Cletus Kasady, aka Carnage: I've been thinking, with you superhero types always up in my business, I don't really have the time to savor each and every death the way I'd like. I was a little miffed at first, but then I realized... go big or go home! So instead of picking people off one by one until someone stops me, I'm just gonna harvest as many as I can and then squeeze the life outta 'em all at once! It's like an arcade game. Sure, you're gonna game over eventually, but you gotta aim for the high score, y'know? (...) Aww, what's wrong, spider? Aren't you gonna crack some jokes? Fine, I guess I'll tell the jokes. [Grabs a baby] Why'd the baby cross the road?
Spider-Man: You touch a single hair on that kid's hair and I swear to God I'll-!
Carnage: What? [Turns hand into axe] Don't you wanna hear the punchline? (...) To prove it had guts!

  • One More Day fanfic Breaking the Deal: Mephisto, having manipulated Peter Parker and Mary Jane Watson into sacrificing their marriage in order to save Aunt May's life, uses it to kickstart his plans for multiversal domination.

When he makes his move on the Earth, he unleashes his demonic minions on New York City, where they waste no time in killing civilians while he has Mary Jane whisked away to his lair, where he keeps her as a slave bound by barbed ropes. Not just one for merely deceiving others into making deals that will ruin their lives and those of others, Mephisto actively revels in his manipulative behavior, fondly reminiscing about tricking Ghost Rider into making a deal that would kill his father figure, and gleefully crushing Mary Jane's spirit with the knowledge of what their disastrous bargain led to.
  • Polarity:
    • The extradimensional conqueror Dormammu is one of the two beings responsible for the zombie outbreak, and the ultimate Big Bad of the story. In his latest bid to conquer the Marvel Universe, Dormammu has his lieutenant Grim Reaper sacrifice his former servant The Hood in order to unleash a zombie plague from another universe, causing the deaths of billions of men, women, and children alike, all of whom are cursed with a state of undeath that turns them into feral monsters fueled by a never-ending, painful hunger for flesh. Devastating most of the world, Dormammu has Grim Reaper launch an attack against a SHIELD refugee camp housing the survivors of the New York City zombie attack, seeking to use the survivors' life energy to manifest on the physical plane. When Shocker wipes out all of the zombies and Grim Reaper is forced to summon Dormammu using their less-potent Death Energy, an enraged, weakened Dormammu disowns Reaper for his failure and has Electro shock him to death before attempting to kill everyone at the SHIELD site himself. As arrogant and cruel as always, Dormammu is every bit the monster that he is in canon.
    • Eric Williams, aka the Grim Reaper, is a smug sociopath and Dormammu's number two. Having sold out humanity to The Dread One to slake his lust for power, Grim Reaper helps his master usher in the zombie plague, and shares culpability in the death and undeath of billions. Enforcing his master's will on Earth, Grim Reaper seeks to eliminate those who would pose a threat to his plans by ordering Electro and the Vulture to murder the Shocker, and forcing a zombified Hulk to kill a bus full of people in order to lure out and slaughter the Avengers. All the while, Grim Reaper tries to tempt people to his side with promises of power and pleasure beyond their wildest dreams, and viciously tortures those who blow him off, such as the Punisher, who he has crucified and left to slowly bleed to death, and the Shocker, whom he allows Electro to brutalize to his heart's content. At the climax, Grim Reaper leads hordes of the undead in an attack on SHIELD's Central Park refugee camp in the hopes of slaughtering everybody inside and using them as sacrifices to summon Dormammu onto the Earth.
