History EldritchAbomination / LiveACtionTV

* Alveus/Hive from ''Series/AgentsOfShield'' is a human who's become a borderline Eldritch Abomination. He's a HiveMind being who's [[TimeAbyss impossibly long-lived]] (he went through his transformation during the Ice Age), can disperse himself in the form of small sand-like insects, and and can possess corpses and living humans with superpowers. His possession acts more like drug addiction, warping human minds into thinking they ''like'' working for him. He does this partially because his true form is a creepy monster resembling a fusion between Cthulhu, a human, and an insect. He's insanely powerful, capable of reducing a roomful of humans into charred skeletons in a matter of seconds and shrugging off any attacks that don't involve fire or electricity. He's also a MergerOfSouls and retains the personalities and memories of every person he's ever possessed. He's not really evil, just [[BlueAndOrangeMorality extremely out of touch with how people actually feel]] and his EvilPlan is ultimately just a desperate attempt to [[IJustWantToHaveFriends feel some kind of connection to mortals once again]].

* Some [[MonsterOfTheWeek Monsters Of The Week]] from ''Franchise/UltraSeries'' fit this trope. However, these are SuperHero shows that [[DidYouJustPunchOutCthulhu punch out Cthulhu]] on a weekly basis.
** Notable is ''Series/UltramanTiga'', where [[Franchise/CthulhuMythos Ghatanothoa]] appears as the BigBad.
** ''Series/{{Ultraman}}'' feature Bullton, an amorphous "creature" which [[RealityWarper mess with time and space]]. A room become loop, inverted gravity, warping stuffs...a mundane facility become EldritchLocation by its ''mere present''. Worse, what appear to be Bullton is really a projection created by two small meteor fragments.

** Greeza, the BigBad of ''Series/UltramanX'' fits this trope to a T. It's most basic form is nothingness as in '''a blank spot in the universe''', but as it absorbs life ([[OmnicidalManiac its sole purpose]]), it gains a more humanoid form with a yellow faceless head and purple skin. Its form constantly wavers, warping reality and space-time as if it's a walking spatial anomaly. Its presence creates what is known as Dark Thunder Energy, which turns peaceful {{Kaiju}} into raging beasts, increases the power of dangerous ones, and harms Ultramen. It absorbs other life forms into its body using tentacles of energy, favouring {{Kaiju}} as its appetizers to absorb their powers. Not helping is its "roar" is a series of psychotic giggles.

* In the {{Garo}} SequelSeries ''Makai Senki'' we are given Gajari, a being that despises humans and [[MonsterOfTheWeek Horrors]]; however, we never truly see what he is except for a head, and apparently his physical body is located somewhere in ThePromisedLand; from the look of his non-physical form he might qualify as this.

** Glorificus, better known as Glory, of season 5. Sure, we saw her as a HumanoidAbomination, but that's just because she was a SealedEvilInACan. She's a ''hellgod'' and was so horrific that other similar gods sealed her and banished her from their dimension. Even in this form, she's an unkillable monstrosity that rips out and ''eats'' the sanity from people unfortunate enough to run into her.

** The Mayor plans to become one.

*** [[TheVirus The Borg]] can be considered one to an extent, regardless of being a technological example, having assimilated countless races and technologies in the Delta Quadrant over the course of centuries, stripping them of all individuality and adding them to [[HiveMind their collective]], travelling in [[SinisterGeometry giant cube-shaped ships]] that are nigh-invulnerable to conventional weapons. And it wants to do this to all races in means of obtaining perfection.

* {{Darkseid}} appears in the last season of {{Smallville}} and he's possibly even more of an EldritchAbomination in the show than in the comics. Rather than being a physical being, Smallville's Darkseid is a living cloud of hate, capable of [[DemonicPossession possessing]] and/or [[BrainwashedAndCrazy corrupting]] anyone who isn't "pure of spirit". He's even capable of [[spoiler: bringing the dead Lex Luthor back to life]]. He's also the [[{{Satan}} Beast of Revelations]].

* "Bill" from ''Too Many Cooks'', who chases characters out into the set, tracks them by their above-the-line credits, and replaces them, sometimes several at a time. His above-the-line credit is a blur.

* Already touched upon in the Literature section, but the made-for-TV film adaptation of ''TheLangoliers'' is pretty traumatizing if you had the misfortune of seeing it as a child.

** '''Death'''. Initially introduced as one of the Four HorsemenOfTheApocalypse, he reveals when Dean meets him that while this is true, he didn't join voluntarily nor was he created for the purpose (implication being that the other three are one of the two), but was bound by Lucifer. [[spoiler:He then gives Dean his ring-the key to defeating Lucifer]] because he considers it an insult to be bound by someone as far beneath him as Lucifer is. In the same conversation, he reveals that he [[TheFogOfAges can't remember]] if he's as old as {{God}} or ''older'', and that he will [[KillTheGod kill God]] in the end. Before he appeared, his scythe was introduced and shown to be capable of killing reapers, something supposedly impossible. "Appointment In Samarra" heavily implies that he's TheOmniscient, though he seemed surprised in a later episode that [[spoiler:Sam and Dean wanted him to kill Castiel]] so how exactly this works is unclear. In "Meet The New Boss", when Bobby protests that they can only [[spoiler:open the door to Purgatory[[ during a solar eclipse, Death calmly replies that he'll just make one.

* True form Angels in ''Series/{{Supernatural}}''. Physically, they (to each other) meet the descriptions of them in religious literature. People who look at an angel in his true form have their EYES BURNED OUT. They inhabit human vessels to be able to interact with other humans safely, however.

** Leviathans and other creatures from Purgatory. They are even referred to by H.P. Lovecraft and by Death himself as Old Ones, and Lovecraft was actually killed by one of these things he had been writing about. Their true form happens to be some form of tentacle monster. We're never actually shown their true forms, but they can slaughter ''angels'' without breaking a sweat.
** The "Mother of All" qualifies, in that she can disable angel powers, see and hear everything through her children, and custom-build monsters (including hybrids like Jefferson Starships). She's the creator of all of the Purgatory residents above except for Leviathans. [[spoiler: The boys had to time travel to find something to kill her, but that probably just sent her to Purgatory, and we know she can get out again.]]

** Species 8472, [[IHaveManyNames also known as the Fluidians, the Groundskeepers, and the Undine]]. Nine-foot tall tripod creatures who come from a dimension known only as [[EldritchLocation "fluidic space"]], have a triple-helix genetic structure and immunity to just about every pathogen they encounter. They use [[OrganicTechnology organic vessels]] that, when linked, have the power to [[EarthShatteringKaboom destroy planets]]. They don't sleep, they don't eat, can survive in the vacuum of space, communicate with telepathy (being on the receiving end of which is MindRape ''squared''), and [[ArsonMurderAndJaywalking have five]] [[BizarreAlienSexes sexes . And for the love of God, ''do not let them [[BodyHorror touch you]].'' The first race to encounter them were the Borg, a race that nearly wiped out humanity with a single ship. They introduced themselves by attempting to assimilate them. Species 8472 '''''[[TheWorfEffect wiped out]]''''' entire fleets of these ships, and left the Borg begging [[Series/StarTrekVoyager Voyager]] for [[EnemyMine help]] in the face of being wiped out. In helping the Borg just to survive, [[NiceJobBreakingItHero Voyager made them regard humanity and the Federation as threats]], which Voyager discovered when they found a perfect replication of Starfleet Academy staffed with members of 8472 near-perfectly imitating humans.

* ''Series/TheXFiles'' has an episode involving a series of disabled teenage girls turning up dead... from apparent electrocution through the tops of their skulls. They turn out to be Nephilim (the offspring of Angels and humans) and they were killed by a Cherubim sent to bring them back to Heaven. He did this by dropping the illusion he created to protect mortals. His true form is so horrifically beautiful that to see it is for one's soul to be taken directly to heaven.

* In ''Series/{{Lexx}}'', the Queen Satellite Worm is immense, obscured by darkness in its underground layer, with glowing tentacles and the ability to shapeshift and take over the minds of humanoids. Its goal is to expand its colony by any means necessary, and humans are simply food to it. We never see it in its full true form, always obscured by shadow, but what was shown was very Lovecraftian.

** And then there was the Medusan ambassador Kollos, who no one could look at without special glasses or else they would be driven mad. Spock went temporarily mad from just an instant's glance following a mind-meld with it. Dr. Miranda Jones could only act as its assistant because she was blind.

** Illyria in ''Series/{{Angel}}'' is from a time when the world was ruled by those like her, who saw (and caused) the deaths of innumerable lesser beings and casually travelled between all dimensions, and dismisses the {{Bigger Bad}}s as inconsequential. Before she was {{De Power}}ed literally nothing the heroes could do even scratched her, and she only abandoned her attempts to reclaim her domain because, essentially, she got depressed. While she spends her appearances in the series [[spoiler:possessing Fred's body]], her true form is seen in ''Angel: After the Fall''.

** The First Evil, the origin of all evil in the Buffy-verse, that existed "before man, before demon", and is said to be within every thought and being in existence.
