History YMMV / HellboyAnimated

* CompleteMonster: [[SerialKiller Erzsebet Ondrushko]] from ''Blood and Iron'' is an [[AristocratsAreEvil evil countess]] based on the infamous UsefulNotes/ElizabethBathory. Consumed by her vanity and wishing to [[ImmortalityImmorality stay young and beautiful forever]], Ondrushko sold her soul to Hecate, the Greek Goddess of Witches. In return, Hecate transformed Ondrushko into [[OurVampiresAreDifferent a vampire]] and gave her the power to rejuvenate her body if she [[BloodBath bathes in the blood of young women]]; she is said to have murdered over a thousand people in her quest to remain young. Through a series of flashbacks, we see Ondrushko take over a dress shop, by murdering the shop owner and her [[WouldHurtAChild infant child]], to lure in and kidnap a young girl named Anna. Anna's fiancé gathers a rescue party, including a young Professor Broom, which goes to Ondrushko's castle, which is filled with torture devices and the bodies of young women. Finding Anna drained of blood, they [[MercyKill kill her to prevent her from becoming a vampire as well]]. Ondrushko kills most of the rescue party, but Bloom manages to kill her. Though her body died, her evil spirit remained. Sixty years later, the BPRD is sent to investigate a supposed haunted mansion, which is in fact haunted by the souls of Ondrushko's many victims. Ondrushko's minions resurrect her and she bathes in the blood in the mansion's owner to rejuvenate herself.

* ValuesDissonance: Many Western viewers don't understand why the Samurai's actions in ''Sword of Storms'' shamed his Daimyo. A brave hero who rescues a fair maiden from evil demons and spares his liege lord the horrible choice between sacrifice and destruction is the foundation of European Legends and Fairy Tales. Such deeds usually earns the hero a reward--the maid's hand in marriage or a lordship of his own, not being turned into a statue and his love murdered by her own father.

* WhatDoYouMeanItsNotForKids: The animated films are in no way child-friendly, and, in some ways, are actually much DarkerAndEdgier than even the live-action films. Creator/CartoonNetwork airing the films during then kid-friendly Creator/{{Toonami}} block didn't help much either. To their credit, however, some of the more violent content was edited out of the film and it did air with a TV-14-V rating, with {{Content Warning}}s.

* SugarWiki/FunnyMoments: Hellboy's reaction when he learns of the nukekubi's intention of eating him. He reacts (not with fear and horror) but with disgust and disbelief, as though they were merely going to pull a gross prank on him.
** Later, whilst fighting the demons Thunder and Lightning, Hellboy tries to throw Thunder's own hammer at him, but he misses. Thunder stares at him and then the hammer, as though wondering "Do I fight him or do I get my hammer?", before Hellboy scoffs "Just go get it".

Creator/CartoonNetwork airing the films during daytime hours didn't help much either.
