Are all series connected?
 

So i originally thought all the series had nothing to do with each other. With the exception of movies which just didn't care about continuity. And ignoring Decade because that was his shtick.

But are the series connected? Are only some series connected? Or all they all separate?

I always considered Kamen to be like Sentai, where every series is a continuation of the last one. Maybe soon they'll be a Gokaiger-like Kamen Rider :o

Decade is the Kamen Rider equivalent to Gokaiger. Apparently the Heisei Riders are all separate series. Only crossing over in specials that ignore continuity. Decade visits dimensions with those Kamen Rider though. Only Showa era riders had actually any continuity connections to each other.

showa series, ichigo-rx are all connected. kuuga-kiva are all seperate. even the movies for ryuki-kiva are not even kanon in their own series. except of den-o. as for decade onward. i think the jury's still out on that.

^Pretty much what he said, though with the exception that Agito is a sequel to Kuuga.

Every sentai is not a continuation of the last one. What gave you that idea? If you mean what you saw in Gokaiger, that was done that way for the Anniversary show. There has only been two instances where two different sentai's were in the same universe series wise. The VS movies are also AU.

I think it's safe to say that W, OOO, and Fourze are broadly in continuity with each other - I'd actually interpret the recent appearances of the older Riders as a strong implication that the various Rider shows are gradually being merged back into one cohesive, if fairly loose, continuity.

What's the other one? I know about Denjiman and Sun Vulcan, but hadn't heard that another pair of shows were connected.

Kuuga-Ryuki are connected Faiz-Kiva are separate. Decade tried to combine the worlds buuuuut yeah, that show gave no answers to anything at the end lol!

I see the Kuuga-Agito connection, but they're connected up to Ryuki? Explain! lol

I have heard that Ryuki is in the same universe as Kuuga and Agito... Might not make complete sense but I think it's a neat concept, but anyway, here's how I see it, all the Showa shows and W, OOO, and Fourze are one universe, Shin, J, and ZO are one Universe, Kuuga, Agito, and possibly Ryuki are one universe, and then the rest are their own universes, specifically for that series.
