The villainous ecosystem of the Marvel Universe is full of bad guys who could conquer or destroy the Earth. However, even among this deadly number, there are some who are more dangerous than others. These ten Marvel villains are the greatest threats to the Earth, bad guys who are the best of the worst.
10) Kang the Conqueror

Kang the Conqueror is one of the Avengers’ greatest villains, and is way more dangerous than most fans realize. Kang conquered the future and decided to go back in time and take out the most formidable warriors in history. He’s a master strategist and combatant, armed with the greatest weapons of the future. He’s traveled to alternate universes and defeated their greatest defenders, figuring out way to destroy everyone who would stand against him. He’s conquered the world before and he can do it again, with only the might of Earth’s heroes able to stop him.
9) The Sentinels

The Sentinels are mutant-hunting robots created by Bolivar Trask to go after the mutant race. They are armed to the teeth with technology that allows them to adapt to or inhibit the powers of most superhumans, mutant or not. They seem like the type of robotic cannon fodder villains that heroes waste all the time, but the classic “Days of Future Past” showed how truly dangerous they are. This story took place in a future where the robots were able to slaughter most superhumans on the planet and take over. Since then, we’ve gotten numerous futures where the Sentinels have conquered the world, showing just how dangerous the march of progress can be.
8) Doctor Doom

Doctor Doom is one of the greatest villains in comics. He’s one of the most intelligent men on the planet, a master of magic who has been Sorcerer Supreme, and the monarch of Latveria. He’s tasted godhood several times over the years, conquering the multiverse as God Emperor Doom in Secret Wars, and most recently the emperor of the world in One World Under Doom. Doom wouldn’t destroy the planet (well, more than likely; you never know what kind of deals he’ll make for power), but him potentially taking over the world is always in the cards.
7) The Beyonders

The Beyonders are some of the most powerful beings ever encountered in the Marvel Multiverse. They come from outside of the multiverse, and have godlike power on a level that makes objects like the Cosmic Cube and the Infinity Stones look quaint. They’ve succeeded in destroying just every Earth in the multiverse with the Incursions, and even the most powerful beings in the existence can’t defeat them in a battle of power vs. power. The only way to beat them is to somehow outsmart them, like Doom has in the past, because fighting them is a losing proposition.
6) The Infinity Stones

The Infinity Stones (they were called the Infinity Gems before the MCU and it was a much better name) aren’t sentient lifeforms, but that makes them even more of a threat. The six Stones — Power, Mind, Reality, Time, Space, and Soul — give beings complete control over those elements. When brought together, they make their bearer into capital G God. The Stones aren’t bad on their own, but the fact that anyone who can find them can use them for anything they can imagine makes them a massive threat, as shown in the ’90s Marvel classic Infinity Gauntlet (and Avengers: Infinity War and Avengers: Endgame for the greater population who don’t read comics, although they were super-nerfed).
