Thanos didn't lift Mjolnir, Captain America did With
While many believed Thanos lifted Mjolnir during the Battle of Earth in Avengers: Endgame, a detail shows he knew he wasn't worthy of it. Avengers: Endgame saw all the heroes in the Marvel Cinematic Universe come together to fight Thanos and his armies and stop him from wiping out half of life in the universe again.
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.
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, even Spider-Man has been worthy of holding the hammer of Thor.
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.
How did Thanos manage to lift Stormbreaker? Thanos was able to lift Stormbreaker because the axe doesn't have worthiness enchantment as Mjlolnir does. Mjolnir is specific when it comes to the wielder's might since the only prerequisite to wielding is that the wielder is “worthy” of its might.
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.
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.
2. Thanos' Sword Is Made From Uru. Uru is a special metal in the Marvel universe that is said to only be created in the core of dying stars, making it ultra rare and incredibly strong. In fact, Thor's Mjolnir is made of the Uru metal making it comparable to Thanos's sword in terms of strength.
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.
Thanos is more powerful than Ghost Rider and would easily win in a battle. Thanos is stronger, faster, and more durable than Ghost Rider and has more varied powers and abilities, and with them, he can easily counter everything Ghost Rider can throw at him.
Thanos would win in a fight against Ultron in the comics and the MCU. Thanos has more versatile powers at his disposal. He is more durable and physically stronger. Thanos also proved to be an extremely experienced combatant facing the deadliest superheroes Marvel Universe could throw at him.
Magneto would still prove himself to be a formidable opponent. He would have been more than capable of wiping out Thanos' army of Outriders in Wakanda, as well as Proxima and Corvus of the Black Order.
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.
Cap has always been worthy.
In an interview with the Happy Sad Confused podcast, the Russo Brothers were asked why Captain America was able to lift Thor's hammer Mjolnir in Endgame when he seemingly couldn't in Age of Ultron. The duo replied “In our heads, he was [always] able to wield it.”
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.
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.
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.
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.
NOT WORTHY
The Dark Knight might be one of the least worthy heroes in any universe. While Batman does have some of the characteristics that would allow him to lift Mjolnir, he also has committed several acts that disqualify him.
Hence, Mjolnir determines worthiness based on Odin's definition of worthiness. However, since Mjolnir also has a conscious being within it, in the form of God Tempest, another likely explanation is that it is God Tempest that determines the worthiness.
One other reason could be that, because Vision is 'born' as a non-human, thus lacking in any of humanity's flaws (greed, anger, or wickedness), he is actually 'worthy' to wield the hammer.
King Thanos is an alternate-reality variant of Thanos from the Thanos solo run & Cosmic Ghost Rider storylines of Marvel Comics. He is a Thanos who defeated the Avengers and who is near victory in his genocidal quest.
