* AnimationAgeGhetto: Unsurprising, knowing most video stores.
** The 1972 anime was aimed to kids, having lots of changes in comparison with the original manga. See LighterAndSofter for more detail.
* CompleteMonster:
** Jinmen, the depraved turtle-like demon eats humans alive to [[YourSoulIsMine devour their souls]], leaving an imprint of them on his shell while they are trapped in agony. Jinmen targets vulnerable humans on purpose, with children being a favorite meal, including a 10 year old named Sachiko who had befriended Akira. Those he devours are left [[AndIMustScream alive and conscious]], but trapped until Akira kills him.
** Amon was a demon that was [[DemonicPossession taken inside of Akira Fudo]] but was eventually trapped inside him, existing as Akira's SuperpoweredEvilSide. When Akira crosses the DespairEventHorizon, Amon finally emerges in the OVA ''Amon: The Dark Side Of Devilman''. Amon murders humans and demons [[ForTheEvulz for his own twisted amusement]] and takes delight in [[MindRape mentally torturing Akira with images of him as Devilman devouring his beloved Miki]] and in one of the most memorably horrifying scenes, when Amon discovers a little girl in rubble, he lifts her up before ''eating her alive'', horrifying even other demons.
** Candy from the AMON side story was a SerialKiller before achieving great power. In the post apocalyptic world, Candy ekes out a power base by convincing humans there is no such thing as Devilmen, resulting in purges of countless peaceful humans believed to be demons. Candy takes delight in the deaths of the innocent and simply enjoys wielding power over others.
* CrowningMusicOfAwesome: the uses of Anthem's "Show Must Go On" and "Light It Up" in the Devilman: The Birth and Demon Bird OVAs.
* EnsembleDarkhorse: Jinmen. For crying out loud, out of all the Characters in this series....He even has a {{MUGEN}} character.
* FanNickname: ''[[UltimateMarvel Ultimate]]'' ''Devilman'' for ''Devilman'' ''Grimoire''.
** Due to a notoriously mistranslated subtitled version of the 1972 anime, DEBIRU-Man has become a popular nickname for the title character.
* FridgeHorror: In ''Devilman Grimoire'', actually. Remember how, in the original ''Devilman'', [[spoiler: Miki and Tare were horribly murdered by a psychotic lynch mob consisting of their own neighbors, because they thought she was a witch?]] When one considers that the cast is pretty much the same in ''Grimoire'' (with a few additions), it stands to reason that the Makimuras' neighbors most likely are also the same people. Which then leads to the realization that the whole neighborhood is a ticking time bomb, ready to go off under the right conditions. It doesn't help that Miki goes around announcing to anyone who's willing to listen that she is a witch.
** Then again, as of the latest chapters in ''Grimoire'', [[spoiler: Miki herself is now a Devilman, so killing her just became that much more difficult.]]
* MagnificentBastard: [[spoiler: Ryo/Satan]]
* MagnumOpus: Go Nagai considers the franchise to be his best work.
* MemeticMutation: [[http://blogofthenorthstar.com/wp-content/uploads/2012/05/devilman_v01c01_p028.jpg MY FATHER DIED!]]
** [[http://blogofthenorthstar.com/wp-content/uploads/2012/05/drugs.jpg Oh, this? It's laced with drugs.]]
** And of course.....[[http://i1098.photobucket.com/albums/g370/roman551/vlcsnap-2012-05-13-10h14m15s147.png DEBIRU-Man]]
* {{Narm}}: Satan's immortal line: "For, you see, I am a hermaphrodite!"
** The Live Action Movie is filled with this.
** Ryo's plan for turning Akira into Devilman involves gathering a bunch of hippies together in his basement. ItMakesSenseInContext, yes, but it's hard to take the line "These people here are rouge hippies I've gathered together" seriously.
* SnarkBait: The Live Action movie, which was the winner of the first Bunshun Kiichigo Awards (The Japanese answer of the GoldenRaspberryAward)
* SomeAnvilsNeedToBeDropped: The story is genuinely a criticism of militarism and how fear and hatred bring only tragedy.
* SpecialEffectsFailure: The movie version suffers from this.
