Nightmare Fuel / Bakemonogatari

Just Ougi Oshino being Ougi Oshino.

In General

• Ougi Oshino is a very bizarre character at best, and very creepy at worst, with the palest skin in the series, so pale, that it looks supernatural, which freakily mix with the black hair. Not helped by the wide, pitch black eyes, long sleeves that cover her hands for the most part, as well as maintaing a smile at most times.
  • That's not even mentioning their relationship with others, particulary Araragi.

• A few of the openings can be pretty unsettling, mainly due to the surreal visuals and subtle uses of Foreshadowing.
  • The alternate fifth opening theme "Sugar Sweet Nightmare" is a bit unnerving. One scene in particular is when human hands burst out of the mouths of cats and roughly grope Tsubasa's naked body as she tries to run away from them.

First Season

• In Kizumonogatari II, when Araragi is being cornered by Episode during their fight, Hanekawa suddenly appears and tells him the weakness of the vampire hunter's mist technique. What Episode does to this? He attacks her with his cross and causes Hanekawa a wound so severe she ends with her guts spilling out of her body (in all its glory, without any kind of censoring like in the aforementioned fight of Araragi against Kanbaru). Fortunately for Hanekawa, she is healed before something worse could happen.
  • Araragi's Roaring Rampage of Revenge against Episode for this is not better either. In his wrath, he beats Episode so savagely that, if Meme wouldn't had appeared, he would had probably ended not only killing his oponent, but also losing his humanity.
• In the opening to Kizumonogatari Part 1: Tekketsu-hen, we are treated to a gorgeously animated scene of Araragi spontaneously bursting into flames after being exposed to the sun, due to him just recently becoming a vampire. The combination of the fluid animation, muted color palette, and Araragi's guttural screams of pure anguish as he's being cooked alive make this scene all the more frightening.
• In Kizumonogatari: Reiketsu-hen, we have this lovely scene of Araragi, excited to return to Kiss Shot for his celebratory farewell party with her after their sweet bonding moment just a few moments ago, walking in on her feasting on Guillotine Cutter's now dead body (guts and all). What makes this scene worse is how casual Kiss Shot was being with Araragi even as she shows him Guillotine Cutter's half eaten head by the hair in front of him, with Guillotine Cutter's head and body being rendered in complete CG to show just how unnatural the scene was. Araragi throwing up afterwards is an understandable response to the whole thing.
  • Just minutes later, in the throes of a Despair Event Horizon, Araragi briefly fantasizes about Hanekawa. Said fantasy ends with him kissing her, and then accidentally ripping her face off with his teeth.
• See No-Holds-Barred Beatdown on the main page; Suruga's constant hysterical screaming of "HATE HATE HATE HATE HATE HATE!!!" while savagely beating Koyomi is quite disturbing. Good thing it was censored...
• Senjogahara can be a little frightening with her threats...
• The way the snake decides to attack Koyomi.
• There's also one of the final scenes in the last episode. The cat licks Koyomi's neck and his tongue is sharp enough to cause Koyomi to spout blood out of his neck.
• Near the end of Tsukihi Phoenix, we find out that Tsukihi, Koyomi's younger sister, has been possessed by the apparition of a Dying Bird ever since she was in her mother's womb, giving her immortality and never truly being human. And how is this revealed, you may ask? By having Kagenui command Yotsugi to suddenly destroy half of her body right there in front of Koyomi.
  • Araragi's rage here somehow manages to be worse than his rage in Kizu against Episode, because unlike his rage moment before, there's no tranquil fury before he fully goes mad with rage. Instead, he turns into a wild animal in human form, nearly grabbing hold of Yotsugi. Thank God Kagenui stops him from trying to gruesomly murder Yotusgi.
• You thought Kanbaru's beatdown on Araragi was bad? The one he receives at the hands of Kagenui in the climax of Nisemonogatari is as terrifying as that one. Araragi is beaten so brutally he ends severely deformed (like if he was a zombie) and with a hole in his rib cage. See the results yourself to look how bad it is.◊

Second Season

• From Mayoi Jiangshi:
  • It's partially due to the series' Anachronic Order, but Ougi's first and sudden appearance without fanfare comes off as unsettling. It's even creepier since Koyomi is strangely open with her.
  • The realization that Hachikuji's death and subsequent Lost Cow are the only things that kept the world from ending in the main timeline. That is a lot of pressure on one person, even if they didn't know it.
  • Kisshot's appearance at the end. She doesn't do anything particularly horrible onscreen, but her reaction upon seeing them...
• The ending of the Nadeko Medusa arc has the newly-awakened Snake God Nadeko stabbing Koyomi, whose body is already torn up from her previous assault, and giggling creepily in a shower of his blood. The entire arc is her descent into insanity.

Final Season

• Everything in Sodachi Oikura's arc is possibly one of the most unsettling parts in the series. For starters:
  • Unlike before, there are no apparations involved. This makes everything regarding Sodachi's past startling more realistic and horrifying.
  • The truth of Sodachi's mother's disappearance. Due to her mental issues, she was unable to admit to the fact her mother starved to death and thus spent two years caring for her corpse. Only once it decomposed beyond any recognition did she register her mother as "gone". Brrr.
  • There's no happy end for Sodachi. Unlike all other stories, here we're just reviewing the past. Everything has already happened and there's no denying it. Sodachi herself even lampshades this further.
• The ending of Koyomimonogatari consists of Gaen calmly walking toward Araragi while talking about how to stop the darkness that engulfs the city... Before casually pulling the Kokorowatari and slashing Araragi into literal pieces that scatter into the air. And take note that this is a rare occasion where the series defy exaggeration from Unreliable Narrator because the narrator himself is in shambles now. This is what's actually happening onscreen.
• No love for Ougi's appearance in Zoku? Basically, take the creepiness of Ougi before, and ramp it up to 11 with multiple Nightmare Faces. Some of the scariest ones include this close-up, this one, and especially this one.◊
