History NightmareFuel / Smallville

* Brainiac. Just about everything about him is NightmareFuel. The cold personality, the ruthless manipulation of everyone around him, the {{Squick}}-enducing ability to MindProbe victims by thrusting liquid metal fingers into their eyes (also his preferred method of killing), the matter of fact way he talks about eradicating life, how he morphs to and from a black puddle...he's this trope personified. [[ArsonMurderAndJaywalking Oh, he also enjoys]] using his [[EyeBeams heat vision]] to [[PyroManiac burn stuff up]] ForTheEvulz.

* ''Fracture'': To put it simply, like {{Batman}}, LexLuthor's mind [[WesternAnimation/JusticeLeague is not a nice place to be.]]

** [[EvilerThanThou And he actually plays]] TheCorrupter on LexLuthor, who is trying to pull a HeelFaceTurn. AndThatsTerrible.

** [[MoreEvilThanThou And he actually plays]] TheCorrupter on LexLuthor, who is trying to pull a HeelFaceTurn. AndThatsTerrible.

* '''Bizarro'''. Unlike in the comics or in the {{DCAU}}, where Bizarro is usually only confused and stupid rather than actually evil (he actually pulled a HeroicSacrifice in SupermanTheAnimatedSeries), in ''Smallville'', he could give {{Brainiac}} a run for his money, if not worse because this Bizarro radiates malicious joy of destruction and is dangerously intelligent. He first gorily assaulted MartianManhunter as mentioned before, and repeats his signature style on humans. When in his child host, he is the EnfantTerrible of the highest degree. You really want to skip the part when the child wakes up.

* ''Nemesis'': A [[EldritchAbnomination phantom]] killing two people.

* ''Freak'': [[spoiler:LexLuthor has his people abduct Chloe to his secret lab then experiment on and painfully humiliate her. Chloe figures out she is the next in line to be killed and orders Clark to burn a hole in her shoulder to remove the tracking device. Her screams of pain would make anyone's blood run cold. At the end of the episode, Lex watches a video of Chloe stripped naked and strapped to the experiment table. As she struggles, he delivers this line with a hint of Psychotic Smirk:]]

* ''Labyrinth'': When [[EvilDetectingDog Shelby]] starts barking, Clark goes to investigate. Suddenly, he is ambushed by something and wakes up in a mental institute. Everything changed, Lex has amputation because Clark failed to save him, Martha is married to Lionel, etc. Chloe appears to be the only one who knows what is happening. Then there is a painful mental tug-of-war as Lana and Chloe tries to convince him that she is telling the truth. Chloe is then shot in the chest by officers, adamantly stating that she is as sane as he is, twitches a few times and [[DiedInYourArmsTonight dies in his arms.]] Throughout most of the episode there is no real music... just an extremely ominous hum. [[spoiler:It is an illusion by a phantom. The cracks in the fake reality begins to show as every name he finds - on books, noticeboards, etc. are people he knows]].

* ''Static'': The freak of the week rips all the bones from his victims. Bone marrow all over the place. [[spoiler:[[UpToEleven Eating a guy alive.]]]]

* ''Subterranean'': The Freak Of The Week is pretty damned horrifying by himself, being a farmer keeping immigrants as slave labour and using his powers to drag any would escapees into the ground to suffocate. But Clark takes him down, problem solved. Cut to the guy on an operating table and Lex instructing a doctor to "put him with the others." Lex then strides out with total calm as truely spine chilling music plays, walking past cage after cage as hands desperately, pleadingly reach out at him. The door closes behind him with the fatal legend "33.1" enblazoned upon it. If there was any doubt which team Lex is now playing for [[MoralEventHorizon they are now gone.]]

* ''Zod'': The Phantom Zone. [[IDontLikeTheSoundOfThatPlace It is called the Phantom Zone for a reason.]]

* ''Mercy'': Some hacker appears in a scary metallic mask and plays hangman with Lionel's life, then trap him in his office and gives off the sense of being everywhere. Then he starts a series of DeathTraps...
