Yes, Battle Fever J was a long-ago co-production between Marvel and Toei, the show that kicked off the sentai live action team series in Japan. But I expect any interest we had in the show is long since gone–I believe Marvel was out before it even made it to air. (Originally, it was meant to be a show with Captain America in it, but as it changed and became more Japan-centric, the character morphed into the very strange Miss America.)
