** Aesma was the most favoured disciple of YISUN, the creator deity, and possessed enough power to pick up the entire multiverse and wield it like a club. She was also impatient, willfully ignorant, selfish, violent, reckless and brutish, and regularly made absurd decisions like deciding that her ideal husband would be a world-destroying demon. She is the creator of humanity, as a cack-handed rush job because she was jealous of the praise that another divine being was getting.

** ''TabletopGame/WarhammerFantasy'': Morghur the Shadowgave, a HumanoidAbomination that only seems to exist to destroy and despoil all of creation, is completely mindless. His wanderings are almost entirely random as he corrupts all in his path and leaves nothing but ruin and Chaos Spawn in his wake, save that they inevitably lead him, in one way or another, towards Athel Loren.

* ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'' has [[SanitySlippage Kaldor Draigo]]. In the Tabletop lore, this guy is the CanonSue head of the Grey Knights Chapter, performing such insane feats of strength as banishing ''[[PersonOfMassDestruction Mortarion]]'' pretty much by himself and '''carving his predecessor's name into the guy's heart while he did so''', surviving on his own, completely unaided '''in The Warp itself''' for extended periods of time. TTS has decided to have some fun with this: while Draigo is ''even more powerful'' than he is in the lore, being capable of punching out Daemon Primarchs in OneWingedAngel mode in less than a second, slaughtering hordes of daemons effortlessly, cloning himself and ''eating a star'', this is because he's so ''utterly insane'' that he just can't comprehend that he may ever lose or there's any limit to his abilities. As a result of The Warp suffusing him so thoroughly and it running on ClapYourHandsIfYouBelieve, there really ''isn't'' any limit to Draigo's capabilities any more...at the cost of him being a hilariously incoherent wreck who goes off on tangents and barely seems to recognise what's going on half the time. It's ''very'' telling that when [[spoiler:Leman Russ]] indirectly asks [[spoiler:the stranded Karamazov]] if he'd even call Draigo a "sentient being", ''Draigo himself'' pipes up to yell "NOOO!!" in reply.

* A RunningGag in ''WebAnimation/ZeroPunctuation'' is that characters whose quests are suposedly divinely inspired are actually madmen who hallucinated a giant, floating ocleot head who screamed at them to "Kill the Whores!" However, when the actual, capital-G God shows up, he's depicted as the classic GrandpaGod, but it sure is strange that so many people have the same hallucination...

* ''WesternAnimation/AtlantisTheLostEmpire'': It's implied that Rouke's crystal transformation has subsumed what's left of his rationale. All the formerly crafty and cunning commander can do now is howl and snarl like an animal, and he lunges blindly into the propeller blades trying to get Milo. The novelization mentions that Rourke seems to be in "a trance, as if he did not see or feel the world around him."

* ''Manga/{{Berserk}}'': When Emperor Ganishka attempts the forbidden ritual of giving himself a second reincarnation in order to gain the power to defeat Griffith, he ends up turning into a many-tentacled monstrosity which towers over the whole city of Wyndham. As Ganishka first emerges he's still himself mentally--albeit DrunkOnTheDarkSide--but by the time he reaches full height the transformation is already causing his ego to implode. He mistakes his own soldiers below him for tiny insects and starts on stepping them, thinking the "[[LudicrousGibs red flowers]]" that bloom when he crushes them are beautiful. A minute later he can't even remember who he is anymore, and does not comprehend the destruction he's causing by trampling and raining fire on everything in his path.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': King Sombra in his shadow form, while very huge, powerful, fluid, and able to spread with only a single fragment of his horn, is only capable of speaking small sentences and phrases and charging forward, in contrast to the highly-prepared sorcerer he once was. Though that could be because of the thousand years he spent [[AndIMustScream trapped in ice]]. ''ComicBook/MyLittlePonyFiendshipIsMagic'' heavily implies it's actually due to him becoming far stronger during said banishment, but HulkingOut in the process.

** Meanwhile ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'' gives us two examples; the first being [[spoiler: Zelda herself, who, after traveling thousands of years back in time, swallows a divine stone that transforms her into a powerful and immortal light dragon that lives into the current age, but at the cost of her [[DeathOfPersonality sanity and intelligence]], rendering her into little more than a mindless beast wandering aimlessly high in the skies of Hyrule. Then, in the game's climax, when a revived Ganondorf is backed into a corner and realizes that there's a very real chance of him being defeated by Link, he [[VillainousBreakdown absolutely loses his shit]] and undergoes the same dragonification process, thus becoming an equally powerful and mindless ''dark'' dragon.]]

* ''VideoGame/EldenRing'': The Prince of Death, creator of Those Who Live In Death and source of Deathblight, has godly power but isn't so much a god as a cancer on the Erdtree, corrupting it with influence that simply spreads without direction or purpose.[[spoiler: The Prince of Death ''was'' a demigod; Godwyn the Golden. But when the Black Knives killed his soul and his technically-living but braindead body was buried under the Erdtree, it mutated into the Prince of Death and polluted the Erdtree with itself and its curse of unnatural half-death. It bears little resemblance to Godwyn's original self and is, for all intents and purposes, an object that happens to be theologically radioactive.]]

* ''Manga/BlackClover'': Demons (not [[TheLegionsOfHell devils]]) are born when someone is corrupted by negative mana from the Underworld. The result is anything but pretty: they become towering, [[MultiArmedAndDangerous multi-armed]] giants with immense magic power, driven entirely by instinct. [[PersonOfMassDestruction A demon is easily powerful enough to raze an entire country]], and the transformation irreversibly alters their soul. They cannot be reasoned with, either; the only way to stop them is to seal them or outright kill them.

* In one ''ComicBook/DoctorStrange'' arc, Strange destroyed a primordial entity of Chaos by assuming its power--and then killing himself. This led to him briefly becoming an all-powerful transcendent being with no ego or identity. Ironically, it was one of Strange's old enemies who dragged him back into the "illusion" of self.
* Larfleeze from ''Franchise/GreenLantern'' is a deranged IdiotSavant whose only concern is [[StickyFingers stealing shiny things]]. He's also the only Orange Lantern, meaning he has sole access to ''all'' of the Orange Light's power. This makes him one of the most powerful ring wielders in the universe, a borderline PhysicalGod in comparison to TheChosenMany that compromise the other Lantern Corps. Fortunately for everyone else, his insanity and kleptomania means that he prefers to hide himself away and guard his loot rather than cause havoc.
* The One-Below-All from ''ComicBook/ImmortalHulk'' is a terrifyingly powerful EldritchAbomination, but it gradually turns out that it has no real mind of its own. It has a drive and desire ([[OmnicidalManiac destroying reality]]), but cannot actually focus or think to achieve that goal without [[MouthOfSauron a mortal host]] to direct it. As Brian Banner puts it, the thing is all id and no ego.
* In the ''ComicBook/{{Preacher}}'' comic series, Jesse Custer was the host for Genesis, a potentially all-powerful newborn spirit that had no sense of individual will. It's repeatedly likened to a supernatural battery.
* Thunderwing from IDW’s ''ComicBook/TheTransformersMegaseries'' used [[ProfessorGuineaPig himself]] as a test subject for his experiments with Pretender technology. These experiments made him extremely powerful and nearly indestructible, but also drove him mad, and the formerly brilliant scientist is now a near-mindless PersonOfMassDestruction.
%%* Could describe Dr Manhattan from ''ComicBook/{{Watchmen}}''. His godlike power and nonlinear perspective lead to an increasing detachment from humanity and a complete lack of motivation to make any choices or really ''do'' anything. He's a nearly omnipotent being who spends most of the plot of the book just sitting around on Mars because he can see all of time and doesn't care about any of it since he knows its all predetermined. He seems to have grown past this by the end of the book, finding some motivation by actually being surprised by events again.

* ''Franchise/WonderWoman'' [[ComicBook/WonderWoman1987 Vol 2]]: As Zeus' powers degrade (due to [[GodsNeedPrayerBadly lack of worshipers]] and being unable to adapt to drawing power from concepts like Ares and Aphrodite) his mind starts slipping. He starts having dementia-like symptoms and he's unable to keep his different aspects contained, as a crazed Jove at one point takes over and claims Zeus is dead. His reaction is to double down on all of his worst qualities in a desperate bid to keep from fading out entirely.

** According to ''Literature/HyruleHistoria'', Ganon never fully recovered from his botched resurrection in ''VideoGame/TheLegendOfZeldaOracleGames''; his next appearance in ''VideoGame/TheLegendOfZeldaI'' is described as a beast deprived of Ganondorf's genius intellect, explaining why the final battle of that game is more of a simple KingKoopaCopy boss fight in relative comparison to other games.
