YMMV: Kamen Rider Decade

  • Awesome Music: Episode 19.
  • 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 stronger. 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.
  • Character Shilling: The original Kabuto (Souji Tendou) is all but directly called the strongest Kamen Rider ever, and he effortlessly beats down Decade and Diend at the same time.
  • 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.
  • Game Breaker: Decade and Diend's Complete Forms.
  • 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, only Shuichi Kitaoka/Zolda was a lawyer. In AU!Ryuki, they're all lawyers. Suddenly Zolda's disproportionately large arsenal makes more sense.
  • 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 Mutation: "Mo' fear! Mo' pain! No henshin, Kamen Rider Kuuga!"note 
  • Most Wonderful Sound: FINAL FORM RIDE
  • Nightmare Fuel: Judging by her reaction, Momotaros-possessed Yuusuke was this for Natsumi.
    • Some of the deaths in this series, particularly Great Shocker's assault on The Multiverse, where people get killed onscreen.
  • Out-of-Character Moment: In the novel, Kuuga is the original (Yusuke Godai), but he acts like a more airheaded version of Yusuke Onodera who can't even remember Decade's name (at one point he thinks it's Dickens). In the Den-O world, Momotaros is polite and refers to the other Taros by their actual names rather than his usual nicknames; Urataros is described as "the blue Ryutaros".
  • 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/Off-the-Shelf FX: 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.
  • 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.
  • The Scrappy: Tsukasa, for being a Jerk Stu 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.
    • 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.
  • The Untwist: 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.
