is a shōnen manga series created by Shotaro Ishinomori which first appeared in Weekly Shōnen Magazine in 1970. The hero of the story, whose parents have been murdered, grows up to use his peculiar powers to take revenge. The original Skull Man was one of the first antiheroes to be seen in manga, someone who would sacrifice the lives of innocents in his quest for vengeance. While developing the Kamen Rider (Masked Rider) TV series along with producer Toru Hirayama, Ishinomori created this manga as his own personal version, which the producers at Toei Company Ltd. used as the basis for the show. They made several changes to the content, as Ishinomori's original 100-page one-shot story was too dark and gruesome (even cerebral) for a show for all ages at the time. In the late 1990s, after he had fallen ill, Ishinomori contacted manga artist Kazuhiko Shimamoto to do a remake (ambiguously a continuation) of his original one-shot manga. This remake boasted an extensive, continuing storyline and more complex artwork (along with a tribute to Ishinomori in the final issue, with several of his famous characters gathered together). This was the manga that was presented in the US by Tokyopop. The original 1970 version was digitally released in English by Ishimori Productions in 2012. An animated TV series adaptation, produced by Ishimori Productions and animated by Bones, was broadcast on Fuji TV from April 28, 2007 to July 22, 2007.
