YMMV / Kamen Rider Decade

Go To

  • Awesome Music: Episode 19.
  • Best Known for the Fanservice: Most of Natsumi's fanart is her outfit from when she was possessed by Urataros. note .
  • Big-Lipped Alligator Moment: Double's appearance in All Riders vs. Dai-Shocker; he simply rides in, hands Shadow Moon his ass on a platter (after SM beat Decade AND Rising Ultimate Kuuga at the same time), sends him flying into the Dai-Shocker HQ, then rides off. However, the aftermath of the BLAM gives all Riders an extremely wide opening to perform the All Rider Kick.
    • It does later get a nod, however, in Movie Wars.
    • The Kabuto World story ends with Kivaara facing off with a Worm mimicking Kivaara, for no reason other than to have a Worm mimicking Kivaara. It gets weirder if you're familiar with the concept from the original series. note 
    • The first sign of Diend's powers shows up during a fight in Blade's world, where suddenly out of nowhere Todoroki appears. He plays his guitar solo, strikes his guitar into the ground attacking everyone, then disappears.

  • Broken Base: On one side, people who like Decade enjoy it because they feel it's a celebration of what makes Kamen Rider great while having an interesting Myth Arc story. On the other side, people who dislike it feel that the overuse of Suspiciously Similar Substitutes ruins what could have been a great Reunion Show and that every returning character was weakened to make Decade look strongernote . However, both sides generally agree that the show should have had more than two episodes per plot arc.

  • Cargo Ship: thanks to what happened to him in Diend world, Yusuke/Kivaala.
  • Complete Monster:
    • Momose/Tiger Orphnoch, the prideful leader of the new Lucky Clover in the World of Faiz, is introduced as a member of a gang of bullies studying at Smart Brain High School who is quickly revealed to be a budding psychopath. Having orchestrated a series of attacks targeting other students, Momose tries to kill Takumi's best friend in front of him and orders his comrades to indiscriminately kill numerous students while he could watch and mock the victims. Not satisfied with the initial massacre, Momose gathers the survivors in a circle for them to be executed one by one, informing them that if they are lucky, they could be turned into Orphnoch.
    • Otoya Kurenai/Kamen Rider Dark Kiva is King's substitute in the World of Negatives, possessing not only all of his Fantastic Racism, but also a charismatic personality to hide the fact that he is a cold-hearted, scheming dictator. Having created a law that qualifies humans as less than Riders, Otoya exterminated more than half of humanity in a genocide, and sends his minions to wipe out survivor camps. He also beats a Pseudo-Rider for defying him, commenting on how he must obey him for being a true Rider. Seeking to make Tsukasa his successor, Otoya tries to corrupt him into abandoning his journey and accepting the nature of his hateful world.
    • Kamen Rider Decade: All Riders vs. Dai-Shocker: Nobuhiko Tsukikage is a slimy member of Dai-Shocker who, through treachery and manipulation, became their new Great Leader. Acting as the seemingly loyal butler of the Kadoya family, Tsukikage's real identity is that of Shadow Moon from another reality where he lacks all of his original counterpart's sympathetic qualities. Keeping a close eye on Sayo Kadoya for possessing the source of Dai-Shocker's power, the Stone of the Earth, Tsukikage manipulates Tsukasa with the belief that he could stop the destruction of worlds by defeating the previous Riders, helping him in setting up the battle royal tournament, which doubles as a ritual to raise the Dai-Shocker Castle. After Tsukasa briefly resumes his role as the Great Leader of Dai-Shocker, Tsukikage takes advantage of Sayo's hatred towards her brother to organize a coup, swiftly overthrowing him to assume the throne for himself. Under his leadership, Dai-Shocker launches an ultimatum on the multiverse, ordering thousands of their own soldiers to perform kamikaze attacks and then releasing a legion of monsters to slaughter those who survived as part of their quest to assimilate all worlds into an interdimensional dictatorship.
  • Epileptic Trees: Not only is the typical life expectancy of female Riders subverted, but two female Riders (Akira in Hibiki and L'Arc in Blade) are brought back just to have them retconned with a much better fate. Unfortunately though in the Rider War...
    • And then the Final Chapter movie has Natsumi becoming Kamen Rider Kivara and they even give the original quasi-female Rider sidekick Tackle a decent sized sub plot as way of homage.
    • Though, Natsumi prior to being Kivara was Den-o for one episode, and was killed off a couple of episodes later. She gets better.
  • Harsher in Hindsight: in All Riders, Decade's Final Kamen Attack Ride has the All Riders turn into giant FFR cards. In Final Chapter, this is what remains of the Riders when Decade kills them. Subverted when it turns out that this is a good thing.
  • Hilarious in Hindsight: While this show features the first Super Sentai/Kamen Rider crossover, Mighty Morphin' Power Rangers and Masked Rider crossed over first. At the end of the Samurai Sentai Shinkenger crossover, the world of Kamen Rider BLACK RX, the show Masked Rider used footage from, is revealed to be the next world.
    • Speaking of Sentai, the first fight in the Shinkenger crossover with both Rangers and Riders involved Shinken Gold and Diend. Care to guess which Ranger is among the evil duplicates created by Diend's (outright villainous) Kaizoku Sentai Gokaiger expy Basco in his debut episode?
    • About Gokaiger again, though more subtly: the first Shinkenger episode of Decade was one of the very few times in Decade where the Kamen Rides (both Diend's and Decade's) had a thematic link to the episode's theme (Shinkenger, Ryuki and Den-O were all written by Yasuko Kobayashi); Gokaiger turned out to be far more liberal in its usage of such thematic transformations into past heroes in episodes with alumni guest stars.
    • In one of the Net Movies, Shin Kamen Rider imagines What Could Have Been if his show took off, like meeting up with a child fan - of Shin Kamen Rider. You know, FOR KIDS!
    • At the beginning of the Den-O World arc, everyone assumes that Den-O's Final Form Ride is supposed to be DenLiner since that's how the card shows it...then later on it's revealed to be Momotaros himself. And then in Final Chapter, the DenLiner thing becomes reality.
    • Another FFR example would be Agito's. Think they'll be using that concept again?
    • The appearance of King Dark near the end of All-Riders is funny in retrospect, since it means two personifications of the Great Leader note  are duking it out.
    • In the World of Hibiki, if you're an Oni and lose your sense of justice and seek only to be stronger, you turn into a Makamou. Change the words Oni and Makamou to Magical Girl and Witch respectively and you get what happens to Sayaka just a few years later.
      • Also replace the words justice and seeking to be stronger with sanity and refusing Grief Seeds respectively.
      • To make this one even better, the writer of the show went on to write Kamen Rider Gaim, in which Ryoji Hase goes insane and becomes an Invess.
    • Faiz's world is a High School A.U.. Which has Orphenoch hiding out in the school. Since they're zombies, does this count as a High School Of The Dead?
    • The Dark Riders story does this again. Natsumi used to be in this club of rejects, and they even get a loser teacher for their club advisor, just as the Kamen Rider Club did.
    • In Kamen Rider Ryuki, Shuichi Kitaoka/Zolda was a lawyer. In the World of Ryuki, they're all lawyers. Zolda earns an upgrade to public prosecutor, and is apparently a force to be reckoned with.
    • Let's see, we've got a character who summons heroes from other worlds via firing them out of a gun. Are we talking about Kamen Rider Diend or Kiran?
    • The 4th Kamen Rider, who only appears in a movie for the series, is played by the actor who sings the show's opening. Are you talking about Riderman being played by Gackt or Kamen Rider 4 being played by Mitsuru Matsuokanote ?
    • The MOTW of episode 24 becoming a monstrous version of Diend upon stealing the latter's Diendriver becomes this upon Kamen Rider Zi-O introducing the concept of the Another Riders, which are, you guessed it, also monstrous and corrupted versions of past Kamen Riders.
  • Just Here for Godzilla: Some people watch the series just because Black and Black RX are going to be in it with their original actor.
  • Memetic Loser: Yusuke Onodera has often been the butt of all jokes for his uselessness since he doesn't transform that much and when he does, he doesn't make any difference in fight scenes. He has been the measuring stick for how useless a character can be in a Kamen Rider show.
  • Memetic Mutation: "Mo' fear! Mo' pain! No henshin, Kamen Rider Kuuga!"note 
  • Memetic Troll:
    • Daiki Kaito/Kamen Rider Diend, he will give out vague information about Tsukasa to him, will switch sides midway because he’s bored, will steal something important and sometimes give it back at the last second, and can turn invisible and create duplicate illusions of himself. It helps that unlike Tsukasa and Yusuke, he was meant to be seen as annoying, making his ability to mess with them look even better.
    • Due to Villain Decay and the fact that he always blames Decade for everything that goes wrong, even if he’s responsible for it, Narutaki also gets this from the fandom.
  • Most Wonderful Sound: FINAL FORM RIDE
  • Narm Charm: Many fans agree that the finishing move against the Makamou in episode 19 is perhaps the dumbest thing that has ever been on Kamen Rider.......and perhaps the most awesome thing ever as well thanks to a well coordinated attack with The Power of Rock.
  • Nightmare Fuel: Judging by her reaction, Momotaros-possessed Yusuke was this for Natsumi.
    • Some of the deaths in this series, particularly Great Shocker's assault on The Multiverse, where people get killed onscreen.
  • Tastes Like Diabetes: Kivala. She's small, has a cute voice, and has some of the most adorable moments.
  • The Scrappy:
    • Tsukasa Kadoya, for being a jerk who seems to solve everything and having his Magnificent Bastard tendencies repeated over and over again in movies or taking the spotlight away from other Riders, gets this treatment. That being said, most fans sees him unfit for a typical Rider protagonist due to his overall attitude. Though he smartened up later during the events of Zi-O.
    • Even bigger is Yusuke Onodera, Godai's counterpart. Starting out as a selfish asshole aka THE EXACT OPPOSITE OF THE ORIGINAL KUUGA, he only got worse when he barely did anything over the course of the show, not even transforming all that much.
  • "Seinfeld" Is Unfunny: Decade is well-seated with the fans initially but after subsequent crossover movies keep portraying the titular rider leading the villainous army to kill all Riders and/or destroying the world and yet he is always right anyway for the sake of plot twist, the series plummeted to slightly above Wizard in terms of popularity. And considering fans' reception about the latter show...
  • Special Effect Failure: Kivaara initially made her first appearances as a CGI model. A few episodes later and she became a toy on a string.
    • Taken to an absolutely appalling level in episode 12, where Kivaara has CGI in one scene and then instantly shifts back to toy-on-a-string for her next appearance in the very same episode.
  • Tear Jerker: The deaths of Kuuga!Yashiro and AU!Hibiki. Some could probably counted as well.
    • Tsukasa is constantly called the destroyer of worlds. While at first it looks like just brushes it off or don't let it outwardly effect him that much, over the series you can tell that deep down he is hurt by those accusations and despite his friends constantly tried to reassure him by the time of the final episodes he sounded like he simply is resigned himself to that fate, especially when Wataru told him he was supposed to destroy the AU riders not befriend them and his actions were destroying the worlds, and by the Movie War 2010 he had fully embraced that. He might not be the kindest person in the world but he had feelings also.
  • They Wasted a Perfectly Good Plot: The whole "Orphenochs can't go to school" aspect was just mentioned by one or two lines and that is it. Even after Faiz is revealed to be one, it doesn't get mentioned again.
    • More than likely, Faiz's plot wasn't expanded because it was very similar to Kiva's, so rather than focusing on the Fantastic Racism, they just used the arc to introduce Kaitou.
    • Tsukasa being this universe's incarnation of The Great Leader of Dai-Shocker who lost his memories while traveling the worlds. This idea could have easily been the center plot of the series itself and could have been explored how even such an iconic villain in the franchise is capable of redemption, change and goodness, especially since he's the anniversary Rider of Kamen Rider itself. Tsukasa's past and how he even lost his memories are barely even touched upon in the movie.
  • The Un-Twist: It's hard to not see the Tsukasa is leader of Daishocker twist coming when the initial rumors were that Tsukasa was either gonna be an Otaku or an Evil Overlord.
  • What an Idiot!: No, Fourteen, forcing your most loyal servant watch his brother get brainwashed while telling him you've been lying to him the entire time about his education program WILL HAVE NO CONSEQUENCES WHATSOEVER.
    • In the world of Black RX, Apollo Geist claims that Tsukasa is trapped in the parallel world of Black forever. As he is saying this, meanwhile in that other area, Schwarian leaves a portal to the world of Black RX open while fighting Decade.


How well does it match the trope?
