->''"The beast devours magic and all things magical.''"
-->-- '''Mozenrath''' on the Thirdac, ''WesternAnimation/AladdinTheSeries''

The Magic Eater is ExactlyWhatItSaysOnTheTin: a character that feeds on magic and/or magic users. If the main character(s) use magic, then the Magic Eater will present a clear threat to them. If PureMagicBeing exists, the Magic Eater may try to prey on them.

Often, eating magic allows them to [[AntiMagic nullify spells]] or [[PowerCopying use them themselves]]. In some cases, a Magic Eater will from simply eating magical energies to being a full MageHuntingMonster. See also PhlebotinumMuncher, especially when it's Munching a SciFi element rather than magic. Overlap with FantasticVermin is common, especially when magic-eating creatures are common and relatively weak individually, making them more of an irritating nuisance than a true threat.

Subtrope of AbstractEater and, through that, of FantasticDietRequirement. See also ManaDrain.

!!Examples of this trope include:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/BlackClover'': This is the true form of [[spoiler:Charmy Pappitson]], after awakening [[spoiler:her [[HalfHumanHybrid half-dwarf]] heritage]] and Food Magic. In this form, [[spoiler:her sheep familiar]] transforms into a wolf that can quite literally eat any magic in the area and transform its mana into SuperStrength for [[spoiler:Charmy]]'s own body.
* ''Manga/FairyTail'' has [[spoiler: Acnologia]] one of the most dangerous beings in the setting. [[spoiler: Acnologia is a Dragon Slayer, a wizard who can empower themselves by eating a certain element. Acnologia's "element" is magic, which makes him all-powerful in a setting where society has built itself upon magic and its use.]]
* ''Anime/LittleWitchAcademia2013'': The Briton Red Dragon is shown to be this, as it grows in strength and power by absorbing any kind of magic, which becomes a problem after a bunch of students attempt to attack the dragon by using magic after it escaped, not realizing that they're only powering it up until it was too late. The only magic that is shown to be effective against the beast is the Shiny Rod's magic, which is how Akko was able to defeat it.
[[/folder]]

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering'': The [[https://scryfall.com/card/ala/138/manaplasm Manaplasm]] is a BlobMonster that feeds on spells; mechanically, it gets a power and toughness boost when its controller casts a spell equal to that spell's mana cost.
-->''Urak froze when he heard it. That was his first mistake. He turned and cast a dramatic ward spell. That was his last.''
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/BuffyTheVampireSlayer'' Season Nine: BigBad Severin is the prophecized Siphon, able to drain magical energy from anything he touches, vampire, demon, and Slayer alike, either [[BroughtDownToNormal bringing them down to normal]] or killing them outright.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/LikeFatherLikeDaughter'': A type of lizard found in Hekapoo's dimension can absorb magic to grow larger, and seems to prefer magical creatures as prey.
* ''Fanfic/NaturalHistories'': The oaks that grew over the ruins of Everfree learned to consume the magic that permeated the ruins of the old Equestrian capital, absorbing it and making themselves strong. It allowed them to overwhelm the other trees of the forest but also changed them, turning them dark and twisted and causing the forest to become the wild, haunted and terrible Everfree Forest of canon.
* ''Fanfic/SurvivalIsATalent'': House elves used to subsist on ambient magic in the environment, but now that there are fewer magical forests in existence they survive by binding themselves to magically powerful families. They are being paid, in a way, though the system is far from ideal for either half of the arrangement; house elves are vulnerable to abuse by their masters, and wizards cannot use their own magic to protect themselves should a house elf turn on them.
[[/folder]]

[[folder:Literature]]
* ''Literature/TheAvatarChronicles'': In ''Epic'', Ragnok owns a shield holding a magic-eating demon that consumes the enchantments of any weapon it touches.
* ''Literature/TheCosmere'': There are a number of types of being that eat Investiture, the generic term for magical power across the worlds.
** ''Literature/{{Elantris}}'': Elantrians are humans who have undergone a supernatural {{Metamorphosis}} that grants them [[TheAgeless agelessness]], GeometricMagic, and the ability to consume investiture instead of food. They ordinarily draw it from their homeland's BackgroundMagicField, but need to bring reserves along if they travel offworld.
** The [[OurSpiritsAreDifferent spirits]] of objects in the [[SpiritWorld Cognitive Realm]] need a source of investiture to sustain themselves when they're travelling far from their physical bodies.
** ''Literature/{{Warbreaker}}'': The Returned are [[CameBackStrong sent back from death]] with idealized bodies and supernatural abilities, but need to consume investiture every week to survive. This poses a bit of a problem, since the only local source is part of the AnatomyOfTheSoul. [[spoiler:One Returned ends up on ''Literature/TheStormlightArchive''[='s=] planet Roshar instead, where investiture literally rains from the sky.]]
** ''Literature/TheStormlightArchive'': Larkins are fantastically rare but otherwise unremarkable crustaceans that feeds on stormlight, which they can suck out of the gems used to store it, Shardplate PoweredArmor, or surgebinders who use the stormlight to fuel their magic -- which can be a nasty surprise for the surgebinder.
* ''Literature/CounselorsAndKings'': The laraken is a demonic monster which consumes any magical energy in its vicinity, making it impossible to defeat through magical means -- and as it lives in TheMagocracy of Halruaa, whose people almost never ''consider'' doing something without magic, it's fed quite well on the countless foolhardy adventurers who've thrown themselves at it over the centuries. It's ultimately revealed to [[spoiler:have been a creation of the legendary necromancer Akhlaur, who can drain stolen magic out of the laraken and use it to refuel his own powers at will -- leaving the creature in a near perpetual state of starvation no matter how much it gorges itself. Akhlaur himself, of course, is immune to the laraken's powers]].
* ''Literature/EnchantedForestChronicles'': Discussed and averted. In ''Searching For Dragons'', someone destroys a large section of the Enchanted Forest, and [[OrgyOfEvidence left a few dragon scales at the scene to implicate the dragons]]. King Mendanbar notes that the [[BackgroundMagicField ambient magic]] in the area is also gone, and wonders if dragons eat magic. Some research shows they don't, proving the dragons weren't responsible. It turns out [[spoiler:the wizards, using magic-absorbing staves, are the cause]].
* ''Literature/GuardsGuards'': Noble dragons, in order to sustain their impossible natures, live on magic -- how else can such a creature even fly, or breathe fire without scorching off its own lips, or breathe fire at all? They were common when magic was as well, but then [[TheMagicGoesAway the magic went away]] and so did they. The cultists originally summon for brief periods though the magic of small enchanted objects, which crumble into ash once depleted, but the beast secures a more solid foothold in reality by absorbing magic from the library of the Unseen University of the wizards.
-->'''Lady Sybil''': But it looks real enough. I mean, you'd expect a magical creature to be, well, gauzy.\\
'''Vimes''': Oh, it's real. It's real all right. But supposing it needs magic like we need... sunlight? Or food?\\
'''Lady Sybil''': It's a thaumivore, you mean?\\
'''Vimes''': [[ExpospeakGag I just think it eats magic, that's all]].
* ''Literature/HeraldsOfValdemar'': the third book of the Mage Wars Trilogy, '''The Silver Gryphon''', introduces a mutant strain of creatures called Wyrsa. Though smaller than their base line cousins, they're far more cooperative and, as Tadrith and Silverblade discover, eat magic. This is a particularly big problem for Tad as gryphons are magical in nature and require it for their bodily functions, especially since a large enough wyrsa pack only has to be in the general area to leech magic (as shown when the duo's magical fire starter and tent both fail). Even the arrival of Skandrannon and Amberdrake only serve to whet the creatures' appetites and Amberdrake points out that if the mutants aren't dealt with now, no magical creature will be safe. Fortunately the pack's voraciousness is used against them by planting magic bait under a rock slide and killing them all.
* ''Literature/MoongobbleAndMe'': Book 5 features the Dangly-Boo, which eats magic. Fortunately for Snelly the Mischief Monster, it also eats half the magic that cursed her to look like a beautiful woman, causing her to turn mostly back to normal. Later, after he's feeling better, he eats the rest of the curse, restoring her to normal. Later, he eats the were-toad curse off the Old Woman of the Forest of Night, achieving what she wanted all along (though not in the ''way'' she intended). After the book's quest is dealt with, it comes back home with Moongobble to help him with his spells -- he'll cast one, it'll eat the spell, and then suggest ways to improve it.
* ''Literature/RiversOfLondon'': [[OurGhostsAreDifferent Ghosts]] feed on magic, becoming more solid and apparently feeling better when they're near a source of it. In ''The Furthest Station'', Peter and Nightingale fill a stone with magic which acts as a sort of ghostly soup kitchen, and the spirits are described as streching their arms to it as though warming them on a fire. It's also been suggested that {{Life Drinker}}s may actually be eating magic, since they're ''kind of'' the same thing.
* ''Literature/TheScholomance'': "Mals" are a hugely varied class of monster that [[MadeOfMagic form out of magic]] and are [[MagicIsAMonsterMagnet drawn to wizards]] to consume their {{Mana}} -- usually along with their flesh.
* ''Literature/TalesFromVerania'': The main villain of the second, third, and fourth books has the ability to consume a wizard's magic, a feat that kills the victim and is akin to devouring someone's life force.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/KamenRiderWizard'': Kamen Rider Beast [[BondCreatures draws his power from the Chimera Phantom]] sealed inside his TransformationTrinket, and will die unless he keeps it fed on the {{Mana}} of Phantoms he defeats. Whereas Wizard's catchphrase when entering battle is "It's Show Time!", Beast's is "It's Lunch Time!". While this makes Beast less powerful than spellcasters with their own mana like Wizard, late in the series it allows him to act as a SpannerInTheWorks: [[spoiler:Since [[BigBad Wiseman]] can't use Beast as a mana battery for his RitualMagic, he captures the other wizards but simply beats up Beast and leaves him to die. Beast then ''[[HeroicSacrifice shatters]]'' his TransformationTrinket, freeing Chimera who proceeds to eat Wiseman's spell before it's complete.]]
** The {{Crossover}} movie ''Film/KamenRiderXKamenRiderGaimAndWizardTheFatefulSengokuMovieBattle'' shows that Chimera is also capable of surviving on [[Series/KamenRiderGaim Helheim Fruit]] (which as parts of a BotanicalAbomination that warps [[SpaceMaster space]] and [[TimeMaster time]] might as well be magic).
* ''Series/MahouSentaiMagiranger''/''Series/PowerRangersMysticForce'': The BigBad [[{{Cthulhumanoid}} N Ma/Octomus the Master]] is capable of eating magic, making him a fitting threat for a mystical setting where magic is the source of the Rangers' powers. The heroes manage to defeat him [[GoingToGiveItMoreEnergy by firing an endless beam of magic down his throat, it being too much for his evil appetite]].
-->'''Octomus:''' I have... devoured... all... ''I CAN!'' (''[[DefeatEqualsExplosion Explodes into nothing]]'')
* ''Series/WizardsVsAliens'': The Nekross have devoured the magic from the rest of the universe, and are now on Earth to finish the job. And, of course, they'll just suck up any spells that you try and throw at them.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** [[{{Oculothorax}} Beholders]], as explained in the ''Lords of Madness'' supplement, are a downplayed example of this trope. Each beholder has specialized "evocularies" in its central eye connected to "dweomerlobes" in its brain, which power its eye-stalks' spell-like abilities by absorbing magic by viewing it through its main eye (the same one that can generate a cone of AntiMagic). The actual magic drained from looking at something like a scroll or wand is minuscule, and it would take extended viewing to drain the item to uselessness, but beholders get more benefit from examining new and different magic items. Which handily explains why a creature with no limbs would have ''bracers of archery'' and ''winged boots'' in its treasure hoard
** The 4th edition added upgraded versions of rust monsters, known as Dweomer Eaters, which eat magic items rather than just metal items.
** Gauths, a type of lesser beholderkin, feed on the magic of enchanted objects. One of their eye beams allows them to do this in combat, draining one charge at a time from magical items or, for permanently enchanted ones, rendering them useless for a round. They can also swallow magical items, where items with charges lose one per round and permanently magical ones are drained over a day; the items are spat back out once the gauth has sucked them dry. They cannot, however, drain magic or spells from living creatures. They can live fine on meat, but prefer to eat magic.
** Disenchanters are blue, camel-like creatures that disenchant magical items to feed on the magic energy. They are somewhat infamous for their tendency to disenchant items the Dungeon Master feels are unbalancing the game.
** Magebanes are batlike creatures that feed on magic they siphon from spells, and tend to follow wizards around in order to have a reliable source of food. This is a problem for wizards, as the magebane's feeding tends to depower or even nullify spells. Getting rid of one is easier said than done, especially since only the affected spellcaster can see it, but one way to do it is to cross paths with a more powerful wizard; the magebane will recognize them as a superior source of food and make itself their problem instead.
** Magerippers are tiny, swarming pests that feed off of the magical power of living beings. They're a particularly danger to spellcasters and magical beings, as they'll swarm them aggressively and siphon off their prepared spells one after the other. They also gain temporary hit dice if they successfully dispel ongoing magical effects. They can't feed this way on magic objects, but still tend to crowd around them in frustrated confusion until a better food source presents itself.
** Arcane ozes can siphon arcane spells. Any arcane spellcaster within sixty feet of an arcane ooze has to make a saving throw each round or lose one of their highest-level spells as the creature absorbs its magical energy, gaining temporary hit points from the effect.
** ''TabletopGame/{{Planescape}}'': Incantifers are former members of the Incanterium faction who became obsessed with the pursuit of magic. Modern Incantifers no longer need to eat, drink or sleep, but instead subsist entirely on magic and and must feed on energy from spells and magic items in order to survive.
** Xaren eat enchanted metal.
* ''TabletopGame/HunterTheVigil'': Agonizers are extradimensional insects that feed on magic. Their normal modus operandi is to enter a human body, burrow into the brain, and extend nerve fibers through the body [[PuppeteerParasite so as to puppet their host and use it to reach magic-rich areas]]; most, however, end up dying due to scarcity of magic-rich areas on Earth. Cheiron researchers have worked out that, if the agonizer's nerve fibers are trimmed and anchored to metal spikes and the whole thing is implanted in a hunter's arm, the host gains the benefits of magic draining without losing control of their body. The implanted magic bug feeds when the hunter extends the spikes out of her hands and uses them against magical beings, allowing the symbiote to feed in a process that's agonizing for the victim. However, agonizers are still capable of making their host's life very unpleasant if left to go hungry.
* ''TabletopGame/MageTheAwakening'': The Timori [[PrestigeClass Legacy]] have built BlackMagic into their souls to feed on other mages. They start by stealing {{Mana}} to prolong their lives; the strongest can DePower mages entirely to [[ImmortalityImmorality halt their aging]] or [[PowerParasite use their stolen magic]]. Some even "farm" captive mages until [[FateWorseThanDeath their minds break from the strain]].
* ''TabletopGame/Midnight2003'':
** Aryth for Izrador feeds on magic that he siphons through the Black Mirrors. His ultimate goal is to drain all the magic in the world, shatter the veil, and return to heaven to pick up the war he left off.
** Disenchanters are camel-like creatures that consume the magic within artifacts, stripping them of their supernatural qualities as they do so.
** Spellvoids are a variant of WillOTheWisp that, instead of feeding on emotions, feeds on the magical potential of living spellcasters, disrupting their ability to work magic.
* ''TabletopGame/{{Ponyfinder}}'': The flutterponies descend from the flutters, insect-like fey that fed on magic and descended in swarms to devour any source of it that they could find, [[MageHuntingMonster including living beings]].
* ''TabletopGame/{{Shadowrun}}'': Nimue's salamanders can absorb the magic of active spellcasting, preventing the spell from manifesting and using the energy to boost their own powers. There have been attempts to train them as anti-magic security, but these have been hampered by the difficulty in getting them to feed only on specific sources of magic instead of anything in range and in keeping them from leaving when an area's dry of magic.
* ''TabletopGame/WarhammerAgeOfSigmar'':
** Vulchares are twisted avian creatures gifted to some Kairic Acolytes of the Arcanite Cults. These arcane birds have an insatiable hunger for magical energy, using their razor sharp claws and beaks to rip it from the bodies of enemy wizards if necessary.
** Those daemons with the greatest hunger for magical energy often group together into Aether-eater Hosts. These Hosts seek out and set upon enemy spellcasters so that they can leach their magical energies to revitalize their own material bodies.

[[folder:Video Games]]
* ''VideoGame/AdventureQuestWorlds'': Belrot the Fiend is a demon summoned by the Grand Inquisitor in the Citadel questline for the purpose of draining and devouring the magic of the land, [[DoesNotLikeMagic which he utterly hates]].
* ''VideoGame/BaldursGateIII'': Gale, a GentlemanWizard who joins your party, has a peculiar condition that requires that he absorb the power from magical artefacts on a regular basis, or else there will be terrible consequences. This is because he has a Netherese Orb embedded in his body, and he needs the power from artefacts to keep it stabilized: otherwise, this FantasticNuke in his body will go off, killing everyone and destroying everything in a massive radius. [[spoiler:He can have his condition stabilized on a longer-term basis under two conditions: giving him items to keep him stable until Elminster can stabilize it on the goddess Mystra's behalf, so that he can use it manually to destroy the Absolute; or deprive him of artefacts until he is desperate enough to make [[DealWithTheDevil a bargain with Raphael]].]]
* ''VideoGame/FinalFantasyXIV'': In order to exist in corporeal form, the Primals continuously syphon aether from the world around them. Because everything is comprised of aether, this continuous drain on the land destabilizes it, making Primals into {{Walking Wasteland}}s.
** The [[OurDemonsAreDifferent Voidsent]] also feed on aether, though usually on a much smaller scale.
* ''VideoGame/GuildWars2'':
** Elder Dragons are assumed to consume magic, and are as old as it, resulting in some thinking magic to be [[https://wiki.guildwars2.com/wiki/Draconic_enchanto-consumption_theory a limited resource]]. The fact that they do consume it is eventually confirmed, with WalkingSpoiler [[spoiler:Mordremoth]] being seen consuming magic from disrupted {{ley line}}s. Living Worlds Season 3 reveals that typically the Elder Dragons each consume only the portion of magic in leylines attuned to their nature. When an Elder Dragon dies, the others can devour its essence and begin feeding on that portion of magic as well, becoming even more dangerous as a result.
** Skyscales are a species of lesser dragons born when [[spoiler:Kralkatorrik tore through the Mists]]. They also feed on magic, although to a far lesser degree.
* ''VideoGame/LeagueOfLegends'' has Galio the Colossus, [[OurGargoylesRock a giant, gargoyle-shaped bulwark]] designed by the kingdom of Demacia, made out of an AntiMagic mineral called petricite. He was originally meant to just be a tower to ward off foreign armies by eating their magic, but an unexpected (and possibly intentional) result of his design is that [[BornOfMagic this causes him to come to life]], allowing him to smash the armies on his own. In gameplay, he's generally a very sturdy MightyGlacier, but he gets even greater benefit out of [[MageKiller nullifying magic-users]].
* ''VideoGame/NexusClash'': The Corruptor demon has Magic Eater powers as their signature trait. So great is the Corruptor's magic-absorbing ability that aiming a magical gun at one and ''missing'' is sometimes enough to forfeit the gun's magical attributes to the demon.
* ''VideoGame/{{Warcraft}}'':
** ''VideoGame/WarcraftIIIReignOfChaos'': The Undead Destroyer does this with its signature abilities, Absorb Mana and Devour Magic. Since the Destroyer can't regenerate mana naturally, it eats it from other units, with the former spell taking a friendly unit's mana and the latter dispelling all buffs and debuffs in an area and giving the Destroyer mana and health for each.
** The felhounds of the Burning Legion were portrayed this way in the ''War of the Ancients'' trilogy of novels. They existed to seek out enemies with magical power and would drain them until their bodies were nothing more than dried husks. Although this threat almost immediately underwent a form of TheWorfEffect, as part of Azshara's characterization was showing that, despite being one of the most powerful magic users in history and thus their ultimate food, she could have the felhounds [[FluffyTamer behaving like puppies]] in her presence.
** Elves tend to be this generally, but {{Downplayed}}. The Highborne elves drank from the Well of Eternity, a massive source of magic in the world. When that source was destroyed and the elf cultures broke apart, each group found their own substitute -- such as the Night Elves' moonwells or the High Elves' Sunwell -- because ''not'' consuming some form of magic would put them in withdrawal and turn them into mindless beasts. This fact is most obvious with the Blood Elves in ''Burning Crusade'' and the Highborne Elves in ''Legion''. The destruction of the Sunwell by the Scourge became a major problem for the High Elves and their Blood Elf descendants, as it left them desperate for new sources of arcane energy.

* ''Blog/CodexInversus'':
** Manticorats are rodents that have adapted to feed primarily on magic and magical creatures. Their normal food source are spellcasting insects, such as conjuring ants and illusionist butterflies, but they are a serious pest for wizards because they will happily gnaw on wands, eat reagents, drink potions, and chew through scrolls. Keeping them out is almost impossible, since they will simply nibble holes through shields and wards and lick off repulsive enchantments.
** Capibangels are larger relatives of manticorats that live in the Olympus Crater, one of the most magically active areas in the world. The ambient magic is so high there that they barely need to move at all, and instead can just "chew" the air and consume the magical energy there.

[[folder:Western Animation]]
* ''WesternAnimation/AladdinTheSeries'': In his debut episode, Mozenrath summons a magic eater from AnotherDimension, the Thirdac, to Earth with the intent of using it to conquer the world by weakening any and all magical defenses he encounters. To prevent the creature from attacking him, he kidnaps Genie and forces Aladdin and co. to help him place a [[RestrainingBolt control collar]] on the Thirdac to save Genie's life. Naturally, Aladdin turns the tables on Mozenrath, via Iago, and sets the Thirdac on him, forcing him to send it back to its world to avoid being eaten himself. It's also shown that the Thirdac is no threat to non-magical beings, as Aladdin beats it into the ground with his bare hands.
* ''WesternAnimation/AdventureTime': In the episode "Betty" the AntiMagic creature, Bella Noche is capable of stealing the magical power of any magical being or object through its PowerNullifier but is physically weak.
* ''WesternAnimation/{{Fangbone}}'': In "The Bill of Magic", [[EvilSorcerer Venomous Drool]] sends such a creature to attack Bill after he gains the ability to cast spells from exposure to the Toe's magic. Its a tiny white thing identified as a Voidsnarl, and while Fangbone initially laughs at the sight of it, it's shown to be no joke as it vacuums up magic through its orifices, and even Drool is so terrified of it that he cages it up using special restraints to release it.
* ''WesternAnimation/HeManAndTheMastersOfTheUniverse2021'': [[DreadfulDragonfly Gary the Dragonfly]] was mutated by the [[TheDarkSide Power of Havoc]] into a giant creature with a HorrorHunger for mystical power. His hunger was sated when he ate an ArtifactOfDoom powered by Havoc, but the Masters of the Universe and the Dark Masters were both after said artifact. [[spoiler:After getting it back, Sorceress sends Gary to the Mystic Mountains, a land where everything is infused with magic, to sate his hunger and end his threat]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Lord Tirek can drain and consume magic [[PowerCopying and gain its effects]]. Considering all ponies' abilities in this setting are magical in some way (at one point he drains an entire squad of Pegasi and they lose their ability to fly), this makes him a ''very'' serious threat once he drains enough, especially since he's even able to drain the magic of Discord, a RealityWarper PhysicalGod. A later appearance has him reveal he can only consume the magic of ''living'' things, however, which presents an issue since he can't just drain the energy maintaining a forcefield around [[MacGuffin the Bewitching Bell]] and so he needs to "borrow" the magic of one his allies to get strong enough and brute-force it open. He also reveals he can give back magic he's eaten, which is visually represented by him throwing it up.
* ''WesternAnimation/TheOwlHouse'':
** [[BasiliskAndCockatrice Basilisks]] are a [[NotSoExtinct supposedly extinct species]] that can drain the magic of witches and demons, though eating Luz's [[WildMagic glyphs]] causes them physical pain. "Yesterday's Lie" reveals that [[spoiler:the species was actually revived by the Emperor's Coven specifically to study this ability and that it merely fuels their other magical abilities like shapeshifting rather than being needed for sustenance. It's also shown that they're also able to get magic from enchanted objects (like Eda's discarded Hexas Hold'em deck).]]
** In his debut episode, Emperor Belos is shown to not be in the best of health. He recovers by cracking open a [[{{Familiar}} Palisman]] (which are ''sapient entities'') and absorbing the magic bile inside it through his eyes.
