Please don't list this on a work's page as a trope. Examples can go on the work's YMMV tab.
Nightmare Fuel: Gorillaz
There's plenty of it, but the Cyborg is basically a nightmare fuel manufacturing plant. Her creepy, frigid demeanor, combined with the lovely incident where we see her without her face, make her wholly terrifying.
The Evangelist *shudder*
Some of the videos border on this.
The last fifty or so seconds of "Rock the House" aren't particularly pleasant, either. Squick.
Try listening to the first part of "M1A1" when driving alone late at night and without feeling a little bit frightened. "Hello? Is anyone there?" repeated as you travel down the dark, desolate road echoes the movie that sound bite is from...
The inside◊ of Cyborg Noodle. It's even scarier in her ident for Plastic Beach.
Seeing Robo!Noodle all hooked up by wires in Plastic Beach was unnerving as well, but it's less unnerving than the art on the CD sleeve depicting her in the same situation... hunched over with a dark grin.
The entire video for Clint Eastwood is spooky, what with the zombie gorillas and Del the rapping ghost, but the creepiest part for this troper is right at the beginning when Murdoc gives a really evil sounding laugh and fading to a close up of his face wearing a sinister expression.
Also in Plastic Beach, for your enjoyment, Sarcasmo.
The way 2D turns around in "Feel Good Inc.", jerkily twisting his body around until his head is on completely backwards before he finally turns it too.
The black body-bag looking thing in the lobby that moves when you click it. What's in there, anyway? Anyone brave enough to click it enough times to find out?
The "Superfast Jellyfish" video is terrifying. The jellyfish are way too happy for things that have just been microwaved and are in the process of being eaten. Their movements are pure Uncanny Valley as well; somehow the flopping is reminiscent of hanging victims.
Several moments in the "On Melancholy Hill" video fall under this Robo!Noodle puking up a (still alive) octopus frightens even those in canon (namely 2D) and, while the manatee-napping bit is more of a Tear Jerker than anything else, the way that Boogieman is sort of... massaging the poor thing can definitely give you the jibblies.
The fact that this is a world in which Murdoc Niccals not only has yet to be safely locked away from society, but was in fact forced to care for a coma patient, was allowed to keep joint custody of a small child, and is now "legally entitled to experiment on monkeys" should be Nightmare Fuel enough.
Murdoc drugging 2D during his radio show was exceptionally horrifying.
His general treatment of 2D, especially during Phase 3.
Not to mention the bit when Murdoc is screaming about "the fog."
Sweet Jesus, "Fire Coming Out of a Monkey's Head." The freakishly emotionless Vincent Price-esque narration. The ominously droning background music. The twisted storybook-style music video/animation (*shudder* Strangefolk...). And the crown jewel on all this, the GODDAMN ENDING LYRICS.
"And then came a sound. Distant at first, it grew into castrophany so immense it could be heard far away in space. There were no screams. There was no time. The mountain called Monkey had spoken. There was only fire. And then...nothing."
Though probably Played for Laughs, 2D screaming "HE'S KEEPING ME PRISONER!" during Pirate Radio 4 (found on the Gorillaz website) is actually fairly unsettling once you look past the hamminess of it. He just sounded really, really desperate.
2-D's black eyes. One who begins to listen/watch the Gorillaz may wonder why they look like that, and soon shudder at the reason for it- although despite his creepy appearance, in terms of personality he's harmless and kind of adorable in his own, stupid way. Murdoc, on the other hand...
There's the upbeat, prideful tone of Superfast Jellyfish... Which also happens to be about disasterous overfishing and polluting the sea until nothing's left alive.
Overload, overload, overload, comin' up to the overload...
"Feel Good Inc." is a rich, stylish song with a vivid nonconformist message, but its video creeps into Fridge Horror territory the more you think about it. How long have the people been trapped in the tower? Apparently long enough to facilitate military helicopters circling the building so no one will escape. And then there's 2D's helpless, troubled demeanor, which falls somewhere between eerie and heartbreaking.Not to mentionMurdoc's persistent gyrating.
On the subject of that song, the laughter in the background occasionally sounds Laughing Mad. -shudders-
