YMMV / Marvel Comics Presents

• Complete Monster: The first volume has several exceptionally vile villains.
  • "Elements of Terror" storyline (feat. Man-Thing):
    • General Selbert is the corrupt head of Project Glamor. In an attempt to duplicate the Super Soldier Serum, or "The Juice", Selbert runs every corrupt dealing he can, financing misery and death all over to reap profits and craft Project Glamor, where a supposed Satanic cult kidnaps victims to be used as fodder for nightmarish experiments that see their flesh warped and the victims in unbelievable agony before they succumb to death. Frustrated with a lack of progress, Selbert has Dr. Railsback made into an experiment himself before attempting to murder any who might expose the program.
    • Dr. Laurence Railsback, the chief scientist of Project Glamor, is the man in charge of carrying out all its atrocities. Having abductees brought to him, Railsback injects them with his serum to deform their bodies, leaving them in horrendous agony before expiring. With no remorse, Railsback just continues moving on to the next victims until Selbert has him "replaced", prompting the mutated Railsback to go on a brutal spree to murder the general.
  • "Fellow Travelers" storyline (feat. Ghost Rider): Tsin Hark is a vile Chinese sorcerer seeking to scourge the Earth of science to return the world to an age of tradition and dark magic. Tsin Hark systematically murders countless hundreds of innocent Chinese immigrants, storing their blood in huge iron drums he stores by the stack. When tempted by an outer power to forsake his humanity for more power, Tsin Hark gleefully does so, and his tainted blood destroys him when it mixes with all the innocent blood he's gathered as an expression of his sheer evil.
  • Issue #157's "Jury of Your Peers": Number 16 is an especially sadistic Hydra member who captures dozens of S.H.I.E.L.D. agents and horrifically tortures every single one of them for answers to questions he hasn't asked. Nick Fury assumes it's to attain information, but Number 16 admits it's only because he wants to hear them scream.
• Harsher in Hindsight: In issue 4 of the 2019 volume, Spider-Man runs into C-Rank supervillain Gibbon, leading to the webhead to laugh in amusement at the fact that he's missing Star Wars to tangle with a villain like him. After the events of Hunted which we see Gibbon's sad backstory just before he's unceremoniously killed off with the web-slinger cradling his dying body had quite a few people crying "Too soon!"
