Superman and the Xenomorph though appear to be on the opposite end of the power spectrum. With Superman's invulnerability, X-Ray Vision, and super-strength there's no way the Xenomorphs could hurt him, no place they could hide from him, and no chance they'd survive his onslaught.
Boomstick: For one thing, the Predator was comparatively tougher than the Xenomorph. It could take numerous gunshots with only minor wounds, yet a single round from any high-caliber gun is enough to put a single Xenomorph down.
As the dialogue in Justice League #73 suggested, while Superman's specific vulnerabilities give Black Adam a chance against him, that doesn't mean the two are equal in power, and the Man of Steel is clearly stronger by any comparison.
This gives him super-strength on par with heroes like Superman and Wonder Woman. Aquaman also wields a mystical trident that could exploit Superman's alternate weakness to magic. Aquaman's strength could give his mystical trident enough force to potentially stab Superman if the two ever faced off in a fatal battle.
The Man of Steel Meets the Xenomorph: Superman/Aliens - Explained
Who can Superman never beat?
Superman is very vulnerable to telepathy. This is going to make defeating Martian Manhunter impossible for the Man of Steel. In fact, it would make it hard for anyone to defeat Martian Manhunter, since he could puppet Superman around from afar.
Bigger Brain, Better Problem Solver. Queen Xenomorphs are more intelligent than any warrior or even their protectorate Praetorians. In some cases, Queens are said to have an IQ of 175. They're intelligent enough to use human technology, or at least figure out how to use an elevator while hunting.
the queen mother is the strongest. mainly because she is the biggest and she has direct control over any alien she can think of. she lives in the world hive which you could guess is our world as an alien hive. The Queen Mother is the most powerful of all Plagiarus praepotens, bar none.
Godzilla's strength has been officially confirmed to be greater than Superman's, as shown in Justice League vs. Godzilla vs. Kong #2 preview. This feat of strength proves that Godzilla can easily defeat other Kryptonians, such as Supergirl and General Zod.
There's no question the Hulk is a near-indestructible force who comes out on top in almost all of his battles of pure strength. However, against Superman, he's outmatched. While Hulk's strength might rival that of the Man of Steel, Superman's other abilities give him a considerable edge against his opponent.
While Superman could potentially overpower Thor, blows rendered by the mystical Mjolnir would likely impose serious damage on the Kryptonian hero. With his super-speed, the Man of Steel could probably avoid the Thunder God's lightning, but not necessarily, since Thor is just as fast.
A core part of Superman's appeal is that he's basically indestructible, which is why it's so surprising that even he can fall victim to Alien's insidious Xenomorphs. While it took some very special circumstances, one comic proved even Clark Kent isn't immune to the world's most famous extraterrestrial threat.
Wiz: The Demogorgon may have been the deadliest predator in the Upside-Down, but the Xenomorph was simply a few leagues above it. The Demogorgon may be capable of smashing through brick, but Xenomorphs can tear through steel; a pretty clear difference.
In most of the films, adult Aliens are capable of running and crawling along ceilings, walls, and other hard surfaces. They have great physical strength, having been shown to be capable of breaking through welded steel doors over time.
Tight spaces may slow them down a little, but it's still impossible for a human to truly outrun them. Xenomorphs are horrifying creatures for numerous reasons.
Despite their tough and seemingly impenetrable exoskeletons, Xenomorphs are not bulletproof. Well-placed shots can kill them, although it may take multiple hits to take down one of the larger and more formidable specimens.
Superhuman Strength: Yautja are incredibly strong. They have been portrayed as being easily capable of outmatching a conditioned adult human male in combat, shattering solid concrete with their bare hands, ripping the heads and spines out of humans, and effortlessly breaking through steel doors.
Xenomorph blood is a potent molecular acid that Xenomorph XX121 contains within its body. A highly corrosive substance, it is capable of burning through virtually any natural or man-made material in short order.
Superman wins. Korra may be able to master all 4 elements but Superman can evaporate an ocean with his eyes, lift thousands of tons, and destroy virtually anything in existence.
However, in recent years, Iceman's powers have been expanded to their logical degree and they would give him more than a chance against Superman. Superman could smash his way through Iceman's ice constructs pretty easily and that would give him a false sense of security in the fight.
The comics have shown the former Captain Marvel best Superman in a one-on-one fight while players of the Injustice video game watched Superman defeat Shazam by freezing his mouth shut --so he couldn't say the magic word-- and promptly lobotomizing him with his heat vision.
