List of fictional elements, materials, isotopes and atomic particles

List of fictional elements, materials, isotopes and atomic particles

This list contains chemical elements, materials, isotopes or (sub)atomic particle that exist primarily in works of fiction (usually fantasy or science fiction). No actual periodic elements end in "-ite", though many minerals have names with this suffix. Some of the materials listed as elements below may indeed be minerals, alloys, or other such combinations, but fictional works are often vague on such distinctions. Grouping is done by what seems most likely.


Fictional elements and materials

Name Source Uses
Acoustium Batman Beyond Featured in the episode "Shriek", an alloy that amplifies sonic vibration.
Adamant Greek Mythology,Various later works A strong, hard metal. has numerous mentions going back to antiquity. The term initially referred to any unknown super-hard material but in Medieval works it may also refer to magnetic materials.
Adamantite Greek Mythology, Dungeons & Dragons, Dwarf Fortress, RuneScape, World of Warcraft, and other games. A strong metal. Sometimes spelled "Adamantine". Presumably derived from the classic term and fictional material Adamant, which has numerous mentions going back to antiquity; the term initially referred to any unknown super-hard material, and finally settled on diamond. Often green.
Adamantium Marvel Comics, Final Fantasy, Warhammer 40K, Morrowind, Maplestory Adamantium is a series of closely related compounds of iron mixed with chemical resins. It has been frequently described as being virtually indestructible. Substance of the skeleton of Wolverine.[1]
Afraidium Robots The robot Fender claims to be made of this metal. "It's yellow," he states, "and tastes like chicken."
Agricite SWAT Kats It is a metal mineral that occurs in the ground and is mined outside of MegaKat City. It is incredibly strong and is used to make hardened objects like tanks.
Alkahest Alchemy A powerful substance, most known as a "universal solvent", which could dissolve everything. It was sought in alchemy.
Allanite Steel The Tunnel Allanite steel was the special superior alloy developed by Richard "Mac" McAllan that made the construction of a transatlantic tunnel possible in the 1935 film The Tunnel, based on the novel Der Tunnel by Bernhard Kellermann.
AM2 The Sten Chronicles Antimatter mineral from parallel universe (only known to Emperor), the unique energy source that provides all power needs of mankind and the Earth Empire.
Amazonium DC Comics Found only on the island of Themyscira, this metal is used in alloys to create extremely strong and lightweight armor.[2] An example of an amazonium alloy is found in Wonder Woman's bracelets. See also feminum.
Andrium Master of Orion Andrium Armor is the fourth strongest type of armor in the Master of Orion series.
Antidermis Bionicle Antidermis, a green-black liquid or gas, it makes up the essence of the Makuta. The Piraka use it to enslave other creatures, namely Matoran, whom it makes susceptible to suggestion. It also strengthens Brutaka's species and makes the Skakdi violently ill. The only known substance which counteracts its effects is Energized Protodermis.
Anti-plastic Doctor Who—"Rose" Anti-plastic is a substance that destroys plastic, including creatures made out of living plastic, such as the Nestene Consciousness. Can be made by mixing materials such as hair spray, nail polish and other substances like such, as seen in Autonomy.
Arcanite (Warcraft) Warcraft universe A dull, flexible metal that can be forged to an edge sharper than iron and steel.
Arenak (Skylark series) Skylark of Space Epoxy-like substance that when catalyzed by salt becomes useful armor much harder than the best Terran steel. Salt is highly coveted by both opposing sides warring over a world that the Skylark visits because of its extreme rarity on that world. The more barbaric side (Mardonale) was about to kill the Skylark crew to obtain the salt from their bodies, before being stopped by Prince Dunark, leader of the more civilized side of the war.
Argonite Marvel Comics Earth-712, RuneScape A radioactive substance which weakens the fictional superhero Hyperion. (So just as Hyperion corresponds to Superman, Argonite corresponds to kryptonite.) In RuneScape it appears as a light blue metal found only in Daemonheim.
Atium Mistborn series A metal which allows Mistborn to see a few seconds into the future, thereby allowing them to anticipate the moves of an opponent. It also enhances the mind to cope with and understand these new insights, effectively turning a Mistborn invincible for a short time. Atium burns very quickly.
Atmosphereum (also often spelled as "Atmospherium") The Lost Skeleton of Cadavra An extremely rare element, abundant in outer space, which among many other uses is a power source and capable of raising the dead. If obtained and researched, it would certainly have countless benefits for science.
Australium Team Fortress 2 An element originating from Australia that is similar to gold, the major difference being the nucleus resembling a pair of boxing kangaroos. It can adapt and transform itself into different states and forms, therefore making it extremely valuable and sought-after. It enhances the intelligence of whoever holds it and is known to turn complete idiots into geniuses. Side effects includes a steroids-like effect and a peculiar love for beer. Aided in the invention of Teleporter Pads, Invisibility Watches, Life Extending Machines, and the "entire spectrum of mustache sciences".[3]
Axonite Doctor Who—"The Claws of Axos" Axonite is supposedly a "thinking" molecule that can replicate any substance, but, in the end, turns out to be a malevolent element that intends to spread itself across the cosmos in order to feed itself.
Balthazate Guild Wars A crystalline material found beneath the Shiverpeaks. Balthazate looks similar to quartz crystals roughly half the size of a man. It is a highly potent explosive as shown when four crystals bring down a large portion of a cave when ignited.
Balthorium ("Balthorium-G") Dr. Strangelove, The Middleman (TV series)-"The Obsolescent Cryogenic Meltdown" In Dr. Strangelove it is an element used in the Russians' doomsday device. It is possible that this is a mispronunciation, on the part of actor Peter Bull, of the words "Cobalt-Thorium G," as both (real) elements can be used in atomic weapons to increase the amount of dangerous nuclear fallout, which agrees with the sense in which "Balthorium" is used in the movie.

In The Middleman (TV series) it is a very rare mineral which is necessary to power The Candle's Melting Ray.

Basidiumite (also Brumblium) Eleanor Cameron's Mushroom Planet series A slightly greenish solid, twice the density of uranium. Infragreen spectrum. Makes up the blue-green planet Basidium.

Beskar Star Wars A metal used by the Mandalorian warriors. Also known as Mandalorian Iron.
Black RuneScape A mid-strength metal in RuneScape. Its origin is unknown as it cannot be mined or smelted.
Blasium/Blazium Buck Rogers in the 25th Century (TV series)-"Twiki is Missing" A white rock-like substance that resembles sugar cubes, and when ignited, a small amount "can blow up a small moon." Buck uses it later to reduce the mass of a frozen-oxygen meteor that is about to enter Earth's atmosphere.
Blingidium Wigu "The rarest compound in the universe." A large statue made of this substance in the shape of Topato is dug up by Wigu's family. Touching it leads to a feeling of ecstasy ("feeling light" and "tasting watermelon"). It is destroyed by the Space Mummy.
Blurite RuneScape A rare lightweight bluish-tinged metal. Mostly used for decoration as it is too soft for weaponry.
Boing! Judge Dredd Plastic of extremely high elasticity
Bolonium or Bolognium (or likely Baloneyium) Futurama, The Simpsons, etc. A fictional element used to describe something as impossible or nonsensical.[5] In the Futurama episode "A Clone of My Own", Cubert Farnsworth used the term "Weapons-grade bolonium" as an insult to his "parent," Hubert Farnsworth's technology demonstrations. An episode of The Simpsons featured an Oscar Mayer promotional periodic table of elements with the element, which states that the atomic weight of bolonium is "delicious" or "snacktacular."

The Star Trek The Motion Picture official blueprints published in 1980[6] specifically identify the Klingon K't'inga-class battle-cruiser as possessing bolognium engine shields.

Bombastium Uncle Scrooge An element each atom of which, when dropped in a barrel of water, is capable of generating a barrel containing a different flavor of ice cream, according to Carl Barks. It is discovered by the Brutopians. Scrooge McDuck pays one trillion dollars and six kitchen sinks for a soccer ball-sized sample of it in an auction in a 1957 story in Uncle Scrooge comics #17. In a Duck Tales story it is used to power a time machine invented by Gyro Gearloose.
Brightsteel Brisingr of the Inheritance Cycle A mysterious metal that comes from meteors and is extremely hard. It was used by Rhunön, an elven smith, to make all the swords of the Dragon Riders, including Eragon's sword, Brisingr. Swords made of brightsteel, and enchanted in the right way, will never break. She found the brightsteel in deposits throughout Ellesméra, one deposit often being enough to make several swords. Swords often took multiple weeks of preparation and work to be made. Rhunön was unable to find any more by the time Eragon needed a sword, though, so he had to find it using a prophecy of a werecat, Solembum, had given him, which was to look under the Menoa Tree when he needed a weapon. He found a piece of brightsteel ore there, and was able to make his sword with Rhunön's help.
Bulerite Macrolife Bulerite which is used to build the huge cities which house the Earth's (and colonies) teeming millions, are at the pinnacle of their influence and wealth. Unfortunately, it is discovered—-too late-—that the substance is inherently flawed, in that after a time it destabilizes and self-destructs with spectacular results.
Bydogen R-Type A gel-like substance created by human militaries as a living weapon, which grew out of control into an alien menace. The Force modules contain and use bydogen to augment the weaponry of the attached R-Type ship.
Byzanium Raise the Titanic! A highly powerful radioactive element, the only supply of which was believed to have been transported in a vault aboard RMS Titanic.
Calculon The Adventures of Tintin, Destination Moon Discovered by Professor Cuthbert Calculus. This substance has a silicon base and can resist very high temperatures. It was one of the scientific discoveries that enabled Professor Calculus to plan a manned mission to the Moon.
Caesium-frankolithic-mixia-lubidium-rixidixidexi-doxidroxide Red Dwarf, Only The Good... A chemical famous in its era, it was the cure for a virus that was eating away at the hulls of the mining ship, the Red Dwarf. It is not to be confused with Caesiumfrankolithicmixialubidiumrixidexidixidoxidroxide, which is a completely different compound.
Capsidium Teenage Mutant Ninja Turtles (1987)—"The Fifth Turtles" Creates energy during planetary conjunctions if the lights hit the Capsidium, used by Krang and Shredder to power the Technodrome.
Carbonite Star Wars Episode V: The Empire Strikes Back A cryonic alloy, carbonite was originally used to keep tibanna gas fresh. The chamber in the Cloud City of Bespin was reconfigured to provide stasis for Luke Skywalker for his transport to Emperor Palpatine. It was tested on Han Solo, whom Boba Fett then transported to Jabba the Hutt to collect a price on Solo's head. It was then used to transport criminals. One known side effect of being encased in carbonite is temporary blindness.
Carbonium Fury3 Found exclusively on the planet L24-D. Carbonium explodes with 48 times the power and radiation damage of a fusion bomb.

Cavorite H.G. Wells' The First Men in the Moon and The War of the Worlds Cavorite is impervious to gravity and can shield other materials from its effects. It is used to shield a craft from Earth's pull, allowing easy flight. It was named after its discoverer, Dr. Cavor, who used it to travel to the Moon. It also coats Martian flying machines, although it is referred to as a "gravity-blocking substance", and not Cavorite. It is also used in The League of Extraordinary Gentlemen, Robert Buettner's Orphan series, A Deepness in the Sky, Dr Grordbort's Contrapulotronic Dingus Directory (written and illustrated by Greg Broadmore, WETA Studios, New Zealand), and the second-season premier of Warehouse 13.

Cernium-116 Knight Rider (original series) in episode "Knight of the Juggernaut" An isotope produced by bombarding "a mass of plutonium with titanium ions..." It "is more radioactive than uranium...and highly unstable..."
Cheddite Harry Harrison's Star Smashers of the Galaxy Rangers The result of a college prank where a student placed a chunk of cheddar cheese in a powerful cyclotron. The resulting material was dense, black and produced a powerful energy field when exposed to electricity. This field could be used to flip a spacecraft through enormous distances virtually instantaneously when incorporated into a Cheddite drive unit. Not to be confused with the real-world explosive compound of the same name.
Chelonium The Science of Discworld A material which according to the Unseen University wizards mostly makes up the world-bearing turtle "Great A'Tuin." Since they can do a test to determine its (non)existence in Roundworld, they are probably correct.
"Chemical X" The Powerpuff Girls When Professor Utonium was creating the Powerpuff Girls, he accidentally added this chemical to the mixture of sugar, spice and "everything nice." It is responsible for granting the girls their super-human powers. Its chemical opposite and neutralizer is a mysterious substance called "Antidote X."

Chronoton Star Trek, Futurama, Teen Titans, Jets 'N' Guns, Mighty Morphin Power Rangers From Greek: Χρόνος (Chronos, "time") + -ον (on, "elementary particle"). Alternate spellings: "chroniton." Associated with manipulating or traveling through time in Star Trek, as well as in Futurama, where it also has rejuvenation effects. A chronoton bomb in Teen Titans destroys chronotons in a given area, stopping that area's progression through time. A "chroniton rifle" is the most powerful weapon in Jets 'N' Guns.
Cinnabryl Mystara Dungeons & Dragons A glowing red magical metal that temporarily halts the Red Curse created by vermeil. Depleted cinnabryl is called red steel, and is used for weaponry and armour. Not to be confused with the real-world mercury ore cinnabar.
Claudia Last Exile An element used to power vanships and larger airships. It glows a light blue and is found naturally in solid form. However, while in liquid form, it generates an anti-gravity field when put through certain processes, which allows the aforementioned ships to fly. Its solid form is also used as a unit of currency, simply called a claudia.
Collapsium H. Beam Piper's Terro-Human Future History stories Collapsed matter (i.e., no longer possessing separate electron shells) plated in extremely thin layers (a "micro-microinch" being typical) onto more conventional metals and used as shielding for spacecraft and reactors. May refer to degenerate matter or neutronium. No direct relationship to the same term used in the works of Wil McCarthy.

Corbomite Star Trek (1966), "The Corbomite Maneuver" Commonly believed to be fictional within the fictional Star Trek universe. The supposedly non-existent substance was invented by Captain James T. Kirk as part of a bluff to prevent the destruction of the U.S.S. Enterprise I by another vessel. The material and device (both called "corbomite" in the bluff) supposedly redirect any destructive energy back to its source, destroying the attacker. The material has since appeared in various other series and video games set in the Star Trek universe.
Cordite Metroid Prime In its purest form, Cordite is a smokeless powder composed primarily of nitrocglicerine. An elaborate processing procedure transforms this powder into an extremely dense solid. Cordite is so strong, in fact, that in laboratory tests it consistently withstood direct hits from war-grade missiles. Cordite can only be weakened by simultaneous strikes with multiple missiles. Cordite can be destroyed by using a super missile; a charged energy blast with five combined missiles. Not to be confused with the real-world smokeless propellant compound of the same name.
Corrodium Ben 10 An alien element that is capable of mutating certain lifeforms. Prolonged exposure is required for the mutations to be permanent.
Corrodium Zero Effect Referenced when Zero is doing Gloria's taxes and she inquires about the fictional "Corrodium 3 deduction", which he explains pertains to "class 3 decay toxins, such as corrodium and maalgorium"
Cortexrulestheworldium Crash Team Racing A chemical element discovered in the epilogue of Crash Team Racing. Recognized and named by the conceited scientist Doctor Neo Cortex, when he returned to scientific research. Little is known about it, besides its atomic Number, 117.
Cortosis Star Wars A lightsaber resistant metal.
Crapcrapium Futurama: The Beast with a Billion Backs In a dispute about the relative hardness of Diamondium and Diamondillium, Crapcrapium is referred to as a disparaging comparator. The implication is that Crapcrapium is soft.
Croach Codex Alera A translucent, waxy substance created by the Vord, an alien race. It slowly absorbs and dissolves bio-matter, and is then itself a source of sustenance. To the Vord it is both air and food, and they provide spider-like creatures that tend to its constant maintenance. Croach is spread wherever Vord make their home.
Chogokin Z / Super-Alloy Z Mazinger Z This is the metal utilized to construct the eponymous Super Robot of the anime series Mazinger Z. In the series, Chogokin Z is created from the newly-discovered element Japanium. Other variant metals include Chogokin New-Z, used to construct Great Mazinger, and Chogokin New-Zα, which was the basis material for Mazinkaiser. The series' sequel Grendizer features an unrelated but still highly similar metal called Space Alloy Gren.

The term "chogokin" has since become a trademarked name for toys and models manufactured in Japan by Bandai. It is also informally and frequently used by collectors to describe toys with high die-cast metal content, or in a nostalgic sense toward those earlier Super Robot series and toys.

Chrysadamantium John C. Wright's The Golden Age Trilogy A transuranic element used as a building material; can only be damaged through the use of black holes and antimatter

Crystallium Robert L. Forward's novel Dragon's Egg A crystallized compound of degenerate matter, part of the internal chemistry of the cheela, used by them to form bone-like structures.
Cybertronium Transformers Original Series A quantum metal, useless by itself (only found on Cybertron-like planets, and possibly artificially created by the Quintessons), that, when alloyed with other metals, creates the dimensional storage space useful for transformations—extra supplies, components, weaponry, or the like. The Dinobots were created without this metal, which explains their huge humanoid bodies.
Daeyalt RuneScape A turquoise ore, mined by human slaves of the vampyres. All that is known about it is that the ore had "some magical hoobery-joobery on it" and that "those vampyre types are after the hoobery-joobery".
Dalekanium Doctor Who A metal used by the Daleks as a component of their armoured casings. Also, named in an alternate reality, as an unstable explosive powerful enough to penetrate those casings.
Dark Iron World of Warcraft A metal found in the Burning Steppes and the Searing Gorge. Favoured mineral of the Dark Iron dwarves and the Blackrock clan of Orcs. To be worked with, the use of the Dark Forge and the Dark Anvil, within the Blackrock Depths, is required.
Dark Ore The Legend of Zelda: Spirit Tracks
Dark Matter Futurama Dark matter is the biological waste of Nibblonians. First introduced in "Love's Labors Lost in Space," the extremely dense black material, usually clumped in perfect spheres, is the primary source of power in the 30th century. It also exists in another form, dark matter oil, in "The Birdbot of Ice-Catraz" a dark matter oil spill on Pluto caused the penguin population to become ultra-fertile. In the movie Bender's Game, it is explained that all dark matter is linked by two crystals that give it its properties as fuel. "Dark Matter" is also a legitimate term in cosmology.

They plan to use Candy's Radio towers to generate high frequency electromagnetic waves for the transmutation of destinium into fortunate.
Destronium Transformers Animated A liquid that helps Cybertronians repair themselves. It is plentiful on Cybertron, but on Earth, humans were only able to synthesize small samples. At high speeds, destronium can get very volatile and would take out half a city the size of Detroit if it detonates.
Deutronium Lost in Space A substance with many uses, refined into a flammable liquid which the Robinsons required as fuel for the Jupiter 2. It is mined as small white pebbles by either drilling or pumping out of the ground. Some species consume deutronium as food, including the Cyclamen and the People of the Green Mist.
Diamondillium Futurama: The Beast with a Billion Backs A substance harder than anything in this universe. The only substance that rivals its hardness is diamondium, though odds are it may be the same substance under a different name.
Diamondium Futurama: The Beast with a Billion Backs A substance harder than anything in this universe. The only substance that rivals its hardness is diamondillium, though odds are it may be the same substance under a different name.
Dilithium Star Trek A fictional crystalline mineral, in the universe of Star Trek, that is used to regulate the anti-matter-powered warp drives that allow starships to travel faster than light. (Although dilithium is a real molecule, it is a gas with none of the properties of the fictional crystals, and the writers were unaware of its existence.)
Dilustel DC Comics Captain Atom's metallic "skin" is composed of a portion of the alien being known as Silver Shield, and is called Dilustel. Pieces of the alien's metal body were used in Project Atom, and on later subjects like Major Force and Bombshell. The metal is almost totally indestructible. Only X-Ionizer technology can cut the metal and the magical guns of the Crimson Avenger were able to crack his skin. Breaking through it causes Captain Atom to Quantum Jump as if he had absorbed too much energy.

Durallium Elite/The Dark Wheel Spacecraft in the computer Game Elite and the short story The Dark Wheel (based on Elite) by Robert Holdstock were made of this material after it was treated by being time stressed. It was the only known material able to withstand the rigors of passing through Witch-space, the method of interstellar travel used in the game and novella.
Duralloy Master of Orion series Duralloy Armor is the sixth strongest type of armor in the Master of Orion series.

Duralloy is also featured in some role-playing games, namely Metamorphosis Alpha and Gamma World. In both of these games, Duralloy has properties vary similar to Adamantium from the Marvel Universe. In Gamma World, Duralloy can also be found in special containment drums, that maintains it in a molten state by a magnetic field. Once the seal is broken, the liquid metal must be used quickly (about a minute) before it cools down and becomes permanently solid. The cool down is rapid, and absorbs background heat.

Duranium Star Trek Spacecraft hulls are made from the super metal alloys duranium and tritanium.
Durasteel Star Wars Durasteel is one of the most used alloys in the Star Wars universe. Its qualities include: being very flexible, resistant to heat and cold, monumentally physically stress resistant, and the color brown. Because of these it is the most common material for the manufacture of spacecraft hulls.
Dureum E. E. Smith's Lensman series Artificial, ultra-dense metal, the only known material that will not occupy the same space as other matter (coming from elsewhere) in a hyper-spatial tube, hence used in armor, weapons, etc. that might encounter anyone or anything a tube. Invented by the Eddorians and used in their exploration of other universes, given to their subject races in the Lensman universe, and eventually discovered and copied by the Galactic Patrol.
Durium The Infinite Atom Durium was an ultra-strong, extremely dense, infusible sapphire blue alloy of made from resistium and other "ultra-elements" (which had an atomic structure consisting of a nucleus of "negatrons," orbital protons and without any electrons present in the atom at all), in The Infinite Atom by John W. Campbell, Jr. Durium would also be featured in several of the later works of E.E. "Doc" Smith.
Dwarfstar Alloy/Hull Metal Various Ships' hulls from various sci-fi novels starting in the 1920s were said to be built using this ultra-strong material. It is an extremely condensed state of matter, i.e. Neutron Star material, and used as a plot device to make nearly invulnerable ships without having to invent some implausible new materials.
Eitr Norse Mythology, Tomb Raider Underworld A bright blue liquid, where life comes from.
Electromatter Futurama: The Beast with a Billion Backs Described by Hubert J. Farnsworth as "Matter's Badass Grandma". A pink substance that mainly exists in the dimension on the other side of the anomaly; can only be broken or punctured by more electromatter. The tentacles of the planet-monster, Yivo, are made from electromatter.
Element 99 Singularity Also known as E99, the Element 99 was a powerful source of energy. Scientific research on the element discovered the E99's ability to alter time, and thus, the substance was used by Dr. Viktor Barisov to create the TMD, or Time Manipulation Device.
Element 115 Tomb Raider III A turquoise element named by Area 51, Element 115 came down to Earth on a meteor which landed in Antarctica. The element was worshipped by the Polynesian's ancestors who once lived there (naming the place "Kuma-Kuma"), until their sixth leader Mauki was born without a face, as a mutilating reaction to the material. The people then fled to Polynesia. The artefact can shoot powerful turquoise blasts, and can also be used to speed up and personally alter evolution, even evolving an already developed life form.
Element 115 Dark Reign: The Future of War Discovered in the outer planets in the early days of exploration of the solar system, Element 115 was used by Alpheus Togra, founder and head of the Togra Foundation in his experiments where he successfully converted the angular momentum of electrons directly into mass. It is unique in that it was the only element with an atomic weight greater than 92 to not undergo spontaneous fission immediately.
Element 115 Call of Duty: Zombies A dark red element, and is exclusive to the Nazi Zombie backstory. It arrived on Earth on meteors, including one in Japan where the third Nazi Zombie map is set, the meteors emit strange noise and electrical pulses. Element 115 has been used to power most of the out-of-place high tech such as the teleporters, and is thought to have created the original zombies.
Element 115 Seven Days This transuranic element salvaged from the Roswell crash by the scientists behind Operation Backstep generates a time distortion field around the Backstep Chronosphere, displacing it through space and time.
Element 152 DC Comics Element created by Mon-El by combining gold, silver and iron. It has anti-gravity properties and was eventually used in rings, allowing members of the Legion of Super-Heroes to fly. Arm Fall Off Boy is thought to have gained his superpowers through mishandling this element.
Element 250 (Sturginium) Dystopian wars Discovered in an Antarctic crevasse, this powers the world in 1870. It has numberless strange qualities; hardening tin twentyfold, lightening steel twentyfold, whilst on the other hand being able to soften artillery shells and human skeletons, it can be used in reactors and also has teleportational qualities. Leakages are known to create interspacial portals, which can link together to form mildly dangerous singularities, and if a vehicle's core explodes, it may teleport it "into the ether", from whence it is not known whether recovery is possible.
Element X Ben 10 Element of extraterrestrial origin that, when combined with a precise mixture of an unspecified form of iron ore at high temperatures, has enough explosive capacity to destroy an entire solar system.
Element Zero Mass Effect Also known as eezo, generated when solid matter is affected by the energy of a star going supernova. When subjected to an electrical current it produces a field that increases or decreases the mass of an object. Used in a number of applications, the most noticeable being FTL travel. Humans exposed to this element while still in the womb may gain the ability to generate their own fields and are known as biotics.
Elementium Max Steel: Forces of Nature Isotopes giving power over the classical elements Earth, Water, Wind, and Fire.
Elementium World of Warcraft An element that came from the Elemental Plane, thus making it very rare in Azeroth. It is capable of channeling elemental energies. It is used to craft special artefacts such as Thunderfury, Blessed Blade of the Windseeker.
Elephantanium Duck Dodgers A form of rock that mutates whoever touchs it. The person remains what he is mutated into as long as he is touching it. It may make the person addicted to it when they look at it.
Elephantigen The Science of Discworld A material which according to the Unseen University wizards makes up the four world-bearing elephants: Berilia, Tubul, Great T'phon and Jerakeen. Since they determine with a simple test that it does not exist in Roundworld, they are probably correct.
Elerium-115 UFO: Enemy Unknown The element, atomic number 115, upon which all alien power systems are based. It facilitates space flight by emitting gravity waves under particle bombardment. Used as a fuel for advanced craft, and to power weapons and devices based on alien technology.

Comes from only one location: the Rock of Eternity, the home of the wizard Shazam and guarded by all members of the Marvel family. The Rock was destroyed in the 30th century, causing the fourth Captain Marvel to search for the pieces. Following the explosion, however, eternium proved to be harmful to her, in a manner comparable with Kryptonite's effect on Kryptonians. Also referenced in World of Warcraft as the most difficult lockbox in the game, only dropped in high level dungeons and can only be opened by experienced lockpickers. Is also a metal rarely found in all mineral veins in Outland. A material called eternium also appeared in the He-Man and the Masters of the Universe cartoon, where it was the material He-Man's breastplate and harness ware made of, serving to magnify his strength.

Titanium-A Halo In the Halo series, Titanium-A Armor is composed of a high-grade Titanium-50 alloy, specially strengthened at the molecular level. Titanium-A has numerous uses throughout the UNSC due largely to titanium being lightweight and extremely strong, with a high tolerance to heat. It took new found importance after the beginning of the Human-Covenant War; To contend with the Covenant's plasma weaponry, Humans needed armor that would withstand the heat of the directed plasma. Despite its strength and resistance to heat, the Titanium-A plating is usually boiled away within seconds, and does not effectively dissipate the plasma. Its primary use is as armor for ships. UNSC Frigates have sixty centimeters of plating on their hull, and UNSC Destroyers have up to two meters of plating. Larger ships were known to have even more, such as ten meters to a supercarrier. The UNSC uses Titanium-A for construction of bases as well, to make them less susceptible to destruction. Places such as HIGHCOM Facility Bravo-6, CASTLE Base and Camp Hathcock used Titanium-A armor in their superstructures.

Fictional isotopes of real elements

Name Isotope of Source Uses Reality
886Ar Argon Judge Dredd An unstable element that is used to propel rounds fired from a Lawgiver. The isotope does not exist; the heaviest known isotope is 53Ar.
138Cs Caesium Mission: Impossible (Snowball In Hell) In this episode (the 21st in the series) the team has to prevent a sample of this isotope, the key to a low-cost nuclear arsenal, from getting into anti-American hands. Its autoignition temperature is 21°C (70°F) and thus has to be kept refrigerated in the tropical climate where it resides. The isotope does exist, but decays with a half-life of 33 min and thus would be infeasible for a nuclear weapon.
82Cm Curium Brødrene Dal og Spektralsteinene The McGuffin in this TV series, where Professor Slatters claims that with it he can find a cure/vaccine for the common cold. He and the Dal brothers go on an expedition to search for a meteorite with a sufficient amount of it. They do find one, but is there alloyed with umulium (impossibilium), making the 82Cm unobtainable. Curium has an atomic number of 96, so the existence of this isotope would require a nucleon of negative mass, which has not currently been found.
Quadium (4H) Hydrogen The Mouse that Roared Hydrogen normally has no neutrons. Deuterium and tritium have one and two neutrons respectively and are used in hydrogen bombs. Quadium has three neutrons, and is in the story capable of blasting an entire continent off the face of the Earth. This isotope exists but only for a very short time, making any use in a bomb impossible.
80Ir Iridium Riptide According to the book, one second of direct exposure is equivalent to a lethal dose, with a reading of 3217.89 Rads/hr from 15 metres away. The blade of St. Michael's sword was forged from it.[13] 80Ir does not exist; the lightest known isotope is 164Ir.
186Pu Plutonium The Gods Themselves An isotope of plutonium which is too unstable to exist in our universe but which exists naturally in parallel universes whose strong nuclear forces are more intense. This is utilised as a source of energy where it is turned into 186W, releasing electrons in the process. The description of this isotope is entirely correct; the lightest known isotope of plutonium is 228Pu.
Quantium any element, but most commonly potassium Babylon 5 This rare and expensive substance used in jumpgates is formed when ordinary matter is subjected to the stresses of a supernova, pushing some of its electron pair-bonds into hyperspace. The most commonly found form is derived from 40K, giving quantium-40. The name was coined by David Strauss in response to a request from the show's creator.[14] 40K is a naturally occurring isotope of potassium which is used to date rocks. However, the method of obtaining quantium as described has not been demonstrated in real life.

There are only a few known planets containing Naquadriah; one is Langara (the home of Jonas Quinn) where large deposits were accidentally created from natural Naquadah deposits when a bomb using a relatively small amount of the material was tested by a team of human scientists, radiation from the explosion started the chain reaction. It was originally created in relatively small amounts millennia ago by an unknown Goa'uld scientist. Unprotected exposure can lead to brain damage, delusions and/or schizophrenia. It has been said to have a half-life of several thousand years. The other known sources, presumably naturally occurring ones, are known as 'Icarus Class' Planets. Two have been found by Earth so far. The first was used (and ultimately destroyed) in the construction of Icarus Base and the dialing of the Ninth Chevron to the Ancient starship Destiny using the Stargate, several billion light years away. The second was used by the Lucian Alliance for that same purpose but, due to instability of the power transfer and the lack of sophistication in the algorithms used for the power transfer, was also destroyed. Earth is currently in negotiation with Langara for use of their naquadriah deposits as a lifeline to funnel supplies and personnel to Destiny
Thyrium-261 Thyrium Matthew Reilly's novel Temple This isotope is found only in a binary star system, in the Pleiades. It is capable of generating enormous power in the right reactor configuration. It leaves no radioactive waste byproducts after use. It is also capable of forming a subcritical mass, detonating with enough power to vaporise a third of the Earth's mass, propelling it out of orbit, away from the sun.

Fictional (sub)atomic particles

Name Source Uses
Bigon Discover Magazine A particle supposedly discovered by French scientists, which although it exists for just millionths of a second, it is the size of a bowling ball. "The Bigon" was an April Fool's joke article from issue no. 4/1996.
Bogon Jargon File In Quantum bogodynamics, a particle generated by politicians, used-car salesmen, TV evangelists and suits in general. Bogon absorption causes human beings to behave mindlessly and machines to fail (and may also cause both to emit secondary bogons). The antiparticle of the cluon. In Ratchet and Clank: Going Commando, the galaxy that the titular characters are transported to is the Bogon Galaxy, most likely as a nod to the particle.
Chronon The Fireclown by Michael Moorcock The "atoms of time", used by the Fireclown to create the "Time Fire".
Cluon Jargon File In Quantum bogodynamics, a particle generated by those who Get It. Cluon absorption causes human beings to act reasonably. The antiparticle of the bogon. Sometimes called a validon.
Craptron Instant Physics A particle found in Washington D.C. A joke particle from the book.
Dust His Dark Materials An elementary particle that is the basic unit of consciousness. Not a constant; is generated by and confers sentience on animals in a positive feedback loop; in the context of humans, the human brain is a focusing mechanism for Dust. The more conscious the entity, the more Dust is around them. Permeates all universes and passes among dimensions.
Fat electron Jargon File In Quantum bogodynamics, an electron that gains weight via bogon absorption. Clogging the narrow micro-electronic pathways of microchips, it is believed to be the cause of microprocessors failing.
GN Particle Gundam 00 Particles created by GN Drives which are generally of a greenish colour (except if produced by GN Tau Drives) and have a wide variety of uses, e.g. radio and radar jamming or even influence on human biology in various ways.
Gravioli Futurama A nonsense particle briefly mentioned in the episode Roswell That Ends Well, one of the forms of radiation emitted by a supernova. Presumably interacts strongly with microwave photons.
Kingon/Queon Discworld A particle hypothesized to exist by philosopher Ly Tin Wheedle. Particles that travel faster than light and transmit 'monarchy', since when a monarch dies, the successor is instantly the new monarch, with no gap or overlap between the two. The exception is when these particles are intercepted by their anti-particle, the republicon. The theory that this effect could be used for really fast information transmission (by carefully torturing a small king) was never fully developed, because at that point, the bar closed.
Kojima particles Armored Core series (debut in Armored Core 4) The Kojima particles named after his fictional creator are heavily radioactive particles used primary for shielding and defense but also for propulsion, weapons and energy source. The most common use is as a barrier that protects the gigantic mechs in Armored Core that also allows them to move at high speeds, giving them a huge advantage over other combat vehicles and weapons. These particles absorb the kinetic energy of projectiles and other weapons reducing the dammage given to almost none. Depending on the weapon, the more power it fires, the more the kojima barrier stops, but of course draining the shield integrity. Another aspect of this particles is that they are extremely polluting and lethal due intense radiation and can cause heavy envirorment dammage. They are visible at high densities or upon impact with something and look greenish.
Nucleoproton Big Guy and Rusty the Boy Robot The exact nature of this particle is never fully explained, but its applications are well-documented. Nucleoprotons appear as particles that are bright green in appearance and glow. Their application seems to widely vary. They apparently can be used as an energy source; a weapon, if nucleoprotons are directed to create a particle cannon; and a source of propulsion.
Oz GURPS Technomancer A particle that carries magical energy, found in places where boundaries between alternate possible realities are thin. Mages are able to control the flow of particles through spells, effectively reshaping the universe as they see fit.
Planetary Particle Yu-Gi-Oh! 5Ds A particle used to power the Ener-D reactor in New Domino City.
Reson Discworld Roughly translated as thingy, these particles combine to make up thaums. Similarly to real-world quarks, they come in five different flavours: Up, down, sideways, sex appeal and peppermint. They are considered to be the fundamental particles of reality (see Moving Pictures (novel)).
Snarks, Boojums Star Trek II: The Wrath of Khan novelisation The sub-elementary particles that quarks are made from, discovered by Drs. March and Madison, two Lewis Carroll fans involved with Project Genesis. Named after the creatures in The Hunting of the Snark.
Swivel Caballo de Troya This book gives a lengthy, detailed "technical" description of a time travel process by an "inversion of quantum swivels" which permits the supposed author "The Major" to witness the last weeks of Jesus's life through a time-travelling device sent back in time by the US military in an Israel base in 1973.
Tachyons Numerous examples in sci-fi A tachyon is any hypothetical particle that travels faster than light. In many fictional settings it is taken that this involves travelling through time and they are invoked as an integral part of, or even shorthand for, time travel devices.
Thaum Discworld A Thaum is the basic unit of magical strength. It has been universally established as the amount of magic needed to create one small white pigeon or three normal sized billiard balls. The thaum, hitherto believed to be the smallest possible particle of magic, was successfully demonstrated to be made up of /resons/ (Lit.: 'Thing-ies') or reality fragments. Currently research indicates that each reson is itself made up of a combination of at least five 'flavours', known as 'up', 'down', 'sideways', 'sex appeal' and 'peppermint'. The device that is used to measure the strength of magical fields is a thaumometer.
Thaumaturgon Bas-Lag A particle that mediates thaumaturgy or magic in the Bas-Lag novels of China Miéville.

Fictional allotropes and polymorphisms

Name Source Uses
Ekti Kevin J. Anderson in his novel Saga of Seven Suns A fictional allotrope of hydrogen which is used to power the Ildiran stardrive, the only feasible method of interstellar travel at the start of the series.
Ice-nine Kurt Vonnegut in his novel Cat's Cradle It is described as a more stable polymorph of water than common ice (Ice Ih) which instead of melting when above 0° Celsius (32° Fahrenheit), melts only when the temperature is 45.8°C (114.4°F). Therefore it will be frozen at room temperature. When ice-nine comes into contact with liquid water below 45.8°C, it acts as a crystal "seed", and causes the solidification (freezing) of the entire body of water as crystalline ice-nine.
