The Heartless



""All they know is how to hurt and destroy and kill. Admirable when you need someone hurt, destroyed or killed, but what about the times when you just want them to sit down and shut up? Oh, FORGET that.""

- Dark General Cobalt, Sailor Nothing, about the problems with working with Yamiko

The Heartless are different from the average Monster of the Week in that they're basically born out of people's negative emotions, like a poltergeist. They can be a special case of the Body Horror, but can also be a part of the victims Soul Anatomy that has been separated from them, and may not have a physical body at all. This is convenient for the right villain, since it can be an unlimited resource; the Victim of the Week always seems loaded with problems and angst for The Heartless to feed on. It can also have a self-propagating "zombie" effect.

The trouble for the heroes is these are difficult to get rid of, especially if The Heartless still display an awareness of the world (usually, as a ruse of the Enigmatic Minion). If an established character becomes one of The Heartless, they may act as if they had undergone a Face Heel Turn.

The Messiah's power is usually to combat The Heartless, or even to heal them. The Anti Hero or Ineffectual Loner usually insists the victims are too far gone and should be offed before more people get hurt. Occasionally, a victim who is Fighting From the Inside can resist The Heartless' control.

Depending on the context, this trope is a subtrope of Abstract Apotheosis. This is because nearly every series that this trope is used in represent these critters as An Aesop about them being in everyone's hearts. Contrast/See also Made of Evil. Compare The Soulless, characters whose lack of a soul doesn't make them physical monsters... just metaphorical ones.

Obligatory Heart Drive link thrown in for good measure.

Trope Namer

 * The Kingdom Hearts videogames have the Heartless, which fit the definition of this trope. However, they were described as starting out as decidedly less destructive before the series' Big Bad, Xehanort, started his experiments on them.
 * And the Unversed, which are the "opposite of life" are born from raw Darkness. They apparently feed off of negative emotions, in a different way than the Heartless do.
 * There's also Vanitas of Birth By Sleep who  Unversed take this to the next level.

Anime and Manga

 * Sailor Moon's Nephrite eschewed using typical Energy Absorption tactics, preferring to concentrate dark power into a single highly motivated (and increasingly obsessive) person to get the best energy. His predecessor Jadeite worked in a similar way by amplifying negative traits in people, except he worked with large groups of people--Education Mamas, obsessive dieters, etc.--instead of just one person at a time. Zoisite and Kunzite just possessed people.
 * There is also Phages in the final season, and the Lemures of the previous forth. The former are humans without a 'Star Seed' while the latter are appearently people without their dreams (in the anime version).
 * The Big Bad of the entire series, is a God of Evil born from the malice of all living beings called Chaos, and he ends up having his essence scattered into the hearts of everybody across the universe... to defeat it. Chaos also spawned the Big Bads of all the previous four seasons, being lesser Eldritch Abominations compared to Chaos.
 * The monsters  in Magic Knight Rayearth were born out the despair of Cephiro's citizens.
 * The Mazoku "Monster" Race from The Slayers
 * The Invaders of Gate Keepers.
 * The Hollows from Bleach are fallen ghosts who have literally lost their hearts, and just have a hole in their chests, hence the name. The Shinigami 'heal' these creatures by destroying them with their swords, freeing the soul to move on to its final reward, while the Quincy destroy them completely (and believe they are justified, since Hollows attack humans).
 * Later in the series, Hollow are revealed to be thought of along the lines of intelligent beasts, unable to really do other than as their instincts tell them to. Arrancar are different and actually possess sapience as well as more positive emotions, leading to some of them being sympathetic characters, and a few of them even being downright nice. They're still more likely to be evil than good, though.
 * Still later, it was revealed that their heart isn't destroyed, but transformed. Rather than disappearing, the negative feelings in it cause it to become the Hollow's mask, and acts as the source of the Hollow's energy. Perhaps part of the reason an Arrancar is more human is that by destroying their mask a part of their human heart is restored.
 * The Virus from Venus Versus Virus.
 * A repeated, enigmatic symbol -- particularly suggestive shadows -- in the movie version of Revolutionary Girl Utena hints that Anthy is missing her heart. However, in an inversion, it is because she is the victim/captive of a monster, not the monster itself. This (probably deliberately) echoes the line about "a doll without a heart" in the TV series.
 * The Zonder, in the Humongous Mecha series Gao Gai Gar are a variation on this; they don't feed on or arise from negative emotions in general so much as they feed on stress specifically. The forms they take on when they transform into Robeasts typically have something to do with the source of their hosts stress, and destroying them leaves the victim feeling quite mellow.
 * Yatagarasu, is described as residing in the darkness of the human heart in Mai-HiME.
 * The fear of Shonen Bat/Lil' Slugger in Paranoia Agent.
 * Akuma in D Gray Man are souls of the dead who have been bent to the will of the Millennium Earl. Often grieving for a lost loved one the bereaved person calls their soul down into an Akuma at which point the soul of the lost loved one is imprisoned and has no will of its own. The Millennium Earl orders the newly made Akuma to kill the person that made them an Akuma and wear their body. So they're sad and in pain and become increasingly tortured and tormented as the Akuma develops its own personality around them. The main character, Allen Walker, has a special eye that allows him to see these trapped souls, and aims to release them from their pain... which means killing them. The rest of the Exorcists kill them just because they're monsters, and most of them wouldn't understand or take kindly to Allen's sympathy for them. It's not that the Exorcists don't know how the Akuma are made, but rather that they tend to forget, because they're not constantly seeing it.
 * One of Noah claims that if an Akuma self-destructs, rather than freeing the soul, the human soul is destroyed. She then demonstrates this to Allen, who watches in horror as the soul is torn into screaming pieces.
 * More generally, it's stated that the human soul will be released only if the Akuma are killed by an Innocence weapon. Any other method will destroy the soul. It's just that since normal humans don't have a chance in hell of of killing an Akuma in the first place, the question never comes up.
 * Miss Michiko from Dennou Coil, while not technically a monster,.
 * The ending of the Chrono Crusade anime strongly implies that Aion was born from humans' negative emotions and as such, can resurrect himself at will as long as people suffer or hate.
 * Naraku, the Big Bad of Inuyasha, was partly born from a man's cruelty.
 * In King of Thorn, most of the grotesque monsters came to existence as embodiments of the deepest, primal fears of scientists infected with the Medusa virus.
 * At a metaphorical level, Knives in the Trigun manga fulfills the definition too, as he might be viewed as an embodiment of the worst 'sins' of humankind. It is significant that in Trigun Maximum, he starts of as . As such, he fits the Shadow Archetype not only for Vash but also for humans.
 * The Reibi from the second Naruto Shippuden Movie is a demon made from the hate or other dark thoughts of others..
 * The Reibi from the second Naruto Shippuden Movie is a demon made from the hate or other dark thoughts of others..


 * A major reason Naruto had difficulty controlling the Kyuubi was.
 * Also at a metaphorical level, the homunculi from Fullmetal Alchemist may be seen as embodying the 'darkness' or despair in the heart of . Or even of   or humankind itself. Of course, their Theme Naming following the Seven Deadly Sins helps this interpretation. In the manga, they are manifestations of.
 * The X-charas in Shugo Chara can be seen as a form of this: Usually, when a child needs help in fulfilling their dreams, these dreams materialize and become a "Guardian-chara". However, if the child has already GIVEN UP all hope, the dreams instead get corrupted with lack of self-esteem, the feeling of being useless and other negative-emotions and become an "X-chara" instead: A little, black creature, determined to destroy everyone and everything around it with the power of the dream, it was originally supposed to embody. The owner of the X-chara usually falls in a comatose-state, with his or her inner voice mourning about how useless he/she is. Amu usually tries to heal such Charas, by using the powers of the humpty-lock, while others, like Ikuto and Rima (at least in the beginning) prefer to simply destroy them -- turning the owner into a child without any hopes for his/her life.
 * The Big Bad of Digimon Tamers, but once it Not to mention that.
 * In Digimon 02, Dagomon's realm is formed by people's dark desires.
 * The, the God of the Berserk universe, is . Qlippoth creatures are also reflections of humanity's darkest side.
 * In addition, there's.
 * Shikabane in Shikabane Hime are formed when someone dies with regrets or an attachment to this world, which turns them into a monster.
 * The Dark Signers from Yu-Gi-Oh! 5D's are a third this, a third The Corruption and a third The Virus.
 * In the Shaman King manga, Oni, which are dangerous spirits conjured by a shaman's ridiculously strong negative emotions. Namely loneliness.
 * The armor bugs in Letter Bee. They are insects that lost their heart. In fact, you kill them by giving them heart, i.e. shooting them with your Empathic Weapon.
 * The witches of Madoka Magica are embodiments of despair. In the ending

Comic Books

 * In Marvel Comics, this is the Void's relationship to the Sentry.
 * The Martian Manhunter literally expels the Heartless in an issue of his own series (a flashback to his Justice League International days). Then he destroys it with Eye Beams.
 * It's worth noting that his personal Heartless is
 * , technically.
 * Grant Morrison's run on Doom Patrol had one of these as the ultimate baddie -- the Candlemaker, an embodiment of mankind's fears of nuclear annihilation.
 * in Johnny the Homicidal Maniac.
 * The emotional spectrum entities in Green Lantern are creatures born from, and embodying the emotions of sentient beings. Naturally, the ones born from fear, greed and rage are particularly nasty.
 * Despite the whole Zombie Apocalypse motif, this is what the Black Lanterns from Blackest Night really were- the unresolved emotions of the dead given form; they just pretended to be the actual (zombified) person in order to trigger emotions in their victims, which they fed off on. The dead person's real soul was not involved, and if the person had died in peace, they couldn't be duplicated.
 * Nega-Scott in Scott Pilgrim (comics only; the movie version is completely different).
 * The main villain of one Aquaman story arc was "The Thirst", a golem which is animated as the shadow self of the chosen waterbarer should they use their power to harm rather then heal. His only desire is to drink life itself. They take this role to the waterbarer, their strength proportional to the barer's negative emotions. Only after Aquaman finds it in his heart to forgive his archenemy, can he muster the strength to defeat him.

Film

 * In Forbidden Planet, the Monsters from the Id are invisible, invincible, incredibly strong beings of pure vengeance. Their existence is a side effect of the Deadly Upgrade.
 * The Brood is about a woman who literally gives birth to her inner demons.
 * The Nothing in The Neverending Story is the result of children no longer believing in fairy tales.
 * However, in the original book, it's implied to be more a result of increasing cynicism and loss of imagination, as it's spread by.
 * Hard to see how.
 * It's because
 * The book is big on emphasizing the difference between  It also implies that   are themselves the Heartless, being the dark side of creatures from Fantasia.
 * The curse in Ju On was created by a fit of rage.
 * The Pink Slime in Ghostbusters II was generated by the negative emotions of New York. The substance itself is actually neutral, but New York is just that cynical and negative a city.

Literature

 * The Spectres of His Dark Materials.
 * Harry Potter: Dementors are a borderline case. We never learn how they come to be, or, indeed, if anyone knows this at all, but their presence drains the positive emotions of everyone around them, and they will swallow the souls of anyone too weak to fight back if given the chance. The Ministry actually uses them as prison guards, although some (such as Dumbledore), question the wisdom of this approach - with good reason, as they defect to Voldemort almost as soon as he asks, since he doesn't impose any restrictions on them.
 * As are boggarts, whose shape depends on what the person nearest them is most afraid of.
 * The demons in Simon R Green's Darkwood books.
 * The series also does something of an extension on the the trope by having the Infernal Devices (swords) chosen to fight the demon armies capable of burning the humanity right out of the user, in essence making them the same or worse than the things they're fighting.
 * In Neil Gaiman's American Gods, Odin thrives on death and Loki on chaos.
 * The Strange Case of Doctor Jekyll and Mr. Hyde is about how Jekyll tries to chemically rid himself of negative impulses and emotions, but instead leads to his transformation into the embodiment of them.
 * Hyde could be seen as the Ur-example of this trope. Also unmentioned above but relevant to this trope and the quote, the story not only makes much of Hyde's utter lack of any kind of positive emotion or morals, but also points out that because he has none of these things, and hence no limits, he has an unrivaled love for life. It is this addictive sensation that actually draws Jekyll into continuing the experiment until it is absolutely too late to turn back.
 * In the second volume of the League of Extraordinary Gentlemen, Mr. Hyde discusses this with the others; he explains that he's been getting bigger over the years while Jekyll's been wasting away because Jekyll kept all the restraint for himself.
 * The Beast in Lord of the Flies is initially thought to be a physical threat, but eventually we come to understand that it is the darkness of man's heart, and is the corruption of human kind's minds. It should be noted though that the Beast is never actually seen because it's all in the characters' minds.
 * They do, however, mistake other people for the beast, one being a dead airman who has ejected from his aircraft above them and the  and who Golding gives a beautiful burial.
 * In "The Fisherman And His Soul" by Oscar Wilde, a Fisherman cuts his shadow (which holds his soul) free from his body so that he can live in the sea with his love, a mermaid. The soul, lacking a heart, becomes evil.
 * The Serpents in the Death Gate Cycle were created by magic gone mad fused with their creators' fear and hatred- their goal is to turn the universe into "a prison house of suffering and death" because negative emotions give them power and prolong their existence. Unlike a lot of examples they're actually very smart (most of the time), and can take whatever shape they want to further their goals, though they prefer appearing as hideous snakelike creatures in order to best terrify people.
 * The Overlook Hotel in The Shining is depicted as basically being The Heartless in architectural form, if you go by the interpretation that the paranormal side of what's happening in it is genuine.
 * The Shadowen in The Heritage of Shannara are very much this trope: smoky, bodyjacking wraiths made up of people's negative emotions and hatreds.
 * From the same author, the feeders in The Word and The Void are creepy, shadowy beings that feed on negative emotions, and induce them in people to boot. The demons, on the other hand, are closer to The Soulless.
 * The Fearlings in The Guardians of Childhood, shadowy wispy spirits that spread fear into the minds of children by turning their dreams into nightmares and convert them into their ranks if overdosed.
 * The Fearlings in The Guardians of Childhood, shadowy wispy spirits that spread fear into the minds of children by turning their dreams into nightmares and convert them into their ranks if overdosed.

Live Action TV

 * Red Dwarf makes ample use of this trope in many episodes, such as:
 * In one episode, the crew land on a moon that forms itself to mimic the mind of Rimmer, who is... pretty much all the worst traits of humanity. They are trapped, and decide to build up Rimmer's self-esteem in order to escape. This culminates in giving Rimmer a group hug.
 * "Polymorph", which featured a monster which feeds on emotions such as fear, guilt, rage and vanity, and changes its shape in response to each person's inner demon in order to elicit these emotions.
 * Rimmerworld, which is populated entirely by descendants of Rimmer who have weeded out any trace of bravery, kindness or loyalty, in favor of all of Rimmer's worst qualities. They're all named Rimmer.
 * Legion, a "gestalt entity" comprised of the four crew members' combined consciousnesses. They defeat it by
 * The Mara from Doctor Who. It is a parasitic being of pure hate and rage that requires the fear of its victims to survive. As the Doctor learns from a mystic in its second appearance, "fear is the only poison.". When forced to reveal itself, it looks like a rather pathetic giant carnival snake.
 * The Valeyard. The Doctor's worst possible future self, created by the Time Lords to condemn him. In return, he would get the Doctor's body. He's so bad, he terrifies the Master, who once held the universe to ransom.
 * The Dream Lord. More a Master of Illusion and personification of the Doctor's darkness and self hatred than the Valeyard.
 * The Horrors from Garo.
 * In one episode of Amazing Extraordinary Friends, Applied Phlebotinum splits the heroes into separate beings embodying their good and evil sides (although their 'evil' sides are basically selfish more than anything else).
 * The creature Armus from the Star Trek the Next Generation episode Skin of Evil describes himself as having come from a race of Titans who learned to physically manifest the dark part of their natures as a second skin, which they then discarded. Armus is the amalgamation of all of the discarded evil, or potential for evil, of an entire race. To say the least, he's a bit peeved about being left behind.
 * An interesting example in that Armus is defeated by confronting him with that fact that he is less heartless than he first appears.
 * Ultraman 80 had a whole series of monsters created by negative emotional energy that was called "Minus Energy." One of these monsters was an Evil Twin of Ultra Seven.

Tabletop Games

 * Though Word of God says that the Devilbirds are supposed to be Mortasheen's demon-equivalents, they fit equally well under this trope. For those who don't know, they're Boschian bird-monsters each embodying a negative emotion, which feed by inducing said emotions in other people . Let us take the Devilbird of Gluttony for example. It feeds by inducing a hunger so fierce in a bystander that they will eat anything in sight. They then are psychically forced to go back to the Devilbird's nest and vomit up what they've eaten in said Devilbird's mouth. In the advanced stages of this hunger they may become so ravenous that they begin to eat themselves just to fill their hunger. And yes, almost all of the Devilbirds are this horrible. Even the one based on positive emotions turns its victims into hopeless addicts. The only exception is the Devilbird of Sloth, which is so overcome with its negative emotion that it doesn't do anything -- harming and exploiting others or even hatching from its egg are far too much work for a creature that completely slothful.
 * Oh, and by the way, there's actually going to be an area in the upcoming game dominated by these things. Not many details have been released on it by way of Word of God except for the fact that it's "Worse than you can possibly imagine".
 * The Shadows from Wraith: The Oblivion. Each wraith has a nihilistic voice in the back of their head, urging them away from the things that defined them in life and towards oblivion. Wraiths who give in to this voice too deeply become Spectres, agents of Oblivion focused on destroying all existence.
 * However, the reverse is also true: Spectres have a Psyche, the voice of life and hope that tries to talk them into doing 'the right thing'.
 * Werewolf: The Apocalypse also had Bane Spirits, spirits of violence, anger, misery, and corruption used to harrow humans and turn them into fomori and servants for the Wyrm. While the Bane Spirits are born of mankind, the gameline makes it clear that just shoving an anger spirit in someone doesn't make them the Hulk; they need to give into its subtle insinuations first...
 * In Inferno for the New World of Darkness, demons are pretty much the Anthropomorphic Personification of this trope, literally seeming to be created from human evil (although due to their universal Lord of Lies ability, this is nearly impossible to verify). They start off as bodyless, nameless voices called Whisperers, spirits transformed by a combination of human evil and...something, Enemies Without who gained a life beyond that, and the ghosts of the evil. After tempting people to sin or write Testaments for them, they evolve into Dominions, who exist to make themselves more powerful through spreading sin and darkness.
 * Fan-made expansion Genius: The Transgression has an interesting variant in Manes, who represent popular concepts disproved by science. Entire worlds can be created this way -- the moment the Viking probe sent back pictures of Mars as a barren wasteland, the Martian Empire came into existence. They're not always bad though, they just want to continue existing.
 * Additionally, while they're more like normal people than most, the Clockstoppers are pretty much anti-Geniuses; they possess no spark of creativity and reduce wonder and Wonders to emptiness. Did I mention the part where in place of a creative "spark" they possess a gnawing "void" that essentially means they run on spite?
 * In GURPS Fantasy II, the various monsters infesting the Mad Lands not only are often humans corrupted by their dark sides, but their naming even follows the "-less" format. E.g. people who don't speak out when they should become Soundless, people who are too quick to take offense become Skinless, etc.
 * The four gods of Chaos in Warhammer 40000 are born from base emotions. Khorne is the God of Hate, Rage, Blood, War, Honor and Killing. Tzeentch is the God of Change, Hope, Ambition, Manipulation, Scheming and Sorcery. Nurgle is the God of Decay, Despair, Love, Destruction, and Disease. Slaanesh is the God of Decadence, Excess, Pain, Pleasure and Self-Indulgence.
 * The Circles of Hell in Obsidian.
 * In Dungeons and Dragons, there is the Fihyr (from the Monster Manual II.) To quote the description, "Fihyr are the collected fears of humanity made corporeal."
 * The Nightmares from Don't Rest Your Head are things from unfeeling bureaucracy to sleazy journalism to hatred itself given flesh, either by a person transforming into one due to severe insanity, or by more exotic means -- the Ladies in Hating are either trained in the High School or created from young girls poisoned by the blood of other Ladies in Hating, while legend has it that Mother When came from... somewhere else when someone tried to pick the lock on a door out of the Mad City during the Thirteenth Hour. They are almost universally cruel, twisted, and vicious, incapable of mercy, compassion, or kindness... and the very fact that the Wax King doesn't match this description is sometimes taken as proof that he isn't actually a Nightmare at all.
 * Most Deadlands monsters are of this variety. The setting runs on Clap Your Hands If You Believe Fear, and the Big Bads, who are the primary Heartless of this verse, harvest human fear and use it to animate anything the local populace fears, be it jackalopes, wendigos or living blast shadows. These created abominations are powered by fear too, so they are also The Heartless.
 * The Horrors of Earthdawn and Shadowrun are Eldritch Abominations from another dimension that feed on pain and negative emotions. They vary wildly in their intelligence and habits, from near-mindless beasts that slaughter indiscriminately to diabolical masterminds who start wars and plagues. Then there are those like Yserthgrathe and Chantral's Horror, who go for quality over quantity - find a single "perfect" victim and dedicate your existence to inflicting misery on them, including making the immortal so that there is never any escape.
 * Magic the Gathering gives this sort of origin to devils (as having come from demons) on the plane of Innistrad, as described in the flavor text of Riot Devils--"Devils are demons' unearthly desires made flesh."

Video Games
"Mega Man: Living creatures all have both good and evil in their heart. No duh!"
 * Dark Force from Phantasy Star is a variation of this. While the ultimate villain of the series, the Profound Darkness, is locked in another dimension, its hatred is strong enough to break through the seal and take physical form, manifesting as the series's reoccuring nemesis.
 * The Poes from The Legend of Zelda, which are described in Ocarina of Time as spirits of hatred.
 * Also, Dark Link.
 * The spawn of Dark Gaia in Sonic Unleashed are, according the the in-game bestiary, negative emotions which have manifested physically using Dark Gaia's energy. In addition, they'll also possess people at night, completely turning their personalities arounds, usually for the worse.
 * Monster Rancher Evo has these, but it's only apparent on the overworld stand-ins, as during actual battle the enemy monsters looks the same as if you were controlling them.
 * The Fiends from Final Fantasy X are the souls of anyone who died without being purified, either in the lack of regret in their soul in death, or via ritual after.
 * The Aeons on the other hand are the manifestation of the souls in a more positive way. By technicality they still are pretty darn close to the monsters in concept because they chose to become an unsent. However, unlike the monsters, they willingly gave up their bodies to aid the summoners so they retain their humanity.
 * The fiends a particularly tragic example, as unlike most they are not forcibly converted. Rather, they're left in an And I Must Scream state until the combination of their latent emotions and the solitude drives them completely insane.
 * A good many monsters in Final Fantasy XII were also created by powerful negative emotions.
 * And in Final Fantasy IV, Cecil must battle  at the top of Mount Ordeals in order to
 * The monsters in the Silent Hill series.
 * The Gnosis in the Xenosaga trilogy.
 * The Shadows in Persona 3 are essentially this.
 * Persona 4 features Shadows that are literally.
 * In Persona 2, Nyarlathotep is revealed to be
 * In Raidou Kuzunoha vs. the Soulless Army, the Hiruko are what happens when The Heartless gets combined with Body Horror, resulting in a race of parasitic monsters bred from the despair, hate and fear of the residents of the Capital who at the slightest provocation will erupt in a Nightmare Fuel-laden scene, converting the hapless victim into a Red Cape, or outright bursting out of the body. Neither variant is particularly pleasant.
 * The Noise in The World Ends With You follows this trope to a tee. Not only this but they will be drawn to negative emotions and can covertly possess people so that they appear to be "in a rut."
 * This is understandable, since this game was made by the same people who made Kingdom Hearts, and the Noise resemble Heartless with tattoos.
 * in Tales of Innocence formed.
 * Zerom in Tales of Hearts are creatures that feed on life force, causing a wasting disease called Despir Sickness that not only puts the victim into depression, but eventually leaves it a petrified husk. They are apparently drawn to people who are in the grip of negative emotions like fear, doubt, and grief, because people who have had such emotions amplified by MacGuffins invariably come down with a bad case of the disease.
 * Darth Nihilus from KotOR 2 became a living entity of pure hunger when The Dark Side consumed him. His most infamous power is a life drain that can instantly cause the extinction of an entire planet.
 * Darkling from Ghost Master
 * Dark Brain of The Great Battle and later Super Robot Wars, who feeds on negative energy and gets more powerful. He CAN get punched out by the heroes, but they can't kill him, since there's no way they can destroy the negative energies of humanity.
 * To that extension, Destiny's evil group Ruina also feeds on negative energies to make them powerful, doubled that they reside in a Crapsack World where lots of such things exist.
 * It's suggested several times that the power infusing DarkChips in Megaman Battle Network 4 and 5 comes from people's hatred. (It also seems to come from a dark dimension called Murkland, but the two aren't necessarily contradictory.) As usual in these dark/light games, the bad guys are always ranting at you about how everyone is evil deep down, which makes it very satisfying when Mega Man smacks down Duo in the ending of 4:

"Pokedex: "Shuppet grows by feeding on dark emotions, such as vengefulness and envy, in the hearts of people. It roams through cities in search of grudges that taint people.""
 * The original-series antecedent of the above storyline is Mega Man 8's "Evil Energy". Rather than coming from dark thoughts, this stuff feeds on them -- and it finds Wily an excellent source.
 * The demons of the Shadow Hearts universe thrive on and are fueled by the negative emotions and hatred of the world, Malice. One of the perils of being a Harmonixer, one who takes on demonic form to fight against the demons, is that killing them causes Malice to build up in one's soul, as well, risking the destruction of the Harmonixer's mind.
 * The Pokémon Shuppet feeds on the negative emotions of people.


 * In the Pokémon anime, this seems to be a good thing. When a shuppet feeds off someone's dark emotions, they feel a lot better. The Shuppet also means no harm.
 * The Final Boss Devil in Battle Moon Wars is a Giant Space Flea From Nowhere that is the this trope, also apparently any land area that has magic will generate evil spirits that oddly looks like Shout Outs to various anime series.
 * Bogmire in Luigis Mansion. More precisely, as the quote says, it's a manifestation of the fear and despair of the mansion itself: A product of the mansion's fear and despair. He's not sure who to fear or what to despair these days.
 * One of the bosses in Hype the Time Quest is the titular character's dark side, although it is never elaborated upon, and as such may not satisfy the trope fully.
 * Since Psychonauts takes place largely inside people's minds---in particular, the patients of a mental hospital---most enemies in the Mental Worlds are this in some form. Perhaps most explicit are the Nightmares, demonic-looking beasts that appear in Boyd's mind and locked up inside Milla's.
 * The Censors are, in some ways, the opposite of this---they're essentially antibodies of the mind that destroy thoughts that don't belong, such as forms of insanity. Unfortunately, since you don't belong in other people's minds, they consider you fair game.
 * Dracula in the Castlevania series is occasionally described as this; people describe him as the product/manifestation of the collective evil in humankind and our bastardry is what's bringing him back, and as of the Sorrow series, he's described as God's Evil Counterpart who comes back because the balance of nature requires it (or something like that).
 * The Lords of Shadow from Castlevania Lords of Shadow also count. When, the evil they abandoned possessed their mortal bodies and became the Lords of Shadow responsible for so much misery in the world.
 * The "blot" versions of eaten residents of wasteland in the final level of "Epic Mickey"
 * The Ixupi from Shivers are ancient Mayincatec demons that suck away the life essence of any nearby human beings.
 * The Negativitron of Little Big Planet 2 was born of the negative personality aspects of the creators of Craftworld. This is technically a spoiler, but the name alone is kind of a giveaway, and it's foreshadowed to hell and back along the way besides.
 * The enemies in the final chapter of Disgaea 4 a Promise Unforgotten are physical manifestations of the Big Bad's malice, appearing as darkly colored versions of the various generic classes that speak with his voice.
 * In Ultima IX, the Guardian, dimension conquering threat from the previous several games, is retconned into the Avatar's Enemy Without: specifically, the embodiment of all the evil and darkness he cast off when he became the Avatar.
 * The Sha in the upcoming World of Warcraft expansion are said to be physical manifestations of negative energy. For example, fighting on the island of Pandaria releases energy that can form Sha.
 * This is one of many fan theories regarding Wario of the Super Mario Bros universe.
 * The Gohma from Asuras Wrath.

Web Original

 * The Yamiko in the Sailor Nothing novel are a particularly gruesome version, with the interesting twist that their being pure evil also makes them incompetent, with no self-control or self-discipline (see the Quotes page for the full version of the page quote). This may be considered a Deconstruction of sorts.
 * The Yamiko are also interesting in that they're made by magically cloning a human, with the cloning process doing nothing more harmful than knocking out the human. Of course, the first act of a newborn Yamiko is usually to murder the original, but it's possible for the whole and unaltered human to come face to face with the living embodiment of their dark side.

Western Animation

 * Unicron's portrayal in Transformers Armada claims that he feeds on hatred, violence, et cetera. This is inconsistent with many other portrayals of Unicron, however, as usually he feeds on planets.
 * It's a bit more complicated than that. He feeds on planets, but the energy from hatred and violence is what gives him the strength to metaphorically get out of bed in the morning.
 * Penelope Spectra from Danny Phantom was a ghost posing as a school guidance counselor. She made her patients more depressed, however, because she needed their negative emotions to keep herself young.
