Would anyone else be interested in a sibling rider duo?
 

You know, something along the lines of Kick and Punchhopper from Kabuto(they technically aren't brothers, but the example still works) or Go-On wings from Go-onger. I think this can really bring something really unique to the table, both in battle and as characters, so I'm a bit surprised how under utilized the idea is.

I think it's because they prefer more antagonistic partners in KR.

I could see them working less as primary and secondary Riders, and more as third and fourth Riders.

Thats what I was thinking as well. When I suggested the idea, I didn't mean as the primary and secondary rider.

Didn't we already get this though with W?

And Gaim with Ryugen and Zangetsu.

No, because Shotaro and Philip aren't biologically brothers. I think that's what macblo is getting at.

But Kamen Rider also prefers drama, and antagonistic siblings is like, the cheapest kind of drama you can get.

We did sort of see this explored with the Kureshimas (who do appropriately fill out the 3rd and 4th Rider roles). Though that is like the one example.

As long as one of the siblings is actually female and get’s a lot of focus… sure.

Brothers though? Nah.

When I said duo riders, I was more talking about the link that they and their power share. I was thinking that they could have a yin and yang or fire and ice thing going on, in which there powers are very similar, yet very different. Mentioning that though, Kuuga being similar to N-Daguva-Zeba(the final boss) wasn't a half bad example of what I mean. While this is certainly something that can be had with brothers(or a brother and sister but this is Kamen Rider so...), it was just an example I was giving.
