Cthulhu Mythos-verse Strategy Guide

How to be OP in The Cthulhu Mythos

Local to Planetary Scale Threat:

This is the tier of the general alien races that inhabit the main universe of the Lovecraft Mythos, mostly having come from another universe. 

In terms of power most of the alien species scale to the Star Spawn of Cthulhu who could withstand the heat of living within a Star, requiring high end multi-city block level durability who did battle against the Shoggoths. This is consistent for the Shoggoths' masters the Elder Things have mastered the power of the atom which should allow for nuclear weapons in the town to city range. There also exists in the Dreamlands living mountains described as hundreds of feet tall which would likely require town to city level power. Overall most of the alien races are multi-city block level+ with the strongest being town to city level. 

In terms of speed this tiers get very fast for it's tier. The Mi-Go were able to quickly travel between Earth and Pluto requiring speeds hundreds that of light at least. The Flying Polps were able to come from an immeasurable distant universe though the timeframe of this event is unknown. Most notably the Star Spawn of Cthulhu were able to travel from the distant star system of Xoth, requiring speeds likely thousands to millions of times the speed of light. This suggests the verse's fighters in reaction speeds would all be atleast thousands to millions, possibly as high as quadrillions or quintillions of times the speed of light (depending on timeframe for Flying Polps).

Some of the fighters aren't the max stats but these are the maxium for the tier so I will use those as limits.  

Long before the age of man, the Elder Things came to Earth and with their advanced intellects and technology created all the species of Earth, for the Elder Things had control over the atom and could form new lifeforms from it.  The Elder Things can fly and have hypnotic control, which they used to control their minions the Shoggoths they created to fight for them.

The Shoggoths are an incredibly disturbing race whose mass shifts and changes. They are known for their rapid change and evolution to the point of developing minds to rebel against their creators the Elder Things. 

Numerous species waged wars against the Elder Things and the Shoggoths in the prehistory of Earth and the Universe. One of these was the Mi-Go, a fungi-like alien species that can duplicate over time via spores, fly through the cosmos and are made of some strange matter that can not be picked by technology as their body does not reflect light in the same way as normal entities. Another was the Star-Spawn of Cthulhu, a species that came from within the stars, a plasma-like lifeforms whose true selves reside in a deeper non-physical universe. These species were relative in intelligence to the Elder Things who had attained mastery over the atom.

The Elder Things also warred with the Great Race of Yith who are far more intelligent then these, for they have knowledge of all things in the universe. The Great Race of Yith are known for projecting their counciousness across time to any entity in the past of future, possessing them, as a way to avoid death. They experience no pain, and their technology includes their famed lightning guns which project electricity and some device which wipes memories.

Their enemies are the Great Flying Polyps. Lacking all normal senses and instead experiencing the world as a series of mental impressions, their minds are so warped and non-understandable that even the Great Race of Yith can not possess them and indeed the Polyps caused the Yithians great mental anguish. They flash in and out of visibility though despite their flight they leave strange 5-pronged "footprints" wherever they go, and are only partly material making them immune to most conventional harm. They are known appearing on a powerful wind current with a distressing whistle sound. 

Beyond these there are numerous other monsterosities hiding in the gaps in man's perception. The colour out of space is a living colour from out of space that infects and corrodes living beings using them as a vessel to transmit and spread, absorbing their essence. From a lower reality then humans are the dimensional shamblers, monsterosities from lower planes who can hypnotize humans, showing them distressing confusing images of their lower reality and if they do not have the willpower to resist, consuming them; body, mind and soul. The halfbreed of Yog-Sothoth and man is the famed Dunwhich Horror, a giant invisible creature that exists outside of the normal physical laws of the universe existing in a higher plane of reality, whose cries cause pain and madness and who can summon the Great Old Ones depending on his area. 

In the dreamland there exists more and strange creatures including the strange moon-beasts who can control their "bodies" freely and the living mountains who appear like wolves and who make no sound whatsoever. This is the world of the Satyr-like men of Leng. 

Perhaps strongest are the Hounds of Tindalos who can pursue any target across time, exists outside time, is immune to force and matter, and can appear in any degree up to 120 degrees. They can also use poison and smoke and can absorb energy.

A lot of the characters in the tier have a weakness of some sort, like the Flying Polyp's weakness to electricity which prompted the Great Race of Yith to take up their lightning guns, but it would be hard for one character to have all of the weaknesses. 

Intangibility seems to be strong in the verse, which is why the Elder Things had difficulty battling the Star-Spawn's whose true selves are intangible and needed the Shoggoths. The Shoggoths and possibly the Polyps have the ability to affect intangible entities physically. Outside that only Dimensional Shamblers soul consumption, the madness inducing sight of the Dunwhich Horror, and the trans-time mental projection of the Great Race of Yith would be able to affect a non physical entity. A being higher then mental would be essentially invulnerable.

Speaking of the Great Race of Yith, their ability to possess people across time requires some response. Being mindless or having an incredibly warped mind might be able to do it like the Polyps did, but that would just cause them to flee through time and is rather limiting. A stronger tactic albeit a rather limiting one would be to exist outside spacetime. 

But general spacetime manipulation would probably be strong and allow exploitation of many of the weaknesses of various alien races in the verse. A character on this tier may not be able to make the stars not right for the Star-Spawn but they could hypothetically bring them to a time when the stars weren't or won't be right. The Hounds of Tindalos can be stopped by a perfectly spherical space as they can travel in angles up to 120 degrees. If time is frozen or reversed this would likely mess up the Hounds of Tindalos and The Great Race of Yith's ability to move backwards. Replicating the atmosphere of Earth with space manipulation can weaken both the Flying Polyps and the Mi-Go both of which were weaker in Earth's atmosphere. Spacetime manipulation also has the added benefit of being able to counter potentially the cosmic speed of the tier.

So a character that exists outside spacetime and is a non-physical entity? Well one good counter with those traits would be 

Drosselmeyer from Princess Tutu

Drosselmeyer's power created the Raven, a being who dwarfed a town suggesting it would be relative in size and power to the Mountains of Dreamland, and Drosselmeyer created them casually. His speed is massively lower however this is essentially irrelevant as Drosselmeyer is an astral plane entity existing outside spacetime and can exist in numerous places in spacetime at once.

Drosselmeyer is a really hax entity with town+ scale plot manipulation who would be able to manipulate the plot to exploit each weakness that exists in the tier, as well as change the plot to cause the very alien species to lose. The Great Race of Yith would not be able to percieve him and he could manipulate the plot so they could get caught up by the Flying Polyps. His willpower was so strong he could come back from death, showing that the Dimensional Shamblers would do nothing to him, even if they did catch up to him. He can also casually bfr enemies into his puppet dimension without spacetime and where anyone is a puppet to him. Being outside spacetime would mess up the Hounds of Tindalos even if he couldn't just plot manipulate them to moving inside of a spherical room. It also helps that Drosselmeyer's personal chamber outside spacetime is filled with mirrors he looks into to see the physical world, which are all 180 degrees that the Hounds of Tindalos would definitely not be able to go through.

The only real threat would be Drosselmeyer's personality. Drosselmeyer can't resist a good story and loves tragedies. It's possible he would let the alien species of the verse go on and create and more and more tragedies. While most of them would not be any threat to him, the Dunwhich Horror due to his descent from Yog-Sothoth himself, could potentially affect Drosselmeyer or summon a being far stronger then Drosselemeyer. For a more efficient counter you could use

Ultear Milkovich from Fairy Tail

Ultear is signifigantly stronger then Zancrow who creeated megatons of damage with his Flame God Bellow suggest she would be relative to the top tiers of the tier. She is also a specter of time existing outside of time and tracks though who move through time almost exactly like a Hound of Tindalos though without the restrictions. Also if she were to fight them, or the Great Race of Yith she can resist time hax as shown by her being able to resist the hax of the God of Time Chronos. 

Her Arc of Time also allows her to change the flow of a person's timeline, which could be used to time hax most of the verse, regressing a Shoggoth to mindlessness before it developed a brain, or progressing a Star Spawn to the point where the stars were not right for them. With her origin release magic she can specifically reduce beings to the weakest they've ever been, which would do something similar.

She can also duplicate herself with her abilities by summoning alternate timeline versions of herself, allowing her to fight against whole species if needed. And while the Yithians would not be able to possess her she can actually possess people which is what made them strong.

That said she may have difficult fighting inter-stellar civilizations and some of the haxes of the verse could still potentially affect her. While she would be really strong against any one or small group of characters, she wouldn't be able to super control the verse at this tier just due to size. The ideal counter for this tier would be 

Danny the Street from DC Comics

Danny is a living city block that can teleport around at will and who provides a home for anyone who needs one. 

Most of the verse's fighters do not have the area of effect to hit an entire city block at once. Moreover, Danny can simply use his massive spatial manipulation. Danny's spatial manipulation is so good that he can create an infinite space within himself if he needs to house infinite people. He could simply teleport in and trap people inside him. The Hounds of Tindalos could be trapped inside of a spherical space within him. The Yithians couldn't possess the flying polyps, it's unlikely that they could possess the abstract mind of a living city block.

Even ignoring that though, Danny can turn into Danny the Ambulance which can save people by always moving fast enough to protect people, even if that involves going back in time or moving a conceptual distance like when he was able to rescue Crazy Jane from Hell or transport Dorothy from the Dreaming. He was also able to move backwards in time much like the Hounds of Tindalos to protect against Milkman Man. He also has creation abilities as within are Danny Comics which can create fictional comic characters which exist in the Dreaming that Danny himself can go to rescue and bring with him. While this would be an NLF (it likely depends on the amount of people he is housing at the moment), it should be versatile enough to create things that could exploit the weaknesses of the tier.

Danny the Street is a character who is motivated personally by the protection of the vulnerable, and whose powers conceptually function on that level, and in a verse as dark as the Cthulhu Mythos, where entire species are regularly in need, Danny would be able to travel infinitely fast across the universes, into the Dreamlands or into the depths of time and bfr-ing any enemy that would seek to threaten the people within him.

Planetary to Universal Scale Threat:

Existing since long before the thing we understand as the universe were the Great Old Ones, the ancient race whom the lesser races take to worshipping as deities. The Great Old Ones in their ancient wisdom have come to spy dimly the great and terrible forces ruling over existence. 

Even a lesser member of the Great Old Ones, the frog-like Ythogtha had fingertips the size of mountains nearly 3 kilometers long, suggesting his size and power would be within the country scale. Another of their kind, Great Cthulhu did survive the sinking of Rlyeh, the total energy of would be in the continental scale. Even taking a small portion of this energy would require country level durability and Cthulhu likely took much more for he is massive such that his form rises above the waves while he is standing on the seafloor bottom.

Amoung their numbers is Atlach-Nach the Spider "Deity" who weaves a web between the physical universe and dreamlands, two seperate deities. Conservatively this would be trillions of times the speed of light and likely quadillions or quintillions of times the speed of light.

The Great Old Ones powers are immense. They knew all things happening in the universe, showing the power of their telepathy. They have existed for Vigitillions of years, a timeframe so immense we seriously can not understand it showing a cosmic level of experience. Mortals who have experienced the Great Old Ones go mad or die afterwards from fright or mysterious circumstances showing their power to affect lesser minds; causing madness, fear to the point of death, or death by other means. They exist in a deeper universe beyond matter, and so any damage to their bodies will not truly defeat them, indeed they shall outlast the physical universe and death itself. 

They also possess numerous individuals powers, often controlling the forces of the world. Great Cthulhu is the most famous of their kind. Cthulhu's sleeping presence was enough to mentally affect people across the world, giving them horrid esoteric dreams and driving the most sensitive of their types mad. When he was awake, the humans who looked upon him were mostly driven mad or died. Great Cthulhu also formed the Great City of R'lyeh likely with some form of reality warping and spatially warped it into higher dimensions such that the geometry of the city was impossible.

His father Dagon is a shapeshifting sea creature who controls all sea life. The spider Atlach-Nach creates metaphysical webs to create a bridge between the universe and the Dreamlands. Horrific Ghatanothoa causes paralysis to all who see it and Gol-Goroth shifts into the worst fear of whomever sees it. 

Jub-Shabb is a magical ball of pure energy which makes it particularly difficult to hurt. The "God of the Red Flux" worshipped in Central Africa turns people into voodoo zombie minions and Quachil Uttaus decays all biological matter near it until they become dust. 

In terms of strategies I think the most obvious one is to keep one's distance. Getting close to Uttaus will decay anything made of biological matter. That said one needs range above planetary to avoid most of the Great Old Ones' effective range and inter-universal to avoid the telepathic awareness of the Great Old Ones. 

Beyond that a lot of the same strategies of the last tier would work; higher plane entities and existing outside spacetime. It should also be noted that the Great Old Ones, especially Cthulhu are noted to go into incredibly long periods of a deathlike sleep suggesting sleep manipulation would be effective even if death manipulation would not be. Also they seem to rely on the stars being right. Cthulhu's awareness was blocked by some primeval mystery of Earth's atmosphere and the position of the stars. 

Generally the best position is trying to nullify the threat of the Great Old Ones by attacking from a higher plane entity outside their gaze, sealing them away or sending them back to sleep with sleep manipulation and time. Staying outside their awareness also helps their disproportionatly fast speeds. My first counter would actually not just be able to stay out of their awareness but actually match their speeds, that being 

Mayura Seno from Alice 19th

Mayura's power is not as strong as the Great Old Ones, though she was fast enough to match the Lotis Masters who could quickly move around to the center of the Heart, an Astral Universe and match the speeds of Dalvia's darkness which can quickly encompass the heart which is again it's own universe.

Inside the heart, Mayura would be invisible especially if she used the Maram Word to disappear into the darkness of the heart Veeta. Mayura can exist within the dimension of the heart, the dimensions representing the individuals emotions. Because of the Great Old Ones' telepathic influence on people across the world, the hearts of each humans would be connected to the Great Old Ones from which she can attack. 

And attack she can. Muduro can curse, causing a negative effect if the conditions are met. It would be fairly easy to curse the Great Old Ones to fall asleep again if they awaken or if the stars are right. She could effectively change when the stars are right. She has Matsu which can brainwash thousands of people which is a more direct mind hax then the Great Old Ones possess. The biological ones of the Great Old Ones could be affected by Byoma which infects with an astral sickness. Most powerful would be Rajika which puts people into a deathly sleep which is exactly what can stop the Great Old Ones. She also has Ramito which seems to revert an entity to when they were weakest which would have the same effect. 

The only threats to Mayura would be that the hearts of the Great Old Ones would be so warped as to cause her insanity or that the Dream Spider Atlach-Nach would be able to affect her despite her existing within the heart. For a character Atlach-Nach would not be able to affect you could use

Kezef the Chaos Hound from Dungeons and Dragons

Kezef the Chaos Hound scales to Father Lyrmic who was able to freeze the world taking country level energy. While Kezef is much slower, it is irrelevant as he is an abstraction of pure hatred. Kezef would be functionally immune to any of the tier's fighters. 

Kezef is most well known for passively nullifying powers, even the powers of the Gods like Tyr whose hand would not regenerate after he bit it off. As the Gods are also abstractions, Kezef can clearly hit intangibles and would easily be able to kill the Great Old One's true selves. 

Kezef is also known for controlling chaos and probability which would make it incredibly difficult for them to hurt him, and even trying to run away wouldn't work as Kezef can teleport to any place in the multiverse. 

The only risks to Kezef would be that his natural corruption aura would turn one of the Great Old Ones into something that could threaten him or that Cthulhu would be able to spatially trap Kezef into a higher dimension, which likely wouldn't work but could possibly. 

For the best counter to this verse, one who literally could not lose no matter what, that being

Jill Presto from DC Comics

Jill Presto is the vessel of the Basanos who manipulate the Fate of the entirety of DC Comics. If any would would be done to her, it is immediatly undone. She as a supernatural luck that means the Great Old Ones trying to do anything to her, is more likely to harm them then her. 

She might be massively weaker in terms of her stats, but she doesn't really use her stats in particular, as her ability is usage of the Basanos to see every single possiblity of something. With this she can cause any possible death to occur to someone, including every single possible death at once. 

The Great Old Ones will outlast death for they are older and more fundamental then the universe. But Jill Presto can see them in every single universe at once, and kill them in every possible way in every single possibility at once. Every single universe where the Great Old Ones are reduced to deathlike sleep would occur at once, permenantly incapacitating all of them.

Universal to Multiversal Scale Threat:

Beyond this simple universe we humans know, there exists realities far more fundamental and terrifying. Here resides the archetypes, the basic forms from which our universe is formed. The fragment of a single human beyond the gate was able to survive the emanation of Yog-Sothoth speaking at him, which was like the destruction of universes. 

Here resides the slave races of the Outer Gods, including the Hunting Horrors of Nyarlathotep who chased Randolf Carter across infinite voids as universes were born and died around them. This is often used as a multiversal feat though the wording does not make me thinh it is as they were chasing him through time, as the great cosmic events occured around them. Also because of surface area it would be much dimished. What it does is show is infinite speed.

So any counter is going to need some counter to literally infinite speed as well as fighting conceptual entities like the Archetypes, each of which having a domain over some aspect of nature, most famously of these being Hypnos, God of Dreams.

These are the Elder Gods, the Gods of Man who are insignifigant to the Outer Gods just as man's understanding of the cosmos is insignifigant to the greater cosmos. The strongest of the Great Old Ones would likely be here as well. 

Of the slave races, two are most well known those beings the Hunting Horrors and the Nightgaunts.

The Hunting Horrors are shapeshifting monsters of darkness that pursue the will of the Dread Pharaoh Nyarlathotep. They are weak to incredibly intense lights. The others are their mortal enemies the Nightgaunts, of the Dreamlands. The Nightgaunts are a flying dream race known for their mind-reading and their....tickling ability. The Nightgaunts tickle enemies into submission. So that's something.

So what would be good here? Well you can't rely on existing outside spacetime as most of the entities here do, and conceptual is a pretty high plane to fight. The one good thing is most of the characters on this tier are fairly simple both in terms of powerset and mindset the slave races being nigh unthinking and the Elder Gods being arrogant and not knowing their place in the cosmos. As such if you can somehow counter the infinite speed and conceptual entities of the plane, someone with decent versatility and a good thinker will likely be able to win. This brings me to my first counter who is famous for both of those, that being

Sun Wukong after attaining Buddhahood from The Journey to the West.

As a Buddha Sun Wukong's palm is the whole universe. He also is much faster then his weaker self who could leap to the edge of infinity showing infinite speed.

Sun Wukong is incredibly versatile, able to duplicate himself once for each hair on his body, which given his incredible size and omnipresnce after attaining Buddhahood would be an almost countless amount. He is 5-fold immortal at least which would be nigh impossible for anyone on the tier to kill.

As a Buddha, Sun Wukong has transcended over most concepts, being the cosmos itself. He was also infamous for his incredible manipulative ability even before becoming a Buddha and becoming nigh-omniscient.

He can also seal enemies as Buddha did to him which he could likely do to the archetypes.

The only threats would be if his sealing doesn't work on the archetypes, he doesn't have much else which could affect a conceptual. For a counter that can more clearly affect a conceptual you could use

 

God of Death Flash from DC Comics.

When Barry and the Black Racer merged they were able to strike through an emanation of Darkseid which was casually destroying universes. Barry can reach infinite speeds able to reach the speedforce which is conceptual levels of speed as can the Black Racer. Black Racer is naturally a concept which shows he could affect concepts like the Archetypes.

Flash has numerous abilities that would absolutely tear through the tier if he can affect them. He can energy-drain on a multiversal scale, he can speedforce dump which none of the tier would be able to escape from outside maybe the Elder Gods. He also combines the superintellect of a New God with Barry's scientific knowledge of the speedforce. 

Speedforce BFR would be especially damaging to the Hunting Horrors since it's where all kinetic energy, including all light the movement of photons, originate. His connection to the speedforce also allows him to nullify kinetic energy and it's aftereffects including scientifically tickling. He can also freeze time which the tier doesn't seem to have, though it's arguable if it would work as they exist outside physical spacetime and it's unknown if the Black Racer's time stop works past the physical.

However he could still be affected and outnumbered by the tier. For a character who I think that would not be a threat, you could use

Bugs Bunny from Looney Tunes.

Bugs Bunny might not have infinite physical speed, but he has meta speed able to exit the page he's on and take metafictional control over the universe. He would need to be stopped immediatly or no one in the verse would be able to affect him. However Bugs is seemingly a normal rabbit that would not get the verse's attention immediatly, and even if they did Bugs is a famously good manipulator who would simply trick them.

Bugs Bunny also has toon regen meaning he can come back so long as people laugh at his cartoon, something the tier would have no way of realizing before Bugs plot haxed them. Bugs in general is massively more versatile and intelligent then the tier, and would manipulate them easily.

He would also be immune to almost anything they could do as he has a supernatural luck, a rabbit luck so strong it even causes bad luck to other lucky rabbits like the Grim Rabbit. He's also acausal on a meta scale as he scales Wily E Coyote who was unaffected by having a page of his story erased.

Also Bugs can also time stop but he can do it on a metafictional level which would definitely work on the tier, pausing the animation.

Bugs in general is just massively too versatile and intelligent for the tier when combined with his plot hax and ability to exist concepts like the Archetypes.

Omniversal Scale Threat:

Outside all space and time, past being and reality is the court of Azathoth.

There exists the formless entities, beings beyond all human comprehension, transcending the archetypes and all concepts humans could possibly recognize, the Outer Gods, whom all reality is formed from. The strongest of the Elder Gods are at the bottom of this tier as Nodens who is usually assumed to be of their kind is mortal enemy of Nyarlathotep. 

Trascending all concepts, normal conceptual manipulation and lower forms of manipulation would do nothing to the formless forms of being of the Outer Gods. Such things as power and speed are transcended by them and are so made irrelevant.

Weakest of their kind is Nyarlathotep, the crawling chaos, known for his sadistic games he plays with the mortal enemies, he is the soul and messanger of the Outer Gods. He is the Black Pharaoh who spreads chaos past even the conceptual plane. 

Most of their kind is unknown even in part by mortals for they are infinite in number just as they are in power. Because of this as well much is not known about many of their members.

Nearing the top of their hierachy if Shub-Niggurath, Ia Ia The Black Goat of a thousand young. Primeval Goddess of Life, Shub-Niggurath spreads her brood, the black young across the multiverse, mutating lesser lifeforms into monsterous forms to aid their survival. She is the hyper concept of life itself, propogating infinitely in mutant form, arguably the spiritual plane itself.

The one who mated with her, potentially the greatest of the Outer Gods is Yog-Sothoth, the Supreme Archetype, from whom all concepts and forms are derived. He is the all knowing source of all being and and all the patterns and forms and concepts of reality. All things that have intelligence are but aspects of Yog-Sothoth, for he is arguably the conceptual plane itself, the source of all concepts and ideas and perspectives and patterns and forms. He knows all for all knowledge is part of him. He is the Gate and the Key, he is the all in one and the one in all, the encompassinging of all reality.

However it is argued whether he is supreme for outside all reality the Court plays infinitely and eternally music. The unspeakable darkness before being and the nameless mist that is the limit to understanding both speak to their shared parent the Lord of All, the nuclear chaos at the center of being, Azathoth, the Blind Idiot God. Azathoth sleeps in the center of creation dreaming of terrible things he can't understand, giving in his dreams each universe it's fragile laws. The court of Azathoth keeps him asleep for if he awakes all things shall be Azathoth again. 

So how to counter that? Well any counter is neccesarily going to need absolute plane hax as any conceptual hax will not affect beings transcendent of concepts, no form can fit the formless entities beyond formed reality. 

Even beyond that, one will face an infinite variety of Outer Gods with each having their own meta-conceptual haxes. 

Some thing Azathoth is strongest being in all of fiction because he transcends so many infinities above so many infinities etc. However with beings transcend over the very concept of infinity and of the concept of power such things seem irrelevant to me.

The biggest way of beating the verse seems to be exploiting the nature of all reality being a part of Azathoth in some sense. This brings me to my first counter

The Law of Identity from Ichiban Ushiro no Daimao

The Law of Identity is a metafictional being that transcends over concepts. She has two notable abilities that would make her incredibly powerful in the Cthulhu Mythos

She is the Law of Identity, the first law of logic that states A=A. As such she has manipulation over that fact and as the Cthulhu Mythos is the dream of Azathoth, would be able to reduce them all to their identities as just Azathoth's dream returning existince to Azathoth as though he had woken up.

She also has an absolute form of plot manipulation which makes her the top of all hierarchies of stories which allows her to transcend any story and view it as fiction. Azathoth the simple dreamer, would be reduced to nothing more then a story from her perspective. The Cthulhu Mythos doesn't seem to have any metafictional hax or hax defense.

It is somewhat ambigious how exactly this would work, so if you don't think it would work, you could use 

 

Lambdadelta from Umineko

Lambdadelta along with her adversary Beatrice had ascended to the higher level of the hierarchy of witches, transcending all concepts and fighting on a high meta level. The Basic attacks of Witches, the Red and Blue Truths are a form of metahax that would likely work on the Cthulhu Mythos. Even the basic magic of Witches are absolute. 

Her basic nature as a Voyager Witch means her being would be protect so long as her metafictional representation can't be argued against properly. For Lambaddelta this is that "hard workers are rewarded" something that the Outer Gods who are used to simply transcending everything else and not being able to fight beings far stronger would not be able to properly understand as it is a rule that does not function in their reality. 

She also has a form of absolute sealing that could even work on Beatrice suggesting she could seal even the Outer Gods. She has a meta regen that works even if she is dissolved into the sea of void beyond all stories and could simply return by thinking though she was formless nothingness. 

That said she is suspectible to losing her magic if she loses faith in herself or is traumatized which could very well happen given her opponents here, similar to what happened to Hypnos. For the perfect counter in my opinion I would suggest

Dream of the Endless from DC Comics

Dream is the Dreaming itself, which contains the collective consciousness which is an infinite hyperstory above all concepts. This is consistent as Dream can exit all creation guarded by the Source Wall when not even a Sixth World being like Perpetua can do, far above the concepts of the Fourth World. Dream is one of the primal aspects making up all of existence, far above conceptual existence.

Dream counters for a very simple reason, in the complete Dream Reality of Azathoth he would be nigh omnipotent. He could solo everyone but Azathoh simply by using his ability to cause a being to wake up from an infinite layer of dreams, meaning they would experience horrible nightmares and wake up infinite times always being alsleep. This would cause Azathoth, the blind idiot god to experience awakening infinite times, always eternally not understanding what he sees as is his character. It would also cause everyone else in the verse to die infinitely.

Dream is canonically in charge of the dreams of the Eldritch Horrors in one aspect who keeps beings like Azathoth asleep. If he was rushed by infinite Outer Gods he can simply summon infinite of himself as he has done. 

Dream of the Endless even has plot manipulation as all stories, including the story he is written on are part of the Dreaming and all stories are dreams, meaning he could control the narrative itself to control the Outer Gods.

Dream of the Endless would be able to reign omnipotent in the Cthulhu Mythos, endlessly controlling the Blind Idiot God.
