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.
