History YMMV / TheDemonata

* JerkassWoobie: For some, Nadia.

* DarknessInducedAudienceApathy: Around the middle of Wolf Island, the situation is: [[spoiler:Out of the three main characters, Kernel apparently exploded, Bec is stranded at sea with a near-dead Dervish due to falling for a trap that cost the lives of Beranabus, Sharmila and Kernel, and Grubbs is surrounded by mutated, enhanced werewolves together with Meera, after watching Shark die. Also, Death has grown sapience and is working to destroy all of humanity, and it's strong enough to let Lord Loss work for it. In short: A seemingly unstoppable force wants to wipe out humanity, while nearly all named characters are dead, dying, or in league with that force.]]

* MagnificentBastard: A few. Lord Loss. The Kah Gash. Beranabus.

** Bec's ''[[EatenAlive horrific death]]'' and her [[RealityEnsues failed attempt to endure it with dignity]].

** Beranabus's LastDance and his FamousLastWords.

** Kernel returning home to his parents after being missing for ''[[YearOutsideHourInside seven years]]''. though he'd only been in the demon realms for three weeks. They try to make the best of it but silently resent his return so much that he pledges himself to Beranabus and returns to fight the Demonata for the rest of his life.

** After Juni Swan's [[ImpaledWithExtremePrejudice de]][[StalactiteSpite ath]] , she is resurrected as an AxCrazy undead...''[[HumanoidAbomination thing]].''

** Bec's ''[[EatenAlive horrific death]]'' and her [[RealityEnsues failed attempt to face it with dignity]].

** Kernel having [[EyeScream his eyes stung out]] by the crab-scorpion demon known as Spine. Especially when the monster spits gelatinous eggs into his sockets which hatch crawling multitudes of multi-mouthed maggots which then attempt to eat through his optic nerves and into his brain. Slowly.

* SlowlySlippingIntoEvil: Grubbs does this toward the end of the series after he allows his Wolf side to surface and, in his words, "becomes a mix of a human, magician, wolf and Kah-Gash." These acts range from allowing Antoine Horwitzer to be slaughtered to ripping out Kernel's eyes because he refused to help with Grubbs' cause. He gets better though.

** What stands out particularly is the ending to the book ''Bec'', where the titular protagonist/narrator gives a rather detailed description of the various demonic beings she is surrounded by while trapped in a tunnel underground, as the light fades into darkness. And then gives a very graphic description of the sensation of being eaten alive by the various creatures (with claws, teeth, beaks and tentacles), with the implication that the last thing she ever hears is the sound of her own screams in the dark.
** In another incident, a guard fires two bullets at a demon lady, who proceeds to stop both bullets in mid-air, transform them into demonic butterflies, and return to sender. More specifically, [[EyeScream his eyes]], and from there, his brain. Slowly.

** Grubbs' misery at having never apologised to his sister for the cruel rat guts prank before she's slaughtered by Artery. This sends him into a massive downward spiral of depression in the institute where he is committed and nearly becoming catatonically insane.

** Bec's ''[[EatenAlive horrific death]]''.

** Grubbs' misery at having never apologised to his sister for the cruel rat guts prank before she's slaughtered by Artery.

** Bec assuring Grubbs that she doesn't believe for a second that he is destined to destroy creation, despite it being prophesied by Juni. Grubbs is so overwhelmed by emotion that he [[{{Glomp}}sweeps her up in his arms]], sobbing.

** Bec confronting Dervish about his lack of care for her. After six months of living with him, he has only spoken to her so he could relive every moment of Bill-E's life through the memories she absorbed. Bec breaks down in tears at the fresh pain of loneliness after centuries without hope, Dervish is weeping in self-recrimination and pity and just when it seems that they will be reconciled; [[YanktheDogsChain the manor is attacked by werewolves]].

** Also Beranabus' LastDance.
