History WhatAnIdiot / AnimeAndManga

* ''Anime/BlueExorcist'': Late in the story, we see the story of how protagonist Rin Okamura and his twin brother Yukio, the halfbreed sons of Satan, came to be. [[spoiler: The boys' mother somehow comes to understand that not all Demons are evil. Satan kills many men in an effort to take form and experience life, but when he approaches her for the same cause, she opens herself willingly. They spend time together, fall in love, dream about a world where Humans and Demons can live together in peace, and make some babies. She dies soon after the birth, and the twins are adopted and raised by a priest.]]\\

'''Instead:''' She abruptly decides to betray Madoka and steal her goddess powers to trap her and everyone else in a LotusEaterMachine so she can have Madoka to herself and protect her, [[DickDastardlyStopsToCheat which is literally what she was about to get anyway]].

'''Instead:''' He ''forgets'' by telling Kazuha that they should go home, much to Conan and Ran's shock. Only once he and Kazuha are taking a train home does he realize his blunder, {{facepalm}}ing out of dismay.

** At the end of Chapter 1118, Ran helps Heiji and Kazuha find "the moment" for the former to finally confess his feelings for the latter.
'''You'd Expect:''' For Heiji to realize it and that there is no one or nothing to interrupt his attempt.

** Yui is married to Gendo, someone who is implied to have had an even worse backstory than his son Shinji and knows she acts as his LivingEmotionalCrutch and seeing as he and Shinji are all but outright stated to be not so different, so eh cannot connect to people. And then she has a kid with him, something that would make a social confident man extremely nervous, let alone a man whose mental state is about as stable as a Jenga Tower with half of the pieces missing. All of this Yui knows as she's working on the Eva pilot.\\

'''You'd Expect:''' Ippo to wear dow xn his opponent as best he can, before surprising a tired Sawamura with the modified dempsey roll.\\

** In Episode 13, "Night of the Tamayura", Yuuichi and Shiho are out on a date, and they bump into Mai and Reito just as they're [[WillTheyOrWontThey about to kiss]]. He's [[CannotSpitItOut still struggling to decide]] whether or not he actually likes Mai "in that way".\\

** A wealthy rancher tells the protagonists that he will sell back an ill-gotten heirloom in exchange for them killing an unusually clever bear that has been preying on his horses. However there's a catch: this is an immortal bear, that regenerated an eye and claw that were shot off the previous year.\\

* ''Dawn of the Silver Dragon'': BigBad uses technology which can turn any woman into a [[HappinessInSlavery willing sex slave]] with MoreThanMindControl and uses it for profit (or so it seems).\\
'''You'd Expect:''' Formation of elite, male-only force dedicated to stopping the threat, perhaps using some additional privileges to put the villain down. You know, something like ''Film/TheUntouchables''.\\
'''Instead:''' A female-only police group is hunting the guy. To add to the idiocy, one of the high-ranking officers was a former victim of the aforementioned technology. And if that's not enough, the leader of the unit willingly lets herself be captured as part of a bait operation, with only one person as backup. It may be hentai, but nothing excuses levels of idiocy that high.

* ''Manga/GoldenKamuy'': A wealthy rancher tells the protagonists that he will sell back an ill-gotten heirloom in exchange for them killing an unusually clever bear that has been preying on his horses. However there's a catch: this is an immortal bear, that regenerated an eye and claw that were shot off the previous year.\\

'''You'd Expect:''' Ippo to wear down his opponent as best he can, before surprising a tired Sawamura with the modified dempsey roll.\\

* ''Manga/GiantRobo'':

'''Instead:''' Nami's sisters completely ignore her problems, which gets exacerbated by the the fact that [[TheUnfavorite Nami's oldest sister Kazane clearly favors her sister Akiha over her]]. \\

* ''Manga/RonKamonohashiDerangedDetective'': In the Island Observatorium Murder Arc, Grizzly figures out who the murderer is by finding a fishing line in the telescope room.

** Canaan and Maria rode the tram inside the flashing tunnel. There were two other people in there with them and one looked rather shady. Suddenly lights went out.
'''You'd Expect:''' Canaan to stay put and protect her friend.

'''Instead(!!):''' They drop the nuke right on 01. The machines survive.

'''Instead(!!!):''' They cover the entire surface of the planet. [[TooDumbToLive Did they forget that all the things humans need to survive also require the sun]]? Even if they had one, they basically ensured their own near-extinction unless they assumed they would win inside of a week.\\
'''Even Worse(!!!):''' The assembled leaders actually applaud this solution like it's a good thing. Then it cuts to a regiment of ground troops suiting up for a big final battle against the machines and receiving condolences from Buddhist and Christian monks as the 'Dark Storm' bombers fly across the sky filling it up with nano-bots while the narrator reads: 'May there be mercy on man and machine(!?) for their sins'.\\

'''Instead:''' Envy shapeshifts into ''Hughes'', thinking that Mustang "won't kill his friend". Sound logic, Envy... [[DidntThinkThisThrough except for the fact that said friend is dead and Mustang now knows for a fact that they are dead because of]] ''[[DidntThinkThisThrough you]]''.\\

** Tenma is called to operate on Johan, who has been shot in the head. Director Heinemann then learns that the city's mayor has suffered a blood clot. He asks Tenma to switch to the mayor, but Tenma says that Johan arrived first and his surgery will be very complex, and only he can pull it off.
'''You'd Think:''' Heinemann would accept this and have some other doctor handle the mayor. Since the hospital is already being protested over a previous incident that resulted in the death of a Turkish patient, they can't afford any more bad publicity, and the story of the Liebert family's escape from East Germany is all over the news, so it would be very bad for the hospital's image if they negligently allowed Johan to die.

** Richard Braun is investigating a number of murders and suspects Johan is behind all of them. One night, he is on the phone with his daughter when Johan suddenly arrives at the door and asks Richard to go out to a bar so he can interview him for a school report.
'''You'd Expect:''' Richard would realize that going out alone at night with a likely serial killer is a bad idea, and politely refuse. Or if he does go with him, he would first tell Dr. Reichwein, who knows about Johan, what's going on.

* ''LightNovel/BakaAndTestSummonTheBeasts'': In the finale, [[IdiotHero Akihisa]] uses his one request to the school to give [[TeenGenius Himeji]] a second chance to take the admission test so she can go to the A-Class (for geniuses) instead of the F-Class (for idiots) she was stuck in due to fainting during the original test.\\

'''The result:''' Jimuru is so enraged by this accusation that he storms out and [[ThenLetMeBeEvil gathers up his gang and has them cause more trouble than ever before]]. By the time the shopkeeper is convinced to look for the coin, it’s too late. [[SarcasmMode Nice going, jackass.]]

'''Instead:''' The dumbass pulls his sword aside, lies on the ground and whines that he can't kill his best friend, which causes Kassim to hit him and stab himself to death, creating a huge Dark Djinn (monster) who's so strong even Sinbad and Morgiana can't kill it. This also causes Judar to go crazy with power. Nice job breaking it, you freaking dumbass.

'''Instead:''' Hakuryuu rants and screams, causing Hakuei to hit him and think he's lost his mind. Which leads Hakuryuu to fall into depravity upon meeting Judar. Nice job, Hakuei.

'''Instead:''' [[UnusuallyUninterestingSight They act like it's just another day,]] ([[FridgeHorror and they're the SVU, which is the biggest crime in the setting!]]) and [[IdiotHero Ageha]] goes on to become a combination TheMillstone, ManchurianAgent and UnwittingPawn even before the MindControl aspects of the drug when she's [[ADateWithRosiePalms masturbating at crime scenes]] then turning the ''entire police station'' into a Roman orgy for the BigBad to lord over before an AssPull saves though though [[KarmaHoudini escapes as a Sequel Hook.]]
