Fernus infiltrated the Phantom Zone by telepathically stealing Superman's access codes and travelling to the Fortress of Solitude before the League could open the Zone and try to question a White Martian about Fernus. Fernus is eventually defeated by Plastic Man in a last desperate confrontation.
First of all Zeus and Superman fought in the Injustice storyline. Zeus won it, However, if you don't consider it as canon then…. Zeus defeated the shatter god.
If you're not a hardcore DC fan, you could be forgiven for thinking this as Superman is generally the strongest hero talked about in DC. However, it's actually Martian Manhunter that would easily win against Superman in a fight.
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.
As Skyfather of Olympus, Zeus wields power comparable to Odin, whose wrath Thanos has withstood but not bested. At the same time, Zeus cannot truly die. While the most powerful of Olympians can be badly wounded or even dismembered, he can never actually pass on into oblivion.
The two Justice Leaguers might possess an even amount of base strength, but Manhunter's combined powers give him the edge. To emphasize this, Superman himself said that J'onn is the most powerful being on Earth.
It was revealed during the Trial By Fire storyline that the Martian weakness to fire is a built-in psychosomatic effect, placed in the Martian race long ago by the Guardians of the Universe to prevent them from reverting to a previous evolutionary state in which they were highly aggressive, on the verge of interstellar ...
It requires a considerable amount of training to master. Super strength: Martians are stronger than humans, though not as strong as Kryptonians. Durability: Martian bodies are denser than a humans but not nearly as durable as a Kryptonian.
His unique physiology enables him to achieve a multitude of abilities, such as; Flight: Martian Man can comfortably fly in Earth's atmosphere. Shapeshifting: Martian Man's physiology allows him to shapeshift, an ability shared by the Martian Race.
This is an interesting question because you picked Martian Manhunter, whose weakness is fire. But it's not a weakness in the same sense as kryptonite is to Superman. It's not physical, it's psychosomatic. All Green Martians have a deep seated psychological fear of fire.
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.
It's important to note that the rules around worthiness had been temporarily suspended to allow this to happen. As soon as the fight was over, Superman couldn't lift the hammer anymore. However, under normal circumstances, without any weird interference, Superman is worthy of Mjolnir.
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.
Hulk has taken on Marvel gods like Thor before and come out victorious, but Zeus represents a much more powerful opponent. The Olympian easily defeated the Hulk and tested his healing factor in their fight.
As such, Zeus decides to grant the Hulk's request to beat him to death in hand-to-hand combat. The Hulk's first blow sends Zeus crashing into a nearby building. Zeus then returns this with an even more powerful blow. The ruler of the Olympians than overpowers the Hulk, and ultimately knocks him off Mount Olympus.
So while Zeus' best feat is defeating a mountain-sized monster, Odin's best feat is defeating a monster as big as nine worlds. Odin outclasses Zeus in intelligence, versatility, strength, and weapons. Zeus simply can't compete. The winner is Odin, All-Father of the Æsir.
Likewise, if Hal Jordan was fighting without Nezha's power, Superman could easily break through his constructs. Thus if Superman fought a Green Lantern one on one, Alan Scott would be the only one who could defeat him. Batman/Superman: World's Finest #4 is now available from DC Comics.
Superman could easily take on one or two members of the Green Lantern Corps, but taking on a whole army who can create and wield Kryptonite out of nothing may be too much even for the Man of Steel.
