Film / OOO, Den-O, All Riders: Let's Go Kamen Riders

Go To

OOO, Den-O, All Riders: Let's Go Kamen Riders is 40th anniversary movie of the Kamen Rider franchise. Premiered in Japanese theatres on April 1, 2011.

After Ankh accidentally coughs up a Cell Medal in the past while travelling with New Den-O, Shocker uses the technology to create a new Kaijin that manages to defeat the original Double Riders. Due to this, the past is rewritten so that Shocker now rules the world, and all the other Riders cease to exist. It's up to the Kamen Riders OOO, Den-O and New Den-O, accompanied by Ankh, to fix the mess they caused and save all of humanity.


This movie contains examples of the following tropes:

  • Adaptational Badass: The Great Leader's original incarnation didn't put up much of a fight. This one takes all of the Riders to finally put down.
  • Adaptational Heroism: When the the secondary Riders show up for the All Rider Break, some of them are from Ryuki, which means a lot of them aren't the "team up and take on an Evil Overlord" type. We're lookin' at you, Takeshi Asakura (though by no means only at you.)
  • Arc Number: 40. For this 40th anniversary film we go from 2011 to 1971 then back again. Plus the All Rider Break forms the shape of the number 40.
  • Attack of the 50-Foot Whatever: King Dark, naturally. However, even he's dwarfed by the Great Leader's One-Winged Angel form, which destroys King Dark just by showing up.
  • Bad Future: Ankh unwittingly causes a Butterfly Effect when he gets jostled hard enough to cough up a Cell Medal while in the past with New Den-O. This Cell Medal is picked up by a Shocker goon, who then takes it to General Black. As it turns out, they had been experimenting with a reverse-engineered Core Medal. The resulting Greeed ended up defeating the Double Riders, causing a future where Shocker and other such evil organizations control the world.

  • Big Bad: Only the Great Leader of Shocker himself.
  • Big Damn Heroes: During the battle in the present, Kamen Rider V3 arrives, leading the other main Kamen Riders. When the Great Leader transforms, Kamen Rider Birth arrives, leading the Secondary Riders.
  • Canon Welding: When General Shadow runs away, he is stopped by four other heroes. As Owner notes, "Kamen Riders aren't the only allies of justice." These four heroes are Kikaider, Kikaider 01, Inazuman, and Kaiketsu Zubat, all made by Shotaro Ishinomori.
  • Casting Gag: Tomokazu Seki, who fills in for Daisuke Ban as the voice of the tokusatsu incarnation of Kikaider (Jiro), previously voiced the anime incarnation of the character in Android Kikaider: The Animation.
  • Chekhov's Gunman: The man in white who threw the OOO Driver back to Eiji.
  • Chekhov's Gag: At the beginning of the film, OOO fights three Imagin, believing them to be Yummy even though they don't bleed Cell Medals, but Ankh arrives and tells him they're not Yummy at all. Yet Ankh was later able to procure a Core Medal from another Imagin: Momotaros.
  • Chuck Cunningham Syndrome: Both Another Agito and Dark Kiva are absent from the army of extra riders Birth summons. While it's understandable why either King/The Bat fangire or Taiga Noboru wouldn't show up as the latter (former was an outright villain, latter is already present in the army as Saga), it's not known why Otoya Kurenai isn't present, given that he isn't present in the army as Proto-Ixa, and no explanation whatsoever is apparent for why Another Agito is absent.
    • In a more minor example, there is no hint of Ryotaro and Hana, the main human characters of the original Den-O series, despite Kotaro (Ryotaro's grandson) being one of the main characters.
  • Continuity Porn: But of course. The most obscure reference is either Snack Amigo (Chiyoko's has turned into one; it was the hangout in the original series for about five episodes or so.) or Mitsuru and Naoki (names not chosen by accident; they're two kids who became Those Two Guys in the last arc of the original series; apparently they were from the future all along?) Also, Nokko is named for three girls with -okko names. And of course, every monster was a Monster of the Week from a past series, some every bit as old as Snack Amigo.
  • Continuity Snarl: Somewhat unsurprising, given Yasuko Kobayashi wasn't writing this one.
    • In the film, Eiji has full sets of all medalsnote  except for Purple and Orangenote ; Ankh's presence means that this can't take place after the series (when Eiji would have full sets of all medals), and assuming the movie is supposed to take place after episode 29 (as implied by the episodes), Eiji would have full sets of Red and Blue medals, but only 1 of all the other colors introduced in the series by that pointnote .
    • The film states it's set in 1971, but most of the elements shown in the past (the Kamen Rider Squad, the designs of the Double Riders outfits, the outfits of the Shocker grunts, Ikadevil and Ambassador Hell are shown as resurrected despite the fact that they didn't originally die until 1972) are more consistent with elements from 1972.
    • Kame Bazooka is present despite the fact that Destron wasn't created until 1973, after the defeat of Gel-Shocker. One could write that off as Shocker simply creating the monster earlier in this timeline...if it wasn't for the fact that it still has the Destron symbol on its belt.
    • Eiji is able to ride his bike in the altered timeline despite the fact that there would obviously not be any Ride Vendors for him to use.
  • Demoted to Extra: Being a Kamen Rider crossover movie, this applies to most returning heroes and villains beyond the stars. A notable example is Decade, the recent anniversary Rider, whose appearance here has him as Fake Shemp in a quick cameo like many of the past Riders.
  • Demoted to Dragon: All of the series' past main villains that appear here are reduced to the Great Leader's flunkies.
  • Disney Death: In short order, Teddie, Naomi, Owner, Urataros, Ryutaros and Kintaros. Who all die during the escape from the failed attempt at preventing the creation of the Shocker Greeed and only come back in the Climax once the Riders' history is restored.
  • The Dragon: General Black to the Great Leader of Shocker.
  • 11th-Hour Ranger: Kamen Rider Birth and dozens of other extra riders suddenly arrive to back up the primary riders when the Great Leader becomes Rock Great Leader.
  • 11th-Hour Superpower: Ankh ends up being able snatch away the Core Medal that started the trouble, as well as yank a Medal from Momotaros, giving them to Eiji to become Kamen Rider OOO TaMaShii Combo.
  • Evil Versus Oblivion: One way to look at many of the villainous Riders who teamed up to defeat the Great Leader. While some of them are nasties, the Great Leader is currently going Omnicidal Maniac and destroying his own minions along with the heroes...
  • The Faceless: All Fake Shemp Riders and villains of course. A notable example are Riders 1, 2 and V3, who do not appear out of their Rider forms despite being voiced by their original actors (Hiroshi Fujioka, Takeshi Sasaki and Hiroshi Miyauchi).
  • Fake Shemp: Inevitable, given the number of past heroes and villains going back to 1971. Aside from the main stars, almost all of the Kamen Riders appear in-costume only and voiced by replacement voice actors. It also affects many of the villains, along with the other four "allies of justice", though Hiroshi Miyauchi returns to voice Zubat as well as V3, and Tomokazu Seki, who previously voiced Kikaider in Android Kikaider: The Animation, voices the tokusatsu incarnation of the character here. Really, it's surprising that so many were the original actors.
  • For Want of a Nail: The whole reason that the Bad Future exists is because Ankh's greed in trying to get the Core Medals during 1971 when all of the other Greeed were dormant caused him to leave the Den-Liner in a hurry, causing Eiji to go after him and get into a scuffle. One of his Cell Medals dropped out during the scuffle getting picked up by a Shocker Mook who then presented it to his leaders, and thus escalated to the main plot of the movie.
  • Freeze-Frame Bonus: during the All-Rider Break, it can be picked out that not every Rider is riding a motorcycle. Agito's Tornador is on its Hover Board form, what looks like Double's RevolGarry bringing up the rear, among others.
  • Gas Mask Mooks: The Shocker Greeed. The gas mask is probably inspired by the look of the Shocker Soldiers in Kamen Rider: The First and Kamen Rider: The Next.
  • Heroic Sacrifice: Teddie stays in 1971 to save Naoki and the Kamen Rider Scouts from the Shocker monsters, dying in the process.
    • An unusual example with Naoki, who stays in 1971 to prevent the Double Riders from being fully brainwashed through The Slow Path by becoming a Shocker Scientist and later declines to be taken back to his era.
  • I Choose to Stay: A variation with Naoki, his grown-up self declines Kotaro's attempt to take his child self back to the present as not only did he prevent the Double Rider's brainwashing, but he had a fulfilling and happy life despite all the losses he had, which includes being the father of his best friend, Mitsuru.
  • In Spite of a Nail: Despite the fact that Shocker now conquered the world in 1971, all future evil organizations and monster races still emerged, only now they have been incorporated into Shocker.
  • The Last of These Is Not Like the Others: the first promotional trailer features the DenLiner going past images of the headlining Riders in reverse chronological order (from OOO to Ichigo), that ends with the Shocker mooks.
  • Legion of Doom: Not Dai-Shocker, or Super Shocker. Instead its the original Shocker, only this time its ambitions to take over the world have been more fruitful thanks to the Shocker Greeed. By 2011, their ranks consist of villains and monsters from across Kamen Rider history. Thankfully, the respective riders they fought against appear to take them on once more.
  • Mascot Mook: The Shocker Soldiers become this in the advertising and net movies, to the point where it's downright weird to see them trying to kill people in the actual film.
  • Mythology Gag
    • Naoki and Mitsuru are named after boy Rider Scouts from the original series, while Shigeru is named after Shigeru Tama, the main Rider Scout from V3. This gag would be repeated in Super Hero Taisen GP.
    • Rock Great Leader is a beefed-up version of the Great Leader's Delza Army incarnation from the finale of Kamen Rider Stronger.
  • Omnicidal Maniac: Rock Great Leader ends up destroying every member of Shocker that the heroes hadn't already killed.
  • One-Winged Angel: The Great Leader transforms into the Rock Great Leadernote  after OOO defeats his normal form.
  • Plot Hole: A lot of plot elements are either pulled out of or disappear into nowhere, to the point where thinking about them too hard will probably make your head throb. Most jarringly is that at no point in the movie is the timeline actually fixed as the heroes desperately wanted. Shocker is defeated in the present by the Riders (Most of whom shouldn't exist in this timeline anyway), but when the credits role, the bad timeline is still the one which exists.
  • The Slow Path: Naoki gets left behind in the past after the failed attempt by the Den-Liner Crew to stop the creation of the Shocker Greeed. He would grow up to become the Shocker scientist who removed the Double Riders' brainwashing, and, shockingly, his best friend's, Mitsuru, father.
  • Super Mode: OOO's one-time Tamashii Combo allows him to defeat the Great Leader, who before then overpowered 25+ Kamen Riders.
  • Temporal Paradox: Naoki and Mitsuru are best friends in the contemporary era, but when Naoki gets left behind in 1971, he grows up to become Mitsuru's father, which wouldn't have been possible if they weren't friends in the first place.
  • Timey-Wimey Ball: A change in history allowing Shocker to conquer the world in 1971 results in all Riders after the original two being apparently erased from existence, with the exception of those aboard the Den Liner. However, they all spontaneously reappear to fight Shocker in 2011. Owner's explanation is that they are here because they were not erased from the memories of the people.
  • A Twinkle in the Sky: OOO does this to the Great Leader.
  • Villain Decay: Somewhat inverted for the Shocker Combatmen. While they're still mooks to be mowed down en masse by our heroes, they're far more sinister than before, to the point that they outright kill people during the movie.
  • The Worf Effect: The Shocker Greed is shown to be powerful enough to defeat the Double Riders easily.
    • Gets on the receiving end later when they have their rematch in the present. With him going down in 2 hits.
    • General Black gets easily killed by OOO in the present.
    • The Great Leader kills King Dark, Darom, Apollo Geist and General Jark just by appearing and causing them to fall into a crack on the ground.
  • You Are Not Alone: All of the previous main Kamen Riders arrive to assist New Den-O, OOO and the Double Riders when they find themselves overwhelmed by Shocker's troops.
