Tsukasa Kadoya/Kamen Rider Decade

A mediocre photographer with no memory of his past.

  • The Ace: He's good at everything - except taking pictures.
  • All There in the Manual: 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 
  • Attack Reflector: The Goseiger: Reflecloud Gosei Card-slash-Attack Ride card in Super Hero Taisen.
  • At the Crossroads: Tsukasa spends the series 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.
  • Bunny-Ears Lawyer
  • Camera Fiend
  • Catchphrase: "I'm just a passing Kamen Rider. Remember that!"note 
  • Deadpan Snarker: Note his reaction to Natsumi being framed for murder. While Yusuke is horrified, he just goes "She's finally done it."
  • Demoted to Extra: His appearance in Let's Go Kamen Riders have him as Fake Shemp. Averted with Kamen Rider × Super Sentai: Super Hero Taisen, where he's one of the two main characters (his counterpart being Captain Marvelous/Gokai Red).
  • Doppelgänger Attack: The Decade: Illusion Attack Ride card.
  • Evil Costume Switch: Decade 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.
  • Expy: Tsukasa is The Ace, a Jerkass, and has a little sister, just like Souji Tendou - it's even lampshaded when Tsukasa ends up in Kabuto's World and seems to fit right in with Souji's grandmother and sister. You could compare his relationship with Yusuke to Souji Tendou's with Arata Kagami. Similarly, Tsukasa's whole life is about fighting other Riders and all his attacks are triggered by cards, much like Ryuki.
  • Face–Heel Turn: 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.
    • That last one would actually be a case of Good All Along, since he and Marvelous were setting everything up in a Batman Gambit so they could take out all of Dai-Shocker and Dai-Zangyack at once with the combined powers of every single Kamen Rider and Super Sentai in existence.
    • Another Good All Along in the final episode of Wizard. He is summoned by Amadum to take the Kamen Rider Fourze 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.
  • Finishing Move: 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 Kicknote 
    • Final Form Ride finishers
      • Kuuga Gouram: Decade Assaultnote 
      • Kiva Arrow: Decade Fangnote 
      • Ryuki Dragredder: Decade Dragoonnote 
      • Blade Blade: Decade Edgenote 
      • Faiz Blaster: Decade Photonnote 
      • Agito Tornador: Decade Tornadonote 
      • Momotaros: Decade Linernote  note 
      • Zecter Kabuto: Decade Meteornote 
      • Hibiki Ongekiko: Decade Wavenote 
      • Double CycloneCyclone and JokerJoker: Triple Extremenote 
  • Guile Hero: Oh yes, he knows how to think with more than the cards in his hand. 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.
  • Heel–Face Turn: Former head of Dai-Shocker, turned amnesiac hero... turned head of Dai-Shocker again... turned hero for real. In Superhero Wars he's Good All Along and just waiting for the bad guys to reveal their secret weapon. Good All Along 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.
  • Heel–Face Revolving Door: 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 the hero who helps the Riders unleash their true powers to the 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 Good All Along those times.
  • The Hero
  • Incredibly Lame Pun: Decade's movie-exclusive form in the first Movie Wars is called Gekijōtai (Violent Emotion). The Japanese word for a movie is Gekijōban.
  • Insistent Terminology: In the net movies for All Riders vs. Daishocker, Narutako mockingly refers to Decade as pink, which Tsukasa angrily protests — it's magenta, thank you very much!
  • Instant Costume Change: Every time he enters a new world, he gains new clothes and tools to fit his role in said world.
  • Invisibility: Decade: Invisible
  • Jerk with a Heart of Gold: 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.
  • Laser-Guided Amnesia: He remembers many things about the worlds he visits, but can't recall his own past.
  • Made of Iron: The Blade: Metal Attack Ride card.
  • Multiversal Conqueror: As Great Leader of Dai Shocker, pre-amnesia and during part of the All Riders vs. Dai Shocker film.
  • Phrase Catcher: "Damn you! Who are you?!"note 
  • Power Copying: His entire theme, being able to transform into any of the nine previous Heisei Rider heroes.
    • Then it gets turned Up to Eleven 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.
  • Real Men Wear Magenta: He wants to be very clear that it's not pink.
  • 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.
  • Suicide by Cop: 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.
  • Super Mode: Complete Form, which lets him summon the super modes of his predecessors and copy their finishing moves. 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.
  • Smug Super: Natch.
  • Super Speed: The Kabuto: Clock Up and Blade: Mach Attack Ride cards. Also, Faiz Axel by default.
  • Sure, Let's Go with That: Early on, whenever Yusuke 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".
  • Tomato in the Mirror: He was the Great Leader of Dai-Shocker.
  • Transforming Mecha: 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. 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.
  • Undead Tax Exemption: 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. 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.
  • Weapon of Choice

Natsumi Hikari/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?

Yusuke Onodera/Kamen Rider Kuuga

An Alternate Universe 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).

Eijiro Hikari/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 he's Doctor Shinigami...sort of.

  • Cool Old Guy: 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.
  • Disney Death: He shows up after the fight with Dai-Shocker, apparently back to his old self with no memory of what happened.
  • Heel–Face Turn: 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 Shinigami Gaia Memory being destroyed when Natsumi rescues him.
  • Living with the Villain
  • Parental Substitute: Natsumi's flashbacks show that she's been living with Eijiro since she was a child.
  • Weirdness Censor: 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.


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

     Riders of the Nine Worlds 
Alternate versions of the Riders from Kuuga to Kiva, except for Yusuke Onodera who accompanied Tsukasa in his journey.

World of Kiva

An alternate universe of the 9th Heisei era Kamen Rider, established in 2008.

An alternate version of Kamen Rider Knight. Ren was once Shinji's partner until he mysteriously left the Atashi Journal.
  • Bat out of Hell
  • Heroic Sacrifice: Non-lethal version: He managed to defeat the alternate Kamen Rider Odin and gain the Time Vent card, only for him to be too weak to use it.
  • Meaningful Name: Haguro means "black wings", referencing his Contract Monster Darkwing.
  • Not What It Looks Like: It looks to all the world that he's the one who killed Reiko, but he's actually trying to get Odin's Time Vent so he can prevent the murder to begin with.

World of Blade

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.
  • Accidental Misnaming: Tends to call Tsukasa "cheese" rather than "chief".
  • Ascended Meme: This is a reference to the "Ondul" meme associated with original Blade star Takayuki Tsubaki and his occasionally slurred-by-emotion pronunciations.
  • Break the Haughty
  • Meaningful Name: Kendate can be split into "ken", blade, and "date", where the kanji used means rouse; thus, he is the blade rouser.
  • Salaryman

Sakuya Hishigata

An alternate version of Kamen Rider Garren. Sayuka is a Rank Ace senior employee of the BOARD corporation.
  • Jerkass Façade: Pretends to be a jerk to Kazuma in order to teach him some humility.
  • Meaningful Name: Hishigata means "diamond shape".
  • Salaryman
  • What Happened to the Mouse?: When Garren shows up in the final arc, Kazuma only ever calls him by his Rider name, leaving it vague as to whether Sakuya survived Hajime's life-draining machine or if he died and this is a second Garren.

Mutsuki Kuroba

An alternate version of Kamen Rider Leangle. Mutsuki is a Rank King employee of the BOARD corporation.
  • Composite Character: He is a combination of Mutsuki Kamijou for being Leangle and Shiori Hirose for being a technology support unit.
  • Jerkass Façade: Pretends to be a jerk to Kazuma in order to teach him some humility.
  • Meaningful Name: Kuroba sounds very similar to the English word "clover".
  • Salaryman
  • What Happened to the Mouse?: When Leangle shows up in the final arc, Kazuma only ever calls him by his Rider name, leaving it vague as to whether Mutsuki survived Hajime's life-draining machine or if he died and this is a second Leangle.

Shouichi Ashikawa

An alternate version of Kamen Rider Agito.
  • Composite Character: 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.
  • It's Not You, It's My Enemies: 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.
  • Meaningful Name: 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 Ashihara and Makoto Hikawa).

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 Poorly Disguised Pilot for the Chou Den-O movies, so information about the characters can be found on that show's Character page.

     Other characters 

Narutaki/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.

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). He comes from a world ruled by monsters who brainwashed the population, including his own brother.

Kamata/Kamen Rider Abyss/Paradoxa Undead

An enigmatic man with the power of Kamen Rider Abyss, with Abysshammer and Abysslasher as his Contract Monsters. Revealed to be who killed the alternate version of Reiko Momoi, and thus the Big Bad of Ryuki World. However, after Decade and Ryuki defeat him, he is revealed to be the previously unseen Paradoxa Undead.

Apollo Geist

A representative of Dai Shocker, who extends his own dwindling lifespan by stealing the life-force of others. After Dai Shocker is crushed in All Riders, he marries the Fangire Queen to increase his powers and starts accelerating the collision of worlds. Thanks to Tsukasa and Kaitou, he doesn't last long enough to be part of Super Shocker.
