History NightmareFuel / LostInSpace

* The whole concept of the BadFuture, and how every misstep of the journey led to it: first the Robot destroying their navigation, using the hyperdrive, them exploring the Proteus, them getting stranded on the planet, Dr. Smith succumbing to his spider-bite and then murdering the women. The result is that Will spends decades in the ramshackle remains of the Jupiter II trying to build a time-machine so that he that he can stop it from happening, while all the while Spider-Smith was just planning to use it to return to Earth just so that he could rule it and eat all the inhabitants. All because Will's dad never came back after searching for a replacement power source. And the way it is discovered plays out like the characters have crossed over into a DarkFic of the franchise's central premise as a whole: just Dr. Smith, Will and the Robot in the ruins after everyone else is dead, and the Doctor is still manipulating Will to do his bidding and it's all been for not.

* When Robot is programmed to kill the Robinson Family and John shoots at him. The Robot dodges the shot, then turns slowly back to face John, as if it's ''glaring'' before saying its next line in such a cold tone.

** The ManEatingPlant that attempts to devour [[AdultFear Penny]].

* In the two-parter episode "The Keeper", the titular "Keeper" is an extremely frightening man. He has a cold and detached attitude about him. All while looking down upon the Robinsons as lower lifeforms. When he contacts his superior, he openly expresses the idea of [[AdultFear kidnapping]] Penny and Will for his interplanetary zoo. It's rather creepy how neither the Keeper nor his superior have any qualms about taking the children whatsoever.

* While not shown, the fact that trade fair mentioned in "The Space Trader" has a market for [[SlaveryIsASpecialKindOfEvil slave trading.
