"A generation ends. A new era begins."

“For all who love the Kamen Riders…”
Second Tagline

Kamen Rider Heisei Generations FOREVER is the third and final installment of the Heisei Generations Series movies and the tenth film in the Kamen Rider franchise’s annual “Movie War” crossovers. Apart from featuring Kamen Rider Zi-O and Kamen Rider Build, this movie also serves as a shared tribute episode to Kamen Rider Kuuga, Kamen Rider Den-O, and Kamen Rider W.

Kamen Riders are hope bringers, as they protect people from the evil forces from time to time. But… they are only fictional heroes of a television series.

Are the Kamen Riders nothing but fictional characters?

A powerful Time Jacker named Tid appears, declaring that the story of Heisei Kamen Riders, starting from Kuuga, will end now. In order to accomplish this, Tid creates Another Den-O and Another Double, ordering them to pursue a young boy named Shingo. While Sougo Tokiwa attempts to protect the boy, he meets a Kamen Rider fan named Ataru, who demoralizes the existence of the Kamen Riders. On the other side, Sento Kiryu attempts to take on Tid alone, but he’s defeated and seemingly brainwashed to fight for Tid’s cause. As the mystery uncovered, the heroes head to the Kurogatake Mountains, wherein lies the tomb of Riku: the very first Kuuga and the protector of Linto tribe, as well as as the key place for the existence of Heisei Kamen Riders.


This movie has examples of the following tropes

  • All Just a Dream: Two examples:
    • After Ataru witnesses Shingo being taken away by Another W and Another Den-O after Grease was defeated, he tells Sougo and Sento not to worry about it since it's all just a dream. It's not a dream and only gets worse as Tid starts spreading monsters and Futaros' powers weaken.
    • Sougo wakes up in 9-to-5 Do halfway through the film, with Woz standing over him. Then Sento walks in to say hi, that their experiences were real, and Sougo pulls the Double Ridewatch out of his pocket.
  • Amnesiac Dissonance: Everyone who has their personalities altered to fit into the real world end up with an opposite personality to their own.
  • Big Damn Heroes: Three examples:
    • When it seemed impossible for our protagonists to return to 2018, the Den Liner appears to help ferry them back to 2018, right into Tid’s base.
    • Advertisement:
    • Then, when Tid had Sougo, Geiz, and Futaros held down in time and were going to kill them, Ryotaro Nogami, the original Den-O and the Taros intervene to save our protagonists and personally deal with Another Den-O.
    • After Den-O personally deals with Another Den-O, the people under attack in the real world start calling out to the Kamen Riders, causing the Heisei Riders to manifest in the real world to protect them.
  • Book-Ends: The first scene begins with an amnesiac Sougo telling his friends he aced a test. The last scene begins with normal Sougo telling them he didn’t even take it.
  • Call-Back:
    • Sougo jogs Banjo’s memories of him by referring to himself as “that stupid futurer”, referring to their meeting in Zi-O’s first episode.
    • Sento uses his experiences as a result of Evolt’s experiments to get over the idea that he’s just nothing but a manufactured hero.
  • Chekhov's Gun: The Double Ridewatch, which initially seems to be the usual “use this Ridewatch to defeat the Another Rider” McGuffin, turns out to be useful in transporting Zi-O, Woz, and Sento back to Ataru’s world.
  • Co-Dragons: Another Den-O And Another Double are this to Tid.
  • Early-Bird Cameo: Agito, Ryuki, the Taros, Decade, and Ghost make voiced appearances here, chronologically before appearing in the series proper.
  • Early Installment Weirdness: Decade is still shown with the original Decadriver as opposed to the upgraded version he has in Zi-O proper. Justified, as he is merely a manifestation of Decade based on memories of the crowd, and the movie takes place right before the Ghost/Decade tribute episodes where the Neo Decadriver debuts.
  • Fake Shemp: Most of the returning Riders (and Mr. Belt) are voiced using stock audio. Kuuga is the exception, not making any sounds not generated by the Arcle.
  • Finishing Move: Tid gets a Rider Kick from all twenty main Heisei Riders near the end. Every last one. Ouch.
  • Foreshadowing: The movie hints at a lot for Zi-O’s end game.
    • When Tsukuyomi loses her memory she doesn’t react to the name Tsukuyomi. Turns out that’s not her real name.
    • Tid becomes Another Kuuga just like how Swartz becomes Another Decade. Similarly Tid is able to become Another Ultimate Kuuga when Hiryu is later able to become Another Zi-O II.
    • The end of the movie has the various Neo-Heisei henchmen attack the city, the end of Zi-O has the same thing as the various Rider histories are fusing with Sougo’s world but with all Heisei henchmen and monsters.
    • Tid wants to erase the Kamen Riders and rule the world which is a fourth wall-breaking version of Swartz’s goal.
  • The Fourth Wall Will Not Protect You: Tid’s plan goes further than stealing Kuuga’s history from the timeline, but erasing the history of the franchise’s televised run in the Heisei era that began with the Kamen Rider Kuuga show.
  • Good All Along: Futaros’s actions in the movie were to protect Shingo.
  • Make Wrong What Once Went Right: Tid’s plan to end the Heisei Riders involves removing Shingo from the timeline because of his status as a Singularity Point, allowing Tid then as Another Kuuga to Ret Gone all of the Heisei Riders at once.
  • Mangled Catchphrase: Sougo, as per usual.
    ”Now, tell me your sins.”
  • Mooks: Tid calls upon every henchmen from the last 10 years to begin his conquest.
  • Mythology Gag:
  • Never the Selves Shall Meet: Averted, as Another Den-O interacts with Ataru face to face.
  • Non-Serial Movie: Played with. According to the producer, the characters not recognizing the Den-Liner during the proper Den-O tribute episode in Zi-O is because this movie is non-canon. However, a Broad Strokes version of the movie’s events is assumed to have happened in the series regardless, as there is no other depiction of the acquisitions of the Double and Kuuga Ridewatches, and the calendar date indicates that the movie would have occurred between episodes 12 (the second part of the Gaim tribute) and 13 (the first part of the Ghost/Decade tribute).
  • Ripple Effect-Proof Memory: Singularity Points from Den-O’s lore are a plot point. The reason Tid kidnaps Shingo from the past is because his memories of growing up watching Kamen Rider on TV are what stabilizes the franchise from his attempts to erase it, and Another Den-O is defeated without needing the creation of a Den-O Ridewatch because Ryōtarō’s status as a Singularity Point makes him immune from being erased by changes in the timeline, allowing him to keep his powers even when the Another Rider would have stolen his history.
  • Stable Time Loop: The events of the movie are caused by a chain of events that depend on Shingo being captured and Ataru later becoming Another Den-O.
  • Whole Plot Reference: As Producer Shinichiro Shirakura puts out:
    The setting of Heisei Generations FOREVER is of this real world. I think its way of dealing with the relation between the movie and the TV show is not similar to the previous Rider movies, but to one Ultraman movie named "Tiga, Dyna and Gaia: the Decisive Battle in Hyperspace".

How well does it match the trope?
