Mad Jim Jaspers

This villain lives a little bit under the radar. His monstrous power can twist reality and shift things as we know it. Even though this intensity seems admirable, let’s pause for a second. He’s a villain. He also has the word “Mad” in his name. This villain wants the world as a hellscape that’s straight from any nightmare. Furthermore, if the MCU saw this villain coming into play, all the other mad villains would probably be no match for his monstrosity (Quora).

Annihilus

Welcome to the Negative Zone, where Annihilius is the master and ruler of all things horrible. Just by entering this zone, you’ll feel an immense amount of terror. This is where this evil entity stands and hunger to conquer not just the MCU, but other universes as well, as many as he can get his hand on. Imagine if this evil being made his way down to earth. The world would be a different place. This marvel calls himself the living death that walks and will happily destroy any being that gets in his way of existence. He has agility, reflexes, and stamina like a superhuman (Comic Vine).

Arcade

We’re not talking about the games you played as a kid. We’re talking about Arcade, Marvel’s version of the Riddler. Don’t be fooled by his inconspicuous looks. Even though he looks non-threatening, he’s quite evil under that facade. He’s able to set traps for our favorite heroes and make sure they disappear for good. That’s not someone we want to see on the MCU. And with all of his aggression, his life mainly revolves around blood and getting as much of it as he can, with his calculated plans. He tricks people into thinking he’s a good guy by saying things like, “I promise… I’ve given up games of murder. I’m done with death traps. Okay… maybe a tiny little death trap.” Don’t fall into his death trap! (Marvel).

Mr. Smile

We’ve learned that villains with smiles are not ones to mess with. Their maniacal laugh and sinister smiles make us want to run very far away. This is all thanks to the Joker. But he’s not the only villain with a creepy smile. Marvel’s Mr. Smile is also a scoundrel who likes his creepy grin to try and lure people into believing he’s a good guy. He’s a demon in a skin suit. His teeth alone will instill terror in anyone who crosses his path. Besides, just look at those long, skinny, sharp teeth! We’re pretty sure everyone who saw this photo will have nightmares for the next week (Comic Vine).

Shuma-Gorath

This is one of those strange Marvel characters that no one has heard of, but he instills terror in anyone he crosses paths with. At first glance, you might think he’s just a regular guy who can’t instill that much harm in anyone. But this cosmic entity should not be reckoned with. He was one of the first rulers of Earth before anyone else came to claim his territory. According to the demon himself, “Before all was, I was. Before the time was, I waited. I fed on the screaming souls of the universes. I drank the spoiled milk of dead stars, I am the emptiness outside all understanding. And I am Shuma-Gorath.” Emptiness outside all understanding sounds downright horrifying. This man feasted on the ape-men until he was banished from the Earth realm. Even the MCU cannot handle his terror (Marvel).

Shadow King

The Shadow King is pretty much the Exorcist. It’s not something you want to casually cross paths with in the MCU. This malevolent entity is evil in every way possible. It travels from host to host and uses telepathy to gain its power through evil. This one belongs in a supernatural part of the world, where ghosts rule the night. This one believes that happiness doesn’t exist and that the true part of existence is to feel misery and be miserable. As Shadow King himself puts it, “Happiness is a lie. Life is horror. The light is always dying, all across the universe. The last star will flicker out someday. When it does, all that remains… shadow. And I will be its king.” (Comic Vine).

Carnage

Get ready MCU fans. Carnage is on its way and is horrifying. This sinister villain is no laughing matter. This demon looks like he’s straight out of Shadow King’s nightmares. In his own words, Carnage said, “Maybe if my host had a little more filial sentiment… a little more human love for his daddy… some of it would have crossed over to me. As it is, I feel nothing but cold empty contempt. I hate you, daddy.” Let’s take a look at some of his superpowers. He has superhuman strength, a regenerative healing power, genetic memory, and razor-sharp fangs and claws. To top it all off, he has spidery 360-degree senses, where every cell in his body is capable of acting as an eye, ear, nose, tastebud, or mouth (Reddit).

Mr. Sinister

This immortal geneticist plays with the lives of others. He manipulates to get what he wants. He destroys and causes terror, all for the sole sake of science. Mr. Sinister was inspired by the work of Charles Darwin, and his sole purpose on earth seems to be engineering humanity to create the perfect race of superhumans. He’s an immortal geneticist who plays with lives, and all because of him, demons tried to consume reality during the Inferno event. He views the world in a stone-cold way and doesn’t see the beauty, love, or light that many of us see. He’s emotionless and apathetic and prefers to ruin the lives of others than help them in any way, shape, or form (CBR).

Skinless Man

There’s a reason they say you need to feel comfortable in your skin. Skinless Man is one MCU Marvel character who needs to learn how to do just that. He likes to wear other people’s skin on his face. He used to have elastic skin, but after he had his skin peeled off his entire body as punishment, it was no use for him. He’s a skinless version of Mr. Fantastic. His elastic skin gave him the ability to stretch several meters away from his own body. Moreover, he could read text just by feeling dents on a page, and he could use his durable skin as a weapon. Furthermore, after his skin was removed, he taught his new skin how to expand and contract on a molecular level (Marvel).

Freak

The Armadillo Man, or Freak, is not a cute animal. On Earth, armadillos are considered adorable animals, but in the MCU, they’re the complete opposite. Freak is a drug addict who was chased down by Spider-Man. After Freak injects himself with animal stem cell fluids from Dr. Curt Connors’s lab, he develops a flesh cocoon chrysalis. He did this because he thought it was an illegal substance, though he got a wake-up call when he learned it wasn’t. He was then shot down by the police, where he formed another chrysalis. Not only did the substance make him skinless, he was horrifying to look at. He can bring himself back to life, making him capable of surviving any danger. Ultimately, in the MCU, he fits right in, but that doesn’t mean he’s nice to look at. For a Marvel villain, he’s comparable to all the other terrifying ones (Ultimate Marvel).

Reginald Fortean’s Abomination

This MCU villain might be too terrifying to show on screen. The story behind this guy includes Fortean, who took Gamma-Activated Tissue from the corpse of the original Abomination. Then, when he made contact with it, he was encased in an Abomination-like shell. He has an eight-fingered hand crown that sits on top of his head. Now, he has superhuman strength, enough to match the strength of the Hulk. Additionally, he can regenerate from grievous injuries like lost organs, has a claw on every single one of his fingers, and can generate a corrosive acid that can dissolve the flesh of the Hulk (Screen Rant).

Styk

As one of David Haller’s many personalities, Styx takes hold of the consciousness of anything and anyone he touches. Don’t get too close to this one. They become vulnerable and malleable in his hands. But that’s not what makes Styx so terrifying. The most horrifying thing about this one is that he can split himself from Haller and find a home in a corpse. Then, it turns its back on Haller and uses that corpse to try and control Haller to take over the world. He can rot and decay anything he touches, elongate his fingers long distances, and is immune to cancer (CMRO).
