[spoiler:Gekijōtai (Violent Emotion). The Japanese word for a movie is Gekijō''ban''.]]
* {{Invisibility}}: ''Decade: Invisible''
* JerkassWithAHeartOfGold: Often acts like this to other Riders in order to save their worlds. Most seen in Blade's world, where he acts like an arrogant ladder-climber in order to unravel the Undead conspiracy and get the Blade cards revealed.
* LaserGuidedAmnesia: He remembers many things about the worlds he visits, but can't recall his own past.
* MadeOfIron: The ''Blade: Metal'' Attack Ride card.
* MultiformBalance
** JackOfAllStats: Decade Form, as well as all 9 of the previous Rider's main forms.
** FragileSpeedster: Kuuga Dragon, Agito Storm, Faiz Axel and Kiva Garulu.
** GlassCannon: Kuuga Pegasus and Kiva Basshaa.
** MightyGlacier: Kuuga Titan, Den-O Ax and Kiva Dogga.
** StoneWall: Agito Flame
** SuperMode: Complete Form, which lets him summon the super modes of his predecessors and copy their finishing moves. [[spoiler: When the nine AR Riders are actually present, it sends all of them straight into their most powerful forms so they can finish off Doras together.]]
* [[spoiler:MultiversalConqueror: As Great Leader of Dai Shocker, pre-amnesia and during part of the ''All Riders vs. Dai Shocker'' film.]]
* PhraseCatcher: "Damn you! Who are you?!" [[note]]''Kisama! Nani mono nanda?!''[[/note]]
* PlanarChampion: The role he takes as Decade. [[spoiler:Then he finds out that it was the wrong idea. ''Superhero Wars'' offers a twisted version, where he re-forms Daishocker in order to protect the Kamen Rider universe from Captain Marvelous and Daizangyack.]]
* PowerCopying: His entire theme, being able to transform into any of the nine previous Heisei Rider heroes.
** Then it gets turned UpToEleven in Super Hero Taisen as we get hints that Decade can turn into any and all Riders when we see him after he's turned into ''Ichigo'', and seems to be able to do the voices of whoever he's turned into as well as using their powers and abilities.
* [[RealMenWearPink Real Men Wear]] [[InsistentTerminology Magenta]]: He wants to be very clear that it's not pink.
* [[ShesGotLegs He's Got Legs]]: As several fans have noted, his live-actor Masahiro Inoue is very tall, and most of that height comes from his legs. Watch him get off the Machine Decader sometime.
* TheSpock
* [[spoiler:SuicideByCop: In ''Movie Wars'', he allows Natsumi to kill him after he defeated all the other Riders, as his actions meant that the Kamen Rider multiverse would exist forever.]]
* SummonMagic: The ''Ryuki: Advent'' Attack Ride card.
* SuperSpeed: The ''Kabuto: Clock Up'' and ''Blade: Mach'' Attack Ride cards. Also, Faiz Axel by default.
* SureLetsGoWithThat: Early on, whenever Yuusuke claims to the Kamen Rider of the Week that Tsukasa was only being a {{Jerkass}} to teach them something, Tsukasa gets a look on his face of "uh, yes, that was why".
* TomatoInTheMirror: [[spoiler:He was the Great Leader of Dai-Shocker.]]
* TransformingMecha: The ''Faiz: Autovajin'' and ''Kaixa: Side Basshar'' Attack Ride cards.
* {{Troll}}: He has no problem openly stating that he wants to get in on Kaito's treasure hunt, sometimes without clear reason. [[spoiler:This will bite him back later on when it is Kaito's turn to get in Tsukasa's way during battle for Apollo Geist's Perfecter.]]
* UndeadTaxExemption: Every time he enters a parallel world, he's assigned a role that helps him solve the current crisis, such as being a policeman in Kuuga's World or a lawyer in Ryuki's. [[spoiler:Given a tragic twist in ''Movie Wars'', where Wataru Kurenai says that since Decade's job is to be whatever the multiverse needs, he has no "real" role and therefore no home, meaning that there's supposedly no way to bring him back when he dies.]]
* WeaponOfChoice
** SwissArmyWeapon: The Ride Booker holds Decade's cards and can turn into a [[CoolSword sword]] or a [[{{Handguns}} gun]].
** DualWielding: The ''Hibiki: Ongekibou Rekka'' Attack Ride card.
** KillItWithFire: The ''Ryuki: Strike Vent'' and ''Hibiki: Onibi'' Attack Ride cards.
** ShapeshifterWeapon: When using the Final Form Ride cards, Decade can transform a Rider into either a weapon, vehicle or sentient creature for him to use:
*** {{BFG}}: Faiz Blaster
*** {{BFS}}: Blade Blade
*** HoverBoard: Agito Tornador
*** InstantAwesomeJustAddDragons: Ryuki Dragredder
*** InstrumentOfMurder: Hibiki Ongekiko (a phoenix that folds into a giant drum)
*** MiniMecha: Kuuga Gorgum and Zecter Kabuto.
*** TheStraightAndArrowPath: Kiva Arrow

!!Natsumi Hikari[[spoiler:/Kamen Rider Kivala]]

In spite of her terrifying dream, Natsumi refuses to believe Narutaki's ranting about Decade being a "destroyer of worlds". No-one she can keep in line with her family's pressure point technique could end up becoming a murderer of Riders...right?

* [[spoiler: ActionGirl]]
* AffectionateNickname: Tsukasa often calls her "Natsumikan" ("summer mandarin orange" in Japanese).
* [[spoiler:CoolSword: Kivala Saber]]
* [[spoiler: {{Deconstruction}}: Of the Female Rider Death Curse until the appearance of [[Series/KamenRiderGaim Kamen Rider Marika]].]]
* DemonicPossession: Body-jacked by three of the main Imagins in Den-O's world.
* {{Deuteragonist}}
* DistressedDamsel
* DreamingOfThingsToCome
* FingerPokeOfDoom: The Hikari Secret Laughing Pressure Point, which she mostly uses on Tsukasa when he does or says something rude. [[spoiler: Weaponised during the big movie war fight.]]
* [[spoiler:FinishingMove: ''Sonic Stab'']]
* TheKirk
* TakingTheBullet: Steps in the way of Apollo Geist's life-draining beam for Tsukasa...a matter of minutes after he insisted that they weren't [[TrueCompanions comrades.]]
* [[spoiler: TookALevelInBadass]]
* {{Tsundere}}
* ZettaiRyouiki

!!Yuusuke Onodera[=/=]Series/KamenRiderKuuga

An AlternateUniverse incarnation of the 1st Heisei era Kamen Rider, established in 2000. He tends not to get involved in fight scenes as much as Tsukasa and Kaitou, but is easily the friendliest and most approachable member of the team (to the point that Tsukasa snarks it's the only thing he's good for).

* BrainwashedAndCrazy: Three times over the course of the series[[note]]''All Riders vs. Daishocker'', World of Diend, and ''Movie Wars''[[/note]], though in the second case it's more like Brainwashed and Mellow.
* ButtMonkey
* FinishingMove: Same as the original.
* ForHappiness: As with Godai, his motivation is to protect everyone's smiles.
* TheHeart
* TheMcCoy
* MultiformBalance: Possesses '''[[color:red:Mighty]]''', '''[[color:blue:Dragon]]''', '''[[color:green:Pegasus]]''', '''[[color:purple:Titan]]''', and '''[[color:gray:Growing]]''' forms just like the original. He never achieves '''[[color:gold:Rising]]''' or '''Amazing Mighty''', but has one form Godai never did: ([[spoiler:'''Rising Ultimate''']]).
* MythologyGag: In ''All Riders vs. Daishocker'', he gives his predecessor's trademark thumbs-up to Tsukasa before his match with Amazon.
* WeaponOfChoice: Again, the same ones as the original.
** BareFistedMonk: '''[[color:red:Mighty]]'''
** CoolSword: '''[[color:purple:Titan]]'''
** BlowGun: '''[[color:green:Pegasus]]'''
** SimpleStaff: '''[[color:blue:Dragon]]'''

!!Eijiro Hikari[[spoiler:/Doctor Shinigami]]

Natsumi's Grandfather, who owns and runs the dimension-hopping photo studio. He's harmless enough, but it's unclear just how aware he is of the bizarre superhero adventures going on around him, especially after we learn that [[spoiler: he's Doctor Shinigami...sort of.]]

* CoolOldGuy: Though he's not as active as others, he's the unflappable foundation of the Hikari Studio. He's also an excellent cook, preparing all sorts of fun treats, particularly cookies that look like the group during the Shinkenger arc.
* DisneyDeath: [[spoiler: He shows up after the fight with Dai-Shocker, apparently back to his old self with no memory of what happened.]]
* HeelFaceTurn: [[spoiler: ''Movie Wars'' suggests he was brainwashed into being Shinigami in the first place, and he clearly no longer wants any part of it. He's drafted into Super-Shocker by his own ''cape'', and we see a [[Series/KamenRiderDouble Shinigami Gaia Memory]] being destroyed when Natsumi rescues him.]]
* [[spoiler:LivingWithTheVillain]]
* ParentalSubstitute: Natsumi's flashbacks show that she's been living with Eijiro since she was a child.
* WeirdnessCensor: Absolutely '''nothing''' fazes this man. His reaction to the Spider Fangire and Sieg coming into the studio? Take their pictures; after all, they're customers.

!![[color:gray:Kivala]]

A mini-Kivat from the World of Kiva. She appears to be working with Narutaki at first, but gradually drifts towards the good guys [[spoiler: and transforms Natsumi into a Kamen Rider during the final movie.]]

* AllThereInTheManual: Backstory info reveals that she's Kivat the 3rd's little sister.
* AlternateReality: Obviously, but in the ''S.I.C. Hero Saga'' story for ''Kiva'', she shows up during Nago and Megumi's wedding to warn them about the Lion Fangire's spirit becoming a giant Sabbat [[spoiler:and lets Megumi transform into Kamen Rider Kivala]].
* KissOfTheVampire: [[spoiler:Unlike Kivat, it doesn't cause a transformation. And when she does it on Narutaki...let's just say his face suggests [[DoesThisRemindYouOfAnything something more pleasant]].]]
* TeamPet
* TheDragon: To Narutaki....''very'' briefly.
* TokenEvilTeammate: When she first follows the Hikari's, the show makes no effort to hide that she has an agenda of her own. At a few points, [[spoiler:[[TheMole she even exchanges information with Narutaki, the closest thing to an Arch-Enemy Decade has.]]]] By the series' end however, [[HeelFaceTurn she shows a good side]] and reveals [[spoiler: that her actions were only helping Tsukasa and the Hikaris the whole time.]]
* TransformationTrinket: [[spoiler: For Natsumi.]]

An alternate universe of the 5th Heisei era Kamen Rider, established in 2004.

!!!Kazuma Kendate
An alternate version of Kamen Rider Blade. Kazuma is a Rank Ace employee of the BOARD corporation and kind of a smug jerk. However, he gets demoted in the course of Decade's passing through his world, but later regains his confidence and learns what it truly means to be a Rider.
* AccidentalMisnaming: Tends to call Tsukasa "cheese" rather than "chief".
* AscendedMeme: This is a reference to the "Ondul" meme associated with original ''Blade'' star Takayuki Tsubaki and his occasionally slurred-by-emotion pronunciations.
* BreakTheHaughty
* MeaningfulName: Kendate can be split into "ken", blade, and "date", where the kanji used means rouse; thus, he is the blade rouser.

An alternate version of Kamen Rider Leangle. Mutsuki is a Rank King employee of the BOARD corporation.
* JerkassFacade: Pretends to be a jerk to Kazuma in order to teach him some humility.
* MeaningfulName: Kuroba sounds very similar to the English word "clover".
* {{Salaryman}}

An alternate universe of the 4th Heisei era Kamen Rider, established in 2003.

* WolfMan

!!!Shouichi Ashikawa
An alternate version of Kamen Rider Agito.
* CompositeCharacter: He began as the user of the G3-X suit, until his transformations into Exceed Gills led to him abandoning the G3 team. Later his transformation stabilizes and he becomes Agito. Thus he is all three ''Agito'' Riders, though not simultaneously.
* ItsNotYouItsMyEnemies: He ran away from the police because his evolution into Exceed Gills was attracting the Lords' attention and he didn't want Yashiro getting hurt.
* MeaningfulName: He has the given name of the original Agito ('''Shouichi''' Tsugami), and his family name is a mix of that of Gills' and G3's (Ryou '''Ashi'''hara and Makoto Hi'''kawa''').

!![[Series/KamenRiderDenO World of Den-O]]
The world of the 8th Heisei era Kamen Rider, established in 2007. Unlike other universes, this seems to be the original Den-O universe ''and'' the PoorlyDisguisedPilot for the ''Chou Den-O'' movies, so information about the characters can be found on [[Characters/KamenRiderDenO that show's Character page]].

!![[Series/KamenRiderKabuto World of Kabuto]]

!!!Souji

[[/folder]]

[[folder: Other characters]]
!!Narutaki[[spoiler:/Colonel Zol/Doctor G]]

A guy in a hat and coat who follows the group around, pitting enemies against them and ranting about how everything is Decade's fault. That's about it.
* ArchEnemy: Appears consistently enough to be this to Decade.
* BigGood: Claims to be [[BlatantLies a friend to all riders]] in the [[Series/KamenRiderGaim Gaim]]/[[Series/ResshaSentaiTokkyuger ToQGer]] crossover. Granted, none of the people he spoke to knew about his role in Decade...
* TheCameo/DeusExMachina: Briefly makes an appearance in the [[Series/KamenRiderGaim Gaim]]/[[Series/ResshaSentaiTokkyuger ToQGer]] crossover to give [[Series/KamenRiderGaim Kouta]] a [[Series/ResshaSentaiTokkyuger Rainbow Pass]].
* CassandraTruth: He travels the multiverse warning people that Decade is going to destroy them all. Since Tsukasa is trying to help people, it looks like it's just bluster. [[spoiler:Subverted: Tsukasa ''is'' going to destroy the multiverse, but that's actually a good thing.]]
* TheInfiltration: A villainous example. Narutaki does this in ''Decade: Last Story''; [[spoiler: posing as Colonel Zol in order to further Eijiro's brainwashing as Doctor Shinigami.]] Seems to reveal him as the real thing at first, until he [[BaitandSwitch reverts back to his normal form after the penultimate battle.]] This implies that [[spoiler: the real Zol was either absent or has been long dead.]]
** Decade himself [[LampshadeHanging lampshades Narutaki's actions prior to the aforementioned battle.]]
--> '''Tsukasa''': Narutaki! Do you want to see Decade defeated so badly that you even became a Shocker?
* {{Catchphrase}}: '''"[[JapanesePronouns ONORE Decade!]]"'''
* EnemySummoner: He's no threat to any of the main characters physically, so he either summons Riders / monsters to fight for him or convinces people that Decade's a threat.
* EvilLaugh
* FaceHeelRevolvingDoor
* HiddenDepths: If the [[Series/KamenRiderGaim Gaim]]/[[Series/ResshaSentaiTokkyuger ToQGer]] crossover is anything to go by, it would seem he's more than willing to assist riders who (presumably) aren't associated with Decade. On top of that, he's apparently a regular on the [[Series/ResshaSentaiTokkyuger Rainbow Line]].
* LargeHam
* MysteriousBenefactor: In the [[Series/KamenRiderGaim Gaim]]/[[Series/ResshaSentaiTokkyuger ToQGer]] crossover, [[TheCameo he briefly drops by]] to give [[Series/KamenRiderGaim Kouta]] a Rainbow Pass, claiming to be [[BlatantLies a friend to all riders]].
* NiceHat
* [[spoiler:OneWingedAngel: He transforms into [[Series/KamenRiderV3 Crab Laser]] during the final battle]] in ''Super Hero Taisen''.
* TheUnfettered: Narutaki is completely dedicated to opposing Decade in every sense. [[BlueandOrangeMorality Good and Evil don't seem to apply to his actions.]] He's shown both good and evil traits throughout his run,{[[spoiler: showing concern for Natsumi during the series; reinforcing Eijiro's brainwashing as Shinigami, etc.}]] but isn't fighting for either side. (Though he usually finds himself working with other villains, as they have their own reasons for hating Decade) He'd probably be TheRival if it wasn't for Diend.
* {{Troll}}: Narutaki's goals are never explored, nor are they achieved if ''Last Story'' is anything to go by. So right now, he's probably [[ForTheEvulz just screwing with Decade for the sake of screwing with him]]. Supported by his role in ''Super Hero Taisen''.
* [[spoiler:TheUnfought]]: Until ''Super Hero Taisen'', anyways.
* [[spoiler:VoluntaryShapeshifting: Seems to be the case. So far he's transformed Colonel Zol and Doctor G, as well as Doctor G's Crab Laser form.]]

!!Daiki Kaito/Kamen Rider Diend

The second original Rider for the series, a dimension-hopping thief who looks out for no-one but himself (at first, anyway). [[spoiler: He comes from a world ruled by monsters who brainwashed the population, including his own brother.]]

* TheAtoner
* BarrierWarrior: ''Diend: Barrier''
* BigBrotherMentor: Becomes this to Asumu, who [[MoralityPet brings out a nicer side of him]].
* CombinationAttack: The ''Diend: Crossattack'' Attack Ride card lets two summoned Riders do this.
* DoppelgangerAttack: The ''Diend: Illusion'' Attack Ride card.
* EnemySummoner
* EvenEvilHasStandards: Detests those who take the freedom of others, and is willing to bail out Tsukasa and co. if he feels he owes them.
* EvilCannotComprehendGood: At first. He assumes that the "greater treasure" Tsukasa was talking about in Faiz's world was a better Rider belt, and doesn't get why Tsukasa is so bent on getting Geist's Perfecter and saving "Natsumelon".
* FinishingMove: ''Dimension Shoot''
** ''Blue Strike'': His Rider Kick.
** Diend Complete Form: ''Enhanced Dimension Shoot''
** Diend has also done some finishers with Final Form Rides.
*** Kiva Arrow: ''Diend Fang''
*** Blade Blade: ''Diend Edge''
* HeelFaceTurn
* {{Invisibility}}: ''Diend: Invisible''
* {{Irony}}: He loves poking at Tsukasa's distaste for sea cucumber, but the live shows have a RunningGag where eating sea cucumber causes Diend to flip out and start shooting up the place.
* ItMustBeMine
* MeaningfulName
* MythologyGag: The treasures he stole from the various worlds were originally items exclusive to that series' movie (the Orga Gear, the G4 microchip, et cetera). [[spoiler:This makes a kind of psuedo-sense when you consider that Kaito himself is from a world based on a movie continuity, Kamen Rider Blade's ''Missing Ace'' movie]]. This gets dropped quite quickly, but his obsession with movie continuities comes back with his Complete Form, which features movie-exclusive Riders.
* TheOnlyOneAllowedToDefeatYou: He claims this is why he goes along with Tsukasa for the final fight with Apollo Geist.
* PhantomThief
* TheRival
* [[SixthRanger Second Rider]]
* SuperMode: Diend gets his very own Complete Form during the events of ''Cho Den-O Trilogy: Episode Yellow''. As a movie-exclusive form, it summons an entire team of movie-exclusive Riders and [[ThereIsNoKillLikeOverkill lets him use all their finishers at once.]]
* SuperSpeed: When using the Tesla Bands on his wrists.
* {{Troll}}: Pretty much uses it as an artform.
* WeaponOfChoice
** {{Handguns}}: Diendriver, which also functions as his TransformationTrinket.
** ShapeshifterWeapon: Diend has used some Final Form Ride cards of his own.
*** {{BFS}}: Blade Blade
*** TheStraightAndArrowPath: Kiva Arrow
