According to the commentary track on the Endgame Blu-Ray, Thanos' sword comes from somewhere off-world, making it stronger than vibranium and quite a number of other things as well. Thor's weapons can't scratch them, for instance.
The vigorous and sturdy composition of Thanos' sword could be cosmic in nature, derived from the Celestials. Beings known to have the ability to mold matter itself, it's plausible that the Celestials would craft a tool proficient to beat the best the Nine Realms have to offer, even Uru and vibranium.
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.
It hasn't been explained in the comics what Thanos' armor is made of, but we can assume it's a really strong metal. There is a version of Thanos where we know exactly what his armor was made of, however, and it was alive.
Thanos is crazy strong and using his Vibranium double-edged sword against Cap's Vibranium Shield, he is able to break the shield. In conclusion, Thanos' blade is not made of Uru instead its made of Vibranium.
In the MCU, Thanos is large and muscular because he was born with a genetic condition that made him both purple and much larger and stronger than the average titan. He was exiled from his planet when he was a young adult, and spent most of his life outside of Titan.
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.
Thanos Beat Hulk Because He Was A More Skilled Fighter
Hulk's defeat could be because Thanos possessed the Power Stone, but with Thanos never pulling it out in the fight, the Russos believe that he didn't need it to win. Despite his great strength, pre-Avengers: Infinity War Hulk did not often fight with a strategy.
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.
Physically they're pretty evenly matched, but Thanos is just a much more skilled fighter. No stones were used in the fight. Per Joe Russo: "I would say that he's just that powerful," said Joe Russo.
Vibranium is just the strongest metal on Earth. In Endgame we see that Thanos' blade is able to break Cap's shield. There are much stronger materials in space, it stands to reason that there are beings out there stronger than it as well.
Mjolnir doesn't damage Cap's shield at all, as shown below. I think it is fairly safe to assume that Stormbreaker (being a cutting weapon, rather than Mjolnir which is designed to smash or build) would inflict similar damage to the shield as Thanos sword does. Conclusion: Stormbreaker minces Cap's shield.
Well, considering that Tony was able to make Thanos bleed when Thanos did have the stones, I would think that Tony would be able to defeat Thanos if he didn't have the stones. In the GIF above Tony can be seen using Mark 50, his first suit made of nanotech. The last suit Tony used when battling Thanos was Mark 80.
Can Tony Stark's God-Killer armour defeat Thanos with and without the Infinity Stones? Yes, absolutely. The God-Killer Armour was designed to fight Celestials.
This truly showed Scarlet Witch as being stronger than Thanos, as she destroyed his sword and would have killed him were it not for his plan to rain fire from his ship. The main reason as to why Wanda was stronger has since been established in the MCU with the release of Phase Four's first project, WandaVision.
“People have speculated whether there was some fear on the Hulk's part about having to face Thanos again,” Russo said. “But I think ultimately what it is, is that he's tired of playing hero to Bruce Banner.” It's not the first time the Russos have said something to this effect.
Thanos would win round one. Thanos is physically superior and far more durable than Thor. In a hand to hand fight Thanos would beat Thor into a bloody pulp. I am also curious to know if Thanos can control cosmic energy outside of the gauntlet.
Only with the power of the Infinity Stones does Thanos stand a chance of beating Galactus in a fight; it's fortunate for him (and for the universe) that Galactus considers himself above such moral concepts as good and evil, choosing instead to eat planets out of a desire to satiate his hunger rather than a desire to ...
He transported Thor back to Asgard where Odin took this as an act of war and fought an extremely destructive battle with Thanos. Even upon learning the truth, Odin did not thank Thanos for his reluctant altruism, but told him to leave and never return.
On a normal day, Zeus would wreck Thanos, but he is never winning while Thanos has the Infinity Gauntlet. Thanos using it makes him the strongest being in the Marvel universe. To recap, Thanos using the Infinity Gauntlet killed half the living things in the universe with a thought.
Endgame Thor was weaker not only because he wasn't in the best physical shape(fat) but because he was also mentally burdened. To get to the root of this we have to consider the events that led up to Infinity war. First of all,he was Banished by his father(Odin) banished him to earth for his arrogance.
As Cates has pointed out on Twitter, it's important to point out that “Thanos” is still Thanos' real name, and that “Dione” was what his mother originally wanted to call him before he was born.
