G.I. Joe/Nightmare Fuel


 * There was an episode where the Joes had to stop an older woman who was using a machine to steal the faces of pretty girls to restore her lost youth. As if that wasn't creepy enough, after the Joes destroy the machine, the old woman covers her face with her hands and starts wailing "My Face! My Face!" We never find out exactly what happens to her face, and the final shot is a birds eye view of the Joes consoling the model for almost getting her face stolen while the woman is kneeling in the alone, sobbing, and covering her face.
 * There's also the scene in the Faked Rip Van Winkle episode "There's No Place Like Springfield", where Shipwreck's friends and family turn out to be Synthoids trying to pump him for information, and his neighbors start to melt in front of his eyes.
 * The appropriately named "Nightmare Assault". If the nightmares aren't enough, it averts Never Say "Die".
 * "Bazooka Saw a Sea Serpent" was another one. Giant robotic sea monster with flat-yellow glowing eyes that eats ships and turns their mass into more girth, so it keeps getting larger. The appearance was scary enough, but then you see that the humans eaten by the monster get turned into slaves that are worked so hard that they collapse in a dead sleep in the brief moments that ever-vigilant shock-prod tentacles let them have a "coffee break". And then an attempt to stop the thing fails and it turns from a Cobra-controlled monster into an uncontrolled monster, some laser-eyed Godzilla serpent that wants to eat EVERYTHING, just a blind malicious hunger in the shape of a giant robotic snake. By the way, did you know that a little boy can memorize how long it takes to fast-forward past an episode of G.I. Joe on a multi-episode VHS tape so he doesn't have to ever look at the screen?
