History NightmareFuel / Slayers

** Also, what happens to Hellmaster leading up to his death is pretty disturbing looking (and sounding, with the screaming he does during it). Though he [[KickTheSonOfABitch DID have it coming.]]

* [[BetaBaddie Copy Rezo]] in the novels...he gains some extra mouths on his body to multiply the number of spells he can use at once. Anime? They're on his hands. Novels? [[{{Squick}} They're his eyes. Physically. That's why they're closed.]]

** Rezo's transformation in the novel is quick and implied to be painless as his consciousness merely fades. In the anime, Rezo is conscious, and [[PainFulTransformation screaming in agony]] as Shabranigdo [[DemonicPossession takes over and reshapes his body into a hideous demonic beast]].
* Ragnut Rushavna. A spell that [[BodyHorror turns the victim into a giant hunk of fleshy meat that gets eaten over and over again by snakes.]] [[FridgeHorror It won't stop until the one who cast the spell is detained, quintessentially making the victim immortal.]] Never appeared outside the novels for a reason... It's used on a [[ButtMonkey bumbling sorcerer]] in one of the novels, while the fellow sorcerer who's rivaling him is [[OffWithHisHead beheaded.]] In the anime, they're merely [[TakenForGranite turned to stone.]]

** Then there's the part in the anime where everyone is surprised to see Syragg rebuilt after it's destruction and all of the people who were killed walking around normally. When Sylphiel sees her father again, [[spoiler: he puts her hand on his chest and she notices that he has no heartbeat. He then tells her that Syragg is a literal ghost town with shadows of the fallen citizens who are controlled by Hellmaster Phibrizzo and that their bodies are trapped in a sleep like state in the underworld.]] Things get considerably worse after that when [[spoiler: all of the ghosts attack the main characters, as they make their way to Phibrizzo's lair.]]

** Watching [[spoiler:Eris]] slowly fall and twitch on the ground while lying in a pile of her own blood and then get vaporized was a giant wake-up call to the audience that the show had stopped [[MoodWhiplash kidding around]]. May count as a CerebusSyndrome moment for the show; in the original books, her death was ''much'' less gruesome. Oh, and then an episode later, [[spoiler: LINA]] has the same thing happen to her, making it ''very'' convincing that she might not survive this one....

* The Dragon Slave-that is, a spell so powerful it's a FantasticNuke.
** A worse one, even if PlayedForLaughs: Amelia with the Dragon Slave. Thankfully it was just Gourry's ImagineSpot after Lina explained him just why she wouldn't teach her that spell... But it was still someone getting nuked for ''keeping a coin they picked from the road''.

* There is one scene where Lina and Gourry fight trolls. Swept away by magic in the anime. [[{{Gorn}} The novel goes into extreme detail about their bloody reminants, painted all over the inn's walls.]]

** Ragnut Rushavna. A spell that [[BodyHorror turns the victim into a giant hunk of fleshy meat that gets eaten over and over again by snakes.]] [[FridgeHorror It won't stop until the one who cast the spell is detained, quintessentially making the victim immortal.]] Never appeared outside the novels for a reason... It's used on a [[ButtMonkey bumbling sorcerer]] in one of the novels, while the fellow sorcerer who's rivaling him is [[OffWithHisHead beheaded.]] In the anime, they're merely [[TakenForGranite turned to stone.]]

* In an early episode of the first season, Zelgadis manages a moment of this when he ambushes Lina (who is unable to use her magic because it's "that time of the month") and Gourry with his two henchmen Dilgear and Rodimus. It ends with Lina facing Zelgadis alone, who immobilizes her by catching her shadow and then proceeds to use a spell that effectively electrocutes her into unconsciousness. The fact that Lina actually screams in pain as he does this doesn't really help.

** Then there's the part in the anime where everyone is surprised to see Syragg rebuilt after it's destruction and all of the people who were killed walking around normally. When Sylphiel sees her father again, [[spoiler: he puts her hand on his chest and she notices that he has no heartbeat. He then tells her that Syragg is a literal ghost town with shadows of the fallen citizens who are controlled by Hellmaster Fibrizzo and that their bodies are trapped in a sleep like state in the underworld.]] Things get considerably worse after that when [[spoiler: all of the ghosts attack the main characters, as they make their way to Fibrizzo's lair.]]

** Another great example is [[spoiler:when Hellmaster ''rips out Amelia's soul in front of the rest of the team'' toward the end of NEXT. The voicework in particular sells it in ''both'' languages, with Amelia in unspeakable pain for a few moments before... ''stopping'' in Zelgadis' arms, and then Zelgadis [[RoaringRampageOfRevenge absolutely losing it]]. And not only that, but when this aired Amelia's ContractualImmortality ''wasn't'' guaranteed, so for people watching at the time? Hand-over-mouth horror.]]

* The novel ''The Silver Beast'' follows the story of a cult worshiping Shabranigdo, and most of its members are rather gruesome-looking chimeras. One of them is a skinny beast-like creature with a brain on its back, and both ''are their own person.'' A far cry from [[MrFanservice Zelgadiss...]]
