History NightmareFuel / Doraemon

''Doraemon'' may be mostly light-hearted, [[DarthWiki/NightmareFuel but some elements may keep you up all night]].

* Heck, some of Doraemon's gadgets can be downright scary at times. For instance, the Dictator Switch allows its user to make anyone disappear. And not just out of sight, the person is gone and no one will ever remember that person even existed... yes, even the person's own mother. And in the chapter this gadget debuted in, Nobita wound up making EVERYBODY disappear. Granted, the device is used to punish dictators and the effects are reversible but the fact that this device is sold to the public, it is very chilling.

** The last dream before the whole scene falls part deserves its own mention: Nobita finds himself in a barely lit corridor looking at a TV that shows [[MindScrew Nobita looking at a TV that shows Nobita looking at a TV...]] while his family laugh hysterically at him. Like the above scene with Doraemon, it's a genuinely creepy scene that would be more typical of a psychological horror anime than the lighthearted slice of life Doraemon usually is.

** It's also one of very few instances in the series where FamilyFriendlyFirearms were averted. In addition to machine gun above, Doraemon also gives Nobita and his mom futuristic but ''realistic'' looking revolver and rifle respectively to help him hunt the mouse. To make it worse, Doraemon then proceeds to explain the details of those two weapons, which boils down to the fact that these weapons were made to ''kill''. That's right kids, our cat robot had just given two untrained civilians what basically the 22nd century counterparts of the Desert Eagle and AR-15. Needless to say, the Nobis were completely freaked out by it.

* Crossing with Awesome and Funny, in one of the older episodes, Doraemon and Nobita go to WWII and in order to help a jew family, the cosmic robot is forced to use some pills to pass [[https://www.youtube.com/watch?v=Ikx33ATv9O8 as Hitler]], yup, literally.

* In one episode of the 2005 anime, Nobita is sent to bed early, so Doraemon gives him a gadget that will let him choose a dream. The problem is, his short attention span leads him to keep changing the cartridges mid-dream, and in one of them, after he can't wake himself up, he finds a floating Doraemon with a [[MoodDissonance dissonant smile]] and blank eyes. He asks him for help, and he responds, with an ElectronicSpeechImpediment at that, at least in the dub, something to the effect of; "The ''pla''yer is ''bro''ken, Nob''y''. ''You'' br''ok''e it. And n''o''w you're stuck in this ''dream'' for''ever and'' '''e'''ver, No''by''." After that, things just keep going downhill, with Nobita jumping through all of the dreams he switched between, all with little details being just off enough to be unsettling, until he breaks down crying in an endless void. It turned out that he wasn't actually waking up and changing dreams. It was a SecretTestOfCharacter from the first dream he chose -- an educational dream that was trying to [[ToughLove teach him a lesson]] in following a goal from start to finish.

** Then there's the Passport of Satan. What does it do? Well, it lets you get away with anything... and I mean anything. Granted, in the story, Nobita felt guilty after for what he had done when he used it but... remember that in the future, the gadgets are sold to the public which includes the Passport of Satan... you make the connection.

** Then there's the Devil Passport. What does it do? Well, it lets you get away with anything... and I mean anything.

* "The Human Manufacturing Machine", especially the version from the 1979 anime. The idea of a gadget that can make ArtificialHumans out of mundane household objects already ups the creepiness factor, but it gets worse when Doraemon reveals that the gadget was discontinued because it had a defect that led to the production of superpowered mutants, who plotted dominance over regular humans. By the time Nobita finds out about this, it's too late, and the machine has grown a [[https://i1.read01.com/oEwqrjuj9ypIc5wgo7-b5ho/0.jpg mutant baby]], shown to be an imp-like creature with GlowingEyesOfDoom. It uses its superpowers to knock out Doraemon, force Nobita to bring it milk, and when Shizuka visits, immediately tries to ''kill her'' for no apparent reason.[[note]]In the manga, this is a reaction to her accidentally breaking the milk bottle Nobita was bringing to it[[/note]] Who knows what would have happened if Doraemon hadn't recovered and rewound time just then! And just as one last scare, the EyeCatch after the episode shows ''Doraemon'' [[https://imgur.com/a/EYbnH3j growing inside the Human Manufacturing Machine]], with his eyes [[GoodEyesEvilEyes turning into a glowing pair like the mutant baby's]].

* In ''Nobita's New Dinosaurs'', the gang looks up to see what looks like a shooting star falling to Earth and causing an explosion in the distance, which Doraemon realizes is the meteor that caused the Cretaceous extinction event. What follows is his chillingly realistic description of the results of the impact, with dinosaurs being vaporized within the blast radius and laying dead from the clouds of dust caused by the blast causing global cooling and a worldwide food chain collapse.
