[[caption-width-right:258:What part of "[[ExactWords anywhere]]" did you not understand?]]

->''"Did you know I can create a force field inside someone's body and expand it until they explode?"''
-->-- '''Susan Storm''', ''Film/FantasticFourRiseOfTheSilverSurfer''

There's oodles of different kinds of powers, some lethal and some harmless. Having obviously lethal powers has remarkably many downsides. BadPowersBadPeople means the owners can't use them at all [[IfYouKillHimYouWillBeJustLikeHim for fear of becoming killers]], they tend to [[InverseLawOfUtilityAndLethality miss a lot when aimed at heroes]], and [[TheDarkArts they tend to corrupt]] or [[PowerDegeneration slowly kill them]] anyway. This can make the "wimps" with the [[WhatKindOfLamePowerIsHeartAnyway power of Heart]] become [[HeartIsAnAwesomePower surprisingly useful]] by using their "harmless" powers in [[WhenAllYouHaveIsAHammer surprisingly]] creative ways.

One of which is using said harmless power in a horrifyingly lethal way.

Turns out the kid with a GreenThumb can make the local flora [[GardenOfEvil emit toxic pollen]], the BarrierWarrior just needs to tilt her barrier to [[PortalCut use it as a knife]], or the person who can create love can also create fear so powerful it makes people's hearts explode, or the WhiteMage with HealingHands can reverse her ability to [[TouchOfDeath rapidly]] drain LifeEnergy, or worse, heal too much and give the victim [[{{Deadpool}} horrible cancer]]. Other times, the power itself always had the lethal applications, such as PsychicSurgery being used not to take bullets out of a person, but to ''put them in... '''by hand'''''. However, the character had a self imposed DramaPreservingHandicap in the form of MindOverManners or NonLethalWarfare to [[IfYouKillHimYouWillBeJustLikeHim avoid becoming a villain]].

But eventually, these heroes will face a situation that crosses the GodzillaThreshold. Maybe their life or the life of a loved one is at stake, or a villain just [[BerserkButton pushed their buttons]] [[DeadSidekick in the worst]] possible way and forces them to use lethal force. And [[IAmNotLeftHanded then the gloves come off]].

It goes without saying that this is DarkerAndEdgier stuff, and in generally light series a hero forced to use the lethal applications of their abilities will probably enter a HeroicBSOD even if they ''don't'' kill an enemy. Some heroes who do a lot of thinking on their powers will usually realize they can do this and get very, ''very'' scared of the potential horror should the InstantAllegianceArtifact, MirrorMoralityMachine, (or plain old life) make them do a FaceHeelTurn. This doesn't mean they won't ever use this [[JustThinkOfThePotential potential application]]; they can use it to threaten enemies as the above quote shows.

This causes a related phenomenon -- villains very rarely get the powers that can be abused in this way specifically for this reason. When they do, they become GoodPowersBadPeople.

Compare DangerousForbiddenTechnique and RequiredSecondaryPowers. May cause viewers to decide that HeartIsAnAwesomePower. Contrast the InverseLawOfComplexityToPower. Similar to LethalJokeItem, in that neither are taken seriously until their lethality is revealed. Often an aspect of a SemanticSuperpower.



[[folder:Anime & Manga]]
* Maka of ''Manga/SoulEater'' has the power to ''not'' be insane. When combined with her weapon's ability to imagine playing the piano and actually create music, the two can combat insane villains by playing music fused with AntiMagic. They use this many times throughout the series. In a more benevolent and nonlethal use, she also serves as an anchor point for her friends to remain grounded when they synchronize their souls and they have to dip into madness for a power boost.
* In ''Manga/PleaseSaveMyEarth'' Mokuren's GreenThumb powers seem pretty limited to making plants grow or die quicker than normal by her ''singing''. Yeah, it's not instantly lethal to anyone. But killing all the plants on a planet (or even ecosystem) is deadly in the [[GreenAesop long run]]. Not to mention that plants growing out of control overnight is pretty scary too. And if you live in a space station with nothin' but vacuum outside...
* ''Manga/OnePiece'' is full of this. In general, power sets in ''One Piece'' have a specific theme, but the sky's the limit with how one can use those powers, given enough experience with them. Devil Fruit powers canonically don't get stronger; their users just get more creative with them. One of the things this series is known for is its incredibly pragmatic use of weird and otherwise useless powers.
** The protagonist, Monkey D. Luffy, can stretch like rubber, which also allows him to pump his blood at speeds that would burst a normal person's heart, giving him an enormous boost in speed and strength. Later it allows him to pump other parts of his body around such as bones and muscle, which ups his attacking power immensely to the point he can basically turn his limbs into air-pressure cannons and fire his fists/feet at deadly speed.
** Nico Robin's Flower-Flower fruit gives her the power to sprout new limbs like flower petals. Thing is, they don't have to be attached to her body. Does her opponent have a neck? *snap* She can also create large groups of a single limb working together, essentially creating giant hands and feet or even short-lasting wings. By Fishman Island she learns the ability to duplicate herself entirely.
** Bartholomew Kuma has the power to push. He uses it for pushing people around half the planet, pushing himself to FlashStep, pushing air together to make a bomb or ''pushing pain away'' (into other people).
** Kaku can turn into a giraffe, who makes use of his elongated neck to gain more momentum for his strikes and puts his elongated limbs to work by enhancing his strikes' power and reach; RazorWind that could previously cut a man in half now can bisect entire buildings. Blueno can make portals and doors on any surface, including his combatants' faces.
** Emporio Ivankov can control and inject hormones, which can rapidly overwhelm and overload victims, change their genders in an instant (which is enough of a surprise to incapacitate just about everyone), heal anyone with the HeroicWillpower to power through it and generally engineer the human body to his whim, including his own.
** Buffalo can rapidly rotate any part of his body he wants, allowing him to fly using his dreadlocks as propellers and granting him devastating wind-up punches.
** Diamante has the ability to make things flat like a flag. He uses this to do things like wear a cape made of a steel block that can be rehardened as a shield, make his sword wavy to attack from different angles, or fold up an entire club for easy storage.
** Rocinante can make certain areas completely silent, as well as cause objects and people to be completely silent. It turns out that he is unparalleled in taking out entire groups of people and destroying buildings without anyone noticing, as projectiles from firearms will also be totally quiet, as are people's screams when shot.
** Doflamingo's power revolves around strings. Sounds lame, but in practice these strings are sharp enough to slice through almost anything, and its strength can go up to 'utterly unbreakable' with the Birdcage technique. Even worse, he can attach these strings and forcefully take control of someone else's body. He can even utilize the strings for SelfSurgery, patching up wounds that would otherwise kill him in short time.
** The villain from 10th movie, Shiki, has ability to levitate matter. He uses it to create giant lion heads by lifting masses of ground or water and ram them into enemies.
** [[spoiler:Cracker]] has the ability to generate an unlimited amount of biscuits and, thanks to this power, has amassed a bounty of 860 million Berries. He was able to achieve this destructive power by creating a limitless army of biscuit soldiers--any adversaries he couldn't defeat through brute force, he defeated through attrition. [[spoiler:At least until he challenged Luffy, who, as a BigEater, chomped through his biscuits faster than he could generate them once they figured out they could soften them with water.]]
** The Big Mom pirates have multiple candy generators like the one above, be it Paramecia or Logia, and they are all obscenely dangerous thanks to the properties they can imbue their materials with and the tricks they can pull with them. Whipped cream can become so sweet as to be dangerously caustic, candy can act as both armor, sharp armament and prison, and mochi quickly becomes one of the most dangerous substances in the series thanks to the strongest antagonist in the Whole Cake Island arc.
* ''Anime/DarkerThanBlack'' just generally likes this trope:
** There's one teleporter who liked [[{{Telefrag}} exchanging the positions of random rocks]] [[BeatStillMyHeart and other people's hearts]].
** The show even managed to make "make it rain" directly lethal in the second season, when someone with SuperSpeed got a rather fatal [[InertiaIsAHarshMistress physics]] [[TooFastToStop lesson]]. That's aside from using it to create spheres of water around peoples heads so they drown.
* Raquell from ''LightNovel/ScrappedPrincess'' has plenty of offensive spells, but during one fight in a cave she couldn't use them because she had to use a shield to keep her allies safe. Just as her enemy started mocking her about it she expanded the shield to cover nearly the entire cave. The enemy surrendered just seconds before his head was crushed between the shield and the wall.
* ''Manhwa/{{Yureka}}'':
** High-level player Roto knows a low-level shield spell which is too weak to block any of the magic he normally faces. Except that he can still use it to cast offensive spells on ''himself'' and deflect them at enemies, and [[OutsideTheBoxTactic a spell that's already been reflected can't be stopped by any kind of shield]]...
** Later in the story he defeats a hacker with SuperSpeed [[OutsideTheBoxTactic by casting a "haste" spell on him]], making him TooFastToStop. Both of these strategies are copied and used by other characters (the shield trick was broadcast on national television, while the haste trick was common knowledge among denizens of the Dragon Lands).
** Roto does this again by casting a "berserk" spell on ''one of his allies''... [[TeachHimAnger who dislikes hurting people but has absurdly high stats]].
* ''Manga/JoJosBizarreAdventure'' is frequently made of this trope from part 3 on. Seemingly harmless Stand powers, like healing or being able to turn into string, become incredibly lethal in the hands of a Joestar or one of their allies or enemies.
** Case in point: Lovers, one of the early tarot-themed Stands. It is microscopic and can only exert force proportional to that. But it can enter people's brains and attack essential neural pathways, causing excruciating pain and disabling damage. And since direct power and range are inversely proportional as a standard rule, its user can stay safely away in the other end of town while this happens.
** Josuke Higashikata's Crazy Diamond has the power to "fix", which often takes the form of healing others' wounds (he can't use Crazy Diamond on himself). He is first shown using it to punch ''[[ShootTheHostage through]]'' a hostage in order to grab the hostage-taker's knife and shove it into his chest cavity, and then quickly heal both of them so fast that the hostage didn't even have time to feel pain, ''[[BatmanGambit and]]'' the criminal needed immediate medical attention to remove the knife, which means that he won't be able to escape the police. He later [[FateWorseThanDeath melds a serial killer's body with a huge rock, trapping him inside it forever]], and reforms a glass bottle around someone's hand, severing it from their body.
** In a similar fashion, part 5's Giorno Giovanna possesses the stand Gold Experience, which has the power to "imbue life" into an object by touching it (such as turning a brick into a snake, for example). While this seems useless and he generally uses it to heal his teammates, if Gold Experience punches a person, the overload of life energy makes their mind accelerate to such a speed that their body can't even keep up, leaving them helpless as their face gets punched in for what feels like an infinity.
** Part 8's Tamaki Damo has the ability Vitamin C, which makes other people's body's soft as putty. He then [[spoiler:slices them apart with a folded up banknote while they're still alive, and destroys their vital organs while they melt into a puddle of goo]].
* Much like ''[=JoJo=]'s Bizarre Adventure'', ''Manga/HunterXHunter'' also makes constant use of this trope.
** The most famous example of this is Hisoka, who usually [[NoKillLikeOverkill overkills]] his opponents using the power of chewing gum. That's not using chewing gum as a weapon, his ability is ''literally'' making his energy stretchy and sticky. He also has the ability to affect the texture of flat objects. Even his [[ProfessionalKillers Gene Ryodan]] allies thinks this is only useful for show... until he used it to falsify a document that can prove his guilt, making him look innocent. And on the job, he can falsify his Gene Ryodan tattoo (which is a proof of membership) so he can move undetected while not doing his job.
** The main character, Gon, [[CallingYourAttacks calls out his signature moves]] before doing them. Unlike most shonen series, this is a liability in ''Hunter X Hunter'', as it telegraphs what the user is going to do. Gon is fully aware of this drawback and takes advantage of it by deliberately ''miscalling'' his attacks so his opponents expect one thing but he attacks with another.
* ''Franchise/{{Naruto}}'':
** The [[TheMedic medical ninjutsu]] can be put to astonishingly lethal uses, like creating a chakra scalpel that cuts right through subcostals and important blood vessels while leaving the skin intact. Even the basic healing touch ability can, if used unskillfully or deliberately wrong, mess up a person's body in unspecified nasty ways, no doubt involving your cytoplasm turning into lethal poison.
** This is kind of how Gaara's power feels when you try to describe it outside the context of the show. "He has telekinetic control over sand." "Well, that's...kind of useful, I guess, what does he do, make roads in the desert--[[RainOfBlood HOLY]] [[PersonOfMassDestruction SHIT.]]"
** Pain's Deva Path's primary ability is to push and pull his targets away or towards him. Its targets include non-concrete objects such as [[{{Hellfire}} Amaterasu]]. And at high enough power, [[spoiler:it was able to destroy the entire Konoha village in ''one'' blow.]] He can also create a manifestation of his "pull" power outside of his own body. Ergo, he can basically create an artificial black hole.
** The Animal Path Pain, besides summoning [[{{Kaiju}} enormous monsters]] that can easily knock down buildings, is rather strategic with ''where'' it summons them. In a fight against one of the ANBU ninja, it places a summoning seal ''on the ninja's stomach'', impaling him on the beak of the giant bird that is subsequently summoned.
* One of the deadlier members of the Noah family in ''Manga/DGrayMan'', Tyki Mikk, has powers similar to [[ComicBook/XMen Shadowcat]] mentioned below. Being a villain, he uses them to rip out organs.
* ''Manga/{{Bleach}}'': Orihime's shielding powers, given one can split a target in half. In Chapter 449, [[spoiler: she revealed she's learned how to use her defensive shield to turn her attacker's power into something that not only turns back onto its originator, but which also ''detonates'' on that attacker like a bomb.]]
** Her healing abilities reject events, which is why she can regenerate missing limbs. Its implied that if she kept going, she could ''erase your existence''.
* ''Anime/PuellaMagiMadokaMagica'':
** The only powers bestowed on [[spoiler: pre-GroundhogDayLoop Homura]] were a sort of HammerSpace and temporary TimeStop — pretty amazing stuff, but not very useful for giving [[TheKlutz klutzy]] NewMeat like her enough direct offensive punch to be useful in combat compared with the other {{Magical Girl}}s. So, she cobbles together homemade pipe bombs from recipes on the web, to use as improvised grenades stowed in her HyperspaceArsenal… Then she starts teaching herself how to shoot with guns she stole using her timestop powers… By the finale, she's trained so heavily and stowed away so much firepower, she could shame a [[MoreDakka LARGE army]].
** If you think about it, Mami is kinda like this, too. By WordOfGod, her only ability is... [[WhatKindOfLamePowerIsHeartAnyway to make ribbons.]] No guns, no bullets, just ribbons. HOWEVER, also by WordOfGod, she was in MagicalGirl business since as young as 13 years old. How? Well, AintNoRule [[GreenLanternRing that she couldn't shape ribbons in a way that can shoot magical bullets, also made of specially made ribbons.]] One engineering lesson later.... [[spoiler: [[Anime/PuellaMagiMadokaMagicaTheMovieRebellion Also,]] AintNoRule She can't make [[HyperspaceArsenal anything,]] ''[[MoreDakka anything,]]'' from ribbons, including a [[MesACrowd functional copy of herself.]] She's basically [[GreenLantern John]] [[TheEngineer Stewart]] if he was a MagicalGirl.]]
* In ''Manga/BrynhildrInTheDarkness'', one character openly asks how someone with the ability to change places with anything could kill someone. The other responds by stating how she could jump off a cliff and switch places with her target so they plummet to the ground.
* In ''Manga/ZatchBell'', Kanchome's powers at the start include Poruk, which transforms him into various objects(but he retains his personal strength no matter how he changes shape), Koporuk, which makes him a few inches tall, and Dikaporuk, which makes a two story illusion of him. He's so weak that he offers absolutely no offensive power in the Belugim EO fight, resulting in [[spoiler:Kid getting sent back to the Demon World]]. Come the end of the manga however, he is one of the first to learn a Shin-level Spell, Shin Poruk... [[spoiler:Which allows him to RESHAPE REALITY IN AN AREA AROUND HIMSELF - that single spell with a few days worth of training was SO POWERFUL he was able to beat Zatch in a hard sparring match without taking ANY damage, easily nullifying Bao Zakeruga and breaking down into happy tears at how strong he's become... illusions aren't just for show, you know.]]
* The [[BigBad Black King]] in ''Manga/{{Drifters}}'' can magically heal and regenerate cellular growth in an aversion of NoCureForEvil. He can also overclock cell regeneration to cause BodyHorror cancerous tumors to burst from one's body. (He does this to humble the Bronze Dragon.)
* [[NonActionGuy Yuuno Scrya]] from ''Anime/MagicalGirlLyricalNanoha'' can ram those [[BarrierWarrior shields]] into your face. Those chains can [[RazorFloss cut you]]. His [[WeaponizedTeleportation teleportation]] [[TeleFrag does not require consent]]. And because of his [[PsychicPowers sensors]], [[OhCrap you can't hide from him]]. The only reason we don't see Yuuno fight more is because [[ActualPacifist he doesn't like killing]], and all of his combat options that are more powerful than a basic ShieldBash are ''incredibly lethal''.
* Telekinesis exists in the world of ''Manga/{{Gantz}}'', but it's extremely weak compared to much of fiction. A common early training exercise is manipulating ''dust motes'' in the air, and it doesn't scale up much from there. Fortunately, it doesn't take much telekinetic futzing about in the brain to cause a lethal aneurysm.
* Ban from ''Manga/TheSevenDeadlySins'' has ability to snatch things from people. This, despite sounding harmless, allows him to take from person whatever he wants -- including body parts or internal organs, which he uses to dismember opponent from a distance.
* In her solo series ''Manga/CodenameSailorV'', [[Manga/SailorMoon Sailor Venus]] shows the power of summoning the stinking atmosphere of Venus. When she does it she only stuns a group of youmas, but one look at [[https://en.wikipedia.org/wiki/Atmosphere_of_Venus what Venus's atmosphere is actually made of]]...
* ''Anime/DanganRonpa3'' occasionally explores some of the more harmful applications of the more mundane-looking Ultimate Talents of Hope's Peak. For instance, the Ultimate Animator admits to incorporating brainwashing techniques to invoke emotion in the viewers of his anime, [[spoiler:and the BigBad exploits this to create a brainwashing video to drive the world to despair]].

[[folder:Comic Books]]
* ''Franchise/XMen'':
** Nightcrawler:
*** He has mentioned many times that he could use his teleport power to PortalCut people but he has never done it... at least not in the main continuity.
*** Well, Nightcrawler did do it to a Sentinel once. Of course a Sentinel 1) [[WhatMeasureIsANonHuman is a robot, not a person]], and 2) has a learning capability so he couldn't do it again.
*** In one alternate continuity story, he ended up taking someone's [[{{Fingore}} fingers]] with him when he jumped.
*** In the ''ComicBook/AgeOfApocalypse'' storyline, that universe's Nightcrawler teleported Wade's, [[spoiler:aka ''[=AoA=]'' timeline Deadpool]] head off.
*** There was also one in continuity story where he removed a [[PowerFist hi-tech glove]] off the Red Skull by holding onto it and teleporting...and took all the flesh off the Skull's hand with it leaving nothing but bone.
*** A much simpler, but effective strategy allowed Nightcrawler to defeat Omega Red, who was giving both [[TheBerserker Wolverine]] and [[ChromeChampion Colossus]] a hard time. He simply teleported Omega Red ''really'' high up and let him fall to the ground. Take note that Omega Red is functionally MadeOfIron; if Nightcrawler did it to someone any less durable...
*** Also since 'porting is usually uncomfortable and nauseating to those not used to it he'll also grab someone and quickly and repeatedly port them until they pass out.
*** It gets taken to a whole new extreme in ''[[ComicBook/XForce Uncanny XForce]]'', where ComicBook/AgeOfApocalypse Nightcrawler kills Blob by [[spoiler: teleporting a ''live shark'' into his stomach]].
*** It's also been suggested that he could just ''leave'' them in the dimension he travels through when he teleports if he bothered to learn how. This dimension by the way [[spoiler:is Hell, literally]]; that's why being teleported by Nightcrawler is an unpleasant experience.
** [[ComicBook/KittyPryde Shadowcat]]:
*** Once, when [[BodyHorror Marrow's bone-growing powers were going out of control]], Shadowcat used her ability to pass through matter to pull her out of the gnarled mass of bone. Marrow wondered aloud how she could've done it, since the bones were still part of her body, and Shadowcat mentioned that, [[ThouShaltNotKill were she so inclined]], she could pluck vital organs out of people's chests.
*** In a 2010 WhatIf One-Shot comic, Kitty does exactly that, stopping a possessed Emma Frost by pulling out her heart while the latter is halfway through transforming into her invincible diamond form.
*** In another WhatIf issue, Kitty sorrowfully {{Mercy Kill}}ed a BrainwashedAndCrazy ComicBook/{{Wolverine}} by leaving her severed hand lodged in his brain.
*** Noting also that Shadowcat, were she so inclined, can also ''leave'' a person behind as she's going with them through something solid. She's made the threat various times.She actually does this to the Hulk once, though Hulk being Hulk, it only stops him temporarily.
*** In the Magik miniseries, the alternate version of Shadowcat defeats the alternate version of Nightcrawler in a sword fight... by ''leaving her sword in his leg''.
*** An alternate Kitty Pryde in Exiles killed an evil, alternate Wolverine by pulling his claws from his body, then removing other parts [[SoundOnlyDeath offscreen]].
** Shinobi Shaw is a rare example of a villain with such powers - his powers are identical to Kitty's and squeezing people's hearts while still in their chest is his signature move.
** ''ComicBook/NewMutants'':
*** The character Elixir has the ability to control the biological structures of organic matter. Normally this power manifests as HealingHands, but he is also capable of using them to deliberately infect people with diseases. He's used this power to outright kill one villain, and gave another an inoperable brain tumor - in the shape of an X. Using his powers in this way [[EvilCostumeSwitch turns his normally gold skin metallic black]]. In an alternate continuity story he teamed up with a mutant with TouchOfDeath, which when combined with his HealingHands caused parts of the victim to [[FateWorseThanDeath continually die and regenerate]]; a process said to be "quite painful".
*** In the ''Age of Apocalypse'' Marvel Continuity, fellow teleporter Blink demonstrates what happens if she closes one of her portals while somebody is halfway through. A fairly powerful (and ugly) villain gets literally turned to dust. When this version of Blink is brought back in ''Exiles'', she (temporarily) dispatches a ''[[FlyingBrick Superman]] {{Expy}}'' by teleporting a few tons of sand inside him.
** Also in the X-Universe, we have (or, thanks to M-Day, had) Jubilee, who could make pretty little fireworks in the air. She often used it to blind flying enemies, causing them to crash. However, there was a lot of foreshadowing indicating that she was actually an inversion - she functionally had ThePowerOfTheSun (indicated as a potential omega class) but a mental block kept her abilities at a relatively harmless level. This has actually been demonstrated on one occasion; when she thought Wolverine had been killed by the Mandarin, she absolutely lost her shit and let out a burst of energy so massive it ''leveled the Mandarin's castle''. The place was so thoroughly wrecked that the Mandarin was never able to use it again.
*** In one issue, she used her powers to run a fusion reactor by channeling her powers directly inside it.
*** Even with the mental block restraining her powers to a mostly-harmless level, when Jubilee caught her parents' murderers, she noted that by putting her fingers to their ears and using her powers she'd be able to fry their brains. Though very tempted, she refrained from doing so.
** ComicBook/{{Dazzler}}:
*** She originally had the power to convert sound into light. Then it turned out she could focus the lights into lasers. ''Then'' it was hinted that, given time, she could reach the point where she could convert ''any'' of the fundamental forms of energy into any other, effectively becoming a god.
*** In her old solo series, she once channeled the ocean's roar into a beam [[DidYouJustPunchOutCthulhu strong enough to stun Galactus]].
*** The Klaw is made of soundwaves. Naturally, it didn't end well for him when he fought Dazzler.
*** There's also the fact that the word "light" can be interpreted fairly loosely, and technically refers to any form of electromagnetic radiation... including gamma rays and micro waves.
** Iceman:
*** He usually slides around on ice slides, turns into ice, and throws ice spikes at people. When Emma Frost took over his mind, she was able to get him to turn his entire body into water, enter a river, and come out downstream perfectly fine. She also used moisture to make weapons more effectively, and turned Iceman into a gas as well as a liquid. The entire X-Men Gold team wasn't able to stop him. If he gets hurt as ice and turns back to normal, it heals. Bobby has been confirmed as an "Omega-level" mutant, which, while never defined, seems to basically amount to "demigod". If only he wasn't so lazy. One enduring effect of this revelation is that Bobby has become even more of a go-to candidate than Wolverine to [[GoodThingYouCanHeal not-quite-kill]] to show how dangerous a villain is, since he can be literally vaporized and still reassemble himself back into water, then ice, then flesh.
*** In the story in which he's a teacher at Wolverine's school, Logan asked him to start being serious. He soon delivers - in the form of ''multiple ice clones''.
** ''X-men'' ally Sage's power revolved around helping other mutants control their and strengthen their powers. ''X-men'' enemy Fabian Cortez had the same ability, but would push a mutant's power out of control, killing them. Cortez once did this to '''ComicBook/{{Magneto}}''', and almost succeeded in killing him. Unfortunately for all involved, [[CameBackStrong this made Magento even more powerful when he recovered]].
** One-time X-Man Dr. Cecilia Reyes initially had a personal forcefield that would protect her from harm (mostly). With a little practice, she discovered she could make the forcefield spikey...
** A ''self-inflicted'' example was Sally Floyd's mutant daughter, Minnie, who developed the power to [[MerlinSickness reverse her age]]. Since this manifested when she was only two years old, she had no way to control it, regressing until she turned back into a fetus and died.
* ''Franchise/SpiderMan'':
** Minor villain Mr. Brownstone has the ability to teleport matter...but only a few grams at a time. Since he works as a drug dealer, a few grams of heroin teleported straight to the heart is all he needs to incapacitate or kill someone. On a more mundane but equally criminal front, it can be used to immediately get a customer high by teleporting a smaller dose of heroin directly into their bloodstream.
** Many people think that the villain Shocker is a loser ButtMonkey and that his sonic gauntlets are useless. These people are unaware that said sonic gauntlets can kill or deafen people and cause buildings to collapse if he cranks them up high-enough. He's canonically used them to take out ''the Punisher'' in a single hit. The only reason Shocker isn't an a-list, city-wrecking bad guy is because he's also a ConsummateProfessional and prefers to keep his head low. Blowing up buildings doesn't pay, and while murder ''[[ProfessionalKiller can]]'' pay it also draws a lot more hero attention than mere theft.
* In the ''Troy'' universe, Cixi learns to use her ability - water temperature control - to cause all blood in a body to boil instantly, described in-universe as lethal even to teleporters. Although prequel issues have shown her to manipulate other body fluids shortly after her powers manifested.
* ''ComicBook/FantasticFour'' has Invisible Woman (a.k.a. Sue Storm):
** Quoted above, she ability to [[CaptainObvious turn invisible]] and [[BarrierWarrior create force-fields]]. Humble as these abilities appear, Sue is regarded as the most powerful member of the Fantastic Four. She has developed some brilliant applications of her force fields ranging from creating steps to walk on air to massive battering rams. She can, as she stated in the [[Film/FantasticFour movie]], create a force field inside a body and expand it with lethal - and messy - results.
** In the ''ComicBook/MarvelZombies'' comics, she demonstrated that you kill a zombie by destroying its brain by going MamaBear on a zombie She-Hulk.
** Her invisibility extends to those around her as well. And while not lethal, she was able to blind a pack of zombies by making their optic nerves invisible. [[ArsonMurderAndJaywalking She also once threatened a classroom full of teenagers that she could make their clothes invisible.]]
** Also she could make the skin, flesh and skull of a person's head become invisible, allowing ordinary sunlight to directly reach a person's vulnerable brain, rapidly causing heat stroke and slowly lobotimizing them.
** Invisibility could also, in theory, make a section of the Earth's Ozone Layer become invisible (as in it does not distort or deflect solar radiation), allowing the full might of the Sun to burn whatever she wanted.
** In Four, at one point she creates a forcefield surrounding herself and her family, protecting them from the villain. Then she creates another forcefield encompassing her and the villain. Then she starts extending the first forcefield, crushing said villain into the second one until he surrendered.
** The various lethal uses of her powers can be frequently be seen being used by the Super-Skrull (he has all the powers of the F4). He of course doesn't have Sue's good nature, so he doesn't hold back as much as she does. Also, in the Exiles comic (A book about a reality hopping super hero team), they once visited a reality where Sue was the leader of Hydra and showed how horrifying her powers can be.
** Sue (while evil) also once threatened to kill a man by creating a tiny force field in his carotid artery, which would cause a massive and probably fatal stroke.
** Sue Richards' force fields are hyperspace-sourced. Hyperspace is, in the Marvel Universe, the source of all energy. This allowed her to destroy a ''Celestial's'' physical form. The Celestials are a race of PhysicalGod EldritchAbomination Precursors. Their antibodies are strong enough to hurt Thor. Sue obliterated one of them effortlessly. She is the only mortal who has ever accomplished such a feat.
* In the ''ComicBook/RisingStars'' comic, a girl whose power is to psychically manipulate small objects is later shown to have grown to be a traceless government assassin: she simply pinches the victim's carotid artery from a short distance away.
* ''ComicBook/{{Watchmen}}''
** The Comedian at one point uses non-lethal rounds lethally -- tasers to the face, shooting someone in the chest with a tear-gas grenade from a few feet away.
** And of course, there's [[http://www.youtube.com/watch?v=qNfWlt69WKI Rorschach's famous usage of his grappling gun]].
* Ya know Comicbook/{{Aquaman}}'s power to control fish? Well, it's a stretch, but he can apparently ''shut down the part of your brain that's the same as a fish's'', causing you to become braindead. Writers love doing this with Aquaman (there is a reason he is the image for HeartIsAnAwesomePower).
* Franchise/{{Batman}}'s love interest Shondra Kinsolving had a low-level healing ability. [[spoiler:She once used it to kill her abusive father by healing him to ''death''; her brother, while manipulating her to do something similar to an entire village, explains that she makes people so fit that their hearts explode. He plans to turn Shondra into a WMD, that can kill people from anywhere in the world, and nearly succeeds.]]
* ''ComicBook/ElfQuest'':
** Redlance has the benign power to shape wood and make plants grow. A peaceful sort, he's badly traumatized after he's forced to [[spoiler: make thorns sprout from his spear's shaft to pierce the clutching hands of a troll]] in the heat of battle.
** The comic also has the "inverted healing powers" trick. Leetah is basically sickened by the idea and uses her power in that way only very, very rarely as a last resort, but Winnowill takes it and turns it up to eleven, especially post-timeskip when she's shown using her magic to casually turn normal animals into monsters and on at least one occasion kills several humans on the spot by turning her flesh-warping powers on ''them''. By the time the "Kings of the Broken Wheel" storyline rolls around it's kind of hard to remember that she even ''started out'' as "merely" the Gliders' SmugSnake designated healer.
* Mentioned in Frank Miller's ''ComicBook/TheDarkKnightStrikesAgain''. Batman launches a series of strikes to free superheroes who have been imprisoned by Lex Luthor's rogue government. During one of the missions, Batman's narration reads "he could kill us all; for him, it would be easy." The panels then reveal who he's talking about... and it's [[http://2.bp.blogspot.com/_hvBsDbuV_Ng/S8QdNeuqMpI/AAAAAAAAB18/0yKV9Pb36O8/s1600/DK2Plas.jpg Plastic Man]].
** One time, Plastic Man lost his cool after Rama Khan grievously injured Martian Manhunter. The result was Plastic Man turning into a giant snake and viciously crushing the guy like a boa constrictor. The attack was so brutal it ended up giving Khan brain damage and rendering him catatonic. [[BewareTheNiceOnes Don't fuck with Plastic Man]].
** Batman famously (or infamously given how often they fall into villainous hands) has contingency plans for how to take down every other hero in the event of them turning evil. When Martian Manhunter went insane and became the nearly unstoppable Fernus the Burning (as the name implies he no longer has the Martian vulnerability to fire, and is still as strong and fast as Superman while also having psychic powers), Batman's contingency plan is Plastic Man.
* ComicBook/SquirrelGirl's powers are simply defined as possessing various squirrel-like abilities, including the ability to communicate with other squirrels. Yet she manages to [[ParodySue canonically]] be the ''most powerful being'' in the Marvel universe.
* ''ComicBook/PS238'':
** The First School for Metaprodigies (super-kids), kids with powers 'unsuited for crime-fighting' go to the special 'Rainmaker' class, where they learn to use their powers in friendly, non-hostile ways that'll make them highly valuable to the private sector. The class includes a [[PhysicalGod mortal incarnation]] of Hestia, the Goddess of the Hearth (who can promote fertility and forge harmony within a troubled family). Another kid can turn anything edible, delicious, and nutritious. Other powers includes GreenThumb, superfast tunneling, and creating music. All harmless but no doubt profitable in the right places. Until the LowerDeckEpisode, 'The Rainmaker Cometh'... turns out Hestia becomes nigh-omnipotent if she's protecting a home from an interloper, that suddenly-growing trees are an effective way to swat flying foes from the skies, while properly amplified music can disorient and stun. And of course, the digger can take people with him underground... and leave them there.
** The terrifying potential of the food-creator goes unmentioned - this isn't a horror-comic, after all. It's clear, though, that his powers change the consistency of the object, since he's seen eating rocks despite having non-superpowered teeth. So imagine if he just went and transformed your body into something with the consistency of whipped cream...
** Incidentally, the titular Rainmaker that the class and the episode is named for, was one of these too. The first superpowered individual to appear with a 'harmless' power - to make it rain, or STOP raining. Useful for helping out farmers, but otherwise no biggie. So the GovernmentConspiracy spirits him away to a secret lab to use him as a guinea-pig in order to perform basic research on the hows and whys of superpowers, just 'cuz he can't fight back effectively. One MadScientist experiment later, and he creates a flood that effectively destroys the entire facility.
* ''ComicBook/GreatLakesAvengers'':
** Most of them have pretty useful powers, but the most dangerous/powerful member of the team is canonically ''Door Man'', a living portal whose powers have a fairly short range. He's capable of sending attacks right back at enemies and has also used his powers to help break into maximum security areas. In one infamous incident, his powers actually killed one of his own teammates ''by accident''; a villain tossed a sai at Door Man who instinctively activated his powers, unaware that Grasshopper was standing right behind him. The weapon proceeded to fly harmlessly through Door Man and impale Grasshopper through the skull, an event so traumatic it sent Door Man into a deep depression where he refused to use his powers and tried to drive Squirrel Girl off the team because he was terrified of accidentally hurting her.
** Door Man's powers have been revealed to work by tapping into [[HyperspaceIsAScaryPlace the Darkforce Dimension]], the same dimension that turn Marcus Daniels into the insane supervillain Blackout. That means that he essentially sends objects and people that pass through him to a nightmarish world of pure energy and yanks them back. This means that he could theoretically ''leave'' people there if he wanted to (though Door Man would never do so; he's far to much of a NiceGuy).
* You wouldn't think that superspeed and vibration would have many lethal effects unless you crashed into things. However as [[Franchise/TheFlash the Reverse-Flash]] has shown, that power can be horrifyingly deadly if used right. One famous issue had him kill Barry Allen's wife Iris by vibrating his hand to insane speeds that allowed him to [[NightmareFuel phase his fist into her skull]]. He's also regularly exploits a not-often mentioned potential side effect of going [[FasterThanLightTravel faster than light]]; ''time travel''. The only reason he hasn't just erased the Flash from history is because doing so would erase himself too thanks to a StableTimeLoop and GrandfatherParadox.
* ''ComicBook/NewGods'': Glorious Godfrey's power is to be handsome and be manipulative. He's actually ComicBook/{{Darkseid}}'s vanguard when conquering planets, using him and his army of "Justifiers" to rid planets of their superheroes through pure rhetoric and persuasion, as seen in the ''ComicBook/{{Legends}}'' event and the Reach invasion in ''WesternAnimation/YoungJustice''.
* Gates from ''ComicBook/LegionOfSuperHeroes'' has the power to [[ThinkingUpPortals create portals]] that he and his teammates could use to travel long distances. Said portals also have sharp edges that can [[PortalCut destroy anything they open inside of]], such as [[spoiler:Ra's al Ghul arm]].
* Amelia Mintz from ''ComicBook/{{Chew}}'' can write or talk about food so vividly that it can cause people to actually taste it. While it definitely makes her a good restaurant critic, it doesn't look that harmful... until [[BrownNote she sends several armed terrorists to the hospital by loudly reciting an unabridged review of a particularly bad restaurant.]] Later her powers were revealed to be able [[spoiler:to induce fatal food poisoning.]]
** Xocoscalpere has the power to sculpt chocolate with such incredible accuracy, that anything that he crafts can mimic properties of the real things. Naturally, this power is used almost exclusively for making weapons - like turning chocolate bars from a nearby vending machine into throwing knives, for example.
** There also cibopassimy - which allows the user to telepathically broadcast something to all people in the world. While this power doesn't seem scary, it can broadcast a BrownNote, which [[PersonofMassDestruction was exploited with a devastating effect.]]

[[folder:Fan Works]]
* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'': At first, it seems like all Italy can do is [[SuperSpeed run]]. However, since he can [[RequiredSecondaryPowers accelerate and decelerate]] [[NotTheFallThatKillsYou without dying or be even remotely harmed on impact]] because he is [[{{Immortality}} immortal]], if he decides to run into you with a sword in hand...thank goodness he is ''[[NiceGuy way]]'' [[NiceGuy too nice to even consider this]].
* ''Fanfic/ChildOfTheStorm'' has Sean Cassidy, a.k.a. Banshee, whose power is, at its most basic, a case of MakeMeWannaShout. Thanks to multiple decades of practise, he can use it for all sorts of delightful things, like liquefying granite and shattering wands to powder. And it also works on ''human bone''. And that's leaving aside his CompellingVoice, which he once used to on a RoaringRampageOfRevenge that gave Nick Fury ''nightmares'', and his ability to dampen sound around him, meaning that he can pull a StealthHiBye that would impress Batman and, in one case, make sure a claymore mine goes off completely silently.
* ''Fanfic/PokeWars'' has these aplenty because of the [[PowerLimiter dampener]] [[MassSuperEmpoweringEvent removal]]. Want an example? Gravity can [[YourHeadAsplode crush skulls]], and String Shot can be honed as thin as RazorWire.
* ''Apocalypse Johto'', a Webcomic/NuzlockeComics spin-off with a similar storyline to ''Fanfic/PokeWars'', has wild Abra using Teleport for a TeleFrag, among other things.
* An early chapter of ''Fanfic/HarryPotterAndTheMethodsOfRationality'' has Professor [=McGonagall=] explain to the class the many horrific ways Transfiguration can be used to harm (intentionally or not), since things eventually return to its normal form, and she forces the students to take an oath to avoid many very specific situations, such as never transforming things into a gas, fluid or ingestable. (Imagine turning a piece of steel into wine, serving it to someone, then waiting for it to turn back...) The fact that such a thing is never mentioned in the original books, and that preteen kids are instead blithely instructed to transform rats into goblets and other experimental cruelties is rather... unsettling.
* A now-disappeared InNameOnly ''Anime/YuGiOh'' fanfiction featured the Yami/Hikari pairs as ancient avatars of opposing forces, including Light and Darkness, Order and Chaos, and Creation and Destruction. Yami claims that Malik can't kill him because Malik embodies Creation and has no control over Destruction, but Marik assures him that isn't true.
--> '''Malik''': "I could ''create'' pieces of shrapnel inside your body right next to your vital organs. Or I could ''create'' a box around you and let you breathe yourself to death."
* In ''Fanfic/{{Game Theory|LyricalNanoha}}'', one of the original characters uses a medical spell meant for gathering oxygen to assist someone who is having difficulty breathing to start a fire with the concentrated gas.
** Also, Lotte uses a binding spell to ''strangle'' someone.
* [[WesternAnimation/TeenTitans Jinx]] in ''[[http://www.fanfiction.net/s/9051372/1/Consequence-of-Misunderstandings Consequence of Misunderstandings]]'' uses her bad luck powers this way. Used on an inanimate object, they cause it to break (handcuffs for example). Used on a person, they cause anything from a sprained ankle to a massive aneurysm. She defeats Starfire by sniping her with a hex bolt that gave her a heart attack.
** In [[https://www.fanfiction.net/s/6263444/1/Transition Transition]] the police accidentally put her in a CryoPrison rather than a her usual cell due to a power boost, turns out her powers now [[PowerIncontinence have something like an autopilot function]] [[TheUnfettered but no self restraint with her brain on ice]], so she starts pulling antics right out of FinalDestination and racks up a three digit bodycount in her sleep. Naturally, the cops leave her alone after that.
* One ''ComicBook/{{Hitman}}'' arc had a supervillainess whose only power was to make roses magically grow. She mostly used it to horribly kill people by making roses grow inside them.

[[folder:Films -- Live-Action]]
* ''Film/StarTrekVITheUndiscoveredCountry'' established that even a phaser on the stun setting can kill if used at point-blank range to the head.
* In ''Film/MysteryMen'', Dr. Heller (played by none other than Tom Waits) designs only non-lethal weapons. For some reason, a tornado in a can is non-lethal.
-->'''Dr. Heller:''' Totally non-lethal, totally effective.
* Azazel in ''Film/XMenFirstClass'' teleports hundreds of feet up with his foes, then teleports back down without them. Gravity does the rest.
** When Magneto finally confronts Sebastian Shaw, he uses his magnetic power to manipulate a single coin... [[spoiler:which he slowly drives into his skull and through his brain.]]
* In ''Film/{{Push}}'', those known as "Stitches" have the power to repair all physical injury simply by laying their hands on a person. However, it also works ''the other way around'', leading to the main character being incapacitated when an enemy Stitch touches him and dislocates various bones and organs.

* In the ''Literature/{{Temps}}'' story "Leaks" by Creator/DavidLangford, the protagonist has the almost-entirely-useless superpower of being able to teleport beer out of other people's glasses into his own. He falls into the hands of a mad scientist who plans to experiment on him to find out if it's possible to extend his power to other beverages in other types of container, and [[spoiler:things go very badly for the madguy once it occurs to the protagonist to wonder whether it will also work on ''bodies'' and ''blood'']].
* In Creator/TanyaHuff's ''The Quartered Sea'', a [[ElementalPowers bard]] ([[spoiler:Benedikt]]) kills someone by telling the kigh to [[spoiler:remove all of the water from her body]].
* Opal Cowan's glassblowing powers can be turned to much more lethal ends in ''Literature/IxiaAndSitia''.
* In the ''Literature/WildCards'' universe:
** The ace Water Lily can kill by instantly removing all water from a person's body as the lethal form of her water-gathering and minor water control.
** The ace Bagabond controls small city animals, but can kill via causing traffic accidents or ordering cats and dogs into massive kamikaze attacks.
* In ''Literature/{{Elvenblood}}'', male Elves are taught combat magic, but females are taught mostly aesthetic things, such as sculpting flowers into fantastic shapes. One of the females, Sheyrena an Treves, defects to the side of the half-blood Wizards -- it later turns out that she can use variants of the 'useless' female magics to make food from leaves in the wilderness, and even [[spoiler:stop a heart]].
* In ''Literature/TheBlackMagicianTrilogy'', both factions possess some magical techniques which the others do not. The enemy wizards know BlackMagic which boosts their power to insane levels. The good guys know... [[HealingHands Healing]]. [[spoiler: Turns out that since they didn't realise such magic was possible, the enemy wizards don't know to block it. This allows a protagonist to speed up an enemy wizard's heart until he has a heart attack.]]
* ''Literature/HarryPotter'':
** In ''Literature/HarryPotterAndTheDeathlyHallows'', Harry's SignatureMove ''Expelliarmus'' betrays him because, as Harry points out later, using a stunning spell on somebody who's on a broomstick hundreds of feet up in the air would be just as lethal as the "unforgivable" killing curse.
** Parodied in the ''[[http://www.sluggy.com/comics/archives/daily/080328 Giblets of Fiber]]'' storyline in ''Webcomic/SluggyFreelance'', where it is pointed out that it would be stupid to make the killing curse forbidden when what you really need to do is make all murder illegal, since it can be easily achieved with simple spells and a little creativity.
* Creator/LarryNiven's ''Literature/KnownSpace'':
** The 'verse has what's called the Kzinti Lesson: "[[WeaponizedExhaust The more efficient a reaction drive, the more effective a weapon it makes]]". It's called that because the supposedly-weaponless, pacifist humans used their light-sail drives (powered by giant lasers) and mass-driver mining tools (fires hyper-velocity ores around the asteroid belt, both burning off the impurities and getting the ore to market) to utterly trounce the hyper-militarized Kzinti empire. This theme is repeated in most of the ''Known Space'' stories; various harmless tools always seem to have a setting that makes things die horribly. Flashlights with adjustable focuses, starting diffuse as "light a room" and dialing all the way down to "laser beam". Communication lasers that have a setting for communicating with things in orbit, which just so happens to burn holes in anything not in orbit. Disintegrator mining tools, which work just as well on flesh as they do on rocks. Humans never seem to have dedicated weapons, just loads of useful tools that ALSO can kill things.
** Many of those belong to Nessus, a Pierson's Puppeteer. Louis specifically mentions that Nessus could point to every single piece of equipment the expedition has and say "That is not a weapon, we brought it for thus-and-so reason," but there are very few pieces of equipment that couldn't be ''used'' as a weapon, somehow. This, among other reasons, is why he christens their ship ''Lying Bastard''.
** The Kzin planet Warhead got new management ... and a new name ... when the Human planet Wunderland built, and transported into the system, a gigantic version of the digging tool. Actually, ''two'' versions; the normal digging tool operates by temporarily "suppressing the charge on the electron", but the Wunderland Treatymaker included another beam, that does the same thing for the ''proton''. The two beams hit Warhead's surface about ten miles apart, resulting in what's described as a "gigantic, solid bar of lightning" between the two points, and the production of the planet Canyon's most distinctive and eponymous feature.
** While we're on Niven, Gil Hamilton lost his arm in an accident, but developed psychokinetic powers to compensate. They're weak and limited: he can only "reach" about as far as he could reach with his old arm, and can only lift very small weights ... but if the picture's good enough, he can "reach" through a television screen, and you don't need much strength to squeeze someone's heart.
* The [[ScaryDogmaticAliens Geo]][[HumanAliens meters]] in Creator/SergeyLukyanenko's ''Literature/TheStarsAreColdToys'' have no weapons and [[LanguageEqualsThought no word in their language for "enemy."]] [[SubvertedTrope But if you happen to be a "non-friend," then you're in for a world of hurt.]] Their "harmless" laser probes can suddenly slice through your starship armor like butter, and plenty of other tools can be used offensively. A single Geometer scoutship destroyed dozens of heavily-armed ships, some of which are capable of {{Earth Shattering Kaboom}}s. They are, however, pretty adept at designing race-specific plagues, all in the name of Friendship.
* The Loonies demonstrate that rocks are as good as nukes [[ColonyDrop if you drop them from sufficient altitude]] in ''Literature/TheMoonIsAHarshMistress''.
* In ''Literature/{{Neverwhere}}'' Door and the rest of her family have the power to open, well, doors or portals between places. While useful, it's not immediately obvious as having offensive capabilities. However, the second time she uses her power, it's to open a "door" in a man's chest. [[spoiler:At the end she also opens a door to the furthest place she can imagine, which sucks in [[FallenAngel Islington]], [[ThoseTwoBadGuys Croup and Vandemar]].]]
* ''Literature/TheWheelOfTime'':
** Portals that let you step through space can [[PortalCut cut you in half]] if you accidentally walk into their edges. In earlier novels this is just an unfortunate side effect, but later on characters develop roving gateways that can be swept across battlefields for ludicrous gibs. This is of particular use against Darkspawn, who can't travel through gateways at all so that the whole portal (not just the edge) is deadly. This then leads to piles of inhuman corpses at the other end of the portal. Generals are also able to use them to station lines of cannons in safe positions and fire through the portals at the enemy or get a birds-eye view of the battle for easy up-to-the-minute intelligence.
** Healing powers can also be used to ''stop'' a beating heart and for torture.
** Green Men are biological constructs with the ability to encourage plants to grow. In the Age of Legends, they were used to manage croplands. In the present day, one kills [[spoiler:Balthamel, one of the Forsaken,]] by [[BewareTheNiceOnes tearing him apart from within]] with fungi.
* In ''Literature/{{The Redemption of Althalus}}'' the protagonists have access to a nice house that happens to belong to their TeamMom goddess. Being the home of a major divinity, it can have as many rooms as you need with no concern for spatial physics, and the doors conveniently open anywhere you like. When the war starts, they use it to house their entire army, and use the doors to deploy entire companies behind enemy defense lines. The villains have almost the exact same thing, but ''their'' god isn't nearly as cooperative or imaginative.
* ''Literature/TheDresdenFiles'':
** Harry Dresden has a great deal of impressive magical powers, but his skills at quick-and-dirty [[DishingOutDirt earth evocation]] are less than stellar. He can't do much more on the fly than some telekinetic control of metal, like, say, a small ring of keys. Of course, a small ring of keys is a lethal weapon when thrown with proper force, as [[spoiler: Lord Raith]] learns the hard way when his eyes get gouged out.
*** He also knows a spell that can temporarily remove all gravity in a twenty-foot area and concentrate it in one spot. He uses it in a parking lot, simultaneously crushing a vampire and setting off a whole bunch of car alarms as a distraction.
** Earlier in the series, Harry also turns an otherwise useless spell, designed to take control of brooms for easy cleaning, and uses them to drive off a horde of poison scorpion golems.
** [[spoiler:Molly Carpenter]] is [[MasterOfIllusion incredibly skilled at illusions]], which, while extremely useful, aren't really a great combat-oriented power (at least, compared to Harry's [[PlayingWithFire massive amounts of fire]]). That is, until she uses her "One Woman Rave" to disorient and blind enemies and gets them to attack thin air/each other by making it look like she's in a different place than she actually is, or to make a DirtyCop think the man bribing him is reaching for a gun.
* Jim Butcher's other series, ''Literature/CodexAlera'', has powers whose use can be best described as playing with Lego. Even the most combat-oriented elements have non-combat application (inverse) such as using metalcraft to gild, using firecraft to make iceboxes ("coldstones"), earthcraft to mine, and so forth. The "softer" elements, water and wood, are often overlooked, but Tavi figures out that you could use clever applications of water and wood to make cracks in stone and fill them with plants to expand the cracks, and so on, effectively weaponize ''wear and tear''. When it happens it allows a single person to take down walls viewed previously as basically unassailable.
* In Creator/PiersAnthony:
** In ''Literature/{{Cluster}}'' novel ''Viscous Circle'', the Bands stage a mock fight for training in which they inadvertently kill (or possibly drive to suicide) those on the other side of the mock fight by using the light that transmits their emotions between individuals to transmit powerful HATE messages to the Bands on the other side. Afterward, they go through a HeroicBSOD and suicide themselves. It's pretty sad, really.
** His ''Literature/{{Xanth}}'' series has a few examples, but the most overt is Hugo, who has the power to conjure fruit out of thin air. Sounds unimpressive, but the odd magical biology of Xanth means that one application of this is to conjure pineapples (slang for '''hand grenades''' in the real world, but more literal in Xanth) out of thin air.
* In the ''Franchise/StarWars'' novel ''Red Harvest'', a member of the Agricultural Corps (basically where Jedi not good enough to become Knights usually end up) has the ability to communicate with plants. This allows her to [[spoiler:kill zombies created by a virus derived from one of her plants by communicating with the plant and convincing it to grow inside the zombies' bodies]].
* In the ''Literature/{{Nightside}}'' series, John Taylor has the power to... find things. He regularly uses this to take the bullets out of guns. This is useful on its own, but he's also done the same trick with the fillings and crowns from his opponents' teeth and the breath in an enemy's lungs, and he has claimed to be able to do this with organs as well.
* ''Literature/TheBelgariad'':
** Relg has the ability to move through solid rock, which is extremely useful for pathfinding or rescue missions, but seems like a non-combat ability - until it turns out that he can also use it to push other people into the rock and leave them there.
** Garion and Durnik - being powerful wizards, have plenty of deadly powers at their command, but they often use their farmboy-simplicity to use powers in ways other people wouldn't think of. Tearing down a wall psychically? Impossible. Loosening the underground rivers beneath the wall, so the dirt can no longer support it? Half a day's work without breaking a sweat.
* Tamora Pierce's ''Literature/CircleOfMagic'' series:
** Many of the ambient mages' powers are like this. The most obvious would be the abilities of "stitch witches" like Lark and Sandry. They have control over thread. Awww, what a quaint little power. Now, just remember that your clothes are made of thread, and imagine what happens if you get them to ''squeeze''.
** Sandry's foster brother Briar can also control plants. This works in his favor if someone has an allergy to plants. In one scene, he ties up a girl in roses, which she's allergic to. In another, he attacks someone with thorns. He also once [[spoiler: tore apart an entire palace by growing plants from the inside out.]]
* Allomancers in the ''Literature/{{Mistborn}}'' books can have a variety of powers, and while some of them are very flashy (SuperStrength, telekinetic metal control), others are relatively nonlethal at first glance (the ability to calm emotions, SuperSenses). This does not stop the protagonist from using the former as a downright devastating EmotionBomb or someone whose only ability is the latter from abusing it until he can [[CombatClairvoyance predict others' actions]] from the feel of the air currents as they start to move.
* The ''TabletopGame/{{Warhammer 40000}}'' novel ''Literature/PathOfTheRenegade'' features and Exodite Eldar worldsinger, who has psychic abilities that allow her to commune with the World Spirit and effectively make her a FriendToAllLivingThings, allowing her to do things like read emotions, make plants grow and calm down raging beasts. As far as psychic powers in 40k go, that doesn't seem all that impressive. That is, until the end of the novel when she [[spoiler: kills a whole bunch of Dark Eldar by using her powers on a deadly virus]].
* In ''Literature/TheAdversaryCycle'' book ''The Touch'', the Dat-tay-vao, which is a healing power, can [[TouchOfDeath work in reverse]] if anyone gets in the way of the person who has it.
* ''Literature/KushielsLegacy'' has a group of rather inept and foolhardy sorcerers who summon a demon which can teach the language of [[SpeaksFluentAnimal animals.]] The demon, being a demon, agrees to teach them the language...of ants. This seems to be worse than useless...until [[spoiler: one of them uses it to command an army of vicious carnivorous tropical ants and attempts to make himself a GodEmperor with it]].
* Cricket, a minor villain in ''Literature/{{Relativity}},'' has the power to ''talk to insects (and spiders)'', which doesn't sound very threatening until he ''commands a swarm of bees to sting someone to death.''
* In the novel and film ''Literature/{{Ragtime}}'', a character is an expert at making fireworks. This is regarded as a pointlessly silly skill, until he clarifies that fireworks are just carefully-controlled [[LethalJokeItem bombs.]] Everyone stops laughing.
* In ''Literature/SuperPowereds'', [[SuperpoweredAlterEgo Roy]] is a typical arrogant MadeOfIron Super with SuperStrength. He's goaded into challenging the top-ranking male student for his spot. Figuring his typical AttackAttackAttack approach will work, he quickly finds out that there's a reason the other student is number one. The other guy has perfect control over his body and mind. When Roy hears this, he doesn't think much of this power, until the other student explains that it isn't much by itself, but it has allowed him to ingest massive quantities of minerals in order to toughen his muscles and bones to superhuman levels, as well as allowing him to easily read other students' body language and SuperReflexes.
* In ''Literature/StrangerAndStranger'', [[spoiler:Ainslee discovers this capacity of her healing Blessing.]]
* In'' Literature/InheritanceCycle'', is revealed that Murtagh's [[spoiler:and Eragon's]] mother was also Morzan's most trusted assassin. How did she gain this position? She was instructed to kill three men using one word from the LanguageOfMagic. The word in question was ''heal'': she accomplished it by using it to purge their negative emotions, effectively removing their will to do harm. She then killed them while they were unable to defend themselves.
* In ''Literature/ArtemisFowl: The Time Paradox'' Holly is able to use her [[HealingHands faerie healing powers]] to incapacitate a villain, by restoring his lost sense of smell. As this happens in the middle of a leather tannery full of chemicals, he's overwhelmed by all the bizarre and unpleasant smells that he never noticed before.
* ''Literature/{{Worm}}'' loves this trope. A lot. Anyone with a seemingly odd or over-specialized power can be relied upon to do something clever with it.
** Shatterbird is capable of controlling silicon with ultrasound. Silicon like in electronics or sand or glass--did we mention she can give it sudden explosive movement? Or that her range is large enough to ''encompass a city''? [[ParanoiaFuel Now think about how much glass you have near you right now]].
** Tattletale has the ability to fill in the blanks in incomplete information--essentially giving her superpowered intuition. In one early chapter[[note]][[http://parahumans.wordpress.com/2011/08/16/agitation-3-3/ Agitation 3.3]][[/note]], she uses this ability to deduce the complete floor plan of a bank from a satellite image of its footprint. In later chapters[[note]][[http://parahumans.wordpress.com/2013/02/26/scourge-19-3/ Scourge 19.3]] and [[http://parahumans.wordpress.com/2013/03/02/scourge-19-4/ 19.4]][[/note]], she figures out a way to [[spoiler:tear a hole in TheMultiverse and connect their universe to another]]. Much later on, this power is used to fill in the gaps that [[spoiler:the Entities deliberately left in the powers they gave humans to hide their presence]], letting her [[spoiler:extrapolate their true nature]] using those exact gaps.
** While generally not lethal, the sheer versatility and [[FridgeHorror potential terror]] of Panacea's power (as Taylor points out) makes one glad she usually sticks to healing, especially given how she [[spoiler:accidentally and irreversibly turned her "sister", Glory Girl, into [[BodyHorror a mass of various body parts]]]].
** Trickster can [[TeleportersAndTransporters swap his current position with anyone he can see]], and do this with others as well. He can, for example, jump off a building and proceed to swap his position with a target, causing them to fall in his place- he actually uses a variation of this (with a stuffed dummy instead of himself) to take down [[SerialKiller Cherish]].
** Canary is an example of an [[AccidentalMurder accidental use of this trope]]. Her power causes [[CompellingVoice anybody who hears her sing to become susceptible to commands]]. The problem is, it comes with a side-effect of making victims extremely LiteralMinded. For one example, telling someone under the control of Canary's power to stand still will make them stand absolutely rigid- they won't even breathe or blink. For a second, Canary's only in the Birdcage, and hence considered a criminal in the first place because [[spoiler: she told her BastardBoyfriend to go screw himself- and he actually tried to.]]
** The Number Man's superpower is literally being GoodWithNumbers. What exactly does that allow him to do? Well, [[LongList among other things]], he can effortlessly dodge just about any attack, survive ten-story falls without a scratch, WallCrawl, [[ShatterPointTap shatter an enemy's skull with a tap of his finger]], take down a warehouse the size of a city block with a couple grenades in the right places, and is among the world's most dangerous [[ColdSniper Cold Snipers]]. As for how he uses those powers? [[spoiler: He used to be a member of the Slaughterhouse Nine--under the name Harbinger -- as (presumably) a ''teenager'', before he helped ''kill their leader'' at the time and left. Now he works for Cauldron and is one of the top-rated Thinkers in the world]].
** Taylor Hebert, ''the main character'', has the ability to command insects within two blocks of her location. '''All''' the insects within two blocks of her location, ''simultaneously''. The weakness of any individual insect doesn't matter that much when she sends out swarms of thousands of them (and the number of insects in the typical two block radius from a given urban point is usually much larger) at a time, and that's before she starts getting clever and does things like having hornets airlift in black widow spiders to drop on people she doesn't like.
** Nice Guy's power is to become TheNondescript. He's also a SerialKiller and gets away with brutal acts right in front of people, who see him as a harmless bystander, if they see him at all.
** The villain String Theory is a Tinker whose creations only work once and have to be set on a timer. However, if she has enough resources to work with, her devices can do just about anything. She could strike targets across the world, was threatening to [[ColonyDrop knock the moon out of orbit]] when she was captured, could inflict serious damage on [[OmnicidalManiac the Endbringers]], and even [[spoiler: managed to send ''[[PhysicalGod Scion]]'' flying into space with her G-Drive.]]
* ''Literature/TheStormlightArchive'': Windrunners and Bondsmiths share access to the Surge of Adhesion, which simply lets them stick things together. Turns out that this can be quite useful in a fight, as the Surgebinder sprays power over a large area, all his opponents stick to it, and then he kills them while they're stuck. It helps that the Surgebinder is immune to their own Adhesion.
* In ''Literature/TheSalvationWar'':
** In the first part the most damage demons have managed to do to humanity was by opening a portal between a human city and an active volcano. In-universe, that's what really happened to Sodom and Gomorrah.
** Demons and Angels have the power to control human minds. The Archangel Uriel has the power to control them into dying, and en masse at that.

[[folder:Live-Action TV]]
* In ''Series/{{Smallville}}'', [[spoiler:Chloe's EmpathicHealing apparently drains ComicBook/{{Brainiac}} severely when he attacks her, to the point he staggers and pants and says WhatTheHellAreYou. She later uses her SuperIntelligence to overload a mind-reading guy's head, shutting his brain down.]]
* ''Series/StarTrekTheNextGeneration'':
** It took a holodeck-generated character to hit on the obvious use of the holodeck as a tool that can be used to fool someone into thinking they were someplace they weren't and interacting with people who weren't there. But once it was hit on, it was used in several ''Trek'' episodes.
** Also in ''TNG'', [[CreatorsPet Wesley Crusher]] devised using the ''Enterprise'' main deflector array as a weapon against the Borg. Up till then, it was just the glowing dish on the belly side of the ship. Subsequently, several ''Trek'' ships used the deflector in a similar manner. The deflector dish became a go-to solve-everything tool, in fact - pretty much ''anything'' can be done by rerouting some {{Technobabble}} through the main deflector. (Mind you, using it as a WaveMotionGun ''never'' does any good.) There's a reason "Bounce a graviton particle beam off the main deflector dish/That's the way we do things lad; we're making shit up as we wish" is part of the chorus for Voltaire's song dedicated to technobabble.
** Additionally, while it's never addressed in-universe, FridgeLogic would indicate that many of the problems the crew faced could've been solved by Scotty teleporting a warhead into the BigBad's / MonsterOfTheWeek's lap.
*** It's been tried on ''very'' rare occasion, though usually prevented by the fact that you can't beam stuff through the shields (the enemy's ''or'' your own! The need, or inability, to drop shields to beam someone up while being shot at has come up several times.)
* ''Series/BabylonFive'':
** Lyta uses telekinesis to lightly slap a PSI cop ([[YourMindMakesItReal or made him think he was slapped]]). When the villains start wondering whether she could stop all of them, she blusters and says that she might make a mistake and "accidentally" cause a brain hemorrhage instead.
** In the first season, Jason Ironheart states that Psi Corps experiments in boosting telekinetic power and refining control is intended to be used to assassinate people by pinching arteries shut, contrary to the more benign and defense-oriented uses he thought were the goal when joining the project.
* In ''Series/{{Misfits}}'' the villain of the week gained the power to control dairy based products (or [[{{Whatevermancy}} "lactokinesis"]] as he calls it). You'd be surprised at how many people he can kill or seriously injure with yogurt and cheese, and quite creatively to boot. He even managed to take down ''Nathan'' of all people, by realising that while Nathan's power of immortality prevents him from being permanently killed, his ability to [[ResurrectiveImmortality heal only kicks in when he dies]]. Thus, the solution was to simply manipulate the dairy to pool in Nathan's brain, turning him into a vegetable, but keeping him ''still alive''.
* ''Series/{{Heroes}}'':
** In a nutshell, this was [[spoiler:Emma]]'s story arc in Volume 5.
** D.L.'s power of selective [[IntangibleMan intangibility]] allows him to stick a hand in someone and mess around with their organs. He almost kills Niki this way and kills [[spoiler:Linderman]] by sticking his hand through his head.
* ''Series/{{Alphas}}'' has Dr. Kerns, who has the DisabilitySuperpower of echolocation. [[spoiler:He can also modulate the frequency of it to such a degree to cause extreme and subtle structural damage to a building, and if given time he can enhance it into MakeMeWannaShout.]]
* ''Series/DoctorWho'': The Doctor's Sonic Screwdriver does [[NewPowersAsThePlotDemands just about anything]] the Doctor needs it to, [[ExactlyWhatItSaysOnTheTin including turning screws, with sonics]]. It's also as powerful as needed, so it's really only the Doctor's "generally pacifist unless you get him ''[[BewareTheNiceOnes really mad]]''" tendencies that keep it from being used lethally. The Master's ''laser'' screwdriver on the other hand, is very lethal. Because of lasers, and evil.
** In the episode [[Recap/DoctorWho50thASTheDayOfTheDoctor Day of the Doctor]], three incarnations of the Doctor use their sonic screwdrivers in unison and the combined force is enough to destroy a Dalek.
** Timelords has the ability to regenrate - create the new body, after current one got mortally wounded. While they doing that, their bodies emit beams of energy, that can be pretty powerful. [[spoiler:River Song]] manages to weaponize that by prompting soldiers to shoot her shortly after her regeneration, forcing her body to use remains of the regenerative energy healing bullet wounds and emitting shock wave, powerful enough to knock soldiers out. [[spoiler:Doctor managed to weaponize regeneration himself, after his regenerative cycle got replenished, which made his body emit [[UptoEleven giant beam of energy, powerful enough to destroy a dalek battleship and a town-leveling shock wave, that killed rest of dalek army]].]]
* In ''Series/TheAlmightyJohnsons'', Mike is Ullr, God of Games. He doesn't lose games, not ever. This does not extend to fights--unless someone bets on the fight. Then it's a game again, and he wins. He managed to completely outmaneuver [[spoiler:Colin, also known as Loki the trickster god, by saying "I won't let you hurt my family," to which Loki replied with a sarcastic "I'll bet." Mike accepted the bet...which made it a game. And suddenly there was nothing Loki could do to hurt Mike's family]].
* Joey in ''Series/AgentsOfSHIELD'' has the power to melt and reform metal at will- potentially destructive, but generally pretty harmless once he manages to get a handle on his powers. Then he uses it to kill Lucio in self-defense by reforming a metal bar into a pointed spike and driving it into the poor guy's heart. For his part, Joey is horrified at what he's done.
* Series/Lucifer has Uriel's powers of pattern reading. All he does is sit and observe a pattern. Once that pattern is memorized and mastered, he's untouchable in direct combat. And he's a quick learner to boot. He also makes patterns that can occur from a series of DisasterDominoes.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** The 3rd edition features quite a few spells that summon or conjure something somewhere within the spell's range. Sadistic players could easily confound their DM by choosing "Inside that orc"[[note]] this actually required the players and the GM to ignore the line under general spellcasting rules that you had to conjure creatures and objects in empty spaces[[/note]]. The next edition amends most conjuring rituals to say the caster needs to be able to see the location they are targeting, which mostly solves this (since if you can already see inside the highwayman's lungs, any sadistic spellcasting is purely recreational).
** A particularly famous version involves the lowest-level druid spell Create Water. The spell's evident purpose is to provide clean water for the adventuring party or maybe quench a small fire. Even at the lowest caster-level the spell creates a gallon of water: more then enough to give even large enemies a lethal case of hydrocephalus.
** The rules also state you cannot summon a creature outside of its habitat. This is primarily to stop people from [[RocksFallEverybodyDies dropping whales on bandits]]. From 100 feet up.
** Shrink Item. Combined with "Fly", allows to drop something really heavy on the enemy.
** The "Locate City" spell immediately notifies the caster of the location of a city within 10 miles. Seems harmless enough. With the right combination of reasonably minor feats (and a cooperative GM), it can become a nuclear-esque blast that kills everything within 10 miles and then resurrects them as Wraiths.[[note]]This one actually takes some explaining to make sense. As stated, the spell Locate City targets a city and notifies you of its location. Then, there's a feat that allows you to tack exactly 1 ice damage on to any spell you cast. There's another feat that states that if you do any ice damage to anything, you tack another 2d6 or so on top of it. Finally, there's a final feat that states that if you kill anything using a spell, in 24 hours it rises as a wight. Since the spell targets the entire city, it deals 2d6+1 cold damage to everything in the "area of effect" (the city). That's enough to kill most low-level non-adventurers, thus causing them to come back as wights. It's since been errataed that before the "Tack 1 ice damage" feat can add an ice damage, the spell has to deal at least 1 damage to begin with, rendering this tactic unfortunately moot. It can also be done using the Explosive Spell feat, which pushes all enemies within the area of effect to the outside of it-dealing damage based on how far they go. Given a spell with an area of effect measured in the miles, the resulting blast will kill just about anything.[[/note]]
** The first level spell Hypnotize is intended to be essentially a Jedi hand wave, but the wording made it so that even after the spell wore off the subject was "one step more friendly" in the regards of whatever you hypnotized them to do. ''D&D'' quantifies friendliness, and explicitly states that the highest level, Fanatical, is enough to make people throw themselves in front of rampaging dragons for you. A first level character given enough time and castings can brainwash entire continents into being their die-hard lackeys.
** Under some interpretations of the rules, a Cleric with healing spells can be the most dangerous thing to undead, as healing magic causes them to take damage. This same rule is explicitly described as one of the few sure ways to kill a Nilbog, a (non-undead) creature that actually ''gains'' hit points every time it sustains damage. Healing, on the other hand, does it injury.
* ''TabletopGame/WarhammerFantasyRoleplay'' has the "Light" spell, which turns an inert object into a perpetual light source for as long as the caster is holding onto it. There's absolutely nothing to stop it being cast on a weapon, thus turning it into a make-shift magical item (necessary for killing certain enemies like Ghosts and Daemons). Thanks to bad wording, the first edition was an auto-kill spell. "The object glows brightly for one hour, and then vanishes."
* ''TabletopGame/PsionicsTheNextStageInHumanEvolution'':
** Technokinetics can make technology short out with EMP Blast. That’s annoying, but not so fatal, what with there being fail safes and dead switches and so on, right? Oh, if they have Penetration, it also works on cranial cybernetic implants…which explode when they short.
** Chaff Storm disrupts all communications for an area up to 40 miles around the user, which is useful for keeping enemies for calling in backup. Now, think about how much collateral damage that might cause in a residential area, since the user is also blocking calls to 911, hospitals, poison control,etc.
* ''TabletopGame/MagicTheGathering'': These kinds of things crop up all the time, generally by combining several annoying, but otherwise harmless spell effects into a monstrous instant win condition.
** "Mill deck" is a catch all term used to describe a deck that negates damage and forces the opponent to discard cards from their deck. This is their entire win strategy. Generally speaking both of these are viable tactics, but are used to hinder the opponent rather then outright destroy them. Combined, however, they quickly deplete your opponents deck to zero (which is an automatic loss) all the while countering, negating, and generally obliterating all sources of damage they attempt to put out. Only certain cards can even hinder this strategy in any form and most decks won't be running those since they are so situational. Made even more terrifying by the fact that being "milled" canonically equates to being {{Mind Rape}}d into an EmptyShell - what with lovely spells like [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=83597 Glimpse the Unthinkable]] and [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=370663 Traumatize]], and the EldritchAbomination [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=188962 Nemesis of Reason]].
** Many "instant win" decks revolve around drawing several specific cards and using them to essentially nuke your opponent before the match even begins. Needless to say the key cards tend to be pretty unassuming at a glance.
*** Using the "Vault nuke" as an example: The combo uses Protean Hulk (which summons creatures from your deck when it dies) and Flash (a cheap spell which summons creatures that instantly die if you don't pay a reduced cost). You Flash the Hulk, let it die, then use it's ability to summon up four Disciple of the Vault (which cause 1 damage every time an artifact creature leaves play) and eight 0/0 artifact creatures. The 0/0s die immediately due to having 0 toughness which causes each of the Disciples to deal 8 damage to the enemy for 32 damage (starting hp is 20) killing the opponent instantly. With the right back up cards this can be done on "turn 0" (essentially the setup phase before the fight begins) ensuring your enemy can't even respond to it.

[[folder:Video Games]]
* The classic ''VideoGame/{{Asteroids}}'' clone ''Maelstrom'' gives you 3 seconds of free shields at the beginning of every wave. Crafty players can use this time to swing their ships into asteroids for a quicker win.
* Pretty much all shield-type weapons in ''VideoGame/MegaMan'' work this way, wherein contact with the shield damages enemies just as if you shot them, but it's usually an inefficient way to go about it. However, the Water Shield can deliver up to 8 hits this way.
* Elizabeth in ''VideoGame/BioShockInfinite'' has the ability to open up tears in reality to alternate universes, essentially making windows to other worlds. The first time you see her use it, she opens up a Tear to Paris, to check how accurate her painting of the Eiffel Tower is. Later in the game she uses it to bring in gun or rocket turrets. Maximum deadliness occurs when she opens up a window to [[spoiler:a tornado. In the finale she teleports herself, Booker and Songbird, the giant robot-monster-bird-thing that was threatening them, to [[VideoGame/BioShock the underwater city of Rapture]]. She and Booker appear inside the city, but Songbird is outside. Crunch.]]
* ''VideoGame/{{Touhou}}'':
** Reimu Hakurei possesses the ability to fly, which is incredibly lame when considering nearly ''everyone else'' in the series can fly on top of whatever power they already possess. Except that Reimu can also, at a whim, ''fly away from reality'', making herself completely invulnerable, and if she didn't place a time limit on it (fighting in Gensoukyou being largely a game) she would never lose.
** Kogasa Tatara has the power to surprise people, which is unbelievably lame. Except that she managed to [[spoiler:surprise ''the player'' by reappearing as the Extra Stage midboss, complete with the required massive power boost]]. While she hasn't done anything else with it yet, fans have logically deduced that, as long as it is surprising enough, she could do almost anything she wants. It can be safely said that [[spoiler:few people expected her to appear again in stage 3 of Ten Desires]].
** Subverted by Yuuka Kazami, who has the power to [[WhatKindOfLamePowerIsHeartAnyway manipulate flowers]], which is as weak as it sounds. She can't make flowers bloom in an opponent's throat to stop their breathing or make them grow to giant size and attack people like [[Characters/BatmanRoguesGallery Poison Ivy]], or anything like that, she can just make them grow faster and healthier (as far as we know). She's still an outrageously powerful character despite this. She's simply got strong magic unrelated to her flower-manipulation, and is generally assumed to be physically powerful as well. It's the prime reason fans don't doubt her claims of being one of the strongest Youkai in existence.
* Several characters in ''VideoGame/GuardianHeroes'' have a shield that causes mild harm if touched. The Sky God, however, being enormous, has a ''huge'' shield that can kill loads of characters at once by smashing them against the arena boundary, which bounces them back into the shield, etc.
* ''VideoGame/TeamFortress2''
** The Medic's signature weapon, the Medigun, seems harmless enough; it heals teammates and, after a while, it builds up an "Ubercharge" that turns the healing target invulnerable for eight seconds. It's not so harmless when the Medic pops the charge on, say, a [[MightyGlacier Hea]][[MoreDakka vy]], who can and most likely ''will'' mow down more enemies than he could without said invulnerability.
*** According to the ''Meet the Medic'' video, the heavy's heart had to be replaced with a "mega baboon" heart after his own heart ''exploded'' from the force of an ubercharge. If nobody had such enhancements, it is very likely that the medigun could be abused to induce heart attacks, or worse, in the people the medic is "healing".
--> '''Medic:''' Now, most hearts couldn't withstand such voltage, but I'm fairly certain your heart-'''[[ExplosiveOverclocking *SPLORTCH*]]'''
--> '''Heavy''': (lying awake on a hospital bed, his heart removed from his body and freshly exploded) What was noise?
--> '''Medic''': (pulling off the remnants of the Heavy's heart off of the ubercharge gadget) The sound of progress, my friend.
** Pyro's airblast is fairly simple--for the price of some of your primary ammo, you fire a blast of compressed air. It does no damage whatsoever and has a fairly short effective range and a long recovery time before you can use it again. What good is it, then? Well, its main power can be described as 'pushing things.' Like, say, pushing [[TennisBoss an enemy rocket back at them]]. Or pushing enemies away from important targets, off cliffs, and into oncoming trains. Or 'pushing' a fire off a teammate to save their life. The airblast is arguably the ability with the greatest variety of uses in the game.
* In ''VideoGame/{{Disgaea 2|CursedMemories}}'', one of the Dark World maps has a bunch of mages standing on panels with a "reverse damage" effect - any damage-dealing effects they take heals them instead. But the inverse is also true - healing hurts them, and it isn't stopped by the Resistance stat, so even weak heal spells can kill them outright. Since healers are usually held back by their restrictions (they only get a pittance exp from healing, and no mana), this becomes a very potent grinding spot for them.
* ''{{VideoGame/KingsQuest}}'' series. Alexander of Daventry has some minor magical talent, mostly in UtilityMagic. The nastiest spells he knows call up a rainstorm. He's still more than capable of destroying evil sorcerers, breaking into castles, thwarting pirates, and ''challenging Death'' with that knowledge.
* At the beginning of ''VideoGame/{{Marathon}}'', the AI Durandal is mostly in charge of menial tasks on-board the ''Marathon'', among which are opening and closing doors. This is because Durandal was [[AIIsACrapshoot Rampant]], which in-universe causes an AI to grow exponentially in size and intelligence. However, his handler was attempting to use the sheer boredom and meaninglessness of these tasks to delay the progress of rampancy. It was thought that Durandal would then be unable to cause serious damage with the systems he controls. The handler apparently overlooked that "control over opening and closing doors" includes ''[[ThrownOutTheAirlock airlocks]]''...
* In ''VideoGame/BahamutLagoon'', a party with a positive healing level can use life-draining attacks.
* ''VideoGame/{{Elements}}'' has two such spells:
** "Gravity Pull" can redirect all attacks directed towards the player into one of their creatures. Usually this spell is used for defence, but using it on a Voodoo Doll (which shares all damage it sustains, including status effects, with the enemy player) would practically force your opponent to hit themselves.
** "Rage Potion" increases a target creature's attack by five points, but lowers its health by the same amount. This is a useful tool in eliminating creatures with low health, but it can also be used on a Voodoo Doll, simultaneously hurting the enemy and boosting the Doll's attack power.
* ''VideoGame/PokemonSunAndMoon'' has the Z-Move "Z-Splash". Like Splash, Z-Splash does nothing. Nothing but boost the {{Mon}}'s Attack stat by ''3'' stages, more than Swords Dance (boosts Attack by 2 stages).
* In ''VideoGame/GoldenSun'', Isaac's "Move" power is simply a floating hand that gently pushes large objects a short distance. In ''VideoGame/SuperSmashBrosBrawl'', the Assist Trophy version of Isaac uses Move to gently push your opponents a short distance... [[GravityIsAHarshMistress off the stage]].

[[folder:Visual Novels]]
* ''VisualNovel/UminekoWhenTheyCry'':
** Ronove has this kind of power. One of the 72 Great Demons and the butler of the Witch, Beatrice, he has no offensive magic unlike the Witches, Siesta Sisters or Purgatory Stakes. Ronove only has the ability to create impenetrable shields around himself. In Episode 4, he uses this to try to crush his opponent against a wall.
** Even more impressively, [[spoiler:Shannon]] used this and LoopholeAbuse to kill [[spoiler:MARIA, the Witch of Origins who could not be targeted by offensive abilities due to her Diplomatic Immunity]]. She did this by slowly expanding her shield until it crushed her, and her familiar [[spoiler:Sakutaro]] against a barrier [[spoiler:MARIA]] had made.
** Gaap, another of the 72 Great Demons has the Power to instantly move anything, anywhere using bottomless holes which can appear absolutely anywhere, but only when humans who do not believe in magic are not looking. Normally used to travel, move corpses and cause general mischief, she used this power in episode 4 of the visual novel to [[spoiler:redirect George's deadly Kick Fatality against Gaap and Jessica's unstoppable fist attack against Ronove towards each other. Thus causing the cousins George and Jessica to accidentally kill each other]]. This was despite the fact that [[spoiler:George]] and [[spoiler:Jessica]] were in completely different areas of the Ushiromiya Mansion at that time.
* Ryouma Hoshi from ''VisualNovel/NewDanganronpaV3'' is the Ultimate Tennis Player. Doesn't sound very intimidating, right? Well, this guy was responsible for killing off an entire mafia organization ''single-handedly'' using his custom-made steel tennis balls. This earned him the nickname "killer tennis" and got him sent to death row.

[[folder:Web Animation]]
* ''Machinima/RedVsBlue'', being based off of the ''Franchise/{{Halo}}'' setting, includes [[BeehiveBarrier Bubble Shields]]. It's well known that it reflects bullets from either side of the shield. What isn't usually thought of is that if you huck the generator like a football, you can trap and Swiss-cheese a sniper nest.

[[folder:Web Comics]]
* One ''Webcomic/SaturdayMorningBreakfastCereal'' [[http://www.smbc-comics.com/index.php?db=comics&id=499#comic comic]] features a girl who can make PreciousPuppies appear anywhere. (Hint: "anywhere" includes ''[[ChestBurster inside someone's body]]''.) Currently provides the trope's page image.
* The ''TabletopGame/MagicTheGathering'' webcomics:
** One scene depicts three of the planeswalkers in battle with a horde of ''nim'' (aka zombies). Elspeth's ability to fight is fairly obvious, as she is a highly-trained knight and quite adept with a blade. Koth, a geomancer, is also quite nasty in a fight, due both to being built like a rock (literally) and being able to conjure/hurl boulders at his foes at a whim. Then we have Venser, effectively the geek of the trio. No weapons, no real fighting skills, and his only ability seems to be teleporting, which doesn't seem useful against zombies...then he takes hold of two of them, teleports ''with'' them a few hundred feet in the air, then immediately 'ports back down ''without'' them. [[GravityIsAHarshMistress Gravity]] [[HilarityEnsues ensues]].
** Far earlier, in one of the Mirrodin Block novels, the protagonist is given a series of one-use magical artifacts, one of which will teleport her to any place she chooses to name. In a pinch, she realizes that "[[TeleFrag inside of a person]]" is a place...
* In ''Webcomic/{{Homestuck}}'', your powers are determined by your Title, which follows the format X of Y (as in [[MemeticMutation Gent of Piss]]). While the Aspect can be any monosyllabic concept like Mind, Hope, or Heart (most of which sound non-lethal), the actual Class can modify a non-lethal Aspect into a dangerous force.
** For example, a Prince of Mind would, based on game mechanics, be able to [[MindRape destroy the brains of his enemies]], and a Knight of Heart would be able to [[ImprobableWeaponUser weaponize souls]]. [[InvertedTrope Inversely]], a potentially-deadly Aspect, such as [[UnstoppableRage Rage]] or [[PowerOfTheVoid Void]], could be turned passive by its class. For example, an Heir of Void would just be able to make things [[FailedASpotCheck near-impossible to find]]. Of course, "things" [[HeartIsAnAwesomePower could include part of enemies or entire hostile armies]].
** For specific examples, we have John, the Heir of Breath. Doesn't sound that impressive compared to Time or Space manipulation. How about creating cyclones over lava, turning them into ''fire tornadoes'' with which to strike your enemy? Generating a windstorm so intense it ''drills through continents''? Global hurricanes within seconds? Turning into wind to make yourself untouchable? It's quite a useful and versatile power, really.
** There's also Dirk, the Prince of Heart. In Sburb's mechanics, Heart = Soul. Dirk is therefore able to ''tear a person's soul from their body''. Yikes. Going by this logic, the often by fandom portrayed as innocent and cute, Nepeta as the Rogue of Heart is able to ''yank a soul out of a body and then redistributing it under her allies''.
** And then there are the troll blood traits. Some are awesome: immense telekinetic powers, MindControl, and the like. Then there's Tavros, who can [[FriendToAllLivingThings control animals]]. The lethal part is that it affects enemy {{Mooks}} generated by Sburb/Sgrub, like imps and ogres, enabling Tavros to make them ''his'' minions and breeze through the game without ever touching his class powers. [[spoiler:Then he casually mentions to Jade that he can command [[RealityWarper First Guardians]] this way. Yes, ''talking to animals'' is a StoryBreakerPower in ''Homestuck'']].
** Light is similar. Light symbolizes fate, knowledge, and literal light. Sounds pretty weak, right? It has so far been used to navigate the lack of physical space between universes, kill enemies without its user lifting a finger by robbing them of their fortune, and [[MindRape Mind Raping]] someone into insanity. And ''all'' Light heroes have access to these powers, just to different extents.
** Jack Noir, after [[spoiler:obtaining power of a First Guardian]] not only get a ton of different deadly powers, but manage to weaponize non-lethal one - he used ability to turn his own body into a portal, to [[spoiler:redirect bullets, aimed at him, in Dave's back]].
** Jade has teleporting powers, similar to Jack's. She once threatened to kill Roxy by teleporting her intestines out of her body.
* ''Webcomic/DominicDeegan'': People constantly underestimate illusions. For some reason, MindControl magic is also scoffed at. To be fair, they usually fail to see through ''Luna'''s illusions, which are usually mimicking evocation magic... which she has a long history of actually being able to pull off, being the archmage successor to Miranda Deegan. It's not likely that people that weren't actually known for casting epic spells of destruction would be as convincing in their illusions.
* Collin from ''Webcomic/WhiteDarkLife'' is incredibly stupid up until he learns his latent abilities. Which is to walk on non-solid things and pass through solid things. Kind of like [[Manga/DGrayMan Tyki Mikk]] described above. What does he do with this? Dodge literally everything and tear "Snake-Jaw" out of the person he was possessing. A task that was impossible for several exorcists, an angel, and an almighty demon who can control almost anything.
* ''Webcomic/SluggyFreelance'', "Holiday Wars": You'd think when [[ItMakesSenseInContext Santa Claus has been transformed into an alien killing machine and is facing an army of Halloween and other holidays]], what would make him most dangerous would be his ''new'' abilities, not the old ones. But [[spoiler:what use is an army against a being that can [[SuperSpeed move so fast]] that he can deliver presents to the entire world in a single night? Since his chief opponent is the Easter Bunny (no, really, ItMakesSenseInContext), he also goes into egg-delivery mode, and they nuke it out [[TimeStandsStill while everyone else is frozen]].]]
* ''Webomic/{{Erfworld}}'': Some Caster disciplines have obvious combat applications. Others don't, and are generally intended for utility purposes, but can still be quite dangerous in the right circumstances.
** Sizemore's magical specialty is [[DishingOutDirt Dirtamancy]], which his Lord Stanley primarily utilizes for [[MundaneUtility digging tunnels]] and crafting {{Golems}} out of natural materials. But those same tunnels? Sizemore can collapse them on enemy units with a thought, or bend them into a maze to get attackers lost, or turn an entire tunnel system into a devious assortment of natural pitfalls and other traps. His magic also gives him an intuitive grasp of architecture and structure, allowing him to singlehandedly outflank an entire invading army. And when mentally linked with [[{{Necromancer}} Wanda]] during Chapter 1's climax? [[spoiler: He uncroaks (read: brings back to life) ''a volcano'', creating an enormous rain of lava that [[TotalPartyKill utterly incinerates both sides of the battle]] and permanently changes the surrounding landscape.]] Sizemore, as an ActualPacifist, is ''horrified'' by how terrifyingly lethal his magic can be when used properly.
** Dittomancers can, well, [[ExactlyWhatItSaysOnTheTin multiply things]]. Obviously useful for purposes like doubling army rations or increasing a nation's wealth, Jetstone's Dittomancer also demonstrates just how dangerous Dittomancy can be by multiplying an archer platoon's volley into a RainOfArrows that would make the Persians of ''Film/ThreeHundred'' proud.
** Hippiemancy is the setting's equivalent of WhiteMagic, with spells revolving around promoting peace, calming raging emotions, and [[GreenThumb growing plants]]. But in the hands of [[BitchInSheepsClothing Olive Branch]], each and every aspect of Hippiemancy gets turned on its head for use in war. Olive uses magic intended to promote peace and parley to restrain enemy factions her own forces can't overwhelm, then assassinates their leaders afterwards, or simply uses her CharmPerson magic to MindRape the enemy into hapless, pliable slaves. She even weaponizes her ability to grow plants to create lethal poisons for use in the aforementioned assassinations, and [[spoiler: renders the leader of her own side into a helpless PuppetQueen by forcefully addicting her to drug-addled plants grown by Olive herself.]] Olive's willingness and ability to turn magic intended for peace into a lethal weapon makes her a OneManArmy simply because her tactics are so out-of-the-box for a world whose military forces otherwise rely purely on brute force, and it's only because she grabs hold of the VillainBall and refuses to let go that she's ultimately defeated.

[[folder:Web Original]]
* ''Literature/WhateleyUniverse'': One of the primary goals of the school is to teach students to use their powers effectively, no matter how powerful or how limited. Even a few Underdogs eventually learn that powers that seem worthless can still be used to devastating effect with enough cunning and ruthlessness.
** Generator (Jade Sinclair) starts out with the power to cast a copy of her mind into an object and animate it for a little while. This is considered extremely lame by the standards of SuperheroSchool Whateley Academy with its powerful mages and {{Flying Brick}}s. Then she nails a werewolf to a tree. ''With railroad spikes.''
*** She's actually got one of the most terrifying powers, period. She could animate some wire- hey presto, instant flying strangling cords. By herself, she'd be a brilliant information broker... or assassin... or just about anything. Early on one of her teammates imagines what would happen if Jade projected herself into a pile of sand or a pool of water, before quickly resolving to never mention this to Jade and hope she didn't think of it herself. A later story includes her projecting herself into her own body to hold things in place and keep things functioning after being stabbed through the heart, doing the same to animate a handful of mook corpses, and then slaughtering her way through a secure facility as a "vampire princess" with a zombie army.
** Phase is an IntangibleMan. If he goes back to solid when within an object, he disintegrates its mass. He can vary his levels of mass, causing devastating effects. The only other known character with the same variation of density warping is Tinsnip, a virtually unstoppable professional assassin.
** While no one would argue that super-martial-arts is a wimpy power, Chaka doesn't really have anything else except some slightly improved Exemplar strength and intelligence. That intelligence has proved the critical factor, as she has [[NewPowersAsThePlotDemands found uses for her Ki powers]] that no one would have thought possible, letting her fight one-to-one against far more dangerous opponents.
** Gateway can create portals, and summon creatures through them. It's also been suggested that she could use them to TeleFrag opponents.
** The Siren powerset - being able to control your voice - sounds quite limited, until you see someone like Vox use it to make an EliteMook shoot his commanding officer, or Screech use it to [[MakeMeWannaShout completely liquefy a combat cyborg]].
** Aquerna was considered a joke - and ridiculed as a ComicBooks/SquirrelGirl wannabee - until she took a page out of that Marvel character's playbook and proved that a swarm of squirrels can indeed by quite effective. She also managed to outwit the Good Ol' Boys, something which they have yet to live down.
* Cale from ''Roleplay/DarwinsSoldiers'' can use his electrical powers to fuse dust particles in the air into glass. This does not sound impressive when compared to his other power ([[ShockAndAwe electrokinesis]]). However, this means that he is never unarmed. And he once shredded some terrorists with a [[FlechetteStorm swarm]] of glass daggers .
* Coatl in ''Literature/TrintonChronicles'' has a rather lethal and yet seemingly harmless set of powers; she can boost powers (and thus cause them to go haywire for SuperPowerMeltdown for villains) or her HealingHands can be pushed to the extent of causing cancer!
* In ''Literature/{{Anachronauts}}'', the human witch Emily enters a magical duel with the Fey Archmage Lilith, in which Lilith's condition, according to the rules, is that each participant can only use one spell. Emily doesn't know any combat spells, and specializes in spells with [[MundaneUtility useful effects such as making a perfect cup of tea.]] [[spoiler:Emily's condition is Heart's Guardian; anyone who cherishes the duelists can stand by them in the fight, which means her friends can join in. Emily dodges the blast of fire Lilith throws at her and uses her friends to gain an advantage, then materializes warm, steaming tea directly into Lilith's lungs. Emily then humiliates her opponent further by saving her life using CPR to get the fluid out of her lungs, putting Lilith in debt to Emily.]]\\\
Emily's ''real'' power is that she literally doesn't think like other witches; since magic destroys whatever it is written on when cast, and most human mages memorize spells, they just end up going nuts. Also, they're usually taught the standard brute-force spells, since the Fairie Summer Court thinks of them as disposable[[note]]In ''Franchise/StarWars'' terms, they're effectively the Sith.[[/note]]. Emily is/was CursedWithAwesome to be unable to memorize spells, and has to copy them and read them to cast them, retaining her sanity, and prefers utility spells, which means she has to think tactically in a way that tends to elude the other human witches (sanity loss) as well as the elves who trained them (not very creative). [[spoiler:Lilith, an elf, was one of the most powerful mages in the world, and her spell was basically just [[TabletopGame/DungeonsAndDragons Maximized Fireball]]]].
* ''Literature/EnterTheFarside'': Tether has the power to link two objects and bring them together. He uses this to throw things and return them back to him by linking that object to his gloves, and also throw people about by their clothes, amongst other things. Katrina can generate a white, vapour-like substance that she can superheat to cause serious scalds and burns.
* In ''[[Roleplay/InsaneCafeSeries Insane Cafe 3]]'', Nani exploits pepper spray's flammability to set fire to a group of mages.

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'':
** It's repeatedly mentioned that the titular art is primarily defensive in nature, wielded by the pacifistic Air Nomads, but a few times, like during the discovery of Monk Gyatso's body, we see that it ''can'' be used to devastating effect. This leads to a lot of AscendedFridgeHorror in ''WesternAnimation/TheLegendOfKorra'' when a dangerous criminal named Zaheer gains airbending after [[MassSuperEmpoweringEvent Harmonic Convergence]] and shows ''no'' qualms about using it on others [[spoiler:such as using it to asphyxiate the Earth Queen]].
** Water bending can also be applied in a rather nasty fashion known as ''blood bending'', essentially mind-controlling someone through the liquids in their body. It can also be assumed that it could be potentially used to freeze the liquids in a living person.
* ''WesternAnimation/CaptainPlanetAndThePlaneteers'': Not quite lethal, but far more harmful than it appeared -- Ma-Ti uses the power of heart to communicate with animals telepathically. [[WhatKindOfLamePowerIsHeartAnyway A pretty lame power]], until you realize that, had he wanted to, he could have easily brainwashed the entire population of Earth. In one episode, he uses it to save the Earth from a GreyGoo scenario by summoning a massive flock of birds to destroy a swarm of genetically-modified locusts before it can reach the mainland, something the rest of the group couldn't do with their elemental powers.
* Another example of water powers that aren't harmless but could have been infinitely worse: ''WesternAnimation/DarkwingDuck'' has a character called The Liquidator, who has apparently complete control of water. He can generate it, boil it, and turn it into "hard water" -- a yellow glue-like substance. Luckily for everyone involved, ''Darkwing Duck'' is a children's series, so we never get to see what might have happened if Liquidator had decided to turn the water of a living being's body into hard water... or boil it...
* ''WesternAnimation/JusticeLeague'':
** The ComicBook/MartianManhunter: He's dangerous enough already, but he uses his intangibility offensively at least once -- during his rampage through the Task-Force X, he reaches inside Deadshot's chest and does ''something'' to his heart that severely messes him up. And he takes out a mechanical baddie by similarly reaching into its head and ''pulling out'' what's inside.
** ComicBook/TheFlash:
*** Given that he has super-speed, his secondary ability goes mostly unnoticed: he can vibrate at a superhuman speed. Said vibrations create an unstable resonance which can [[StuffBlowingUp cause things to explode]].
*** To say nothing of running several times around the planet in a few seconds to gain enough momentum to punch Braniac out of Lex Luthor.
** An episode also features [[{{Expy}} expies]] of the ComicBook/WonderTwins from ''WesternAnimation/{{Superfriends}}'' with their same powers. Whereas the Wonder Twins were near-useless and rather incompetent, this episode shows how their powers (turning into various forms of water and turning into animals) could be used to easily infiltrate an office building and hold its leader hostage.
* In ''WesternAnimation/MiraculousLadybug'', several of the akuma villains Ladybug and Cat Noir face have abilities that fall under this, and often prove just as challenging as the villains with powers like WeatherManipulation, etc.
** Mr. Pidgeon can control pigeons. Even without taking into account him making them strong and tough enough to dent a metal door ''severely'', this allows him to cause chaos all over Paris, as it has ''millions'' of the feathered fiends.
** The Bubbler uses his bubbles to enact a mass kidnapping of all the adults in Paris.
** Lady Wi-Fi can "pause" people and teleport between phones, and very nearly reveals Ladybug's identity.
* Levitating objects with magic is the stock ability of every unicorn from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', and thus is a mundane part of every day life. Of course, this includes other ponies, since Rarity levitates her little sister around and Twilight Sparkle levitates her friends on a few occasions. Then "Magic Duel" airs and [[BrainwashedAndCrazy Trixie]] displays just how terrifying this ability can be if misused, since there [[FridgeHorror really doesn't seem to be anything a pony can do about it if levitated against their will]].
* Titular character from ''WesternAnimation/StevenUniverse'', as he himself admitted, has mostly defensive powers, like ability to generate a forcefield or [[HealingHands healing with his spit]], and has a shield as his personal weapon. However, he can make his forcefield grow spikes and throw his shield with enough force to slice a stone pillar in half.
* In ''WesternAnimation/WolverineAndTheXMen'', Nightcrawler, whose only mutant power is teleportation, puts it to devastating use against Spiral, by using it to PortalCut her robotic arms. Then he implicitly reminds her that he could easily do the same to her ''organic'' ones.
* ''WesternAnimation/XMenEvolution'': Shadowcat's ethereal form wreaks havoc on electronics. She's not afraid to weaponize it. Teaming up with Nightcrawler, this let her take out an attack chopper that is harassing them.
-->'''Nightcrawler:''' Hi! I'm Nightcrawler. This is Shadowcat.\\
'''Shadowcat:''' And ''this'' is your guidance computer.

* Honeybees have the ability to vibrate their flight muscles and raise their body temperature, which they usually use to keep themselves warm during the winter. Japanese honeybees have figured out how to weaponize this against Japanese hornets (who have exoskeletons the bees' stingers can't pierce, but also can't survive as high a temperature as a bee can) by attaching themselves to the hornet ''en masse'' and heating themselves up, frying the hornet from the outside in.
* The special ability of humans is "be creative". The seems unimpressive until you realize that 1) an unarmed human doesn't ''stay'' that way for long, and 2) the mastery of out-of-the-box tactic thinking means that other animals who fail to win early are almost certainly doomed to run out of countermeasures before the human runs out of ideas. There's a ''reason'' that humans are the apex predator of most any place they congregate, and our "range", unlike other animals, is "wherever the hell we want to be".\\\
Especially when augmented with our other abilities, "see really well (but only in the daytime, only for a relatively short range, and at the expense of smell)" and "can walk or jog for a really long time without getting tired," which combine to make humans some of the ''most'' persistent (and effective) [[SuperPersistentPredator Super-Persistent Predators]] on the planet. [[UpToEleven And that was]] ''[[UpToEleven before]]'' [[UpToEleven we domesticated dogs to make up for the smell weakness...]]
* A gun with blanks. Blanks are only safe from a few feet away from the barrel.
** In 1984, on the set of the short-lived CBS series ''Cover Up'', actor Jon-Erik Hexum got bored between takes and played RussianRoulette with one blank in his gun. A blank does not have a bullet, but has plastic and paper places in it -- the propelling charge is all there. He died from his injury.
** This was also how Brandon Lee died on the set of ''Film/TheCrow''. Owing to the film's TroubledProduction, the prop crew, rather than spend money on "dummy" cartridges for close-up shots of the revolver used to shoot Lee's character, created some on the cheap by taking actual, live .44 Magnum rounds, pulling the bullets out of the cartridges, dumping out the powder, and reinserting the bullets. However, they forgot to take out the percussion primers, which went off with just enough force to lodge a bullet in the gun barrel. When they loaded that same gun with blanks, the force from the shot sent that bullet flying out the barrel and straight into Lee's chest at close to full speed.
* Physicists have noted that ''any'' form of FasterThanLight drive would be as devastating a weapon as it is a useful tool. Even leaving aside the various exotic wedgies you're giving to physics, there's still the fact that, as stated in ''Franchise/MassEffect'', Sir UsefulNotes/IsaacNewton is the deadliest SOB in space (check out the page quote for ArbitraryMaximumRange for why this is so).
** The net result of this was demonstrated in ''Film/TheLastJedi'', where a hyperdrive is used to turn a frigate into a million mile an hour battering ram. It not only cleaves The First Order's capital ship in two, the debris travels fast enough to replicate the effect ''on all the ships behind it''.
* Many [[InsistentTerminology less-than-lethal]] weapons can inflict substantial injuries or even kill if they're misused.
