Most Marvel Comics fans recognize villains like Doctor Doom, Thanos, Kang the Conqueror, and Apocalypse. These are the most dangerous villains, the ones the MCU can build an entire phase around. There are plenty of villains in the Marvel Universe that don't quite hit that A-List mark, but are incredibly dangerous nonetheless, placing them above villains that are purely played for laughs.

B-List villains can show a bit more personality. Perhaps their goals aren't as ambitious, and perhaps their designs are strange, forcing some heroes to underestimate them. Whatever the case, B-List villains like Mister Sinister, Mysterio, and MODOK display strange powers during their usually extravagant, creative villainous plots.

10 Mysterio's Illusions Are Dangerous But His Costume Is Ridiculous

Marvel Comics' Mysterio with the Superior Six in Superior Spider-Man

Mysterio is a villain who's both defined and held back by his classic Silver Age costume. Mysterio is easily one of Spider-Man's dorkiest villains. He wears a giant fishbowl on his head, yet the look is so iconic that every iteration of his costume without it feels like it's missing something.

Given his inclination for the stage, Quentin Beck should have been able to come up with a better costume, but perhaps that's the reason why his movie career failed. Still, he remains a dangerous threat. Mysterio even hopped between universes to challenge both Peter Parker and Miles Morales in the Spider-Men miniseries.

9 Mister Sinister's Wacky Personality Doesn't Make Him Any Less Dangerous

Mister Sinister from Krakoa-era X-Men in Marvel Comics

An earlier version of Mister Sinister was more akin to a Saturday morning cartoon villain. But during the 2010s, writers like Kieron Gillen gave Sinister a personality makeover. These days, he's a mad scientist and a comically overacting ham.

He's cloned himself and altered his own DNA so many times that his behavior is unpredictable. He's gained a love for the flair and dramatics that come with being a villain, but he's also incapable of empathy and has zero morals. Sinister is more protective of his cape than his teammates. Though he's working with Krakoa now, he constantly betrays his allies while achieving his own goals.

8 Living Laser Is A Small-Minded Crook Composed Entirely Of Light

The Living Laser glows in Marvel Comics

Arthur Parks was a scientist before he turned himself into pure light for the sake of winning his ex-girlfriend, Lucy Barton, back. He failed, but he managed to become one of Iron Man's biggest foes. While Stark has surpassed most Silver Age villains, Living Laser's power allows him to keep up with Stark no matter how many Iron Man suits he builds.

As a being composed entirely of light, he's a walking oddity. As a scientist, he could have made billions simply studying his own nature. Instead, he was consumed by revenge and conquest. Its this small-minded attitude that results in his continuous losses.

7 Grey Gargoyle Is A French Chemist Who Turns People To Stone

Grey Gargoyle lounges in Marvel Comics

Paul Duval was a chemist who turned himself into a metahuman during one of his experiments. Afterwards, he learned he could turn anything he touched into stone, including other people and himself. But while other people turn into statues, Grey Gargoyle remains completely functional. With his new powers, Gargoyle chose to become a notorious thief in France.

From an era where villains didn't need much motivation, Gargoyle bounced between wanting immortality and wanting desperately for people to take him seriously. Despite his lethal powers, he was too strange and dangerous to join Norman Osborn's Dark Avengers.

6 Super-Adaptoid Copies The Powers And Outfits Of Every Avenger

Super Adaptoid battles the Avengers in Marvel's Silver Age

Amazo was a popular character from the Justice League cartoons who could copy the heroes' abilities. The Avengers actually have their own version of a powerful android that can copy the powers of any member of the team.

The Super-Adaptoid's abilities make it a challenge for any combination of Avengers, no matter how strong they are. Strangely, the Super-Adaptoid doesn't just mimic powers, but appearances as well. While the visuals helped readers know which powers the Super-Adaptoid copied, the design would often look ridiculous. Super-Adaptoid looks stranger and stranger the more characters it mimics.

5 Molecule Man's Sheer Power Affects His Mind

Molecule Man produces energy in Marvel Comics

As the Molecule Man, Owen Reece is one of the most powerful beings in the Marvel Universe. He possesses control over matter at the molecular level, manipulating it as he sees fit. While he's been unable to manipulate organic matter in the past, this has been indicated to be more of a mental block than an actual weakness.

Working alongside Doctor Doom, Owen took out all the other Molecule Men in the multiverse to gain infinite power. Molecule Man is one of the few villains to hinder his own abilities. His mental blocks were originally used to keep his dangerous powers at bay. The more blocks he overcomes, the more power he wields.

4 Fin Fang Foom Is A Shapeshifting Alien That Chooses To Live As A Dragon

Fin Fang Foom soars in Marvel Comics

Fin Fang Foom is one of Iron Man's most powerful villains. He isn't talked about often because he simply doesn't "fit" into the rogues gallery of any enemy he fights. He's a shapeshifter from an alien planet, but he often takes the form of a massive dragon.

Because of his incredibly destructive powers, Foom has been worshiped by a number of human cultures in the past. He's a character that doesn't match Iron Man's usual themes at all, as Tony normally faces tech-based villains. Foom's alien physiology and mystical nature actually make him the perfect Iron Man villain. Fin Fang Foom is not a villain that can be easily stopped with technology, forcing Tony to think outside the box.

3 MODOK Is The Head Of A.I.M. And A Literal Floating Head

MODOK uses his brilliant evil mind in Marvel Comics

MODOK is the ultimate weapon of A.I.M., right down to his name: the Mental Organism Designed Only for Killing. MODOK eventually became one of the major heads of the A.I.M. organization, taking over the group entirely. If A.I.M., evil engineers who work in fringe science, wasn't weird enough, MODOK made them even weirder.

The character is a giant head trapped in a floating chair who shoots death ray beams from a gem in his head. Nothing about him makes sense, and yet he's featured in hundreds of comics. He's even become the star of his own television series and MODOK is full of Easter Eggs for fans to find.

2 Korvac Is A Cosmic Being With A Human Mind

Michael Korvac wields cosmic power in Marvel Comics

Korvac was one of the Avengers' deadliest threats. Formerly a human, Michael Korvac attained godlike power and attempted to use it to reclaim his former lover. The Avengers battled him to a standstill, but it cost the lives of multiple team members including the Wasp.

Ashamed by the destruction he'd caused, Korvac resurrected the fallen Avengers before disappearing. Korvac is misunderstood, but his powers are too unstable. Korvac may possess godlike powers of the cosmos, but he is still just a human being. The Avengers often use his humanity to their advantage. Korvac is normally overwhelmed by his powers, as any human being would be.

1 The Owl Takes Special Drugs To Give Him The Powers Of An Owl

The Owl strategizes in Daredevil comics

The Owl is one of Daredevil's oldest and most powerful foes, debuting in Daredevil #3 by Stan Lee and Joe Orlando. Leland Owlsley commands a massive gang and is as much responsible for the damage to New York City as the Kingpin. Having a crime family wasn't enough for Owlsley.

He discovered a special drug that granted him superpowers with frequent doses. He gains super strength, enhanced speed, and can even grow talons. Peter Parker gains the powers of a spider, and suddenly, everyone wants to emulate their favorite animal. Owlsley could easily delegate the dirty work to his henchmen, but after gaining the powers of an owl, he's more than a match for Daredevil in the ring.
