->'''Jack Frost''': Afraid? I'm not afraid of you.
->'''Pitch Black''': Maybe not. But you ''are'' afraid of something.
->'''Jack''': You think so?
->'''Pitch''': I ''know'' so! It's the one thing I always know; people's greatest fears.
-->-- ''WesternAnimation/RiseOfTheGuardians''

Basically the power to discover other people's fears. Often necessary for a WhatDoTheyFearEpisode. This power can come in several forms:

* '''Fear Perception:''' The power to know what a person's fears are. For example, one could see a picture in your head or something similar. One then has different options to use this info. This type does not necessarily include the ability to project those fears into people's heads and they may have to be exploited in a more normal way, such as dropping them in a snake pit or a sewer full of rats.
* '''Fear Inducement:''' The power to [[YourWorstNightmare bring a person's fears to life]] without actually having any knowledge about what those fears are. This power does not deliberately cause a person to believe they are, for example, vomiting worms, it's just the effect of the power on that particular person. It is sort of like infecting people with dread.
* '''Fear Invocation:''' The power to see a person's fears and[=/=]or show them their fears (if they have several). Control is near-absolute and often includes intensity and duration. A character with this power will usually have some kind of psychic or illusionary power to bring the fears to life.

It goes without saying that this is usually a [[BadPowersBadPeople bad guy power]]. If it's a power used by a DeadlyDecadentCourt, OmniscientCouncilOfVagueness or just a plain evil enough version of TheGovernment, then it will almost always take the form of {{Room 101}}. It can, however, be used by a TerrorHero who ultimately fights for the good guys -- though, naturally, these tend to be some shade of AntiHero.


[[folder:Anime & Manga]]
* Phoenix Ikki in ''Manga/SaintSeiya'' was initially introduced as a bad guy with the ability to Invoke Fear. What makes his case pretty interesting is that he eventually undergoes a HeelFaceTurn, yet keeps his "Phoenix Illusion Demon Fist", as a form of CoolAndUnusualPunishment, making it sort of a Subversion of BadPowersBadPeople. The technique digs up what will inflict the most damage to your mind, and if you lack willpower, it WILL OneHitKill you. And even if you DO have the willpower to not die from the mental blow, odds are you will end up extremely weakened from the shock and be easy prey. Well, there is ONE instance of an opponent that was able to NOT ONLY shake it off like nothing, but actually inflict it back on him, but we're talking about the one Gold Saint specializing in meditation, peace of mind and [[BadassBoast closest to the Gods]]. Interestingly, this technique even gets EpiphanyTherapy uses in the Asgard arc on two enemies.

[[folder:Comic Books]]
* Dani Moonstar in ''Comicbook/NewMutants'' created illusions based on the target's worst fears, as did ''Comicbook/TeenTitans'' villain Phobia.
* A variation of Fear Inducement appeared in ''Creator/BrianMichaelBendis'' 's ''Comicbook/{{Alias}}''. In Volume Four, Jessica comes face-to-face with occasional ''Comicbook/{{Daredevil}}'' villain (and Jessica's archenemy) The Purple Man, whose body secretes chemical pheromones which, when inhaled or absorbed through the skin, allow him to control their actions by verbal suggestions. (The Purple Man, like ''ComicBook/TheJoker'', is aware that he exists in a comic book). He orders Jessica to imagine the most horrifying thing she can envision, which turns out to be the corpse of her boyfriend (Antman II) covered in ants lying in her bed. The Purple Man comments that he wonders what she is seeing, guesses "it doesn't work that way."
* In ''Franchise/{{Batman}}'', "The Scarecrow" uses a hallucination-inducing gas to discover and induce a person's greatest fear. (Ironically, poetic justice proves his ''own'' greatest fear turns out to be-- a fear of BATS!)
** This seems to be a major theme in ''Film/TheDarkKnightSaga'', especially in the first part, ''Film/BatmanBegins''.
** Another Batman villain, Cornelius Stirk, wanders into this territory as well. He's a telepath who can make other people see what he wants, which he uses to both make himself appear as someone they trust, and to prey on their fears.
* Trauma of ''[[Comicbook/AvengersTheInitiative Avengers: Initiative]]'' actually transforms into what his target fears, giving him whatever physical attributes and/or powers that go along with the new form. This combination of psychic powers and shapeshifting was considered a "holy grail" of mutant powers by [[{{Jerkass}} Gyrich]]. [[spoiler: Also, he's not really a mutant at all, but the [[HalfHumanHybrid half-human]] son of the dream demon Nightmare.]]
** It should be noted that this is imperfect--he went through four forms trying to find a weakness in TheIncredibleHulk (who, as it turns out, isn't afraid of anything), and got tossed into a parked car for his troubles.
* ''Comicbook/{{Gen 13}}'' villain Phobia was a creepy little girl with Fear Invocation powers.
* The Sinestro Corps of the Franchise/GreenLantern comics is based entirely on this concept. With their power rings they can create constructs of both their own fears and their victims'.
* The Nightmare spirits from IDW's ''[[ComicBook/MyLittlePonyFriendshipIsMagicIDW My Little Pony: Friendship is Magic]]'' comic inflict this upon our heroes when they try to rescue Rarity from their clutches. With ThePowerOfFriendship, Twilight Sparkle faces her fear of disappointing Princess Celestia and being dismissed as her student, Rainbow Dash her fear of losing the power of flight, Pinkie Pie her fear of being unable to make others happy, Fluttershy her fear of losing her way with animals, and Applejack her fear of letting down her family.
* In ComicBook/PaperinikNewAdventures [[SuperSoldier Trauma]] was a Fear Inducer, creating fear in his enemy and then [[EmotionEater eating it]] to transform the victims in the mindless [[SlaveMook Coolflames]]. In the sequel, [=PK2=], we have Korinna, a Fear Invoker who uses her power to create a small army convinced she is the only one capable of stopping the things they are afraid of.
* A comic based on ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'' depicted the old toyline villain Scare-Glow as having Fear Invocation powers. He psychically discerns a person's greatest fear before trapping them in an illusion based on it. Apparently, it's harder to figure out what certain people are afraid of, but he thinks that if he waits long enough he'll discover what even ''Skeletor'' fears, knowledge he can then use to free himself from Skeletor's service.
* ''ComicBook/JudgeDredd'': Judge Fear, the cape-wearing and helmeted [[EvilCounterpart Dark Judge]], has the ability to discern any person's deepest fear so he can literally scare them to death by opening his visor and forcing his victims to gaze into his NightmareFace.
** [[http://smg.photobucket.com/user/bobmitchell/media/blog%20pics/FNF-Fist03Big.jpg.html Doesn't work too well]] on Dredd himself though...
-->'''Judge Fear''': [[AC: Gaze into the face of Fear!]]\\
'''Judge Dredd''': [[TalkToTheFist Gaze into the fist of Dredd!]]

[[folder:Fan Works]]
* ''FanFic/RhymeAndReason'': [[BigBad Ivana M. Killjoy]] has done quite some in-depth research on the Rangers as part of her BatmanGambit, including their individual fears which she uses against them somewhat less in Chip's case because she keeps him busy otherwise.
* Naruto in ''[[https://www.fanfiction.net/s/11729865/5/Desperation-Attracts-Vultures Desperation Attracts Vultures]]'' utilizes this against Sasuke at Mei's suggestion (though he takes it much further than she expected). During their match, he first gives Zabuza's "eight targets" speech then disguises himself as Haku and claiming to have never really died. This drives Sasuke into such a panic that he uses both his Cursed Seal and Chidori.
* In [[https://www.mediaminer.org/fanfic/s/legend-of-zelda-fan-fiction/the-legend-of-link-lucky-number-13/19769 The Legend of Link: Lucky Number 13]], [[spoiler:Link]] after becoming the God of Fear instinctively knows what everyone is afraid of (and is fully capable of subjecting them to it).
* In ''Fanfic/TheParselmouthOfGryffindor'', Maximilian, owing to his Boggart nature, can see even an Occlumens's worst fear. Because he's a nice guy all around, he usually keeps it a secret.

[[folder:Films -- Animated]]
* ''WesternAnimation/RiseOfTheGuardians'': Pitch Black has this power- being the Nightmare King and the original Boogeyman, this is only expected.
* ''WesternAnimation/WereBackADinosaursStory'': Professor Screw-Eye has invented a radio that allows him to know what scares people. He uses this radio to his advantage to make his circus of fear (which entertains people by scaring them) successful, and it's also behind his villainous plot to brainwash the educated dinosaurs into ferocious monsters, since lots of people are afraid of dinosaurs.

[[folder:Films -- Live-Action]]
* ''Film/{{Poltergeist}}''. According to their psychic medium consultant, the ghost causing the Freelings all the trouble has this ability.
-->'''Tangina''': Now clear your minds. It knows what scares you. It has from the very beginning. Don't give it any help. It knows too much already.
* Among Shang Tsung's powers in ''Film/MortalKombat'' is the ability to see into a person's soul and find out what that person fears most so he can use that fear against them.
* Freddy Krueger from the ''Franchise/ANightmareOnElmStreet'' franchise attacks people in their nightmares with their fears.
* In the 2003 ''Film/PeterPan'' Hook taunts Peter with his fear of Wendy growing up and forgetting him to throw him off-balance in a battle.
** In the earlier iteration of the Peter Pan mythos, {{Hook}}, Peter, and the Lost Boys capitalize on Hook's fear of ticking clocks (and the Croc who made such noises) to encircle him with clocks, driving him briefly into a panic during the final duel.
---> '''Peter'':' Tick Tock, Tick Tock, Hook's afraid of an old dead croc...
* Pennywise in ''Film/It2017'' seems to be able to detect his victim's major phobias and fears and represent them to feed on them.

* The Feasters from the fantasy book series ''Literature/LadyOfGems'' can [[YourWorstNightmare bring a person's fears to life]] so they can [[EmotionEater feed off that or those persons fears]]
* ''Literature/HarryPotter'': Boggarts take the form of a person's greatest fear, [[RequiredSecondaryPowers which means they have this power]].
* ''Literature/TheDresdenFiles'':
** Since a phobophages' intended victim is at a horror movie convention, this results in {{Captain Ersatz}}en and {{Shout Out}}s aplenty.
** Certain demons and other nasties have a variation: they instinctually know how to cause pain to their victims, but only as information, not as understanding. For instance, a demon knows to attack a family man through his children, but not ''why''.
* In the ''Literature/{{Belgariad}}''[='s=] prequels, Polgara's MindRape persuasion method is revealed to be this. It only failed once, because the target was on drugs (note that if she put much effort into it, she probably could have un-drugged him like Belgarath did in the prequel).
* In ''Literature/NineteenEightyFour'', the Party performs sadistic research on individuals and operates a "Ministry of Love" dedicated to customizing its tortures to suit the individual being tortured. This culminates in the individual's visit to Room101 where their worst fear has been crystallized into reality to make them bend to the party line forever.
* ''Literature/TheWardstoneChronicles'' includes a secondary character with the ability to do something called the Dread, which is a induces fear in its target.
* The ''Literature/BooksOfBayern'' include several characters, mostly antagonists, who are capable of knowing exactly what one fears (mainly things like public humiliation or loss of control, which are the things behind fears like acrophobia or arachnophobia) and also what a person wants, desires, or intends. Their power also gives them the ability to know precisely what to say in order to get what they want. Yeah. It's really no wonder they're mostly Bad Guys.
* The third book of ''Literature/{{Midnighters}}'' has a peculiar scene where [[spoiler:Rex]], the group's HalfHumanHybrid, attempts to intimidate a minor character. He somehow knows (without knowing how he knows) that said character is afraid of snakes, and his appearance and posture ''shift'' in just such a manner as to bring up thoughts of snakes, without changing blatantly enough to be obvious ShapeShifting.
* Amanda Reese of the ''Literature/{{Fingerprints}}'' series was capable of perceiving others' fears.
* Elva from the ''Literature/InheritanceCycle'' is a heroic ([[AntiHero kind of]]) example. She has the ability to sense a person's negative emotions, including fear.
* The Furies in the Franchise/StarTrek quadrilogy of the same name have this as their main weapon: a directed-energy beam that forces anyone who is hit by it to experience sheer terror.
* The titular Machine of ''Literature/GalaxyOfFear: The Nightmare Machine'' is capable of invoking fears in other characters, though some characters note with alarm that machines shouldn't be able to know what those specific fears are. [[spoiler: It's not a machine.]] The fears are amazingly powerful hallucinations, though not always internally consistent, and subject to YearInsideHourOutside. [[spoiler: Eppon]] in ''Army of Terror'' also has this ability.
* The ''{{Literature/Doom}}'' spidermind can retrieve a human's fears from their mind and project horrible images to them.
* The ''Literature/{{Lensman}}'' series offers an unusual example of the ''good guys'' having and using this capability. In all cases it's used against people who have led straight-out revolting, disgusting, criminal and evil lives, in essence letting them be judged by their own consciences, and in all cases but one it is ''lethal''. Justified in-universe in that [[spoiler: the lethal uses are in the context of an ignored warning not to re-enter Arisian space and against a murderer who would have been executed in any case. The third is as an exercise in the true nature of mercy - or otherwise.]]
* ''Literature/JourneyToChaos'': Dengel protected his final lair with a "Fear Field", an array of magic runes that encompass anyone who approaches with an illusion of their worst fear. During ''Literature/LoomingShadow'', all the members of Team Four are subjected to it as they climb Mt. Daci. Basilard sees [[spoiler: his students dying and joining his previous students in blaming him for their death while his EvilUncle kills him with his own sword.]] Nolien sees [[spoiler: his younger brother become an EvilOverlord as First Duke of Heleti, abandon their parents, and abuse Tiza]]. Tiza sees [[spoiler: herself back in the place that caused her amnesia, her friends and mentors dead, and Nolien brainwashed into hating her.]] Guest star party member Zettai sees [[spoiler: her abusive parents come back from the dead and kill her new friends]]. Eric sees [[spoiler: Nulso take over Ataidar and turn Annala into a SexSlave.]]
* In ''Literature/TheTaking'', the invaders besieging the town inherently know what people's fears and insecurities are and use them to drive people to despair [[spoiler:so that they will be of no help to the world's children and thus have their souls taken]]. For Molly, this takes the form of poems she likes being mockingly quoted at her out of nowhere and encounters with her AxCrazy father, whom she fears most.

[[folder:Live Action TV]]
* An episode of ''Series/AreYouAfraidOfTheDark'' entitled "The Tale of the Dangerous Soup" features a restaurant owner making soup out of the fear that is extracted by a magical statue.
* Barbas, the Demon of Fear in ''Series/{{Charmed}}'', is a Fear Perceiver. Played by Billy Drago (John Bly from ''Series/TheAdventuresOfBriscoCountyJr'').
** He [[RecurringCharacter made several appearances throughout the duration of the show]], becoming important enough to have a GoodCounterpart shown in the MirrorUniverse episode. The sheer contrast between the personalities and actions of the two is rather hilarious.
* ''Series/StarTrekTheOriginalSeries'' episode "And The Children Shall Lead". Gorgon the Friendly Angel taught the children the power of learning another person's fears and using the fears to disable and control them. The kids caused Sulu to see swords surrounding the Enterprise so he wouldn't change course and used Uhura's fear of dying to prevent her from calling Starfleet Command.
* ''Series/DoctorWho'':
** The alien monster in the story ''The Mind of Evil'' attacked people with hallucinations of their worst fear.
** Similarly, the hotel in the ''God Complex'', with the added twist that [[spoiler: the ''fear'' is a trap to draw out their ''faith'']]
** The episode ''Frontier in Space'' has the Master using a "hypnosound" to induce the worst fear. Humans see the alien Draconians, while the Draconians see humans. Jo Grant sees a monster from one of her past adventures.
* In the ''Series/{{Haven}}'' episode "Fear and Loathing", Jackie Clark's Trouble is that anyone who looks into her eyes sees their greatest fears instead of her. She has no control over it and hates it. Her ability gets stolen by [[PowerParasite Ian Haskell]] twice.
* In ''Series/{{Hornblower}}'', Jack Simpson finds out that Horatio Hornblower is afraid of heights. Simpson sends his men to tell Hornblower that he's ordered by Lt. Eccleston to climb to the fighting top. It's a lie, nobody gave that order, and Simpson laughs at Hornblower and refuses to help him when he's stuck in the rigging, unable to move.
* ''Series/TheXFiles'':
** Episode "Blood" dealt with people whose phobias were heightened to unbearable levels because they were exposed to drug called LSD-M and they were possibly receiving subliminal messages. (Or they might have been hallucinating them.) The fears included {{Claustrophobia}}, fear of being raped and [[AfraidOfBlood fear of blood]].
** "Wetwired": Government controlled people through SubliminalSeduction transferred through TV broadcasting and caused them very vivid {{Hallucinations}} of their worst fears which compelled them to murder even their loved ones. Scully thought that Mulder is collaborating with TheConspiracy and he helped them to abduct her.
** In "X-Cops", the monster of the week could sense people's worst fear and made them real. Some were literal monsters (a wasp man or a generic villainous killer). A man panicked because he thought his partner is going to leave him. One woman died of exotic disease simply because Scully happened to mention its name.
* This is the Jabberwocky's power in ''Series/OnceUponATimeInWonderland''.
* In an episode of ''Series/WalkerTexasRanger'', a drug lord has just learned that his girlfriend is actually an undercover FBI agent. Knowing that she was afraid of water and couldn't swim, he ordered his henchmen to drown her. Luckily, Walker and company showed up in time to save her.

[[folder:Tabletop Games]]
* The ''TabletopGame/DungeonsAndDragons'' arcane spells [[http://www.d20srd.org/srd/spells/phantasmalkiller.htm Phantasmal Killer]] and [[http://www.d20srd.org/srd/spells/weird.htm Weird]] are Fear Inducers, as they do not require knowledge of their victim's worst fear in order for them to work.
** ''Warriors of Heaven'' has a nonlethal version of the first, 'Phantasmal Terror'. 'A Guide to the Ethereal Plane' introduces the unfortunate result of 'Phantasmal Killer' turning real, as illusions sometimes do there -- Fær, the monster who polymorphs into the victim's nightmare and kills by touch, but isn't resisted as easily as the original spell (it ''is'' for real this time).
** The Dream Larva is the [[EldritchAbomination manifestation of a god's nightmare]], with the ability to shape itself into anyone's greatest fear.
* In ''TabletopGame/ChangelingTheLost'' the first "clause" (read: skill) of the fleeting autumn contract allows a changeling to do this.
* In TabletopGame/InNomine, Calabim that serve the Demon Princess of Nightmares can see a person's worst fear.
* In ''MagicTheGathering'' the black mist that exudes from the empty space where the top half of the planeswalker Ashiok's head used to be enhances Ashiok's ability to see the worst nightmare's of anyone it touches, and bring them to life.

[[folder:Video Games]]
* Some of the ghosts from ''VideoGame/GhostMaster'' have the power to discover peoples unconscious or conscious fears. Often it's up to other ghosts to exploit those fears.
* In ''VideoGame/TheLegendOfSpyro: Eternal Night'', the final test to meet the Chronicler is to face the thing you fear the most. In Spyro's case, [[spoiler: Cynder's evil adult form, as he was afraid of her being turned back into it.]]
** Cynder's Fear element in ''Dawn of the Dragon'' allows her to paralyze opponents with fear, either by letting out a [[MakeMeWannaShout sonic scream]] or blasting them with red energy spheres. Either way, the fear infecting is a secondary effect alongside damage.
* Darth Phobos from ''Franchise/StarWars: VideoGame/TheForceUnleashed'' can use The Force to probe someone's mind to find their fears and create illusions of it. In her boss battle, she puts on a ShapeShifterGuiltTrip, as Starkiller's greatest fear is Juno Eclipse's death.
* Tatari from ''[[VisualNovel/{{Tsukihime}} Melty Blood]]'' is a [[OurVampiresAreDifferent vampire that is repeatedly created from rumors]], and has the ability to [[RealityWarper manifest people's subconscious fears as reality]].
* Wizeman from ''VideoGame/NightsIntoDreams'', being the god and creator of nightmares, is implied to have this power. He can also alter the dreams of visitors or create nightmares in order to take advantage of these fears. He even uses it in the second game to steal Helen's red idea by removing all light from her dream (Helen is deathly afraid of the dark).
* In the ''VideoGame/{{Touhou}}'' game ''Subterranean Animism'', the mind reader Satori Komeiji uses this as her main combat tactic. Her first spellcard is a form of hypnosis that draws past traumas to the surface, which Satori then reads and copies with her subsequent spellcards.
* Parodied in the final level of ''VideoGame/SuperPaperMario''. You are asked what are your worst fears, and then have to go through rooms that contain these, but savvy players can select healing items as answers, causing them to appear. You can also say that Francis (a nerdy chameleon you fought earlier in the game) is your worst fear, causing him to be brought to you and angering him about being interrupted.
* True to form, Scarecrow in ''VideoGame/Injustice2.'' It's a rare intro dialogue when he doesn't tell his opponent what they fear, to say nothing of how he's always fighting in a cloud of fear gas.
* During the quest "Here Lies the Abyss" in ''VideoGame/DragonAgeInquisition'', the Inquisitor and their party are [[spoiler:transported to the Fade (a place most people can only visit in their dreams)]] and must confront a character who can manifest their greatest fears in front of them. Each companion may comment about what it is they see; Cassandra sees maggots, for example, while for the Inquisitor it's spiders.

[[folder: VisualNovels]]
* The King in ''VisualNovel/HatofulBoyfriend Holiday Star'' [[spoiler: is capable of this and uses it to try and drive visitors over the DespairEventHorizon. If he can take away their desire to leave and face the real world and the real problems in their lives [[AssimilationPlot they can stay with him]] and [[GettingSmiliesPaintedOnYourSoul be happy]]. Mostly he talks to them and gives them picture books with simple stories about allegories of themselves inevitably failing and dying, but he also tries to guilt trip Yuuya by talking about what he did and conjuring broken eggs.]]

[[folder:Web Comics]]
* [[Webcomic/WalkyVerse The Head Alien]] has a list of his enemies' fears and tries using it on Joe. However, since he mostly focuses on Joyce and Walky, his list isn't really up to date.
* In ''Webcomic/CaptainSNES'', [[VideoGame/{{Lufia}} Daos]], as Sinistral of Fear, has this ability. Alex successfully bluffs Daos by challenging Daos to name his worst fear, and after trying to do just that, Daos believes Alex has a powerful mental shield, since all Daos saw was a blinking smiley face. (Actually [[VideoGame/{{Berzerk}} Evil Otto]], an entity that genuinely terrifies Alex.)

[[folder:Web Original]]
* Wiki/SCPFoundation:
** [[http://scp-wiki.wikidot.com/scp-825 SCP-825]] is a helmet that has this effect on its wearers, presenting them with increasingly horrific visions based on their worst fears.
** [[http://www.scp-wiki.net/scp-2006 SCP-2006]] is a shape-shifter with the power to transform into what it thinks a person fears. The Foundation's containment procedures make sure that the entity believes that cheesy sci-fi horror movie monsters are the things humanity fears the most. It's classified as "Keter" because its limitless shape-shifting potential means that it could cause TheEndOfTheWorldAsWeKnowIt if it ever escaped and discovered what really scares people. A nuclear holocaust, for example.

[[folder:Western Animation]]
* An episode of ''WesternAnimation/DuckTales1987'' features Magica [=DeSpell=] casting a fear cloud over the [=McDuck=] mansion which causes the inhabitants to experience what they fear most.
* The Fear creature from ''WesternAnimation/ExtremeGhostbusters''.
* In ''WesternAnimation/LiloAndStitchTheSeries'', Experiment 300 (Spooky) has the ability to determine and mimic a person's greatest fear. In the episode in which it appears, it mimics a whole roomful of water and nearly drowns Stitch (Stitch is afraid of water because he can't float in it), and then mimics Nani's fear of having Lilo taken away by mimicking the social worker Cobra Bubbles. Jumba claims that Experiment 300's impression of his ex-wife is ''very'' scary.
* The Shadow of Fear from ''WesternAnimation/XiaolinShowdown'' uses a combination of Perception and Inducement. In order to know what a person fears, one has to use its first power to literally enter someone else's mind; the person using the Shadow of Fear also has some serious reality warping abilities in this state. Once a person has delved into victim's mind long enough to know what they fear, a person can then later use that knowledge to bring their fears to life in the real world.
* The Gremloblin from the ''WesternAnimation/GravityFalls'' episode "Boss Mabel" is a Fear Inducer; anyone who looks into its eyes will be confronted by a vision of their worst fear. Unfortunately for the Gremloblin, Dipper manages to use a mirror to [[HoistByHisOwnPetard subject it to its own fear-gaze]] [[note]]"You've become your own father!"[[/note]].
* The Bloodwolf from ''WesternAnimation/TheAdventuresOfPussInBoots'' describes himself as the source of all fear, and inflicts visions of the heroes' deepest fears to feed on their terror and increase his power.
