NINO & Kamen Rider manga
So did you deliberately rip-off the Kamen Rider manga/anime for NINO’s helmet and “Black-Ops” Corps concept or is it an incredible co-incidence that the two are so similar? Worrying about copyright infringement at all? Admit it - the manga/anime influence was just what you were going for to get the kiddies interested in NINO wasn’t it? Think no one would notice?
I think it’s much more likely that somebody involved with that particular Kamen Rider production was influenced by Nova’s helmet, given that it’s been around since 1976.
