Akira Fudo's demonic alter ego Devilman headlines a two minute promotional reel that Toei cut before the 1972 television series went to air, made to show sponsors and broadcasters what an adaptation of Go Nagai's manga would look like. Its background art and sound work do not match the version that eventually aired. The reel sat unreleased for more than forty years and reached the public for the first time on the 2015 Blu-ray collection, so it stands beside the broadcast run as an artifact rather than an entry point.
