16	->'''''"POWERRRRRRRR! UNLIMITED POWERRRRRRRR!"'''''
17	-->-- '''[[Characters/StarWarsEmperorPalpatine Darth Sidious]]''', ''Franchise/StarWars: Episode III — Film/RevengeOfTheSith''
18
19	Villains aren't ones to preach self-control or restraint. They might understand and even use it to good effect, but in their blackest hearts they want to [[LargeHam live it up]] and [[ChewingTheScenery tear up the scenery]]... in this trope's case, ''literally''.
20
21	A villain who is Drunk on the Dark Side will show how "EvilFeelsGood", [[AGodAmI he has become a God]] and WithGreatPowerComesGreatInsanity, releasing waves or [[AgonyBeam bolts]] of dark power, or if they're powerful enough cause a deliberate "controlled" SuperPowerMeltdown that can become a SphereOfDestruction.
22
23	The [[SanityHasAdvantages downside to this exercise in expressive megalomania]] is that it's equivalent to (and sometimes paired with) becoming a OneWingedAngel, meaning the villain has completely surrendered to TheCorruption and is [[MoralEventHorizon too far gone]] for the heroes to be able to [[SaveTheVillain save]], and thus [[ThouShaltNotKill killing]] the villain becomes [[WhatMeasureIsANonHuman acceptable]].
24
25	Compare DrunkWithPower, when it's authority-based power that goes to one's head. See also EvilIsHammy, in which simply being evil is what causes scenery-chewing, rather than being evil and powerful.
26
27	Contrast ThisIsYourBrainOnEvil, where the villain's mental processes are equally affected, but not in a fun way. The drug metaphor sometimes breaks down here, as villains will start out experiencing ThisIsYourBrainOnEvil, then proceed to become Drunk on the Dark Side when their humanity degrades to the point that they stop fighting it. (With drugs, you normally lead off with the carefree intoxication part, while the soul-crushing addiction part comes later.)

31	!!Examples:
32	[[foldercontrol]]
33
34	[[folder:Anime & Manga]]
35	* In ''Manga/{{Bleach}}'', [[spoiler:Tosen]] goes ''absolutely insane'' after he realizes [[spoiler:his [[BecomeYourWeapon Resurreccion]] gives [[BlindWeaponmaster him]] eyesight]]. More than he already was, anyway.
36	** And [[spoiler:Aizen]] has gone off the deep end as well, doing incredibly dickish things for no reason except that he can, and loses it not once, but twice, [[spoiler:when Gin succeeds in killing him and when he discovers Ichigo's more powerful than him now.]] Yes, that's in the correct order.
37	** Mabashi, in the Bount arc, was so against sucking living souls that he actually had to be ''force-fed'' his first. Afterward he goes AxCrazy, [[MoralEventHorizon burning through any sympathy we might have had]] ''very'' quickly.
38	** Kariya, the Bount leader, attacked his allies in Soul Society and had to be restrained by two of his followers.
39	* Nene in ''Anime/BlueDragon'' does this when he absorbs the main characters' powers.
40	* ''Anime/CardfightVanguard'': [[spoiler:Aichi Sendou]] goes from ShrinkingViolet, [[ShyBlueHairedGirl Shy Blue Haired Guy]] protagonist to a (possibly) mentally unstable kid desperate to be acknowledged as strong once he's hooked on [[PsychicPowers Psyqualia]]. So much so that he abandons the very card that means the world to him in favour of the clan's EvilCounterpart. He manages to get over it, but once he faces [[BigBad Ren]], whose pretty much the same, Psyqualia takes hold again and even develops his own EvilLaugh.
41	* Muska in Miyazaki's ''Anime/CastleInTheSky'' qualifies at the climactic events of the film [[spoiler:when he takes control of Laputa's powers and both kills the general and his soldiers and destroys the army's battleship with an army of robots, gloating, "A superior being such as myself has only one option—''burn them''!"]]
42	* ''Manga/DeathNote'': Light Yagami started out as a kid groomed for success. His dream was to join the police and assist his father, the Chief of Police. He then became the popular guy in high-school because he was smart, studious, and {{Bishonen}}. He was even smart enough to be one of the top scoring high-school students in all of Japan! ''[[OhCrap Then he found a Death Note...]]''
43	* Fused Zamasu in ''Anime/DragonBallSuper''. While he was definitely a bit off his rocker even before [[spoiler: Future Zamasu and Goku Black fused]], in this form he ditches the ColdHam of his previous forms for pure scenery-chewing melodrama, and completely discards their [[NoNonsenseNemesis pragmatism]] in favor of massive, flashy attacks and feeding his god complex. [[spoiler: As Infinite Zamasu, it's even worse, to the point where he's essentially an AlmightyIdiot.]]
44	* In ''Manga/JoJosBizarreAdventure'', villains have a habit of going on a power trip just minutes before they're defeated.
45	** In ''Battle Tendency'', Kars finally succeeds with his aspiration of becoming the UltimateLifeForm and goes on a [[ThePowerOfTheSun Hamon]]-fueled rampage that's so extreme that he triggers an immense volcanic eruption that flings him out into space where none of his powers are able to save him and [[AndIMustScream his immortality dooms him to drift through the empty void until the day he stops thinking.]]
46	** In ''Stardust Crusaders'', DIO first stalls for time until the sun has set so the Joestars cannot exploit his [[OurVampiresAreDifferent vampiric]] weakness to sunlight. Then, after a CarChase [[ItAmusedMe for shits and giggles]], he becomes a NoNonsenseNemesis, mercilessly killing [[WeakButSkilled Kakyoin]] by punching a hole straight through him and leaving [[GuileHero Joseph]] on the brink of death with a knife through his neck. When he realizes that [[TheHero Jotaro]] has the same TimeStandsStill powers as him, he ditches the straight-forward No-Nonsense stuff. And then... he drains Joseph's blood... and becomes so high on his newfound powers that he might as well have drained the VillainBall...
47	** In ''Diamond is Unbreakable'', Yoshikage Kira actually succeeds in killing off all of the heroes with his newfound unstoppable ability [[GroundhogDayLoop Killer Queen Bites the Dust]]. However, in his moment of victory, Kira gloats about his victory and identity out loud right before the heroes are fated to die, alerting Josuke to his vicinity and forcing him to release Bite the Dust and rely on his original Stand powers.
48	** By the end of ''Stone Ocean'', Father Enrico Pucci slaughters all of the protagonists save Emporio, a young boy, and wipes them from existence to finally complete DIO's ultimate plan. By the time he confronts Emporio, he believes that he's completely won and there is nothing that can be done against him. This allows Emporio into tricking Pucci into inserting the Weather Report Stand Disc into his body and allows him to finally kill him.
49	** During the penultimate battle of ''Steel Ball Run'', President Valentine believes himself to be complete invincible with his new D 4 C Love Train ability, and declares that he will use this power to redirect all misfortune for the United States onto foreign countries. This overconfidence allows Johnny to throw him off guard when manages to acquire a power that surpasses Love Train.
50	* ''Anime/MagicalProjectS'': When Misao, normally a shy, timid girl, transforms into her [[DarkMagicalGirl evil magical self]], she starts to do everything she couldn't in powerless form -- and as Pixy Misa, she starts to sing about how powerful she is (she sings in the middle of the street, as everyone assumes a WTF expression) [[HilarityEnsues with hilarious results]].
51	* Sasuke Uchiha from ''Manga/{{Naruto}}'' initially wants power to surpass his treacherous brother [[AloofBigBrother Itachi]], but with time, he spirals dangerously out of control. Too much exposure to evil and MindRape twisted him into an AxCrazy lunatic -- learning Itachi [[spoiler:pretended to be a villain so his brother would kill him to atone for slaying his clan, but actually still loved him]] was what made him crack. Now, he's to the point where he wants his whole village wiped out. Unless... his [[spoiler:revived brother can convince him otherwise]]...
52	** Turns out [[spoiler:it just made him more convinced to destroy the village]].
53	*** But after [[spoiler:having spoken with all four Reanimated Hokage brought back by [[BackFromTheDead Orochimaru]], he's gone to [[HeelFaceTurn help the Shinobi Alliance]] in the war, and even expressed a desire to become Hokage himself to stop the ninja system that ruined Itachi's life. [[HeelFaceRevolvingDoor What]]]].
54	*** And then it turns out that what he ''meant'' when he said that was that he was going to [[spoiler:pull a ZeroApprovalGambit and get the ninja world to unite against him. He seals away the Tailed Beasts and the climactic fight of the series is Naruto beating some sense into him]].
55	* During the Paramount War in ''Manga/OnePiece'', Blackbeard [[spoiler:stole the Tremor-Tremor Fruit from Whitebeard's body]] and goes absolutely ''apeshit''. He immediately challenges every marine present to a fight, and then threatens to destroy the island of Marineford, after that he starts ranting about he'll kill everyone and devour them with his other power, the Dark-Dark Fruit, laughing the whole time. [[spoiler:It takes the arrival of Shanks to sober him, but it's likely a temporary solution for now at that]].
56	* In ''Roleplay/RecordOfLodossWar'', the evil magician Wagnard becomes even ''more'' megalomaniacal by the final episode, cackling with mad glee as he blasts at Parn and Ashram with his magic from his scepter [[spoiler:until Ashram eventually kills him. Even so, he gets to have one last bit of scenery to chew on as he screams, "All Lodoss is doomed! Hahahahaha! Nothing will remain! NOTHING! Hahahahahahaha!"]]
57	** Note that this is a failure in adaptation. In the original novel his plans are much more thought out and getting killed is actually the last part of his plan, so he can be reborn into a lich. Performing the ritual to resurrect the demon god AND people stopping the ritual in the midst of it so the demon god does NOT get resurrected are both well written in his plans. This is understandable because when the anime was made, the novel was still not finished and the animators only had an outline to work with and there were way more characters involved in the novel that the shorter anime could not implement. (Which made way to the sequel anime instead).
58	* [[spoiler:Seidou Takizawa]] has become that in the sequel/second part of ''Manga/TokyoGhoul''. He's enjoying being so powerful, giving philosophical speeches to his captive audiences, cackling like a lunatic, taunting his prey with sing-songing nonsense, and is thrilled when the sound system gets activated — meaning everyone can hear him gloat! Moderation and restraint do not seem to be in his vocabulary anymore.
59	[[/folder]]
60
61	[[folder:Comic Books]]
62	* ''ComicBook/{{Batgirl}}'': In the storyline ''ComicBook/TheAttackOfTheAnnihilator'', a resentful scientist called Kenneth Anderson runs a test on an alien rock and is exposed to odd energies which transfom him into some kind of psychic mutant. Immediately Anderson changes his name to "Annihilator" and starts ranting about being becoming an angry, punishing god as floating around and blasting buildings.
63	* ''ComicBook/{{Shazam}}'': ComicBook/MaryMarvel in ''ComicBook/CountdownToFinalCrisis''. So much so she goes evil ''twice''.
64	* ''ComicBook/GreenLantern'': The page image is Hal Jordan in ''ComicBook/EmeraldTwilight'', where he finally snaps due to being possessed by Parallax and goes on a rampage murdering other lanterns for their rings.
65	* ''ComicBook/MegaManArchieComics'': Happens when Mega Man starts getting the Robot Masters' powers he starts to get increasingly cocky and arrogant, to the point where he declares himself invincible. This results in Dr. Light having to contain him while he throws what amounts to a super-powered temper tantrum. When he calms down, he's so horrified at his response that he asks Dr. Light [[BagOfSpilling to take them away]].
66	** An act of FridgeBrilliance on the writer's part - this explains why Mega Man's acquired powers don't carry over into the next game - he's only borrowing them until Wily's beaten.
67	* ''ComicBook/ScarletWitch'': The Scarlet Witch in ''ComicBook/AvengersDisassembled'' and ''ComicBook/HouseOfM''. As of ''ComicBook/AvengersTheChildrensCrusade'', she's fine again.
68	* ''ComicBook/{{Superman}}'':
69	** Every time ComicBook/LexLuthor gains superpowers, he quickly lets them go to his head. His term as president came to an end in ''Public Enemies'' when he went crazy after doping himself with Venom and liquid Kryptonite before going on a rampage in an Apokoliptian battle suit.
70	** In ''ComicBook/FiftyTwo'', [[spoiler:he uses his own Exo-gene therapy to copy Superman's power set]] and spends most of the time reveling in his new powers.
71	** After temporarily wielding an Orange power ring in ''ComicBook/BlackestNight'', Luthor spends most of his story in ''ComicBook/TheBlackRing'' trying to replace it with something equally or more powerful.
72	** ''ComicBook/TwoForTheDeathOfOne'': [[EvilSorcerer Syrene]] starts absorbing the Runestone o Merlin's magic and ascending to a higher plane of existence, and she completely delights in the feeling of godlike power.
73	--->'''Syrene:''' "The power insinuates my body. And it feels so very, very good. I see things, Satanis, things I've never imagined. Worlds and planes... levels within levels... realities so far beyond any ever seen by man. I see myself a goddess over planets not yet born. It is wonderful, Satanis... inspiring... and almost impossible! All that can be is within my very grasp! All ready to be taken. All ready to be plucked!"
74	** ComicBook/SuperboyPrime, starting with ''ComicBook/InfiniteCrisis'' and getting steadily worse thereafter.
75	*** In ''ComicBook/SinestroCorpsWar'' Prime seemed like he had matured a great deal and was much calmer...this was a ruse. Once he was back on Earth and fully juiced up by the rising sun he ''immediately'' betrays Sinestro and declares that he'll fight '''everyone''', both corps and all the assorted superheroes caught in the middle. [[BloodKnight Prime carves through innumerable aliens with a genuine smile on his face.]]
76	* ''ComicBook/{{The Transformers\|Marvel}}'': In the original comic book series, this happens to [[TheStarscream Starscream]] after he absorbs power from a mysterious satellite called the Underbase and becomes so strong that he's able to take on the combined might of both the Autobots and Decepticons combined and [[CurbStompBattle curbstomp them both]]. He's only defeated when Optimus Prime tricks him into absorbing the rest of the Underbase's power, which turns out to be [[ExplosiveOverclocking far too much]] for any single Transformer to hold.
77	* ''ComicBook/WonderWoman'' [[ComicBook/WonderWoman1987 Vol. 2]]: The White Magician is just so giddy about his new body and increased magical power that he brushes off Circe saying his magic is twisted and going to tear his body apart. He's in denial even as his magic kills him and leaves only a pile of ashes for his remains.
78	* ''ComicBook/XMen'':
79	** [[Characters/MarvelComicsMagneto Magneto]] tends to become pretty hammy and nuts whenever he goes full throttle with his powers. Then again, he commands absolute power over one of the four fundamental forces of the universe, took out entire Avengers teams (including the likes of ''Hercules and Thor''), and for a while in the early 90s was ''officially'' the most powerful character on Earth. That kind of power would give just about anyone a rush. It's also been implied that his magnetism powers make him ''[[{{Pun}} literally bipolar]]''.
80	** [[Characters/MarvelComicsMadelynePryor Madelyne Pryor]] did this when she became the Goblyn Queen and tried to [[OffingTheOffspring sacrifice her own son]] to usher in a Hell on Earth.
81	[[/folder]]
82
83	[[folder:Fan Works]]
84	* ''Fanfic/{{Amenaza}}'' has Naruto become a FallenHero and [[BecameTheirOwnAntithesis twisted shadow of his former self]] as a Hollow, intent upon using his powers however he sees fit, not caring -- or worse, outright ''delighting'' in all the pain he's causing.
85	* In ''Manga/AtChirei'', Okuu remarks about how ''good'' it feels to fire off her ArmCannon, hinting at how she'll eventually grow [[WithGreatPowerComesGreatInsanity obsessed with her own power]].
86	* The ''Franchise/MarvelCinematicUniverse'' fic ''Fanfic/BecauseIKnewYou'' places emphasis on how contact with the Darkhold was corrupting Wanda Maximoff to drive her to hunt for her children across the multiverse; it takes learning the reason for the memory spell to erase all knowledge of Peter Parker (Wanda deflected the spell in the believe that it was a deliberate attack on her) to give Wanda the necessary emotional kick to throw off the Darkhold's influence, as she left the book behind while visiting New York as a part of her still recognising that the book was too dangerous to be brought back to civilization.
87	* ''Fanfic/TheCelestiaCode'': In order to save her friends from the dark crystal [[spoiler:upon its shattering]], Twilight Sparkle absorbs all of the unleashed magic. This sends her on a power trip as she tries to use this magical might to impose order upon the changelings. [[spoiler:Cshareee snaps her out of it with a GoThroughMe moment, and Twilight disposes of the excess magic by blasting the uninhabited desert.]]
88	* ''Fanfic/ChaosTheory'': The Shadow provides near-unlimited prana to the Servants it corrupts, offering them one ''hell'' of a power trip. Not even [[spoiler:Saber herself]] is able to resist its lure.
89	* ''Fanfic/ChildOfTheStorm'' has several examples:
90	** More generally, it goes with the ''Literature/DresdenFiles'' depiction of BlackMagic and its effects - the more you twist magic into black magic, the more it twists you back, making it easier to use and you more twisted at the same time. It is directly paralleled with drug addiction on at least one occasion in the sequel, and it's made clear that it can transform even the best of people into a monster. While this mostly applies to Wandless magic because Wanded wizards have their wands as a buffer to avoid/delay incipient insanity, it's pointed out that if you're using BlackMagic regularly, you're unlikely to be sane anyway no matter how you're doing it. There are ways to handle it safely, but it's extremely difficult, noted as the final test of an Apprentice to the Sorcerer Supreme - for starters, some of the worst Dark Lords and Ladies in history have been Apprentices who failed...
91	** Gravemoss, already an insane OmnicidalManiac and part of the BigBadEnsemble of the first book, gets even worse under the influence of the Darkhold - which offers power and knowledge at the cost of falling under the influence/suffering eventual DemonicPossession by its author, the Elder God of Chaos and BlackMagic, Chthon. His struggles to maintain control and not give in are directly comparable to a recovering addict trying to avoid relapsing - and Strange's strategy in the final battle of book one includes jumping up and down on his various buttons to force him to give in. It would be quite tragic if he didn't [[AssholeVictim absolutely deserve it]].
92	** Any and all manifestations of the Dark Phoenix tend to vary between ColdHam and ChewingTheScenery.
93	** Reynolds [[spoiler:a.k.a. the Void]] revels in his addiction, zig-zagging between this and ThisIsYourBrainOnEvil. He ''knows'' he's an addicted PowerParasite, he just doesn't ''care''.
94	* ''Fanfic/JauneArcLordOfHunger'': Whenever Nora absorbs any of Jaune's Force Lightning, she transforms into an ultraviolent LargeHam who cackles maniacally while wailing on her opponents.
95	* ''Fanfic/AMothToAFlame'': Marcy tumbles headlong into this, especially after GainingTheWillToKill thanks to The Core's final test, as she goes LaughingMad and accepts The Core's offer to [[spoiler:join their MindHive]] with TearsOfJoy in her eyes.
96	* In ''Fanfic/TheShatteringOfOz'', the Nome King attempts to use an elaborate ritual to harness the power of the Ruby Slippers by turning himself into a human, but his behaviour becomes increasingly erratic and reckless as the scale of their magic starts to twist his mind out of shape. Elphaba refers to this as "Thaumaturgical Psychosis", with his mind unable to properly channel the scale of their power. By the time of the final clash, [[spoiler:Dorothy is able to take the Slippers and use them to undo some of the damage to Oz without any ill-effects, which Elphaba speculates is because the Nome King's efforts had drained off some of the Slippers' excess power, allowing Dorothy to tap enough energy to heal Oz without repairing all the damage or leaving her mentally scarred]].
97	* In the ''Series/Charmed1998'' fic ''[[https://www.fanfiction.net/s/6250877/1/Tempus-Fugit Tempus Fugit]]'', after circumstances force Phoebe to temporarily swap powers with Cole, she becomes increasingly hostile as she spends more time with his abilities. When she goes so far as to attack Paige for 'replacing' her, Prue, Piper and Paige are forced to temporarily strip Phoebe of her powers to give her the chance to get back to herself.
98	* ''WebVideo/TouhouTheIronOfYinAndYang'': This is a natural side-effect of coming into contact with a [[SevenDeadlySins Gluttony Shard]]: it turns whomever taps into its power into TheUnfettered. Which is a ''major'' issue in a place in Gensokyo, which is effectively held together by its residents recognizing the importance of HoldingBackThePhlebotinum and ''not'' going all out.
99	* ''Fanfic/WingsOfRebellion'': Crow attests that gaining his persona made him feel like he could accomplish ''anything'' he wanted. So when the entity that granted him that power informed him about his father, he eagerly leapt at the chance to take revenge.
100	[[/folder]]
101
102	[[folder:Films — Animated]]
103	* In Disney's ''WesternAnimation/{{Aladdin}}'', Jafar really hams it up after wishing to become the world's most powerful sorcerer and in his LaughingMad moment after the Prince Ali Reprise, and when even that isn't enough, [[spoiler:he wishes to become a genie himself and hams it up even more until he notices the BIG downside to being a genie]].
104	-->'''Genie:''' [[LargeHam PHENOMENAL COSMIC POWERS!]] [[ClippedWingAngel Itty bitty living space]].
105	* ''WesternAnimation/Frozen2013'' has an unusual example with AntiVillain Elsa when she realizes she can finally express her emotions in "Let It Go", below, boy does she ever rise to the occasion. It's unusual, though, in that it was originally meant to be a VillainSong along these lines, but after actually listening to it, the writers pivoted to make Elsa sympathetic, characterising it more as her finally cutting loose, relieved that she can finally do so without having to worry about hurting anyone. Yeah... didn't work that way.
106	* ''WesternAnimation/MyLittlePonyEquestriaGirls'':
107	** Sunset takes a few levels in psycho and [[EvilIsHammy hamminess]] when she finally gets the crown and is transformed by its magic. Prior to it, she was nasty but had some [[EvenEvilHasStandards standards]] and operated on a more rational level. She confirms in [[WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames Friendship Games]] that the power of the crown was so great that it overwhelmed her. [[spoiler:The climactic fight with Midnight Sparkle has her able to control the magic she's using that time around, instead of this happening.]]
108	** This is pretty common in ''MLP G4'' overall. Princess Luna also ramps up her (already considerable) hamminess as Nightmare Moon, and Midnight Sparkle takes a shy, awkward girl and turns her into someone who could give Darth Sidious a run for his money.
109	* ''WesternAnimation/ThePagemaster'':
110	-->'''Fantasy:''' Dr. Jekyll? Dr. J?\
111	'''Mr. Hyde:''' [[LargeHam My name is MR. HYYYYYYDE!]]
112	[[/folder]]
113
114	[[folder:Films — Live-Action]]
115	* ''Film/TheCovenant'': Chase spent his teen years abusing his powers, to the extent that he doesn't care about anyone else so long as he gets more power.
116	* ''Film/DungeonsAndDragons2000''. Jeremy Irons hams it up as Profion at the climax so much, his skull is ready to pop out of his head.
117	-->'''Profion''': '''LET THEIR BLOOD RAIN FROM THE SKYYYYYY!!!!'''
118	* ''Franchise/{{Hellraiser}}'':
119	** In ''Film/HellboundHellraiserII'', [[spoiler:Dr. Channard]], after becoming a Cenobite, joins their revelry of pain.
120	** In ''Film/HellraiserIIIHellOnEarth'', the turned Cenobites (the ones who can still talk, at any rate) are all jubilant about becoming Pinhead's minions so they can cause destruction and kill people.
121	* Galadriel in the ''Film/TheLordOfTheRingsTheFellowshipOfTheRing''. [-"[[https://www.youtube.com/watch?v=K3VOf3CBGvw In place]] of a [[EvilOverlord Dark Lord]], '''''[[GodSaveUsFromTheQueen YOU WOULD HAVE A QUEEN!]]''''' Not dark, but [[LightIsNotGood beautiful and terrible as the dawn]]! Treacherous as the sea! Stronger than the foundations of the earth! '''''[[VoiceOfTheLegion ALL SHALL LOVE ME AND DESPAIR!]]"'''''-] Slight subversion since she's testing herself against what she might become under the Ring's [[TheCorruption corruption]]. (It's much more subtle in the book.)
122	* Skeletor pulls one of these in the ''Film/MastersOfTheUniverse'' movie. Oddly enough, his godlike power does not allow him to win a swordfight against He-Man.
123	-->[[PunctuatedForEmphasis "Now... You. Will.]] [[KneelBeforeZod KNEEL!!"]]
124	** Is it any wonder this is [[Creator/FrankLangella the actor's]] favorite role?
125	* ''Franchise/MarvelCinematicUniverse'':
126	** In ''Film/IronMan1'' [[spoiler:Obadiah Stane]], normally calm and AffablyEvil, seems to lose his shit after becoming the Iron Monger, and even seems to [[LampshadeHanging realize it]].
127	-->'''[[spoiler:Stane:]]''' I have to admit, [[PowerHigh I'm deeply enjoying the suit]]!
128	** Various parties have interpreted this as the reason for [[spoiler:Wanda Maximoff's]] actions in ''Film/DoctorStrangeInTheMultiverseOfMadness'', speculating that [[spoiler:her trauma from losing her children and her attempts to use the Darkhold to find them drove her insane, giving her the power to explore the multiverse but corrupting her so that she would kill the heroes of an alternate Earth and plans to steal the powers of an innocent child even knowing that this will kill the girl]].
129	* [[spoiler:Theodora]] dives into this trope headfirst in ''Film/OzTheGreatAndPowerful'', so deeply that she even scares Evanora, who'd convinced her to become a WickedWitch in the first place.
130	* In ''Franchise/StarWars'', this is part and parcel of a [[ReligionOfEvil Sith]]'s power in the first place -- as opposed to the [[WarriorMonk Jedi, who control the Force through serenity and self-discipline]], a Sith unleashes it through [[ThePowerOfHate raw, destructive emotion]] -- and as such, even a normally self-controlled Sith like TheEmperor will go straight to LargeHam mode when using his powers as we see in ''Film/RevengeOfTheSith'' & ''Film/ReturnOfTheJedi''. Add to this the chronic [[ProperlyParanoid justified paranoia]] about everyone around you due to their ChronicBackstabbingDisorder and KlingonPromotion as standard operating procedure. This also explains a lot as to why almost ''every'' Sith in the ExpandedUniverse acts (and [[EvilMakesYouUgly looks]]) like they [[ThisIsYourBrainOnEvil snorted a mountain of cocaine]] (or, in-universe, [[FantasticDrug spice]]).
131	* ''Film/XMenFilmSeries''
132	** ''Film/TheWolverine'': When Ichirō starts to [[spoiler:age back through sucking Wolverine's powers, he laughs like a lunatic]].
133	** ''Film/XMenApocalypse'': Professor X enters a deep trance when [[spoiler:Apocalypse possesses his mind through Cerebro]]. Xavier is so overwhelmed and mesmerized by the plethora of god-like abilities that he comes into direct contact with ("I've never felt power like this before") that he initially doesn't resist the invasion, and he's temporarily corrupted by it (hence his BlackEyesOfEvil). It's only when Hank tries to remove the Cerebro helmet that Charles snaps out of the daze (which results in him regaining his normal eye colour) and attempts to fight off his attacker. While under [[spoiler:Apocalypse's control]], Professor X is in a calm state (the drug-like high), but the moment he struggles to break free, he's constantly ''screaming'' in agony (the withdrawal)--EvilFeelsGood, in other words, even for an AllLovingHero like Xavier.
134	[[/folder]]
135
136	[[folder:Let's Play]]
137	* Most LetsPlay videos of ''VideoGame/GarrysMod Murder'' involve this to an extent, although most of these examples [[PlayedForLaughs are not taken entirely seriously]]. Many examples below:
138	** From LetsPlay/HatFilms, Ross Hornby will pull out the knife with no warning, shouting [[MemeticMutation EAT SHIT! EAT SHIT!]] or some amusing variation thereupon at the top of his lungs. His two co-stars do this on occasion, but Ross is by far more noticeable.
139	** LetsPlay/{{Turpster}} is considerably better than Ross at hiding that he is the murderer, but upon being discovered he puts on a creepy voice and gives a brilliant EvilLaugh.
140	** LetsPlay/LewisBrindley and LetsPlay/SimonLane rarely delve into this, but when they opt to, they can be very hammy, funny and terrifying all at once. The former [[http://goodurlsalltaken.tumblr.com/post/91952356702/lewis-d-you-fucking-muppet-cmere-source goes on a gangster-style rampage]] (audio file NSFW with lots of swearing and profanity), complete with a ''Series/EastEnders'' impression. The latter learns not to do it after his first attempt at doing so [[DeconstructedTrope gives him away and gets him killed]], but later does it for comedy, at one point going on a hammy rampage which can be heard [[http://goodurlsalltaken.tumblr.com/post/91952168247/g-mod-murderer-simon-source here]] (also very NSFW due to constant [[ClusterFBomb swearing]], and you would be advised to turn your volume down).
141	* LetsPlay/{{Strippin}} is normally composed enough, albeit slightly boisterous, but during [[https://www.youtube.com/watch?v=vLmCfat9Ba0&list=UUWiPkogV65gqqNkwqci4yZA a playthrough]] of ''Damned'' with LetsPlay/InTheLittleWood, LetsPlay/{{Rythian}} and LetsPlay/ZoeyProasheck, he shows he's NotSoAboveItAll, with CreepyChild impersonations and sadistically toying with the others.
142	* During series 2 of the ''LetsPlay/{{Yogscast}}'' playthrough of ''VideoGame/TroubleInTerroristTown'', the guys are mostly savvy enough to avert this, but in the final episode, LetsPlay/LewisBrindley embraces this trope. After [[https://www.youtube.com/watch?v=aeoGFYELr-Y#t=533 a small firefight]] which results in the deaths of LetsPlay/{{Sips}} and LetsPlay/{{Sjin}}, Lewis initially tries to deny that he is responsible for their deaths, but upon further probing he hammily confesses, then guns down Ross and Trott, ranting about [[InsaneTrollLogic how he had to kill]] and boasting as he does so. Sjin puts it down to DemonicPossession.
143	-->'''LetsPlay/SimonLane:''' What the fuck is going on?\
144	'''Lewis:''' '''Die, all of you! EAT SHIT! EAT SHIT!''' I'm possessed!\
145	'''Sjin:''' ''(helplessly laughing)'' Ross has somehow possessed Lewis!

148	[[folder:Literature]]
149	* ''Literature/AnnalsOfTheWesternShore'': In ''Gifts'', the Caspro family legend of Blind Caddard ends this way. Although he learned to control his power, in his old age he starts unmaking anything and everything that pisses him off even slightly. He eventually has a HeelRealization and uses a mirror to unmake his own eyes.
150	* ''Literature/DreambloodDuology'': Because dreamblood is highly addictive, once a Gatherer kills on purpose and without being welcomed, he becomes a [[OurVampiresAreDifferent Reaper]] and requieres a constant supply of dreamblood. And he will kill anyone who comes close enough to get it.
151	* In ''Literature/TheDresdenFiles'' wizards who use BlackMagic (i.e. altering the [[ForcedTransformation body]] or [[MindRape mind]] of another human, [[{{Necromancy}} tampering with the laws of life and death]], [[TimeIsDangerous travelling through time]], contacting [[EldritchAbomination Outsiders]], or just using magic as a murder weapon in any way) tend toward this. The magic subtly warps the wizard's mind so they'll want to use it again, and each usage warps them more until all traces of morality, and often sanity, are gone. Case in point; Molly Carpenter used magic to force her friends Rosie and Nelson to quit using drugs, since they were having a child together and she wanted to protect both them and their baby and save Rosie from having another miscarriage...but she unwittingly damaged their minds and souls in the process, and Nelson ends up being driven insane. Thanks to that, Molly's now constantly tempted by the prospect of magically reading or manipulating people's minds in order to get results. There's a ''reason'' breaking any of the Laws Of Magic is a big freakin' deal.
152	** Dresden has had to deal with this for most of his life ever since he killed his EvilMentor in self-defense when he was a teenager. His struggles with not using magic against some foes reads a lot like an addict fighting the need for a fix. Various supernatural beings offering him more power like a bunch of drug-pushers don't help matters any. And then there's what happens when he becomes [[spoiler: the Winter Knight]].
153	* ''Literature/TheEnchantmentEmporium'' has [[InTheBlood sorcerers]], who turn out to be [[spoiler:male members of the Gale family]]. It's believed that if one starts out with enough power, this trope is inevitable, and a preemptive strike on any found would save the world a lot of hurt.
154	** A side-plot is Allie trying to save [[spoiler:her older brother David]], by trying to show how his rumored power can be used for good, in her battle against [[spoiler:Samuel Gale, the most recent one to get away]].
155	* Nicolae Carpathia in the ''Literature/LeftBehind'' books was like this when Satan indwelt him after his "resurrection" to fulfil his role as the Antichrist -- so much that, at the battle of Armageddon, Satan temporarily departs to tell Nicolae that he's getting too big for his britches!
156	* ''Literature/OldKingdom'': [[WildMagic Free Magic]] is all about single-mindedly forcing humans, spirits, undead, and reality itself to ''obey your will'', an {{addictive\|Magic}} high that quickly twists sorcerers into mad megalomaniacs. In ''Clariel'', Clariel gets lost in the rush of power just from using some UtilityMagic, and a Free Magic weapon nearly overwhelms her with fantasies of becoming an {{immortal\|Ruler}} SorcerousOverlord.
157	* Tends to happen in the ''Literature/{{Shannara}}'' books whenever magic is overused, most obviously in the backstories of the Warlock Lord (who got turned from WellIntentionedExtremist to power-mad tyrant), the Mord Wraiths (who got turned into near-mindless puppets of the sentient TomeOfEldritchLore known as the Ildatch) and the Shadowen (who became addicted to magic and fed themselves by leeching it out of both individuals and the Earth as a whole). The Warlock Lord is particularly hammy about it, too ("MORTAL CREATURE, I AM HERE!"), and many Shadowen are as well when dropping their [[BitchInSheepsClothing mortal guises]]; the Mord Wraiths don't really talk, but demonstrate extreme arrogance and obsessive devotion to their beloved book nonetheless.
158	* ''Franchise/StarWarsLegends'': In ''Literature/GalaxyOfFear'', the first [[spoiler:[[EvilTwin clone of herself]]]] that Tash Arranda meets is gleefully fascinated by the dark side, willing and wanting to kill and demonstrate her power. She has a wicked gleam in her eyes.
159	* In ''Literature/TheWheelOfTime'', the [[GodOfEvil Dark One]] provides its greatest servants the True Power, an EvilCounterpart to the One Power that fuels the setting's [[MagicAIsMagicA magic]]. Using it is described as equal parts agony, ecstasy, and sheer omnipotence; it's also supremely addictive and causes major SanitySlippage, to the extent that the one person to use it regularly ended up believing that ''he'' was the Dark One.

161
162	[[folder:Live-Action TV]]
163	* ''Series/BuffyTheVampireSlayer'':
164	** In "[[Recap/BuffyTheVampireSlayerS3E7Revelations Revelations]]", renegade Watcher Gwendolyn Post tricks the Scooby Gang into recovering the evil artifact the Glove of Myhnegon, and promptly becomes this trope.
165	--->''[after Miss Post has put on the Glove of Myhnegon and absorbed its power]''\
166	'''Faith:''' What's going on?\
167	'''Ms. Post:''' Faith... [[IronicEcho a word of advice]]: you're an idiot! ''[blasts Faith with lightning bolt]''
168	** Also Faith's StartOfDarkness. She became so frightening and psychotic that she would do Drusilla proud.
169	** Two words: "Bored now." These are the words [[spoiler:"Dark" Willow]] speaks just before [[spoiler:FlayingAlive the man who killed her girlfriend]] in "[[Recap/BuffyTheVampireSlayerS6E20Villains Villains]]". She then goes on a RoaringRampageOfRevenge trying to kill his two co-conspirators. Magic in the Franchise/{{Buffyverse}} is actually {{addictive\|Magic}}, and even [[spoiler:Willow herself]] states she's now a magic junkie.
170	* ''Series/Charmed1998'': In "[[Recap/CharmedS6E21WitchWars Witch Wars]]", Phoebe gets a crap-ton of demonic powers and promptly goes on a demon murder spree -- [[EvilFeelsGood and she enjoys it]]. Of course, she had been going though active power withdrawal for some time, and it ''was'' completely awesome, but you can kind of see why the PowersThatBe [[BroughtDownToNormal depowered her]] in the first place...
171	%%* ''Series/CobraKai'': Kenny pretty much expresses this verbatim as his motivation.
172	* ''Series/DoctorWho'': The Master in "[[Recap/DoctorWhoS30E17E18TheEndOfTime The End of Time]]". He gets resurrected, is constantly hungry (to the point where he devour an ''entire turkey'' in mere seconds), transforms nearly every human on Earth into a clone of himself (which gets undone via ResetButton), keeps talking about the drums in his head, has many (more than usual) [[HoYay homoerotic moments]] with the Doctor, and is last seen attacking [[spoiler:Rassilon, the Lord President of the Time Lords]] while chewing all of the scenery in sight, right before [[spoiler:he gets pulled into the Last Great Time War with the other Time Lords and Gallifrey.]]
173	* In ''Series/{{Earthsea}}'', after Ged experiments with shapeshifting into a sparrowhawk during his one-upmanship war with Jasper, Archmage Nemmerl warns the student body off of shapeshifting. He tells a tale of a wizard who liked shapeshifting into a bear so much that he gradually forgot he was originally human, killed his own son in bear form, and was finally hunted and killed by villagers.
174	* ''Series/OnceUponATime'': The longer [[EvilIsHammy Rumplestiltskin]] has his powers, the [[WithGreatPowerComesGreatInsanity worse]] he gets, especially after he loses his MoralityPet son. (While Mr. Gold, Rumple's depowered human Storybrooke counterpart, remembers who he is, he is much calmer and in control of himself than his fairy tale self.)
175	* A mundane variant occurs in ''Series/{{Oz}}'' with Yuri Kosygin. Kosygin started off as a poor immigrant who killed his boss in a rage when the man humiliated him in front of his wife, but Kosygin realized that he ''liked'' killing people and became a professional hitman. By the time he's sent to Oz, he has a body count in the dozens and he's clearly loving every second of it.
176	* ''Series/StarTrekPicard'':
177	** In "[[Recap/StarTrekPicardS1E08BrokenPieces Broken Pieces]]", Seven of Nine explains to Elnor that becoming the Borg Queen -- which would mean she would have absolute power over the Artifact itself and all of its drones -- is addictive, and she may not want to give up that power after she gets rid of the Romulans.
178	--->'''Elnor:''' You can release them when we win.\
179	'''Seven:''' They won't want to be released, and I... I might not want to release them.
180	** In the second season, when the [[GrandTheftMe Borg Queen takes over Agnes Jurati]], it's made clear that the assimilation process is actually catalyzed by her own endorphins.
181	* ''Series/Supergirl2015'': Several times, ordinary people who gain powers end up liking them so much, they don't mind the price they have to pay or the harm they cause. Dr. Grace Parker became disillusioned with life, believing that goodness was never rewarded. So when the personality and powers of Pestilence awoke within her, she eagerly accepted them, even being willing to allow her personality to be killed by Pestilence in order to obtain true power! Thief Pamela Ferrer becomes host to an alien symbiote called Menagerie, which eats hearts to stay alive. Pamela enjoys the enhanced strength and other abilities granted by Menagerie, which allows her to steal anything she wants, while gleefully allowing Menagerie to rip hearts out of people's rib cages.
182	* ''Series/{{Supernatural}}'': At the end of season six and the beginning of season seven, this has happened to [[spoiler:Castiel after he absorbed all the souls in Purgatory to gain the power to prevent ArchangelRaphael from restarting the Apocalypse]] -- although it's hard to tell exactly how much, since he's been [[WoobieDestroyerOfWorlds increasingly like this]] all season. His relationships with everyone became rocky partly because his friends [[JerkWithAHeartOfGold can all be jerks]], partly because he was growing [[LackOfEmpathy distant and inhuman]], and mostly because he [[JumpedOffTheSlipperySlope became ruthlessly practical]] and [[WellIntentionedExtremist overly focused on his cause]] even ''before'' [[spoiler:absorbing [[WithGreatPowerComesGreatInsanity too much monster-soul power]]. He gave a whole [[IDidWhatIHadToDo Villain Speech]] to Dean, [[MoralEventHorizon tortured an innocent woman to death]] for her blood, murdered a close friend (Balthazar) for telling the Winchesters where to find him to stop him, [[KickTheDog broke Sam's mind]] as a ''distraction'', and chose to [[DealWithTheDevil work with Crowley]] over Dean in the first place.]] Only after accessing the tainted power does [[spoiler:Castiel proclaim himself [[AGodAmI a new god]] and]] threaten his friends' lives. In season seven, [[spoiler:Dean's fears and continued willingness to kill Castiel are borne out by Castiel [[DisproportionateRevenge smiting angels and humans]] even before the voracious {{Eldritch Abomination}}s inside him tip him into a murderous rampage and he nearly [[SuperPowerMeltdown explodes]] before the unkillable monsters escape into the world.]]
183	[[/folder]]
184
185	[[folder:Religion]]
186	* ''Literature/TheBookOfMormon'':
187	** By the end of the Jaredites' final war, all the participants are caught in a HopelessWar that neither side can win (having already killed all the women and children), but they go on because they are "drunken with anger, as with wine." In other words, they've gotten so used to fighting and killing, that they can't do anything else by this point.
188	** Mormon writes to his son that the people around him have "lost their love, one for another," and that they "thirst after blood and revenge continually."
189	[[/folder]]
190
191	[[folder:Tabletop Games]]
192	* [[TabletopGame/MageTheAwakening Mages in the Chronicles of Darkness]] can develop the Megalomaniac condition if they fail a [[KarmaMeter Wisdom]] degeneration check. The only way to overcome Megalomania? [[JumpingOffTheSlipperySlope By provoking another Wisdom check.]]
193	* Overlaps heavily with ThisIsYourBrainOnEvil in ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'' whenever Chaos gets involved. Also typically comes with a [[LargeHam large slice of ham]] as the corrupted individual gleefully crosses the MoralEventHorizon.
194	** One of the funniest examples is when a [[OurGoblinsAreDifferent Grot]] has been hard wired into a [[HumongousMecha Killa Kan]] and [[ChewingTheScenery completely devours the scenery]] while killing everyone in sight.
195	-->"STOMP!!! KILL!!! CRUSH!!! STOMP!!!! STOOOOOOOOOOOOMMMMMMMMMMMPPPPPP! [[EvilLaugh HA HA HA HA HA!!!!!]]"
196	[[/folder]]
197
198	[[folder:Video Games]]
199	* In ''VideoGame/BaldursGateIII'' this occurs in the bad ending of [[spoiler:Astarion]]'s questline. [[spoiler:If allowed to usurp his [[IHateYouVampireDad vampire master]]'s DealWithTheDevil, Astarion is able to finally become a true vampire with none of the drawbacks. Unfortunately, as a spawn he was able to retain some of his humanity while [[OurVampiresAreDifferent D&D true vampires]] are AlwaysChaoticEvil. Upon completion of the ritual he ''immediately'' becomes a {{sadist}}ic megalomaniac plotting to TakeOverTheWorld, with all of his CharacterDevelopment going out the window.]]
200	* Most of the voice acting in the first ''VideoGame/BatenKaitos'' game is [[DullSurprise very wooden and monotone]]. However, during [[spoiler:Kalas']] FaceHeelTurn...
201	-->''[[{{Narm}} LOOK AT MEEEEEEEE!!! LOOK AT MY BEEEAAAUTIFUL WINGS! I'M COMPLEEEEETE!!!]]''
202	* ''VideoGame/TheDarkness'': Jackie describes having the Darkness as feeling like you're the star of your own action film, killing all the bad guys and looking good while doing it. That is, until you look around and realize everyone else is terrified, because you're not an action star, but rather a horror movie monster.
203	* This is one of the more... legitimate reasons BloodMagic and dealing with spirits is forbidden for mages in ''Franchise/DragonAge''.
204	* In ''VideoGame/EpiphanyCity'', [[spoiler:after absorbing the Dark Tree's powers, the first thing Superb Man says is that the villains were right--evil ''is'' more fun]].
205	* Happens twice in ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' GameMod ''VideoGame/{{Falskaar}}'':
206	** Brother Vernan really starts to go off the rails after experimenting with magic beyond his comprehension, all while believing himself in total control all the time and clearly on a power-high.
207	** The BigBad of the main quest, Yngvarr ''starts'' to behave this way upon discovering the [[spoiler:Heart of the Gods]] but [[spoiler:is killed before he can really embrace it]]. PlayedWith in that the artifact in this case is not evil by any means, but his use of it would definitely have been for malicious purposes.
208	* ''Franchise/FinalFantasy'' villains are fond of this trope, coupled with [[NietzscheWannabe nihilism]]. To name a couple, [[VideoGame/FinalFantasyVI Kefka]], and [[VideoGame/FinalFantasyIX Kuja]].
209	-->'''Kefka:''' I've tapped into the ultimate power. Observe...! Such magnificent power! You are like insects to me!
210	** Kefka is a subversion, as his personality stays exactly the same after gaining ultimate power -- which is bad, because he was a gleefully psychotic monster to begin with. Kefka goes from being a gleefully psychotic ''man'' to being a gleefully psychotic ''god''.
211	* On something of a meta level, it is not uncommon for players of ''VideoGame/GarrysMod Murder'' to devolve into a psychotic, screaming berserker if they are discovered to be the murderer. This does end up working against them if they are not careful, since a careless murderer may start screaming violent threats and fail to notice that they've left a large group of people alone.
212	* The reason the "canisters" in ''VideoGame/{{Geneforge}}'' are listed under both UpgradeArtifact and PsychoSerum--not only are they addictive, they're prone to causing [[AGodAmI egomania]], [[UnstoppableRage severe anger management problems]], {{Hallucinations}}, and, occasionally, BodyHorror.
213	* In the ''Franchise/KingdomHearts'' series, Ansem [[spoiler:Xehanort]] and Organization XIII are so Drunk on the Dark Side that sometimes it seems like the darkness is all [[https://www.youtube.com/watch?v=MzxQ61b-gOo they ever talk about.]] This even gets a LampshadeHanging in ''VideoGame/KingdomHearts3DDreamDropDistance''. It's to the point where only Riku has managed to use the power of darkness without falling into corruption; even Terra paid dearly for it in the end.
214	* In ''VideoGame/KnightsOfTheOldRepublic'', most of the students at the Sith Academy have this to various degrees. In fact, one way to get inside is to [[PayEvilUntoEvil murder one such student]], since he's just being a total dick and killing people at random because he can't get over how easy it is. In fact, in the very same game it's mentioned that [[ThisIsYourBrainOnEvil using the Dark Side actually changes a person's neurological patterns, much like prolonged drug use]].
215	* In ''Videogame/MegaManZero 2'', as the final boss [[spoiler:Elpizo]] is transforming into his OneWingedAngel form, he lets out a piercing scream, and then yells (in Japanese) "'''MORE POWER!!!'''" in a demonically distorted voice.
216	* Exposure to [[ToxicPhlebotinum Phazon]] causes this in the ''VideoGame/MetroidPrimeTrilogy''. In the third installment, Samus gets to experience it herself. It's still better than the [[GrandTheftMe alternative]], though.
217	** What makes Phazon even more insidious is that early stages of TheCorruption can be shrugged off by expelling excess Phazon by [[ATeamFiring shooting randomly]], which is highly likely to cause any and all allies to think you've either gone berserk or already succumbed to this trope.
218	* [[spoiler:Esher]] in ''VideoGame/MystVEndOfAges'' does this if you make the mistake of [[spoiler:giving him [[CosmicKeystone the tablet]]]].
219	* In ''VideoGame/OdinSphere'', the spell of Darkova transforms its user into a powerful three headed demon beast. The user is then cursed with a thirst for blood and pain, compelling them to destroy that which they love most.
220	* In ''Videogame/OverlordII'', when you drain [[spoiler:Queen Fay]] of her magic, she slowly begins to be corrupted by your dark magic, begging for you to continue and yelling at the Elves and Pixies for trying to save her. By the end she's driven completely insane and becomes a full-on FallenHero who joins you.
221	* ''VideoGame/RacingLagoon'' has Kyoji Nanba, [[NiceGuy the nicest guy you'll ever meet in the game]], end up looking like a zombie and speaking brokenly after he has taken drugs and driven a monster-tuned car. [[spoiler:Right after that, he drives straight into a barrier and gets himself killed.]]
222	* In ''VideoGame/SagaFrontier'', Asellus, a half-Mystic, can enhance and develop her Mystic abilities with three specific pieces of equipment. Developing them grants her more powerful skills and enhances her abilities when she uses [[EmergencyTransformation Mystic Change]], but she becomes more tyrannical and power-thirsty at the same time. [[spoiler:In the ending where she becomes a full Mystic (which is done by fully developing her powers with all three of the mentioned equipment pieces), she turns out to be an even worse tyrant than Orlouge (the Mystic overlord before her) ever was. On the other extreme, not developing her Mystic powers ''at all'' will allow her to become a human again.]]
223	* ''VideoGame/ShantaeHalfGenieHero'': After Shantae completes the Dynamo machine, it infects her with dark magic instead of destroying it. It turns out [[BatmanGambit Risky Boots knew Shantae would complete the plans]], and [[KansasCityShuffle tricked Shantae into getting the wrong blueprints from her]]. Nega-Shantae promptly tries infecting all of Scuttle Town with dark magic. [[spoiler:Luckily, Bolo, Sky, Rottytops and Uncle Mimic all pull Shantae back from the brink with ThePowerOfFriendship.]]
224	-->"I know what you can do... you can suffer! You can squirm like the pathetic maggots you are! Wallow in torment and pain forever in oblivion! Now beg! Beg for your very lives!"
225	* In the [[spoiler:Demon Path]] of ''VideoGame/SoulNomadAndTheWorldEaters'', [[spoiler:Revya]] does this, intoning "More... More power..." during some attacks, complete with a VoiceOfTheLegion.
226	* ''VideoGame/SpaceChannel5'': "Ulala! I needed your dance power you see, now we have all the power we need!"
227	* ''Franchise/StreetFighter'': Whereas Akuma uses the ''Satsui no Hadou'' (Surge of Murderous Intent) as a DangerousForbiddenTechnique while trying to keep the more negative tendencies of its use in check, Evil Ryu doesn't care and draws on it as much as possible, turning him a vindictively arrogant at best and outright murderous at worst BloodKnight. Oni is what would become of Akuma if he was as unrestrained as Evil Ryu when it comes to using the ''Satsui no Hadou'' and he is far worse about it than Evil Ryu ever was (promising nothing short of an OmnicidalManiac-level outcome).
228	* ''VideoGame/WarioWareGold'' involves another one of Wario's schemes to get money. This time, it's hosting the Wario Bowl tournament. The player is one of the many competitors. [[spoiler:Towards the end, Wario reveals the Wario Bowl was a scam for a prize that will never come, and uses the pot to turn into Wario Deluxe, plunging the world into darkness while announcing that the power is explosive before confronting the player in a final showdown, during which he cheats and uses lightning to hide the control schemes for four microgames. Luckily, the player is still able to beat Wario Deluxe after Lulu comes in to assist.]]
229	* In ''VideoGame/WorldOfWarcraft'':
230	** It is a quite common effect of demonic magic, especially for careless users. One boss in Magister's Terrace which, after charging up with a bit of it outright screams "YES! I AM A GOD!". His boss, Kael'thas, gets "unlimited power"-style quotes in both his appearances.
231	** In a meta vein, whenever any class or skill ends up buffed up significantly, players of that class will go on this trope completely. In one case, Shamans getting the ability to cast Chain Lightning with no pauses made the resulting light-show look ''just'' like Palpatine's Force Lightning. Flooding of Youtube with mashups of his quote from the page top with in-game footage promptly followed.
232	* Albedo from ''VideoGame/{{Xenosaga}}'' [[spoiler:firing Proto Merkabah at Second Miltia]] is an example of this.
233	[[/folder]]

235	[[folder:Webcomics]]
236	* Sarda in ''Webcomic/EightBitTheater'', episode 1171: "In fact, I didn't think it was possible, but now I hate you even more! The super powered evil I absorbed from Black Mage seems to be responsible. Who ''knows'' what kind of sadistic and impossible stuff I'll do now."
237	* ''Literally'', in Ava of ''Webcomic/AvasDemon'' case. After she ingests the [[BottledHeroicResolve potion]] [[DemonicPossession Wrathia]] gave her, she becomes so fuelled by the power and rage that she stops being scared and [[UnstoppableRage starts being furious]]. She proceeds to brutally massacre the followers of [[BigBad TITAN]] HQ. WordOfGod calls her Wrava in this state.
238	* Chloe in ''Webcomic/EerieCuties'', when she found a demonic AmplifierArtifact made for ''mature'' succubi -- which she isn't. She quickly grows powerful and restless, sliding out of control and [[spoiler:from an innocent crush to rather [[LoveMakesYouCrazy crazy]] to full demoning-out with urges to corrupt]] pretty quickly, ending with a breakdown and then a bad hangover after the "fun" ends.
239	* In ''Webcomic/{{Homestuck}}'', [[spoiler:Rose Lalonde does this after going [[TheCorruption Grimdark]]]].
240	* Yeager in ''Webcomic/{{Nodwick}}'' acted this way when he had won the power of [[Franchise/{{Highlander}} "The Quirkening"]], going so far as to threaten to kill Nodwick... well, ok, he's normally like that, but this time he meant to use his RealityWarper powers to ''really'' screw him over.
241	* [[spoiler:[[http://www.giantitp.com/comics/oots0635.html Vaarsuvius]]]] in ''Webcomic/TheOrderOfTheStick'', after making a DealWithTheDevil. At least initially. Soon after the character starts actually ''using'' that power, they feel nothing but frustration as resolutions to some plot threads have been reached ''without'' having them use it. And then finally when they try to fight the BigBad, an EvilSorceror that ''technically'' has less power, but is more than equal and is much more proficient in its use where it matters, they get stomped and lose all of that power. Though while the end result was far short of what the character imagined, they still managed to achieve a couple important things - and could have done more if not for the power-drunk rampage.

244	[[folder:Web Originals]]
245	* ''WebAnimation/{{Dreamscape}}'': Soon after training under [[WickedWitch Melinda]], Melissa saw knowledge as a sign of power, instead of a sign of enlightenment. She used her knowledge of TheDarkArts to carry out Melinda's evil bidding, but luckily Dylan and Alice gave her a change of heart.
246	* From ''[[http://www.newgrounds.com/portal/view/475655 The Dungeons And The Dragons]]'', a group of [[TabletopGame/DungeonsAndDragons D & D]] players have invited one of their mothers to sit in on a game to prove that roleplaying games aren't evil like [[ComicBook/ChickTracts Jack Chick]] says. It turns out that it's she herself who turns evil. We're talking ''Film/TheExorcist'' on '''[[ThisIsYourPremiseOnDrugs steroids]]''' evil.
247	* ''WebAnimation/{{RWBY}}'': Cinder's [[AmbitionIsEvil desire]] is to become strong, feared and powerful and she works for [[BigBad Salem]] because it gives her the opportunity to steal [[LegendFadesToMyth Maiden powers]]. While she only possesses half the [[ElementalPowers Fall Maiden's power]], she is able to [[TheHeavy execute]] Salem's plan for the destruction of [[ExtranormalInstitute Beacon Academy]] with great cunning, patience and adaptability, and obtains the Fall Maiden's full power. While recovering from [[AchillesHeel injuries inflicted]] by Ruby, she becomes increasingly intolerant of Salem's [[IControlMyMinionsThrough measured approach]] to pursuing her [[KillAllHumans goals]] and is warned by Salem to wait patiently for further power. Once unleashed to lead the infiltration of [[ExtranormalInstitute Haven Academy]], Cinder's leadership becomes increasingly [[SanitySlippage unstable]]. She revels in [[TheBully bullying]] others by flaunting her Maiden power and she watches the Spring Maiden's [[WeatherManipulation demonstration of power]] with an expression of undisguised lust; when Raven concludes that Cinder is [[FatalFlaw egomaniacal]], [[EvilGenius Watts]] agrees. [[spoiler:Cinder sacrifices caution and stealth for the chance to confront Ruby and uses the first opportunity she gets to try and steal the Spring Maiden's power for herself, revealing in the process that she's replaced her left arm with a Grimm arm that makes it easier for her to steal Maiden powers. As a result of her obsession, lack of patience and growing lust for power, she ruins Salem's plan; Haven Academy is rescued, the villains are forced to flee, and Cinder is cast into a bottomless abyss by the Spring Maiden.]]
248	* In the ''Literature/WhateleyUniverse'' there is an explicit mental illness that makes one more susceptible to this, [[ComicBook/HarleyQuinn Quinzel]]-[[ComicBook/NormanOsborn Osborn]] Syndrome, though it is something that can happen to almost anyone under the wrong circumstances. Apparently, it is often seen in conjunction with [[ScienceRelatedMemeticDisorder Deidrick's Syndrome]], [[HairTriggerTemper Hercules]] [[DramaQueen Syndrome]], or [[ChronicVillainy certain expressions of Galahad Syndrome]], which only ups the insanity quotient all around.

251	[[folder:Western Animation]]
252	* PlayedForLaughs in the ''WesternAnimation/AdventureTime'' episode "[[Recap/AdventureTimeS2E8CrystalsHavePower Crystals Have Power]]" when [[spoiler:(somewhat) CoolOldLady Tree Trunks becomes Quartzion the Crystal Queen and]] attacks Finn and Jake, seemingly for no reason than she suddenly has power.
253	-->'''Jake:''' [[IfIHadANickel If I had a penny]] for every time someone went crazy while hopped up on magical power, I'd be UsefulNotes/AbrahamLincoln!
254	* ''WesternAnimation/{{Fangbone}}'': In the episode "The Keeper of Toe", we are introduced to Wargrunt, the former keeper of [[SealedEvilInASixPack Venomous Drool's elbow]]. The burden of guarding it led her to use its evil magic for personal gains, which led to her being banished from her tribe who took the elbow from her, until it was taken by Drool's monsters.
255	* In the Season 2 finale of ''WesternAnimation/JusticeLeague Unlimited'', "[[Recap/JusticeLeagueUnlimitedS2E12DividedWeFall Divided We Fall]]", Lex Luthor becomes this way [[spoiler:after merging with Brainiac]]. He mentions that in that state, he has power, and he likes it. Throughout season 3, he constantly tries to [[spoiler:reactivate Brainiac from a small piece of technology-covered rock]] to regain that feeling.
256	* ''Franchise/MyLittlePony'':
257	** ''WesternAnimation/MyLittlePonyEscapeFromCatrina'': The titular villain is addicted to her witchweed potion and the magical power it gives her, which her only friend Rep laments has warped her personality into her current cruel and vicious self.
258	** ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': This happens with [[RivalTurnedEvil Trixie]] while wearing [[ArtifactOfDoom the Alicorn Amulet]] in "[[Recap/MyLittlePonyFriendshipIsMagicS3E5MagicDuel Magic Duel]]". She's a pretty LargeHam to begin with, and the Amulet not only drastically increases her power but corrupts her mind. In this case, it's reversible because all it takes is removing the Amulet and giving her a bit of time to come off the high.
259	* ''WesternAnimation/SkeletonWarriors'': Baron Dark can turn anyone the least bit corruptible into a Skeleton Warrior with a touch. The Skeleton Warriors ''really'' enjoy being unkillable undead monstrosities. So much so that at the end of one episode, two of Dark's henchpeople who had their humanity restored beg him to turn them into Skeleton Warriors again.
260	* PlayedForHorror in ''WesternAnimation/StarWarsCloneWars''. [[spoiler:After spending most of the fight evenly matched with Asajj Ventress, Anakin begins drawing on the Dark Side just as Ventress was about to strike the killing blow, thus disarming her of one lightsaber, force-pushing her, and grabbing said lightsaber with the Force. He then runs at her screaming in rage and proceeds to parry each move she makes, before she falls on her back and receives a NoHoldsBarredBeatdown from Anakin until the platform she's on breaks and falls into the abyss below, with Anakin letting out a final roar of rage. All of this is meant to show Anakin slipping into the Dark Side further and further, {{Foreshadowing}} him becoming Darth Vader.]]
261	* Happens to Ezra in the ''WesternAnimation/StarWarsRebels'' episode "[[Recap/StarWarsRebelsStepsIntoShadow Steps Into Shadow]]", where he's been secretly taking lessons from a [[ArtifactOfDoom Sith holocron]] for six months. It grants him greater aptitude with the Force to the point where he's able to inflict PsychicAssistedSuicide on an Imperial pilot, and gets him promoted to Lieutenant within the Rebel Alliance but [[DarkSide makes him arrogant and impulsive]]. As a result, he makes short-sighted decisions that lead to failing his first mission without any oversight and [[BreakTheHaughty gets him chewed out and demoted]].
262	* ''WesternAnimation/StormHawks'': Both [[BigBad Master Cyclonis]] and [[TheDragon the Dark Ace]] suffer this in the finale. In the midst of both villains' VillainousBreakdown, Cyclonis attempts further empowering the Dark Ace by drawing on and redirecting Far Side energy through herself into him. It isn't enough for the Dark Ace to challenge the heroes, and he's reduced to ranting and raving at Cyclonis to give him "'''MORE!'''" She complies, but seemingly herself gets carried away by the power, and doesn't notice she's overloading the Dark Ace with too much energy until he implodes.
