Cap has always been worthy. The duo replied “In our heads, he was [always] able to wield it.” “He didn't know that until that moment in Ultron when he tried to pick it up,” continued the Russos.
Although Cap's internal conflicts prevented him from being fully worthy to lift Mjölnir during Age of Ultron, Cap really almost pulled off stealing Thor's thunder.
Captain America could've lifted Mjolnir, he didn't almost lift it. He could've lifted it if he wanted to, but he chose not to. There's a popular theory going around that Cap couldn't fully lift Mjolnir because he was only partially worthy. He only became worthy after revealing to Tony that Bucky killed his parents.
Cap probably got a small strength increase, but not on Thor's level. His striking power wasn't that impressive. Even in infinity war, he was strong enough to hold back an arm of Thanos (it was PIS, but Thanos did try putting more effort and couldn't push him back so he used the other arm).
Mjolnir has been manipulated in different ways in Marvel Comics, and many years ago, Iron Man was able to hold the hammer… thanks to zero gravity, meaning that he didn't properly lift it and he would have still not been able to wield it on Earth because he wasn't worthy.
If Marvel fans have ever wondered if Spider-Man was worthy of lifting Thor's hammer, the answer is yes. Just NOT the Spider-Man you think… Although he didn't really meet Thor beyond a couple shared scenes in Avenger's Endgame, Spider-Man has shown he's actually a big fan of the Thunder God.
Meanwhile, MCU Phase 4 saw Stormbreaker being wielded by Thor, Gorr the God Butcher, Love, and anyone else who was strong enough to actually lift and swing it. This is because of the respective origins of both legendary Asgardian weapons.
Basically, he could. It is definitely possible because if Superman was exposed to kryptonite beforehand, he would not have his powers. This would allow anything to be able to beat him. However, Superman would beat Captain America with Mjolnir if he had his powers (which he usually has).
Captain America may well be one of the greatest fighters in the Marvel Universe, but even years of combat experience and an unbreakable shield can't match Thor when it comes to sheer power.
Thanos might be stronger and have the Infinity Gauntlet, but the heroes have taken it from him before and they could do it again. Captain America never gives up and even if he fails at first, he'll eventually find a way how to stop Thanos once and for all.
It turns out that Mjolnir is not simply looking for a warrior, no matter how righteous, but rather the first warrior into the fray. As the last man standing against Thanos - and the one who leads the charge once reinforcement arrive - the MCU's Steve Rogers rightfully fits the bill.
Stormbreaker has the additional power to summon the Bifröst, allowing Thor to teleport anywhere in the Nine Realms. Screen Rant has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
Make-believe metal is kind of hard to weigh. But then, in 1991, Marvel released a "Thor's Hammer" trading card that claims that Mjolnir weighs precisely 42.3 pounds. Yet, using the dimensions and weight on Marvel's trading card, it's estimated that the density of Mjolnir is about 2.13 grams per cubic centimeter.
Is Thanos able to lift Mjolnir? No he didn't. He caught Stormbreaker, which, as far as we know, simply requires a great amount of power to wield, far more power than any human has, but presumably power that Thanos has. He never once lifts Mjolnir.
The Asgardian Son of Odin was extremely close to ending Thanos at the end of Avengers: Infinity War. After gaining the powerful weapon Stormbreaker, Thor becomes the wielder of the most powerful weapon in the universe. Stormbreaker is capable of killing Thanos outright, and only Thor is currently worthy of wielding it.
1 #230, Hulk defeated Captain America easily. However, it's still impressive to see Cap beat up one of Marvel's strongest characters using only his fists and his shield—with some help from Spider-Man.
Writers often take artistic licenses when dealing with Hercules' strength, as Stan Lee himself pointed out at one time. However, it is undeniable that Hercules has bested both Thor and Hulk, proving he is indeed the strongest Avenger.
Moon Knight also has the ability to lift Mjolnir as it is made from Uru, a metal ore from the moon of a dead universe. So, with the help of Khonshu's influence, Moon Knight has the ability to control the hammer. Two DC Comics characters have lifted Mjolnir in Marvel/DC crossover events: Wonder Woman.
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.
He has feats such as defeating Surtur (who can destroy a planet), conquering the 9 realms, and sealing away Hela. While there isn't much doubt that Thanos could beat Odin if he had all 6 stones, Odin could probably defeat Thanos if he only had one or two of them.
Can Stormbreaker destroy Captain America's shield?
Stormbreaker is made of the same metal as Mjolnir, which was unable to damage the shield, but is more powerful and has the sharp edge that Mjolnir lacked. Thor himself is also more powerful than during those previous encounters. Yes. Uru metal can quite easily break vibranium.
Groot isn't worthy, he doesn't need to be worthy to pick up two unfinished parts of the weapon and join them. Stormbreaker is not blessed with odin's blessing it does not matter if he is worthy he can still pick it up. Anybody can lift it now kind of taking away the permanent leverage.
