* [[spoiler:[[VideoGame/SpiderMan Monster Ock]]]]. There's no way to defeat him: all you can do is run, and pray he won't catch you. Look up videos of him on youtube, and many of the comments will be similar to: "This scared me to death as a kid!"
** "DIE!"
** Similar to [[spoiler: Monster Ock]], there is Spider-Carnage. Imagine your favorite childhood character, turned into a horrible monstrosity that wants to kill everyone. *Shudders*
*** At one point, Carnage infected the SilverSurfer. The implications for the universe are horrifying.
* Marvel's ''{{Spider Man Noir}}'' is an ''{{Elseworlds}}''-esque comic retelling Peter Parker's story in a film noir setting. It's also chock full of disturbing stuff, including a scene of Fancy Dan being covered and consumed by a swarm of palm-sized spiders, Peter's nightmare sequence after being bit by one of the same spiders, a mutant, circus freak version of The Vulture with some [[ImAHumanitarian interesting dietary quirks]] that we get to see him indulge in [[spoiler:including tearing Ben Parker apart with his hands and teeth]], the reveal that this world's version of Norman Osborn [[spoiler:is called the Goblin because of his horribly deformed face, which he hides behind masks and makeup]], Kraven the Hunter [[spoiler:becoming a living host for the giant spiders]], the list goes on. The sequel is even more nightmarish, with the subtitle "Eyes Without a Face", the Sandman being an inhumanly strong thug who pops heads like bubble wrap and Dr. Otto Octavius conducting strange, forbidden experiments on "the lower races" to make them the perfect slaves. The ultimate fate of Robbie Robertson is that he's almost completely dead to the world and only responds to direct commands involving physical actions. He has a large indented scar on his forehead from the brain surgery performed on him.
** Anyone else seriously reminded of Dark Woods Circus after reading just that description? Kind of makes the mental images and such worse, doesn't it? If it didn't remind you of said song, you are officially welcome.
* Speaking of Spider-Man, the Tordenkakerlakk from the graphic novel ''Hooky'' is worth mention, due to the myriad of grotesque forms it takes throughout the book, for the sole purpose of ''stalking a little girl who has been alone for 200 years.''
* ''The Amazing Spider-Man'' story arc "Shed" is this. There's no return to Curt Connors for the Lizard. Not now. Not after what he does.
* Two books published by Marvel about the villain Carnage, ''Mind Bomb'' (which is by WarrenEllis by the way) and ''It's A Wonderful Life''. The character of Carnage is already up there to begin with, having been in prison serving ELEVEN consecutive life sentenced for murder before obtaining the symbiote, and after obtaining it, his only goals were to kill as many people as possible. The entire plot of ''[[MaximumCarnage Maximum Carnage]]'' was that Carnage wanted to kill everyone in Manhattan. He's a killer with no style or gimmick, who only wants to kill, preferably by brutal, gory means. But these books... both involve Carnage using the symbiote to connect to the minds of other people, which allows us to see what's in Carnage's mind. He lives in a world of corpses, willing victims, dark humor and frightening landscapes all of which house his knowledge, desires and memories of the past. There is even a special area where Carnage spends time hacking up Spider-Man copies for fun. One panel of ''Mind Bomb'' shows the "real world" as he calls it, which features a man eating intestines and holding a cup labeled "urine sample" as a drink glass, an elderly woman in bondage gear and a cop with a KKK hood shooting a man. In ''Mind Bomb'', the man he's connected to, Dr. Matthew Kurtz, goes completely insane from this experience. The second book plays more to Cletus Kasady's history as Dr. Kafka and John Jameson are connected this time, each mutating into a vicious creature (John turned back into the Man-Wolf, a previous villain form, and Dr. Kafka slowly changed into a cockroach) finally ending when a young black kid named Billy shows up deep within the area of repressed memories. Carnage threatens to kill him if they get too close but seems unable to (it's hinted that Billy was a childhood friend, but the details beyond this are never really said) and finally has a breakdown, releasing the two but left in a catatonic state. The artwork is graphic even for a Carnage story and the cover of ''Mind Bomb'' has him perched on a pile of human skulls. The oddest part? Both books were approved by the CCA. Even worse, ''IAWL'' seems to play with the idea that the people running the mental hospitals that house supervillains may actually be more evil than Carnage. ''Mind Bomb'' showed him as oddly intelligent for a supposedly uneducated guy but ''IAWL'' opens with Carnage ranting about the change in management. He even seems to be more than aware that many "accidents" that are resulting in patient deaths during their transfers are intentional and even calls out that the car crash that killed Wolverina (not Wolverine) was on purpose. This alone might be the most frightening aspect, Carnage himself calling out someone else for being worse than him and being right.
* During The Gauntlet, the Lizard kills his son. Not because he transformed with him close by; he hunted him down to prove he was The Lizard, and that Connors was dead.
* ComicBook/{{Venom}} himself was often this to Spidey, because of all the information he had about him, not to mention all the creepy commentary he would make and that constant big-toothed grin. Granted, he soon became more of an anti-hero, but he often went [[DisproportionateRetribution overboard when dealing out punishment to wrongdoers, which didn't exactly make him less scary.]]
** Venom's anti-hero status is some NightmareFuel for the Marvel Universe at large. Venom eats brains... and he's technically ''one of the good guys''.
* ComicBook/KravensLastHunt. Kraven the Hunter literally buries Peter alive and assumes the Spidey identity, only going extra rough on criminals while Peter's friends and family have no idea where he is for days. The What If? issue was even worse, with Peter actually having died and being eaten alive. Oh and every superhero is faced with persecution worse than usual, and we have no idea what happens to them (the narration says MJ's crusade on Superhuman rights makes her famous--it doesn't say she actually accomplished anything).
* In a story arc titled Venom: Shiver, set in the isolated Alaskan wilderness, an Army base loses contact with a nearby military research facility in the midst of a driving snowstorm. One of their officers, a young woman named Pat, takes a long and lonely journey through the storm to find out what's gone wrong. [[spoiler:What she finds is a dark, cold, silent facility filled with the mangled corpses of the staff, most covered not only with blood, but also a familiar-looking black sludge. Only a single, nearly catatonic survivor remains. She chooses to take the terrified man back to her base, followed by by a lone figure obscured by the snow.]] While the overarching plot of the story is, admittedly, pretty weak, and borrows very heavily from ''Film/TheThing1982'', what follows in the next several pages still manages to be a ''pretty'' unsettling look at what the Venom symbiote gets up to when it doesn't have a host like Eddie to moderate its violent impulses . . .
* There have been plenty of very dark stories over the years ("Kraven's Last Hunt", where Kraven the Hunter descends into madness, and drugs and buries Spidey alive, comes to mind immediately). Carnage and Venom also come to mind, with Venom being portrayed as a murderous stalker who knows Spider-Man's secret identity and is immune to Spider-Man's SpiderSense. A more recent example would be the story arc "Shed", where the Lizard destroys his human side, and goes on a horrible rampage.
* The Venom suit. An organism capable of sentient thought that relies on other organisms to live via a symbiotic bond. It affects you not unlike a drug, altering your state of mind and making you crave its power. While it provides benefits to you, it also uses your body against your will as it pleases and takes a toll on you in the long run. Once removed, some fragments of it retain inside the blood, as the rest retains not only the thoughts you shared, but all of your memories, that it will then share with its next host. It holds a grudge, will crave blood when it wants, and has an obsessive personality towards former hosts. Not to mention the powers it grants to its users, ranging from claws to tendrils.
* Norman Osborn and Gwen Stacy's [[http://i.newsarama.com/images/gwennorman.jpg sex scene]].
* Spider-Man can be pretty damn scary when he's angry. Take when he caught the Sin-Eater. Stan Carter has been going around killing people, including Spidey's friend in law enforcement Jean [=DeWolff=], so Spidey wants him bad. After saving first girlfriend Betty from being killed, Spidey disarms and smacks Carter around... but he just doesn't stop despite Carter's pleas. Every couple of panels cuts back to Betty witnessing this andlooking terrified. Spider-Man nearly beats a man without super-powers to death and probably would've if not for Daredevil stopping him.
* The Tarantula [[BodyHorror transforming into a giant, anatomically accurate tarantula]].
* A Spectacular Spider-Man (comic book) arc features Spidey and Black Cat stopping Ock from nuking New York. While the bomb is stopped Ock's tentacles bind Black Cat and one shoots her with a machine gun. That's disturbing enough but Spider-Man tears out several of Ock's extra arms and the issue ends with Ock on an operating table, refusing pain killers while his arms are reattached to him, vowing to return the pain to Spider-Man.

!![[Film/SpiderMan The 2002 film]]
* In the first movie, the birth of the Green Goblin. His costume to come is {{Narm}}, but when it's just Willem Dafoe strangling someone to death, then making a psychotic facial expression while giving a primal scream, it's ''terrifying''.
* Norman hallucinating that the Green Goblin is laughing and talking to him.
** The depiction of Norman's and Harry's SanitySlippage in general.
** The Green Goblin decides to interrupt a parade, whereby he kidnaps Mary Jane. Just before doing so? He ''vaporizes an entire balcony of people into ash with a single bomb. On-screen.''
* Green Goblin presenting Spider-Man with a SadisticChoice.
** Following that, there's the Goblin's beatdown on Spidey (though it turns from scary to ''awesome'' when Spidey gains HeroicResolve and then [[CurbStompBattle completely turns the tables on the Goblin]].)
* Peter is worried about Mary Jane and calls her house to make sure she's okay, but instead of Mary Jane, he gets the Green Goblin on the other line, who giggles and says in a creepy sing-song voice, "Can Spider-Man come out to play?"
* Then scene Spidey tries to save a woman from a burning building. He approaches her from behind, at which point she turns around, throws off the blanket she was wearing, and is revealed to be the Green Goblin, who plays the soundbyte of the woman screaming once more for surprise value.
