Want to burn asbestos but haven't got the time? Need to KillItWithFire but regular fire isn't enough?

Fear not! For here at TropeCo, we have the ultimate form of fire, direct from the FireAndBrimstoneHell! And it's available in [[TechnicolorFire all standard designer colors]]! (Blue, green, deep red, and black are our [[{{Pun}} hottest]] sellers!)

The way it's supposed to be better versus regular fire is sometimes explained, sometimes not, but rest assured that if it's hellfire, it's stronger!
Oh, it's probably BlackMagic, but c'mon: it's called ''Hell''fire. It's not like this stuff is powered by [[CuteKitten the adorableness of kittens.]]

[[PoweredByAForsakenChild Unless it IS fueled by actual kittens, of course...]]

The point is, hellfire is not physical in origin, and doesn't have to play by the same rules as normal fire. Ignition without a source of oxygen? Sure! Scorching things that are supposed to be fireproof or ''made of fire''? You bet! Notable when it comes from a story without any references to Christianity.

Not to be confused with the [[http://en.wikipedia.org/wiki/AGM-114_Hellfire Hellfire laser-guided missile]], nor the expansion to the original ''VideoGame/{{Diablo}}'', nor the {{Toaplan}} shmup. [[Disney/TheHunchbackOfNotreDame Or the]] VillainSong.

Contrast HolyHandGrenade and FauxFlame.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Hiei from ''Manga/YuYuHakusho'' has two attacks that are comprised mainly of hellfire. The first is Fist of the Mortal Flame, which uses the fire from human hell to pummel the opponent. The other, much more [[DeathOrGloryAttack dangerous]] attack is Dragon of the Darkness Flame, which is an enormous dragon made of flames from the demon hell.
* This is Ioryogi's signature power in ''{{Kobato}}''.
* [[EpilepticTrees Theories that it summons fire from hell]] aside, Amaterasu from ''Manga/{{Naruto}}'' doesn't have any connection to hell, but exhibits many traits as hell fire: special color (black), extremely hot ([[ConvectionSchmonvection supposedly as hot as the sun]]), has impossible properties (can burn non-flammable objects, even underwater & can cause even [[EldritchAbomination Bijuus]] who shrug off lesser attacks to cry out in pain), and is very hard to put out (can't be put out unless you wait for a week, seal it, or the user snuffs it out).
** Zetsu actually says at one point that Amateratsu is supposedly "black hellfire". It's real nature is never clarified.
** The tailed beasts' chakra isn't really fire of any sort, but when a Tailed Beast's host put out enough of the chakra, it can incinerate anything it touches... even the host himself.
* In ''{{Slayers}}'', there's a distinction: for example, Fireball is Shamanism spell -- it calls upon fire spirit. Gaav Flare, on the other hand, was BlackMagic using the power of Chaos Dragon, one of Dark Lords. Defunct after Gaav's demise, of course. Reflecting [[TheBrute Gaav's nature and power level]], it's much nastier and burns ''through'' the first target, then whoever was behind it...
* In ''Manga/MahouSenseiNegima'', one of Negi's BlackMagic techniques is called ''Incendium Gehennae'', which can be loosely translated as "[[UsefulNotes/{{Judaism}} Flames of]] [[http://en.wikipedia.org/wiki/Gehenna Gehenna]]".
* In ''{{Bastard}}'', Dark Schneider's ultimate spell [[SpellMyNameWithAnS Halloween/Helloween/Harrowing]] summons fire that is hotter than the ''sun'', completely obliterating an Efreet MADE of fire.
** Unless this is a variation between manga and anime, he used Exodus to take out Efreet. And he created a fire that was hotter than the sun by harnessing the heat of Efreet's own fire spells. With a nice middle finger to ConvectionShmonvection, the room made of stone is actually melting. BEFORE this "fire hotter than the sun" was created. And the actual proper name of his ultimate spell is "Helloween", after the band. The anime changed some of the spell names for fear of copyright issues. Such awesome spell names included are "Poison, Megadeath, Guns & Roses, etc". It's a post apocalyptic fantasy manga with a LOT of rock references thrown in.
* It's not explicitly HellFire, but [[OnePiece Admiral Akainu's]] fists are made of lava, which apparently is hot enough to burn fire itself. Of course, [[MemeticMutation swords are hotter than lava.]]
* In ''Manga/BlueExorcist'', [[TechnicolorFire blue flames]] are the sign of Satan. Rin, a [[HalfHumanHybrid son of Satan]], tends to erupt into them. This is a ''problem'' due to FantasticRacism and also a boon; there isn't much that can handle them [[spoiler: after they are the only demonic flames that attack the ''physical'' and the ''spiritual''.]]
** [[spoiler:Shima]] can summon a demon that uses black hellfire.
* In ''Manga/FairyTail'',
** Zancrow summons and controls pitch-black flames that can burn and injure Natsu. Natsu is normally immune to heat and ''eats'' flames. [[spoiler: Natsu eventually manages to [[CrowningMomentOfAwesome eat Zancrow's flames]], giving him the power boost to defeat him.]]
** The dragon Atlas Flame describes his flames as hellfire.
[[/folder]]

[[folder: Card Games]]
* The ''TabletopGame/MagicTheGathering'' card [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=189229 Demonfire]]. If it kills a creature they're rendered DeaderThanDead.
** Then of course there's the actual [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=201141 Hellfire]] card, which wipes out all non-black creatures (being a black spell, it's assumed that most if not all of your own creatures will be exempt) [[CastFromHitPoints at a price]].
[[/folder]]

[[folder: Comic Books]]
* Weapon of choice for ''Comicbook/GhostRider''. It burns hotter the more sins the target has.
* Spider-Man, in his cameo role, [[LampshadeHanging lampshades]] this in ''ComicBook/{{Runaways}}''.
-->"Ah, good old hellfire, when regular fire simply wont do."
* ''ComicBook/FantasticFour'' example: Doctor Doom opens a portal to Hell, and Johnny and Franklin are pulled inside. Johnny gets out, but not without being badly burned; especially notable considering he's the ''Human Torch'', master of flame in all forms, who hasn't suffered a burn in, like, [[ComicBookTime thirteen years]]. Yeah. Hellfire. It'll mess you up.
** Though Johnny later finds out that the holy flames of an archangel's FlamingSword are even ''more'' painful.
* {{Transformers}} [[http://tfwiki.net/w2/images2/7/76/Thefallen.jpg The Fallen]] is permanently WreathedInFlames after joining Unicron.[[http://tfwiki.net/wiki/The_Fallen According to his TFWiki article,]] these flames are the manifestarion of his Chaos powers, and have the bonus effect of ridding him of any goodness still within him.
* {{Etrigan}} can use this, exhaling soul burning fires from his mouth. Though he can also project it from his hands.
[[/folder]]

[[folder:Fanfic]]
* In ''DeptHeavenApocrypha'', this is [[TheMedic Fia's]] slightly-less-holy HolyHandGrenade; she still can't control it yet, though.
* ''ThirtyHs'' grants Franchise/HarryPotter the power to wreathe his fists in "Holy Fuckfire" with which he punches the heads off vampires, sending them into the past of Mars, or... something. Notable for being evidently a holy force rather than an infernal one, and... powered by swearing, or something.
* ''PokeWars'' depicts Will-O-Wisp in this form. It is a sinister dark purple/blue flame that ignites anything it touches and cannot be extinguished.
* Rather unsurprisingly, [[spoiler: [[BigBad Daemon]]]] from the ''FanFic/TamersForeverSeries'' uses this as his primary technique. He seems to enjoy immolating people a bit ''[[AxCrazy too]]'' much.
[[/folder]]

[[folder:Literature]]
* While not specifically from hell, fiendfyre in ''Literature/HarryPotter'' is hot enough to destroy a [[SoulJar horcrux]], something which is rather difficult to do. And is sentient. And malevolent. And a lot harder to put out than to start. And very difficult for a normal wizard to control, so it's not like you can practice with it.
* Harry Dresden of ''Literature/TheDresdenFiles'' is enabled to generate this from ''Literature/BloodRites'' to ''Literature/WhiteNight'' due to a [[spoiler:psychic copy of a Fallen Angel in his head.]] It adds more power to his destructive magical attacks, but he has to struggle against TheDarkSide.
** After [[spoiler:demonic shadow who gives him access to hellfire dies saving Harry's life]] he finds out that [[spoiler:the archangel in charge of maintaining free will, and God's own holy hitman, Uriel]][[note]]The one who killed all of Egypt's firstborns[[/note]] has gifted him with Soulfire, the fires of Creation itself. It fits the trope just as well as normal Hellfire - it makes the spells more "real," and thus more powerful, but at the cost of some of Harry's soul (though it regenerates so long as he has some left. It regenerates more quickly if he takes time to nurture it; for example, [[spoiler:going on a date with Luccio at the end of ''Small Favor'']]). The Soulfire also burns an unusual color - it usually adds a bit of a silver tinge, depending on how much he uses and what spell he ties it to.
** There's also Summer Fire, a gift granted by the Summer Court. So far, though, it's only been used against its [[IncrediblyLamePun polar opposite]] in the form of the Winter Fortress, where it is understandably extremely destructive, so no word on if it's actually any hotter or more powerful (though it does leave a trace in the user's fire magic from then on).
* Only the forge of Mount Doom is hot enough to destroy the [[LordOfTheRings One Ring]], though that might be as much symbolism as related to the heat of the lava itself. (In the film, [[ConvectionSchmonvection it's not like Frodo or Sam were exactly burning up]].)
** It was theorized that Dragon's Fire would be sufficiently hot, but there weren't any more dragons...[[Literature/TheHobbit D'oh!]]
*** Dragonfire could destroy the ''lesser'' Rings of Power (the Three, Seven and Nine), and in fact that's what had happened to some of the Seven Rings of the Dwarves), but Gandalf says that not even the fire of Ancalagon the Black (the greatest of all dragons) could destroy the ''One'' Ring.
* In the ''Literature/BetsyTheVampireQueen'' books by Mary Janice Davidson, the titular queen's half sister Laura is the daughter of Satan (don't ask). As such, one of Laura's powers is to summon a sword made of hellfire. It can transform into a crossbow in the blink of an eye, and is implied to always be hanging at Laura's hip, invisible when she doesn't need it. Hellfire only disrupts magic, so it passes harmlessly through mundane humans but incinerates vampires instantly. However, Betsy's odd status as [[TheChosenOne Queen of the Dead]] means that the sword neither passes harmlessly through nor incinerates her, but stabs her like a normal sword would. It gets stuck and must be pulled out, but leaves no wound behind.
* Referred to as 'Wizard's Fire' in ''SwordOfTruth''. It's described somewhat like a magical version of napalm, a "liquid flame" which won't be put out by smothering, even if it's just a little bit of flame; in fact, it will just set on fire whatever you use to smother it. Beyond that, an even stronger version known as [[CastFromHitPoints Wizard's Life Fire]] appears at a few points, used as a DesperationAttack by wizards who are about to die anyway.
* The science fiction novel ''[[Creator/StrugatskyBrothers Roadside Picnic]]'' mentions a substance called "[[ImportedAlienPhlebotinum Witch's Jelly]]", left behind by the mysterious alien visitors, that will burn (or corrode?) through just about anything, leaving a flaming pit in the ground as it goes.
* ''ASongOfIceAndFire'' has wildfire and dragon's breath. Wildfire is the exclusive creation of the Alchemist's Guild, a liquid something like magical napalm which burns with an intense green flame that's impossible to extinguish (it can burn water!), and seems to be almost alive in larger conflagrations. It seems to be based on Greek fire. Dragon's breath is apparently much hotter than normal flames, and is said to possess magical qualities, such as its use in the creation of [[{{Mithril}} Valyrian Steel]].
* ScienceFiction variant in Creator/CharlesStross' ''[[{{Accelerando}} Glasshouse]]'' - "Blasters" are very simple weapons based around a couple of wormholes. One end opens at the end of your pistol; the other opens into ''a sun''.
* A certain spell in ''ChroniclesOfTheRaven'' makes very powerful jets of fire that supposedly home in on enemies. Have a guess at its name.
* Literature/TheWheelOfTime has [[DangerousForbiddenTechnique balefire]], a magical flame so strong that it not only kills you, [[RetGone it burns your recent past out of history]]. One scene has a bad guy killing several major protagonists, and then being killed by balefire - the recently-dead protagonists are brought back to life(very confused), because the baddie retroactively didn't exist to kill them. Enough use of this destroys the very fabric of reality. [[spoiler:It's also the only way to [[DeaderThanDead prevent the Big Bad from resurrecting]] his assorted [[TheDragon Dragons]] after they are killed.]]
** [[NonIndicativeName Despite being called "balefire,"]] it is not actually ''fire'' of any kind except metaphorically, as it "burns the threads from the Pattern. " It appears as a white beam that more or less instantly annihilates what it's aimed at.
** Note that during the War of Power, in the series BackStory, ''entire cities'' were apparently destroyed by balefire before both sides stopped using it, [[EvenEvilHasStandards due to the danger]] [[EvilVersusOblivion to reality itself]].
* ''Literature/TheBannedAndTheBanished'' also uses the term "balefire" for fire from evil magic. It has many properties of normal fire, but it freezes instead of burns. (Good spellcasters can also create fire, but once started it functions like normal fire.)
* The destructive, rare and difficult to control white fire from ''Literature/TheChroniclesOfThomasCovenant''. Curiously, "Hellfire!" is one of Thomas Covenant's favorite sayings.
[[/folder]]

[[folder: Tabletop Games]]
* In ''DungeonsAndDragons'', it's manufactured by Devils and can burn creatures ''made of fire''. Ever watch a fire elemental burn to death? [[strike: Not pretty]] Absolutely awesome. (Some sources say that it's "not truly fire" at all" but an evil form of energy unique to Hell.) Particularly useful since about half the monsters in the game are resistant to normal fire to some extent.
** Adapted in a third-party setting called "TabletopGame/{{Infernum}}". There, it's basically negative spiritual energy (despair, pain, misery) given physical expression as sickly green-black flames, which are capable of consuming flesh, bone and soul with equal ease and which thus makes it especially powerful against creatures like demons and angels. It consequently has its own damage type (and damage resistance), so ordinary Fire resistance is worthless against it (although, conversely, a character with only Hellfire Resistance is defenseless against Fire damage).
** For a less evil version, the Searing Spell feat from ''Sandstorm'' can make your normal fire spells burn hot enough to deal partial damage even to creatures immune to fire.
** The cleric spell ''flame strike'' has shades of this, attacking with a 50-50 mix of fire and divine energy. The fire can be resisted, but the other half can't.
** The first edition of D&D had ThePhoenix radiate this. To get a resistance to this fire, you needed one of the feathers dropped by said Phoenix as a spell component.
** Third edition has Mephistopheles, the Lord of Hellfire, who grants warlock followers the power to draw upon his powers of hellfire that function as normal fire damage, except that effects that provide resistance or immunity to fire damage don't affect them. He claims to have discovered Hellfire; whether this is true or not, he is, no doubt, better at using it than any other devil, and has created many horrible devices associated with it, such as [[HumongousMecha Hellfire Engines]].
** Hellfire Warlocks are a type of mortal wizard who can harness this form of energy, mentioned in the 3.5 Edition. (Not all of them are evil, but most are.)
*** The Sanctified One PrestigeClass grants worshippers of Kord the ability to make their fire-based spells NonElemental.
*** The ''Book of Exalted Deeds'' supplement also has a spell which creates "heavenlightning" that functions in the same way.
* Warpfire in ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'' is ''evil'' fire drawn from the Warp. Unsurprisingly, it's chiefly the weapon of daemons, their servants, and the odd race of evil rat-men (who have Warpfire flamethrowers). Tzeentch's daemons in particular are little more than living flamethrowers, and vehicles dedicated to Tzeentch in 40k are covered in eldritch fire. There's also the Holocaust power, which is incredibly dangerous and deadly, and burns Demons just as well as anything. Bonus; it makes resurrection impossible and even kills immortal demons.
** [[WarGod Khorne's]] Daemons often bear [[FlamingSword weapons wreathed in this]]. The final Khornate talent for [[EvilOverlord Eliphas the Inheritor]] in Dawn of War II also apparently engulfs him in this.
* ''MutantsAndMasterminds'' classifies Hellfire as a type of magical energy that looks like fire but isn't. It can be any color, most elements, and act as numerous other powers.
* In an interesting variation, infernal powers in ''{{Exalted}}'' tend to use the burning, poisonous light of Ligier, the demonic Green Sun of Malfeas, in the same manner as characters in other settings use hellfire. In addition to the usual attributes of a {{Hellfire}}-analogue, this can also infect victims with Green Sun Wasting, a [[NauseaFuel truly horrifying]] supernatural disease that makes Ebola look like the common cold in comparison.
** The fandom often jokes that Ligier's fire is basically [[ILoveNuclearPower radioactive]], which technically makes the Green Sun a more "realistic" sun than the Daystar.
* Essential Flame in ''{{GURPS}}: Magic'' is similar in concept to this but seems to be based more on Plato than Christianity.
** In the Dungeon Fantasy books Demonologists can summon blasts of Hellfire. It [[ArmorPiercingAttack totally ignores armor]] and is even able to incinerate spirits but [[CastFromHitPoints saps life from the user]].
* In ''TabletopGame/WerewolfTheApocalypse'', powerful servants of the Wyrm use balefire, which is sickly green and has effects similar to severe radiation burns. It is also used by certain infernalists in TabletopGame/VampireTheMasquerade.
** And in ''TabletopGame/HunterTheVigil'', members of the Lucifuge get the ability to throw about Hellfire as [[HalfHumanHybrid part of their special heritage]].
[[/folder]]

[[folder: Video Games]]
* In the ''VideoGame/{{Exile}}''[=/=]''VideoGame/{{Avernum}}'' series, quickfire is an artificial, very powerful magic flame that ignites even thin air to create a wall of flames that spreads as fast as a man can run. Nothing short of cold rock or very powerful magic can stop its spread.
* Hellfire is a damage type in the {{roguelike}} game ''ToME''. Unlike normal fire, it cannot be resisted and evil creatures take double damage. The game also has holy fire.
** Similarly, the Roguelike ''crawl'' has a damage type hellfire - some monsters resist it, players can't (contrary to almost all other types of damage). Hellfire attacks are always ranged area effects. They're most commonly used by various demonic monsters at the high end of the power scale, but can also be invoked by player characters with a specific mutation or wielding one of a very small set of artifacts.
* ''VideoGame/WorldOfWarcraft'' has this as a - surprise! - warlock spell, which spews apparently unholy flame in a radius around the warlock, dealing decent damage per second in an aoe but also injures the warlock. Oddly enough, the self-damaging part is the thing warlocks use it for as they have more powerful [=AoE=] but dying to hellfire doesn't cause durability loss.
** Chaos Bolt, another warlock spell, is probably a better example. It fires a bolt of chaotic fire that goes right through absorption effects and ignores fire resistance. It does not, however, work against targets that are completely immune to fire damage.
** Also, NPC demons tend to use green fire, leading to some running jokes about giving warlocks green fire.
*** They did give warlock's green fire. There is a long quest chain that allows a Warlock to turn all his spells that use fire into green fire.
** [=WotLK=] also introduced the concept of dual-element spells, primarily so you can't easily resist them by stacking a specific magic resistance (usually fire). Spellfire, Spellfrost, Frostfire, etc.
* In the first VideoGame/DevilMayCry, the Ifrit gauntlets [[EmpathicWeapon describe their power]] as being hellfire. The description for the Frost enemy claims that, while impervious to volcanic fire, they're susceptible to higher levels of incendiary. In other words, [[KillItWithFire use Ifrit against them]].
* ''Franchise/{{Castlevania}}''[='=]s Dracula has a three-to-five-directional fireball attack by this name. On occasion, he cranks up the damage factor and throws big black METEOR-fireballs at you.
** Alucard can mimic the three-fireball and two-meteor-fireball attacks EXACTLY in ''VideoGame/CastlevaniaSymphonyOfTheNight''. It is so immensely satisfying to be able to pull Dracula's shenanigans on his henchtwits. To gamers unfamiliar with the old NintendoHard console titles and their relatively slow Belmont heroes, the fireballs may seem like small potatoes, but even very skilled, hardcore gamers have been reduced to incoherent howling by the original ''VideoGame/CastlevaniaI'' and the [[VideoGame/CastlevaniaChronicles Sharp X68000 remake]] of that title. (We do not mention ''VideoGame/CastlevaniaIIIDraculasCurse'' around these gamers. They will go insane.)
** Shanoa from ''VideoGame/CastlevaniaOrderOfEcclesia'' can do this, too, with the Dominus Anger glyph, but not without downsides. There's only one per shot, it's Dark property instead of Fire, which means it's watered down against many endgame bosses (like Drac himself), and, most importantly, [[CastFromHitPoints it consumes HP equal to one sixth of Shanoa's capacity per shot!]] If that isn't enough reason to not use it, let's not forget what it's part of and where it came from...
** Soma Cruz, can also perform the three-fireball attack if he equips the right soul. In ''VideoGame/CastlevaniaAriaOfSorrow'', [[spoiler: it's one of the three souls he needs to equip during the battle with the DiscOneFinalBoss to unlock the path to the true ending]].
* ''Franchise/{{Pokemon}}'': Throughout the series, various Pokemon have attacks that are much like hellfire, one example is Ho-Oh's Sacred Fire.
** A more serious version is Shadow Fire from XD. Exclusive to Moltres, it's a Shadow-empowered Flamethrower attack that will barbecue even the sturdiest Water, Rock, and Dragon Pokemon. Then again, Shadow power is super-effective against everything other than itself...
** ''Black'' and ''White'' also gives us the inaccurate but powerful Inferno, which will ''always'' leave a burn. To further the resemblance, it's actually called Purgatory in Japan.
** The Gold Pokedex entry for [[{{Hellhound}} Houndoom]] is meant to evoke this trope; apparently, the pain inflicted from the flames it breathes will never go away.
* Hellfire is generally the name given to the Ifrit summon's best attack in the ''FinalFantasy'' series, or Belias in ''VideoGame/FinalFantasyXII''.
* Hellfire is also the fire elemental Spirit attack in ''BatenKaitos: Eternal Wings and the Lost Ocean''.
* ''CityOfHeroes'' soon-to-be-released Demon Summoning powerset for Masterminds has a few demons that attack with hellfire, as well as giving the Mastermind a [[WhipItGood whip made of it]]. While regular fire attacks have the secondary effect of igniting enemies for additional fire-type damage over time, hellfire's damage over time is toxic-type, and applies a damage resistance debuff to its targets.
* Scorpion of ''MortalKombat'' fame has power over hellfire as a side effect of being undead. He pretty much only uses it to kill people by breathing it on them.
** One of his special moves from Deadly Alliance onward lets him summon flames from the ground.
* ''VideoGame/NeverwinterNights2'' Warlock's PrestigeClass, Hellfire Warlock. Guess what their magic blasts are made of.
* [[PlayerCharacter The Demi-Fiend]] in ''VideoGame/ShinMegamiTenseiIIINocturne'' can equip a powerful Fire magatama which allows him to use a spell called ''Hellfire''. There is a stronger version, called ''[[ThePowerOfTheSun Prominence]]''.
* Hellfire is an attack in ''BravelyDefault'' that is appropriately used by [[{{Hellhound}} Cerberuses]], which deals 1.25 fire damage to all enemies. You can utilise the attack yourself by absorbing it with the Vampire's Genome Drain.
[[/folder]]

[[folder:Webcomics]]
* A particularly [[RuleOfCool awesome]] application of this comes from the D&D webcomic ''{{Darken}}'', where the main character is a {{Hellfire}}-[[KillItWithFire flinging]] EvilOverlord-in-training:
---> '''Garganon the Ancient Red Dragon''': You ''burned'' me!?
* The titular character of the webcomic ''ZebraGirl'' has the ability to summon hellfire which makes anyone she's mad at spontaneously combust. In a subversion, EpilepticTree wisdom states that the burns made are skin deep, so that the victim can be fried again...and again...and again.
[[/folder]]

[[folder:Web Original]]
* ''Website/DragonCave'' has a species called "Hellfire Wyverns". The submissive males are the bright fiery red usually associated with this trope, while the more violent females are the bright blue of hotter flames.
[[/folder]]

[[folder: Real Life]]
* [[http://en.wikipedia.org/wiki/Thermite Thermite]] is a reaction between a metal and a metal salt (typically iron oxide and aluminum). The reaction generates temperatures of approximately 2500 C and releases molten iron. Its also self-oxidizing so good luck putting it out. Soldiers used it during WorldWarII to melt Jeep engines and artillery cannons. Modern-day troopers use a similar concoction for similarly destructive purposes.
** By comparison, a candle burns at 1000C, while a propane blowtorch can go up to 2000C
** There were attempts to incorporate thermite into artillery shells and missiles by the Soviets. Although thermite can burn through thin sheets of metal effortlessly, the idea ended up being dropped -- unlike a certain incendiary gel, thermite burns up far too quickly and cannot be easily spread over a large area.
* Industrial electric arcs invoke this trope, from arc welding (no not [[ArcWelding that type]]) to [[http://www.youtube.com/watch?v=_j2jESz7Zl8 electric arc steelmaking.]] Arc steelmaking is where humans effectively use man-made lightning to melt steel and rock at temperatures hotter than a volcano, with the arc furnaces drawing as much power (or more) as a 747 at takeoff - or a small town. [[http://www.nucor.com Nucor's]] Crawfordsville, Indiana plant, at full bore, needs a quarter of a typical nuclear power plant's output. Electric arc furnaces sound like a [[GatlingGood Gatling gun]] at artillery calibers. Arc temperatures average about 6000C - steel melts at 1525C.
* [[http://en.wikipedia.org/wiki/Chlorine_trifluoride Chlorine]] [[http://pipeline.corante.com/archives/2008/02/26/sand_wont_save_you_this_time.php trifluoride]]. During WWII, it was produced by UsefulNotes/NaziGermany under the name "N-stoff" ("Substance N") as an incendiary/chemical weapon for use against the Maginot Line. After the Manstein Plan eliminate the need for a direct assault on Maginot, research and production was halted because there were no other conceivable uses and it was dangerous as hell. Production was restarted at Germany's giant chemical arms factory beneath the town of Falkenhagen sometime after the Battle of Stalingrad, but thankfully the Red Army captured it before N-stoff saw operational use. Colorless, poisonous, a stronger oxidizer than ''oxygen'', a stronger fluorinator than '''fluorine gas''' and hypergolic (''i''.''e''., it starts making things burn immediately on contact) with nearly anything, it will cause things to burn that absolutely should not be flammable - things like ashes, bricks, water, sand, test engineers, and ''asbestos''. If you try to dump sand on Chlorine Trifluoride in order to put it out, it will instead merrily ''proceed to burn the sand'' (and then the ground ''beneath'' the sand). The closest thing to actual hellfire the real world has to offer.
** The major product of most chlorine trifluoride reactions is hydrogen fluoride, a very corrosive acid that is extremely toxic beyond even beyond its acidity. Spilling a bit on a few centimeters of skin can easily destroy the bones underneath[[note]]It's not burning it down to the bone, it's going through your skin first[[/note]], as well as any nearby nerves faster than they can transmit the pain of the acid corroding your skin. Also, it can deplete your blood of serum calcium and give you a heart attack. Hellfire indeed.
** [[http://www.youtube.com/watch?v=M4l56AfUTnQ Here is a French demonstration video showing off CLF3 interaction with what would be otherwise standard protection for your average chem lab a small pane of Plexiglas, a rubber glove, clean leather, not-so-clean leather, a gas mask, a piece of wood, and a wet glove.]] In any other lab, some of these items would be good, sensible protection, Here, they are merely "things that have not oxidized yet."
* In many ways, chlorine trifloride is the gentler cousin of [[http://pipeline.corante.com/archives/2010/02/23/things_i_wont_work_with_dioxygen_difluoride.php Dioxygen]] [[http://en.wikipedia.org/wiki/Dioxygen_difluoride Difluoride]]. This quote sums it up nicely:
-->When 0.2 (mL) of liquid dioxygen difluoride was added to 0.5 (mL) of liquid methane '''at 90 K (-183C)''', a violent explosion occurred.
** And, and before you get any funny ideas, ''yes''. The crazy bastard that did said experiment also applied Dioxygen Difloride with the above Chlorine Trifloride, something the writer for the article could only respond with "[[FlatWhat say what]]?"
*** So we're clear, this is a substance with the capacity to release the energy equivalent of a hearty breakfast if you get a couple of ''molecules'' of it together and breathe hard in the same room; the only record of any serious experiments attempted with it was by a single scientist in the [[WhatDoYouMeanItWasntMadeOnDrugs sixties]], who soon concluded it was too dangerous to study.
* The parade of chemical flames:
** Acetylene/oxygen flame, a most common and widely used in industry. 3300 C, 6000 F. Melts most materials in your house.
** Atomic hydrogen flame. No need for oxygen. Atomic hydrogen is produced by electric discharge and 'stable' in gas form (fuses into molecules slowly). When directed onto a hard surface, it is catalytically fused back into molecules and produces up to 4000 C. Enough to melt tungsten, but not enough to melt special ceramics, which require about 4500 C to melt.
** Cyanogen/oxygen flame - 4525 C (8180 F). Cyanogen is toxic, but not uncommon in chemistry, so the flame can be produced by any reasonably determined person.
** Dicyanoacetylene/oxygen flame: [[UpToEleven 4990 C (9010 F)]]. Our sun is about 6000 С on its surface and most common kind of stars -- red dwarfs - are cooler -- about 3000 С.
* Of course, in terms of raw energy, it's hard to beat nuclear fusion. It is what stars run on, after all.
** It's astonishing how little power is produced by each cubic meter at the [[http://en.wikipedia.org/wiki/Solar_core center of the sun.]]
** However, there are things that beat it easy. So known gamma-ray bursts are produced when big amounts of matter rush into a black hole at a great rate. The estimated temperature is about 1-10 * 10^9 Kelvin.
*** Actually its amazingly easy to beat mere conventional nuclear fusion. Muon-aided fusion, energy release from matter falling onto degenerate stars (white dwarfs, neutron stars, other more exotic kinds), antimatter annihilation, theoretically the temperatures of evaporating singularities reach really ridiculous levels too.
* High Test Hydrogen Peroxide. When it disassociates at 100% purity you have a roughly 1270 C cloud of steam and oxygen which can be used as rocket fuel all by itself. The disassociation result wants to hypergolicly set fire to anything it can heat up to it's autoignition temperature.
