* In ''DigimonTamers'', [[DirtyCoward Makuramon]] decides it would be a great idea to show up and taunt [[PsychoForHire Beelzemon]] over the latter's troubles with fighting [[RealityWarper Megidramon]], ''while he's fighting Megidramon''. [[SarcasmMode 'Cause pushing the]] BerserkButton [[SarcasmMode on a guy with a]] HairTriggerTemper [[Sarcasm Mode who's already a]] ''[[SarcasmMode lot]]'' [[SarcasmMode stronger than you is totally a good idea]]. Never mind the fact that said guy kills Digimon to absorb their strength and currently needed a boost to beat Megidramon.

** Also in ''Manga/DevilmanLady'', [[spoiler:Jun's girlfriend Kazumi]] dies when she leaves her hiding place for no good reason whatsoever.

* Loly and Menoly from ''Manga/{{Bleach}}'' are two Arrancar {{Clingy Jealous Girl}}s who aren't happy to see their boss, Sosuke Aizen, bring a young woman from Earth, Orihime Inoue, as a part of his GambitRoulette. What do they do? Go torture the girl out of jealous, only to be mauled by their superior. Then, after [[spoiler:Orihime shows [[TheMessiah Messiah traits]] and revives/heals them out of pity]], what do they do? After a while, they try to kill Orihime ''again'' and then use her as a hostage ''in front of Ichigo and Ulquiorra''.
** Loly goes so far to claim that she's going to kill Yammy and Ulquiorra, two of the Espadas while she has no special combat ability of her own [[spoiler:even if she most likely didn't know about Yammy being Espada #0]].

*** [[spoiler:Not that they'd be able to anyway; it takes them until they're walking around the modern-day world to realize they haven't aged in about 70 years, and are thus also immortals.]]

* ''{{Manga/Tytania}}'': Duke Idris Tytania [[spoiler:betrays another member of the clan he was sent to rescue, and stands by to watch while the enemy destroys his ship, presumably killing everyone on board, including Idris's subordinate, Berthier, who ''thought'' he was in on Idris's plans. Berthier actually manages to get to an escape pod and survives, though he is permanently crippled. Then, although he is presumed dead and could easily just take off, ''he goes back to continue serving the guy that just double-crossed and tried to kill him.'']] Yeah. [[SarcasmMode That works out real well for him, as you'd expect.]]

* ''Anime/YuGiOhGX'': [[IdiotHero Protagonist Jaden/Judai]] nearly dooms the world by [[spoiler:handing over the key to a KillSat]], then expecting that Season's BigBad to not activate it until after defeating Jaden in a [[SeriousBusiness children's card game]] first. The fact that said BigBad didn't attempt to duel him first was a shock to many fans, as Saiou was the probably the first GenreSavvy villain in ''Yu-Gi-Oh!'' history.

** [[spoiler:Hansel. They made him too aggravated to think and he walked willingly into a trap.]]

* The {{Red Shirt}}s from the battle against Teppelin in ''Anime/TengenToppaGurrenLagann''. [[spoiler: Our leader has just obliterated himself against the mysterious shield surrounding our enemy's city? Quickly! More of us must ram into it so that his death will not be in vain!]]

* The torturer in ''{{Manga/Berserk}}''. Thinking that he has the upper hand because he locked the most dangerous enemies of his kingdom (aka the main characters) in a dungeon room, he proceeds to hang around to taunt them. When Guts slowly stands and asks in an unnervingly quiet and soft voice if he was responsible for [[spoiler:Griffith's mutilation]], the torturer pays no heed and proceeds to describe exactly how he tortured him over the past year, finishing by showing them his crowning jewel: [[spoiler:[[BerserkButton Griffith's severed tongue,]]]] worn as a necklace. His death is brutal, quick and horrifically painful. Worse, he brags how [[TemptingFate nothing they do will succeed]], because the door is three times thicker than any normal door. Too bad he never took Guts' [[{{BFS}} weapon of choice]] into account...

** [=Frieza=] has been sliced in half, near dead, and was given a sliver of Super Saiyan Goku's power to survive on as an act of mercy. And what does he do with it? He tries to use it to kill the Super Saiyan from behind, despite the fact that it most likely wouldn't have made a dent. Needless to say, it doesn't end well for the tyrant. [[UnexplainedRecovery He got better]]. [[spoiler: Only to get KilledOffForReal by Future Trunks.]]

** Nunnally herself also counts. She is more in the right mind, and position, than Suzaku, as governess of Japan, not to mention the ability [[LivingLieDetector to detect lies]]. Not using the latter on Schneizel, who [[spoiler:lies to her about Lelouch and Pendragon being evacuated, and later [[UnwittingPawn uses her as a pawn in his latest plan]] with no aversion to abandoning her]]: big mistake.
** Ohgi [[LoveMakesYouDumb gets so caught up in his relationship with Villetta]] that he is responsible for several rash decisions which he walks away from through sheer PlotArmor, and is [[UnwittingInstigatorOfDoom chiefly responsible for]] [[spoiler:leading the other Black Knights to [[TheMutiny betray Lelouch]] after being fooled by both Schneizel and Villetta's testimonies]].

** Joseph Greer [[spoiler:fatally shoots Alyssa with Miyu nearby]], but does not run away immediately afterward, instead announcing his intentions for doing so. Within moments, [[spoiler:an enraged Miyu kills him]].
** During her confrontation with Shizuru, Haruka not only [[BerserkButton unnecessarily insults Natsuki]], but continues to insult Shizuru ''even as her Element is drawn'' rather than stop provoking her or run away as Yukino suggests, thus forcing Yukino to try to defend her, leading to [[spoiler: the destruction of Yukino's CHILD Diana, and Haruka's own death]].
** When Nao first encounters Shizuru while attacking Natsuki, she is easily defeated. In response, she kidnaps Natsuki again, this time ''for the express intention of luring Shizuru out''. To make matters worse, by this time, [[LoveMakesYouEvil Shizuru has gone insane from Natsuki's rejection]], and [[spoiler:not only destroys her CHILD Julia, but tries to finish off Nao before Natsuki intervenes]].
* [[MusicalAssassin Kanaria]] from ''Anime/RozenMaiden'' has some shades of this during the series, but it becomes blatant obvious during the final battle of the second season: [[spoiler:not only she is the cause of turning Suiseiseki's HeroicSacrifice in a SenselessSacrifice by going back to the battle field, she also is killed by Barasuishou after the strings of her violin snaps and she forgets that, since she has Suiseiseki's [[AnatomyOfTheSoul Roza Mystica]], she could use her GreenThumb powers]].

* ''FairyTail'': Mirajane and [[spoiler:her [[NotQuiteDead not quite]] {{dead little sister}} Lisanna]] are battling Azuma, a BloodKnight opponent who appears disappointed by his two supposedly weak opponents until [[spoiler:Lisanna]] boasts that Mirajane is the famed "[[RedBaron She-Devil]]" Mirajane who only becomes strong when using her Satan Soul transformation (which Mirajane clearly said she is refraining from using because she's low on magic power). So Azuma makes Mirajane do just that...[[spoiler:by [[TryingToCatchMeFightingDirty strapping Lisanna to a bunch of explosives and giving Mirajane three minutes to beat him before they explode]], which leads to Mirajane making a HeroicSacrifice to save Lisanna from the blast. So Mirajane, one of the strongest fighters at Fairy Tail's disposal during a time when they need as many strong fighters as they can get, nearly gets herself killed thanks to her sister's underestimation of their opponent. Fortunately for Lisanna, [[MyGodWhatHaveIDone she realizes just how stupid it was of her to do that]] and wises up.]]
** Something similar happens not long after, though in this case, it's more like "Too Dumb for Everyone Around Her to Live". Before Grimoire Heart came to attack, Fairy Tail was in the middle of an exam that Cana was taking very seriously to the point that she threatened to leave the guild if she failed. So what's the best thing to do when a bunch of uber-powerful opponents have come to fight, inadvertently interrupting the test in the process? According to Cana at the time, it's continuing to take the test as if there weren't any enemies to begin with, instead of helping her friends fight when some of them are falling left and right. To her credit, she didn't realize that some of her friends have already fallen, but what does she do next? [[spoiler:After Lucy gives her a lead on how to pass the exam, ''[[YouHaveOutlivedYourUsefulness she knocks out Lucy and abandons her to do just that]]''. And this is while knowing that there are enemies powerful enough to kill them wandering around. And Lucy ''would have'' been killed if she hadn't woken up at the last possible second. Again, to Cana's ''slight'' credit, she ''did'' try hiding Lucy out of sight from potential enemies. But that didn't stop Lucy from being found anyway.]] Similar to the above example, however, [[spoiler:[[MyGodWhatHaveIDone Cana eventually recognizes her own idiocy]] [[BigDamnHeroes and rushes to her friends' rescue]]]].

** Played straight during his fight with Eneru: Eneru can read his mind, so he tries to fight back ''without thinking'' '''''AT ALL.''''' For a while, it works, but it gets so bad, he actually spaces out mid-fight!

** Envy himself qualifies. He went on a huge rant about how he was the one who killed Roy Mustang's best friend, and almost hurt himself from laughing about it. Keep in mind, Envy went out of his way to tell how he was also the one who started the Ishval War and how amusing it was to see such a huge battle over the death of one little girl that it killed. Envy finds himself [[KillItWithFire on fire about two seconds later]].

* Right, [[HigurashiNoNakuKoroNi Keiichi]] go into that creepy basement with self-confessed psychotic murderer. Nothing bad will happen. And after you survive that, feel free to go out in the [[IdiotBall dead of night to chat with her]].

* Many, if not all, of the characters in ''Manga/RanmaOneHalf'' get at least one occasion where they act like this. However, this trope gets played to its actual conclusion in one late-manga story, which really makes it into MoodWhiplash. One character's father receives a scroll detailing a martial arts style which makes use of a lot of brute-force tricks, a bearhug attack explicitly stated to be capable of snapping a man in half. Kumon Senior intends to use these moves to revitalise his dojo, which is dilapidated to the point it's being held aloft only by a single, rotting pillar, but he decides to master this spine-shattering bearhug by '''practicing on the pillar'''. Naturally, when he succeeds in learning it, the whole house collapses on top of him, killing him.
** In the second movie, the monkey guy who uses his super-cool psychic attack of soul-crushing despair.....on [[AngstNuke Ryouga]]
*** Though that's partially justified, as he had no idea Ryouga was empowered by depression, and against anyone else it woul have been a GameBreaker.

* ''Anime/DeathNote''. The fiancée of the recently murdered F.B.I. agent figures out crucial information on the Kira case and then decides to trust [[AloneWithThePsycho Light]] with it after he's been acting creepy, following her around, and asking "HaveYouToldAnyoneElse?" Incidentally, she decides to trust Light because he reminds her of L, lampshading that the two are NotSoDifferent.

** Pretty much every Z-Fighter except Goku, particularly the human ones. While it may be somewhat justified by their Determinator natures, how many times do they have to be killed and/or nearly killed trying to fight the current villain only for Goku (possibly Gohan) to show up and beat the guy before they figure out it's probably better to not even bother. Heck, Future Trunks history (where Goku dies of a heart virus and all but 1 of the Z-Fighters are quickly killed by the next big villain) practically lampshades this fact.
