Fictional chemical substances, A-M

From Wikipedia, the free encyclopedia

Fictional chemical substances are compounds or minerals that exist only in works of fiction (usually fantasy or science fiction). Some of the materials listed as elements below may indeed be elements, but fictional works are often vague on such distinctions. Grouping is done by what seems most likely.

Other fictional chemical substances can be found in the following lists:

Spoiler warning: Plot and/or ending details follow.

[edit] Fictional compounds and alloys

Name	Source	Uses
Adamant/Adamantine/Adamantite	European Mythology. Role-playing games RuneScape, Baldur's Gate, Final Fantasy.	The term derives from the same Greek word as Diamond. It is first mentioned in Hesiod's Theogony, in which Gaia (Earth) fashions a sickle from the substance and gives it to her son Kronos in order to exact vengeance for the unseemly deeds of his reckless father, Ouranos (Sky). Adamant is usually described as a stone or mineral of impenetrable hardness. The flying island of Laputa had an undershell of adamant, and its supporting magnet was pivoted on an adamant bearing. Note that adamantane is a real compound.
Adamantium	Marvel Comics, Warhammer 40000 some fantasy role-playing games	Once cast, this alloy cannot be bent, blunted, or broken. It is used in weapons, notably Wolverine's claws and various robots. Adamantium was invented by Dr. Myron MacLain in an attempt to recreate the unknown metal of Captain America's shield. (The shield itself does not contain any adamantium. It is sometimes said to be made of adamantium or an alloy of adamantium and Wakandan vibranium, but this is incorrect. The metal of Captain America's shield is an unknown alloy of Wakandan vibranium and steel. Adamantium did not exist when the shield was created. It was invented later, when MacLain tried to duplicate the shield's metal.) Adamantium is used in the Warhammer universe as a material for forming part of Space Marine power suits and tank/spacecraft hulls.
Adegan Crystal	Star Wars	Crystals mined on the planet Ilum. Adegan Crystals are possibly the most important component of a lightsaber. Energy is refracted through the crystal then the emitter, thus producing the blade. The color of the lightsaber blade relies on the color of the crystal. The most common colors produced by Adegan crystals are blue and green, although other colors do exist. Adegan Crystals can be synthesized, a form favored by the Sith. The Sith methods result in a red crystal and blade, but it is possible for other colors to be synthesized as well.
Afraidium	Robots	The character Fender says “I’m made of a precious metal, afraidium. It’s yellow, and tastes like chicken”.
Agatean Thunder Clay	The Last Hero, Discworld	A powerful explosive, triggered by reacting with acid. It is powerful enough that a charge set off at Cori Celesti, the hub of the Discworld, could severely disrupt the Disc's magical field.
Amazonium	Wonder Woman	Amazonium, named for the Amazons that inhabit Paradise Island (Themyscira), the only place where this metal is found, is a metal that is strong enough to stop bullets. Wonder Woman's characteristic bracelets are made of this metal. With these bracelets and her superhuman reflexes, she is able to deflect gunfire. In the live action Wonder Woman TV series, this super-durable metal is referred to as Feminum instead of Amazonium.
Animal Spirits	The Ogre Downstairs by Diana Wynne Jones	Chemical, in a strange chemistry set, that gives life to inanimate objects such as a pipe, construction set toys, toffee bars, pencils, dustballs, and dolls. Allusion to Descartes' postulated fluid that communicated between mind and body.
Anistance	The One	Anistance is an element from the Drachan Universe that can be used to make non-metallic firearms. It was discovered by researchers during an early Quantum Tunneling expedition. Anistance is relatively inexpensive to extract in the Drachan Universe and sells for a high price on the Alpha Universe black market.
Anti-Ice	Stephen Baxter	A form of antimatter, stable due to its superconductive properties, that releases vast quantities of energy when heated.
Aquitar	Blake's 7	A material believed to be necessary for The System's teleportation technology to function.
Archerite	Star Trek: Enterprise	A meta-fictional substance. A compound "invented" by Shran. Whilst pursuing the Xindi he claimed he was searching for the rare compound "Archerite".
Arcanite	World of Warcraft	An alloy created by Alchemists by combining a bar of Thorium and an Arcane Crystal. Used for the crafting of high level weapons, armour and machines
Arenak	E. E. Smith's Skylark of Space series	A transparent metal 500 times stronger and harder than the strongest and hardest steel, used primarily for spaceship armor. It is created by molding a plastic-like clay called the "matrix" into the desired shape, then coating the matrix in a weak saline solution and running an electric current across it. Pigments may be incorporated into the matrix to make opaque colored arenak. See also This site, which postulates what the modern world would be like if Arenak really existed.
Argonite	Doctor Who serial "The Space Pirates"	A practically indestructible metal. This highly valuable mineral is only found on certain planets in one sector of the galaxy. It is used for constructing the hulls of space stations and space ships.
AUM	The Illuminatus! Trilogy	A drug described as "ultimate acid", comprising hemp, RNA, LSD, and other substances in a formula that produces no "high" or hallucinations, only a state of highly receptive open-mindedness.
Azimium	The Caves of Karst by Lee Hoffman	Ionic complex behaving as an ultra-reactive halogen; hydroazimic acid is used to dissolve limestone in the submerged mines of the planet Karst.
Baldr	Ogre Battle	A metal physically similar to steel, but which is conducive to spells and magic. Equipment forged of Baldr increases the ability of the user to cast spells.
Baradium	Star Wars	A dangerously unstable explosive used in thermal detonators. It is one of the most powerful explosives in the Star Wars universe, but it is sensitive to heat and jarring.
Bassium / Bassnium / Forteium / Forteinium / Fortenium	Mega Man and Mega Man X?	It is found by Dr. Wily while making Bass / Forte. It is now used for Bass' internal system. Since whether it is a kind of energy or alloy is not stated, so it is unsure if it is for energy use or armor use. The discovery is mentioned in Mega Man 2: The Power Fighters by Wily. Also it is very likely that Zero is also made with this. The Japanese exact wording is フォルテニウム.
Bendezium	Metroid Prime	A mineral only breakable by power bomb technology.
Biphase carbide	Ogre game	Conceived by Steve Jackson as fighting vehicle armor in the Ogre game
Black Glass	Rise of Legends	A magic substance produced by a powerful, evil Geinie.
Blackrock	Ultima series	A mystical mineral that can bend space and time, and is known to resist magic. It is able to open portals to other dimensions and summon creatures through them, and it is crucial to producing the Black Moongate, by which the Guardian attempted to enter Britannia. It was also how the Avatar managed to escape the Guardian's trap on the world of Pagan (and became the Titan of Ether) and how he contained the Armageddon spell by which he ascends and the Guardian is destroyed. Blackrock is used in Ultima IX to make strong armor and a Blackrock sword, though its suitability for this purpose has never previously been established.
Black smoke	The War of the Worlds	Toxic gas used by Martian invaders. Spectrographic analysis shows an unusual triplet of blue lines. It is heavier than air and forms a black, crusty precipitate when exposed to water.
Blastolene	Jay Leno's "Blastolene Special" cars	Fictional product ('highly concentrated distillation of pure cozmic essence') purportedly produced by the fictitious Blastolene Corporation, fictional sponsors of two actually existing V12 tank-engined behemoth automobiles, including Jay Leno's Blastolene Special.
Bloodstone	Fullmetal Alchemist	A fragment of the alchemy amplification stone, the Philosophers' Stone, it is made available to members of the Seven Deadly Sins and allows alchemy without the hassle of drawing a transmutation circle.
Boranium	Stars!	One of the three minerals available for mining and construction.
Boroton	Battlestar Galactica (TOS)	In the original series, this compound was used as a fire suppression agent.[1]
Brinstone	Metroid Prime	Brinstone is a mineral from Brinstar that is breakable only by bomb technology.
Byzanium	Raise the Titanic!	A substance mined in only one place in the world, whose properties allow it to create an impenetrable missile shield.
Carbonadium	Marvel Comics	A malleable form of adamantium, in the Marvel Universe.
Carbonite	Star Wars universe	An ionic compound that has never been satisfactorily described in canon. By the rules of chemical nomenclature, the formula for a "carbonite anion" would be CO₂^2-, which was thought to be an impossible formation (formate being preferentially formed instead). Another more likely possibility is that carbonite is a metal, which are usually named with the suffix "-ite" (see List of minerals). Carbon freezing was originally a way for Bespin to transport their Tibanna gas. During Star Wars Episode V: The Empire Strikes Back, Han Solo is frozen in carbonite. The procedure leaves him in suspended animation. After this, it was used for imprisoning criminals. Following modern chemistry nomenclature, carbonite would technically be an "alloy" made of frozen carbon dioxide.
Cermicaltitan? / Right Ceramic Titanium? US: Ceratanium	Mega Man and Mega Man Zero	A kind of hard material suitable for building robots. The name is not the official translation. It is apparently the material Cut Man's blade is made out of. The Japanese exact wording is セラミカルチタン. Maybe it is from ceramics (セラミックス), calcium (カルシウム) and titanium (チタン). This material also appears in Mega Man Zero 4, as an item in the chip-making recipe.
Cheddite	Harry Harrison's Star Smashers of the Galaxy Rangers	A substance created by irradiating cheddar cheese, which allows instantaneous travel through space.
Chemical X	Power Puff Girls TV Series and Movie	As Prof. Utonium was attempting to create perfect little girls in his lab, his then assistant, Mojo Jojo, clumsily caused the accidental addition of "Chemical X", thus giving Blossom, Bubbles, and Buttercup flying abilities, heat vision, and other such super powers, whil giving Mojo Jojo super intellegence.
Cinnabryl	Mystara Dungeons & Dragons setting	A glowing red magical metal that temporarily halts the Red Curse created by vermeil (see below). Depleted cinnabryl is called red steel, and is used for weaponry and armour. Not to be confused with the real mercury ore cinnabar.
Collapsium	H. Beam Piper's works, Harry Harrison's Star Smashers of the Galaxy Rangers	According to a foot-note in Harrison's work: "Collapsium is an artificial material made of atoms with their binding energy reduced so they sort of collapse in upon themselves and are dense and heavy and that kind of thing". Piper's collapsium was used as armour and radiation shielding: once fabricated, the only thing that could cut it (eroding it atom by atom) was a high-energy particle beam from an accelerator.
Compound X07	Marvel Comics	Experimental compound developed by A.I.M.. Granted Madcap his fantastic regeneration and recovery.
Corbomite	Star Trek episode "The Corbomite Maneuver"	A meta-fictional substance - a non-existent powerful self-destruct weapon - "invented" by Captain Kirk as a bluff when threatened with destruction by a vastly superior alien vessel.
Corrostop	Transformers Universes	An anti-corrosive protective liquid created by the Autobots from rare materials. Has the property of reversing certain kinds of corrosion, while simply halting others.
Cortosis	Star Wars	Brittle rock substance that, when cut into by a lightsaber, apparently interferes with it and shuts it off, and is destroyed in the process. Incorrectly interpreted as a common ore in various Star Wars video games (when it is actually virtually unknown,) where it neither shuts lightsabers off nor is destroyed (or even brittle, for that matter.) Rock with this mixed in it can take many hours to cut through with a lightsaber, and the Emperor used it as an inner lining in his palaces to prevent Jedi attackers from utilizing their favorite door-opening technique.
Cosmium	Invasion from the Infinite by John W. Campbell, Jr.	A "metal" composed of solidified light, much like Lux or Relux, but much stronger due to being made of cosmic ray photons instead of ordinary light photons. Its specific gravity is 5007.89, its tensile strength about 200,000 times that of steel.
Craylon gas	Star Trek II: The Wrath of Khan	A toxic gas that appears on desert planets, rendering them inhospitable.
Cosmonite	Space Battleship Yamato	A "space alloy" used for energy transfer conduits. Necessary to reinforce the Yamato to withstand the side effects of firing the Wave Motion Gun. Can be found on Titan.
Crystite	M.U.L.E. video game by Electronic Arts	A highly valuable diamond-like material used in trade and commerce. Also plunder for the space pirates.
CTX	Shiri	A binary liquid explosive developed by the South Korean government. In its ground state, CTX is indistinguishable from water, but when placed under the right temperature conditions for long enough, a single liter of it can explode with enough force to level a fifteen-story building.
Cuendillar/Heartstone	Wheel of Time by Robert Jordan	A white metal substance that is indestructible except through the influence of the Dark One. Whenever it is dealt a blow, it grows proportionally harder. The same applies if the One Power is used against it. The seals to the prison of the Dark One were made from this material. Some fans of the series believe that it can be made weaker by drawing power out of it, but there is no indication to this in the books as of 2006.
Cybertronium	Transformers	A crystalline substance only found on Cybertron. Cybertronium decay causes Cybertronians built on Cybertron to malfunction. Earth-built Cybertronians are immune.
Daelren	Arcana Unearthed	A crystal capable of holding memories found in Arcana Unearthed.
Dagal	E. E. Smith's Skylark of Space series	A material conceived by E. E. Smith for ship armor in the Skylark of Space series. Dagal is stronger than Arenak but weaker than Inoson
Dalekenium	Doctor Who	The metal that Daleks are made of. Featured in Doctor Who: Monsters and Villains book.
Dargonite	Marvel Comics	Possibly the same as uru, it is capable of penetrating adamantium (see above).
Dark matter	Futurama	The fuel of the Futurama starship, a substance so heavy that, according to Professor Hubert Farnsworth, one pound of it weighs over ten thousand pounds . Leela's pet Nibbler excretes dark matter. This substance should not be confused with the real material dark matter, an astronomical term referring to elementary particles that do not emit radiation, but are detectable by their gravitational effects.
Darksteel	Magic: The Gathering storylines	A metal that is, for all intents and purposes, indestructible. Yellowish bits of magical energy orbit anything made of the substance. Used in various robots, machines, and tools. Every card with Darksteel in the title is indestructible. However, every card that is indestructible is not necessarily made out of darksteel, as is noted by colored creatures such as Daimyo Konda
Deathstone	Bleach	A granite-like material that has the ability to quickly disperse spiritual and psychic energy; causes nausea and an increasing sensation of pain to anyone trying to use those powers while near deathstone. An otherwise, dull-gray stone, this material is used in the building of the outer walls and prison structures of Soul Society as a safety precaution against intruders.
Deletium	UserFriendly	An unwanted substance typically removed from computer systems. Characterized by consistent performance failures and expensive upgrades. Also, any Microsoft product.
Dens. Drac.	The Ogre Downstairs by Diana Wynne Jones	This chemical appears in a strange chemistry set. It causes Greek Hell's Angels-type bikers to sprout from the ground like mushrooms when it is thrown on the ground. See also Dragon's teeth.
Di-Corellium (Di-Cor)	Crusader (computer game)	A tan-green colored, highly radioactive material. Di-Cor energy has replaced all other forms of power generation on Earth, making Di-Cor the most valuable substance in existence. The WEC operates a mining base on the dark side of the moon where political prisoners are forced into slave labor to mine the dangerous Di-Cor.
Dilithium	Star Trek	A reddish-orange crystal capable of moderating matter-antimatter annihilations, used in the reactors of many species' starships and a key system of a faster-than-light warp drive (Star Trek). Described by the forced-matrix formula 2<5>6 dilithium 2<:>1 diallosilicate 1:9:1 heptoferranide.
Dolemite	Futurama	A tough black mineral that won't cop out when there's heat all about. Fry's fossilized dog in the episode "Jurassic Bark" is encased in a hard shell of Dolemite, and Bender is 40% Dolemite. Reference to 1975 blaxploitation film Dolemite. Not to be confused with dolomite, which is a real mineral that is neither black nor particularly tough.
Dragon	RuneScape	A red material used to make weapons and armour, which cannot be mined, and is obtained through purchase in special stores, or slaying of monsters. It is the second strongest material in RuneScape after elf crytal.
Dreamstone	Chrono Trigger	A red, crystal-like stone of extraterrestrial origin. Dreamstone is not only a highly conductive material (approximately 15-20 times that of silver), it is also capable of absorbing and holding charges for extended periods of time. Any energy Dreamstone absorbs can be used either directly or converted for other purposes. The Zeal Kingdom’s Mammon Machine was purpose-built to make use of Dreamstone’s energy-converting abilities. Although the process is difficult, Dreamstone ore can be forged into a steel-like metal. This process was used to forge the Masamune sword. According to mythology, humankind obtained sentience when it first came in contact with Dreamstone.
Duranium	Star Trek, Ut2k4	A construction material in the Star Trek universe. Its name is based on that of the real alloy duralumin. Ut2k4 uses this as a construction material of vehicles, weapons and other objects.
Duodecaplylatomate	Galactic Patrol by E. E. Smith	This atomic explosive attains a temperature of about forty million degrees absolute in less than one microsecond. Commonly called "Duodec".
Ebony	The Elder Scrolls games	A rare, heavy, black metal used chiefly as a material for armor and weapons. Armor made from ebony is heavy, but extremely durable, and appears in glossy black with gold trim. Ebony, in its raw form, can also be used, or sold, as an alchemy ingredient. Ebony is also used in the creation of daedric armor, which is the most durable armor, but also the heaviest, and daedric weapons, which also have the best quality, but have the same drawbacks. Daedric items are usually black, red, gray, and purple in color, and have a disturbing appearance, as likenesses of contorted daedra are molded into the weapons and armors.
Eternium	Masters of the Universe (2002)	This rare metal is virtually indestructible. When refined properly, eternium is capable of being forged into powerful weapons, armor, and even prison cell doors. This unique metal makes up a large part of the alloy that He-Man's Power Sword is forged of.
Elerium-115	X-Com	This element has the unusual property of generating anti-matter power when bombarded with certain particles. This creates gravity waves and other forms of energy. It is not naturally found in our solar system and cannot be reproduced.
Elf Crystal	RuneScape	The strongest material in RuneScape. Cannot be mined, only purchased from Elves. Grown from crystal seeds, the elf crystal currently can only be made into crystal shield or crystal bow. The weapon returns to the seed once it has been dealt much damage, or has fired a certain number of shots.
Endurium	Starflight published by Electronic Arts	The item is used as a fuel for the starships in the game Starflight. Later in the game it turns out that the Endurium are actually lifeforms that have a very long lifespan. And they are the culprits for all the stars in the galaxy to flare.
Energon	Transformers	Possibly a form of compressed, solid energy. Can be found growing as purple, glowing crystals, or processed into "Energon Cubes" from mundane energy sources such as oil and electricity. Used as fuel/food by Cybertronians. Energon Crystals and Cubes are highly explosive. Exposure to concentrated energon (such as a large amount of crystals), can be hazardous to Maximals and Predacons. Overconsumption of particularly rich energon causes Cybertronians to act as if they were drunk.
Energy X	Freedom Force (computer game)	A substance, deposited on Earth by alien forces, which grants superpowers to humans. Although called "Energy", Energy X is transported in cannisters, and so apparently has some form of physical substance.
Feldon	Blake's 7	A rare, naturally-occurring crystal described as the hardest known substance in the universe. Feldon has the ability to focus and concentrate energy, making it ideal for use in small, ultra-high output power plants.
Ferrocrete	Classic BattleTech, Warhammer 40,000, Star Wars Expanded Universe	A type of concrete containing, amongst other minerals, Iron. It is unusually tough and resistant to artillery fire and is mostly used for Imperial fortifications, although some starship hulls are composed of ferrocrete.
Flowstone	Magic: The Gathering storylines	A type of stone that is composed of nanorobots. Flowstone can be programmed by focusing mental or magical energy on individual molecules. Flowstone has the specific ability to change in a 1:1 fashion with regards to the amount of damage it can do and its toughness. If a piece of flowstone becomes more damaging then it will become less resistant as is quantified by the common mechanic +1/-1. See also utility fog.
Flubber	Disney films The Absent-Minded Professor, Son of Flubber & Flubber	A rubberlike substance that rebounds from impacts with greater force than the original strike, and when exposed to directional radiation will move as if a substantial force is being applied from the incident direction of this radiation. This unlikely property leads to interesting applications such as leap-enhancing shoe soles and a flying car.
Force Metal	Mega Man X	A highly refined substance that can be equipped to Reploids, thus giving them abilities beyond those they've been designed to have.
Formic Ethers	Black Terror and Terra Obscura comics	Created by pharmacist Bob Benton, exposure to Formic Ethers grants a person invulnerability and superstrength. Benton used this chemical to become the superhero Black Terror.
Frigidite	Metroid Prime	A material that can be thawed by Plasma beam technology.
Garlicite	Harry Harrison's Star Smashers of the Galaxy Rangers	A hypothetical substance with unknown properties, the result of irradiating garlic salami. Contemplated when no cheddar cheese was readily available but never created. (See Cheddite).
GC-161	The Secret World of Alex Mack	A mutagenic chemical that Alex Mack was exposed to. The chemical's mutagenic qualities is discovered to grant various superhuman abilities, most notably telekinesis, electrokinesis, and limited shapeshifting. The show's main villain, Danielle Atron, tried to market it off as a weight-loss aid. The chemical's unpredictable nature is a major focus of the series.
Gekiganium	Martian Successor Nadesico	In the Martian Successor Nadesico anime series, the main characters often watch another (fictional) anime series called Gekigangar III. This series-within-a-series features robots built out of a supposedly indestructible alloy referred to as Gekiganium. Given Nadesico's tradition of parodying Super Robot anime, Gekiganium is a reference to the fact that many Super Robots were constructed out of rare, nigh-indestructible alloys that they are named for (or vice versa).
Ghost Rock	Deadlands roleplaying game	A black, coal-like material that burns much hotter and longer than regular coal. Powers Deadlands' steampunk technology. Infused with spirits of the dead.
Glass	The Elder Scrolls games	A very hard, very expensive volcanic glass that is used as a material for weapons and light, but very durable, armor. It is also a very valuable alchemy ingredient in its raw form.
GND	Gundam Wing	Genetic on Universal Neutrally Different Alloy. a.k.a. Gundanium (not to be confused with Gundarium, a.k.a. Luna Titanium of Universal Century Gundam). Created in high temperature plasma only formed in zero gravity, with molecular scale refinements only possible in gravitionally stable Lagrange Points. Electrically neutral and almost entirely resistant to change, it is used in the manufacture of special beam weapons and armor. Expensive cost to manufacture prohibits general military use.
Gravitational Atoms	Stephen Baxter's novel Ring	Atoms formed of microscopic black holes in much the same way that ordinary atoms are formed from protons, neutrons and electrons. Only exists in an alternate universe where the gravitational constant is many billions of times stronger than it is in our universe.
Gummi	Kingdom Hearts	A very colorful, element that is solid, yet malleable. Blocks of gummi can be fused together to construct vessels capable of safe, interdimensional travel. Also, beings with strong hearts can transform into gummis, thus allowing their physical form to be summoned from oblivion. Note: Not to be confused with the German term "Gummi" which simply means "Rubber".
Hagane	Vagrant Story	An alloy made by combining iron and bronze. Used to make both weapons and armour. (Hagane is Japanese for "steel.")
Herculanium	Blake's 7	An immensely strong material used to armor the ships of The System.
Herculite	USOS Seaview	A material conceived by Theodore Sturgeon for the windows of USOS Seaview
Hudderite	Paul Preuss's novel The Core	A compound able to scratch diamond and solid under extreme temperatures and pressures. Used as drill components to drill into unprecedented depths and horizontal distances. Composed of carbon, beryllium and silicon.
Hymetrusite	Doctor Who serial "The Horns of Nimon"	Extremely radioactive mineral utilized by the Nimon to power their gravity beam generators, which they use to build artificial black holes to enable them to migrate from one planet to another.
Ice-9	Cat's Cradle by Kurt Vonnegut	An alternative crystalline arrangement of water molecules not naturally occurring on earth for lack of a seed crystal. Has a melting point of 114.4 degrees Fahrenheit, and turns all water it comes into contact with into ice-nine. Not related to the real-world Ice IX
Ichor	Greek mythology	In Greek mythology, ichor (Greek ἰχώρ) is the mineral that is the Greek gods' blood, sometimes said to have been present in ambrosia or nectar. When a god was injured and bled, the ichor made his or her blood poisonous to mortals. The term ichor has also been used to describe the substance in vampires' veins.
Illyrion	Nova by Samuel R. Delany	Mixture or alloy of superheavy elements - mined in trace amounts, found in large ingots in stellar novas - the vastly-prized energy source in Delany's space opera novel.
Imipolex G	Gravity's Rainbow by Thomas Pynchon	A plastic invented by German chemist Laszlo Jamf and used in post-WWII rocketry. Cross-links among its chemical chains can be controllably formed and re-broken, making it the world's first erectile polymer.
Impervium	Philip Francis Nowlan's 'Space Guards' Henry Kuttner's 'Clash by Night' and 'Fury'	A synthetic metalic element, practically infinitely resistant and indestructible. A transparent, nearly indestructible material. The sub-ocean cities on Venus were built beneath giant impervium domes. Impervium is now used as the trademark for a hard, wear-resistant stainless steel alloy. Science-origin characters in the MMORPG City of Heroes can obtain 'Impervium Exposure' enhancements which increase their ability to recover endurance.
Inertron	Buck Rogers and DC comics (Legion of superheroes)	The hardest, densest substance in the DC universe. Almost completely indestructible and impenetrable.
Indurium	World of WarCraft	An ore found in Uldaman, known to be extremely heat resistant. The Goblins and Gnomes on the Shimmering Flats use the ore for their races.
Inoson	E. E. Smith's Skylark of Space series	A material conceived by E. E. Smith for ship armor in the Skylark of Space series. It has the theoretical ultimate in strength possible for any material possessing molecular structure, being 2000 times stronger and harder than the strongest and hardest steel. Inoson is transparent, and of purple color.
Irid. Colour	The Ogre Downstairs by Diana Wynne Jones	This chemical appears in a strange chemistry set. When splashed in the eye, it causes one to fade from one colour to another. Skin, hair, nails, and eyes are all affected by the colour changes.
Ithildin	The Middle-earth series by J. R. R. Tolkien	An alloy of mithril, ithildin is mainly used for decorations or secret inscriptions and has the property of reflecting only star- or moonlight.
Jumbonium	Futurama	A substance composed of extremely large versions of subatomic particles.
Kachine	Dragon Ball Z universe	A heavy, black substance that is just about indestructible. Kachine is the hardest known substance in the DBZ universe. Named for the sound it makes when tapped. Seen in the episode, "Out From the Broken Sword."
Keiyurium	Star Trek, esp. Star Trek: The Next Generation	A key component of transporter technology. The name is a nod to Kei and Yuri of anime fame (see Dirty Pair)
Kemocite	Star Trek: Enterprise	A multi-phasic isotope that has many applications, depending on the level of refinement. Kemocite was one of the key components in the Xindi weapon and was produced by a Xindi-Arboreal plant led by Gralik. Also a highly valuable contraband smuggled by Quark, Rom and Nog in the Star Trek Deep Space Nine episode Little Green Men.
Khaydarin	StarCraft	Bluish-white crystals sensitive to psychic emissions, they are used by the Protoss to power starships, armor, weapons and shields.
Krakatit	Krakatit by Karel Čapek	An extremely powerful explosive. Its name is derived from Krakatoa, an Indonesian volcano.
Kryptonite	Superman, Smallville	Usually, a crystalline mineral from the planet Krypton, it is an actual fragment of the planet itself imbued with radiation from the destruction. It is one of Superman's/Clark Kent's weakness, and the green variety is capable of killing him. See also the entry on Kryptonite for other forms of the substance.
Latinum	Star Trek	A liquid which cannot be replicated or synthesized. Used as a dominant form of currency by the Ferengi. As it is difficult to properly measure liquid for currency transactions, premeasured amounts of latinum are suspended into the solid mass of gold bullion of various sizes, leading to the standard units which are divided into four categories; bricks, bars, strips and slips of gold-pressed latinum. The exchange factor of these various units can be derived from the Star Trek: Deep Space Nine episode Body Parts (season 4, episode 25): 1 brick = 20 bars = 400 strips = 40.000 slips 1 bar = 20 strips = 2.000 slips 1 strip = 100 slips In today's money, 1 brick is worth approximately US$1000. With the latinum removed, the gold is considered worthless inasmuch as gold, like most other substances, can easily be replicated by 24th century technology; latinum is valuable precisely because it cannot be replicated. It is never properly described, but it is not impossible that an electrostatic stabilization process of some sort is used for making the colloid described. Likewise, a similar destabilization process could be used for removing the latinum, which would account for the brittle quality of gold after the procedure (see: Who Mourns for Morn? (DS9 episode)). If true, then gold-pressed latinum is essentially a gel colloid, akin to opal. Note: Despite gold's lack of value in Star Trek: Deep Space Nine, in Star Trek: The Next Generation, there are many examples contradicting the worthlessness of gold, such as Episode #67, Season 3, in which Sovak (a Ferengi) offers to pay a woman her weight in gold (not gold-pressed latinum) in exchange for an item of value to him. Sovak might have been attempting the cheat the woman, of course. For an exposition on the future of money and how latinum might come to be, see "Proposal for an Ideal Nano-Specie: Gold-Pressed Latinum" by Robert Freitas [2] [3]. There has been talk of the name "latinum" being used in the real world as an informal name for the theorized element ununquadium (element 114).
Liquid Electricity	Liquid Electricity, or The Inventor's Galvanic Fluid (1907)	The "distilled essence of electricity" in liquid form, a (usually) glowing substance easily stored in bottles. It provided fantastic energy and super-speed when used as a fuel for automobiles, aircraft, and machines of all sorts. One variant of liquid electricity could be drunk by humans, who often did so for comedic effect in silent film comedies.
Live Metal	Mega Man ZX	A metamorphic material that can contain memories or information about past events. Live Metals can be merged to create new forms.
Lor	Carson of Venus by Edgar Rice Burroughs	A tremendously energy-dense airship propellant. "Fuel for the life of the ship was aboard; and it took up very little space, for it could all be held in the palm of one hand." Lor "contains an element called yor-san (see above), as yet unknown to Earth men, and another element, vik-ro (see above), the action of which upon yor-san results in absolute annihilation of the lor," thus yielding tremendous energy as compared to a mere chemical reaction.
Luna Titanium	Universal Century Gundam	a.k.a. Gundarium, because of its use in the famed RX-78 Gundam mobile suit. Virtually impenetrable from 120 mm tank cannon ammunition, is erosion and weather proof, and has some degree of resistance from energy weapons. Manufactured in zero gravity, and, despite its name, is not made on the moon, but originally from the Earth Federation's asteroid base, Luna 2.
Lux and Relux	Islands in Space by John W. Campbell, Jr.	"Metals" composed of solidified light photons, created by condensing light so greatly that the photons are held together by their gravitational fields. Both have a specific gravity of 103.5 and are much stronger than steel, though not as strong as Cosmium. Lux is transparent and a perfect conductor of electricity and heat; Relux resembles a mirror, and is a perfect insulator of electricity and heat.
Maban	Australian Aborigine mythology	A magical substance from which karadjis, or Aborigine wise-men, derive their alleged magical powers. Its appearance is variously likened by different Australian Aboriginal tribes to quartz crystals, tektites, or mother of pearl.
Maclarium	Stargate SG-1	A fictional heavy element which, in the episode Red Sky, was used to repair the sun of a planet which the stargates' wormhole had damaged.
Magestone	Mage Knight	A crystalline substance coveted by the Atlantean Empire for technomagical experiments. Causes mutations with prolonged exposure; mutants are known as Mage Spawn.
Magicite	Final Fantasy VI; Final Fantasy: Crystal Chronicles	The remains of dead magical beings called Espers. Can be used to transfer the Esper's magic to normal humans or to machines which are then called Magitek. When worn, a person can summon the Esper the Magicite came from.
Magnozite	Legion of Superheroes	Purplish metal alloy that is strong enough to be used in forming bars and cages. Its other properties and uses are unknown. However, it is the one known substance that natives of Bismoll (homeworld of Legionnaire Matter-Eater Lad) cannot consume.
Mako	Final Fantasy VII	Energy refined from Lifestream in Mako reactors. Some mutagenic properties; often used in the military to make soldiers stronger and faster, although long-term exposure can cause Mako poisoning or monsterous mutations. When compressed into crystal form, they are then called Materia. Materi can be then worn on bangles or put in slots on weapons, which allows users to cast magic spells or summon creatures to fight for them when equipped. Materia may be natural or manufactured.
Mechalite	Monster Hunter	This blue metal is used for many low-level weapons and armour in the Monster Hunter game for Playstation 2. In the online version of the game, it may also be used in more advanced weaponry.
Met Alloy	Mega Man	This is the material used to create the hat of a Mettool. Other names include Mettonium, and Nerpium.
Misc. Pulv.	The Ogre Downstairs by Diana Wynne Jones	This chemical appears in a strange chemistry set. When two people eat grains of the foul-smelling (and tasting) chemical, they swap bodies. The only way to switch back is to eat another grain.
Mithril / True-silver	The Middle-earth series by J. R. R. Tolkien and is featured in various videogames,such as RuneScape.	Malleable, shiny metal which was skillfully shaped by dwarves. It had both a decorative purpose, especially in an alloy called ithildin, and also was hard and light enough for armour. The metal was much prized after the fall of Khazad-dûm where it was chiefly mined.
Mixmaster	Tremors	A compound that combines organisms at the chemical level (DNA). Engineered in a secret government lab underneath Perfection, Nevada by, among other people, a scientist named Cletus Pofferberger. Among things created by Mixmaster are the hyper-vicious beast 4-12 and a cloud of bacteria that feeds off of moisture. Specifically designed not to affect human DNA.
Mizzium	Magic: The Gathering storylines	A highly resilient and heat-resistant alloy invented by and named for Niv-Mizzet, the genius dragon guildmaster of the Izzet League of Ravnica. A variant known as invizomizzium is equally tough but transparent. Mizzium transreliquats are capable of shifting their functions to those of any nearby mechanical device.
Molecular Acid	The Alien series	The blood of a xenomorph acts like an extremely potent acid, melting through almost any substance in seconds. Captain Dallas remarked that he had "never seen anything like that except molecular acid."
Mono-hydrazine	Salvage 1	Liquid, non-cryonic rocket propellant for the Vulture spacecraft. Highly concentrated as one semi-tanker full on near-continuous low thrust took the spacecraft on lunar round trip. Highly explosive if not kept at a relatively low temperature.
Moonsilver	Exalted	Also known as lunargent, moonsilver is considered by the Lunar Exalted to be a gift from their patron, the moon goddess. It must be harvested by moonlight, using no crafted tools, forged at night and cooled only with water that has never seen the sun. Swords made of moonsilver are more accurate, bows shoot farther and armor is much lighter. Like the protean Lunars, moonsilver can shift into new forms easily.
Moon Stone/Moon Crystal	Skies of Arcadia	A crystalline substance used as an all-purpose plot device in Skies of Arcadia; Moon Stones dropped by the six Moons of Arcadia have different elemental properties (Yellow Moon Stones are electrical, Red Moon Stones are fiery, etc.) and can be used to fuel magic and technology. Moon Crystals are very concentrated Moon Stones; each is as powerful as thousands of less concentrated Moon Stones. The Moon Crystals can be used to control the Gigas, gigantic living weapons of the ancient world.
