* While this is more of a FridgeHorror, in the episode "Fizz Ed", Ms. Angela Li demonstrates quite psychotic behavior, to the point of being AxCrazy; the FridgeHorror is that if you think about it, who knows what Ms. Li would have done with the ax if she had not stopped. Note that until she was transferred by ambulance.
* The vast majority of any nightmare fuel in ''Daria'' is neatly imprisoned within the confines of the pilot episode. For one thing, there's Daria's [[http://static.tvtropes.org/pmwiki/pub/images/daria_smile_7410.gif disconcertingly toothy grin]] (no wonder she rarely, if ever, smiles in the actual series), and for another, [[http://static.tvtropes.org/pmwiki/pub/images/brittany_2752.gif Brittany]] (''every'' shot of her is that horrifying).
** It's the first and only time that Daria ever smiled with her teeth for a reason.
* The "Hall of Mirrors" in Daria's nightmare in "Through a Lens Darkly". What starts off as innocent hall of mirror fare ends up with some of the most grotesque animations seen in the show (see image).
* The UrbanLegends told in "Legends of the Mall", particuarly the one which casts Mr. De Martino as a shop teacher driven to madness by the stupidity of his class, resulting in the loss of his teeth which he replaces with [[http://www.theangstguy.com/images/metalmouth.jpg metal ones himself]]. The way he just takes a chunk out a door is especially disconcerting.
*** Woe betide you if you enter the "Legends of the Mall" or Metalmouth pages on The Daria Wiki...
** ''The Rattling Girl'' (the story of the girl from the 1960s who looks like Sandi who became so skinny that her bones rattled when she danced). *shudder*
** Worse one was the Grade Changing girl. It was bad enough Daria played the part in her own urban legend, what made it scarier was that she laughed evilly comparable to Mr. [=DeMartino=].
* While on the subject of Mr. [=DeMartino=], his two EvilLaugh moments are rather creepy, especially as both are directed towards the viewer and are shown in an ominous shade.
* The sushi parasite that's pulled out of Jake's mouth.
* Daria's family, when they eat the psychotropic berries when they go camping... ''their eyes''...
** And before that, Daria's BloodierAndGorier retelling of ''Literature/HanselAndGretel'' in the campfire gives the viewer a close up of Daria [[ScaryShinyGlasses with the reflection of the campfire showing in her glasses]] as Daria tells the tale.
* It was PlayedForLaughs in context, but something feels creepy about Daria's nightmare in which she and Jane become as ditzy as the Fashion Club. Much of this feeling relates to the fact the nightmare showed Daria conversing with three girls who each had the same face and hairstyle as Jane, but spoke with a voice belonging to one of Quinn's friends. Also, none of them find this a strange sight because they spend so much time talking about ''pores''.
* The beginning of "Boxing Daria" is a completely black screen, followed by the sound of a car crashing and a voice asking "Miss? Miss? Are you alright?" We find out later that [[spoiler: Daria's fine and nobody got hurt, but it's still scary.]]
* Some of the Alter Egos can be creepy, such as, fittingly, one of Mr. [=DeMartino=] as a deranged and roughed up man biting the heads off animals. Other examples include Stacy as Literature/{{Carrie}} and Sandi as the Devil.
* The Sarcastathon 3000 intro to "The Lawndale File" features Daria and Jane in rather ridiculous [[GreenSkinnedSpaceBabe alien getup]]. But then Daria comments "Enjoy it, because tomorrow, you will be our slaves" in a surprisingly ominous tone.
** While on the subject matter, another intro features the two in rather creepy Gothic attire in a graveyard with Daria holding a skull, setting up a creepy story about a strange knock at the door. Though it becomes NightmareRetardant when Jane reveals that said knock at the door is a girl asking if the house's tenants would like a magazine subscription.
* Jake's [[EyeScream eye]] when blood vessels burst in "The Teachings of Don Jake". Especially when it happens to ''both eyes'' at the end of the episode.
* Jake's father. Although we never saw a complete appearance of this character, what we hear about him is quite disturbing (indeed, the only character in the entire series showing [[TheSociopath sociopathic traits]]). He is largely responsible for Jake's fragile state of mind and neurosis as the result of an abusive upbringing. Despite never appearing onscreen, his influence is felt every time Jake goes off on a tangent about his childhood. It's stated he was dead by the time he was Jake's age.
