History Main / LethallyStupid

--> '''Electrochemistry:''' From the void we came. And to the void we must return!

* ''WesternAnimation/FamilyGuy''.
** {{Two words|AddedEmphasis}}: Peter Griffin. He is so dangerously stupid he even burned down a children's hospital, by accident!
** In "[[Recap/FamilyGuyS13E8OurIdiotBrian Our Idiot Brian]]", Brian gets a brain tumor that made him as stupid as Peter, and Stewie had to trick him into getting it surgically removed because he couldn't bear to see him endangering his life with his stupid antics.

* ''WesternAnimation/RegularShow'': Rigby tends to instigate life-threatening anomalies from simple, mundane subjects. Like unleashing a destructive video game monster when he was warned not to cross the wires.

* Major Frank Burns is an officer who should not even be entrusted with a courtesy sidearm, as every time he picks up his handgun, it is a danger to himself and people around him; he has not got the hang of even elementary weapons safety. And in one episode of ''Series/{{MASH}}'', he gets into an unattended ''tank'', thinking a short course in armoured vehicles makes him an expert driver. A thirty-ton tank that Burns discovers he can neither control nor stop then destroys several tents, breaks up a poker school, and [[ArsonMurderAndJaywalking crushes]] Colonel Potter's [[BerserkButton personal jeep.]]

* This the point of ''Series/OneThousandWaysToDie'': many idiots are responsible for killing other idiots.

* ''WesternAnimation/TheAmazingWorldOfGumball'': Richard Watterson due to his BumblingDad personality, he can cause disasters by accidents. In one episode, he causes TheEndOfTheWorldAsWeKnowIt by getting a job as a pizza delivery man.

* London Tipton in ''Series/TheSuiteLifeOfZackAndCody''. Just watch the episode "Orchestra" and you'll see what we mean.

* ''Franchise/ThePinkPanther's'' Inspector Clouseau will either destroy your property, his own, make you insane, or cause your death. All this out of pure clumsiness.
-->'''Dreyfus''': Compared to Clouseau, this doomsday machine is just a water pistol.
* Wherever Film/TheThreeStooges go, disasters are in the air. Just compare the setting and characters looked like before and after these three showed up. Hell, in real life, they'd be accidental mass murderers and most likely dead a dozen times over.

* ''Film/JuanOfTheDead'': Lázaro. He manages to accidentally kill non-zombified people like [[spoiler:Yiya, and Preacher Jones, just before he reveals his plan to deal with the zombies]].

* ''Film/{{Predators}}'': [[Characters/{{Predators}} Edwin]] is not really useful even with his medical knowledge and [[spoiler:gets himself killed when he decides to target his allies because of his sociopathic tendencies.]]

* The TropeCodifier is Lumpy from ''WebAnimation/HappyTreeFriends''. You want to know how dangerous this moron is? He has a higher kill count than Flippy, who has an AxCrazy SuperPoweredEvilSide!

* Many reviewers are this in ''Website/ThatGuyWithTheGlasses''.

* This trope is the entirety of Team Magma and Team Aqua's plans in ''VideoGame/PokemonRubyAndSapphire''. At no moment the game ever denies the fact their plans make no sense, and that they are going to bring anything but the supposedly beneficial effects their plans are meant to bring, but the fact these teams have the resources to pull off those plans are what makes them threats in the first place.

* Patrick Star of ''Franchise/SpongeBobSquarePants'', hands down.

* Pictured above is the poster boy for this trope, Gordon Frohman from ''WebComic/{{Concerned}}''. Frohman wants to try his hardest to become an esteemed member of the Combine and be recognized as the biggest traitor to humanity, but unfortunately, he only ends up aiding the Resistance by virtue of his actions only causing untold amount of Overwatch and Civil Protection casualties and attaining victories for the resistance which makes one wonder why nobody within the Combine decide to send him to Nova Prospekt for his failure. Even outside of the Combine, he only succeeds in aiding the opposing team to win.

* The IOA in ''Film/StargateTheArkOfTruth'' nearly dooms ''two entire galaxies'' in an inept attempt to stop [[AGodAmI the Ori]]. The main cast is on a dangerous mission to enter Ori space in a ship with an advanced cloaking device. But the IOA has an agent on the ship who uses its advanced alien computer to create a [[GreyGoo Replicator]]- an extremely dangerous mechanical insect species able to infect and assimilate any technology they come across. His use of the computer core to create the Replicator exposes the ship the Ori. And he modifies the Replicator so that it's immune to the best weapon the team has to destroy it, which he ''does not mention'' until after they drop the shields around the thing so they can shoot it- meaning the Replicator immediately escapes and infects the ship. And the Replicator's infestation of the ship cripples its systems, meaning the cast is helpless when four Ori ships arrive to take turns pounding away at it. It's rather hard to sympathize with the guy when the Replicators wind up killing him and driving his corpse around.

** In ''Breaking The Ice'' Trip and Reed end up in danger when investigating a comet. The Enterprise cannot save them, but there is a more technologically advanced Vulcan ship nearby. Archers refusal to call them is not a "We must learn to not depend on the Vulcans" stance, but rather his refusal to ask for help from those [[FantasticRacism goddamn Vulcans]] as a point of [[HonorBeforeReason pride]]. Possibly justified, because the Vulcans are known to use any excuse they can to convince the top brass to scrub ''Enterprise's'' mission.

* ''Film/JuanOfTheDead'': Lázaro. He manages to accidentally kill non-zombified people like [[spoiler:Yiya, and Preacher Jones, just before he reveals his plan to deal with the zombies]].

* ''[[WebVideo/OutsideXbox The Oxventure]]'' has the Oxventurers Guild, but especially Dob the Half-Orc Bard, whose well-meaning but reckless actions often fail to consider the consequences and land the Guild in hot water. In one particular instance, his well-meaning attempt to use a magical hammer to construct an orphanage leads to several deaths, while in another, his attempt at a FastballSpecial leads to Merilwen being injured and the death of a friendly NPC.

* ''Machinima/RedVsBlue'': Private Michael J. Caboose is one of the stupidest people in the galaxy. He is also famous for getting the first kill in the entire series... on his own team leader. He has gone on to accidentally kill so many of his teammates that Command has installed a keyboard shortcut to report his teamkills.

** Goku tends to care more about having a [[HonorBeforeReason fair]] and [[ChaoticGood challenging]] fight than anything else. He allows his most dangerous opponents to power up their maximum level even when the entire planet's at stake, and even gives Cell a Senzu Bean right before he was about to engage in a fight to the death ''with his son''. He also has the habit of giving his enemies a LastSecondChance when he ''really'' should just kill them and be done with it, (although this only causes trouble with Raditz and Frieza, since everyone else Goku spares turned good eventually). This comes to a head in ''[[Anime/DragonBallZResurrectionF Resurrection 'F']]'', where he gives Frieza the opportunity to walk away ''again'' despite how badly it backfired for him the last time; not only does Goku get near-fatally shot for the trouble, but when Frieza was subsequently defeated by Vegeta, he flipped out and [[spoiler:blew up the Earth]].

* The plot of ''Series/MobCity'' is kicked off by Hecky Nash trying to blackmail Ben "Bugsy" Siegel with photographs that show Siegel killing a man. Hecky is so blinded by his hatred and contempt for the mobsters that he does not care that [[TooDumbToLive he is pretty much signing his own death warrant]] and that of everyone connected to the scheme. By the time the first season is over, almost everyone involved is dead [[spoiler:-- including Hecky and Siegel]].

* This trope is basically the entirety of Team Magma and Team Aqua's plans in ''VideoGame/PokemonRubyAndSapphire''. At no moment the game ever denies the fact their plans make no sense, and that they are going to bring anything but the supposedly beneficial effects their plans are meant to bring, but the fact these teams have the resources to pull off those plans are what makes them threats in the first place.

* ''WesternAnimation/BeavisAndButtHead'', so very much. Most of their misadventures result will result in massive collateral damage and often injuries to supporting characters and bystanders. This comes to a head in TheMovie, ''WesternAnimation/BeavisAndButtHead'', where they unwittingly cause more chaos, bodily harm and destruction in one trip across the country than most ''terrorists'' do in a lifetime. It's never out of malice, but just because they're too stupid to fully comprehend the ramifications of, well, pretty much anything they're doing.

** [[IdiotHero Homer Simpson]] is definitely not someone you'd want to see in a nuclear center. DependingOnTheWriter, Homer's stupidity can either cause mere property damage, or actually hurt people, and even make them insane (poor Frank Grimes... and prior to burning out, he points out that ever since Homer took over as safety inspector, the plant's accidents and near-meltdowns have ''tripled''). In the Halloween episodes, he is often seen killing others because of his idiocy.

* In regards to technological health; a script kiddie is a person who uses existing computer scripts or code to hack into computers, lacking the expertise to write their own. Such people are often considered more dangerous than a hacker, because at least a hacker has some idea of what they're doing. On the rare occasions that they manage to destroy something important by pure accident, a hacker usually has sufficient knowledge to fix whatever it was they broke, even if they have to resort to a scorched-earth format-and-reinstall. A script kiddie, meanwhile, has no idea how the system actually works; they just use someone else's code and expect it's going to work. When something happens that they didn't mean to, they'll have no idea what to do, and could potentially cause irreparable damage.
* The [[https://en.wikipedia.org/wiki/Goiania_accident Goiânia accident]], while partly the result of people not knowing the risks of fooling around with radioactive materials, is also the result of plain stupidity, stupidity that left a final death toll of 4, plus 249 contaminated survivors, and over 112,000 people in the city of Goiânia checked for radiation sickness. When scrappers broke into a derelict hospital and stole a radiation source from a radiotherapy machine containing radioactive cesium chloride, things already started to go wrong when the two men began to suffer nausea and began vomiting while disassembling the device. The second of the two men kept going at the machine while the first went to seek treatment, and he eventually smashed his way into the device and got some of the cesium chloride out. After selling the device to a nearby scrapyard, things only got worse, to sum it up.
* General Custer, a 7th Cavalry General who lead his men into a massacre with absolutely no battle plan whatsoever. Infamously, not only did he get himself killed, he got all of his men killed as well.
* Driving under the influence, whether of alcohol or drugs. Impaired judgement plus a few thousand pounds of metal traveling at high speeds equals high probability of tragedy for anyone unfortunate enough to be in the idiot's path.

* ''FanFic/TheInfiniteLoops'': This is the only reason [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Billy]] is considered an MLE – he's so stupid that he's a danger to himself, other Loopers, and Yggdrasil as a whole. He managed to kill several near-omnipotent Loopers, cause another potential insane person to go ''temporarily sane'' and shoot him, and crash '''''[[BeyondTheImpossible three safe-mode punishment loops through his sheer idiocy]]'''''.[[labelnote:Note]]For those who don't know, safe mode loops [[BroughtDownToNormal lock looper powers to baseline abilities]], [[RailRoading force the loopers to go along with the universe's plot]], and are considered some of the most stable and impossible-to-crash loops in all of Yggdrasil... This did not stop Billy from accidentally finding a way through sheer idiocy.[[/labelnote]]
