Thanos
When thinking of how powerful a supervillain is, it is not just about the special powers that they have, but what sort of evil they can accomplish. In that regard, it’s hard to deny that Thanos is the most powerful of them all.
The Fastest Superhero
Flash is the super fast superhero from DC Comics and part of the Justice League. Quicksilver is the super fast superhero from Marvel Comics and sometimes an Avenger. In recent clips, Quicksilver has blazing speed.
Superman vs. Avengers
If a fight broke out between Superman and the Avengers, the Avengers would defeat Superman. They could easily overwhelm Superman from all directions. Moreover, Ant-Man, Doctor Strange, and Thor, who possess magical powers could tactically defeat Superman.
Captain Marvel vs. Black Adam
One of the most powerful members of the Avengers, Captain Marvel has the powers and skills to take Black Adam out. While she’s probably not as strong as him, Captain Marvel is much faster and her energy absorption abilities would allow her to take any of his lightning strikes and just get stronger.
The Hulk vs. Superman
The Hulk Could Beat Superman, Marvel and DC, Writers Say. Although both Pak’s and Yang’s answers come with caveats and X-factors, both agree that the Hulk — either Bruce or Amadeus — would more likely get the upper hand on the Man of Steel. But Superman isn’t just a fighter, which makes all the difference.
Superman and Thor’s Hammer
So, there you have it: yes, Superman is capable of wielding Mjolnir, although he was only seen to have done so on an emergency basis — and, in fact, it appears that Wonder Woman is more unconditionally worthy of the weapon than he.
Thor vs. Superman
By most accounts, Superman seemingly outclasses Thor in terms of raw strength, especially in earlier versions of the DC Universe. He’s pulled planets, punched people into orbit and performed all sorts of wild feats of strength.
