Devilman is a 2004 Japanese superhero film directed by Hiroyuki Nasu. It is based on the manga series of the same name.

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. However, Nagai wrote a darker-toned manga in order to alert readers of the dangers of the wars based on how dark the narrative becomes with each of Akira's challenges.
