10 Most Powerful Cosmic Superheroes from Marvel Comics, Ranked

The Marvel Comic-Book Universe is vast and mysterious. Naturally, there are villains and superheroes just as powerful. For decades now, we have witnessed big battles between good and evil, apocalyptic scenarios, end of humanity and just when everything looks hopeless, good guys will pull victory from the jaws of defeat. Hailing from the farthest and weirdest corners of the Universe, the cosmic villains of Marvel Comics are challenged by their cosmic counterparts – the space-based superheroes.

So it stands to reason (for the nerd in us) to make a list of the most powerful of Cosmic superheroes. Presenting 10 Most Powerful Cosmic Heroes from Marvel Comics – Ranked from weakest to strongest…..


Groot hails from Plant X. Apart from the fact that Groot belongs to this planet, nothing else is known of his home world. Groot is apparently Planet X royalty. He is known for the phrase ‘I am Groot’ but his limited vocabulary doesn’t change the fact that Groot is actually incredibly intelligent. He is also one of the strongest beings in the Marvel universe, can resurrect from the dead and is amazingly durable. But no way he can fight the likes of Thanos or Black Order.

Adam Warlock

Adam Warlock is the result of an experiment conducted by the Enclave to create the perfect specimen. Warlock is a mysterious superhero who has a range of abilities. He was considered powerful enough to be granted the guardianship of the Infinity Stones. He is also incredibly hard to kill. So much so that it could be considered one of his superpowers. James Gunn, the writer-director of GOTG movies wanted to tease Adam Warlock in post-credits but the studio did not allow him. He had this to say about the entire episode:

“I had to fight for Adam in the post-credits sequence. Because I really thought that’s where that should go. And I thought one of the main reasons to have the Sovereign in the movie was to give audiences the hint that Adam Warlock is coming. That was one of the reasons for them to exist. And I wrote that post-credits sequence in the first draft of the script. And then there were a lot of questions about whether or not we should put that in there, because people were going to expect Adam Warlock in Infinity War. So one of the things I promised, which I do all of the time on Twitter, is letting everyone know that Adam Warlock is not going to be in Avengers 3 or 4. It’s just not going to happen. Because I didn’t want people to have false expectations of what they thought was going to happen with Adam.”

He has now admitted that Warlock won’t be part of MCU near future and fans have to wait. He tweeted this:

“I awoke with a vision of the Stakar Ravagers scene in my head and couldn’t stop thinking about it for days. We almost didn’t include the Adam Warlock scene because he was definitely not in Avengers 3 or 4 and we had no plans for him in general. Despite so many people thinking Adam will show up in Vol 3 that is something that we have never confirmed. Who knows how long it will take him to bake in that cocoon. That said, I love Adam. But the time must be right.”


Monica Rambeau was once Captain Marvel. She then obtained a different set of abilities and is now better known as Spectrum. Spectrum’s energy form is nigh invincible. She can fly at light speed, survive unaided in space and her already staggering intellect is further enhanced by the way her energy form helps her process data, giving her a form of cosmic awareness.

Captain Marvel

Captain Marvel’s real name is Carol Danvers, a Kree/Human hybrid, and a former USAF pilot. Carol can fly, is insanely durable and has the power of energy projection and super strength. Carol is also incredibly formidable in her binary form and the fact that she can amplify her powers by absorbing nearby ambient energy. She is among very few superheroes who can beat Wonder Woman in a death battle as she can use her lasso against her, also she can exploit Wonder Woman’s weakness for piercing weapons.

The famous actress Brie Larson has been chosen by Marvel to portray this iconic female superhero. According to Marvel head Kevin Feige, she is the most powerful of them all. She will be first introduced in her solo movie and then she will be brought into Avengers 4 where she will fight against Thanos and his forces alongside remaining Avengers and Guardians.

Black Bolt

Black Bolt is not just a superhero but the King of an entire race of enhanced superhumans called the Inhumans. Black Bolt was exposed to the mutagenic Terrigen mists while still in the womb, giving him a voice whose mere whisper can level mountains. Black Bolt also has limited energy manipulation powers. He also has enhanced physical Inhuman attributes and is trained in Inhuman Martial arts by Karnak.


Quasar’s powers originate from the Quantum Bands, a gift from the cosmic entity known as Eon. The Quantum Bands allow Quasar to perform several incredible feats like flying at more than light speed, generate powerful planet destroying energy beams and creating a planetary energy shield that can even detect a micrometeorite passing through.


Richard Rider was made a member of the Nova Corps, an intergalactic peacekeeping police force based off Xandar. Richard Rider played a prominent part in the Annihilation event and helped stop the tear between Cancerverse and the Marvel Universe. His speed and energy absorption abilities are only rivaled by another cosmic superhero, the Silver Surfer.

Beta Ray Bill

A cybernetically enhanced protector of the Korbinite race, Beta Ray Bill literally gave Thor a run for his money when he lifted Mjolnir and proved himself worthy. Odin then gifts Bill a hammer similar to Mjolnir, called the Stormbreaker that grants him mystical abilities. Add to that his cybernetic enhancements; Beta Ray Bill is not only immortal but also invincible.


Gladiator’s abilities are unique. He has the powers of super strength, speed, flying unaided in space, fire breath, resistance to telepathic attacks and a host of other abilities. Gladiator’s greatest power though is his faith in him. The more he believes he can win, the better his chances are at victory. The guy has been at the forefront of the Shi’ar Empire and its conquests since centuries, maybe even more. He also is a bit of a Superman Rip-Off.

Silver Surfer

The Silver Surfer is a being of pure Cosmic Energy. As a former herald of Galactus and enhanced by the very Power Cosmic, the Silver Surfer was once considered to be the greatest threat to the universe lest he turns evil. He is too much of a noble soul to turn into a villain. The Surfer’s board is the fastest mode of transportation in Space. His skin is also indestructible and able to take a direct punch from the Hulk itself.

Silver Surfer

He is part of the Fantastic Four stable of characters whose rights are not owned by Marvel, but by 20th Century Fox. Although, Disney is in the process of buying Fox in a historic multi-billion dollar deal but nothing is confirmed as of now. Stan Lee, the veteran writer of Marvel comics expressed his wish to relaunch him. He said: “He’s the one I want to see more. He’s the most philosophical of all the characters I’ve ever worked on. And I have an idea for my cameo in that one!”

Captain Universe

Captain Universe is a mantle that has been passed down from one random individual to another. The Uni-Power possesses a host during a time of great need and grants them nigh godlike abilities. The Uni-Power is the highest a sentient being can achieve without becoming a God. The Uni-Power has since been weakened since the universe fractured. After the Secret Wars event, the Uni-Power hasn’t even been mentioned yet and is most likely lost. Its last known host was Tamara Devoux.
