When LightIsGood and DarkIsEvil, it was held that just as darkness was the absence of light (which is accurate), so evil was the absence of good. Where there was good, therefore, evil could not stand.

Anything "sufficiently" good didn't need to be [[DumbIsGood intelligent]] or [[GoodIsImpotent powerful]] in order to protect itself because good was invincible enough just being ''there''. Good things had "auras" of purity or goodness that could slice and dice evil [[CharacterAlignment or evil-aligned]] beings like blades, atomize them entirely or at least leave a second or third degree burn. Even the [[EldritchAbomination greatest threats]] would run off screaming like nursery girls at the mere rumor of their presence, ignoring the fact that the objects of their fear were otherwise absolutely harmless.

Often times, [[GoodIsImpotent the more proactive heroes were unable to have such an effect]] due to lesser purity, which left [[IncorruptiblePurePureness the local priest, nun or pure child]] to act as a DeusExMachina for when they get overwhelmed by the [[LegionsOfHell legions of darkness]]. Objects touched or blessed by objectively good characters could gain similar protective qualities, and religious sanctuaries were the mightiest of fortresses when evil was on your tail.

This injurious side of good is becoming rare as readers and viewers learn to take GreyAndGrayMorality for granted, but expect very strong showings in religious literature. A PuritySue (or any [[MarySue Sue]] in general) may have this trait, but often without the [[GoodIsBoring restricted freedom]] that traditionally comes with it.

Note that [[ClapYourHandsIfYouBelieve differences of belief]] weren't ever an issue because it was taken for granted that the good thing or person really was good, and not just belonging to the majority faith, sometimes resulting in a [[{{Anvilicious}} rather heavy handed]] [[AnAesop Aesop]] for characters who ''were'' from the dominant church or [[CrystalDragonJesus local equivalent]].

An [[OlderThanPrint old]] and DiscreditedTrope, with some exceptions. It's largely been absorbed by the SmiteEvil trope. It's an interesting cultural study; people no longer think that Good, itself, is invincible, but used correctly it can really kick ass! If it is used in modern works, it's usually in ones centered squarely on the Idealistic side of the SlidingScaleOfIdealismVersusCynicism, or where the baddies ARE shadows/darkness and thus are WeakenedByTheLight. It's often utilized alongside OnlyThePureOfHeart.

SubTrope of SupernaturalRepellent. SuperTrope to HolyBurnsEvil. The inverse of this trope is AllergicToEvil (for people) and CrossMeltingAura (for [[ProtectiveCharm holy artifacts]]). Might be a reason for TooSpicyForYogSothoth. See also ReviveKillsZombie. Contrast with HolyHandGrenade where it is the power of Light instead of Goodness which burns; a crucial difference in a setting where Good is not equivalent to Light and where religion and purity might actually be oppressive or villainous. Also contrast HolyIsNotSafe where the intensity of the holiness will damage or consume anyone who fails to meet its rather stringent standards.



[[folder:Anime and Manga]]
* A secularized version is played for laughs in ''{{LightNovel/Slayers}}'' when Lina turns LoveFreak Amelia loose on Xellos. Since Mazoku in the slayerverse feed on negative emotions the [[GenkiGirl full unbridled effect of Amelia's sheer perkiness]] (backed up by a rather insincere-sounding Gourry and Zelgadis) is enough to completely debilitate one of the most powerful evil characters in the series.
* The character known as "The Oracle" from ''Anime/SpiderRiders'' has the ability to prevent her power form being abused by those who use it. Mostly she dosen't actually hurt anyone, she just blinds them with a flash of light.
* In the [[{{Filler}} Doma Arc]] of ''Anime/YuGiOh'', the Pharaoh defeats the Orichalcos God with the power of the goodness in his heart.
* In ''Anime/TheSnowQueen1977'', the Snow Queen is burned alive when Gerda and Kai pray.
* PlayedForLaughs in ''LightNovel/HighSchoolDXD''. Praying to God, or being the target of a benevolent prayer, causes demons sharp headaches. Even after becoming demons, Asia and Xenovia remain devout, and [[AmusingInjuries frequently forget this]]. Until Issei asks ArchangelMichael to let them pray without the pain.

[[folder:Comic Books]]
* The page image comes from a ''ComicBook/WhatIf'' ComicBook/SilverSurfer story, "What if the Silver Surfer had not escaped Earth?" (v2 #22). Mephisto finally acquires Silver Surfer's soul and brings him into Hell. He then makes the mistake of slaying his physical body, realizing too late that the Surfer's soul is so good and pure that its light hurts him. Since Surfer already agreed to be in Hell forever, Mephisto will burn "until time's end".
* In the Italian [[ComicBook/MickeyMouseComicUniverse Mickey Mouse comic book]] story ''Topolino e il cavaliere senza tempo'' ("Mickey and the knight out of time"), Mickey meets Flagellus, a "Knight of Evil" whose sole presence causes chaos and disaster to spread around him. After turning Pluto into stone and burying Goofy, he is about to kill Mickey in a sword fight but agrees to let him live if Minnie becomes his bride... and she accepts without hesitation. As he takes her hand, he yells in pain and fades off into nothingness, because ''"her good is more powerful than his evil"''.
* Creator/MarvelComics' The Brood are an entire alien race that, until recently, screened out compassion by killing any of their offspring that showed potential for it. Brood can learn compassion, but having it suddenly forced on them (via psychic projection for example) will ''kill'' them.
* Mephisto really doesn't learn. Being (possibly) Marvel's version of {{Satan}} he likes nothing more than corrupting the souls of goodly heroes by offering them deals, then claiming said souls for eternal torment. He once pulled such a deal with ComicBook/BlackPanther, but forgot to take into account two things: 1, the deal was made not for personal gain but to aid others, making it a selfless sacrifice and thus not "corrupting" him; and 2, T'Challa's soul was already bound to the Panther Spirit, and thus the soul of ''every other Black Panther in history''. Whereas Silver Surfer's soul merely "burned" him, that much IncorruptiblePurePureness threatened to ''obliterate'' him until he released T'challa from the deal. AllAccordingToPlan.
* ''ComicBook/RequiemVampireKnight''
** Weaponized due to the EvilVersusEvil nature of the setting, with such things as holy water sprayers, tortured martyrs that generate an anti-evil field and a warhead containing an angel. Unfortunately, there are some issues, like the holy water pipeline coming directly from the Vatican, and what with all the PedophilePriest scandals, it's not exactly holy anymore.
** The most powerful weapon used against the good guys (lemures, the ghosts of people who died because of another's evil) is unleashed by Dracula by breaking a man's neck. With his death, the lemures can pass on, [[UsefulNotes/AdolfHitler while the man's blood flows under his nose...]]
* Even DC's variation of the devil isn't immune to this trope. Neron of ''ComicBook/UnderworldUnleashed'' sought to obtain the soul of [[ComicBook/{{Shazam}} Captain Marvel]], as it was the most pure of the other heroes' souls. When Captain Marvel surrendered it selflessly, its pureness burned him and he quickly returned it to him, forcing Neron to retreat.

[[folder:Fan Works]]
* In ''ComicBook/{{Supergirl}}'' story ''Fanfic/HellsisterTrilogy'', [[ComicBook/{{Legion Of Super-Heroes}} Mordru]] dies when he comes in contact with a huge mass of sacred light. It's speculated The Presence -Franchise/TheDCU's supreme {{God}}- was within it.
-->He came in contact with The Light.\\
Whether he saw a Presence within, or not, will not be known, at least on this side of the veil. For, whenever a being of his evil comes physically in contact with a force of purity that strong, there can be no resisting its power.\\
In the end, the force-field might have been of some use in delaying the outcome for a fraction of a second. But only that.\\
He exploded.
* While [[JourneyToTheCenterOfTheMind inside Socrates' mind]] to fix a fault in his transmitter chip in ''Fanfic/CalvinAndHobbesTheSeries'', the protagonists find Socrates' dark side inside an AbsurdlyBrightLight. When the chip is fixed, the light gives way to reveal a colorful field, which causes the dark Socrates to scream and dissipate.
--> '''Andy:''' [[Film/TheWizardOfOz What a world, what a world.]]
* In ''MyLittlePonyFriendshipIsMagic,'' ''NightmaresAreTragic'', the [[DemonicPossession Night Shadows]] are damaged by sufficiently strong love. When Luna realizes that her [[spoiler:OneTrueLove has finally been reborn and is threatened by Nightmare Moon]] she uses this to [[spoiler:break the Night Shadow's hold on her soul and begin FightingFromTheInside to keep it from using their shared form to kill the Mane Six]].
* In ''Fanfic/TheUltimateEvil'' (an AlternateUniverseFic of ''WesternAnimation/JackieChanAdventures''), in addition to the canonical Pan'Ku Box, we're introduced a DemonSlayer who has several weapons that hurt demons on touch (like magical dust and blessed daggers). However, her crucifix [[NoSell doesn't work on]] Bai Tza.

[[folder:Films -- Animated]]
* Chernobog in ''Disney/{{Fantasia}}'' is driven away by the forces of "the sacred".
* ''WesternAnimation/YellowSubmarine'': The Blue Meanies hate music. "They shrink at the very sound".

[[folder:Films -- Live-Action]]
* Played with in ''Film/TheMummy1999'', when Beni holds up a series of holy symbols hanging around his neck -- accompanied by appropriate incantations -- to try to find one that will fend off the titular monster. (Turns out Imphotep doesn't fear crosses or stars of David ... just cats.) One of them does still sort of work, however; Imhotep recognises "the language of the slaves", ie Hebrew, and decides Benny might be worth keeping around.
* In ''Film/FrightNight1985'', Peter Vincent brandishes a large, ornate cross at Jerry, who simply laughs at him. "You have to have faith for this to work on me," he tells Vincent. Charlie moves in with a small, simple one, but with the faith required and Jerry flinches back, [[spoiler:until his zombie protector shows up.]]

* More than one powerful baddie in ''Literature/TheLordOfTheRings'' had a vulnerability to Elvish invocations of the Valar.
** Gollum feels pain when he comes into physical contact with the enchanted rope the Elves gave to Sam. Also his aversion to the sun might qualify.
** So does the Nazgûls' fear of running water; the power of Vala Ulmo still runs strong in Middle-Earth's waters.
** The Silmarils of ''Literature/TheSilmarillion'' burn anyone of evil heart who comes into contact with them, as they contain the trapped holy light of the lost Two Trees. This is a plot point several times -- Morgoth burns his hands when he originally steals them and is forever in pain afterwards (but still covets them and wears them in his iron crown), the great wolf Carcharoth goes on a panicked rampage being burned from the inside out after [[TooDumbToLive swallowing one]], and when the Silmarils' creator Fëanor's sons Maedhros and Maglor find that stolen Silmarils burn them, they realise that their evil deeds mean they have lost all right to them.
** The light in the vial that Galadriel gives to Frodo, which Sam uses against Shelob? That light is the concentrated essence of one star - but that's not really a star at all, it's the last non-lost Silmaril, carried by Eärendil in the sky. And the Silmarils are made from the light of the Two Trees, and therefore the light of Ilúvatar itself. By the Transitive Property of Holiness, ''Sam fights Shelob with the light of God.''
** Then, it's subverted at Mount Doom, where Sam pulls out the vial for some kind of help... only to watch in terror as it grows dim. Mount Doom, apparently, is an evil so absolute, even the (reflected) glory of God gives way.
** Corrupted beings such as orcs and Gollum cannot eat the Elven waybread ''lembas'', a magical foodstuff made with corn provided by one of the Valar.
* ''Literature/HarryPotter''. ThePowerOfLove his mother gave him is powerful enough to melt faces and make the most powerful of curses backfire. However, since the universe is mixed with MagicAIsMagicA, the BigBad is able to take steps to prevent its effects against him.
** Voldemort is still hit with this at the climax of book five, when he [[spoiler:succeeds in possessing Harry. He tries to goad Dumbledore into attacking Harry in hopes of killing them both at once. Harry is in so much pain that he finds himself wishing Dumbledore would do it, since it would mean he could see Sirius again - and Harry's thoughts of Sirius cause Voldemort so much agony that he never even ''tries'' the possession tactic again.]]
** The Dementors can be fought off by summoning a creature made of concentrated positive emotion (love or happiness). Dementors are embodiments of depression they qualify as MadeOfEvil, and that Patronuses are made of good (and are immune to all Dark magic).
* In ''Literature/GoodOmens'', the demon Ligur is rather nastily killed by holy water. Holy water's typical effect on demonic entities such as demons and vampires in fantasy fiction is a common type of this trope.
** Something of a subversion in that it wasn't sprinkled at him with a chant by a robed holy man; it was weaponized into booby traps and squirt guns by another demon who premeditated his defense.
** The good/evil lines on ''Literature/GoodOmens'' are all blurred, which is sort of the point; Crowley isn't very evil, but he is still a demon and he still treats holy water with the caution a chemist gives to concentrated acid.
* All over the place in ''Literature/LeftBehind'', of course, but most {{squick}}ily in ''Glorious Appearing'', where a would-be rapist of a returned immortal Christian bursts into flames--but only after being allowed to begin the attack, and even though traditional narratives allow for less violent methods of defense, such as intangibility.
* In the ''Literature/InheritanceCycle'', this is how [[spoiler:Eragon]] defeats [[spoiler:Galbatorix]]. The former casts a spell on the latter that [[spoiler:causes him to feel empathy, and thus Galbatorix commits suicide, having been driven mad (well, more than he already was) from feeling the pain of the hundreds of dragons and thousands of people he slaughtered.]]
* The protagonist in ''Anime/SorcererOnTheRocks'', Shibas Scotch, is such a bad person that being in a nice place like a clear meadow on a sunny day makes him ill.
* In ''Literature/TheDresdenFiles'',
** The [[EmotionEater White Court]] of vampires is harmed if their victims express the positive emotion that is anathema to what they feed on: The lust-eating Raiths are harmed by true love, the despair-eating Skavis by true hope/optimism, and the fear-eating Malvola by true courage and bravery. Things get complicated when [[FriendlyNeighborhoodVampires Thomas]] falls in love with his favorite "food". While Thomas wouldn't normally eat off a person who has the protection of love, he loves and wants Justine so badly, he and his inner demon try to feed off of her on instinct. Also, in a twist, if the offspring of a White Court vampire experiences their opposite emotion before they start learning how to truly 'feed', they never develop into vampires and turn human instead.
** The Knights of the Cross, wielders of swords into which the nails from the Crucifixion have been worked, are exceptionally powerful against supernatural evils for precisely this reason. Interestingly, their swords names translate as Hope, Faith, and Love, which the Bible lists as the final things of good at the end of the world.
*** One Red Court vampire's[[note]]These are not succubus-type as the White Court, rather living bat-like beasts who masquerade as humans[[/note]] hand actually caught on fire when she touched Micheal, the "Fist of God", at a neutral grounds party. She wasn't even attacking him, just casually touching him in an attempt at mind games. Needless to say it backfired horribly for the deranged incestuous monster.
** The Black Court, who are the basis for the classic undead Vampire, burn when in contact with holy items. Harry even used a water balloon filled with holy water on one that attacked him in his car. The creature's face partially melted.
** Among demons, holy items and rituals work against most any evil so long as the wielder has ''faith'' in the item or symbol. So Harry would gain no protection from a cross, unlike Michael, but he would gain it from his silver pentacle, a symbol of his faith in good magic and order. Likewise, only a few Medicine Men in the Ute tribes and others from the South West USA would have the knowledge to call on the rituals to banish a {{Skinwalker}}.
** Then among the Fallen Angels [[spoiler:this is averted. When Harry had the shadow of a Fallen inside his head, he could go into a church with no trouble. Eventually, he postulated it wasn't this trope that caused them to avoid being in churches longer than needed. It was being on the holy ground made them remember His Love and Glory, the purpose they once had, the fulfillment they had at acting in His Name, and finally [[MyGodWhatHaveIDone asking themselves what if siding with Lucifer was a mistake and all the angel had done was for nothing]].]]
** Among the Angels arsenal is the opposite of Hellfire: Soulfire, the fires of creation. The ancient force that created the Universe and Reality. When used by a human, it makes magic and one's will power more ''real'' giving it a boost of incredible power, at the cost of reducing one's soul (it can grow back, just do some good-for-the-soul things). [[spoiler:Using Soulfire-infused attacks Harry almost defeated a {{Skinwalker}}]].
* Played relatively straight in ''Literature/TheStand''. Trashcan Man is positively frightened by his dreams of Mother Abagail (who pities him in hers, even when she can't remember him). Flagg loses all of his composure and power around the Free Zoners, even traitors like Harold and Nadine.
* In Creator/LordDunsany's ''Literature/TheCharwomansShadow'', the false shadow is driven off by the [[GoodShepherd priest]] and his bell.
* When the Dragon Reborn from ''Literature/TheWheelOfTime'' finally accepts his reincarnation and remembers his previous life, he seems to have gained this ability. Darkfriends can't even look at him, it burns so much. Everyone else perceives it as a bright aura, almost a warping of the air infused with light itself. It's quite possible that such abilities are part of his purpose, because the Dragon exists to fight the Dark One, over and over. Just as the Dark One's power warps the air with darkness and gives off the essence of ruin and destruction, the Dragon's power warps the air with light and gives off the essence of hope and salvation.
* John Galt from ''Literature/AtlasShrugged'' is supposed to be so awesome that merely talking with him and beholding his face makes any evil character very uncomfortable with all the self-deceptions that they live with. This effect is worst for the most self-deceived characters like Eugene Lawson and Jim Taggart--the latter of whom [[VillainousBSOD actually loses his mind when he is interrogating Galt]].
* In ''Literature/DemonAMemoir'', this trope is both subverted and subsequently played straight in the same scene: Clay goes into a church, hoping [[FallenAngel Lucian]] won’t be able to follow him on; Lucian [[OurDemonsAreDifferent laughs at the idea]], but does comment that the prayers of people inside the church give him a headache.
* Deconstructed in the ''Literature/NightWatch'' series, where the "White Blade" spell is ''supposed'' to harm only Dark Ones and "evil beings". Too bad its criteria of evil is so stringent that "you'd have to be a Tibetan monk who'd spent decades meditating and subduing his passions for the blazing blade to spare you". A young Light One strikes some brainwashed human mercenaries with the White Blade, only seeking to destroy their weapons, but it slices them in half instead. The Light One cannot bear the brunt of his deed and self-terminates.
* In ''Literature/TheChroniclesOfThomasCovenant'', Lord Foul the Despiser is the BigBad, the GodOfEvil ''and'' TheAntiGod, wielder and in some senses embodiment of ThePowerOfHate and centuries-spanning chessmaster extraordinaire, but there is one power that he [[EvilCannotComprehendGood cannot understand]] and cannot ''withstand''. It's not Magic or Law and certainly isn't Despair - [[spoiler: it's ''joy''. When Covenant and Foamfollower confront him at the end of the first arc, it's Covenant's wild magic that separates Foul from his ArtifactOfDoom, but it's Foamfollower's good-hearted laughter in the face of annihilation that finishes him]].

[[folder:Live-Action TV]]
* Used and subverted on ''Series/BuffyTheVampireSlayer'': Vampires have weaknesses to holy water, crosses, and the like, ([[WordOfGod apparently]], because Christians are the ones who have done the most monster hunting). But said protection in no way extends to the people fighting against them. In fact, the blood of a Slayer is said to be particularly tasty to vampires (and, if Spike is to be believed, is a potent aphrodisiac for them as well).
* Holy water is used to great effect in ''Series/{{Supernatural}}'' (sanctified sprinkler system) and demons flinch when they hear the name "Christo".
* Both crosses and stars of David annoy vampires in ''Series/{{Being Human|UK}}.''
* Gloriously revised in the ''Series/DoctorWho'' story ''The Curse of Fenric'', set during World War II: In this story it's not the ''symbol'' that's important, it's the bearer's ''faith in the good that that symbol represents.'' As a result, the vampire/zombie haemovores are untroubled by a priest holding up a cross, because the horrors of war have eroded the priest's faith. But the Doctor is able to repel a mob of them by reciting all his companions' names (from Susan up through Ace), and a patriotic Soviet soldier fends off some more by holding up the hammer-and-sickle badge from his uniform!
* On MightyMorphinPowerRangers, the Zeo Crystal is harmful to any evil being who touches it. Supposedly, Lord Zedd lost his skin when he tried to pick it up.

[[folder:Mythology and Religion]]
* Many, many, ''many'' tales of Catholic saints, including St. Margaret of Antioch, who was swallowed by Satan in the form of a dragon. However, her innate goodness (and the crucifix she bore) proved too much for Old Nick's saurian stomach to handle, and the dragon burst asunder. St. Margaret became the patron saint of childbirth, which should bring [[{{Franchise/Alien}} disturbing]] [[ChestBurster images]] to the mind of any pregnant woman.
* Many Swedish folk tales had mythological creatures of differing degrees of malevolence who could be stopped, harmed or driven off by holy things, including prayer, the sound of church bells, drawing a cross on the ground, and in one tale casually saying "cross".
** The scandinavian version of Trolls are especially notable for this, as they will turn to stone in sunlight and be driven off by the sound of church bells. However, it should be noted that trolls are ''not'' AlwaysChaoticEvil, and in some versions are just symbols of Scandinavia's pagan past, not good nor evil. In these stories, they're perfectly fine in sunlight but have withdrawn to the mountains to avoid the christian settlers.
** The scandinavian version of the Sirens, known as a "Rå", are mean-spirited tricksters who enjoy tormenting humans and appear as beautiful women with fox tails or tree bark on their back. Their anthisesis is christianity, and can be driven off by prayer, or in one story, by a man saying "in Gods name" while telling who he thought was his wife that he was going to bed for the night.
* Unicorns, who were all but invincible to fight, could be tamed and therefore conquered only by purity. It was said that the touch of a virgin maiden who was pure of heart could do the trick.
** Which is actually a joke---a mythical creature (a unicorn) subdued by another mythical one (a pure maiden).
* According to exorcists, exorcism is so painful for demons that they find Hell preferable. Granted, the exorcism isn't exactly easy on the person who's possessed either.

[[folder:Tabletop Games]]
* Fairly standard abilities for good characters of various kinds in ''TabletopGame/DungeonsAndDragons''.
** However, there are plenty of inversions. For example, a Good-aligned character trying to touch an Evil artifact suffers penalties identical to an Evil-aligned character touching a Good artifact. The same holds true for other properties, such as Law and Chaos, Fire and Cold; indeed, D&D has the trope generalized to Extreme Hurts Extreme.
** In editions prior to 3.5, played completely straight by the 'smite evil' ability, which does what it says and can add damage to essentially any form of physical contact. In the expansions that led to 3.5, corresponding abilities for evil characters were later added.
** Turn Undead is another relatively straightforward example, with the very presence of a good character potentially destroying inherently-evil undead creatures outright while an evil character using the same ability doesn't have any comparable effect.
* The High Elf Everqueen in ''TabletopGame/{{Warhammer}}'' kills demons and undead just by her presence.
** Amazingly, it happens also in the {{Grimdark}} ''TabletopGame/{{Warhammer 40000}}'': to humans, the Emperor is absolute good... And munitions filled with byproducts of the Golden Throne he's trapped on (AKA the Emperor's holy ''crap'') can hurt demons.
** Subverted with blanks, who also hurt daemons and warpspawn through their mere presence... and who inspire UncannyValley in normal humans and unspeakable horror in psykers, because they have negative Warp presence, thus feeling inherently "wrong" to human senses.
* The Merit: ''True Faith'' in Creator/WhiteWolf's original ''TabletopGame/TheWorldOfDarkness'' allowed certain virtuous characters to harm evil entities by touch, deed or (at high levels) presence alone. The behavior required to match the Merit's greatest levels put them (theoretically) beyond the reach of most player characters, but - as with an game - exceptions were probably common.
** A less literal example: one of the suggested effects of a mage's enlightenment is that drinking their blood in the quantity necessary to gain a blood point reduces the vampire to ash instantly, meaning that the purity of an enlightened soul is more damaging to a vampire than walking into the sunlight at high noon on a clear day.
** In the ''TabletopGame/NewWorldOfDarkness'', a mortal with high levels of humanity and the level of virtue that implies gains bonuses in interactions with ghosts and spirits that represent a 50% increased chance of winning any social conflict (which is the primary way to subdue or eliminate such creatures).
* In ''TabletopGame/{{Exalted}}'', the Unconquered Sun is the cosmic embodiment of virtue. As a result, it is within his power to deem which sorts of beings in Creation and beyond count as "creatures of darkness" (usually demons, the undead, and [[TheFairFolk Raksha]]). His chosen, the Solar Exalted, thus have access to Holy Charms that allow them to do ''extremely'' grievous damage to said creatures of darkness. This is something of a subversion, however. The Sun has authority to declare whomever he so chooses to be Creatures of Darkness without any due process. If a Lawful Good Paladin style character pissed him off sufficiently, she could be declared a Creature of Darkness no matter how many kittens she saved or old people she helped across the street. It is only the Sun's commitment and restraint that prevents him from abusing this power.[[note]]When we finally get a look at the Unconquered Sun's stats in ''Glories of the Most High'', it is evident that he has good reason not to do so: declaring someone to be a Creature of Darkness out of personal dislike would force him to suppress his Temperance, robbing him of his complete invulnerability to any form of damage.[[/note]]
** Other classes of Exalted also can deploy Holy magic, though the Solar versions tend to be the most directly potent of the bunch as usual.
** For more detail, see the game's entry in DetectEvil.
* Slightly Zigzagged in ''TabletopGame/TheDarkEye'', where demons take additional harm from priests, holy objects and grounds, but the effect is not restricted to good deities.

[[folder:Video Games]]
* ''Videogame/KingdomHearts'' plays this very straight in the ending of the first game when the light of the titular power destroys the game's BigBad.
* Giygas is defeated by way of this trope in both ''[[VideoGame/{{Mother1}} Earthbound Zero]]'' and Videogame/EarthBound. In the first game, [[spoiler:he's overwhelmed by the love bound inside a song his adopted mother used to sing to him,]] and after he's become too powerful, it takes [[spoiler:the combined prayers of everyone in the game universe, as well as those of ''the player'']], to defeat him once and for all.
* In ''VideoGame/DisgaeaHourOfDarkness'', optimism and [[AllergicToLove love]] physically weaken Laharl, resulting in reduced stats in one fight when his enemy takes advantage of this.
* ''Franchise/TheLegendOfZelda'', with the Master Sword, "The Blade of Evil's Bane", and the Light Arrows.
* ''Videogame/KingdomOfLoathing'' has the [[ElementalRockPaperScissors Bad Spelling]] monsters, hurt by reading the dictionary.
* Good ''irritates'' evil in the video game of ''VideoGame/TheDarkness''. The Darkness refuses to manifest itself around the subway stations full of normal people, and if you try it'll complain that it finds the people too boring to attack; the Darkness is attracted to darkness, and even the metaphorical darkness of the heart is preferable to it.
* In ''VideoGame/KingsQuestIVThePerilsOfRosella'' the way to rid yourself of the villain is to shoot her with Cupid's arrow, which (probably unbeknownst to Rosella herself), kills her, as something so foul and fueled by hate cannot survive the experience of love.
* On meeting [[KnightInShiningArmor Casavir]] in ''Videogame/NeverwinterNights2'', [[CuteMonsterGirl Neeshka]] remarks that paladins always make her spots itch.
* In ''Videogame/AlanWake'', LightIsGood and DarkIsEvil are to be taken literally. Rub those brain cells together and [[WeakenedByTheLight see what you come up with]].
* In ''[[VideoGame/{{Doom}} Doom 3]]'' hell starts leaking into our world (or Mars in this case) causing insanity and other problems. It is suggested this is also happening in reverse, although for them it's probably not so much hurt as mildly annoy.
* In ''VideoGame/KirbyStarAllies'', Kirby is able to toss Friend Hearts at any enemy with an ability that can be copied to have them fight at his side. For the most part, trying to hit anything else with a heart will just result in it fading away, but tossing them at the final boss [[spoiler: Void Termina]] will actually cause a small amount of damage to it, which is appropriate when considering it's MadeOfEvil.
* In ''Videogame/WorldOfWarcraft'', the Paladin's "Exorcism" spell was guaranteed to get a critical strike when used against a demonic or undead opponent(excluding the playable Forsaken) back in the latter parts of the Wrath of the Lich King expansion and the Cataclysm expansion.
* The main villain of Gobliins 2 "Amoniak" is defeated by drinking a goodness potion, but instead of turning good, it kills him. This is lampshaded in the third game when Blount is temporarily sent to the land of the dead, you find "Amoniak was here" graffitied on the wall.

** The famous instance of Torg hiding from a bunch of demons inside a literal circle of goodness. He'd taunt one of the stupider demons into trying to leap at him, and his arms would catch on fire, prompting the classic line, "I'M BURNING WITH GOODNESS AGAIN!" Possibly overlaps with HolyBurnsEvil, since the ray of goodness originated from the Goddess of Goodness. HolyBurnsEvil also applies to some vampires in the comic.

* ''WesternAnimation/AmericanDad'': The episode "Frannie 911" reveals that this trope is why Roger is such a {{Jerkass}}. To elaborate, his species has to let out their "bitchiness" on a regular basis, or it will turn to bile and poison them; thus, if Roger acts nice for extended periods of time, it will literally ''kill'' him.
* A minor version from ''[[WesternAnimation/CareBearsAdventuresInCareALot Adventures in Care-a-Lot]]'': after seeing his plan to break up a band made of a few of the female Care Bears thwarted by ThePowerOfFriendship, Grizzle comments, "This sickening display of friendship HURTS!" Trueheart asks if it isn't just the high heels he's wearing as part of his [[DisguisedInDrag drag disguise]].
* Variation: In an episode of the 90s ''WesternAnimation/TheIncredibleHulk'' cartoon, ComicBook/GhostRider realises that Rick is a good kid when his {{hellfire}} doesn't hurt him.
* In one episode of ''WesternAnimation/ThunderCats'', a robot is armed with a magic katana and sent out on a rampage. The katana's original user, a samurai, stops this by doing a BareHandedBladeBlock which results in the robot exploding. The samurai explains that since the machines are neither good nor evil, the katana didn't know it was being misused, but after touching samurai's skin it caught on and destroyed the robot.
* A softer example, Doktor Frogg from ''WesternAnimation/LeagueOfSuperEvil'' is shown to hate good things like rainbows and happiness. When he was sent to a SugarBowl, he acted like he was stuck in the deepest pits of hell.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', [[LivingShadow King Sombra]] feels acute pain when he tries to cross a barrier powered by the IncorruptiblePurePureness of Princess Cadence, to the point that it severs his horn.
* ''WesternAnimation/JackieChanAdventures'': Demon sorcerer Shendu cannot touch the Pan'ku Box without hurting himself, but he needs it [[SealedEvilInACan to release his siblings]]. He tries a variety of methods to take it, such as having his minions grab it (the J-Team distracts them), using a staff to push it (it electrocutes him), and covering his hands with clothes (it works, but the cloth bursts into flame).
** Later on Valmont, the human whose body Shendu is possessing, rebels against him by deliberately grabbing the box, temporarily knocking Shendu out cold.
--->'''Shendu:''' No! We can't touch it, remember!\\
'''Valmont:''' YOU can't! ''(wills his body into grabbing the box)''
* ''WesternAnimation/SamuraiJack'''s god constructed Katana. Any evil that comes in ''contact'' with it is obliterated spectacularly. Its the only thing Aku ''fears'', having been nearly completely destroyed by it and Jack on multiple occasions. Also doesn't help that Jack himself is the embodiment of TheParagon with IncorruptiblePurePureness to back up the sword's strength.
* One story arc in ''WesternAnimation/RockyAndBullwinkle'' involves our heroes fighting an infestation of Pottsylvania Creepers, vicious {{Man Eating Plant}}s that shrug off every attempt to kill them or trim them back. Bullwinkle eventually quips "We've tried everything except kissing those plants goodnight!", and that [[EurekaMoment gives Rocky and idea]]; try being ''nice'' to them. It works like a charm, the Pottsylvania Creepers are so belligerent that [[WeaksauceWeakness kindness causes them to wither and die]].
* [[spoiler:Anti-Pops]] from ''WesternAnimation/RegularShow'' is BroughtDownToNormal when subjected to kindness and sympathy from others, as he's powered by negative emotions and destruction. [[spoiler:Pops exploits this to defeat him by giving him a reassuring hug before [[HeroicSacrifice flying into a nearby star]], gambling that the expression of love would depower Anti-Pops and render him killable.]]
