[Guyver Spawn]

Well they did a Kamen Rider anime as SD Kamen Rider. I think a Kamen Rider anime would work as a OVA series. A anime TV series would never work seeing that Toei does want two shows and two toylines going on at the same time.

My idea for a Kamen Rider anime is either adapt the 1971 manga similar how the Android Kikaider anime was from 10+ years ago or adapt some of the Heisei novels. Some fans may worry that Toei will do a bad job on the animation since they are known to be cheap with animation (See Sailor Moon Crystal and Dragon Ball Super). I think with enough time and money, they can pull it off.
