Kamen Rider/WMG

Kamen Rider Faiz 's Smart Brain is an offshoot of Shocker, and the series is set in the Showa Rider's world, albeit a dystopian one.

In the movie Paradise Lost, one of the three Wirepullers of Smart Brain is the Great Leader. After the events of RX, the Great Leader survived and Shocker went into hiding until they formed Smart Brain to try to reestablish their grip on the world.
Further evidenced in the Kamen Rider Eve/Masked Rider Gaia novel. The titular character's bike bears the symbols of both Smart Brain and Shocker, along with the name of Smart Brain's president, Murakami.

Kuuga and Agito take place in a world where the public's memory of Shocker and the Kamen Riders has been wiped away by the Grongi, who the Great Leader is one of.

The past Riders are now reduced to ordinary people with no knowledge of their past rider status.

Takeshi Hongo becomes a university professor later turned security guard years later. Kotaro Minami became a helicopter pilot. Kazuya Oki became an astronaut. Ichimonji Hayato, a photographer. Kazami Shiro, a teacher like Hongo. Jo Shigeru, a pro football player. Murasama Ryou, a pilot.

If there's a Distaff Counterpart version of Kamen Rider, the motif will be butterflies and moths and they would use a glider

It'd be Kamen Glider.

Arghhhh.

Kamen Rider Decade will be the third Rider series to receive an American adaptation.

Nickelodeon currently airs Power Rangers Samurai, which is based off Samurai Sentai Shinkenger. One of the more notable episodes was when the Shinkengers team up with Decade, which Saban is trying to get rights for the episode's footage from Toei. Should they be given the go ahead, the Power Rangers would be teaming up with Decade, so Kamen Rider Decade could be well on its way to becoming a new series for Nick. Perhaps Third Time's the Charm...

Dex would talk about Ferbus being lost in another dimension, and instead of Dex from another world, Dex's biological father would turn into the Black Rider.
Apparently, Saban just registered the trademark for the name Power Rider. We'll see where this goes.

the "power rider" trademark by saban will either be faiz, kabuto, 000, or fourze.

and here's why:

faiz and kabuto: Steve Wang, director of dragon knight expressed interest in bringing them over.

fourze: an attempt to make the us and japanese dubs correct

OOO: most recent, great toyline potential, and I WANT IT.

Agito has two more forms

Named Rising and God.

Guyver is an alternate universe version of Faiz

Quick: A young guy uninvolved with a hidden conflict accidentally gets hold of a set of advanced war gear and has to fight a massive evil organization which employs people who can turn into monsters. Said organization later overtly controls the world. Is this Guyver or Kamen Rider Faiz?

Fangires are The Jade Court.

All thats known about the Jade Court is that they are a vampires native to Asia and we have yet to see a non-asian Fangire. Normal logic would indicate that they are hopping vampires but this is WMG.

The Rider following Fourze will be called Kamen Rider Go.

It will fit the numerological motif. And just think of how many puns they could make.

Or he can be called Go Rider, and he'll have lightning based powers

Decade will reappear in the 2019 series.

He will help out the main Rider when he's in a tough spot, à la the summer movie cameos. He will have ten new sets of cards for Double, OOO, Fourze, and the 2012-2018 Riders.

The majority of Kamen Riders are actually hosts to Spirits of Vengeance.

It was revealed in Ghost Rider comics that the titular characters are not the only hosts to Spirits of Vengeance which are really heavenly beings that latch onto men and women around the world when they most desire Vengeance or Justice and grant them powers but to hide their status as divine intervention they usually pretend to come from other origins and take different intimidating meme forms based on societal arctypes. Many Kamen Riders are in fact hosts to these spirits.

Kamen Rider: Spirits of Vengence came to both Hongo and Ichimonji when they were being converted into cyborgs by Shocker. It was these spirits that allowed them to overcome their brainwashing and become Kamen Riders. Their hellfire powers manifest in their Rider Kicks and Punches that make monsters explode. They along with many other Japanese Spirits of Vengeance took the meme forms of scary dehumanized cyborgs with insectoid motifs.
Kamen Rider V 3: A Spirit of Vengence came to Shiro when his family was killed but it did not manifest it's powers until it allowed him to be injured and turned into a cyborg by the previous Kamen Riders. His large array of unknown powers not shared with his predecessors are extensions of hellfire. Riderman was not a host to a Spirit of Vengeance.
Kamen Rider X: Jin was taken in by a Spirit of Vengeance when his Father and him were almost killed by G.O.D. Due to his fighting underwater his hellfire was instead internalized into the Ridol weapons.
Kamen Rider Amazon: Amazon bonded with a Spirit of Vengeance when the Ten Faced Demon killed his village. Due to being isolated from the rest of the world his sense of morality wasn't quite in line with normal society and as such the Hellfire was potentially fatal to him, instead it was focused into purely enhancing his physical prowess. Unlike most other Showa Riders he took on the meme form of a legendary beast from his home in the jungle.
Kamen Rider Stronger: With the legacy of the Kamen Riders already in place the insect hero of justice meme was well established by the time Joh Shigeru lost his friend to Black Satan. His hellfire was converted into electrical energy.
Kamen Rider Skyrider: Professor Shido called the spirit of Vengeance into Tsukuba when he was forced to turn him into a cyborg against his will. Since the Spirit didn't choose to bond with him itself his powers are more limited and lack an elemental or weapon based attacks.
Kamen Rider Super-1: After Dogma kills the other NASA scientists and astronauts Kazuya's experimental cybernetic space suit is combined with a Spirit of Vengeance which allow him to transform in and out of his Rider form (Did you really believe 'Chi' let him control his cybernetics?), the hellfire manifested in the hand modules.
Kamen Rider ZX: After the Badan Empire killed his sister a Spirit of Vengeance game to him. It's hellfire manifested in the absurdly powerful shuriken he weilds.
Kamen Rider Black and Kamen Rider Black RX: The Kingstone was another fragment of the meteor from which the Bloodgem was taken from but neither Black Sun nor Shadow Moon were Spirits of Vengeance. Not until the Crisis Empire 'killed' Kotaro Minami at which point a Spirit of Vengeance came to him in the guise of solar radiation. Partially due to the unholy energies of the Kingstone hellfire could not be channelled directly through the new Black RX body and had to be focused through form changes into weapons, a trait that future Kamen Rider Spirits would use.
Kamen Rider Hibiki: All Oni are undeniably wielding powers of Spirits of Vengeance. We even see one get killed by Danny Ketch in the pages of Ghost Rider itself.
Kamen Rider Den-O: The Taros, Teddy and Deneb are not really Imagin as they claim. Owner is in on this but no one ever tells the Riders.
Kamen Rider Double: Museum bound memories of Spirits of Vengeance in all of the Rider Drivers to protect the users from the dangerous side effects of Gaia Memory use and to focus the memory into Rider armor instead of a dopant body.

Power Rider will be an adaptation of W

And Sokichi/Skull's counterpart would be none other than the other Skull.

The Rider after Fourze won't continue the numeral pattern started in Decade.
