History NightmareFuel / AmericanDad

* How about Santa Claus? Do you think he's a jolly fat man who loves giving toys? No. Not at all. He's a man who can hold a grudge for a long time as seen when Steve accidentally kills him and then comes back to life to kill the Smith family with an army of elves, reindeer, and snowman monsters! "Minstrel Krampus" also shows how evil he is when it's revealed that Krampus punished kids because he cared for them, while Santa spoils them rotten no matter who was naughty or nice because he makes money off of it.

** The episode itself became darker as Francine discovered that the woman who was found murdered in the parking lot in ''broad daylight'' was Anne Flemming, a former member. Just as Francine thought she was safe at home, to her horror she recognized burns on Stan's shirts and her seasonings disorganized. A phone call right after confirmed that The Lady Bugs were able to get to her friends, family, and [[AndYourLittleDogToo her seasonings]] and even ''rigged her vacuum cleaner to explode upon turning on'', which sends Roger flying.

* Stan's eating disorder in "The American Dad After School Special". When we finally see how skinny he ''really'' is... it isn't pretty. The episode is pretty clever about it, too. At first, you think Hayley and Francine are trying to sabotage Stan's attempts to lose weight to get back at him for judging Steve's girlfriend, but it's later revealed that they're trying to help Stan since he's starving himself to death.

** The fact that the "hunt" was a literal game intended to welcome guests to the island, and that she died and was effectively eaten for ''nothing''. Francine decides it would be best to LetUsNeverSpeakOfThisAgain, and for good reason.

*** It gets even worse when we see both Hayley and Steve succumb to the temptation and put their family into the goo themselves so that THEY can have some quiet time away from them, proving they're just as terrible as Stan in the end

*** Oh, and did we mention simply touching the goo the unavoidable side-effect of making you STERILE?!

** It then becomes Nightmare Fuel for Stan when he learns that the sleeper agent program was a failure because eventually, the brainwashed subjects will turn on their handlers. Too bad Stan happens to be Hayley's handler.

* While the actual reason why Stan doesn't want to enter a bike race with Steve is a lot better, the story he tells about his friend getting hit by a train and having pieces of the bike lodged into his organs seems a little... unnecessary.

* "Moon Over Isla Island": the dictator Juanito tripping over the upwards escalator after choking a corn dog, which in addition to killing him, leaves his body disfigured.

* Stan, Francine, and Jesus getting [[BuriedAlive buried alive]] by [[TheAntichrist the Antichrist]] in "Rapture's Delight". They're only trapped for a few seconds, but the fact that Francine's scream gets drowned out to silence as they're buried is rather chilling. And it happens so quickly as well.

** The unlicensed vet ''replaced his testicles with his eyeballs''. If a MercyKill has ever been demanded by Man and God in the history of the world, this was it (Steve tearfully begs the dog to die)! Fortunately, Stan complies after realizing his mistake... ''by blowing Kisses up with dynamite''!

** The shot of Hayley's butchered face is the episode's Creator/{{Hulu}} thumbnail, so people who aren't aware of that scene when they click on the season 13 tab are in for one hell of a surprise.

* "Beyond The Alcove Or: How I Learned To Stop Worrying And Love Klaus". Klaus manages to hypnotise almost everyone in Langley Falls into loving him, using hypnosis a la ''Film/GetOut''. Only Roger and Parker Deay manage to resist this. Even Francine, who had resented Klaus throughout the episode, wasn't immune to it thanks to Klaus's use of an air horn to hypnotise her, which he almost immediately proceeds to do. And then, after a two-month TimeSkip, Francine and Roger return to the town to see Klaus has turned it into a full-blown {{Egopolis}} with faded colours, loudspeakers broadcasting his voice, statues of him and pictures of his face everywhere. And anyone who doesn't voice their love for Klaus is captured in a similar manner to ''Film/InvasionOfTheBodySnatchers''. Thank goodness Francine was able to use a series of {{Chekhovs Gun}}s to return everything to normal.
