Hercules (1997 film)/Nightmare Fuel

Disney film

 * The Fates share an eye between them. One. Single. Eye.
 * The Titans are so scary, they almost look like they were coming out of the screen.
 * DEAR GOSH, the Titans. They were heartless killers, and it was implied in the opening song that the remains of their victims WERE LITERALLY EVERYWHERE.
 * The Hydra: it's monstrous, no pun intended, and what makes it scarier is that it's like the one monster that gave Hercules trouble - even more than the titans, it was the only thing that came close to killing him.
 * Not to mention with the cel-shaded CGI, it looks more realistic while blended with the traditional animation. Granted, it was more impressive in 1997, but even now it's still disturbing.
 * That scream.
 * Meg is seen dying in agony and then shown clearly as dead as Disney can get away with on a G rating.
 * Hercules' rescue of her soul showing his rapid aging gives both kids and adults nightmares.
 * As if these two aforementioned examples weren't enough, the Fates attempting to cut both threads of life with scissors is enough to make viewers young and old cringe and hold their breaths in fright of what would happen.
