I try not to care. But I guess the Neo-Heisei riders are at least in-continuity with eachother, except maybe Gaim.

Showa: 1971 - Black RX
90's Rider movies: Shin, ZO and J
Kuuga/Agito: Showa, Kuuga and Agito
Neo-Heisei: Showa, Kuuga, Kiva (Going by Ryoma's computer) and W-Drive
Stand alone: Ryuki - Decade

The PS2 Agito game is supposed to be canon going by the game's website but some fans take it with a grain of slat.

Original - Zx, Rx, and W-Drive
Black
Kuuga
Agito
Ryuki
555
Blade
Hibiki
Kabuto
Den-O
Kiva
Decade

I find it hard to believe for all of the rider shows exist in the same world seeing how some of the shows ended like Ryuki and Kabuto.

I haven't seen Ryuki so I don't know how that fits into everything. I don't see why All the original riders can't exist with the current ones minus any planet altering shit like Kabuto's world. Though I can believe that Decade created a brand new created universe.

I also believe Black and Black RX are the same person, and probably has some ability like a split form to be both like something out of the Black RX special. I mean OOO was able to become all of his forms in a movie.

From what I can remember, Kabuto had Tokyo wipe out completely. I would find it hard to believe that the city return back to normal like a week later in Den-O if they all exist in the same world.

I like to think Ryuki-Kiva all are different worlds that sometimes interconnect with each other.

hence why the original 3 were able to enter freely in the Gaim world.

and yes, Kuuga and Agito are both in the same universe.

Ryuki has time problems so yea. But I suppose Decade or Den O honestly could just connect everything with each other if they wanted too.

I feel like Ryuki can be fudged into the Kuuga/Agito timeline. The story of Kanzaki's doesn't really conflict with anything from Kuuga/Agito, at least not to my knowledge, and it could even explain some of the supernatural elements of the series.


Kabuto, well, yeah, there's really no way to explain the destruction of Tokyo and then it being rebuilt a week later for Den-O. Maybe Tendou just did Kabuto shenanigans to prevent the destruction altogether but eh.

Well it is Tendou I mean he went back in time to help himself who knows what he could do.
