Although fans of the Marvel universe dream about what it would be like to live in that world, they don't consider how dangerous the MCU actually is. It would be pretty awesome so be able to have superpowers, but at what cost?

Plenty of the Marvel planets are extremely dangerous and have been known to decimate worlds, entire universe's, and kill some of our beloved Marvel heroes. With so much at stake, having a superpower might not be so worth it after all. Or if it is, these are the ten planets to be overly cautious when inhabiting them.

10 Klyntar

Symbiote Planet Klyntar

Klyntar is a marvel planet inhabited by symbiotes which is the driving force that harnesses the addictive and controlling matter that powers Venom. This planet is a rapidly growing and destructive force that infects entire planets when able to leave Klyntar.

Several heroes have tried to stop this planet from rapid progression, but fail due to the ever-growing effects of the symbiotes.

9 Korbin

This planet is home to the race of Korbinites which was one of the first planets to prompt superheroes and supervillains alike. Due to the mass population of highly advanced technology and mutations forming new-found heroes and villains, it became a target for the MCU and was attacked on various occasions.

Due to the destructive and haphazard nature of the world, it is chaotic and henceforth known as much too dangerous for inhabitable life.

8 Sakaar

Sakaar, known as the green planet that holds intergalactic gladiator matches, is highly dangerous because it was resurrected by an infinity stone. The Hulk has been seen in comics going to this planet and struggling to survive in the gladiator games because there are more foes than just the one they face in the arena.

The world fights back due to the infinity stone magic it holds, so on or off the battlefield, inhabitants aren't safe.

7 Hala

The race of the Kree inhabit this planet which poses a huge problem because they are destructive, scientifically advanced, and extremely powerful. Upon expanding their technological advancement, it got much too out of control and the once peaceful planet became too powerful for its own good.

Due to the long-standing war between the Skrull Empire and their own shifting ideas of good and evil, this planet is a problem for the MCU.

6 Battleworld

Doctor Doom is a popular villain who is known to reshape and revitalize this planet. It is prone to destruction and is constantly being destroyed, but keeps getting rebuilt from fragments of other existing planets making it a danger to itself and a danger to neighboring planets.

Due to supervillains and heroes continually fighting to either keep the planet alive or destroy it, it's a breeding ground for chaos.

5 Xandar

Xandar Guardians of the Galaxy

Xandar is famous for being a major target of villains and evil worlds alike. Xandar is home to the Nova Corps who are a major target for intergalactic villains which is only part of the problem. Xandar is a major hub open to alien visitations and welcomes beings from all over the galaxy.

This makes the world very untrustworthy and opens the realm to those to attack it.

4 Asgard

Asgard is home to the beloved Marvel hero and God Thor. However, because it is known to produce great heroes such as Thor, it makes the world a target for villains. Asgard is constantly under attack and although a breeding ground for heroes, is considered extremely unsafe.

Young heroes train on this world and unfortunately have been known to get attacked quite frequently.

3 Titan

Titan is home of the mad God Thanos. It is also the training ground for Moondragon. With such powerful forces stemming from this planet, it is constantly being attacked by its own inhabitants. But that was, for the most part, before it was destroyed.

As seen in Avengers, Thanos explains that Titan was once a beautifully sound and structured planet, but was brutally destroyed and decimated.

2 Earth

Our home planet is the second most dangerous on the list because it is home to most of the Marvel heroes. This on the flip side makes it extremely dangerous at the same time because the Marvel heroes are constantly being attacked and using Earth as their battleground.

Along with the wonderful heroes and personalities that come with the MCU, Earth also produces villains that constantly rise up and gain power. Unfortunately, our own world can't be trusted here.

1 Ego The Living Planet

Ego The Living Planet

Ego, as seen in Guardians of the Galaxy 2is the horrible creation of Ego the God who also happens to be Starlord's father. The planet is living and is controlled by this villainous mastermind of a God. The power that he holds is much more powerful than that seen in any other world due to the fact that he has control of the entire planet.

Things are constantly being created and destroyed and not even villains can stop the mass production of this planet.
