Essential viewing for Devilman completists and dark fantasy enthusiasts; extremely not recommended for the faint of heart.
While Amon: The Apocalypse of Devilman deviates significantly from the original manga’s ending, it captures the spirit of Go Nagai’s work: the idea that the "Devilman" is a creature born of human sorrow and demonic strength. It served as a major influence on future dark fantasy anime and remains a cult classic for those who prefer their horror unfiltered.

Amon: The Apocalypse of Devilman remains a pivotal work in the seinen (adult male) demographic of anime. It demonstrated that animation could handle themes of nihilism and psychological horror with the same weight as literature. It paved the way for later, more mainstream deconstructions of the superhero genre, influencing works like Neon Genesis Evangelion and Devilman Crybaby .
What makes this OVA essential viewing is how it handles the relationship between Akira and his internal demon. It explores the idea that to save humanity, Akira had to sacrifice his own soul—only to realize that humanity might not have been worth saving in the first place.
