!!The original novel:
* Clopin running through the crowd in the final battle scene with a HUGE SCYTHE, hacking at the horses and guards until he is surrounded by severed limbs. [[spoiler: He dies shortly afterwards.]]

!!The Disney film:
[[caption-width-right:320:'''"And He shall smite the wicked and plunge them into the fiery pit!!!'''"]]
* The gargoyle that randomly comes to life just to finish off Frollo.
* The statues of the saints looking down at Frollo, and of the Virgin Mother's eyes opening as the lightning flashes in the prologue.
** Frollo looked positively ''demonic'' during the chase leading up to that scene, and it definitely didn't help that the guy ''killed'' Quasimodo's poor mother. And what's worse is that he thought he was guiltless!
* Quasimodo tied to a spinning platform as the crowd [[ProducePelting throws eggs and vegetables at him]] is ''terrifying''. Fortunately, Esmeralda's intervention cuts the scene short.
* Judge Claude Frollo himself.
** Most of the other Creator/{{Disney}} villains were terrifying and evil in their own right, but Frollo trumps a majority of them due to being very, very normal and realistic. It gets better. The chances of you personally getting attacked by [[Disney/TheLittleMermaid a sea witch]], [[Disney/{{Aladdin}} a sorcerer]], or [[Disney/SnowWhiteAndTheSevenDwarfs an evil queen]] is slim to none. Are there genocidal racists out there who use religion to justify their beliefs, and convince other people to follow them? Oh, yes.
** His obsession with Esmeralda is quite [[NoYay creepy]] indeed, and not at all subtle.
** The scene where he confronts Esmeralda while she's about to be burned telling her to "Choose me or your pyre".
** The VillainSong, "Hellfire". ''[[CrowningMusicOfAwesome Fabulous]]'' [[IncrediblyLongNote singer]], [[ArsonMurderAndAdmiration though.]]
*** When he says "Let her taste the fires of hell," you can actually hear the faint screaming of a woman being burned alive! Chills.
** Frollo looks very like [[Franchise/{{Batman}} The Joker]] when he grins, and his cold glare is equally as frightening.
* Imagine for a moment you are one of the soldiers under Frollo's command. Specifically, one of those attacking the Cathedral. You've stuck by the Judge through all of his monstrosities. The city is in revolt, the Cathedral is throwing beams, stone and molten lead at you. All of this is explainable. Then the birds attack and everything is put into perspective. The Cathedral isn't attacking you. God is and now the Devil has a claim on your soul. Pious or not, that would be terrifying.
* The [[{{HSQ}} last twenty-five seconds]] of [[http://www.youtube.com/watch?v=7CVwYC7WrP0 "Paris Burning"]] is the embodiment of fear and terror itself. In the film, it's played over a clip looking over the skyline of Paris, glowing bright red from all the fire and the smoke filling the sky, as though Frollo really has brought Hellfire to Earth.
** The chorus of "Kyrie Eleison" (meaning "Lord, have mercy") make both nightmarish and heartbreaking as well.
* If you interpret the gargoyles strictly as part of Quasi's imagination, not to mention how he behaves around Frollo, it really puts into perspective how much psychological damage has been done to this poor boy in his 20 years in isolation.
* Clopin giving a SlasherSmile when he was about to execute Quasimodo and Phoebus as spies. Thankfully Esmeralda stopped him before it was too late.
* The burning of the miller's house just because he and his family were supposedly hiding gypsies. Said family included at least one child and a ''baby.''
