Galactus Galactus is literally the Devourer of Worlds. He has even taken on four Celestials and defeated them by absorbing the powers of planets. After all, he can even bring back life to otherwise dead planets. He is also the oldest living entity of the Marvel Universe.
The Celestials of Earth-4280 were convinced they were gods and attempted to conquer the Multiverse by use of the Bridge, a device created by Reed Richards that allows its users to observe and enter alternate worlds. They were defeated by the combined forces of Galactus and a Franklin Richards from an alternate future.
Galactus Is More Powerful Than The Celestials.
Hmm, The One Above All (Celestial) is the most powerful Celestial. Galactus was fighting 4 Regular Celestials and defeated 2 but the other 2 fused and he got clapped.
Arishem is the most powerful of the Fourth Host, but he is not the most powerful Celestial. The Dreaming Celestial, one of Arishem's subordinates from the Second Host, managed to defeat him. Also, the power and size of Fourth Host are nothing compared to other, higher level Celestials such as Exitar.
The heroes try to stop the Progenitor several times, but their efforts are futile, as a Celestial is simply too powerful to be harmed or killed. However, this is not necessarily true. In fact, Thor owns a weapon that was created with the exact purpose of killing Celestials, and he used it effectively in the past.
Apocalypse states that the Hulk's power/energies can challenge or possibly even overcome the celestials themselves.
As the leader of the Celestials “Host” form, Arishem the Judge travels to Earth over the course of four visits to judge whether they are worthy of existence.
In the Infinity Conflict storyline, Astral Regulator Thanos defeated The One Above All. This was achieved by using the powerful artifacts of creation known as the Astral Regulators, which The One Above All created to prevent the universes from colliding with each other and causing destruction.
This is why Wanda's powers are so strong, but her genetic disposition - which may be the beginning of the development of mutants - also accentuates her abilities. Besides, Wanda's anger has increased her power level, and WandaVision just revealed that she now could hold her own against a Celestial.
Galactus is likely to win in a fight against a single Celestial as he has defeated a Celestial in the past. But against multiple Celestials, he doesn't stand a chance. It is often said that Galactus is somewhere at the level of a Celestial and is quite possibly a bit stronger than most Celestials.
ETERNALS (1976) referred to the Celestials as “space gods,” but that doesn't mean they're gods as we define the term. However, they are cosmic beings of immense power whose size and scope defy human perception. They may not be the almighty, but they have directly influenced the course of human history.
4 DEFEATED: BLACK BOLT
His immensely powerful voice can shatter planets, which is a useful level of power to have when going up against a Celestial. Unfortunately for Black Bolt, he only ever defeated Celestials against his will.
In his final battle against all life in the galaxy, Thanos turned a hero fans will know from the MCU into a shocking weapon against the Celestials. In his greatest and most devastating bid for power, Thanos proved one Marvel hero is the ultimate destroyer of Marvel's godlike Celestials.
Celestials are weirdly vulnerable to vampires, with a recent lore change hinting that this may mean the Elder Gods are their opposite number.
So long as the Spirit of Vengeance resides inside them, their human host has the potential to physically live forever. As an added bonus, they remain ageless. In Ghost Riders: Heavens on Fire #6, Johnny Blaze states that since God created the Ghost Riders, only God can destroy them.
Zeus can be defeated, the One Above all cant be. He is truly omnipotent, and thus he cant be beaten.
Arishem is one of two Celestials who have the right and ability to judge which planet's civilization will live and which will die. Arishem's function is to act as the leader of Celestial landing parties and has led all Four Celestial Hosts on Earth.
Celestials are powerful cosmic beings created by the First Firmament.
When it comes to the grand cosmic hierarchy, the Celestials sit fairly high, but the Living Tribunal sits above them. As such, anyone above them on that celestial ladder has the ability to defeat them and wipe them from all existence.
While the Hulk has god-level powers and strength, the hero is not an official god in the same way Hercules, Thor, Knull, or the Jade Giant's own god-like being, the One Below All, are.
In the cosmic hierarchy Odin is below celestials.
well no, since Galactus was heavily amped up by eating 4 planets. And that's why he was able to kill a regular celestial otherwise Celestial would've won. So Coming to the conclusion, as I've already proved above that an Average Celestial>Non amped Galactus. There's no need for Celestials to be afraid of Galactus.
