Captain Marvel is not immortal, but her aging has been significantly slowed down; this is why it appears that she hasn't aged a day since she gained access to her powers.
In the comics, Rogue wrecked Carol Danvers completely when she got in contact with her and stole her powers. She not only stole her powers but all her thoughts and feelings too. Captain Marvel is vulnerable to all those mutants who have the capability of power stealing. What is this?
Captain Marvel vs Thor. The short answer is no, Captain Marvel is not stronger than Thor. In Marvel comics, the Asgardian is infinitely stronger than Carol Danvers. As for the MCU, it's not very clear but assuming their strength levels are somewhat equal, that still makes Thor the clear victor overall.
Danvers is depicted as a former U.S. Air Force fighter pilot who was given superhuman abilities when a light-speed engine test went wrong and she was exposed to the cosmic energy of the Tesseract. She was subsequently transformed into a Human-Kree hybrid via blood transfusion and renamed Vers.
Hulk. In terms of sheer physical strength, the Hulk could easily out-muscle Captain Marvel. The superheroine's slew of other powers would make defeating the Hulk a walk in the park. Unlike the Hulk, Captain Marvel's superhuman abilities are always on hand.
Beyonder
With a simple thought, the Beyonder can displace an entire planet, change the rules of physics, and even destroy the entire universe. That's why the Beyonder was presented in Marvel Comics as the most powerful being to ever exist.
Captain Marvel is the most powerful and powerful Avenger in the Marvel Cinematic Universe (MCU). Her incredible powers and determination have made her a valuable member of the Avengers.
The Verdict: Scarlet Witch Is Stronger Than Captain Marvel
That said, Wanda has an edge due to Chaos Magic and her reality-warping abilities. Her telekinesis alone could nearly kill Thanos faster than Carol's punches. Now, as the Scarlet Witch, she doesn't even have to move objects with her mind to get what she wants.
For all his faults, Cap is undeniably a noble, selfless, and pure-of-heart hero who's perhaps more worthy of Mjolnir than anybody else in Marvel (or DC, for that matter).
In my mind the answer to that is Barry Allen. While he's not the “original” Flash, he is the one that made the name famous. Barry Allen was the fastest man alive for many years. He even sacrificed himself to save the universe and ended up in the Marvel Universe.
Hawkeye. On numerous occasions in the comics, Clint Barton has said he's just a regular guy with a bow and arrow. Unfortunately, his lack of power usually leads to him suffering injuries regularly and has led to fans deeming him the weakest member of the Avengers.
Although the vast majority of Carol's Binary powers have been lost, she still retains the ability to absorb energy and fire photonic blasts from her hands. If Carol is exposed to enough energy, her full Binary powers have the potential to temporarily reemerge.
Able to regenerate from any and all injuries, including death, Craig Hollis is unable to die and therefore dubs himself Mister Immortal, vowing to fight crime. With the two-dimensional Flatman, they form the Great Lakes Avengers in the Wisconsin area, despite lacking official Avengers sanction.
Thor. Thor is the oldest official Avenger at about 1,505 years of age. He mentions his age for the first time during Avengers: Infinity War, which would put his birth date around 518 CE. However, some sources say that Thor's birth date is around 965 CE, but this might be information from the comics.
In Avengers: Endgame, Captain Marvel could hold off Thanos while he held the Infinity Gauntlet.
Tony Stark is the smartest of them all, having been responsible for some of the most incredible inventions to have ever graced the Marvel universe, including the Arc Reactor and one of the most sophisticated artificial intelligence systems known to man.
But after the release of WandaVision and Doctor Strange in the Multiverse of Madness, it's pretty clear that the Scarlet Witch is among the most powerful. Wanda Maximoff has never truly been defeated, only "losing" to the combined forces of Doctor Strange, Wong, and America Chavez after realizing the error in her ways.
While Quicksilver is often thought of as the fastest of the Avengers, one hero fans know from the movies can actually outrace him when they need to. Many heroes possess enhanced speed, but Pietro Maximoff is generally considered Earth's fastest man (at least in Marvel Continuity).
The Avengers, led by Chris Evans as Captain America, assembling in the Battle at the Avengers Compound. The Battle at the Avengers Compound sequence was praised by /Film as an improvement from Avengers: Infinity War, while scenes from the sequence were positively received by cinematic audiences.
2) Captain Marvel
Even if Carol Danvers isn't around much, it's her who turns the tide of battle in Avengers: Endgame. She holds her own with Thanos in hand-to-hand combat for longer than Thor, Iron Man, or Steve Rogers, and takes down his enormous warship single-handedly.
United States. The United States of America is a North American nation that is the world's most dominant economic and military power.
