History Fanfic / KamenRiderXOver

* PsychicPowers: In this world, humans who wield psychic powers called "espers".

* AdaptationalEarlyAppearance: Kamen Rider 3 and 4 in canon wouldn't show until ''Series/KamenRiderDrive''.

The ''Kamen Rider X-Overs'' are a fanfic series written by [[https://archiveofourown.org/users/mtnetsurfer/pseuds/mtnetsurfer mtnetsurfer]] that crosses over various incarnations of ''Franchise/KamenRider'' with other media, typically anime. So far five stories have been completed, with more on the way.

* HeroOfAnotherStory: ''Skyrider Wonderland'' reveals that in addition to the Kamen Riders, Neo Shocker had been opposed across the world by heroes like the [[Manga/JojosBizarreAdventureStardust Crusaders Stardust Crusaders]], the [[Series/{{Beetleborgs}} Big Bad Beetleborgs]], the VideoGame/IkariWarriors military group, the [[Series/TheMysticKnightsOfTirNaNog Mystic Knights]], and a pair of psychic children calling themselves the [[VideoGame/PsychoSoldier Psycho Soldiers]].
* InSpiteOfANail: Despite their enemy being Neo Shocker this time around, the [[Manga/JojosBizarreAdventureStardust Crusaders Stardust Crusaders]] still traveled to Egypt, led by Joseph Joestar and his grandson, Jotaro Kujo.

* PsychicPowers: In this world, psychic powers are common among humans, called "espers". While Itsuki Kawasumi/Kamen Rider 4 is one of the most prominent espers, others psychic heroes include the [[Manga/JojosBizarreAdventureStardustCrusaders Stardust Crusaders]] and the [[VideoGame/PsychoSoldier Psycho Soldiers]].

-->'''Rider Corps:''' "Even if there's no God or Buddha, there will always be the Kamen Riders!"

*** ''Cyborg Stronger'' has Emperor, one of the Blessed who desires to see the end of the Kamen Riders after they foiled his own evil schemes and forms an alliance with General Shadow since Stronger was the only one he could find so far. After the Delza Army is destroyed, his fate is unknown but he is wanted by the United Nations who request the 00 Riders' aid in tracking him down.

* RecursiveCanon: As the Kamen Riders start to become more well-know, the actual Toei studios starts making TV shows about them.

*** ''Super-1 Bebop'' has Vicious, TheQuisling and a Social Darwinist from the research center that created Super-1. He believes that the Dogma Kingdom is meant to mold the world in their image. Naturally he despises Super-1 for opposing them, but he never really acts against the heroes since he's no match for a Kamen Rider.

** Kamen Rider G becomes part of the main Rider Corps, and ZX appears slightly earlier than canon.

* CanonImmigrant: Kamen Riders Omega, Alpha, and Sigma are shipped over from ''Series/KamenRiderAmazons''.

* YourNormalIsOurTaboo: Discuss in regards to the Dogma Kingdom. They proudly practice eugenics and see nothing wrong with it, while on Earth such practice is either frowned upon or outright ''banned'', especially after the events of World War II. By contrast, Dogma considers it utterly foolish to have relationships based on emotional connections, only seeing value in what descendants a relationship can bring, compared to Earth society where pairing up based on emotional compatability is considered natural. The Bebop Riders note that Dogma isn't evil for thinking eugenics is the right way to live, rather they're evil for forcing ''other'' races to live the way they do.

* DiesDifferentlyInAdaptation: Occasionally a MonsterOfTheWeek will be destroyed by Rider or finishing move that's different from canon.

*** ''Super-1 Bebop'' has Vicious, TheQuisling and a Social Darwinist from the research center that created Super-1. He believes that the Dogma Kingdom is meant to mold the world in their image. Naturally he despises Super-1 for opposing them, but he never really acts against the heroes since he's no match for a Kamen Rider.

** Heart, Bang, and ZX all use the Helldiver, a modified Suzuki DR250S.

** ''Rising of the Kamen Riders'' adds Kamen Riders 3 and 4 to the mix, with Motoyasu taking over as Kamen Rider 3 around the the midpoint of the story while Naofumi/Kamen Rider 1 and Ren/Kamen Rider 2 go to fight Shocker worldwide. He's later joined by Itsuki as Kamen Rider 4, and later all four fight together not long before Shocker becomes Gel-Shocker.

* {{Doorstopper}}: ''Rising of the Kamen Riders'', which makes sense since it adapts the original ''Series/KamenRider'', which had 98 episodes and two original movies, making for 100 chapters total. The only individual story of mtnetsurfer's that's longer is ''Fanfic/MyHeroSCP''.

* OncePerEpisode: Each story always ends with the lead Rider calling out, "Rider Banzai!" Expanding on the literal translation of this, the final line in each story is always, "Long live the Kamen Riders!"

*** Super-1 has Vicious, TheQuisling and a Social Darwinist from the research center that created Super-1 and believes that the Dogma Kingdom is meant to mold the world in their image. Naturally he despises Super-1 for opposing them, but he never really acts since he's no match for a Kamen Rider.

** X Beats has Kamen Riders Angel, Life, SSS, and Eyez.
** Cyborg Stronger has Stream and Arsenal.
** Skyrider Wonderland has Guard, Blood, and Ground.
