Armed with his new tools for battle, Thor defeats the Angry Titan by smashing his head with Mjolnir. In Avengers: Infinity War, Thor managed to lethally wound the Mad Titan with the Stormbreaker despite taking on the full force of the Infinity Gauntlet.
That villain is, of course, Kang the Conqueror, who's set to be the Avengers' next opponent in the upcoming Avengers: The Kang Dynasty. And while Thanos is certainly a hard act to follow, Kang may be a far greater threat than the Mad Titan ever was.
Thor: The God of Thunder almost killed Thanos in Avengers: Infinity War. He really would have taken down the Mad Titan there and then if not for his wish to see Thanos realise the error of his ways. As Thanos said, he should have gone for the head. We think if Thor got another chance, he would not miss.
Ant-Man and The Wasp: Quantumania director Peyton Reed hints at Jonathan Majors' Kang the Conqueror as a bigger villain than Thanos.
So, there you have it. Thanos beats Hulk every time, with or without the Infinity Gauntlet. But World Breaker Hulk defeats Thanos. However, Thanos could beat the Hulk if he had the Gauntlet (He could wipe out the Universe).
Superman has beaten everything the Multiverse has thrown at him and always come back for more. He's faced Thanos's type many times and always won. Superman is vastly more powerful and skilled than Thanos. It wouldn't take him long to realize how dangerous the Mad Titan was and once he did, he'd take the kid gloves off.
Bigger than his enemies, bigger than his family, bigger than any other cosmic threat, Thanos's greatest weakness will always be himself. We've discussed his ego previously, but it's his insecurities about his own worthiness that will ever prove to be his downfall.
As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
The theory posits Ego, Odin, and The Ancient One as three of Thanos' greatest fears, and he waited until all of them were dead to make his move. This would make sense, as all of these characters were massively powerful and had strong ties to the Avengers, which meant they could be called in for backup at any time.
Kang is more powerful than Thanos
Thanos certainly presented the Avengers with a challenge, and his power continued to grow as he amassed the various infinity stones. Kang, though, seems to have almost limitless power once he can access even one aspect of his hyperadvanced technology.
Iron-Man. Of course, this is the man who is actually able to defeat Thanos in the end, sacrificing himself in order to kill him. He loses his own life to do that, proving just how unselfish he is at his core, with Iron-Man's power and strength of character being the overwhelming power for him.
Spider-Man used the Infinity Gauntlet against Thanos and restored the universe after he snapped half of life from existence - but nobody remembers. One of Spider-Man's greatest victories is a fight his fellow heroes don't remember, as the web-slinger's defeat of Thanos with the Infinity Gauntlet is only known by him.
While it is fairly obvious that the Flash could run circles around Thanos under normal circumstances as his powers make him virtually untouchable, there wouldn't be much the Scarlet Speedster could do if he was around for Thanos' Infinity Snap as there is no way to outrun the god-like power of cosmic chance.
Thor, the god of Thunder, was undoubtedly the most powerful member of the original Avengers. His power continues to grow in the Marvel Cinematic Universe.
Based on the analysis of powers, speed, strength, durability, and combat, we can safely say that Odin is stronger than Thanos and outmatches him in almost every aspect. Thanos might be among the most feared villains in the Marvel Universe, but he comes nowhere near when compared to All-Father Odin.
Spider-Man may be one of the strongest Marvel heroes around, but Captain America was still the best soldier alive. Cap's experience always beat Spider-Man's raw strength.
Although Ghost Rider is certainly a skilled superhero, in a fight with Thanos, it's quite clear that Thanos would win. The reason for this is that technically, Thanos is immortal. In the comics, he was freed from the dead zone by Death with whom he had a relationship. Ghost Rider would with the fight with Thanos.
Spider-Man is stronger than Batman and would ultimately win the fight against him. He is more powerful, faster, and due to his high intelligence, Batman would have trouble devising a plan that would work against him.
Thor is strong; Wanda is powerful. Power doesn't have to mean raw strength, but the tremendous demonstration of one's own ability. Thor could beat Wanda in an arm wrestling contest, but Thor is still susceptible to Wanda's mind powers. And we've seen that before, in Avengers: Age of Ultron.
As mighty as they are, neither Thanos nor Superman is immortal. Both have been killed in the past, meaning neither is unbeatable. However, Thanos would need an ironclad plan to trap and defeat the Man of Steel, because if it comes down to plain old fisticuffs, Superman is definitely going to win.
Hercules / Zeus
He ranks above Thor here because he's technically the stronger of the two. In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
Galactus (Marvel)
He can only sustain himself by consuming entire planets. Galactus's villainy and evil nature make him the strongest comic supervillain.
