Superman can bench 5.972 sextillion metric tons. And, almost certainly more than that. At the time I first heard this, I was of course dumbfounded by the sheer magnitude of it. And back then, it just seemed the latest in a line of limitless powers he had demonstrated.
This difference in gravity allows Superman to lift objects that measure in the tons. In fact, the comics have put Superman's strength at a point where he's able to lift around 2 billion tons! To put that into perspective, the Empire State Building is only 365,000 tons!
Yes, Superman legitimately lifted the weight equivalent to the entire mass of the earth and based on the context of the story, that reveals even greater strength.
For five days, Superman has been bench-pressing Earth's weight on a specialized machine. As Superman finishes his exercises, Dr. Veritas takes a drop of sweat from his forehead to analyze it. Astonished, Superman says he no longer remembers the last time he sweat.
Batman's Strength Is On A Nearly Superhuman Level
In Batman #655, Bruce is shown to be bench pressing over 1000 pounds during one of his regular workouts. In Batman Odyssey #2, Bruce mentions that his maximum leg press is 2500 pounds.
UNLIMITED STRENGTH
The answer; there isn't one. The amazing thing about the Hulk is that unlike nearly every other superhero ever created, the Hulk's strength has absolutely no upper limit. He can lift a commercial airplane – which weighs around 100 tons – when he is at his calmest; that's no problem for him.
The adamantium renders his bones virtually unbreakable and his claws capable of penetrating almost any substance depending on its thickness and the force he exerts. His reinforced skeleton also enables him to withstand heavy physical pressure, giving his muscles sufficient force to briefly lift 800 pounds or more.
Captain America can lift 800-1400 pounds just as a warm-up, but when under duress or in emergencies, this number steadily increases.
To make things clear, Superman has lifted Mjolnir in comic books. In 2003, when Marvel and DC co-produced JLA/Avengers #4 to defeat the ultimate villain Kronos, Superman was able to wield Thor's hammer.
However, most sites and commentaries estimate that Thor can lift over 100 tons, which places him in the Class-100 strength category. This is the same category that the Hulk is in. In Marvel's strength scale database, Thor is listed in the “able to lift over 100 tons” category. This confirms this minimum lift.
Despite remaining one of the most powerful heroes, Superman's strength has waxed and waned over the years. The Spectre is unlimited in his strength, making him stronger than Superman at his best. Spectre's role as the divine Spirit of Vengeance makes him one of the most powerful beings in existence.
Shazam gets his immense god-like strength from the demigod Hercules who is widely known for his numerous feats of strength. By invoking Hercules's power, Shazam can lift over 100 tons.
In the first stories about Superman's origins, all Kryptonians possess on their homeworld the same powers Superman has on Earth. In later depictions, their abilities are attributed to the differences between Earth's gravity and that of Krypton and the different radiation of the stars they orbit.
The Incredible Hulk, on the other hand, has a very different relationship to strength than Superman. While the Hulk's “baseline” level of strength only allows him to lift about 70 tons – a meager amount compared to Superman's lifting power – that level can quickly change as he gets angry… and he's usually furious.
In Superman All Star when he was supercharged by being in direct contact with the sun, his limit was found to be 200 Quintillion tons, which would put Superman's maximum lift limit is 66.67 Quintillion tons when not under the effect, but he felt like he could do more, so that shows he's not actually straining himself ...
Captain Marvel, aka Shazam, is one of the most powerful heroes DC has to offer. He's on Superman's level, though Shazam's powers are derived from magic. However, being powerful is not what makes Shazam worthy of Mjolnir. In fact, Shazam is not the one who is worthy of the hammer; Billy Batson is.
When he gets really supercharged by the sun, Superman's strength levels are virtually limitless. Once, in All Star Superman, he entered the sun to save a team of scientists and ended up able to lift 200 quintillion tons… with one hand.
He's best known for his fiery omega beams, but he also possesses super strength. That said, how much can he lift? Darkseid's strength level is considered Class 100. This means he can effortlessly lift 100 tons, and in extreme cases, even exceed this limit.
Like his namesake, Spider-Man's strength and agility stand far above those of the average human, allowing him to lift nearly ten tons and to leap and move at incredible speeds with high accuracy. He also heals faster than normal when injured, though he is not completely immune to viruses and other human ailments.
Batman has been able to showcase his ability to lift over 1,000 pounds using his upper-body strength. He built his upper body well enough to carry incredible weights.
According to his official Marvel page, Spider-Man is capable of lifting up to ten tons, and that means that he is a lot stronger than some of the other characters that have peak-human strength. However, Spider-Man's strength pales in comparison to the likes of Thor and the Hulk.
Superhuman Strength: Deadpool is rated as having a low degree of superhuman strength allowing him to lift 800 pounds. Peak Human Speed: Deadpool can run as fast as a trained athlete.
On average, Deadpool can actually lift as much as two tons!
It's estimated that Black Panther can lift up to 800 lbs which is around 363 kg, and is borderline superhuman but not quite. Despite this limit, Black Panther is known to wrestle with enemies far stronger than he is.
