[[folder: Regular Epsiodes ]]
* Ed's NightmareSequence at the beginning of "Rock-A-Bye Ed".
** After Mom!Jonny [[WipeThatSmileOffYourFace tears Ed's mouth off]] and sends him down into the "Kanker pit", Ed ''tears open a new mouth to scream!''
* Some scenes from [[BizarroEpisode "1+1=Ed"]].
** Jimmy [[BodyHorror melting]].
* Edd going insane from not taking a shower in "Cleanliness Is Next to Ed-ness".
-->'''Edd:''' May I use ''your'' shower? ''(makes a rotten smile)''
* The insect hunting scene in "Nagged To Ed", especially when Ed gets stuck on the giant spider web...
-->'''Ed:''' Help me guys! I don't want the fluids drained from my body!
** The scene where it looks like three monsters [[spoiler: (they're really the Kanker sisters)]] are after them and the Eds scream and the picture's colors invert.
* "The Eds are Coming" is ''definitely'' DarkerAndEdgier.
** The scene with Edd in Ed's room. It's the show's only attempt at NothingIsScarier.
** [[GainaxEnding The ending]]. Oh my goodness, [[GainaxEnding the ending]].
* A scene from "Urban Ed" where Jimmy is making is way around the cardboard people in the Eds' mock city, all while hearing the "people" laugh at him. It's an oddly dark scene in an otherwise lighthearted episode.
** Becomes AdultFear once you realize kids in real life can go through that situation if they're not careful.
* Sarah herself is pretty scary especially when she's pissed. Even though she looks like a normal innocent little girl, she's really a walking talking nightmare who's not afraid to kill a person out of anger.
* Eddy [[GoMadFromTheIsolation going crazy]] in "Laugh Ed Laugh" is surprisingly creepy.
* Ed going [[UnstoppableRage absolutely berserk]] in "Little Ed Blue", it's essentially a person acting like a wild animal while still mentally and physically human.
** Sarah was afraid of him, to put things into perspective.
* The end of "Take Your Ed and Shove It." Even worse, it was supposed to be the last episode.
* "The Day The Ed Stood Still" has Ed wearing a monster suit and became one with it, not just act, but '''become''' the monster.
* Ed's [[BodyHorror allergic reaction to rabbits]].
* When the Eds get trapped in a haunted house in "Honor Thy Ed" and fall into a GambitRoulette set up by [[spoiler:the Kanker sisters]], culminating in the Eds [[spoiler:being forced to marry them.]]
** The whole "tunnel of love" scene is pretty disturbing. Especially since the Eds are [[spoiler:mysteriously stripped naked]] halfway through it.
* Double D appearing as a "mole-mutant" in "Boom Boom Out Goes The Ed", especially when you consider how Rolf and Kevin managed to get out of the sewers unscathed.
** When Ed lights up his head with a flashlight, instead of a skull, we see a toast with holes for eye-sockets and melted butter smushed into the center. Now consider that [[FridgeHorror Ed's favorite food is buttered toast]]...
* Ed's story in "Once Upon An Ed" where the Kanker Sisters eat radioactive mashed potatoes and turn into gigantic monstrous versions of themselves and chase the Eds; especially the part where they combine their faces and make this UncannyValley looking face. Even Eddy pointed out how surreal Ed's story was becoming.
-->'''Eddy''': [[NoFourthWall Ed, your story's]] [[LampshadeHanging getting weird!]]
* The a.k.a. Cartoon logo that appears at the end of every episode. Probably one of the reasons why kids never watched the full end credits.
** For those who don't know about this, it's basically a picture of a guy getting impaled by a pencil.
*** Even worse is the version on the HalloweenEpisode, where the screen is splattered with blood. [[FridgeHorror Since the guy is being impaled by the pencil...]]OhCrap!!!
* The scene in "Out with the Old, in with the Ed," in which the Kankers send the Eds to their new "homeroom." While May and Marie give their usual flood of kisses to Ed and Edd, who are too afraid/weak to fight back, what happens to Eddy before he gets his usual act is...really unnerving.
-->'''Eddy:''' Ok, THAT'S IT! I'm telling the teacher on you (Lee dressed as a teacher)! *Raises hand*
-->'''Lee:''' *Bends down to Eddy's face* I'm all ears, ''my little teacher's pet!'' *Laughs and pushes him into the stall for kissing*
* There's something...unsettling about the scene in "Brother Can You Spare an Ed," where Ed is looking back and forth between the Jawbreakers he wants and the fudge Sarah asked him to get for her and Jimmy. Every time Ed looks at the Fudge you can hear what sounds like jeering laughter, and Ed looks like he's about to have a mental breakdown and even starts physically shaking... Just what was going through the poor guy's head?
* The Kanker sisters in general, which also counts as an In-universe example for every other character on the show. Despite being PlayedForLaughs, most of their antics are quite disturbing since most scenes involving them have them torture and/or [[BlackComedyRape rape]] the other kids, especially the Eds, in unsettling and odd ways. Whenever they show up, it won't end well for them.
** "We know where you live!"
** "A Twist of Ed" showed that they have no problem invading the Eds' houses. Lee even makes her move on Eddy while he was taking a shower (thankfully, he still had his [=PJs=] on.)
* The ending of "Tight End Ed". The fact that Eddy is kidnapped by the rival team makes the ending freaky.
