[[folder:Web Original]]
* ''WebAnimation/DeathBattle'': In "[[Franchise/MortalKombat Goro]] vs. [[Franchise/{{Pokemon}} Machamp]]", Goro sets Machamp on fire and burns it via his fire breath. This only activates Machamp's Guts ability and strengthens it instead.
* The Volume Four opening of ''{{WebAnimation/RWBY}}'' has the heroes facing off against a Geist, an incorporeal Grimm that possesses inanimate objects like boulders to use for a body. When it replaces a blown-away arm with a tree, Ruby crows, "Big mistake!" and opens fire with incendiary ammo. [[IronicEcho "BIG MISTAKE!"]] screams Jaune, as this has simply given the Geist a flaming arm instead.

* In the ''WesternAnimation/FamilyGuy'' episode "Lois Kills Stewie", when Lois assumes Stewie is dead after being caught in an explosion. He's not.
* ''WesternAnimation/PhineasAndFerb'' features this. At the climax of the episode, Isabella, Phineas and Ferb find themselves on the run from a giant colossus made entirely of corn. They cross a rope bridge that hangs precariously over fire and Phineas cuts the rope, causing the giant to fall into the flames below. The victory is extremely short lived because it leaps up from the flame and continues the chase while on fire. The group chides Phineas for this and he responds by telling them he thought the monster would pop due to it being made out of corn.
* When ''WesternAnimation/ElTigre'' had to battle Sartana of the Dead's grandson; Django of The Dead. El Tigre managed to get Django to drop into a lava pit in the final battle, but came back using the lava around his hands and arms to blast himself back onto the platform and use said lava to retaliate. Until he accidentally touched his own guitar with his lava hands and destroyed himself.

* The second episode of ''Series/{{Angel}},'' while fighting a parasitic monster that takes over human bodies, Angel tosses it into a nearby lit burn barrel a bum was using. This was the right thing to do since about it's only weakness is fire, but [[BurnTheUndead Angel shares the same weakness]] and it spends it's last few seconds marching toward him, luckily Kate shoots it enough times to stop it in it's tacks and burn up away from Angel.

* Happens in the 2008 horror film ''Film/{{Mirrors}}''. Makes some sense as [[spoiler: the "villain" Anna is possessed by some sort of otherworldly evil force and hence probably isn't bound by normal human limits.]]

* In the classic ''ComicBook/SpiderMan'' story ''Nothing Stops The Juggernaut'', Spidey tries increasingly destructive methods to stagger the unstoppable X-men foe, culminating with blowing up a tanker truck of gasoline. Juggernaut is unharmed, but now ''on fire''.
* It happens ''again'' in the ''ComicBook/XMen'' issues of ''ComicBook/FearItself'', when Juggernaut is possessed by a godlike being (which means that he's now empowered by ''two gods'' instead of the usual one) and Cyclops rolls out several battle plans to stop him. All are ineffective, but then we get to this:

Sometimes it is just a delayed reaction and the fire will prove fatal, but that is little comfort considering it may prove fatal to the heroes first. Might also apply to NukeEm if the target is gigantic. EldritchAbomination: Bad. Eldritch Abomination that gets nuked, and stands back up pissed off and blazing radioactive fire? Worse.

* In the ''Anime/{{Pokemon}}'' anime, the battle between Ash's Charizard and Blaine's Magmar seems to end with Magmar diving into lava while holding Charizard in a headlock. However, it turns out that being dunked only made Charizard angry when he explodes from the lava with Magmar in tow and proceeds to Seismic Toss him right back into the volcano.

* The ''Series/BabylonFive'' TV movie ''[[Recap/BabylonFiveFilm02Thirdspace Thirdspace]]'' has a scene near the end where a Narn security guard's arm is set ablaze during a brawl. Rather than try to extinguish it, he continues to beat on his opponent.

!!Examples:

[[folder:Video Games]]
* ''VideoGame/AdventureQuest'' has the Razorclaws, wolves transformed by dark magic to act as assassins for their sorcerous masters. They are most vulnerable to fire, but if you are foolish enough to actually use fire on a Razorclaw, it will catch fire and perform a vicious attack on you for serious damage.
* Setting a molotov thrower aflame in ''VideoGame/FarCry3'', either with your own incendiary weapons or by shooting theirs, usually results in having him chase after you on fire until he burns to death.
* ''VideoGame/Borderlands2'' has Krieg the Psycho as a player character version of this. His Hellborn skill tree is all about dealing fire damage and getting buffed when set on fire. He even has a chance to set himself on fire when using incendiary weapons.
* ''VideoGame/AlienIsolation'':
** Using the flamethrower on the alien will at first cause it retreat to the nearest air vent when set on fire. If you happen to be between it and the nearest vent when you lit it aflame, you might just get run over by it in the process. On higher difficulties, using the flamethrower too much will cause it to run straight at you and ignore the fire entirely.
** The Working Joes, being androids, don't even react to being set on fire outside of [[RedEyesTakeWarning becoming hostile]].
--->'''Working Joe:''' [[BadassBoast Only wild animals fear fire.]]
* This significantly reduced the effectiveness of the flamethrower in the FirstPersonShooter ''VideoGame/AliensVsPredator'' for the PC, as setting aliens on fire would simply result in them continuing to attack you while on fire, and since they're already extremely fast attackers, this usually meant you dying [[NintendoHard even more quickly than usual]]. This was adjusted in ''VideoGame/AliensVsPredator2'', where, since Aliens aren't so goddamn fast anymore, the flamethrower kills 'em real good before they can get to you. Worsened in the 2010 game. Not only does it fire kill the aliens too slowly, if they grab you while they're on fire, they have a tendency to explode.
* Fire in ''VideoGame/{{Besiege}}'' is one of the most effective forms of crowd control for groups of enemy soldiers, with the trade-off being that ignited enemies get a solid 10 or so seconds of attacking before dropping dead, all fire-type weapons being short-range, and your contraptions typically ignite easier than toilet paper soaked in gasoline. This can be averted with liberal use of armor plating, or getting the hell out of there after lighting them on fire.
* ''VideoGame/TheBindingOfIsaac''
** Hoppers, once lit ablaze, become "F. Hoppers", which have three times the HP and move faster. What's worse, setting them on fire isn't the player's fault; they get that way by jumping into fires that naturally spawn in the room. The only way to prevent it from happening is to kill, or douse the fires, before they can. And then there are the rooms where said fires are locked off behind rock walls...
** Coal spiders are regular spider enemies that carry a lump of coal on their backs as armor. If they're hit with fire (which tends to be plentiful in the Mines and Ashpit where they're found), the get set ablaze, move faster, and their health increases.
* ''VideoGame/BioShock'': The in-game advertisement for the Incinerate plasmid ends with "Warning: Fire spreads," and it's not just a joke -- anything that is on fire can set other things on fire, due to a clever bit of programming that makes fire particles themselves double as ignition triggers. Even touching a burning corpse will hurt the player, although he is thankfully immune to persistent burning himself. Most {{mook}}s will get distracted and try to find water if lit ablaze, but beware if they run into oil slicks... especially if there happen to be ExplodingBarrels nearby. Big Daddies, meanwhile, are undeterred by fire and [[ImplacableMan will continue to attack]] until one of you goes down. A not-so-clever bit of programming makes it so that they will sometimes aggro in response to non-player-inflicted damage. Set a splicer on fire and then [[SetAMookToKillAMook hypnotize him to attack a Big Daddy]]? That splicer may be the least of your concerns in a moment.
* ''VideoGame/{{Blood}}'' allows you to set zombies on fire, and when they erupt into a zombie torch, they hurt you with touch.
* While the ''VideoGame/{{Bomberman}}'' series more or less revolves around killing everything with fire based explosives, one of the possible skull item effects from Bomberman 64 and Bomberman 64: The Second Attack sets the person unfortunate enough to pick up the item on fire. While in this state, the burning bomber has about 30 seconds to kill everyone else with their burning body (can't use bombs since their body sets off any bombs he drops or touches) before the fire finally kills him.
* ''VideoGame/BlowOut'' have the larger mutant bug enemies who can survive incineration via flamethrower or incendiary grenades, only to continue chasing after you while burning up, where the flames can hurt you on contact.
* Fire burns the vampires bad in ''VideoGame/BuffyTheVampireSlayer''. But not right away. They can still tag you for a nasty burn before dusting.
* ''Burn, Zombie, Burn''. It's pretty much the whole title. Running around lighting zombies on fire makes them faster and deadlier. On the plus side, it increases your score multiplier.
* In ''VideoGame/MarvelVsCapcom 2'', one of Jill Valentine's special moves is a zombie summon. One possible summon is a flaming zombie. Instead of grabbing and holding an opponent in place like normal zombies, [[ActionBomb these explode]].
* A possibility within the VideoGame/NaziZombies mode of ''VideoGame/CallOfDuty: World at War''. While flamethrowers will generally be a good weapon against the zombies for most of the game, it becomes more dangerous later on as they get more health. However, being careful and just running around, lighting zombies aflame and keeping your distance while they burn usually works.
* In ''VideoGame/CastlevaniaPortraitOfRuin'' striking a zombie ([[PaletteSwap or ghoul]]) with a fire attack causes them to become skeletons, even if the attack should've reduced their HP to zero.
* In the ''Fall from Heaven II'' mod for ''VideoGame/{{Civilization}} IV'', which is set in a fantasy world, the [[LegionsOfHell bringers of Apocalypse]], the Sheaim, have an axemen replacement called the Pyre Zombie, which is, well, ExactlyWhatItSaysOnTheTin; A zombie inherently on fire. Of course, whenever one of them perish, all enemy units in the vicinity are damaged, which makes the "PZ" the perfect bane of any army that cannot perform ranged attacks or are somehow immune to fire. To be fair, though, it's one of the only early-game advantages of the Sheaim.
* Happens in one of ''VideoGame/CorpseParty's'' [[NonStandardGameOver Wrong Ends]] when Yoshiki tries to fend off a sentient anatomical model by setting it alight with a Bunsen burner. The model collapses into a pile, then quickly gets back up and kills Yoshiki by embracing him while still on fire.
* In ''VideoGame/CthulhuSavesTheWorld'', in "Cthulhu's Angels" bonus campaign, the boss Evil Bridge, when attacked with fire attacks (like {{Fireball}} spell), catches fire. When on fire, Evil Bridge's damage is increased by 50%, and the bonus stacks the more fire spells are used.
* The Immolation spell in ''VideoGame/DarkSoulsII'' technically transforms ''you'' into this variation, considering you're Undead. It causes gradual damage to everyone that comes near you, but also saps your own HP. The [[DeadWeight Scorcher]] enemies in Brume Tower will also do this if hit with any fire damage, becoming faster and eventually turning into an ActionBomb.
* Shadows in ''VideoGame/DeadlyPremonition'' become extremely fast if set on fire and run straight for York once ablaze. However, they die quickly from the fire, too.
* ''VideoGame/Dishonored2'': Using incendiary attacks on a Clockwork soldier is useless due to its mechanical nature. However, thanks to its wooden components, it will be set on fire, so now there is a giant robot on fire trying to kill you. Strangely enough, you do not seem to be damaged by the flaming frame of the Clockwork soldier.
* ''VideoGame/Doom3'' features a zombie that is already on fire when it attacks you. Ordinary zombies, however, seem abnormally sensitive to fire.
* There is a certain point in ''VideoGame/DragonAgeOrigins'' where you have to protect a village from an oncoming zombie horde. You can find barrels of oil, and suggest to the head of the guard to light it on fire, weakening the initial wave. If Zeveran is in your team at this point, he'll wisely snark that it may create flaming undead, instead. [[SubvertedTrope Subverted]] in that, yes, fire does help against the zombies, with no serious repercussions. Although if you push back the waves, the stupid AI will inevitably kill themselves by walking into the burning oil.
* ''VideoGame/DwarfFortress'':
** Occurred in the LetsPlay ''[[http://fromearth.net/LetsPlay/Boatmurdered/ Boatmurdered]]'' with Sankis -- whose power, if anything, became even more terrifying once he was aflame.
** The fortress' method for dealing with the various goblins invaders, killer elephant herds, and crazed mandrills became "flood everything outside the mountain with lava". [[spoiler:This eventually backfired ''fantastically'' when a puppy got caught in the lava outside and wouldn't stop burning. In itself this would have been fine, but one of the dwarves then decided to go and retrieve the puppy. That dwarf got lit on fire and went back into the fortress, not only igniting random things but also spreading smoke everywhere, which causes insanity. In the wake of this came Sankis's rampage mentioned above, which catalyzed a chain of events which eventually reduced the ''entire'' fortress into a desolate, smoking, miasma-filled ruin. Well, more of one than it already was, anyways....]]
** In general, earlier versions of ''Dwarf Fortress'' had dwarves be generally non-plussed about picking up things on fire and being on fire themselves, which was highly amusing until you realized it made it nearly impossible to keep a fire under control.
** Variant: Butchering a Fire Imp corpse occasionally sprays clouds of boiling fat everywhere, setting anything flammable in the room ablaze.
** Bronze Colossi are not immune to lava, but their large size mean they melt slowly. If the one you just immersed in magma gets out too soon of the trap, it will integrate the heat into its attacks, multiplicating its danger.
* Territorial Oaks in ''VideoGame/EarthBound1994'' are a special kind of evil: Not only do they burst into flames automatically when you kill them through ''any'' means, but this deals instant damage in the ''hundreds'', which you can only survive if you have enough HP left for the rolling health meter to stop before you leave the battle screen. Did we mention that your maximum HP at the point where you start to encounter them is likely to be in the ballpark of 150?
* In ''VideoGame/TheElderScrollsVSkyrim'', any mook set on fire will continue to attack (though thankfully they won't set you on fire) -- in fact, you [[YouHaveResearchedBreathing have to get a specific high-level perk]] to make enemies flee when they're at low health and on fire.
* The boss of the Iifa Tree in ''VideoGame/FinalFantasyIX'', the Soulcage isn't very tough, and given that it's both wood-based ''and'' undead, you wouldn't be wrong in surmising that it's weak to [[KillItWithFire fire]]. Setting it ablaze will result in it catching fire and attacking with Fire Blades, a hard hitting [[HerdHittingAttack party attack]]. The flaming status can be canceled by an ice-elemental attack. Of course, given that it's an undead monster in a Final Fantasy game, [[ReviveKillsZombie there's a certain shortcut...]]
* ''VideoGame/GearsOfWar'' gives us the Berserkers, 10' tall female Locust with nothing but murder and anger on their minds and an armoured hide resilient to bullets. Setting them on fire makes their hide vulnerable, however it also makes them even angrier, allowing them to charge and swing their fists at double speed.
* In ''VideoGame/HauntingGround'', following the final boss battle, Fiona manages to [[spoiler:push Lorenzo into a pit of lava. For a moment, she thinks she's finally killed him, until he claws his way out, now a flaming skeleton with a [[TouchOfDeath Touch of Death]].]]
* The ''VideoGame/GrandTheftAuto'' games let you have some fun with this. Touching fire lights you on fire, but it generally isn't enough to kill you if you have enough health, leaving you with the option to walk into people and set them on fire. Several of the games allow the player to become immune to fire-damage by completing the Fire Fighter minigame. Like the Saints Row example above, this makes using fire based weapons like the Flamethrower or Molotov Cocktails a much more viable option for causing mayhem without significant risk of burning oneself to death in the process.
* In ''VideoGame/HalfLife2'', while regular headcrab zombies will scream and hold their arms out in agony when on fire, fast zombies don't even notice, right up until the point where they fall down and die from it. The fire doesn't do any additional damage to you, though. Poison zombies also seem to be oblivious to the flames when set on fire. Incidentally, burning, legless ZombieMooks [[ZombieGait dragging themselves along the ground towards you]], while what's left of the ZombieInfectee screams in terrified agony through a FaceFullOfAlienWingWong...
* ''Franchise/{{Halo}}'': In ''VideoGame/Halo3'', using fire against the Flood can sometimes lead to this. Sticky grenades [[OhCrap have a similar effect]] in all the games. Subverted completely with the Pure Form Flood, as they die near instantly from Firebomb grenades or the Flamethrower and it's even the ''recommended'' way to deal with them in the official StrategyGuide (the fact that most levels with high concentrations of them often gives you a Flamethrower or two in conspicuous spots should also be a hint).
* In ''VideoGame/HorizonZeroDawn'' and ''VideoGame/HorizonForbiddenWest'', it can be tempting to try setting a [[BearsAreBadNews Frostclaw]] on fire due to them being listed as having vulnerability to fire damge. Try it and they'll use their Frost abilities to immediately put the fire out, then come after you with claws that are now charged with Frost for extra damage.
* In the original ''VideoGame/KingdomHeartsI'', it's possible to set [[WesternAnimation/PeterPan Captain Hook's]] pants on fire if you light him up with a Fira spell. However, he could damage you by flying into you as he's bouncing around his ship to get the fire out.
* In ''VideoGame/KingdomOfLoathing'', this happens when your nemesis goes OneWingedAngel by invoking a revenge demon immediately before falling into lava.
* ''VideoGame/Left4Dead'':
** Generally speaking, setting the zombies on fire is a very good idea... but the Hunter, although the flames will kill him eventually, gets a ''huge'' boost to his attack power while on fire. Said boost was later {{nerf}}ed by a patch (and only applies if the survivors set them on fire directly with Molotovs, gas cans or incendiary ammo instead of the Hunter intentionally lighting himself with pre-existing flames in the map), but it's still present.
** The Boomer doesn't directly react being set on fire, but because it gradually wears down his health, it turns him into a walking time bomb, able to explode in the vicinity of the survivors even if they avoid shooting him and try shoving him away.
** The Witch doesn't like fire either: normally, she'll leave you alone if you're not the one who [[SavageSetpiece pissed her off]], even if you're shooting her. Set her on fire, however, and you'll be her one target no matter what. Thankfully, a burning Witch is also slower than a regular one, and only has to be evaded for 15 seconds before she dies.
** Finally, in Campaign mode for the first game, the Tank gains a tremendous speed boost when lit on fire in exchange for an exact countdown (not related to his health) until his death. In Versus multiplayer and on all modes of the sequel, however, it's treated as DamageOverTime, and each tic of damage breaks his gait, so fire ends up slowing him down.
* ''Franchise/TheLegendOfZelda'':
** The [[GoddamnedBats Keese]] are generally invulnerable to straight-up fire attacks. This, in fact, usually sets them on fire, turning them into the far more dangerous Fire Keese.
*** In the ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Seasons/Ages]]'' games, Fire Keese not only do more damage but can also fly above Link's sword's reach.
*** In an inversion, Keese hit by a cold- or ice-based weapon turn into Ice Keese, becoming shrouded in freezing mist rather than flames but otherwise acting much the same as Fire Keese do.
** In the handheld games, setting a [[{{Mummy}} Gibdo on fire]] is a mixed bag, as the wrapping burns away to reveal a faster-moving, hopping Stalfos, who's harder to hit but takes far less damage to defeat. Probably worth it near the beginning of the game, when your dinky starting sword takes like 8 or 10 hits to defeat a Gibdo; perhaps not so much later.
** Ask any player about what happens when they accidentally got too close to a Gibdos or [=ReDead=] in the 3D games after using a fire arrow but before the arrow finishes them off.
** In Breath of the Wild, enemy weapons can catch fire and light you on fire. Fire attacks and explosions will allow opponents to burn you.
* The Ents in ''Literature/TheLordOfTheRings: VideoGame/TheBattleForMiddleEarth'' are normally slow and tough, but when set aflame they become enraged, moving and attacking much more quickly, while taking damage over time from the fire. After a few moments of rampaging they'll try to find some water to douse the flames. Mûmakil also rampage when set alight, though there's no way to extinguish the fire and they'll eventually die.
* In ''VideoGame/{{Minecraft}}'', flaming zombies will burn the player when attacking. Becomes even scarier when you realize that sunlight naturally lights them on fire.
* Could be good or bad in ''[[VideoGame/OgreBattle Ogre Battle 64]]'', depending on who you did it to and your outlook. Setting a Zombie on fire would cause them to pull a terminator-like transformation into a Skeleton. Happened both to enemy Zombies and your own Zombies. Skeletons were generally better than Zombies, but it was a huge pain to create them.
* Ignus from ''VideoGame/PlanescapeTorment'' is permanently on fire as a result of the collective hedge wizards in the Hive opening a portal to the elemental plane of fire ''inside his body'' and turning him into a living effigy as a way of punishing him for an act of mass arson. As a punishment, [[{{Unishment}} it failed miserably]] -- it only made him ''[[PyroManiac happy]]''.
* ''{{Franchise/Pokemon}}'':
** The Abilities Guts and Flare Boost can grant the user a 50% boost to their Attack or Special Attack (respectively) while they're afflicted with the Burn status effect. Flare Boost is the more straight example as it only activates in response to the user being Burned, while Guts can also activate when it's Poisoned or Paralyzed. Notably, Guts also ignores the usual 50% Attack reduction from a Pokemon affected by Burn, meaning that it gets stronger instead of weaker when set on fire.
** Pokémon with Flash Fire are not only immune to Fire type moves (including the status inducing Will-O-Wisp), it also fuels their Fire type attacks by 50%.
* In the expansion pack of ''VideoGame/Postal2'', Apocalypse Weekend, setting zombies on fire is about as effective as dousing them in lemon juice. Actually, it's even less effective, as the fire will do nothing (these zombies [[YourHeadAsplode require their heads to be destroyed before they'll stop attacking]]), and unless you cut their legs off beforehand, they'll just run up to you and set ''you'' on fire too.
** Setting people on fire who are already aggressive towards you will often result in them running blindly in your direction and setting you on fire as well before you can back away, due to the short throwing arc of your matches. The random pathing of a burning NPC makes it even harder to avoid getting caught on fire by a passing burning protestor.
* In ''VideoGame/PrinceOfPersia2008'', the main characters knock a giant warrior king off the edge of a tall tower, and he falls into a pool of black ooze. When the tower falls apart and the they land on a lower platform, the creature crawls from the ooze, [[https://www.youtube.com/watch?v=1-L-5XzphKM scaling the wall by force.]] The title prince's response?
-->'''Prince:''' Oh ''good'', now he's on fire.
* In ''VideoGame/{{The Punisher|THQ}}'', setting mooks aflame with the flamethrower isn't one hundred percent effective; they panic and run amok, sometimes into you. Ouch.
* ''VideoGame/ResidentEvil4'':
** The game has both the Incendiary Grenades, which avert the trope and merely cause painful burning, and a single unique [[NightOfTheLivingMooks Ganado]] nicknamed 'Oven Man' that [[ExactlyWhatItSaysOnTheTin escapes from an oven while on fire to menace the player]]. No one seems to be quite sure what he was doing in there.
** Before fighting the Village Elder, Leon shoots an [[ExplodingBarrels explosive barrel]], setting him and the barn they're both locked inside on fire. This doesn't so much kill him as make him [[OneWingedAngel reveal his terrible true form]].
* It works even worse for the player in ''VideoGame/ReturnToCastleWolfenstein'': While flame works well against the sword'n'shield zombies, it turns the unarmed ghost-skull ones into mean firebreathing mofos.
** Their ''VideoGame/{{Wolfenstein|2009}}'' successors, the Despoiled, are constantly engulfed in magical fire ''from the start''. Naturally, it's not a good idea to get too close to them. And, they're quite immune to the flamethrower.
* A serious threat in ''VideoGame/SaintsRow''. Burning people can set other people on fire, and burning cars explode, scattering burning debris which can also set people on fire. The zombie homie you can summon is rather nonchalant about being lit ablaze. Potentially dangerous to you, certainly dangerous to your enemies.
* ''VideoGame/SaintsRow2'' has a damn minigame focused around this. You're driving an ATV while on fire and your job is to light as many people on fire as you can. The player character is wearing a fireproof suit for the duration though (which can be unlocked for general use by completing all levels of the minigame). The third game allows the player to purchase immunity to fire as an upgrade, allowing quite a bit of fun with flame based weapons with little risk to the player.
** While this trope applies to every ''VideoGame/SaintsRow'' game since touching a flaming enemy will catch you on fire, it is especially notable in ''VideoGame/SaintsRowTheThird'' with the Decker Specialists, women with high tech skates that allow them to move extremely fast. When a normal enemy is set on fire, they run around aimlessly, and the same thing applies with the specialists, only at [[OhCrap super speed]].
* In the original ''VideoGame/SyphonFilter'', in stages where a lot is burning, there will be some mooks, [[ManOnFire on fire]], running [[strike: wildly]] to ''you''! Since you'll die instantly if caught on fire, the best option (andv only, actually), is to put said mook out of his misery.
* ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'': The final battle. What is cooler than [[spoiler:a badass DualWielding a sword and axe? A badass DualWielding a sword and axe who is ''on fire''.]]
* In ''VideoGame/TeamFortress2'', the soldier achievement Semper Fry requires you to kill opponents while on fire. To explain, on of the Soldier's melee weapons, the Equalizer, increases his speed and attack when he is at little health. So more damage = more power. Fire = more damage. Fire = more power.
* Done to hilarious effect in ''VideoGame/TimeSplitters''. Hell, there is even a game-mode based around it! (Virus) One person starts on fire and must find and light everyone else on fire. Also, it burns away armor only first, then health. If you know where all the pickups are, in deathmatches you can continue to collect kills for a long while if you don't get hit too much, just by running into people and shooting them as they try and flee and find an extinguisher. Also everyone has hilarious screams while on fire, so you may as well do it anyway!
* ''VideoGame/TurboOverkill'' grants you a double-barreled flamethrower which kills regular enemies instantly. However, the GiantMook opponents ''will'' try leaping on you while alight - stay out of their reach or you'll be badly scorched.
* The Flamers in ''VideoGame/{{Unturned}}'' are zombies that are naturally on fire[[note]]they can even be seen from far away at night due to the light produced by the fire effect[[/note]]. They're no different from regular zombies in behavior or stats, except [[ActionBomb they explode in a massive fireball when they die]] that hurts ''a ton'' and ''turns any zombie within the blast radius into another Flamer''. They're one of the main reasons for a player to collect and use ranged weaponry.
* ''VideoGame/VampireTheMasqueradeBloodlines'' has the Grout's Mansion level, where you have to find a lost vampire primogen who was studying madness. And of course, he has a lot of human test subjects. When you arrive at the mansion, you will soon realize that all this madmen have somehow been able to free themselves and aren't exactly happy to see you. So, after you punched, shot and sliced your way through the mansion, you come across a vampire hunter, who sets the whole place on fire. And also, it seems like some of the test subjects have survived your fights in the mansion and now are on fire as well. And instead of running out of the mansion (they are insane after all) they decide to try killing you again. They are much more vulnerable now, it usually takes only two shots to kill them. However, considering that vampires are very vulnerable to fire, they can also take out ''you'' with two hits. It's helpful to have [[MoreDakka a machine gun]] when these guys approach you.
* ''VideoGame/VivaCaligula'' has two major {{gamebreaker}}s: [[KillItWithFire the flambeau]], and [[NightOfTheLivingMooks Necromancy]]. Combine the two: Your own personal army of flaming skeletons! The fire doesn't bother the undead, but any living enemy they touch will burst into flames, steadily draining their health until they collapse, at which point you can add another skeleton to your army.

* ''Literature/AHerosWar'': Banage tries to destroy the zombie horde threatening his village, by crashing flaming carts into them as they charge. Unfortunately, while the zombies' dead flesh ''is'' highly flammable, they aren't bothered or even slowed by it, meaning that they crash into the village's (wooden) walls and gates while on fire, causing tremendous damage. The fire does eventually kill them, but too slowly to be worth it.

* ''VideoGame/BioShock'': The in-game advertisement for the Incinerate plasmid ends with "Warning: Fire spreads," and it's not just a joke -- anything that is on fire can set other things on fire, due to a clever bit of programming that makes fire particles themselves double as ignition triggers. Even touching a burning corpse will hurt the player, although he is thankfully immune to persistent burning himself. Most {{mook}}s will get distracted and try to find water if lit ablaze, but beware if they run into oil slicks... especially if there happen to be ExplodingBarrels nearby. Big Daddies, meanwhile, are undeterred by fire and [[ImplacableMan will continue to attack]] until one of you goes down. A not-so-clever bit of programming makes it so that they will sometimes aggro in response to non-player-inflicted damage. Set a splicer on fire and then [[SetAMookToKillAMook hypnotize him to attack a Big Daddy]]? That splicer may be the least of your concerns in a moment. attacks or are somehow immune to fire. To be fair, though, it's one of the only early-game advantages of the Sheaim.

* In the ''Fall from Heaven II'' mod for ''VideoGame/{{Civilization}} IV'', which is set in a fantasy world, the [[LegionsOfHell bringers of Apocalypse]], the Sheaim, have an axemen replacement called the Pyre Zombie, which is, well, ExactlyWhatItSaysOnTheTin; A zombie inherently on fire. Of course, whenever one of them perish, all enemy units in the vicinity are damaged, which makes the "PZ" the perfect bane of any army that cannot perform ranged
