Nightmare Fuel / The Mighty Thor

• Thor undergoing Sanity Slippage from being trapped inside his human alter-ego. He eventually goes so insane he ends up manifesting an extremely blood thirsty Imaginary Enemy warrioress known as the Valkyrie who constantly eggs him on to cave into his madness. Valkyrie constantly tries to assert herself and convince Thor to rise up against his father and never serve Asgard or Odin's will ever again, and kill his allies.
• Grey Gargoyle, despite being a goofy French Jerk, has shown how dark someone with Taken for Granite powers can be. At one point he assumed the identity of a famous sculptor by turning unwitting models into statues and selling them off later, becoming a Mad Artist. He even covered them in a see-through polish so they wouldn't change back after an hour. Iron Man catches on and exposes him, but even by then he's already wealthy enough at that point that he still escapes a rich man to carry on his schemes again.
• The entirety of Gorr the God Butcher's reign is one as deity-hunting Serial Killer, notably if you're a divine being. Thor explores the ruins of a pantheon's quarters after helping an alien world's residents and cannot help but reel in terror at the sheer prolonged brutality of the dead bodies of the alien world's gods. All of said gods are left in mangled pieces left around the place with looks of sheer terror on their faces as Thor recounts how slow their deaths likely were and how their corpses were left to rot for centuries.
  Thor: The face of a God. Frozen forever in fear and terror.
  • During Thor's first fight with Gorr, Thor recounts his childhood at being stuck in a room with a Mad God for five hours who went on a killing spree before being executed by Odin. Even millennia later, Thor cannot help but recount how traumatized he was being Alone with the Psycho who didn't lay a hand on him and simply and serenely explained how much the psychotic god enjoyed slaughtering children gods to Thor before being captured.
  • Thor recounts how despite his The Fog of Ages memories of friends, adventures, and lovers come and gone, one cave he must travel to will keep him traumatized his entire immortal life. Why? Because that cave is where Gorr captured Thor in his youth and tortured him for days. To get an idea of Gorr's skill with torture, he mentions the following before rendering Thor a screaming mess:
  Gorr: All Gods have their breaking points. It took me nine days to find [another immortal's]. And his flesh was made of stone. I am hopeful that you can keep me entertained for at least half as long.
• The supervillain Mr. Hyde has been strong enough to fight Thor, the Hulk, Spider-Man, and Captain America at various points in his career, and like the character he took direct inspiration from, he's utterly monstrous. In the Silver Age he disgusted Thor enough to declare him worse than Loki, he tried to blow up New York City with an oil tanker as revenge on his former partner the Cobra, and, in his most infamous act, brutally beat and tortured the Avengers' butler, Jarvis in the "Under Siege" storyline. Making things worse is that unlike the literary Dr. Jekyll, he doesn't have a good side. Calvin Zabo is just as bad as Hyde, and both sides of him retain a strong intellect as well as strength. He often switches forms to elude police or pursue heroes, catching them off-guard later as Hyde. Modern Age issues have had Zabo using the Hyde potion as a drug and either selling it on the streets or conducting experiments on others with it.
  • One of Hyde's creepiest appearances was in The Incredible Hulk #368, where he cornered Bruce Banner on a train, stabbed him, slammed him into a wall, and taunted him over their Jekyll and Hyde duality, explaining that he decided to kill the Hulk to prove he's superior, as there's no room for two Edward Hydes. Hyde eventually declares he's won, as while the Hulk cares for others, Hyde has no such weakness, and laughs as he falls off the train and down a cliff. The whole thing is made worse by the comic's use of shadows, giving the train scenes an eerie, nightmarish feel. Even Bruce admits that Hyde knew how to push his buttons.
  • In one Thunderbolts issue, Hyde and the rest of the team have to contain a prison break. While the Shocker subdues a tough-looking prisoner with his weapons, Hyde walks up and snaps his neck◊, scaring his own team.
• The Wrecker and his Wrecking Crew are really, really powerful thugs that have caused massive property damage in their battles. The Wrecker's enchanted crowbar can demolish just about anything, and he once brought an entire building down on top of Thor. The entire team has gone toe-to-toe with the Defenders, Thor, and the Hulk before, even knocking out the Hulk in one hit. They have good endurance as well, taking punches from Thor, the Hulk, Spider-Man, Spider-Woman, and Captain America without flinching. Their dangerous nature is lampshaded by Thor in Marvel Ultimate Alliance, especially when their first appearance is bragging about beating up a bunch of Asgardians and wanting to fight more gods.
  Thor: The Wrecking Crew is not to be taken lightly. They are humans who were mistakenly granted the powers of one of my people. More than once have they sorely tested my powers.
