History Monster / Nasuverse

* ''VisualNovel/FateStayNight'': [[TheWormThatWalks Zouken Matou]], head of the Matou mage family, is an [[EvilOldFolks ancient, revolting man]] who has long since forgotten everything save his pursuit of the Holy Grail and the power it can bestow upon him. [[ImmortalityImmorality Remaining alive]] by [[GrandTheftMe killing and stealing the bodies of his descendants]], Zouken later adopted the young girl [[Characters/FateStayNightSakuraMatou Sakura]] from the Tohsaka family, before using her as a host for magic worms, having them violate Sakura for over a decade. Zouken manipulates his wayward descendant Kariya into fighting the Grail War for him, fully intending on using Kariya as a sacrificial lamb, infesting him with the worms to shorten his life. After Sakura's power became too dangerous to control, Zouken had her adoptive brother Shinji rape her regularly to keep it under control. In the "Heaven's Feel" route, Zouken engineers a great amount of death and catastrophe, provoking Sakura into unlocking her hidden dark side, intending to seize her body as well and finally claim the Grail at long last.

* ''Anime/FateZero'': [[AxCrazy Ryunosuke Uryuu]] is the master of the equally sadistic and twisted Caster, UsefulNotes/GillesDeRais, but lacks the latter's care for [[UsefulNotes/JoanOfArc Jeanne d'Arc]], making him worse by comparison. He introduces himself by sacrificing a child to summon a demon and becomes ecstatic when he watches Caster kill said child. It is soon revealed that Ryunosuke is a SerialKiller of women, children and whole families, whose MO involves luring his victims to Caster, which then proceeds to torture and mutilate them before slowly killing them. When their hideout was discovered and destroyed by Weaver and Rider, Ryunosuke convinces Caster to summon a demon in Fuyuki City River in an attempt to kill even more innocents. Despite [[StrangeMindsThinkAlike forming a bond with Caster]], this is simply a reflection of Ryunosuke's murderous traits rather than any genuine care, which he loudly states on using it to cause death on a grand scale, while he won't have to worry about dirtying his hand. Taking joy in murder, suffering and death, Ryunosuke is one of the most depraved masters in the history of the Holy Grail Wars.

*** [[AxCrazy Beryl Gut]] is a [[Characters/FateGrandOrderCrypters Crypter]] who, in the past, killed both his parents and moved to the city, where his assassinations earned him notoriety from even the darkest depths of mage society. Later recruited by Marisbury Animusphere to kill any deserters from [[Characters/FateGrandOrderChaldeaSecurityOrganization Chaldea]] in exchange for not giving [[Characters/FateGrandOrderMashKyrielight Mash Kyrielight]] a Sirius Light, Beryl later visits her to break her fingers out of a desire to see her suffer. Resurrected by the Foreign God, Beryl later summoned [[Characters/FateGrandOrderMorgan Morgan]] as his servant who would "break the world", while also gaining the affection of Baobhan Sith, whom he would teach magic, allowing her to cast powerful curses that, unbeknownst to her, would rot her soul. Being sent to the Atlantic Lostbelt, Beryl would burn Wodime's Tree of Emptiness and later stab him, mocking his ideals and Wodime being unable to heal his wound. Returning to the British Lostbelt, Beryl creates a variant of the Mors curse to use on humans by experimenting on them, and later manipulates Woodwose into betraying Morgan, kickstarting a series of tragedies that destroyed the British Lostbelt, all for the sake of his excitement for bloodshed.

* ''Literature/FateApocrypha'': [[WickedWitch Celenike Icecolle Yggdmillenia]], amongst the morally ambiguous [[Characters/FateApocryphaBlackFaction Yggdmillennia family]], is the [[BitchInSheepsClothing only one who absolutely has no moral compass]]. Celenike practices blood magic, sacrificing innocents, including children, which she takes great pleasure in. A sadistic dominatrix, Celenike keeps a [[TortureCellar dungeon]] in her spare time where she tortures those who cross her, or just those who catch her fancy for the fun of it. In between missions, Celenike will very regularly torture, [[RapeIsASpecialKindOfEvil rape]] and murder attractive young men, especially homunculi she deems "useless". Celenike also becomes fixated on her Servant Astolfo. After becoming jealous that he is forming a bond with Sieg, a homunculus who has formed an identity, Celenike snaps and uses her Command Seals to force Astolfo to gruesomely murder Sieg just to break Astolfo. Unlike her other family members and many other antagonists from the franchise, Celenike is motivated by nothing more than cruel lust and unrestrained sadism.

** "[[Recap/FateGrandOrderEvent20DeepSeaCyberNirvanaSeraph Abyssal Cyber Paradise, SE.RA.PH - BB Strikes Back: Let's meet in the Digital Sea!]]": The [[Characters/FateGrandOrderBeasts Beast]]-III[=/=]R incarnation of [[DarkMessiah Kiara Sessyoin]] was once an innocent nun and therapist staffed in Seraphix, but after Zepar inhabited her body and whetted her darker personality, [[FromNobodyToNightmare she let herself become much worse]]. Assimilating the Demon God Pillar and throwing it away after torturous servitude, Beast-III R took over Seraphix using her dark charm and charisma, culminating in using its Planetarium to torture 128, near-dead young Masters over and over into summoning Servants that repeatedly killed one another in a recreation of the [[VideoGame/FateExtra Moon Holy Grail War]]. Obtaining enough power to become Beast III-R, the Demonic Bodhisattva, Beast-III R plunged the digitized Seraphix into the Marianna Trench in hopes of reaching the Earth's core, fusing with it, and turning the planet into a horrid perversion of nirvana. Enslaved by her ego and thirst for pleasure, Beast-III R is nothing more than a [[ItsAllAboutMe self-absorbed, narcissistic hedonist who viewed all of humanity as mere tools to satisfy herself]].

** [[CardCarryingVillain Ashiya Douman]], Caster of Limbo and the "Beautiful Carnivore", [[DrivenByEnvy harbored an intense drive]] to surpass his lifelong rival UsefulNotes/AbeNoSeimei that led him to commit numerous atrocities for the sake of becoming all-powerful. Manipulating Amakusa and [[TheCorrupter corrupting]] the Heroic Spirit Swordsmen in the Shimousa ''Epic of Remnant'', he indirectly causes all the mass murder and sacrifices done there as an experiment for his true goals. He later manipulated Arjuna Over Gods in the Indian Lostbelt into accelerating the cycle of destruction and recreation to cause constant misery, death, and suffering for the inhabitants out of sheer sadistic delight. Allied to the [[Characters/FateGrandOrderForeignGodAndForces Foreign God]] and the Crypters, once they're compromised, Douman slips away to Hell Mandala where he repeats many of his deeds from Shimousa upon the new denizens. Creating his own means to become a Beast, Ashiya Douman stopped at nothing, not even constant genocide and the destruction of worlds over time and space, if it meant proving his superiority.

* ''LightNovel/TheGardenOfSinners: Paradox Spiral'' ([[OriginalVideoAnimation OVA]]): [[CardCarryingVillain Cornelius Alba]] is a hyperactive, flamboyant, murderous [[TheArchmage mage]] with a sickening obsession with tormenting and killing his old academy rival Aozaki Touko. Allying with [[BigBad Souren Araya]], Alba assists the man in his horrifying scheme involving the Ogawa apartment complex, entailing the massacre of the residents and then trapping their brains in [[AndIMustScream an unending loop]] of their final days alive and eventual deaths, a crime that Alba proudly brags about to Touko with glee. When Touko's head is severed from her body by Araya, Alba takes her fully-conscious head for himself to molest and torture as he pleases, before crushing her in his bare hands after bragging about his intentions to kill her defenseless protege Mikiya. Alba is killed after brutally beating Mikiya, smashing his head repeatedly into a wall and stomping his head just because of his association with Touko.
