'''Kamen Rider Black: Hurry to Onigashima''' is the first movie based on the ''[[Franchise/KamenRider Kamen Rider]]'' TV series, ''Series/KamenRiderBlack''.

Released on March 12, 1988 (between ep. 22 and 23) as part of the Toei Manga Matsuri film festival. Originally known simply as ''Kamen Rider Black'' during its theatrical release. Children all over Tokyo mysteriously disappear without warning. Kotaro suspects that the Gorgom are behind the abductions and follows a suspicious-looking tour bus with children on it, only to lose its trail off a cliff. With the help of a fisherman (played by Creator/ShotaroIshinomori himself), Kotaro travels to a remote island and uses his abilities as Kamen Rider Black to save the children and foil Gorgom's latest evil scheme.

After the next episode previews for episodes 21 and 22 of the tv show, a phone-in completion was advertised, giving away a total of 500 tickets.
