10. CAPTAIN MARVEL
Debuting in 1968’s Marvel Super-Heroes #13, Carol Danvers was once a member of the United States Air Force, accompanying the Kree hero Mar-Vell, the original Captain Marvel, on several adventures, before an explosive accident merged Carol’s human genes with Mar-Vell’s Kree genes. This essentially made Carol a Kree-human hybrid, resulting in the birth of one of Marvel’s mightiest cosmic heroes.
The character is amongst the strongest members of the hidden group of superpowered beings known as the Eternals, an ancient race of genetically-altered humans created by the Celestials, and alongside his teammates shields humanity from the blight of the vicious Deviants, though Gilgamesh has a particular penchant for protecting the people of Earth. Joining the Avengers in a time where their membership was at an all-time low.
Another member of the extremely powerful Eternals, Sersi easily ranks as one of the group’s most overpowered members, and remains one of the most underrated characters in the Marvel Universe in terms of ability. Introduced in The Eternals #3, Sersi is tens of thousands of years old, coming into contact with Thor several times over the millennia. She officially joins Earth’s Mightiest Heroes in Avengers #314.
A character with several incarnations across the Multiverse, the origin of Hyperion depends heavily on the Universe he hails from, but they’re all ridiculously powerful nonetheless. Designed to be similar in nature to Superman, the Hyperion most closely associated with the Avengers hails from a recently destroyed Universe, with his memories being stored nonlinearly as light -- meaning he experiences the death of his home world constantly.
6. SCARLET WITCH
Earning her reputation as one of the most dangerous entities in the known Marvel Universe, Wanda Maximoff, better known as Scarlet Witch, has had something of a tumultuous career since her introduction in 1964’s The X-Men #4. The daughter of Magneto and sister of Quicksilver, Scarlet Witch was initially recruited into the nefarious Brotherhood of Evil Mutants by her father, going up against the X-Men on several occasions.
5. DOCTOR STRANGE
Quickly becoming a master of the mystic arts under the tutelage of the Ancient One, Doctor Strange eventually becomes the Sorcerer Supreme following the death of his mentor. As the Universe’s foremost expert on mysticism, Doctor Strange, assisted by the trusty Book of Vishanti, is able to perform countless powerful spells that can affect the fabric of reality itself.
4. BLUE MARVEL
Given his status as one of the most profoundly powerful heroes in the entire Marvel Multiverse, it’s strange that more people haven’t heard of Adam Brashear, better known as Blue Marvel. Turning Conner into the bitter villain Anti-Man, the accident also transformed Adam into Blue Marvel -- one of the most powerful heroes the world has ever seen. Once Adam’s identity as an African-American was revealed however, the hero was forced into retirement due to the racism of the era.
Considered by many to be amongst the most powerful entities in the Universe, Robert Reynolds, aka the Sentry, is one of Marvel’s most complicated, and often frustrating, characters. More of a plot device than a fully fleshed out character in his own right, the true scale of Sentry’s abilities varies writer by writer, making his powers somewhat inconsistent.
Serving as the high-water mark for physical strength across the Marvel Universe, the Hulk is simply put, the strongest there is. Famously granted his powers following the explosion of an experimental gamma bomb, Bruce Banner was transformed into the terrifying Hulk in 1962’s The Incredible Hulk #1 and has remained one of Marvel’s most iconic heroes ever since.
Stan Lee has long stated that the introduction of Thor in Journey Into Mystery #83 was done with the intention of creating a character feasibly capable of challenging the Hulk. Boasting Hulk-level strength, Thor may not be quite as strong as his rival, but more than makes up for it with a whole host of other superpowers, ranking highly even amongst the vastly overpowered gods featured in Marvel Comics.
