There also appears to be some mental strength required too based on the end of Thor's warning, so that part of Steve didn't come from a bottle. The other aspect of Captain America that could explain his ability to hold Stormbreaker is that he also previously held Mjolnir.
How Can Captain America Lift Thor's Hammer? Simple: Steve Rogers is worthy. The inscription on Mjolnir reads “Whosoever holds this hammer, if they be worthy, shall possess the power of Thor.” It doesn't matter how strong you are, if you aren't worthy, you can't lift Thor's hammer, no matter how hard you try.
Can anybody lift it? Stormbreaker doesn't have a worthiness enchantments like Mjolnir, since Odin wasn't alive to give it one, so as long as a character is strong enough, they can lift the axe.
Stormbreaker can also be summoned by those worthy of lifting Mjølnir, as shown when Captain America, who was previously proven worthy of wielding the hammer in his fight against past Thanos, summoned Stormbreaker by mistake some moments later during the Battle of Earth.
How come Captain America couldn't lift Thor's hammer?
It turns out the secret he was keeping about Tony Stark's parents – that Bucky (Sebastian Stan) was behind their deaths –was weighing on his mind, making him “not completely worthy” of wielding it.
It's important to note that the rules around worthiness had been temporarily suspended to allow this to happen. As soon as the fight was over, Superman couldn't lift the hammer anymore. However, under normal circumstances, without any weird interference, Superman is worthy of Mjolnir.
Steve Slightly Moves Mjolnir In Avengers: Age Of Ultron
This went on until Steve Rogers tried, and while he didn't exactly lift, he was able to move it ever so slightly. Not only did this surprise Thor, but it also raised questions about Captain America's worthiness.
This is a very simple answer that a lot of people don't understand: You don't need to be worthy to lift Stormbreaker! Unlike Mjolnir, Stormbreaker was never enchanted by the forefathers to only be held by the “worthy”. It was simply a powerfully forged weapon with near-indestructible properties. Cliff G.
Here's what Thor says about Stormbreaker (and general, powerful dwarven weaponry) in Infinity War: “You simply lack the strength to wield them. Your bodies would crumble as your minds collapsed into madness.”
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.
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.
Gorr the God Butcher possesses enhanced strength, durability, and agility due to his alien physiology and absorption of divine energy. Stormbreaker, a powerful enchanted weapon forged by Eitri, allows beings of sufficient strength, like Gorr, to wield it.
Loki is confirmed to be worthy of lifting Thor's hammer, Mjolnir, for the first time in official Marvel canon. In The Immortal Thor #5, Loki confidently catches and wields the hammer, showcasing his growth and heroism.
Clearly, Thanos is aware he wouldn't be able to lift it. Although it's hard to pinpoint what exactly makes someone worthy of using Mjolnir, as it's ultimately determined by Odin, who placed the enchantment on the hammer, some believe one's worthiness is measured by traits like courage, honor, and selflessness.
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.
Why did Stormbreaker overpower the Infinity Gauntlet?
Infinity gauntlet and stormbreaker are made out of the same metal, same forge. That is why stormbreaker was able to sustain those beams coming out of the gauntlet.
I think, quite simply, he underestimated both Stormbreaker and this more godly Thor. He had the power to simply snuff Thor from existence or fire a beam that nothing in the universe could stop. Or anything else he could imagine.
During a Vudu Viewing Party for Avengers: Infinity War, co-directors Anthony and Joe Russo revealed a key difference between Thor's hammer Mjolnir and his new ax Stormbreaker: the latter doesn't require worthiness. That's why Groot was able to lift the ax, not because he was worthy but because he didn't need to be.
Storm breaker is meant to be the strongest weapon of Asgard and could even summon bifrost, says Eitri. But there is no enchantment or spell on it like it was on Mjolnir. So one doesn't have to be worthy to weild it, just the strength to lift it. Clearly Thanos is capable of lifting it.
Actually everyone can lift Stormbreaker. Odin's enchantment was only for Mjolnir not for any other weapon which he would use in future. That is why Thanos was able to lift Stormbreaker and he was not worthy of Mjolnir.
Can Stormbreaker destroy Captain America's shield?
Because it was dead-set in the middle. Captain America's shield is strongest in the middle and weaker on the outsides. That's why Thanos was able to break it. So with a bladed weapon of his own and hitting the sides, Thor could indeed break it.
However, when Captain America attempts to lift it, it moves slightly, showing concern on Thor's face. If the Russo Brothers' thoughts are correct, Cap was really just showing humility and spared Thor's ego by not fully lifting the hammer.
As it turns out, 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 led the charge once reinforcement arrived – the MCU's Steve Rogers rightfully fits the bill.
Shortly after, most of the world's superpowered beings are killed during Ragnarok, leaving only Black Widow, Nick Fury and a handful of others alive. In her desperation, Natasha was able to lift Mjolnir and received an awesome new costume that looked like a cross between Jane Foster's Thor and Valkyrie costumes.
