History NightmareFuel / TeenTitans

** What's worse?, they have all of the memories, thoughts, and emotions, so they know about their losses, insecurities, and tics that make them sloppy in combat.

*** A small bonus nightmare, the kids laughing at Beastboy in the freak show? If you think you recognise their designs, you do. They're Mutants, as in Frank Miller's 'The Dark Knight Returns', the future timeline where Batman retired and let Gotham to completely to shit as a street-gang called 'the Mutants' took control

** The ending of "Haunted" is the creepiest part of the entire series. The dust on Slade's mask didn't activate on it's own. Somebody activated it with a remote. ''Outside the tower.'' We never find out what triggered the mask.

* Any episode with Slade or Trigon. Slade is particular, since he's basically the Titan's archenemy that uses a nasty combination of brains and brawn to browbeat each of the Titans into submission and takes [[SoftSpokenSadist great pleasure in trying to break and torment them in the most intimate ways.]] The amount of emotional abuse he's inflicted over the series is staggering, nearly driving [[TheHero Robin]] insane with paranoia and caused [[BreakTheCutie Beast Boy and Raven]] to have near complete mental breakdowns. Considering he's an adult preying and mentally tormenting teenagers, the whole situation is profoundly creepy. Trigon is notably WORSE, since he's the setting's equivalent of the Devil, causes Slade to fear him, and causes the apocalypse just by entering the world. Even better, season 4 has ''both'' of them.

** "That was ''nothing'' compared to what I'm going to do to you."

* Any episode with Slade or Trigon. Even better, season 4 has ''both'' of them.

** All of the interactions that Slade has with Raven in "Birthmark" are seriously creepy.

* Kitten's boyfriend Fang has a ''giant spider'' for a head!
* Melvin's imaginary teddy bear in "Hide and Seek". Think about it: it's a giant, super-strong, invisible-when-it-wants-to-be teddy bear with rows of pointy teeth and razor-sharp claws.
* And there's [[PeoplePuppets the Puppet King]], who is ''completely creepy.''
** His death was even creepier. He loses the connection to his magic, and without his magic, he's just... a puppet. He just drops mid-sentence and returns to being an inanimate ventriloquist dummy.
* Kardiac, a giant mechanical heart (with tentacles) that abducts small children for unexplained reasons. [[YouDoNotWantToKnow Which is probably for the best]].

** Interestingly, Slade almost gets creepier in Season 4. While he still talks like the emotionless ManipulativeBastard he was in the first two seasons, his movements when in combat seem much more primal and at times mimic some downright zombie-esque moves due to being undead. It's downright jarring to compare exactly what he has become to what he was before.

** Even more unsettling is when Cyborg manages to pull aside Fixit's cloak... we see a truly ''bizarre'' show of biology: nothing but pulsating/beating organs a la [[StarWars General Grievous]]... no blood/bones or anything remotely like nerves or muscles, and a ''deformed third arm'' randomly jutting out. How Fixit ended up like this, no one knows.

* Starfire going through alien puberty in "Transformation" and the scene in the same episode where she meets the lady who looks like the benevolent DC character White Witch - but who turns out to be a [[OneWingedAngel bug-like creature]] who ''eats young Tamaranians going through said Chrysalis type alien puberty''(The scene where she transforms from her fake persona to her true form is also extremely frightening). Just imagine it. You're being enclosed a chrysalis for reasons you don't understand and nobody can explain, nobody is there to help you, and just as the cocoon closes, ''you're going to be eaten by an alien''.

* Since both Slade and Raven tend to inspire this, there's ''that'' scene in "Birthmark" where Slade is sent by Raven's demonic father for no other reason than to torture her about her destiny to cause TheEndOfTheWorldAsWeKnowIt? Which he does by shredding her clothes and then tossing her unconscious body off a roof? "Oh... and happy birthday."

* Mother Mae-Eye. It's actually a pretty creepy episode, what with zombie cookiemen, the menacing, hopeless music, what could actually be in the pies (They're red, [[HumanResources think about it]]), and there's the Mean Green Mother herself, who is difficult to explain, but scary none the less, think [[Literature/TheWonderfulWizardOfOz Wicked Witch of the West]], then give her MindControl.
* Madame Rouge is actually in-show nightmare fuel considering Titans and members of the H.I.V.E. Five alike are shown to be absolutely terrified of her, for good reason since she is a murderous shapeshifting rubber woman who is effectively indestructible. Exceptionally displayed in "Trust" where she relentlessly hunts down Honorary Titan Hot Spot no matter where he goes or what he throws at her, chasing him and beating him down until he exhausts himself like an unstoppable predator hunting their prey. Not to mention she can actually shapeshift to effectively drive her victims crazy by perfectly pretending to be figures they trust before revealing herself to strike. In "Calling All Titans", Robin freezes her, then shatters her into little frozen pieces. She then reforms herself in a manner similar to [[Film/Terminator2JudgmentDay the T-1000]]. She also managed to wear down Kid Flash when the entire Hive Five couldn't even touch him.

* Kardiac, a giant mechanical heart (with tentacles) that abducts small children for unexplained reasons.

--> '''Slade:''' I am the thing that keeps you up at night, the evil that haunts every dark corner of your mind. I will never rest, ''and neither will you''.
** Even creepier is the fact that the above quote is said in a very similar tone to Batman's "I am vengeance! I am the night! I am Batman!" meaning that that was probably where Robin's subconscious got the idea from, meaning that he literally considers Slade to be Batman's counterpart.

** "That's ''nothing'' compared to what I'm going to do to you."

* Terra and Raven's mud fight. Sure, it sounds kinky in text, but poor Raven... The episode really drives home the Geelong of betrayal through the dialogue, where Terra's cold taunts push Raven far enough that she goes into demon mode, and ''even that'' doesn't help her in the fight. She's then helplessly [[PrimalFear drowned]] in mud by her former friend, onscreen, the first time one of the Titans in the show actually looked like they were about to be successfully killed off. None of the other fights in that episode are as prolonged or vicious.

** Raven, despite reaching her [[EleventhHourSuperpower White]] [[SuperMode Raven]] form permanently as a result of her increased strength and presumably [[ScrewDestiny stopping the prophecy of "the jewel of Trigon"]] [[TheArchmage alone]], has suffered from major trust issues with the loss of her friends, and [[GoMadFromTheIsolation isolated herself from the world]] so that [[BrokenBird she doesn't have to be hurt anymore]], though Cyborg still knows where she is due to her transmitter in her cloak. Apparently her friends really were what she needed to keep from complete and total isolation from humanity, as is implied later in [[HowWeGotHere "Go!"]] and the season 4 [[CosmicHorrorStory Trigon arc]].

* The episode "[[WhatDoTheyFearEpisode Fear Itself]]". The scariness kicks in when you remember that Raven was the one who made these things without even thinking about it. Yes, the snarky, demonic, demigoddess who's in near constant control of her emotions. Makes you wonder about the extent of her powers.
** One particularly unsettling part was the part where Cyborg goes next. Immediately after Starfire's taken by those creatures, Cyborg pulls Raven outside and convinces her to keep moving. After a while, she agrees, and starts walking, while Cyborg just stands there, illuminating the hallway with his shoulder-mounted flashlight. We get a shot of Cyborg looking ''very'' put out over Raven's poorly timed aloofness, but still looking in her direction. We pan over to Raven, and the light turns off. She turns around, and he's ''gone''.

** The [[EldritchAbomination monster]] from that episode is pretty creepy too. A green wraith-looking thing covered in black fanged mouths and tentacles.
** Don't forget the blood-curdling scream that the woman in the movie makes. That same scream later wakes Raven up, but it's [[TheDisembodied disembodied]].
* "The Sum Of His Parts" is quite terrifying. Here's Cyborg, a guy who's had most of his body replaced with robotic parts, and a fellow cyborg named Fixit has kidnapped him with the intent to ''finish the job''. It's a total horror movie premise made even more frightening by the fact that it's not part of the seasonal arc and [[MoodWhiplash starts out as]] one of the more light-hearted filler episodes. On top of everything, Cyborg's worst fear is losing his humanity and when he begs for release on those grounds, Fixit calls his humanity "flawed". Plus, there's something chilling about that mask Fixit tries to replace Cyborg's face with (And at the climactic moment, he presses it on, muffling Cyborg's speech so that no one can hear his screams).

-->'''Slade''': If you join me... if you swear to serve me... if you never speak to your friends again... I will allow them to live. But... if you disobey even the smallest request... I will annihilate them, Robin - and ''i'll make you watch.'' So, do we have a deal?

* How about that EldritchAbomination that Raven becomes when she gets angry? Big black tentacles, her eyes all red, she gets really tall. And then there's that thing she turned into to scare Gizmo into helping them. [[ShadowDiscretionShot We don't actually see it]], but apparently there were tentacles, horns, and dragon-like ''jaws''.
