Galactus was killed by Thor during the "Herald of Thunder" story arc in Thor (vol. 6) #1–6 (March–August 2020), and reappeared after a two-year hiatus in Fantastic Four (vol. 6) #45 (July 2022)—the final issue of the event "Reckoning War"—where Galactus is resurrected by his former heralds.
With the Ultimate Nullifier having been destroyed, Quill eventually defeats Galactus by shooting him in the head with the Time Stone, displacing part of Galactus's brain. With the death of Galactus, most of the Church are revealed to have been brainwashed thralls who break away.
Odin is basically Thor and all the other Asgardians rolled into one—though he's even wiser, more experienced, and minus one eye. As the default King of Asgard, Odin is easily the most powerful being in his realm.
The Asgardians put up a valiant fight, with Odin famously headbutting Galactus in the face during the battle as well, but it was all futile as Galactus is a force of nature that is not easily destroyed.
Despite the fact that Galactus is a cosmic being older than the universe who regularly consumes entire planets, the earthbound Juggernaut shockingly proves to be more powerful than him–and one stunning side-by-side comparison confirms it.
Galactus would easily defeat Dormammu outside the Dark Dimension, but it turns out that even on Dormammu's turf, he retains his power and has the means to grow even stronger.
There was one time in the comics when Deadpool faced Galactus head on, and somehow won. Instead of slicing the giant to pieces or punching through his heart, Deadpool just talked and talked - and talked. Indeed, Galactus got so annoyed by Deadpool's quips that he eventually surrendered.
Star-Lord has several insecurities and personal demons to contend with, including his feelings of inferiority around stronger, cooler men like the mighty Thor Odinson. This weakness was glaringly obvious in 2018's The Avengers: Infinity War, where Star-Lord immediately felt threatened by Thor when they met.
While that may technically be true, it wasn't until the holiday special came out that fans learned the full story. Mantis is actually Peter's half-sister. As it turns out, Mantis is one of the many children Ego created on his quest for power.
Terrax next led Galactus back to Earth, hoping the Fantastic Four could again defeat him, but Galactus stripped Terrax of his power and cast him out. The Fantastic Four, Avengers, and Dr. Strange defeated the exhausted Galactus, but as the world devourer lay dying, Reed organized efforts to save him.
The Fantastic Four. The Fantastic Four had the privilege of being the first superhero team to take on and defeat Kang the Conqueror. After Kang traveled through time and conquered Ancient Egypt, the Fantastic Four found themselves also traveling through time and battled Rama-Tut, ousting him from his throne.
Oddly enough, Hulk might actually be able to hit Galactus hard enough that he notices that he's been hit. But that's about as far as the fight goes. Galactus would see him as nothing more than a little green annoyance to be flicked away like a gnat.
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 ...
Galactus proved more than a match for Darkseid - who had ample opportunity to utilize his greatest powers and even try to turn the Silver Surfer to his will - and the Devourer of Worlds only spared his foe once it became clear that he had nothing to gain by continuing their conflict.
However, Thanos is still standing, and he forces Odin to unleash the full might of his power, the Odinforce. In an epic sequence, Thanos keeps advancing toward his foe, withstanding blast after blast of deadly energy. In the end, Odin is too strong, and Thanos is clearly beaten.
One of the coolest moments in Marvel's Fantastic Four cartoon from the 1990s was when Ghost Rider shows up and basically takes down Galactus right away using his Penance Stare, or, as how fans often describe it, essentially "one punches" him...
When the two faced each other in the past, Thor beat Juggernaut by generating an anti-magic whirlwind with his hammer, effectively removing Cain's magical invulnerability. Mjolnir's enchantment also makes it an immoveable object - the perfect counter to an unstoppable force like the Juggernaut.
So while Juggernaut is much more powerful, and would normally be able to win in a fight, Colossus could convince Cyttorak to transfer his power, or even cut off Cain Marko's connection to Cyttorak. Cain Marko would be left as a normal human. Colossus would still be a powerful mutant.
Originally Answered: Can Magneto defeat Galactus by using Galactus' suit against him and crush him? No. His armor isn't real. Galactus is a cosmic Abstract being, and his form at any given moment is a function of the limited mortal brain processing the impossible.
Also Galactus might not be bound to the rules of the hammer as he isn't a person but a force of nature. The force of 'equity'. So he should very well be able to lift it by one way or another.
The question depends on what power level Galactus is operating on. At his most powerful level, Zeus doesn't stand a chance. The theory is, a full powered Galactus is equal to Eternity. Even an ampt-up Galactus, one who could take on four Celestial's, would be to much for Zeus.
