There are some pretty evil villains in the Marvel Cinematic Universe.

This list will focus onvillains who are far more evil in the comic books than their MCU counterparts.

Across the many Marvel Comics timelines, Quentin Beck has done some pretty messed-up things.

During this event, Loki killed Thor’s grandfather and caused all manner of havoc.

The MCU’s Loki is a trickster, butthe comics' version is an outright psychopath.

In the pages of Marvel Comics, Stane has been evil from a very young age.

Stane has a terrible moral compass, which fits his alter-ego, the criminal Iron Monger.

But killing a dog just to win a chess match?

Horrifyingly, this dastardly villain turned all of Washington to dust, leading to thousands of innocent people dying.

This act alone depictshow little Kang truly cares about human life.

Ultron might be stoic and devoid of morals, but that only makes him more dangerous.

Not to mention,the Baron comes from a family of the worst villains of all time: Nazis.

But there was never a chance that Marvel Studios could fully adapt the character from the books.

Many consider himfar worse than the average Nazi, which should be more than enough for most.

Even in the modern age, the man is trying to commit World War II-esque acts.

However, one of the things that makes him so compelling is the motives behind his actions.

Thanos truly only wants what’s best for the universe, albeit in a twisted way.

This is not the case with comic book Thanos.

The thought of all the terrible things Thanos has done in the books is bone-chilling.

He murders billions to impress Death; somehow, the different intentions make his actions feel so much worse.

Thanos has also courted women from multiple planets over the years, birthing many children.

He also murdered both of his parents and fully dissected his mom.

The thought of all the terrible things Thanos has done in the books is bone-chilling.

However, this action is absolutely nothing compared to the horrors the Green Goblin has brought in the comics.
