* In the ''Literature/DoctorWhoTheNewAdventures'' novel ''Legacy'', Atissa, the High Priestess of Aggedor, starts of as an isolationist and a bit of a fundementalist, but with ''fairly'' measured disaproval of Peladon's place in TheFederation. When she finds [[spoiler: the dead body of her mother]], she snaps completely, and accuses the Doctor of the crime. When the Doctor points out he has no motive, she says that his motive is that he's an alien and aliens are evil.

* In ''VideoGame/MassEffectAndromeda'' we have the Roekarr which is an angaran terrorist organization that wants to kill all aliens in the Helius Cluster, both kett and milky way. It was founded by Akksul who after a year in a [[BeingTorturedMakesYouEvil kett labor camp]] when from one of the angara's [[TheParagonAlwaysRebels best and brightest]] to charismatic killer convincing hundreds of his kind to hate anything non-angaran, while they hate all aliens they usually end attacking the Initiative because unlike [[TheEmpire the kett]] they lack the numbers, resources and weaponry to properly defend themselves. They also kill angara willing to [[WithUsOrAgainstUs consider the Initiative as allies.]]

* Fanfic/IsseiTheGamingGear has the Purifiers, a group of humans who want to eliminate all supernatural beings - even fellow humans who have spiritual power or Sacred Gears.

* ''WesternAnimation/TheOwlHouse'': [[Characters/TheOwlHouseEmperorBelos Belos]] utterly despises the very existence of the inhabitants of the Boiling Isles. It doesn't matter how zealously loyal they are to his cause, he sees them all as savage and barbaric monsters to be mercilessly slaughtered without any hesitation. In "[[Recap/TheOwlHouseS2E16HollowMind Hollow Mind]]", he justifies his attempted genocide by stating that he is trying to save humanity from evil, even though ''[[{{Hypocrite}} he]]'' wouldn't hesitate to kill humans for suggesting he's wrong about witches and demons, '''including his own brother'''.

** Among non-standard empires, {{Hive Mind}}s can pick the [[HordeOfAlienLocusts Devouring Swarm]] civic and spend the game trying to eat every other lifeform in the galaxy, or in a [[SiliconBasedLife Lithoid]] species' case, eat every other ''planet'' in the galaxy. Meanwhile, a Machine Intelligence can define itself as a [[KillAllHumans Determined Exterminator]], a former defense system that [[AIIsACrapshoot went rogue]], [[RobotWar nuked its creators]], and is now out to kill all organic ofe in the galaxy. As with Fanatical Purifiers, Devouring Swarms and Determined Exterminators can't conduct normal diplomacy (though the latter can treat with other Machine Intelligences, at least) but gain boosts to war production and weapon damage to compensate.

** Xenophobia is one of eight ethical directions an empire can take, with a normal and fanatical level of devotion to it, which can combine with other ethos and result in a variety of AI personalities, from Pacifist-Xenophobes who [[HiddenElfVillage try to stay out of galactic affairs]] to Authoritarian-Xenophobes who want to enslave the rest of the galaxy. Then there's the "Fanatical Purifier" personality, Militarist or Spiritual Fanatical Xenophobes that [[HardCodedHostility can't conduct peaceful diplomacy with other species' empires,]] and generally do their best to kill everything else in the galaxy. Disturbingly, there's no restrictions on government type for this personality, so it's entirely possible for such an empire to be a democratic "Purity Assembly" whose citizens come together in free and fair elections to decide how best to exterminate all the lesser races of the galaxy.
** Among non-standard empires, {{Hive Mind}}s can pick the [[HordeOfAlienLocusts "Devouring Swarm"]] civic and spend the game trying to eat every other lifeform in the galaxy, or in a [[SiliconBasedLife Lithoid]] species' case, eat every other ''planet'' in the galaxy. Meanwhile, a Machine Intelligence can define itself as a [[KillAllHumans "Determined Exterminator,"]] a former defense system that [[AIIsACrapshoot went rogue and nuked their creators]], and is now out to kill all the other organics in the galaxy. As with Fanatical Purifiers, Devouring Swarms and Determined Exterminators can't conduct normal diplomacy (though the latter can treat with other Machine Intelligences, at least) but gain boosts to war production and weapon damage to compensate.
** The Contingency end-game Crisis is an AI programmed to periodically wipe out all galactic life, whether organic or synthetic. It holds that any intelligent life has the ability to cause a "Class 30 Singularity" and so must be destroyed.

** The Daleks would like nothing more than to exterminate all non-Dalek life, and even remake the universe itself to serve Dalek purposes alone. They were created by Davros as a means of ending a [[ForeverWar centuries-long]], hopelessly stalemated war between the Kaleds (his people) and the Thals. Davros programmed them to "survive" by any means necessary, having decided, based on the endless war, that the only way for any one species to survive is by completely subjugating all others. The Daleks are so insanely xenophobic that they hate each other and themselves almost as much as everyone else. They have been known to start civil wars over trivial differences, one commits suicide in the new series when it discovers that it has been tainted with foreign DNA, and a new faction can't stand its own existence because they were created by the Emperor using human cells, making them even nuttier than usual. When said faction manages to create "pure" Daleks again, the former immediately and ''willingly'' allow themselves to be exterminated by the latter. Even the Cult of Skaro, specifically intended by the Daleks to be individuals and consider new ideas, turned on their leader when he favoured becoming "less Dalek" in order to ensure the survival of their race. How does a Dalek say, "[[Recap/DoctorWhoS35E2TheWitchsFamiliar You are different from me]]"?

* Pretty much '''''everyone''''' in the universe in ''Literature/TheThreeBodyProblem'' is this, with alien civilizations unanimously subscribing to The Dark Forest Theory which follows the law of the jungle to the absolute extreme: if you reveal the location of your civilization to the wider universe for any reason; [[DoUntoOthersBeforeTheyDoUntoUs than someone out there will perceive you as a threat that needs to be exterminated]]: regardless if you were benevolent or not. [[spoiler:The Dark Forest way of thinking seemed to have been around as far back as when the Universe first sprouted sentient life: back when the Universe existed in 10D, only for subsequent wars being waged between galactic civilizations to result in the upper seven dimensions to slowly collapse into nothingness, and that the 3D Universe that we currently exist in is on its' way to being destroyed halfway through the story.]]

* ''Literature/SpaceAcademyDropouts'': The Notha consider all other races in the galaxy to be sapient animals at best and engage in slavery as well as genocide. This is speculated to be due to the fact they evolved as tiny omnivores on a DeathWorld and are massively overcompensating.

* Arthur Maxson's chapter of The Brotherhood of Steel in ''VideoGame/Fallout4'' is dedicated to completely eradicating every form of intelligent life in the Commonwealth aside from naturally born humans -- this encompasses synths, non-feral ghouls, and supermutants. They speak of this desired genocide as a just and necessary goal, and even finding out that [[spoiler: one of their best soldiers, Paladin Danse, is a synth who was unaware that he was a synth at all until he was told]] doesn't give them pause as to whether or not what they're doing is right.

* [[Wiki/SCPFoundation SCP-682]] finds all Earthly forms of life [[HumansThroughAlienEyes disgusting and abhorrent]]. Thus, it [[OmnicidalManiac tries to kill anything it comes across]]. The Foundation has been working on figuring out how to kill it first...[[NighInvulnerability without much success]], since it has a powerful HealingFactor and [[AdaptiveAbility promptly adapts to anything it's exposed to]]. Curiously, there's ''one'' thing 682 did not attack on sight: SCP-053, an [[CreepyChild apparently normal human child]] who any person who is around her for more than about a minute will attempt to murder. Much to the confusion of the Foundation, they got along famously.

* The goal of the [[FantasticRacism human-supremacist]] Rebels in ''VideoGame/FTLFasterThanLight'' is to destroy the various alien species and establish a new galactic society for humanity.

* The Glomdoring Commune of ''{{VideoGame/Lusternia}}'' subscribe to this notion. It's their ultimate goal to seed [[TheLostWoods the Glomdoring]] throughout the rest of the known world, while forcibly converting the other civilizations to their [[DirtyCommunists own viewpoint]] as they do. Resistance results in death.

** That said, the Kzer-Za are perfectly willing to find a new homeworld for races who have lost theirs (e.g. Syreen). It's a matter of PragmaticVillainy for them - they can't afford to have a fleet of potential enemies flying around, and destroying an entire race is not an option for them. Their doctrine is also easier to accomplish than the Kohr-Ah's because if you know you're going to die anyway you'll pull a LastStand or TakingYouWithMe. Although the Shofixti [[HonorBeforeReason did the latter anyway]], so that doesn't always work. Also, both factions/subspecies are incredibly polite.

* Certain eras of the ''Literature/XeeleeSequence'' by Creator/StephenBaxter present the rather disquieting specter of ''humanity'' acting this way to everything else, essentially out of a deeply psychotic sense of SiblingRivalry stemming from our second-place status to the Xeelee. Being enslaved by two alien races, the latter of which methodically wiped out all records of human history, also probably didn't help.

* In ''Series/{{Supernatural}}'', Lucifer is the most evil of the archangels, and [[FantasticRacism supremacist]] even by their standards (even the "good" celestials are fundamentalist racists who want to sacrifice half of the 'maggots', i.e. mankind, in the Apocalyptic showdown). His end goal is to use the Apocalypse to wipe out all of humanity [[ItsAllAboutMe because they became God's favorite children instead of him]]. The demons are minions he created himself to be fiercely loyal to him and further his plans, but he actually despises them even more than humans, and plans to [[YouHaveOutlivedYourUsefulness kill them all afterwards]]. He considers the other gods besides his father abominations and murders most of them personally. The only major group he doesn't a''ctively'' plan to exterminate are the monsters, but then he never has any interaction with them, and considering his opinion of God's other creations it's likely not a positive one. (Lucifer may just be indifferent to the monsters because they aren't actually God's creations, they're [[OneBadMother Eve's]] ([[NamesToRunAwayFromReallyFast Mother of All Monsters]]) children.) He wants angels alone to rule and inhabit Creation and tries to tempt multiple celestials to join him. He finally takes it up a notch in season 13 when, during a VillainousBreakdown, he decides to [[OmnicidalManiac annihilate all life in the universe]].

** Wowbagger the Infinitely Prolonged could also count. Rather than wanting to wipe out all other life, he simply wants to insult it. All of it. In person. [[UpToEleven In alphabetical order.]] Being immortal in a universe that allows time travel, it's actually entirely possible for him to do so. (Assuming he really is going in order, he's worked his way through about 15% of the task when we meet him!)
