Tsukasa Kadoya/Kamen Rider Decade

Tsukasa Kadoya/Kamen Rider Decade

Portrayed by: Masahiro Inoue (live), Seiji Takaiwa (suit)

"I'm just a passing through Kamen Rider, remember that."

A mediocre photographer with no memory of his past.

Tropes that apply to him in general

• The Ace: He's good at everything - except taking pictures. That and being courteous in general, much to his friends' chagrin.
• Amnesiac Hero: Used to be one, until he regained his memories in Kamen Rider Decade: All Riders vs. Dai-Shocker and learned he's the leader of Dai-Shocker.
• 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.
• Beware the Superman: His very existence is feared around the AR Worlds, to the point that every residing AR World Rider revile him as the "Devil". This is due to the fact that Tsukasa had a history with Dai-Shocker, and was originally its Great Leader. Matters not helped by the fact that he is called the "Destroyer of Worlds".
• Bunny-Ears Lawyer: There is almost nothing he doesn't excel at, but his way doing expressing this tends to come across as... eccentric.
• Camera Fiend: Keeps his camera with him at all times, though most pictures he takes don't come out that good.
• Character Catchphrase: Has a few of them to boot.
  • "I'm just a passing-through Kamen Rider. Remember that!"^note Tōrisugari no Kamen Raidā da, oboeteoke!; an alternate translation (seen on the Bluray box cover) is "I'm just a stranger called Kamen Rider."
  • Less commonly, he says "I get the gist of it."^note Daitai wakatta. after someone explains things to him.
  • Last but definitely not the least, "This might tickle" or some variations of it. He says this to most of the Kamen Riders he's going to use his Final Form Ride card on.
    • Hilariously, in the final part of Movie War 2010, various Riders line up in a single-file and borrows this catchphrase in sequence when transforming each other into their Final Form Rides.
• Celebrity Paradox: Apparently GARO is a thing where Tsukasa and Yusuke have been. The problem is that both he and one of GARO's villains are both played by Masahiro Inoue.
• Character Tics: Sometimes runs his hand across his sword.
• Contrasting Sequel Main Character: Both Tsukasa and Ryo Murasame/Kamen Rider ZX are the 10th rider of their respective eras. Ryo is the younger brother of Shizuka who was captured by the Badan Empire and turned into their cyborg before his brainwashing was undo due to a certain accident and used his newfound powers to fight the Badan and avenge the death of his sister by their hands, while Tsukasa is the older brother of Sayo who was originally the Great Leader of Dai-Shocker who receives the Decadriver to become a Kamen Rider before he becomes amnesiac and a hero who wants to save the multiverse and opposing Dai-Shocker. Moreover, while Ryo teams up with his predecessors from the Showa era in the main universe, Tsukasa teams up with various alternate universe versions of past Kamen Riders during his journey throughout the multiverse.
• 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).
  • Played straight again in 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 Fake Shemp is Red Buster this time). Inverted in the post script two-parter of 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.
  • Kamen Rider Taisen averts this - while the movie mostly focuses on Takeshi Hongo/Kamen Rider Ichigo and Kouta Kazuraba/Kamen Rider Gaim, Decade plays a major role in the movie, fighting alongside Kouta (both against the Showa Riders and against Badan).
• Destroyer Deity: Well, his title as "Destroyer of Worlds" is there for a reason, no?
• Dimensional Traveler: As Kamen Rider Decade, Tsukasa has the power to travel around multiple Kamen Rider universes.
• Dub Personality Change: The English dub removed a good chunk of Tsukasa's abrasive attitude. If anything, his personality is sometimes more close to The Everyman than a Jerkass with a Heart of Gold.
• 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. As Kamen Rider Decade however, he's pretty much the Heisei Rider version of Kamen Rider ZX.
• Face–Heel Turn: Three times! In All Riders vs. Dai-Shocker, he becomes Dai-Shocker'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.
• Fallen Hero: After accepting his fated role as the Destroyer of Worlds, Tsukasa becomes Kamen Rider Decade Violent Emotion, a dark, twisted transformation of his default rider form, whose purpose is to kill every Kamen Riders in sight. He loses this role after he was revived as a hero once again by his allies.
• 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 Taisen, he joined the bad guys for the sake of them revealing their hands and gathering all the Riders together in order to beat them.
• Greater-Scope Villain: He's the original Great Leader of Dai-Shocker and the one who began their plan to conquer the A.R. Worlds, only to lose his memory and become a hero instead, making him this to himself.
• 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.
• Iconic Sequel Character: Largely from his popularity and abilities as Decade, Tsukasa has made several appearances in sequels. Kamen Rider Zi-O not only brought him back, but made him a full-on main character directly involved in the story's conflict.
• Identical Stranger: To the alternate Shigeru Jo, which is why it's so easy for Tsukasa's role to be a Replacement Goldfish for him after a particularly nasty Face–Heel Turn.
• Image Song: Ride The Wind
• Insistent Terminology: In the net movies for All Riders vs. Dai-Shocker, 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.
  • In the world of Kuuga, he's given a cop's uniform.
  • In Kiva's world, he's a violinist.
  • In Ryuki's world, he's a lawyer.
  • In the world of Blade, he's an employee of BOARD.
  • In Faiz's world, he's a student of Smart Brain High School.
  • In Agito's world, he's a mailman.
  • In Den-O's world, he's given the clothes of the older Sakurai Yuto.
  • In the world of Kabuto, he's a ZECT trooper.
  • In Hibiki's world, he's given a kimono.
  • In the World of Negatives, he's given an luxury suit.
  • In Diend's world, he's a businessman.
  • In the world of the Super Sentai, he's a Kuroko.
  • In the worlds of Black RX and Black, he looks like Joe the Haze.
  • In the world of OOO, he looks like Ankh.
  • In the world of Stronger, he's a Replacement Goldfish for Shigeru Jo after the latter went off the deep end and becomes leader for the alternate Delza Army.
• Jerk with a Heart of Gold: Often acts like this to others. Best 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.
• Mike Nelson, Destroyer of Worlds: Oh boy, where to begin? He's literally called the "Destroyer of Worlds" and is believed to be a (metaphorical) demon bent on wiping out the multiverse. When our hero Tsukasa is given Decade's powers and tasked with destroying the Alternate Rider Worlds by the originals, he chooses instead to help those worlds' heroes with whatever crisis is going on when he arrives. It seems to work, until the final episode, where the originals tell him he's actually accelerating the destruction and try to kill him. This leads Tsukasa to Face–Heel Turn and destroy the Riders before committing Suicide by Cop. This turns out to be the right thing to do, since it gives the Rider Worlds "immortality" by ensuring that their stories will be told forever, and brings back all the worlds destroyed earlier.
• Multiversal Conqueror: As the Great Leader of Dai-Shocker, pre-amnesia and during part of the All Riders vs. Dai-Shocker film.
• Phrase Catcher: "You bastard! Who are you?!"^note Kisama! Nani mono nanda?!
• Real Men Wear Magenta: He wants to be very clear that it's not pink.
• Rule of Symbolism: According to Word of God, Tsukasa's poor photography skills are demonstrative of his inability to express his love for the world.
• 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.
• Smug Super: Natch.
• 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.
• 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.
• Worf Effect: Believe it or not, even Tsukasa can go through this. Heck, in Kamen Rider Zi-O, he is outright defeated by Swartz, Another Zi-O, and Ohma Zi-O, the latter easily overpowering Tsukasa's Decade Complete 21 Form.

Tropes exclusive to him as Kamen Rider Decade

Kamen Ride: Decade!

• 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 Utchari, a Sumo lifting strike
• Attack Reflector: The Goseiger: Reflecloud Gosei Card-slash-Attack Ride card in Super Hero Taisen.
• Doppelgänger Attack: The Decade: Illusion Attack Ride card.
• 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 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).
  • 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.
    • 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.
    • Ryuki Dragreder: Decade Dragoon^note Decade, with Ryuki Dragredder's assistance, performs Ryuki's Dragon Rider Kick.
    • Blade Blade: Decade Edge^note The Blade Blade charges with lightning and Decade releases a Sword Beam like Blade King Form's Royal Straight Flush.
    • 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.
    • Agito Tornador: Decade Tornado^note Agito Tornador grows an energy ram resembling Agito's Cross Horn emblem and charges through the enemy.
    • 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 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.
    • 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.
    • 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.
    • Double CycloneCyclone and JokerJoker: Triple Extreme^note The three Riders perform their own version of Double's Joker Extreme.
• Invisibility: Decade: Invisible
• Joke Item: The Ore Sanjou!, Bokuni Tsurarete Miru?, Nakerude!, and Kotaewa Kiite Nai Attack Ride cards. At best, they're glorified Form Ride cards but as Attack Rides, all they do is have Tsukasa say the four Imagins' catchphrases.
• Made of Iron: The Blade: Metal Attack Ride card.
• Multiform Balance: More so than any other Rider, since he can turn into any Rider he has the card for.
• Power Copying: His entire theme, being able to transform into any of the nine previous Heisei Rider heroes.
  • In Super Hero Taisen, he transforms into Ichigo, somehow perfectly mimicking his voice and appearance.
  • In Zi-O, we see him transform into primary Riders who come after him via the Neo Decadriver, such as Ghost and Build.
• Stealth Pun: In Movie Wars 2010 Decade receives a new form called Gekijoutai (激情体)^note Which is officially translated as "Violent Emotion" but can also be rendered as "Rage Form"; Gekijouban (劇場版) means "Movie Version", usually referring to a movie based off of a TV series.
• Summon Magic: The Ryuki: Advent Attack Ride card lets him summon Dragreder like the real Ryuki.
• Super Mode: Complete Form, which lets him summon the super modes of his predecessors and copy their finishing moves. When the nine A.R. Riders are actually present, it sends all of them straight into their most powerful forms so they can finish off Doras together.
• Super-Speed: The Kabuto: Clock Up and Blade: Mach Attack Ride cards. Also, Faiz Axel by default.
• Transforming Mecha: The Faiz: Autovajin and Kaixa: Side Basshar Attack Ride cards.

Natsumi Hikari

Natsumi Hikari/Kamen Rider Kiva-la

Portrayed by: Kanna Moriya (live), Yuuki Ono (suit)

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?

Tropes that apply to her in general

• Affectionate Nickname: Tsukasa often calls her "Natsumikan" ("summer mandarin orange" in Japanese), while Kaito calls her "Natsumelon".
• Chekhov's Gag: Her Affectionate Nickname "Natsumikan" pays off years after the series's original conclusion when she pays a visit to an AR World based on Kamen Rider Gaim, becoming a new version of Gaim based on the natsumikan fruit after replacing the world's Kouta Kazuraba.
• Demonic Possession: Body-jacked by three of the main Imagins in Den-O's world.
• Deuteragonist: She's the character with the third most significance in the story and since Yusuke is technically a Call-Back tribute character and not an original rider she's the series' true Tertiary Rider.
• Disposable Woman: Averted. Natsumi is the first non-temporary female Rider to avoid the "Female Rider Death Curse". Her survival starts a stint of no female Rider deaths until both Marika and Idunn^note Jam doesn't count since the girl that became Jam is possessed by Kougane died in Gaim.
• Damsel in Distress: A good chunk of Decade's plots can be summed up as "Natsumi got Kidnapped/is in trouble again."
• Depending on the Writer: Despite usually being a nice person, Natsumi can actually be quite selfish at times. Notably, when Tsukasa tried to warn her about the Nega World, she dismisses him in a pretty cruel manner. Even worse, she never apologizes for it afterwards.
• Dreaming of Things to Come: The series starts with her dreaming of the Rider War.
• Finger Poke of Doom: The Hikari Secret Laughing Pressure Point, which she mostly uses on Tsukasa when he does or says something rude. Weaponized during the big movie war fight.
• Finishing Move: Sonic Stab
• Ms. Fanservice: After being possessed by Urataros, she gets an outfit that's less than modest.
• Taking the Bullet: Steps in the way of Apollo Geist's life-draining beam for Tsukasa...a matter of minutes after he insisted that they weren't comrades.
• Ungrateful Bitch: Pretty downplayed, but she can be this way towards Tsukasa at times. Notably, despite constantly forcing him to risk his life as Decade, Natsumi expects him to pay full price for any services done by the Hikari Studio.

Tropes exclusive to her as Kamen Rider Kiva-la

^Spoilers

• Action Girl: After becoming Kamen Rider Kivala she makes short work of Tsukasa as Decade, and in the World of Gaim, she takes on what would've been the AR Kouta's role as, well, Gaim.
• Cool Sword: Kiva-la Saber.
• Combo Platter Powers: By definition in the World of OOO novel, as she is now both Kivala and Gaim Natsumikan Arms, complementing the alternate Eiji's similar case with Legend Tatoba and its fusion of three completely unrelated Riders for the sake of a "Taka, Tora, Batta" joke.
• Took a Level in Badass: Doesn't get much higher a level-up than becoming the Rider that stops Decade Violent Emotion. Breaking the streak of female Rider deaths also helps. The World of OOO novel takes it a step further when she gains a second, completely unrelated Rider identity in the form of Gaim Natsumikan Arms, and uses that to fight with the reunited Decade team in the novel's climax along with the alternate Eiji Hino and his Legend Tatoba combo.

Yusuke Onodera/Kamen Rider Kuuga

Yusuke Onodera/Kamen Rider Kuuga

Portrayed by: Ryouta Murai (live), Kenji Tominaga (suit)

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 Kaito, 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).

---

• Adaptational Dumbass: He is basically Godai if he's more childish and less talented than his original counterpart.
• Brainwashed and Crazy: Three times over the course of the series^note All Riders vs. Dai-Shocker, World of Diend, and Movie Wars, though in the second case it's more like Brainwashed and Mellow.
• The Bus Came Back: While Tsukasa and Kaito have returned many times throughout the franchise, Yusuke took over a decade to return from his last appearnce in Movie War 2010 to Rider Time Decade vs Zi-O.
• Butt-Monkey: Poor, poor Yusuke is nowhere near The Ace that his canon counterpart is. This also means that he lacks the power to control Ultimate Kuuga without external help.
• Finishing Move: Same as the original.
• For Happiness: As with Godai, his motivation is to protect everyone's smiles.
• The Heart: Just like the original Yusuke, he loves everything.
• Informed Ability: His abilities as Kuuga are nowhere near as impressive as the original. It's so bad that even in Ultimate Form and its upgraded forms, Yusuke frequently suffers from the Worf Effect
• Multiform Balance: Possesses Mighty, Dragon, Pegasus, Titan, and Growing forms just like the original. He never achieves Rising or Amazing Mighty, but has one form Godai never did: (Rising Ultimate).
• Mythology Gag: In All Riders vs. Dai-Shocker, he gives his predecessor's trademark thumbs-up to Tsukasa before his match with Amazon.
• Shock and Awe: The S.I.C. Hero Saga reveals that Rising Ultimate can be supercharged even further by various sources of electricity, enabling Yusuke to unlock Super Rising Ultimate by using Stronger's powers and OOO Shauta Combo's Unagi Whip to create a ridiculously-overpowered thunder-based form.
• Took a Level in Badass: For starters, he achieves a form beyond Ultimate Form.. S.I.C. Hero Saga takes it even further by having him attain Super Rising Ultimate.
• Weapon Specialization: Like the original Kuuga, some of his forms provide a unique weapon. For Titan, it's a purple Cool Sword. For Pegasus, it's a Blow Gun. For Dragon, it's a blue staff.

Eijiro Hikari

Eijiro Hikari/(Super) Doctor Shinigami

Portrayed by: Renji Ishibashi

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.
• Death by Adaptation: The manga version of All Riders vs. Dai-Shocker was played more seriously, with the reveal even seriously upsetting Natsumi. After Doctor Shinigami was destroyed in that version, Eijiro didn't return.
• 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: Turns out Natsumi's father was Dr. Shinigami all along.
• 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. The fact that he's seemingly an amnesiac Doctor Shinigami might help.

Kiva-la

Kiva-la

Portrayed by: Miyuki Sawashiro (voice)

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.

---

• All There in the Manual: Backstory info reveals that she's Kivat the 3rd's little sister.
• Alternate Universe: 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 and lets Megumi transform into Kamen Rider Kiva-la.
• Kiss of the Vampire: Unlike Kivat, it doesn't cause a transformation. And when she does it on Narutaki...let's just say his face suggests something more pleasant.
• Team Pet
• The Dragon: To Narutaki....very briefly.
• Token Evil Teammate: 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, she even exchanges information with Narutaki, the closest thing to an Arch-Enemy Decade has. By the series' end however, she shows a good side and reveals that her actions were only helping Tsukasa and the Hikaris the whole time.
• Transformation Trinket: For Natsumi.

Daiki Kaito/Kamen Rider Diend

Daiki Kaito/Kamen Rider Diend

Portrayed by: Kimito Totani (live), Eitoku (suit)

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.

Tropes that apply to him in general

• Ambiguously Gay:
  • The writing certainly seems to imply that he's attracted to Tsukasa; his own actor Kimito Totani has stated that Daiki is gay and "likes Tsukasa".
  • Kaito's actions in Super Hero Taisen, particularly after The Reveal, make a lot more sense if you assume he has feelings for Tsukasa: he outright says "You hurt me so I'll hurt you back", and after being defeated he testily tells Tsukasa "I never want to see you again...but I'm sure I'll never forget you."
• Big Brother Mentor: Becomes this to Asumu, who brings out a nicer side of him.
• Even Evil Has Standards: Detests those who take the freedom of others, and is willing to bail out Tsukasa and co. if he feels he owes them.
• Evil Cannot Comprehend Good: 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".
• Heel–Face Revolving Door: Which side he's on seems to depend on a), what his intentions are, b), who he owes, and c), which side can help him get what he's after if he wants something.
• Irony: He loves poking at Tsukasa's distaste for sea cucumber, but the live shows have a Running Gag where eating sea cucumber causes Diend to flip out and start shooting up the place.
• Image Song: Treasure Sniper
• It Must Be Mine!: His possesive nature would probably top even a Greeed.
• Jerkass: His self centered greed means that he completely doesn't take the feelings of people he hurts with his thefts into account and has to be flat out blackmailed into returning stolen property. At his worst, he is even willing to endanger children for selfish purposes.
  • Jerk with a Heart of Gold: Not as much as Tsukasa, but he has his moments. Cho Den-O Trilogy: Episode Yellow in particular has Daiki hijack the DenLiner so he can re-do a botched theft, not solely for selfish reasons, but because he accidentally destroyed another man's treasure (letters that his mother left behind before she died) in the process and felt remorseful.
• Meaningful Name: His surname can be translated as 'thief'.
• Mythology Gag: The treasures he stole from the various worlds were originally items exclusive to that series' movie (the Orga Gear, the G4 microchip, et cetera). 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.
• The Only One Allowed to Defeat You: He claims this is why he goes along with Tsukasa for the final fight with Apollo Geist
• Phantom Thief: Mostly because his taking treasures out of their home dimension making him unable to be found. He's actually pretty blunt when it comes to his treasure hunting.
• The Rival: He's oddly obsessed with Tsukasa, even to the point of possessiveness.
• Troll: Elevates it to an art form.

Tropes exclusive to him as Kamen Rider Diend

Kamen Ride: Diend!

• Barrier Warrior: Diend: Barrier
• Combination Attack: The Diend: Crossattack Attack Ride card lets two summoned Riders do this.
• Detect Evil: If the Diendriver falls into the hands of someone else who then attempts to transform with it, the voice and interface on the gun will distort if they happen to be evil, as demonstrated with Chinomanako.
• Doppelgänger Attack: The Diend: Illusion Attack Ride card.
• Enemy Summoner: His Diendriver allows him to summon holographic Riders to fight for him.
• Finishing Move: 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.
• Invisibility: Diend: Invisible
• Mook Maker: Summons copies of Kamen Riders (good, evil, and otherwise) to aid him in battle using his own deck of Rider Cards.
  • Also plays the trope straight once, summoning the Riotroopers from Kamen Rider 555.
• Super Mode: 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^note Kuuga and Den-O are the only Heisei series not represented; the former having never received a summer movie, and the latter due to the events of said movie locking said rider (Gaoh) out of the timestream (in-universe)/the suit being recycled for Yuuki's suit (real life) and lets him use all their finishers at once.
• Super-Speed: When using the Tesla Bands on his wrists.
• Weapon Specialization: Diend's signature weapon is the Diendriver, a gun that also functions as his Transformation Trinket.

---

• Dragons Up the Yin Yang: As with the original Ryuki.
• Meaningful Name: "tatsu" means dragon.

Portrayed by: Eiki Kitamura

An alternate version of Kamen Rider Knight. Ren was once Shinji's partner until he mysteriously left the Atashi Journal.

---

• Bat Out of Hell: As with the original Knight.
• 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.

Kamen Rider Scissors

Kazuma Kendate

Portrayed by: Hiroki Suzuki

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: The arc seems to be tailor made to hammer it in to him that he's not as awesome as he thinks he is.
• Meaningful Name: Kendate can be split into "ken", blade, and "date", where the kanji used means rouse; thus, he is the blade rouser.
• Salaryman: As with all the other AR Blade Riders, being a Rider is his job.

Sakuya Hishigata

Portrayed by: Yoshihiko Narimatsu

An alternate version of Kamen Rider Garren. Sayuka is a Rank Ace senior employee of the BOARD corporation.

---

• Hidden Heart of Gold: Pretends to be a jerk to Kazuma in order to teach him some humility.
• Meaningful Name: Hishigata means "diamond shape".
• Salaryman: As with all the other AR Blade Riders, being a rider is his job.
• 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

Portrayed by: Kazuma Kawahara

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 Kamijo for being Leangle and Shiori Hirose for being a technology support unit.
• Hidden Heart of Gold: 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: As with all the other AR Blade Riders, being a rider is his job.
• 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.

Hajime Shijo

Portrayed by: Ruo

An alternate version of Kamen Rider Chalice. Hajime is the president of the BOARD corporation.

---

• All Your Powers Combined: Absorbs Garren's and Leangle's life force in order to create the Black Joker.
• Ascended Extra: In a sense - in all crossovers since the end of Decade that feature both the Joker Undead and Chalice, he's present as the former, since the original Hajime is always Chalice.
• Arc Villain: Of the World of Blade.
• Composite Character: Apart from being Hajime Aikawa's AR version in the World of Blade, he also has spades of both Isaka and Hiroshi Tennoji, having the former's acquisition of having people sacrificed in a secret lab for his ambitions while being an (inconspicuously) evil CEO who uses a special Rouse Card to transform like the latter.
• Corrupt Corporate Executive: Not only did he and Kamata have Sakuya and Mutsuki sacrificed to make the Joker card, but he also made it very clear to Kazuma that having Undeads unsealed and resealed would make great business profits and publicity for him.
• Four Is Death
• Greed: One reason for his villainy.
• Meaningful Name: The "shi" in his name means "four", referring to his being the fourth Rider of his world.
• No Good Deed Goes Unpunished: A small, but villainous example: Despite Hajime's slight Benevolent Boss interactions with him, Tsukasa ultimately repays him in the end by calling him out on his greedy nature while siding with Kazuma to defeat him and Kamata.
• One-Winged Angel: As the Joker. Contrast with the original series, where the Joker was Hajime's true form.
• Villain with Good Publicity: None of the people that worked for him that aren't Riders knew of his evil nature, seeing him as a respectable, esteemed president of theirs.

---

• Demoted to Extra: He's the only of the AR Riders not to make even a token cameo in Movie Wars 2010.
• Hunter of His Own Kind
• Meaningful Name: Ogami means "wolf", punning off of the original Takumi's surname Inui, which means "dog".
• Ordinary High-School Student: Subverted; whilst Takumi's seemingly just an ordinary student, he's also the Wolf Orphnoch.
• Wolf Man

Yuri Tomoda

Portrayed by: Yurie Midori

---

• Suspiciously Similar Substitute: Is Mari Sonoda's World of Faiz equivalent.

Momose

Portrayed by: Ryosuke Miura

The Tiger Orphnoch who leads this world's version of the Lucky Clover.

---

• Arc Villain: Of the World of Faiz.

• Panthera Awesome: His animal motif.

Akekawa

Portrayed by: Ayasa Hanagata

The World of Faiz's Lobster Orphnoch.

• The Smurfette Principle: Like Saeko, she's also the sole female of her group.

Genda

Portrayed by: CHIKARA

The World of Faiz's Dragon Orphnoch.

---

• The Brute: Of his group.
• Jerk Jock: Going by his role in the group and aggressive appearance.
• A Lighter Shade of Black: A small one, but he lacks the selfishly sociopathic impulses that Kitazaki had.

Shirogane

Portrayed by: Takuya Nagaoka

The World of Faiz's Centipede Orphnoch.

---

• Evil Genius: Going by his glasses and a few of his shown mannerisms.
• The Stoic: Is usually more emotionless when compared to Takuma.
• We Hardly Knew Ye: Only lasted one episode, all just to show off Diend's proper debut.

World of Agito

World of Agito

An alternate universe of the 2nd Heisei era Kamen Rider, established in 2001.

Shouichi Ashikawa

Portrayed by: Satoshi Yamanaka

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

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.

World of Kabuto

An alternate universe of the 7th Heisei era Kamen Rider, established in 2006.

---

Sohji

Portrayed by: Daijiro Kawaoka

An alternate version of Kamen Rider Kabuto.

---

• The Ace: Unlike most other A.R. Riders, Sohji is this. He can even best Kaito/Diend in seconds, the latter using two copy Riders specifically to track Kabuto's Clock Up movement.
• Adaptational Badass: Believe it or not, Sohji is arguably this towards Soji Tendo, A.K.A the original Kabuto. To note, whereas Tendo was initially defeated by The Bee and his own Worm doppleganger, Sohji bested both without any issue. Plus, Sohji can use the Perfect Zector's strongest attack with one hand, as opposed to two.
• Adaptational Nice Guy: Not that the original Kabuto isn't without moments of kindness, but he was definitely an Arrogant Kung-Fu Guy and pretty Innocently Insensitive at times. In contrast, Sohji has a much more mellow disposition.
• Big Brother Instinct: Goes out of his way to protect his sister Mayu, accepting her identity as a Worm without judgement.
• Earn Your Happy Ending: By "Movie War 2010", Sohji has been freed from his nightmarish imprisonment from Clock Up mode. He is even shown detransformed at one point.
• Heroic Willpower: Despite being stuck as Kabuto in Clock Up mode for countless years, Sohji continues to protect the innocent from Worms and Dai-Shocker. It's actually really amazing that he still retains his sanity.
• Power Incontinence: His Clock Up has malfunctioned, trapping him in a world beyond normal human perception. Luckily, it's fixed by "Movie War 2010".

Arata

Portrayed by: Tetsuya Makita

An alternate universe of the 6th Heisei era Kamen Rider, established in 2005.

---

Hibiki

Portrayed by: David Ito

An alternate version of Kamen Rider Hibiki.

---

• And Then John Was a Zombie: He eventually transformed into Gyuki because of his desire for power.
• Hidden Heart of Gold: As he secretly mutates into Gyuki, he acts standoffish and rude so his turning won't hurt those he cares about.
• Take Up My Sword:It turns out he's trying to steel Asumu to become the next Hibiki.

Asumu

Portrayed by: Kazuki Koshimizu

Hibiki's apprentice who eventually takes up his master's mantle as Kamen Rider Hibiki. Helps his friends Akira/Amaki and Todoroki reunite the three schools of Oni.

---

• Kid Hero: As in the original series.
• Legacy Character: Unlike his home series where his Oni suit was even stripped for parts to enhance Kyosuke's behind the scenes, Asumu becomes the second Kamen Rider Hibiki.
• Morality Pet: Served as one to Daiki/Diend.

Ibuki

Portrayed by: Jouji Shibue

An alternate version of Kamen Rider Ibuki (though played by the same guy), who is the master of the Ibuki school.

---

• Blow You Away: As with his canon counterpart.
• Slobs Versus Snobs: On the snobs end.

Akira/Amaki

Portrayed by: Eri Akiyama

An alternate version of Akira, Ibuki's apprentice. In Decade she becomes her own full-fledged Rider, Kamen Rider Amaki.

---

• The Gunslinger: As with her mentor, the Ongekikan: Reppu functions as one.
• Sailor Earth: In Hibiki she borrowed Ibuki's Transformation Trinket once and transformed into a technically unnamed Rider^note Officially called just "Akira Transformed State"; Decade makes her a full-fledged Oni Rider.

Zanki

Portrayed by: Kenji Matsuda

An alternate version of Kamen Rider Zanki (again, played by the same guy). Master of the Zanki school.

---

• Shock and Awe: As in canon.
• Slobs Versus Snobs: On the slobs end, comparatively.

Todoroki

Portrayed by: Shingo Kawaguchi

Zanki's apprentice.

---

• Ship Tease: Implied to have a thing for Akira/Amaki.

Other A.R. World Members

Even as Decade completes his journey through the nine worlds, there's still some trouble to be dealt with throughout the rest of The Multiverse.

---

World of Negatives

World of Negatives

A version of Natsumi's world set After the End in which a vile, sociopathic counterpart to Otoya Kurenai has taken over the world, with the past monsters and dark Riders evolving to be able to Kill and Replace their victims.

---

Otoya Kurenai/Kamen Rider Dark Kiva

Portrayed by: Kouhei Takeda

The Evil Overlord of the World of Negatives, a man who looks like Wataru Kurenai's father but is much, much worse than him.

---

• Ambiguous Situation: It's unclear if this Otoya is based on the original and went off the deep end somehow, a stand-in for Dark Kiva's previous user, or just another monster pretending to be him.
• Evil Overlord: Is more in line with King rather than Otoya as a character, going so far as to be the ruler of the World of Negatives.
• Evil Twin: One of the few A.R. World Riders to be a carbon copy of the actual past Rider, although this Otoya's personality is completely warped in comparison to the prime Otoya.
• Horrible Judge of Character: Manipulates Tsukasa into accepting the K-Touch so he can stay in the World of Negatives and join him as a Dark Rider. However, he turns right back around as Decade Complete and murders the three "teens" serving him, ultimately delivering comeuppance to Otoya himself.

"Hirohiko Sato"/Kamen Rider Ryuga

Portrayed by: Keisuke Sakamoto

An alternate version of Ryuga who murdered and assumed the identity of one of Natsumi's classmates from the TG Club.

---

• Cruel and Unusual Death: Subjected to a double cross sword slash from Decade Complete and Ryuki Survive, killing Dragblacker in the process and burning Ryuga to death. As painful as this probably is seeing as how he's the only one of the "teens" to shriek in pain upon dying, whoever's pretending to be Hirohiko certainly deserved it.
• Mythology Gag: Transforms the same way Dark Shinji did, simply holding out his deck before placing it in the V-Buckle.
• Recruit Teenagers with Attitude: Subverted, Hirohiko is long dead and Ryuga is his true identity as a monster (either a Mirror Monster or Hirohiko's counterpart in the Mirror World) serving Otoya.
• Single-Stroke Battle: After Decade assumes Complete Form, Ryuga attempts to take him out with a single blow from his Final Vent. Decade and Ryuki Survive get the upper hand, however, as their double cross sword slash is enough to ensure Ryuga dies a painful, roasting-hot death.

"Kazuyoshi Aoyagi"/Kamen Rider Dark Kabuto

Portrayed by: Yohto Mori

An alternate version of Dark Kabuto who succeeded in his mission to Kill and Replace his target, this one being an old friend of Natsumi.

---

• The Bad Guy Wins: In the original Kabuto series, "Souji Kusakabe" initially harbored a desire to supplant the original Souji as Kabuto. The World of Negatives shows what would've happened if Dark Kabuto ("Kazuyoshi" in this case) won.
• Combat Pragmatist: The only Kabuto Rider in the entire franchise who canonically and deliberately bypasses Masked Form by pulling the horn on his Zecter before the armor can materialize.
• Curb-Stomp Battle: Attempts to off Decade with a Rider Kick, only for both him and Hyper Kabuto to strike back with much more force than what a copy of the basic Kabuto armor is capable of.
• Mythology Gag: Shares some traits with the original Dark Kabuto, notably his more sinister persona compared to the other dark Riders with him and the fact that he leers slightly before inserting the Dark Kabuto Zecter.
• Recruit Teenagers with Attitude: Subverted, Kazuyoshi is long dead and Dark Kabuto is his true identity as a monster (probably a Worm) serving Otoya.
• Slasher Smile: His face curls up into one just before the helmet of the Dark Kabuto armor forms.

"Kenji Sakata"/Kamen Rider Orga

Portrayed by: Keisuke Sakamoto

An alternate version of Orga who murdered and assumed the identity of one of Natsumi's friends.

---

• BFS: Like the alternate Yuji Kiba before him, he has access to the Orga Stlanzer which can grow to massive sizes for finishers. It shatters against the power of the Photon Buster and Ride Booker, unfortunately.
• Mythology Gag: Shares the alternate Kiba's lack of a proper transformation pose when transforming into Orga.
• Never Bring a Knife to a Gun Fight: Learns the hard way that no matter how big the Orga Stlanzer gets, it's no match for Faiz Blaster's Photon Buster and Decade Complete's Ride Booker overclocked to fire at roughly the former's output.
• One-Steve Limit: An interesting case, in which Kamen Rider Orga is the one subject to this trope in the series rather than the user(s). The main Emperor Belt from the World of Faiz was stolen before someone could christen themselves as Orga with it, leaving "Kenji" as the only A.R. Orga despite the potential to make more.
• Recruit Teenagers with Attitude: Subverted, Kenji is long dead and Orga is his true identity as a monster (probably an Orphnoch) serving Otoya.

World of Diend

World of Diend

Kaito's homeworld and an alternate version of Kamen Rider Blade: Missing Ace.

---

Junichi Kaito/Kamen Rider Glaive

Portrayed by: Yuki Kuroda

Daiki Kaito's older brother and an alternate version of Kamen Rider Glaive.

---

• Face–Heel Turn: Subverted. Originally a part of a trio with Haruka and Shin up until the incident with Kaito. However...
• Not Brainwashed: He later reveals he had been working under Fourteen all along from his own volition back then, as a way to catch rebels.

---

Haruka Miwa/Kamen Rider Larc and Shin Magaki/Kamen Rider Lance

Haruka Potrayed by: Yoko Mitsuya

Shin Portrayed by: Takao Sugiura

Junichi's teammates and alternate versions of Kamen Riders Larc and Lance.

---

• Adaptational Heroism: Both their Missing Ace counterparts are morally ambiguous Anti Heroes, while their versions in the World of Diend are straight-up heroic freedom fighters.

---

Kotaro Minami/Kamen Rider BLACK RX

Portrayed by: Tetsuo Kurata

---

• The Ace: Like his main counterpart, he is already a valiant and skilled warrior, with even Dai-Shocker's monsters bested by him.

---

Joe the Haze

Portrayed by: None

Kotaro's closest ally, who has been missing for a while before Hikari Studio entered this world.

---

• The Unseen: Despite being mentioned throughout two episodes
• I Choose to Stay: Ultimately decides to remain in the World of BLACK to help the other Kotaro deal with Gorgom.

World of BLACK

World of BLACK

World of Amazon

World of Amazon

An alternate version of Kamen Rider Amazon, where Dai-Shocker have allied with Gedon and taken over, forcing humanity to distrust each other and moreso any Rider.

---

Daisuke Yamamoto/Kamen Rider Amazon

Portrayed by: Enrique Sakamoto

An alternate version of the original Kotaro Minami who has kept on fighting along Joe the Haze against the Crisis Empire.

---

• Adaptational Intelligence: The original Daisuke started the series as a primitive tribe man that barely knew any Japanese words, meanwhile this Amazon has a better comprehension of Japan's culture. Justified given this Amazon has went to places like Europe and America already.
• No Name Given: His real name is never said during his appearances, only known from magazines.

---

Masahiko Okamura

Portrayed by: Akashi Takei

An alternate version of Amazon's child friend Masahiko, fiercely loyal to Dai-Shocker.

---

• Adaptational Angst Upgrade: The original Masahiko wasn't as emotionally struck by the death of his father, partly from having Amazon and the others as a Parental Substitute. This version only had his sister for support, thus serving Dai-Shocker to cope.
• Heel–Face Turn: Ultimately being almost killed by Dai-Shocker and realizing Amazon had trusted in him brings him closer to be like the original Masahiko.

World of OOO

World of OOO

An alternate version of the 12th Kamen Rider series, Kamen Rider OOO, separate from baseline reality. Things follow roughly the same course of events, at least until Tsukasa and Narutaki get involved, after which things get... strange.

---

Eiji Hino/Kamen Rider OOO

An alternate version of Eiji who seems to be much like his prime counterpart, until Tsukasa replaces his new friend Ankh (while Hina Izumi gets replaced by Narutaki) and takes him for one hell of a ride, one that involves Shocker, Yusuke Onodera, and... Kamen Riders Tiger and Habataki?

---

• Body Horror: Thought the other Final Form Rides were bad? Poor Eiji has to temporary undergo Literally Shattered Lives whenever he's subjected to one, as his entire body fractures apart into suit pieces to augment Decade.
• Combo Platter Powers: The only thing tying the seemingly-random assortment of Rider powers making up Legend Tatoba is that one's a hawk, another a tiger, and yet another a grasshopper, and otherwise have no real cohesion.
• Chekhov's Gunman: As OOO Shauta Combo, he is revealed to be a key component of unlocking Kuuga Super Rising Ultimate.
• Equippable Ally: His Final Form Ride turns him into a suit of armor to augment Decade's own suit.
• Literally Shattered Lives: A non-lethal example with his Final Form Ride, which fractures him into parts that make up a suit of armor for Decade.
• Visual Pun: Legend Tatoba is based on Kamen Riders Habataki (themed after a hawk), Tiger (themed after a tiger), and Ichigo (themed after a grasshopper). The OOO Driver processes the corresponding medals as "Taka, Tora, Batta" without any changes, being the Japanese translations of the above motifs.

World of Gaim

World of Gaim

An alternate version of the 15th Kamen Rider series, Kamen Rider Gaim, separate from baseline reality. While Tsukasa and Narutaki are busy taking the alternate Eiji on a rather bizarre escapade, Natsumi pays a visit to the World of Gaim alone. Like the World of OOO, this world is roughly parallel to the original TV series, and Natsumi arrives during what would've been #21 of Gaim proper. Unfortunately for everyone involved, things are about to get weirder as Kouta disappears and Natsumi comes across a blank Lockseed and Sengoku Driver that fit her perfectly...

---

Takatora Kureshima/Kamen Rider Zangetsu

An alternate version of Takatora who is similar to his prime counterpart, although his Rider form is slightly fancier.

---

• Shield Bash: Par for the course with Zangetsu's Melon Defender, but this incarnation has the extra benefit of also being a massive vice that can be used to grip and crush enemies.

Mitsuzane Kureshima/Kamen Rider Ryugen

Takatora's younger brother. Is largely unchanged from his prime counterpart, so refer to Mitsuzane's character page for more information. That being said...

---

• Foreshadowing: Tsukasa visiting this alternate counterpart of Micchy would hint towards him encountering the real Micchy by chance in Saver's void with the Dragon Fruits Energy Lockseed in Gaim's novel a few months later, directly leading to the creation of Ryugen Jimber Dragon Fruits.

Dai-Shocker

In General

An alternate version of Shocker comprised of monsters from all throughout the Showa and Heisei eras. They seek the conquest of the A.R. Worlds and are looking to accelerate the worlds merging.

---

• Legion of Doom: They bring together villains from the Showa era and the first nine Heisei era seasons, all in the name of interdimensional conquest.
  • Their army in the World of Decade seen in All Riders Vs. Dai-Shocker includes prominent Showa villains such as Ambassador Hell and General Jark and A.R. versions of High Priestess Bishium and Shadow Moon, as well as various Gurongi, Lords, Mirror Monsters, Orphnochs, Undead, Makamou, Worms, Imagin and Fangire.
  • In Kamen Rider × Super Sentai: Super Hero Taisen their army has expanded to include more prominent Rider villains including General Shadow, the real Shadow Moon, N-Daguva-Zeba, the Arch Orphnoch, Gryllus Worm and the Weather Dopant, while Dopants and Yummies join the ranks of the kaijin involved.
• Multiversal Conqueror: Their end goal is to conquer all of the A.R Worlds.
• Standard Evil Empire Hierarchy:
  • The Emperor: The Great Leader of Dai-Shocker.
  • The Right Hand: Shadow Moon, as well as High Priestess Bishium after he takes power.

  • The Oddball: Schwarian.

Apollo Geist

Guy/Apollo Geist

Portrayed by: Kazuhisa Kawahara (live), Shinichi Kaneda (suit)

"Apollo Change!"

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 Kaito, he doesn't last long enough to be part of Super Shocker.

---

• Big Bad: As Dai-Shocker starts to intervene more in the plot, Apollo Geist is the one spearheading their assault.
• Dragon-in-Chief: He's not the actual leader of Dai-Shocker, but he's their only eminent executive seen in the series who lasts for more than two episodes, and the one in charge of their A.R. World invasion, making him for all intents and purposes the main antagonist for the second half of the show.
• Hijacked by Ganon: As the major threat throughout most of Decade's endgame, he pulls off this trope given how he's a villain from a previous instalment.
• Immortality Immorality: He's able to survive indefinitely off the life force of others.
• Life Drain: As a side affect of being revived, he has to consume the life force of others in order to extend his own.
• Luckily, My Shield Will Protect Me: As with his X counterpart, Apollo Geist wields a giant shield.
• Original Generation: While Apollo Geist is an established character, in Decade he gains power from the Fangire and becomes Super Apollo Geist in the final arc.
• Super Mode: Gains the ability to become "Supr Apollo Geist" after he marries the Fangire Queen. He actually becomes powerful enough to overwhelm Decade Complete Form, Diend, Kuuga (A.R.), and Kiva (A.R.) all at once.
• Throwing Your Shield Always Works: Uses his shield as a weapon just as often as he uses it for defense.
• Unholy Matrimony: Marries Yuki the Fangire Queen to obtain Fangire powers, granting him a new Super Mode.

The butler of the Kadoya family, who took care of Sayo while Tsukasa was away, he is also a member of Dai-Shocker with the power to transform into Shadow Moon. Appears in the movie Kamen Rider Decade: All Riders vs. Dai-Shocker.

---

• Adaptational Villainy: The original Shadow Moon was a Tragic Villain who was forced to become evil by Gorgom. His Alternate Self acts entirely out of his own free will, being cruel towards Sayo without any hesitation.
• Battle Butler: Has the power to transform into Shadow Moon and easily defeats Decade and Kuuga Rising Ultimate (A.R.), though he winds up getting his ass kicked by Kamen Rider Double soon after.
• Big Bad: Of ''Kamen Rider Decade: All Riders vs. Dai-Shocker, once he takes over Dai-Shocker from Decade.
• The Chessmaster: Orchestrates the defeat of all the Kamen Riders in a battle royale to decide the strongest, right before revealing to Tsukasa his true nature so he can retake the throne of Dai-Shocker. And then usurping him.

• The Starscream: Usurps Tsukasa once he returns to lead Dai-Shocker.

Narutaki/Colonel Zol/Doctor G

Portrayed by: Tatsuhito Okuda

Onore Dikeido!^note Translation: Curse you, Decade!

A mysterious man 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.

---

• Arch-Enemy: Appears consistently enough to be this to Decade.
• Big Bad: Of Super Hero Taisen as Doctor G, along with Rider Hunter Silva.
• Big Good: Claims to be a friend to all Riders in the Gaim/ToQGer crossover. Granted, none of the people he spoke to knew about his role in Decade...
• The Cameo: Briefly makes an appearance in the Gaim/ToQGer crossover to give Kouta a Rainbow Pass.
• Cassandra Truth: 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. Subverted: Tsukasa is going to destroy the multiverse, but that's actually a good thing.
• Character Catchphrase: "Curse you, Decade!" ^note "Onore Dikeido!"
• Enemy Summoner: He is 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.
• Face–Heel Revolving Door: His alignment to himself doesn't really change, but Narutaki waffles quite a bit on his treatment of Tsukasa. Sometimes he's venomous enough to the Passing Through Kamen Rider to actively encourage him to die to protect the worlds and other times he acts more like a friendly Sitcom Arch-Nemesis. This also extends to Dai-Shocker and other Kamen Riders as a whole, many times he warns and helps other Riders to go against Tsukasa, but he's also both wanted to end Dai-Shocker and has joined them other times to destroy all Riders.
• The Heavy: He's Decade's only recurring foe for the first half of the series, and the man behind several threats.
• Hidden Agenda Villain: Who is he? Where did he come from? Why does he hate Decade so much? Don't expect this to ever be answered.
• Hidden Depths: If the Gaim/ToQGer crossover is anything to go by, it would seem he's more than willing to assist Riders who aren't working with Decade. On top of that, he's apparently a regular on the Rainbow Line. Kamen Rider Taisen also further suggests he seems to respect Riders in general, only saying his catchphrase to Decade so he can ask him why Kamen Riders are so awesome.
• The Infiltration: A villainous example. Narutaki does this in Decade: Last Story; 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 reverts back to his normal form after the penultimate battle. This implies that the real Zol was either absent or has been long dead.
  • Decade himself 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?
• Large Ham: Yep.
• Mysterious Benefactor: In the Gaim/ToQGer crossover, he briefly drops by to give Kouta a Rainbow Pass, claiming to be a friend to all riders.
• One-Winged Angel: He transforms into Crab Laser during the final battle in Super Hero Taisen.
• Poor Communication Kills: One potential reason for his treatment of Decade is the fact that he only knows Tsukasa as a Destroyer of Worlds without knowing quite what that means.
• The Unfettered: Narutaki is completely dedicated to opposing Decade in every sense. Good and Evil don't seem to apply to his actions. He's shown both good and evil traits throughout his run,{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 The Rival 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 just screwing with Decade for the sake of screwing with him. Supported by his role in Super Hero Taisen.
• The Unfought: Never fights Decade. Until Super Hero Taisen, anyways.
• Voluntary Shapeshifting: Seems to be the case. So far he's transformed into Colonel Zol and Doctor G, as well as Doctor G's Crab Laser form.
