Thanos didn't lift Mjolnir, Captain America did With
Other than Thor and Odin, certain other individuals have proven worthy of lifting Mjolnir in the primary continuity: Roger "Red" Norvell (a deliberate ruse by Odin) Beta Ray Bill. Buri (also known as Tiwaz, Thor's great-grandfather)
Yes, absolutely. The Infinity Gauntlet would easily give him the power to override Odin's enchantment, allowing him to hold Mjolnir whether he was worthy or not.
Thanos could lift Stormbreaker because he does not have to be worthy to do so, just powerful. And, Thanos stopped Mjolnir by grasping Captain America's hand. Because Thanos is so large, he grabs the Captain's hand and part of his wrist. He stopped the wielder of the weapon, not the hammer itself.
The hammer Stormbreaker is very similar to Mjolnir, made of mystic Uru metal and is nearly indestructible. Worthiness: Just like the original Mjolnir, no one can lift Stormbreaker who is not worthy.
Thor's hammer Mjolnir was defined by the fact that only the 'worthy' could lift it – so basically no-one except the god of thunder (and Vision, for some reason). But when it comes to the weapon's replacement, Stormbreaker – which Thor forges in Avengers: Infinity War – Groot is able to lift it too.
Both weapons also appear to have a degree of sentience, with Stormbreaker apparently being envious of Thor's affection for Mjolnir, a characteristic director Taika Waititi attributed to the handle being made from the arm of the adolescent Groot, and carrying over some of that character's moodiness at that age.
Why is this such a big deal? Well, for starters, the hammer in question, Mjolnir, can only be wielded by those who are considered “worthy,” a little mystical insurance policy put on it by Thor's dad, Odin. It's pretty cool to see the Avenger who is the purest of heart officially deemed “worthy” of the weapon of a god.
Yes, even Spider-Man has been worthy of holding the hammer of Thor.
Hela would win in a fight against Thanos. She is an incredibly powerful and skilled fighter. As the Goddess of Death, she has immense strength, durability, and regenerative abilities. She is also a master of weapons, particularly her lethal blades.
Ultron could not lift Mjolnir regardless of his mechanical status because his mind is twisted and evil, therefore he would not be worthy.
Avengers: Age Of Ultron Confirmed Iron Man Wasn't Worthy
Tony Stark was the second one to try, even joking about ruling Asgard if he lifted the hammer and what he would do as king, but his always overly-confident attitude quickly changed when he realized he couldn't lift the hammer.
Being a demi-god, Thor is capable of using all six Infinity Stones at the same time, perhaps even more so than the Hulk. Granted that he did gain weight in the five years since he ruthlessly beheaded Thanos in the garden after learning that he destroyed all the gems, he's still physically strong.
Venom (2020)
During this battle, Venom (Eddie Brock) was given the powers of Captain Universe, and was able to wield the hammer. However, Venom took this advantage a step further by merging Mjolnir with the Silver Surfer's surfboard to create an even greater weapon.
The firstborn child of Odin, Hela, wielded the power of Mjølnir before it ever came into Thor's possession. Hela used the weapon when she fought alongside Odin on their quest to conquer the Nine Realms.
Moon Knight even seized control of Mjolnir as he revealed that the Uru metal of the hammer is just another moon rock. So while Moon Knight couldn't physically wield the hammer, he could command it to obey his will. And that control extended to Khonshu as well.
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).
is Black Panther worthy of Mjolnir? the answer is actually yes. but it's not just t'challa. the whole Black Panther bloodline is worthy of Mjolnir.
And Mathaudhu can cite documentary sources to back him up. For example, Marvel – which publishes the Thor comics – issued a “Thor's Hammer” trading card in 1991 that states Mjolnir is made of Uru and weighs precisely 42.3 pounds. That's lighter than a herd of 300 billion mice, much less a herd of 300 billion elephants.
Imagine, Tony survived after End Game, he could have his own replicated Pym particles, had a time machine in his suit and even had access to each timeline in the multiverse. Dr. Strange believed if Tony Stark survived then sooner he will be the most powerful being in the universe.
Thor was worried Cap would lift Mjölnir in Age of Ultron, but was relieved in Endgame when Cap actually did it.
In the stories (and the Marvel movies), we see the god throwing the short-handled hammer at his enemies. The top of the Mjölnir often (but not always) comes to a slight point, giving the overall object a somewhat diamond shaped appearance. This shape is similar to an inverted Tyr rune.
Stormbreaker replaced Mjolnir upon the hammer's destruction in Thor: Ragnarok, and since Infinity War, it has been his weapon of choice. However, Thor: Love and Thunder once again gives this mighty Avenger a new weapon to wield, the lightning bolt (ahem, apologies, Thunder Bolt) of the famed Zeus (Russell Crowe).
The movie doesn't explain Thor's motivations for giving up Stormbreaker, but it makes sense that Chris Hemsworth simply wanted Love to have a powerful weapon to aid her in battle. It's unlikely that he could give her Mjolnir, considering that so few people in the MCU have been deemed worthy of its power.
It is safe to say that Stormbreaker cannot be destroyed by anything audiences have seen in the MCU so far. A power that Stormbreaker lacks is the "worthiness" enchantment of Odin. Anyone physically strong enough to lift and use Stormbreaker can use it.
