But, at that point, Thanos had already proved that he doesn’t need the Infinity Gauntlet to put up a fight against Galactus, and the fight that proves it is insanely epic.

Annihilationby Keith Giffen and Andrea DiVito
When Annihilus makes a play for the Marvel Universe, with the full-force of his Annihilation Wave, he recruits Thanos to do his bidding (who only agrees to buy himself time to plot against Annihilus). To prove himself to his new ‘master’, Thanos orchestrates the take-down of Galactus by unleashing two Celestials against him: Aegis and Tenebrous.The two Celestials attack Galactus so hard and so fast that the Devourer of Worlds can’t keep up, and he’s eventually defeated - though that’s far from where his story ends.
After he’s beaten,Galactus becomes the power source for Thanos' own ‘Death Star’-like weapon,as his Power Cosmic is siphoned to fuel the massive laser. By the end ofAnnihilation, however, Galactus is set free, and he obliterates Annihilus' Annihilation Wave (which is also an epic battle in this iconic event).

After the Devourer of Worlds flew through the portal that led to the Beyonder’s home dimension, he’s immediately spit back out - as if theBeyonder swatted Galactus like an annoying fly. Up until this point, Galactus hadn’t really faced anyone who could truly challenge him in a one-on-one fight, which is why he thought that he could handle someone as immensely powerful as the Beyonder. But, as this short battle quickly proved, Galactus was gravely mistaken.
4Galactus Takes On the Entire Ultimate Universe
Cataclysm: The Ultimates' Last Stand#1-5 by Brian Michael Bendis and Mark Bagley

However, he’s quickly defeated by Rick Jones aka Captain Marvel, leaving Galactus weakened and in need of sustenance. While his fight against Captain Marvel is epic, it pales in comparison to the one that takes place immediately afterward, asthat battle is against the entire Ultimate Universe.
Galactus descends upon the Earth in this new universe, and it takes the combined might of the Ultimates (including the recently disgraced Reed Richards aka the Maker) to defeat him.Cataclysmis the scariest Galactus has ever been since his debut, and his battle against the Ultimate Universe is nothing short of epic.
3Galactus is Executed by Thor for His Countless Murders Across the Cosmos
Thor#6 by Donny Cates, Nic Klein and Matt Wilson
Galactus' cosmic purpose in the Marvel Universe is to maintain balance by consuming planets, but he’s not the only one of his kind in the Marvel multiverse. An entity called the Black Winter does exactly what Galactus does, but instead of consuming planets, it consumes universes. Galactus tries to fend off this multiversal beast, but little did he know that the Black Winter was the least of his worries, ashe should have been keeping a closer eye on Thor.
During this storyline, Thor is arguably the strongest he’s ever been, and he decides that it’s time that Galactus pays for all the countless murders he’s committed across the cosmos. So,after draining Galactus of his Power Cosmic, Thor hurls Mjolnir into Galactus' chest, killing him instantly. This is more of an execution than a full-on battle, though it’s undeniably epic all the same.

Before making his presence widely known, King Chaos quietly killed a number of gods and stole their power, which is exactly what he did to Zeus.King Chaos possessed Zeus' corpse, and with his own power combined with that of the King of the Gods, Chaos easily took down Galactus, even with the Devourer of Worlds ready to unleash his full might against this immensely powerful foe.
1Galactus Goes to War Against Odin & All of Asgard Over the Galactus Seed
The Mighty Thor#1-6 by Matt Fraction, Olivier Coipel, and Khoi Pham

So, the King of Asgard sends the strongest warriors he had - Thor included - to meet Galactus on the cosmic battlefield, and the war that ensued was absolutely glorious.
The battle didn’t reach its peak, however, untilOdin joined the fight himself, as he and Galactus fought one-on-one in a true clash of the titans, ending in Odin headbutting Galactus, which sent the two of them crashing into Earth. When it comes to battles, it doesn’t get much more epic than this one, which is why it’s one of the 10 bestGalactusfights in Marvel Comics history.
