Devilman

is a Japanese manga series written and illustrated by Go Nagai. The manga focuses on a high school student named Akira Fudo who absorbs the powers of the demon called "Amon" with help of his friend Ryo Asuka in order to battle creatures hidden in human society, thus calling himself the "Devilman" in the process. The series was originally ordered by Toei Animation as a toned-down anime version of Nagai's previous manga series, Demon Lord Dante, although Devilman ended up having a darker tone which reflected Nagai's anti-war sentiments.

Devilmans 39-episode anime series was developed by Toei Animation in 1972, while Nagai began the Devilman as a manga in Kodansha's Weekly Shōnen Magazine, barely a month before the anime series started. The manga was published between June 1972 and June 1973, while multiple publishers have released it in collected volumes (). Seven Seas Entertainment published the English translation of the original manga in two volumes in 2018. The series has since spawned numerous OVAs, manga, novels, films, and a sequel. Devilman and other characters from the series have shown up in cameo appearances numerous times in Go Nagai's other works. The most notable is Tomoharu Katsumata's 1973 feature film Mazinger Z vs. Devilman, which features Devilman teaming up with Nagai's titular robot to fight Dr. Hell. In 2018, a remake titled Devilman Crybaby directed by Masaaki Yuasa was created showing an alternate more modern-like retelling of the manga.
