Big Bad / Kamen Rider

Go To

The many Big Bads of Kamen Rider. In addition to television series, expect each of the associated movies (particularly the Summer Movies and Movie War crossovers) to have their own Big Bad as well.



Showa Era

  • Kamen Rider and Kamen Rider V3 both have the Great Leader, who was responsible for founding the evil organizations Shocker, Gel-Shocker and Destron, all in succession.
  • Kamen Rider X introduces the series' first non-Great Leader Big Bad in the General Commander of GOD, a mysterious individual at the head of the Government of Darkness who used numerous objects as mouthpieces with no clue to his true form. Halfway through he stops sending messages and the true leader of GOD turns out to be the colossal King Dark (who is really a robot piloted by Doctor Noroi), with the implication that the GOD General Commander was either a flunky or alias used by him.
  • Kamen Rider Amazon has the Ten-Faced Demon Gorgos, the leader of the evil Geddon. Halfway through, Geddon gets defeated and is replaced by the Garanda Empire led by Great Emperor Zero. Zero himself answers to the mysterious cloaked Ruler, who claims in the final episode to have been The Man Behind the Man to Geddon as well.

  • Kamen Rider Stronger sees the return of the Great Leader in a new form as the leader of the Black Satan organization. Following Black Satan's downfall two-thirds of the way through, the traitorous General Shadow seizes on the vacuum left by Black Satan to form his own Delza Army. Towards the end of the show however, the Great Leader returns and not only hijacks the Delza Army, but reveals himself to be behind both GOD and Geddon as well (no mention of the Garanda Empire though).
  • Kamen Rider: Skyrider has the master of Neo-Shocker, who is yet another form of the Great Leader.
  • Kamen Rider Super-1 has the Dogma Kingdom led by Emperor Terror Macro. Once they fall, their place is taken by Jin Dogma, the organization behind that organization, which is led by Marshal Demon.
  • Birth of the Tenth! Gather All Kamen Riders!!, has the Badan Empire led by Ambassador Darkness, the Backup Twin of Ambassador Hell from the original Kamen Rider series. At the end of the film it's revealed Darkness was working for the Generalissimo of Badan, who (surprise, surprise) is really another incarnation of the Great Leader.

  • Kamen Rider BLACK had the Creation King.
  • Kamen Rider BLACK RX had General Jark of the Crisis Empire, who ultimately turned out to be subordinate to Grand Lord Crisis, who... may be Great Leader, it's not entirely clear, but they have the same voice actor in Gorō Naya, whose distinctive voice was Great Leader's calling card.
  • Shin Kamen Rider: Prologue had the Syndicate as well as the CIA.
  • Kamen Rider ZO had the Neo Organism.
  • Kamen Rider J had the Fog Mother.

Heisei Era (Phase 1)

  • Kamen Rider Kuuga, the first of the Heisei Riders, had N-Daguva-Zeba, the Gurongi Lord.
  • Kamen Rider Agito had the Overlord of Darkness.
  • Kamen Rider Ryuki had Shiro Kanzaki, one of the few Non-action Big Bads of the Heisei era.
  • Kamen Rider 555 had the Smart Brain heads (one of whom is voiced by Goro Naya) and later the Orphnoch King.
  • Kamen Rider Blade had Hiroshi Tennoji, though at the end of the series he was usurped by Kanai/Giraffa Undead, the last member of the Royal Clubs, who was ticked at being used by Tennoji. Ultimately however, the real Big Bad may just have been the Sealing Stone, since it was what created the Undead in the first place.
  • Kamen Rider Hibiki had The Man and The Woman and all their myriad clones. We don't even meet the actual originals until the finale. And its even possible that they aren't the originals after all...
  • Kamen Rider Kabuto had Masato Mishima and eventually his collaborator Negishi.
  • Kamen Rider Den-O had Kai the Singularity Point and master of the Imagin.
    • Kamen Rider Den-O: I'm Born has Thief King Gaoh, who hijacks the Den-Liner so he can retrieve his own train, the Gaoh Liner.
  • Kamen Rider Kiva had King/Bat Fangire.
  • Kamen Rider Decade is complicated, taking place over a Multiverse of alternate realities to past Rider series, each with their own Big Bad. It eventually introduces Dai-Shocker, a Legion of Doom comprising villains and monsters from across Kamen Rider history, which goes through several leaders.
    • The World of Kuuga has N-Gamio-Zeda, the equivalent to N-Daguva-Zeba.
    • The World of Kiva has the Beetle Fangire, the equivalent to the Bat Fangire. He is eventually followed by Yuki, the Fangire Queen who is wed to Apollo Geist.
    • The World of Ryuki has Kamata (Kamen Rider Abyss), who turns out to also be the Paradoxa Undead, who was brought by Narutaki to this world from...
    • The World of Blade has Hajime Shijo, who transforms into both Kamen Rider Chalice and the Joker Undead. As it turns out, Kamata was The Dragon.
    • The World of 555 has Momose, the Tiger Orphnoch, the leader of the Lucky Clover at Smart Brain High School.
    • The World of Agito, with nary a mention of the Overlord, has the Buffalo Lord Taurus Ballista, the equivalent to the El Lords, who were the Co-Dragons to the Overlord.
    • The World of Den-O has the Alligator Imagin, who enacts his own scheme to change the past. Also appearing is Shilubara (Mimihiokko) as a Greater-Scope Villain, leading to the Den-O & Decade film in which he features alongside his brother Goludora (Kuchihiko), who stands as the Big Bad after Shilubara is slain.
    • The World of Kabuto has Soh Otogiri, the Phylloxera Worm,
    • The World of Hibiki, with nary a mention of the Man and the Woman, has Gyuki, actually a fallen Hibiki.
    • The World of Negatives, the Mirror Universe, has Otoya Kurenai (Kamen Rider Dark Kiva), leader of the Dark Riders and Alternate Self of the heroic, deceased Otoya Kurenai from Kiva. Uniquely, this Otoya survives his run on Decade.
    • The World of Diend, based on the filmKamen Rider Blade: Missing Ace, has Fourteen.
    • Special mention goes to the World of Shinkenger, the world in which Samurai Sentai Shinkenger takes place, where the heroic Shinkengers fight the monstrous Ayakashi, which is incorporated into Decade when the Hikari Studio crew visit for a crossover. The Big Bad for this arc turns out to be Chinomanako who steals the power of Kamen Rider Diend; as Shinkengers' is a world without Riders, Chinomanako's presence becomes a threat which requires the combined strength of Decade, Kuuga and the Shinkengers to put down. Dokoku Chimatsuri, leader of the Ayakashi and Big Bad of Shinkenger, does not appear but can be counted as a Greater-Scope Villain.
    • The World of Black RX has the Crisis Empire represented by Schwarian, whilst Emperor Crisis is mentioned as a Greater-Scope Villain. It is in this world that Dai-Shocker, represented by Apollo Geist, makes their first appearance, recruiting the Crisis Empire into their alliance. It is also established that Dai-Shocker previously recruited Gorgom, from the World of Black.
    • Apollo Geist himself, whose original incarnation was The Dragon to King Dark, hails from the World of X-Rider, with a new incarnation of King Dark appearing in All Riders vs. Dai-Shocker.
    • The World of Amazon has the Ten-Faced Demon Llumu Qhimil. Equivalent to Gorgos from Amazon, Llumu Qhimil the leader of Geddon, which is now a part of Dai-Shocker.
    • The film All Riders vs. Dai-Shocker reveals that the Great Leader of Dai-Shocker was in fact none other than protagonist Tsukasa Kadoya (Decade) himself, before losing his memory and wandering the multiverse. Returning to the World of Decade, Tsukasa regains his memory and becomes Great Leader once again, revealed as the mastermind behind Dai-Shocker's plan to destroy all Kamen Riders and invade all the A.R. Worlds only to be usurped by Nobuhiko Tsukikage, an incarnation of Shadow Moon who is ultimately vanquished when Tsukasa joins with the previous Kamen Riders to dake down Dai-Shocker.
    • In the World of the Rider War, a combination of the nine Heisei Rider worlds, Apollo Geist takes control of the remaining monsters, marrying the Fangire Queen and thus becoming the half-Fangire Super Apollo Geist.

Heisei Era (Phase 2)

Reiwa Era

Crossover Films

Super Hero Taisen


  • Kamen Rider SD, a comedic Continuity Reboot minifranchise, has the Great Leader back, now as the master of Gran Shocker, an alliance of villains up to Black RX.
  • Kamen Rider: The First, a Continuity Reboot film, has Shocker led by the Elderly Gentleman, actually Doctor Shinigami, a Dragon from the original series. The sequel Kamen Rider: The Next, which adds V3 to the mix while keeping the bad guys as Shocker, brings back the Great Leader.
  • The Affectionate Parody Kamen Rider G has Daido Oda (Phylloxera Worm), field leader of the terrorist organization Shade working to get their true leader Seizan Tokugawa busted out of prison.
  • The Alternate Continuity Kamen Rider Amazons has a Big Bad Ensemble: the scattered Amazons are the main threat and largely operate on their own, though some of the more powerful Amazons (like the Bat or Ant Queen) are able to command weaker members of their kind. On the other side, the Nozama Pharmacy (specifically their chairman, Takaaki Tenjo) are responsible for creating them in the first place and are willing to let people die brutal, gory deaths and keep the four thousand maneating monsters roaming the countryside secret just to keep the Amazon Cells to themselves. To top it all off, Tenjo released the Amazons in the first place to cause this whole mess. Season 2 is a bit more complicated as Mamoru and his group started the new outbreak, Jin is constantly hunting down Chihiro with intent to kill him, and Nanaha (now an Amazon) is rampaging about and becomes Jin's Final Boss. Though Tenjo could still be considered the overall Big Bad, seeing as every single thing that happens in both seasons was because of him releasing the Amazons in the first place. The Grand Finale movie Kamen Rider Amazons The Last Judgement' has Einosuke Mido/Kamen Rider Amazon Neo Alpha.

Web Miniseries

  • Carrying on from where Super Hero Taisen GP left off, Kamen Rider 4 has the Great Leader, once again trying to use Time Travel to restore Shocker.
  • Kamen Sentai Gorider has Kuroto Dan, who masterminded the events of the miniseries as a means to revive himself and was incognito as Kazuma Kenzaki all along.
