Super-charged with the six Infinity Stones, Thanos easily trounced Galactus, imprisoning him alongside other cosmic beings, including the In-Betweener and two Celestials.
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 ...
With just the flick of a finger, Thanos could make Galactus disappear in an instant. With the might of all the Infinity Stones and his natural strength, Thanos is nearly unstoppable, and arguably no single hero or villain in the Marvel world could defeat him alone.
Without the Infinity Gauntlet, Thanos stands little chance against Prime Odin. Odin is stated to be able to shatter the Earth. And he turned Frigga into stars. He has devastated while worlds, laid waste to kingdoms and destroyed demons and monsters.
Although he is an extremely skilled marksman, Clint Barton is often considered to be the weakest member of the team seeing as he's just a regular guy with a bow and arrow. That certainly means that Hawkeye one of the weakest Avengers.
Thanos and Hulk have clashed several times in Marvel lore, with Thanos even admitting he was scared to face the Hulk before acquiring the Infinity Stones. While Thanos is usually the victor, it's generally down to him using superior tactics and technology, rather than simply possessing greater physical strength.
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.
Thanos would probably decimate Deadpool over and over, but with the merc's regenerative ability it would only be a matter of time until Deadpool strikes the final blow and wins this bout.
Hela is Thanos' superior in every way. Her power set is much more versatile. While Thanos would have to get within combat range to damage her, she could attack from a distance with her blades. These blades were capable of effortlessly piercing through Uru.
Even though there are threats more powerful than Galactus and the Celestials in Marvel Comics, Galactus has never feared anything as much as he's feared Tiamut.
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.
Just looking at the numbers, Darkseid would win. His Omega Beams wipe out anything they hit from existance, or in the case of Batman send that person back in time.
Odin stands a good chance at defeating a moderately-fed Galactus. Odin has been stated to be equal to a moderately-fed Galactus. Though Galan did withstand a powerful headbutt from Odin. The Devourer had just consumed one planet before that.
Thanos practically feels nothing from having the adamantium claws lunged into his chest. In retaliation, he turned Wolverine's bones into rubber - killing the previously unkillable hero in a matter of seconds.
In the end, Deadpool wasn't worthy. While he seemingly had control of Mjolnir and the strength of Thor, it was all a mirage put on by Loki to distract Thor.
With both Thor and Odin doing a job that only one was likely needed for, the pair easily pin the symbiote and weaken Thanos long enough for Phoenix to throw her burning body at the villain. The resulting explosion splits them apart and defeats Venom, stopping Thanos from carrying out a planet-wide slaughter.
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.
The simple answer is no. Yes, Hulk absolutely smashes Thor to the ground with Mjolnir, but, he's holding both Thor and the hammer. Hulk wouldn't have been able to lift Mjolnir by himself, but since the God of Thunder had a firm grip on it as well, he was able to use it as a weapon against his teammate.
He simply wanted him dead at all costs because he was his biggest threat. As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
Even in the few times he's faced Superman, the green monster has lost. It's no fault of the Hulk's, but Superman is called Superman for a reason. Unless he had kryptonite or a magic-user by his side, Hulk would usually fall to the DC Hero - although, he'd put up a hell of a fight. Superman wins.
